| description | The utility model provides an anti-misoperation gate valve, which relates to the technical field of gate valves, and comprises a valve body, the top of the valve body is fixedly connected with an upper support frame, the top of the upper support frame is rotatably connected with a rotating ring, the rotating ring is rotatably connected with a rotating disc, and the rotating disc is sleeved with a valve rod in a threaded manner. The gate valve self-locking device is reasonable in structure, by arranging the first limiting assembly and the second limiting assembly, after the gate valve is completely closed, the situation that the gate valve is not completely closed due to the fact that a person touches the rotary disc, the valve rod moves is avoided, the self-locking function is achieved, and manual misoperation is prevented; when the gate valve is opened, the pawl is shifted manually, so that the limiting hole in the pawl slides into the limiting pin, the pawl is limited through the limiting pin, the ratchet w |
