What is the function of gate valve?

The main function of gate valve is to cut off or cut off the fluid medium, that is, to control the opening or closing of the fluid. It changes the diameter of the flow channel through the lifting of the gate, so as to realize the circulation or blocking of the fluid.

Gate valves are usually used in the following situations:

1. Cut off the fluid circulation: When it is necessary to completely cut off the fluid circulation, the gate valve can completely cut off the flow passage by raising the gate to the fully closed position, thus achieving the purpose of cutting off the fluid circulation.

2. Open the fluid circulation: When the fluid needs to circulate freely, the gate valve can completely open the flow passage by lowering the gate to the fully open position, thus realizing the opening of the fluid.

3. Fluid flow direction control: The gate valve can adjust the flow direction of the fluid through the lifting of the gate, thus controlling the flow direction of the fluid in the pipeline.

4. Fluid flow control: Although the gate valve is not suitable for accurate flow adjustment, in some applications, the gate valve can achieve a certain degree of flow control by controlling the lift of the gate.

It should be noted that the gate valve is not suitable for frequent opening and closing operations, because the lifting of the gate requires a certain operating force and is suitable for relatively stable fluid circulation control. When selecting gate valves, we should comprehensively consider their characteristics and limitations according to the specific process requirements and application occasions to ensure the selection of appropriate valve types.
