Exploring the sealing performance of plug-in valves

In the field of valves,slide gate valveHighly praised for its excellent sealing ability. This type of valve is widely used in industrial pipeline systems, with the design goal of ensuring that there is no material residue on the sealing surface, thereby effectively preventing leakage.

1. No residual design

One of the main design features of the plug-in valve is to ensure that there is no material residue on the sealing surface. When the valve is closed, the operator needs to ensure that there is no material residue on the sealing surface, which is the key to maintaining sealing performance. This design cleverly avoids the accumulation of particles or powder on the sealing surface, reducing sealing defects and potential leakage risks during closure.

2. Selection of sealing materials

The sealing materials of plug-in valves are divided into two categories: soft seals and hard seals. Soft seals often use flexible materials such as rubber, which are suitable for applications with low temperature and pressure. And hard seals are made of metal materials, which can withstand higher temperatures and pressures. The correct selection of sealing materials is crucial for the overall performance of valves.

3. Automatic adjustment mechanism

In order to enhance sealing performance and extend service life, some plug-in valves are equipped with movable sealing seats. This design not only has anti-wear properties, but also automatically adjusts the sealing pressure to adapt to the wear of the sealing surface.

4. Easy to maintain

The structure of the plug-in valve is simple, making it easy to maintain and replace sealing components. Regular inspection and replacement of seals, as well as keeping the sealing surface clean during operation, are important measures to ensure good sealing performance.
