In the design of cryogenic valves, on the one hand, the structural design ensures that the packing is close to the ambient temperature. For example, the long-neck bonnet structure is adopted to keep the stuffing box as far away from the cryogenic medium as possible. On the other hand, consideration should be given to the selection of packing Low temperature characteristics of the filler. Asbestos filler impregnated with PTFE is generally used in cryogenic valves. Flexible graphite is a newly developed excellent sealing material. Cryogenic valves can also be sealed with bellows without packing, usually multi-layer bellows. Gaskets for cryogenic valves must have reliable sealing and restorability at room temperature, low temperature and temperature changes. As the gasket material will harden and reduce plasticity at low temperatures, a gasket material with small performance changes should be selected. When the operating temperature is -200℃ and the maximum operating pressure at low temperature is 3MPa, asbestos rubber sheet made of long-fiber white asbestos is used. When the service temperature is -200℃ and the maximum working pressure is 5MPa, the spiral wound gasket made of acid-resistant steel tape and asbestos, or the spiral wound gasket made of polytetrafluoroethylene and acid-resistant steel tape. Spiral wound gaskets made of flexible graphite and acid-resistant steel are ideal for low-temperature valves at -200℃.
