YYXYK-A1-type pressure relief openings

Shanghai million tracks Electrical Technology Co. specializes in producing pressure relief openings, specifically the following models: FXYJ-1 Mechanical type pressure relief openings, FXYJ-2 mechanical type pressure relief openings, FXYJ-3 mechanical type pressure relief openings FXY-II electric type vent pressure valve, FXY-III electric type pressure relief valve, FXY-IV machine electric type pressure relief valve XYK-A pressure relief openings, XYK-B pressure relief openings, SAXD-0.25-J mechanical type pressure relief openings, SAXD-0.12- J Mechanical type pressure relief openings SAXD-0.1 electric type pressure relief valve, SAXD-0.15 electric type pressure relief valve, SAXD-0.25 electric type pressure relief valve vent valve TKC, TKC vent port, YYXYK-B1-type pressure relief openings, YYXYK-A1-type pressure relief openings, YYXYK-A2 type relief relief port is mounted on the wall and / or ceiling fire protection district, the gas fire extinguishing system is an integral part, usually in the closed state. When the gas fire extinguishing system on the implementation of fire protection district, will produce more than the protected area building permit pressure, this time, automatic pressure relief vent opening super-pressure portion of the protected areas in the implementation of protection; when the pressure is reduced, closed pressure relief port, to ensure airtight protection zone to meet the needs of the fire. Its name: the protection zone gas fire extinguishing system pressure relief opening (automatic pressure relief device). For the outdoor installation, when the pressure reaches a certain value, no power pressure relief port starts automatically open, effective relief area of ??0.15m2, enabling the operating pressure of 1.1 + 0.1KPa. Another name is: no power outdoor wall cover integrated pressure relief opening (automatic pressure relief device).
