The plug-in valve is one of the most common valve products in the valve industry today. At present, electric and pneumatic operation methods are used more, which saves time and trouble, and does not require manual operation. For the valve, the sealing performance is still more important, so how about the sealing performance of the plug-in valve?
The sealing performance of the plug-in valve is still very good. This is also one of the reasons why the plug-in valve is popular. Let's talk about the sealing performance of the lower plug-in valve. What are the characteristics?
In order to ensure that there is no material on the sealing surface, two points need to be done. The first point is that the material cannot enter the sealing surface; The material on the surface is removed.
Because the performance of the plug-in valve is different from that of the valve used in the industrial pipeline when it is designed and used, the closure in its sealing design is to ensure that no material is placed on the sealing surface, the reason is If there is granular or powdery material on the sealing surface, it will cause the valve to be less tightly closed when it is closed, which will cause leakage. Therefore, it is necessary to ensure that there is no material on the sealing surface.
