The pipeline of the oil field is provided with a plurality of turbine flowmeters, the single treatment of one turbine flowmeter takes 30-90 minutes, and the oil well can only stop mixing liquid during the period, so that the normal production of the oil well is seriously influenced.

Therefore, in the related art, the turbine flow meter has the technical problem that the turbine blade blockage is difficult to clean. The embodiment of the application provides a turbine flowmeter and a turbine flowmeter, which can solve the technical problems to a certain extent at least.

The application is described below with reference to specific embodiments in conjunction with the accompanying drawings:

The embodiment of the application provides a turbine flowmeter 100, and the turbine flowmeter 100 provided in the embodiment of the application can clean the blocked turbine blade 120 through the first cleaning port 110d and the first sealing cover 130, so that the cleaning of the turbine blade 120 is more convenient and simpler.

As shown in FIG. 1, the turbine flow meter 100 of the present application includes a housing 110, turbine blades 120, a meter body 170, and a first seal cover 130. The housing 110 is provided with a flow passage 110a and a water inlet 110b and a water outlet 110c communicating with the flow passage 110 a. The turbine blade 120 is positioned within the flow passage 110a and is rotatably coupled to the housing 110. The housing 110 is further provided with a first cleaning opening 110d communicated with the flow channel 110a, at least a portion of the turbine blade 120 can be exposed through the first cleaning opening 110d, and the meter 170 is used for detecting the rotational speed of the turbine blade 120. The first sealing cover 130 is detachably connected with the housing 110, and covers the first cleaning opening 110d.

The water inlet 110b and the water outlet 110c are configured to communicate with an external conduit such that water flow in the external conduit enters the flow channel 110a through the water inlet 110b, passes through the turbine blades 120, and finally flows out of the water outlet 110 c. The structure of the gauge 170 is various, and it is known to those skilled in the art that the gauge 170 is not limited in the present application, and the function of the gauge 170 is to detect the rotation speed of the turbine blade 120, and convert the rotation speed of the turbine blade 120 into a flow value of the fluid, and display the flow value on the gauge, so that the personnel can observe and read.

Typically, the meter body 170 includes components such as a sensor, a signal converter, and a display unit, where the sensor monitors the rotational speed of the turbine by magnetic, optical, or hall effect techniques, and the signal generated by the sensor is converted to a readable flow value by the signal converter and finally displayed on the flowmeter. In some embodiments, the meter 170 includes a housing, a counter, a glass panel, an induction coil, a permanent magnet, an amplifier, and the like, and when water flows in the flow channel 110a, the water flow drives the turbine blade 120 to rotate, the turbine blade 120 rotates to cut magnetic lines of force, so that the magnetic resistance of the magnetic circuit changes, and a sensing signal is generated, amplified and shaped by the amplifier, and sent to the counter or the frequency meter to display the total integrated flow.

The manner of detachable connection between the first sealing cover 130 and the housing 110 is various, such as clamping, screwing, bonding, etc., and is not limited in the present application. It should be appreciated that the first seal cap 130 is hermetically connected to the housing 110 to prevent water within the flow path 110a from leaking out of the gap between the first seal cap 130 and the housing 110.

At least a portion of the turbine blade 120 can be exposed through the first cleaning port 110d, which means that the turbine blade 120 can be observed through the first cleaning port 110d after the first sealing cover 130 is removed, and the turbine blade 120 is exposed in the field of view. After the turbine flowmeter 100 is designed in this way, when the turbine blade 120 is blocked by mud, sand and the like, the first sealing cover 130 is disassembled, so that the condition inside the turbine blade can be observed, the turbine blade and the periphery of the turbine blade can be cleaned, the shell 110, the turbine blade 120, the surface body 170 and the like are not required to be disassembled, the turbine blade is cleaned more conveniently, the blocking recovery time of the turbine blade 120 is shortened, the cleaning efficiency of the turbine blade 120 is improved, and the oilfield production efficiency is improved.

The manner in which the turbine flow meter 100 of the present application is connected to an external conduit is varied. In some embodiments, the water outlet 110c side and the water inlet 110b side of the housing 110 are provided with flange edges, and sealing rubber rings are arranged on the flange edges, so that the housing 110 and an external pipeline are fixedly connected and hermetically connected in a bolt connection mode. In some embodiments, the water outlet 110c side and the water inlet 110b side of the housing 110 are fixedly connected and hermetically connected with the external pipe by welding.

In some embodiments, a jackscrew 140 is fixedly connected to a side of the first sealing cover 130 near the turbine blade 120, and the first sealing cover 130 can drive the jackscrew 140 to extend into the flow channel 110a and abut against the turbine blade 120 to rotate the turbine blade 120. After such design, when the blocking of the turbine blade 120 is not serious, the first sealing cover 130 drives the jackscrew 140 to move towards the turbine blade 120 and to abut against the turbine blade 120 to push the turbine blade 120 to rotate, so that the turbine blade 120 is separated from the blocking. After the turbine blade 120 is separated from the blocking, the first sealing cover 130 drives the jackscrew 140 to move away from the turbine blade 120, and the jackscrew is positioned in the first cleaning opening 110d or in the runner 110a to avoid interference with rotation of the turbine blade 120. By the design, when the turbine blade 120 is blocked, valves on the upstream and downstream of the turbine flowmeter 100 can not be closed, the turbine blade 120 blocking fault can be treated on line, the turbine blade 120 blocking is simpler to treat, and water flows normally during treatment, so that oilfield production work is guaranteed.

In order to achieve the function that the first sealing cover 130 can drive the jackscrew 140 to extend into the flow channel 110a and abut against the turbine blade 120 to rotate the turbine blade 120, in some embodiments, the first sealing cover 130 and the housing 110 are slidably connected along a direction towards the turbine blade, and a limiting structure is disposed on a sliding path, where the limiting structure prevents the first sealing cover 130 from being separated from the housing 110 after sliding. After the design, when the turbine blade 120 needs to be abutted to rotate, the first sealing cover 130 is pushed towards the turbine blade 120, and the first sealing cover 130 can drive the jackscrew to slide towards the direction of the turbine blade 120, so that the turbine blade 120 is pushed. In some embodiments, as shown in FIG. 1, the first seal cap 130 is screwed to the housing 110, and rotation of the first seal cap 130 drives the jackscrew to extend into the flow channel 110a and abut against the turbine blade 120 to rotate the turbine blade 120. That is, the first cleaning port 110d is internally provided with an internal thread, and the first sealing cap 130 is provided with an external thread; or the first sealing cover 130 is provided with an internal thread, and the first cleaning port 110d is provided with an external thread, and the internal thread is matched with the external thread, so that the first sealing cover 130 is in threaded connection with the shell 110. After the threaded connection, when the first sealing cover 130 is rotated in different directions, the sealing cover can move towards the turbine blade 120 or move away from the turbine blade 120, so that the first sealing cover 130 can drive the jackscrew 140 to move towards the turbine blade 120 or move away from the turbine blade 120. After such design, when the blocking of the turbine blade 120 is not serious, the first sealing cover 130 can be screwed, so that the first sealing cover 130 drives the jackscrew 140 to move towards the turbine blade 120 and is abutted on the turbine blade 120 to push the turbine blade 120 to rotate, and the turbine blade 120 is separated from the blocking. After the turbine blade 120 is separated from the blocking, the first sealing cover 130 is reversely screwed to drive the jackscrew 140 to move away from the turbine blade 120, and the jackscrew is positioned in the first cleaning opening 110d or in the runner 110a to avoid interference with rotation of the turbine blade 120.

It should be understood that the first sealing cover 130 and the housing 110 are screwed together while ensuring a sealed connection, so as to prevent water from overflowing from the first sealing cover 130, and the first sealing cover and the housing may be screwed together or sealed by providing a sealing ring. As shown in fig. 3, in some embodiments, three sealing rubber rings are sleeved on one side of the first sealing cover 130 close to the jackscrew 140, an external thread is provided on one side of the first sealing cover 130 far away from the jackscrew 140 and is in airtight connection with the first cleaning port 110d, and gaps between the first sealing cover 130 and the first cleaning port 110d are sealed by the three sealing rubber rings during rotation of the first sealing cover 130.

In some embodiments, as shown in fig. 3, the jackscrew 140 is an elastic jackscrew 140, and the jackscrew 140 is wavy. That is, the top thread 140 has elasticity, is not easy to deform, and can recover to an original state after losing the acting force, and the top thread 140 is in a wave shape. After such design, as shown in fig. 2, the jackscrew 140 can deform when abutting against the turbine blade 120, and is located above or below the turbine blade 120, and the wavy shape can apply acting force for driving the turbine blade 120 to rotate to the turbine blade 120 when the turbine blade 120 extends forwards or backwards, so that the turbine blade 120 is beneficial to being quickly separated from the blockage; when the turbine blade 120 is severely blocked, the turbine blade 120 can vibrate, and the falling of impurities and the like on the turbine blade 120 can be promoted, so that the turbine blade 120 is promoted to be separated from the blocking. By such design, since the jackscrew 140 is an elastic jackscrew 140, direct rigid contact of the jackscrew 140 with the turbine blade 120 is also avoided, and the turbine blade 120 is damaged.

In use of the turbine flowmeter 100, not only the turbine blades 120 but also the flow path 110a in the housing 110 is easily blocked by mud, sand, or the like, and particularly the turbine flowmeter 100 having a small inner diameter in the middle of the flow path 110a as shown in fig. 2. In the related art, if the flow passage 110a is blocked, the entire turbine flow meter 100 needs to be detached from the pipeline and then cleaned, which is troublesome.

In some embodiments, a second cleaning port 110e is further provided on a side of the housing 110 near the water inlet 110b, which communicates with the flow channel 110 a. The turbine flowmeter 100 further includes a second sealing cover 150, where the second sealing cover 150 is detachably connected to the housing 110, and covers the second cleaning opening 110e. After the design, when the runner 110a is blocked, the upstream and downstream valves of the turbine flowmeter 100 are closed, then the second sealing cover 150 is disassembled, and an iron wire, a plastic rod and the like are inserted into the second cleaning opening 110e to clean the runner 110a, so that the runner 110a is convenient to dredge.

In some embodiments, the axis of the second purge port 110e is disposed at an angle to the axis of the flow passage 110a, with the axis of the second purge port 110e oriented toward the turbine blade 120. The angled arrangement does not include a perpendicular arrangement, that is, the axis of the second clearance port 110e is not perpendicular to the axis of the flow passage 110a, and at the same time the second clearance port 110e is inclined toward the turbine blade 120. The axis of the second cleaning opening 110e and the axis of the runner 110a form an included angle, so that tools such as iron wires and plastic rods can conveniently extend into the runner 110a and move along the runner 110a, and the runner 110a is conveniently cleaned. The axial direction of the second cleaning opening 110e faces the turbine blade 120, so that tools such as iron wires and plastic sticks can conveniently penetrate into the vicinity of the turbine blade 120 to clean impurities in the vicinity of the turbine blade 120.

In some embodiments, a third cleaning opening 110f is further provided on a side of the housing 110 near the water outlet 110c and is in communication with the flow channel 110 a. The turbine flowmeter 100 further includes a third sealing cover 160, where the third sealing cover 160 is detachably connected to the housing 110 and covers the third cleaning opening 110f. After the design, when the flow channel 110a is blocked, the second sealing cover 150 and the third sealing cover 160 can be simultaneously opened, and impurities in the flow channel 110a can be simultaneously cleaned through the second cleaning opening 110e and the third cleaning opening 110f, so that the dredging efficiency of the flow channel 110a is improved.

In some embodiments, the axis of the third purge port 110f is disposed at an angle to the axis of the flow passage 110a, with the axis of the third purge port 110f oriented toward the turbine blade 120. The angled arrangement does not include a perpendicular arrangement, that is, the axis of the third clearance port 110f is not perpendicular to the axis of the flow passage 110a, and at the same time the third clearance port 110f is inclined toward the turbine blade 120. The axis of the third cleaning opening 110f is arranged at an included angle with the axis of the runner 110a, so that tools such as iron wires, plastic rods and the like can conveniently extend into the runner 110a and move along the runner 110a to clean the runner 110a. The axial direction of the third cleaning opening 110f faces the turbine blade 120, so that tools such as iron wires and plastic sticks can conveniently penetrate into the vicinity of the turbine blade 120 to clean impurities in the vicinity of the turbine blade 120.

In some embodiments, the distance from the second clearance port 110e to the turbine blade 120 is greater than the distance from the third clearance port 110f to the turbine blade 120. When the flow passage 110a is blocked, the elastic dredging piece shown in fig. 4 can be adopted to dredge the flow passage, the elastic dredging piece is in a wave shape as a whole, a handheld seat which can be held by hand is fixedly connected to the middle part of the elastic dredging piece, and the handheld seat divides the elastic dredging piece into two sections with different lengths. When the runner 110a is dredged through the second cleaning opening 110e, the hand-held seat is held by hand and rotated, and one long side of the elastic dredging piece is adopted for dredging; when the flow passage 110a is opened through the third cleaning port 110f, the hand-held holder is held by hand and rotated, and the short side of the elastic opening member is used.

In some embodiments, as shown in fig. 2, the housing 110 includes a first housing 111, a second housing 112, and a third housing 113, and the flow passage 110a, the water inlet 110b, and the water outlet 110c are provided on the second housing 112. The first housing 111 is provided with a first installation cavity 111a communicating with the flow channel 110a, and the second housing 112 is located in the first installation cavity 111a. The first shell 111 and the third shell 113 are detachably connected and clamped to the second shell 112, the second shell 112 is in airtight connection with the first shell 111, and the turbine blade 120 is rotatably connected to the second shell 112; the second housing 112 and the third housing 113 enclose a second mounting cavity 113a, the second mounting cavity 113a being used for mounting the watch body 170. So designed, the second housing 112 is fixed between the first housing 111 and the second housing 112 by the combined action of the first housing 111 and the third housing 113. The airtight connection of the second housing 112 and the inner wall of the first installation cavity 111a ensures that water in the flow channel 110a does not flow out from the gap between the second housing 112 and the first housing 111, ensuring the tightness of the turbine flowmeter 100 of the present application. The second housing 112 and the third housing 113 enclose a second mounting cavity 113a, so that part of the components of the meter body 170 can be located in the second mounting cavity 113a, which helps to reduce the volume of the turbine flowmeter 100.

The manner in which the second housing 112 and the first housing 111 are hermetically connected is varied, and as shown in fig. 2, in some embodiments, a ring of sealing rubber is disposed on the second housing 112, and a gap between the second housing 112 and the first housing 111 is sealed by a sealing ring. In some embodiments, a sealant seal is applied between the second housing 112 and the first housing 111. The third housing 113 and the first housing 111 are also detachably connected in various manners, and may be bolted, clamped, bonded, or the like.

In some embodiments, the watch body 170 is removably coupled to the third housing 113. The watch body 170 and the third case 113 may be connected by a bolt, a clip, or the like. In some embodiments, as shown in fig. 2, an external thread 113b is formed on a side of the third housing 113 away from the first housing 111, and an adapted internal thread is formed on the watch body 170, where the third housing 113 is in threaded connection with the watch body 170. The mode of threaded connection, simple structure, processing is convenient, and threaded connection can realize airtight connection by self simultaneously, perhaps realizes airtight connection through modes such as raw material area, packing ring, helps preventing that rivers from entering into in the second installation cavity 113 a. In some embodiments, after the watch body 170 and the third housing (113) are threadably coupled, the sensor of the watch body 170 is positioned within the second mounting cavity 113a, as shown in FIG. 1.

The working principle of the turbine flowmeter 100 of the present application is: when the turbine blade 120 in the turbine flowmeter 100 of the present application is blocked, the first sealing cover 130 is screwed, so that the elastic jackscrew 140 stretches into the direction of the turbine blade 120, after the elastic jackscrew 140 is stressed, the elastic jackscrew is transformed above the turbine blade 120, so as to push the turbine blade 120 to rotate, and meanwhile, the elastic jackscrew 140 is wavy and simultaneously drives the turbine blade 120 to vibrate, so that impurities on the turbine blade 120 fall off. When the first sealing cover 130 is screwed to the limit position, the turbine blade 120 is not rotated yet, and the first sealing cover 130 is screwed repeatedly until the turbine blade 120 is separated from the jam. If the turbine blade 120 fails to be separated from the jam after being reciprocally screwed a plurality of times, the upstream and downstream valves are closed, the first sealing cover 130 is detached from the housing 110, and the turbine blade 120 is pushed to rotate or the turbine blade 120 is flushed by other means. When the flow channel 110a is blocked, the second sealing cover 150 and the third sealing cover 160 are disassembled, and the second cleaning opening 110e and the third cleaning opening 110f are penetrated through iron wires and the like, enter the flow channel 110a, and clean the flow channel 110 a; or the second sealing cover 150 and the third sealing cover 160 are disassembled, and air is blown to the flow channel 110a through the first cleaning opening 110d or the second cleaning opening 110e, so that impurities in the flow channel 110a are discharged, and the flow channel 110a is dredged.

In summary, when the turbine blade 120 of the turbine flowmeter 100 is blocked by mud, sand and the like, the first sealing cover 130 is disassembled, so that the condition inside the turbine blade can be observed, the turbine blade and the periphery of the turbine blade can be cleaned, the shell 110, the turbine blade 120, the surface body 170 and the like are not required to be disassembled, the turbine blade is cleaned more conveniently, the blocking recovery time of the turbine blade 120 is shortened, the cleaning efficiency of the turbine blade 120 is improved, and the oilfield production efficiency is improved. Through the threaded connection of the first sealing cover 130 and the shell 110 and the design of the jackscrew 140, the turbine flowmeter 100 can release the blocking of the impeller on line under the condition that the upstream valve and the downstream valve are not closed, and the turbine flowmeter 100 is further convenient to use.
