Description

FIELD OF TECHNOLOGY

[0001] The utility model relates to the field of hot water sanitary ware valves, in particular to a two-way combination valve with axial water inlet.

BACKGROUND OF THE INVENTION

[0002] Valves are used to turn the flow of water on and off. Traditional hot water sanitary wares often have multiple outlets. When using the valve stem to control water flow on and off, multiple redirecting valve portions are required to be positioned downstream of the valve stem to control different water outlet paths. Such an arrangement increases the production cost and complexity of the conduit of the hot water sanitary ware, furthermore, it increases the cost of use for users, for example, when using the hot water sanitary ware, users must manually operate the redirecting parts of the valve if the outlet is to be switched, which is inconvenient. .

[0003] In particular, for some hot water sanitary wares equipped with hand spray nozzles (pop-up nozzle), in order to ensure the water pressure and strength of the hand spray (pop-up nozzle) in use, the water supply to the hand sprayer (pop-up nozzle) should be priority. However, the design of the existing parts of the valves cannot effectively guarantee the shutoff of water from other outlets downstream of the valve obturator at the time when the hand spray (pop-up nozzle) is opened separately, therefore, in order to ensure the water outlet and pressure of the hand spray (pop-up nozzle) ), it is necessary to manually switch the redirecting part of the valve to close other outlets downstream than the obturator, which causes great inconvenience to users. When reserving the outlet through the redirect valve for the hand sprayer (pop-up nozzle), users need to firstly switch the redirect valve, and secondly, press the control handle of the hand sprayer (pop-up nozzle) being used, because the hand sprayer (pop-up nozzle) nozzle) includes a control handle, which further increases the inconvenience of using a manual sprayer (retractable nozzle).

ESSENCE OF THE UTILITY MODEL

[0004] In order to solve the above problems, the utility model provides a two-way axial water inlet combination valve that can directly dock with the hand sprayer (pop-up nozzle), block other outlets, and give priority to the hand spray gun (pop-up nozzle) outlet when the hand sprayer (pop-up nozzle) nozzle) is on.

[0005] To achieve the above goals, the following technical solution is proposed: a two-way combined valve with an axial water inlet, containing a valve body, while the valve body is equipped with a valve seat at its far downstream end, and the valve seat is provided with two inlet and outlet channels, the valve body accommodates a movable element controlled by a valve handle and a fixed element, one side of which is adjacent to the valve seat and the other side corresponds to the fixed element, while the fixed element is equipped with two water inlets, respectively connected to the inlet channels, and a water outlet connected to an outlet channel, each inlet channel extending from the water inlet to the edge of the valve seat facing away from the valve body, the axes of the inlet channels being parallel to the axis of the valve body; the outlet channel has a conical nozzle, in which the end of the small diameter faces the end of the outlet channel away from the water outlet, and the end of the large diameter is connected with the outlet of the water, while the cross section of the end of the small diameter of the conical nozzle is smaller than the cross section of the outlet channel, the cross section the cross section of the outlet of water and the cross section of the end of the large diameter of the conical nozzle, and the axis of the end of the small diameter of the conical nozzle is coaxial with the axis of the end of the outlet channel away from the water outlet; the valve seat is additionally provided with a secondary outlet channel, which communicates with the inner wall of the outlet channel between the end of the large diameter and the end of the small diameter of the conical nozzle.

[0006] In the above construction, the valve handle controls the sliding of the movable member corresponding to the fixed member to effect connection or disconnection between the water inlet and the water outlet; the outlet port is configured to connect a hand sprayer (pop-up nozzle) and the secondary outlet port is configured to connect a downstream outlet or redirect valve portion. When the outlet port connected with the secondary outlet port uses water, water flows from the water outlet to the outlet port, after passing through the conical nozzle, a high-speed and high-pressure water jet is formed, which flows out from the end of the small diameter of the conical nozzle, after entering the internal cavity at the end outlet port facing away from the water outlet. Since the hand spray (retractable nozzle) is not open, water flows in the opposite direction and flows out of the secondary outlet located between the large diameter end and the small diameter end of the conical nozzle. When the hand sprayer (retractable nozzle) is opened, water flows from the water outlet to the outlet channel, and after passing through the conical nozzle, a high-speed and high-pressure water jet is formed, which flows out from the end of the small diameter conical nozzle and directly affects the end of the outlet channel facing the side of the water outlet, and creates a negative pressure at the junction of the secondary outlet and the outlet in accordance with the Bernoulli principle, which directs all the water flow to the end of the outlet facing away from the water outlet, so when the downstream outlet of the secondary outlet port uses water, the water supply from the secondary outlet to the downstream outlet is automatically stopped when the hand sprayer (pop-up nozzle) is opened, thereby ensuring sufficient water supply for the hand sprayer (pop-up nozzle). The location of the end of the inlet in the direction from the water inlet to the edge of the valve seat in the direction away from the valve body is determined in the state where the middle part of the valve is installed.

[0007] The utility model is further arranged as follows: the inlet port includes a cold water port and a hot water port, the water inlet includes a cold water port and a hot water port; the cold water channel is in communication with the cold water hole, the hot water channel is in communication with the hot water hole; the end of the cold water channel from the cold water hole and the end of the hot water channel from the hot water hole face the same direction.

[0008] The above design can be provided with two inlet ports, which allows it to be used as the middle part of the valve for cold and hot water.

[0009] The utility model further provides that the outlet channel and the inlet channel are directed in the same direction.

[0010] In the above structure, the hand spray retractable hose (retractable nozzle) is usually stored under the mixer body, so the outlet direction is the same as the inlet direction, so that the hand spray retractable hose (retractable nozzle) can be connected to the middle part of the valve.

[0011] The utility model is further configured such that the secondary outlet port faces the outlet port or inlet port, or faces the radial direction of the valve body or valve seat.

[0012] In the above structure, the secondary outlet port is configured to supply water to another water hole of the mixer, and thus its direction can be determined according to the design of the actual mixer.

[0013] The utility model is further arranged such that the end of each inlet passage remote from the water inlet, the end of the outlet passage remote from the water outlet, and the end of the secondary outlet passage remote from the outlet connection are provided with internal threads.

[0014] In the above construction, the female thread is for connecting a water pipe.

[0015] The utility model can also be arranged such that the female thread and the valve seat are integrally formed by injection molding.

[0016] In the above structure, due to the integral structure of the internal thread and the valve seat made by injection molding, the production cost can be effectively reduced.

[0017] The utility model can also be arranged such that the female thread is formed on the threaded bushing, and the threaded bushing and the valve seat are integrally connected by injection molding.

[0018] In the above structure, the threaded bushing is preferably a brass bushing, which can improve the wear resistance of the internal thread.

[0019] The utility model is also arranged such that the large diameter end of the conical nozzle is attached to the inner wall of the outlet channel by gluing or welding.

[0020] In the above construction, in the case of using welding, ultrasonic welding is preferable, which improves production efficiency while ensuring joint strength.

[0021] The utility model is further arranged such that the conical nozzle and the valve seat are integrally formed by injection molding.

[0022] In the above structure, the conical nozzle and the valve seat integrally formed by injection molding can improve the stability of the whole structure.

[0023] A two-way combined valve with an axial water inlet in accordance with the utility model has the following advantages: the valve handle controls the sliding of the movable element relative to the fixed element, to pass or close the passage between the water inlet and the water outlet; the outlet port is configured to connect a hand sprayer (pop-up nozzle) and the secondary outlet port is configured to connect a downstream outlet or redirect valve portion. When the outlet connected to the secondary outlet port uses water, water flows from the water outlet to the outlet port, after passing through the conical nozzle, a high-speed and high-pressure water flow is formed, which flows out from the small diameter end of the conical nozzle and sprays, after entering the internal cavity at the end of the outlet port away from the water outlet, water flows in the opposite direction and flows out of the secondary outlet port located between the large diameter end and the small diameter end of the conical nozzle when the hand spray (pop-up nozzle) is not turned on. When the hand sprayer (pop-up nozzle) is turned on, water flows from the water outlet to the outlet port, high-velocity and high-pressure water flow is formed from the end of the small diameter conical nozzle and sprayed, directly affects the end of the outlet port facing away from the water outlet, and creates a negative pressure at the junction of the secondary outlet and the outlet in accordance with the Bernoulli principle, which brings all the water flow to the end of the outlet facing away from the water outlet, to realize the possibility, if there is water flow in the outlet located downstream of the secondary outlet, shut off the water supply from the secondary outlet to the downstream outlet when the hand spray (pop-up nozzle) is turned on, ensuring that there is sufficient water supply for the hand spray (pop-up nozzle). The location of the end of the inlet in the direction from the water inlet to the edge of the valve seat in the direction away from the valve body is determined in the state where the middle part of the valve is installed.

DISCLOSURE OF IMPLEMENTATION EXAMPLES

[0029] Specific embodiments of the utility model are described in more detail below with reference to the drawings and exemplary embodiments. The following embodiments are used to illustrate the utility model, but do not limit the scope of the utility model.

On FIG. 1 - Fig. 5 shows a two-way combined valve with an axial water inlet, which includes a valve body 10, a valve seat 20 located at the far downstream end of the valve body 10. The valve seat 20 is provided with two inlet ports and one outlet port 21. The valve body 10 contains a movable element 12, which is controlled by the valve handle 11. There is a fixed element 13, one side of which is adjacent to the valve seat 20, and the other side corresponds to the movable element 12. The fixed element 13 is provided with two water inlets connected to the inlet channels, and a fixed water outlet 131 connected to the outlet channel 21. One end of the inlet port in the direction away from the water inlet extends to the edge of the valve seat 20 in the direction away from the valve body 10. The axis of the inlet port is parallel to the axis of the valve body 10. The outlet channel 21 is provided with a conical nozzle 22 having a small diameter end and a large diameter end. The small diameter end of the conical nozzle 22 faces the end of the outlet channel 21 in the direction away from the water outlet 131, and the large diameter end of the conical nozzle 22 communicates with the water outlet 131. The cross section of the small diameter end of the conical nozzle 22 is smaller than the cross section of the outlet channel 21, the cross flow of the water outlet 131 and the cross flow of the large diameter end of the conical nozzle 22. The axis of the small diameter end of the conical nozzle 22 is coaxial with the axis of the end of the outlet channel 21, located away from the outlet 131 water. In addition, the valve seat 20 is further provided with a secondary outlet port 23 that communicates with the inner wall of the outlet port 21 at a location located between the large diameter end and the small diameter end of the conical nozzle 22.

Since the hand sprayer (pop-up nozzle) is not open, after entering the internal cavity at the end of the outlet channel 21 facing away from the water outlet 131, the water flows in the opposite direction and flows out of the secondary outlet channel 23 located between the end large diameter and the small diameter end of the conical nozzle 22. When the hand sprayer (retractable nozzle) is opened, water flows from the water outlet 131 to the outlet channel 21, after passing through the conical nozzle 22, a high-speed and high-pressure water jet is formed, which flows out from the end of the small diameter conical nozzle 22, directly acting on the end of the outlet channel 21 facing away from the water outlet 131.

[0042] In the above construction, the threaded bushing 26 is preferably a brass bushing to improve the wear resistance of the female thread 261.

[0043] In the present embodiment, the large diameter end of the conical nozzle 22 is attached to the inner wall of the outlet port 21 by gluing or welding.

[0044] In the above construction, in the case of using welding, ultrasonic welding is preferable, improving production efficiency while ensuring joint strength at the same time.
