Description
Technical Field
[0001] The utility model relates to the technical field of flow control devices, in particular to a two-way pressure compensation valve. Background Technique
[0002] A pressure compensation valve is a device that automatically adjusts the flow rate and pressure in a pipeline by regulating the size of the valve orifice. The main mechanism of the pressure compensation valve is to regulate the size of the valve orifice by the pressure acting on the spring. The spring will gradually compress under the action of the pressure, providing a balancing force for the valve.
[0003] In common pressure compensation valves, the spring will gradually compress under the action of pressure, gradually opening the valve orifice to increase the valve flow rate. Common pressure compensation valves do not have a port for shunting when the spring is under a large pressure, resulting in a low flow discharge efficiency. The spring is easily damaged when it is under high pressure for a long time. Therefore, a two-way pressure compensation valve is needed to solve the above problems. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a high-speed pretreatment water treatment device to solve the problems raised in the above background technique: common pressure compensation valves do not have a port for shunting when the spring is under a large pressure, resulting in a low flow discharge efficiency, and the spring is easily damaged when it is under high pressure for a long time.

The purpose of such a setting is as follows: By providing the first connecting valve sleeve and the second connecting valve sleeve, when the valve stem assembly bears a large pressure, the second valve stem and the first valve stem can be pushed to contract the return spring. When the lifting collar provided on the second valve stem is pushed past the throttle hole provided on the second connecting valve sleeve, pressure relief can be achieved through the second connecting valve sleeve. When the pressure is too high, when the lifting collar provided on the second valve stem enters the first connecting valve sleeve, since the inner cavity of the first connecting valve sleeve is slightly larger than the inner cavity of the second connecting valve sleeve, and at this time the lifting collar provided on the first valve stem has moved away from the throttle hole provided on the first connecting valve sleeve, pressure relief can be achieved simultaneously through the first connecting valve sleeve and the second connecting valve sleeve at this time, improving the pressure relief efficiency and preventing the return spring from being damaged due to long-term compression.

One end of the first valve stem 501 is provided with a connecting through groove 502, and a return spring 503 is connected between the connecting through groove 502 and the inner wall of the positioning screw tube 1. One end of the second valve stem 504 is fixedly connected with a connecting screw tube 506. One end of the first valve stem 501 close to the connecting screw tube 506 is provided with connecting threads, and one end of the first valve stem 501 is threadedly connected with the connecting screw tube 506.

[0021] The working principle of the present utility model: By providing the first connecting valve sleeve 2 and the second connecting valve sleeve 3, when the valve stem assembly 5 bears a large pressure, the second valve stem 504 and the first valve stem 501 can be pushed, so that the return spring 503 contracts. When the lifting collar 505 provided on the second valve stem 504 is pushed past the throttle hole 4 provided on the second connecting valve sleeve 3, pressure relief can be carried out through the second connecting valve sleeve 3.
