产品详情/ Product details
SF6 anti-error lock valve control tee joint (Winfoss-A21-3D) is mainly used in the power industry with SF6 gas as the arc extinguishing medium of high pressure equipment, through the operation of the online detection valve knob, to achieve the valve and the equipment body gas path open and shut. Thus, the charging and replenishment of equipment body and the on-line calibration and replacement of SF6 density relay controller are realized. The product is equipped with anti-error mechanical lock to prevent the operation of the equipment during operation, to ensure the safety and reliability of the equipment operation.
SF6 Anti-mislock valve control tee (Winfoss-A21-3D)
Do not disassemble online verification test, prevent mislock machinery, can be pairedAll kinds of switch interfaces at home and abroad, worry free, safe and reliable!
summarize
SF6 anti-error lock valve control tee joint (Winfoss-A21-3D) is mainly used in the power industry with SF6 gas as the arc extinguishing medium of high pressure equipment, through the operation of the online detection valve knob, to achieve the valve and the equipment body gas path open and shut. Thus, the charging and replenishment of equipment body and the on-line calibration and replacement of SF6 density relay controller are realized. The product is equipped with anti-error mechanical lock to prevent the operation of the equipment during operation, to ensure the safety and reliability of the equipment operation.
According to the "National Energy Administration on the prevention of power production accidents 25 key requirements" (National energy safety2014:161 No13.1.6The connection between the sulfur hexafluoride density relay and the switchgear body shall meet the requirements of not disassembling the check density relay.
Apply
SF6 anti-error lock valve control tee connector is mainly suitable for the power industry to achieve the requirements of online detection and verification of density relays without disassembly, and is equipped with anti-error lock mechanical device to prevent the equipment from being misoperated during operation.
