What factors affect the sealing performance of gate valves?

The sealing performance of the gate valve is affected by many factors, mainly including the following aspects:

1. Material selection: the sealing performance of the gate valve is closely related to the choice of materials. The performance of the sealing material directly affects the sealing performance of the sealing interface, the selection of high-quality, wear-resistant, corrosion-resistant materials can improve the sealing performance.

2. Design structure: different gate valve structure has different effects on sealing performance. Such as the number of sealing surfaces, sealing surface shape, sealing surface pressure and other factors will affect the sealing performance.

3. Processing accuracy: the sealing performance of the gate valve is closely related to the processing accuracy. The higher the processing precision, the higher the flatness and finish of the sealing surface, and thus the sealing performance will be better.

4. use conditions: gate valve in different conditions of use, its sealing performance will also change. Such as high temperature, high pressure, corrosive media and other harsh environments, the sealing performance of the gate valve will be affected.

5. operation mode: operation mode on the sealing performance of the gate valve also has a certain impact. Correct operation can reduce the wear and tear of the sealing surface, improve the sealing performance; while the wrong operation may cause wear and tear of the sealing surface, reduce the sealing performance.

In general, the sealing performance of the gate valve is affected by a variety of factors, only in these areas are doing a good job, in order to ensure that the sealing performance of the gate valve to achieve the best state.
