[Abstract] This article is Edsen's explanation of the principle and structure of gate valves
Principle of gate valve
1. Gate valves are mainly used to connect or cut off the media in the pipeline. They are widely used in various pipeline systems to control the pressure and flow of fluids, but are not suitable for adjusting the flow of media;
2. The medium channel inside the valve body is straight, and the medium flows in a straight line, with small flow resistance;
3. It is more labor-saving when opening and closing, which is compared with the stop valve, because whether it is opened or closed, the movement direction of the gate is perpendicular to the flow direction of the medium;
4. The height is large and the opening and closing time is long. The opening and closing stroke of the gate is large, and the lifting and lowering are carried out through the valve stem;
5. Due to the usually long closing time, water hammer is not easy to occur.
