Description

Technical Field

[0001] The utility model belongs to the technical field of electric gate valves, and in particular relates to a sealing component of an electric gate valve. Background Art

[0002] Simply put, an electric gate valve uses an electric actuator to control the valve, thereby realizing the opening and closing of the valve. It can be divided into two parts, the upper part is the electric actuator, and the lower part is the valve. The action torque is larger than that of an electric valve. The opening and closing action speed of the electric gate valve can be adjusted. The structure is simple and easy to maintain. During the action process, due to the buffering characteristics of the gas itself, it is not easy to be damaged by getting stuck. However, there must be an air source, and its control system is also more complex than that of an electric valve. The electric gate valve is sensitive to response, safe and reliable. Many factories with high control requirements set up compressed air stations specifically for pneumatic instrument control components. Electric ones require electricity and can control their flow.

[0003] Commonly used electric gate valves may leak a small amount of water after closing the gate during use. During long-term use, water may corrode the pipeline and the device itself. Therefore, a sealing component is required to be used at the connection to prevent water leakage from affecting the overall electronic control device. For this purpose, we propose an electric gate valve sealing component. Utility Model Content
