Common Sense Of Fall Lift Safety Valve

In recent years, ultra-low temperature valves have become more and more widely used, and they are one of the indispensable important equipment in petrochemical, air separation, natural gas and other industries. The working medium is not only low in temperature, but most of them are toxic, or flammable and explosive. , And strong permeability, so it determines many special requirements for valve materials and design. It is not only required to work normally at the set temperature, but also to ensure the working performance at room temperature.

Compared with normal temperature valves, cryogenic valves have higher packing parts and use extended stems. Its purpose is to reduce the heat introduced into the device from the outside; to ensure that the temperature of the stuffing box is above 0°C, so that the packing can work normally; to prevent the valve stem and valve cover in the stuffing box from being too cold due to the part of the stuffing box The upper parts are frosted or frozen.
