I. Product overview WINFOSS-A21-3I series SF6 density relay calibration three-way valve is mainly used in the power industry with SF6 gas as the arc extinguishing medium of high pressure equipment, through the operation of the handle knob on the three-way valve, to achieve the three-way valve and the equipment body gas path, off. Thus, the equipment body is charged, replenishment air and SF6 density controller online calibration, testing and replacement work is realized.

The critical temperature is the high temperature at which sulfur hexafluoride gas liquefaction occurs. The critical pressure indicates the gas pressure required for liquefaction to occur at this temperature. Sulfur hexafluoride can only remain gaseous when the temperature is above 45 degrees, under normal conditions of use, it has the possibility of liquefaction, so sulfur hexafluoride can not be used at low temperatures and too low pressure.

Sulfur hexafluoride, molecular formula SF6, relative molecular weight is 146.06, at normal temperature and pressure for colorless, tasteless, non-toxic, non-corrosive, non-flammable, non-explosive gas, density of about 5 times the air, the standard state density of 6.0886kg cubic meters. It is liquid at low temperature and under pressure and becomes a white solid when frozen. The sublimation temperature is -63.9℃, the melting point is -50.8℃, the critical temperature is 45.55℃, and the critical
