Product overview:
The opening and closing part of the gate valve (gate valve) is the gate plate. The direction of movement of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, not adjusted and throttled.The gate has two sealing surfaces. The most commonly used mode is that the two sealing surfaces of the gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50, and 2°52' when the medium temperature is not high.
When the valve is opened, when the lifting height of the gate is equal to 1:1 times the diameter of the valve, the passage of the fluid is completely unblocked, but during operation, this position cannot be monitored.In actual use, the apex of the stem is used as a sign, that is, the position where it cannot be opened, as its fully open position.In order to consider the locking phenomenon of temperature changes, it is usually at the position of opening to the apex, and then rewind 1/2-1 circle as the position of the fully open valve.Therefore, the fully open position of the valve is determined by the position of the gate (that is, the stroke).
