Low-temperature stainless steel globe valve design standards, according to the conditions of use, the design of low-temperature stainless steel globe valve has the following requirements: 1, the valve in the low temperature medium and ambient temperature should have a long working capacity. 2, the valve should not become a significant source of low-temperature system. 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 medium should not be hand wheel operation and packing sealing performance have a detrimental effect. 4, the valve assembly directly in contact with low temperature medium should have explosion-proof and fireproof structure.
5, the valve assembly working at low temperatures can not be lubricated, so the need to take structural measures to prevent abrasion friction parts.
