Therefore, the current domestic vigorous development of hydrogen energy facilities, including upstream hydrogen production, midstream hydrogen storage and downstream hydrogen transportation, requires the support of hydrogen energy equipment. Valves are of course an important part of hydrogen energy equipment. Plug valves are a common type of valve, usually used to control the flow and direction of fluids. In the field of hydrogen energy, plug valves are usually used in hydrogen transportation and distribution systems, such as in hydrogen storage and hydrogen refueling stations. The main feature of the plug valve is that the flow and direction of the fluid can be controlled by rotating the plug, and the fluid channel can be quickly cut off or opened. Therefore, plug valves are generally considered to be a reliable and efficient valve type, suitable for applications that require frequent switching and flow adjustment.

In addition, the plug valve needs to be cleaned after being used for a period of time, but the existing plug valve cover is not easy to disassemble and install, which wastes a lot of time. Therefore, the purpose of the utility model is to provide a plug valve for hydrogen energy. Utility Model Content
