The company mainly produces low-temperature and high-pressure globe valves, can provide low-temperature and high-pressure globe valves prices, low-temperature and high-pressure globe valves manuals, low-temperature and high-pressure globe valves physical maps, low-temperature and high-pressure globe valves structural drawings, low-temperature and high-pressure globe valves dimensions, low-temperature and high-pressure globe valves implementation standards, The working principle of low temperature and high pressure stop valve, the characteristics of low temperature and high pressure stop valve.The working principle and application of low temperature and high pressure globe valve products: The opening and closing parts of the low-temperature high-pressure shut-off valve are plug-shaped flaps, the sealing surface is flat or conical, and the flaps move linearly along the center line of the fluid. The movement form of the valve stem includes a lifting rod type (the valve rod is raised and lowered, the hand wheel is not raised and lowered), and a lifting and rotating rod type (the hand wheel and the valve rod rotate and lift together, and the nut is provided on the valve body). The shut-off valve is only suitable for fully open and fully closed, and it is not allowed to adjust and throttle. Low temperature and high pressure shut-off valves are used in gas liquefaction equipment, air separation equipment; natural gas liquefaction, storage and transportation equipment; liquid oxygen, nitrogen, argon, hydrogen, carbon dioxide cryogenic storage tanks and tank trucks; pressure swing adsorption oxygen production, nitrogen equipment. Widely used in industries such as energy, petrochemical, metallurgy, aerospace, nuclear industry, railway and other industries.

In recent years, ultra-low temperature valves have become more and more widely used. 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.
