The gate of the open gate valve moves linearly with the valve stem. Usually, there is a trapezoidal thread on the lifting rod. Through the top of the valve (the nut of the end and the guide groove on the valve body, the rotary motion is changed into a linear motion, that is, the operation is turned The moment becomes the operating thrust. Turning the handwheel, through the advancement and retreat of the thread of the handwheel and the stem, raises or lowers the valve plate linked with the valve stem to achieve the purpose of opening and closing. The opening and closing member of the open gate valve is a gate. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted and throttled.
