Abstract
The utility model discloses a sealed container liquid level measurement device has single flange liquid level changer, wherein: the downside at sealed container is installed to single flange liquid level changer, and pipe, the single flange liquid level changer negative pressure of valve connection side are pressed through drawing in sealed container upside exhaust hole, the exhaust hole still communicates the drainer. Compared with the prior art, gaseous phase pressure influences the measuring in having solved the container, has low price, installation, the simple advantage of maintenance.
Description
Technical field
The utility model belongs to chemical plant technical field of liquid level measurement, is specifically related to a kind of closed vessel liquid level measurement mechanism.
Background technology
Measure the liquid level of liquid in closed container in Chemical Manufacture, usually select differential pressure transmitter, except will bearing the pressure of liquid level difference formation, also will consider the effect of gaseous pressure in container; Need the pressure of air pressure and the point of pressure below that upper vessel portion is drawn to compare, just can measure the true liquid level of liquid.Another method is two flange liquid level transmission devices, but the dismounting of this instrument, adjustment expense people are time-consuming, and kapillary is fragile, while expensive.
Summary of the invention
For solving the above-mentioned technological deficiency that prior art exists, the purpose of this utility model is to provide a kind of closed vessel liquid level measurement mechanism, solves gaseous pressure in container to the impact of measuring, have cheap, install, safeguard simple advantage.
For achieving the above object, the technical solution adopted in the utility model: this closed vessel liquid level measurement mechanism, there is single flange liquid level transmission device, it is characterized in that: described single flange liquid level transmission device is arranged on the downside of closed container, on the upside of closed container, vent port connects single flange liquid level transmission device suction side by pressure guiding pipe, valve, and described vent port is also communicated with drainer.
Described drainer is transparent visible glass jar, and the pressure guiding pipe be connected with vent port on the upside of closed container has the straight section tilted upward, and the end of this straight section connects described drainer, and this drainer connects liquid feeding mouth by valve.
The described straight section pressure guiding pipe tilted upward becomes the angle of 5 ~ 10 ° with horizontal line.
Adopt the beneficial effect of technique scheme: this closed vessel liquid level measurement mechanism adopts single flange liquid level transmission device to measure the liquid level in closed container, during installation, single flange liquid level transmission device is arranged on (malleation side) on the downside of closed container, on the upside of closed container, vent port is connected to single flange liquid level transmission device suction side by pressure guiding pipe.Solve two flange liquid level transmission device time-consuming the dismounting of instrument, adjustment expense people, kapillary is fragile, and expensive problem.The pressure guiding pipe be connected with vent port on the upside of closed container has the straight section tilted upward in 5 ~ 10 °, the measurement for negative pressure chamber's drying can be solved, when upper vessel portion condensation effect is bad, drainer is flowed into along pressure guiding pipe through negative pressure chamber's connecting pipe straight section after the condensed fluid condensation that in container, gas produces, cause the full liquid of negative pressure chamber, when closed container is negative pressure, connecting pipe inclination straight section adopts and becomes the angle of 5 one 10 ° to upwarp installation with horizontal line, condensed fluid can backflow in closed container, meets explained hereafter needs.Fill condensed fluid (or silicone oil) for drainer and measure liquid level by the way of negative transfer, summer high-temperature easily makes the steam raising of suction side condensed fluid season, causes liquid level to indicate higher.Change existing metal condensation tank into transparent visible glass jar, observe the steam raising situation of condensed fluid during operation, supplement at any time, observe easy to operate.Technical solutions of the utility model compared with prior art, have cheap, install, safeguard simple advantage, also solve the impact of gaseous pressure in container simultaneously, can meet and liquid level is required it is not occasion very accurately.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another kind of structural representation.
Embodiment
Closed vessel liquid level measurement mechanism as shown in Figure 1, there is single flange liquid level transmission device 2, described single flange liquid level transmission device is arranged on the downside of closed container 1, on the upside of closed container, vent port 7 connects single flange liquid level transmission device 2 suction side by pressure guiding pipe 6, first valve 5, and described pressure guiding pipe 6 is also communicated with drainer 3 by the second valve 4.
As shown in Figure 2, described drainer 3 is transparent visible glass jar, transparent visible glass jar, observes the steam raising situation of condensed fluid, supplement at any time, observe easy to operate during operation.The pressure guiding pipe 6 be connected with vent port on the upside of closed container has the straight section tilted upward, described in the straight section pressure guiding pipe that tilts upward become the angle of 5 ~ 10 ° with horizontal line, condensed fluid can backflow in closed container, meets explained hereafter needs.。The end of this straight section connects described drainer 3, and this drainer 3 connects liquid feeding mouth 9 by the 3rd valve 8.Described drainer 3 is communicated with single flange liquid level transmission device 2 by pressure guiding pipe, and another outlet of pressure guiding pipe is controlled by the second valve 4.
