Working principle
The gate plate of the gate valve moves linearly with the valve stem The lift rod gate valve often has a trapezoidal thread on the lift rod. Through the nut on the top of the valve and the guide groove on the valve body, the rotational motion is changed into linear motion, that is, the operating torque is changed into the operating thrust. The sealing surface can be sealed only by the medium pressure, that is, by relying on the medium pressure to press the sealing surface of the gate plate to the valve seat on the other side to ensure the sealing surface sealing, this is self-sealing.
Most gate valves adopt forced sealing, that is, when the valve is closed, external force must be relied on to force the gate plate to the valve seat to ensure the sealing performance of the sealing surface
