More Information
Summary:The utility model is applicable to the technical field of gate valves, and provides an anti-misoperation gate valve, a first threaded rod used for driving a valve core main body to perform lifting motion is arranged in a supporting block, a rotating rod used for driving the first threaded rod to rotate is sleeved on the first threaded rod, and a spring is arranged below a lifting block. The spring is used for separating the rotating rod from the first threaded rod, after the gate valve is rotated to be opened or closed, the hand pressing the rotating head is loosened, the rotating head does not have pressure and can rebound under the acting force of the spring, the rotating rod can be separated from the first threaded rod, and therefore even if the rotating head is touched by mistake, the rotating rod cannot drive the first threaded rod to rotate; and when the rotating rod is lifted through a spring, two threaded sleeve rods can be inserted into clamping grooves formed in the two sides of a clamping block thr
