[0002] The operating torque of the electric valve is larger than that of the ordinary valve. The opening and closing speed of the electric valve can be adjusted. The structure is simple and easy to maintain. It can be used to control the flow of various types of fluids such as various corrosive media and radioactive media. During the operation of the traditional pneumatic valve, due to the buffering characteristics of the gas itself, it is not easy to be damaged due to jamming, but it must have a gas source, and its control system is also more complex than that of the electric valve.

[0003] The utility model patent with the patent number CN214500192U discloses an electric valve, including a valve body. A first fixing plate is fixedly connected to the top of the valve body. The first fixing plate is connected to a second fixing plate through a connecting mechanism. The second fixing plate is located directly above the first fixing plate. The first fixing plate is connected with a control component, and the control component is connected with a valve shaft through a driving mechanism. Through the coordinated use of the control motor, the reduction gear assembly, the sector gear, the valve shaft, the second fixing plate and the elastic spring, the utility model realizes the combination of automatic control and electric remote control of the valve, solves the problem that valves in the prior art all need manual control, which is time-consuming and laborious, and improves the practicability of the device.

[0004] In order to conveniently control the on-off of the pipeline fluid, an electric valve will be used. Although the device in the above patent improves the control effect of the valve, after long-term use, it is easy to cause corrosion or deformation of the valve plate. After the valve plate is damaged, it is more cumbersome to replace the valve body, reducing the maintenance efficiency of the electromagnetic valve. Therefore, we provide an electric valve with the function of quick disassembly of the valve plate to solve the above problems. Content of the Utility Model
