Use of valves

When gate valve is closed

The sealing surface can only rely on the medium pressure to seal, that is, rely on the medium pressure to press the sealing surface of the gate to the other side of the valve seat to ensure the sealing surface, this is self-sealing.Most gate valves are forced to seal, that is, when the valve is closed, it is necessary to rely on external force to force the gate to the valve seat to ensure the sealing surface of the sealing.

Open the door

When the gate height is equal to 1:1 of the valve diameter, the flow path is completely clear, but this position cannot be monitored during operation.In practice, the vertex of the valve stem is used as a sign, that is, the position of the open, as its full open position.In order to consider the temperature changes appear lock phenomenon, usually open to the apex position, and then back to the 12-1 turn, as the position of the full open valve.Therefore, the fully open position of the valve is determined by the position of the gate (i.e. the stroke).

Advantages of valves

1, flow rest resistance is small.

2, open and close the external force required is small.

3, the flow of the medium is not restricted.

4. When fully open, the sealing surface is smaller than the globe valve by the erosion of the working medium.5, the body is relatively simple, the casting process is better.
