Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0020] Such as figure 1 As shown, a pressure control valve according to the present invention includes a valve body 1, a medium inlet and a medium outlet are arranged on the valve body 1, a valve core 11 is arranged in the valve body 1, and the valve core 11 can generate Move, and there is a passage in the valve core 11, which can communicate with the medium passage between the medium inlet and the medium outlet when it moves to a suitable position, and the va...

The invention provides a pressure control valve. The pressure control valve comprises a valve body and a valve element arranged in the valve body, the valve body is connected with a valve element driving mechanism through a leakage-proof piece, and the valve element driving mechanism is connected with the valve element. By arranging the leakage-proof piece, the situation that under the extreme condition, a medium in the valve body leaks into the valve element driving mechanism, and normal work of the valve is affected is avoided. Opening and closing of the valve are controlled through an air cylinder, tail gas of a generator is conveniently used for control, other external force is not needed, and cost and energy are saved. The valve can be automatically opened through automatic reset of a disc spring, and the self-feedback function is achieved. An inlet of the valve body is arranged to be the conical opening, a conical piece is arranged on the valve element to be matched with the conical opening, the throttling effect is achieved, the sealing effect of the valve is controlled conveniently, and the medium outlet pressure of the valve can be reduced. The valve belongs to a mechanical valve, can replace an electromagnetic valve to be used in part of using environments, and can effectively solve the problem that the valve cannot work when a circuit is disconnected.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a pressure control valve. Background technique [0002] In the fluid medium transmission pipeline in the industrial field, it is necessary to quickly control the on-off of the fluid in the pipeline system through the pressure control valve, so the sealing and pressure control of the valve are strictly required. However, the pressure control valves in the prior art are prone to poor sealing and medium leakage after being used for a long time, thereby affecting the normal operation of the valve. Contents of the invention [0003] In view of the above technical problems, the present invention proposes a pressure control valve to solve the problem that the pressure control valve in the prior art is prone to medium leakage and thus affects the normal operation of the valve. [0004] In order to achieve the above object, the technical solution of the present invention is achieved in ...
