Analysis of sealing performance of cemented carbide valve seat

Cemented carbide valve seat plays a vital role in the field of valves, and its sealing performance directly affects the use of valves and safety. In this paper, the sealing performance of cemented carbide valve seat will be analysed in depth, and its sealing mechanism, advantages and application areas will be discussed.

The sealing performance of valve seat mainly depends on the following aspects. Surface hardness: Cemented carbide has very high hardness, which can effectively resist the impact and abrasion of external media and maintain the flatness of its surface and sealing performance. Surface finish: Cemented carbide valve seat is processed and polished precisely, with high surface finish, which can reduce the possibility of leakage when sealing and improve the sealing effect. Material formula: the formula of the cemented carbide material is carefully designed to maintain stable sealing performance in different working environments, with good abrasion resistance and corrosion resistance. Structural design: The structure of the carbide valve seat is reasonably designed to ensure the matching precision between the seal and the valve body, reduce the leakage channel and improve the sealing effect.

Cemented carbide valve seats are widely used in various industrial fields due to their excellent sealing performance and multifaceted advantages. The excellent performance of its sealing performance makes the carbide valve seat become an indispensable and important part of the valve field, providing a reliable guarantee for the safe and efficient operation of industrial production.
