верхняя герметичность запорных клапанов и их оптимизация
Globe valves are important fluid control devices widely used in various piping systems. Their main function is to regulate or stop the flow of fluid. The sealing performance of these globe valves directly affects their efficiency and lifespan, making the design and application of the upper sealing device particularly crucial. The upper sealing device, commonly referred to as the inverted seal, effectively prevents fluid leakage into the packing chamber while ensuring the normal operation of the...
