VCR fittings are a kind of face seal fittings, the sealing element adopts precision-made metal gasket with high purity metal-to-metal sealing, thus can provide leakage-free service in the range of vacuum to positive pressure. So do you know what is the working principle of VCR joints?

The working principle of VCR joint is as follows:

1, the working principle of VCR joints VCR joints is a kind of face sealing joints, sealing elements using precision manufactured metal gaskets, with high purity metal-to-metal sealing, which can provide leak-free service in the range of vacuum to positive pressure. The inner and outer threads are interlocked to enable the flanges on both sides to press against the metal gasket, so that the deformation of the gasket is produced, thus achieving the sealing effect.

2、The working principle of ferrule joint The working principle of ferrule joint is to insert the steel pipe into the ferrule, utilize the ferrule nut and the front ferrule for the main sealing, and utilize the rear ferrule's hinging-clamping action to form a strong grip on the tube. It is connected with the steel pipe without welding, which is favorable for fireproof, explosion-proof and high-altitude operation, and can remove the disadvantages brought about by inadvertent welding. Therefore, it is a more advanced connection in the pipeline of automatic control devices of oil refining, chemical, petroleum, food, pharmaceutical, instrumentation and other systems. Suitable for oil, gas, water and other media pipeline connection.

VCR coupling is a kind of face sealing coupling, the sealing element adopts precision-made metal gasket, with high purity metal-to-metal sealing, thus can provide leakage-free service in the range of vacuum to positive pressure.
