Cryogenic valve design requirements
According to the conditions of use, the design of the cryogenic valve has the following requirements: 1) The valve should have the ability to work long hours under low temperature medium and ambient temperature. 2) Valves should not be a significant source of heat for cryogenic systems. This is because the inflow of heat in addition to reducing thermal efficiency, such as excessive influx, but also the rapid evaporation of the internal fluid, resulting in abnormal pressure, causing danger. 3) Low temperature media should not have a detrimental effect on handwheel handling and packing seal performance. 4) The valve assembly directly in contact with low temperature medium shall have an explosion-proof and fireproof structure. 5) The valve assembly working at low temperature can not be lubricated, so structural measures need to be taken to prevent abrasion of the friction parts.
