summarize

SF6 density relay three-way valve device (Winfoss-A21-3I) is mainly used in the power industry with SF6 gas as the arc extinguishing medium of high pressure equipment, through the operation of the on-line detection valve knob, to realize the valve and the equipment body gas path. Thus, the aeration, aeration and micro-water, decomposition, purity test of the cavity in the body of the equipment and the on-line calibration and replacement of SF6 density relay controller are realized. According to Article 13.1.6 of the "25 Key Requirements of the National Energy Administration on Preventing power Production Accidents" (National Energy Safety (2014) No. 161), the connection between the sulfur hexafluoride density relay and the switchgear body should meet the requirements of not disassembling the check density relay.
