working principle
The opening and closing part of the gate valve is a gate. The movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used gate valves form a wedge shape. The wedge angle varies with the valve parameters, usually 5 °, and 2 ° 52 'when the medium temperature is not high.
