The cryogenic valve is one of indispensable equipment in such industries as petochemical industry, coal chemical industry, air separation, natural gas, tobacco, etc. Its performance and reliability have a direct impact on the safe and economic operation of all the industrial whole-set equipment. Except liquid nitrogen and liguid inert gas, most of the media controlled by the cryogenic valve are inflammable, explosive and permeable. Its minimum working pressure is 10MPa. Such severe service conditions have brought forward special requirements for the cryogenci valve, which is different from ordinary valves in its design, manufacturing and inspection. Under cryogenci service conditions, the valve is required to conquer three dangerous factors, i. E. Abnormal prssure rise caused by rapid vaporization of cryogenci media remaining in the cavity duting the opening and closing of the valve because of ambient(atmospheric) temperature: Cryogenic transfer towards the packing box that leads to the failure of the packing and causes leakage at the packing box; Theability of pressure parts to resist cryogenic impact.
