Abstract

The release mechanism comprises a counter-pressure valve mounted in a vessel half-filled with extinguisher fluid and then pressurised with air or nitrogen to 14 bar. The valve comprises a spring-loaded piston, and a drop in pressure beneath the piston causes the valve to open, enabling extinguisher fluid to be released. The pressure drop beneath the piston is caused by connecting the area beneath it to a hose mounted inside the engine room, the opposite end of the hose containing a valve activated by a fire-sensitive device.

Utlösningsanordning för ett sprinklersystem, avsett att anord-d nas i ett övervakat utrymme, vilken anordning innefattar ett med mottrycksventil försett ventilhus, som är anordnat på en under tryck stående behållare med brandbekämpningsmedel, varvid mottrycksventilen innefattar en på sin undre sida fjäderbelastad kolv (2), som är anordnad i ventilhuset och satt under tryck, och som är fast förbunden med ett ventilorgan (7), vilket i ett viloläge för kolven (2), dvs då fluidtrycket plus fjädertrycket på kolvens (2) undersida är lika stort som fluidtrycket på dess översida, är avsett att tillsluta behållaren (21), och kolven är, då trycket sänks på kolvens (2) undersida, avsedd att öppna behållaren (21), vil- ket leder till att brandbekämpningsmedlet strömmar ut ur behålla- ren och in i sprinklersystemet. kännetecknad därav, att en sluten slang är anordnad mellan utrymmet på kolvens (2) undersida och det övervakade utrymmet, varvid trycket i nämnda slang faller vid I brand i det övervakade utrymmet, vilket leder till att brandbe- kämpningsmedlet strömmar ut ur behållaren och in i sprinkler- systemet.A release device for a sprinkler system, intended to be arranged in a monitored space, which device comprises a valve housing provided with a back pressure valve, which is arranged on a pressurized container with fire-extinguishing agent, the back pressure valve comprising a spring-loaded piston ( 2), which is arranged in the valve housing and is under pressure, and which is fixedly connected to a valve member (7), which in a rest position of the piston (2), i.e. when the fluid pressure plus the spring pressure on the underside of the piston (2) is equal to the fluid pressure on its upper side, is intended to close the container (21), and the piston is, when the pressure is lowered on the underside of the piston (2), intended to open the container (21), which leads to the fire-fighting agent flowing out of the container and into the sprinkler system. characterized in that a closed hose is arranged between the space on the underside of the piston (2) and the monitored space, the pressure in said hose falling on fire in the monitored space, which leads to the fire-fighting agent flowing out of the container and into sprinkler system. 2. Anordning enligt krav 1, kännetecknad därav, att i kolvens viloläge, då fluidtrycket plus fjädertrycket på kolvens undersida är lika stort som fluidtrycket på dess översida, uppnås trycket under kolven (2) genom en kanal, som är anordnad mellan be- hållaren och ventilhuset (1), och att fluidtrycket ovanför kolven (2) uppnås genom en med backventil (9) försedd, utvändig för- bindelse (8, 10) mellan ventilhuset (1) och utrymmet på kolvens (2) ovansida. LI\ALLMDATA\SVARO\KRAV\21116-krav.1402.d0CDevice according to claim 1, characterized in that in the rest position of the piston, when the fluid pressure plus the spring pressure on the underside of the piston is equal to the fluid pressure on its upper side, the pressure under the piston (2) is achieved through a channel arranged between the container and the valve housing (1), and that the fluid pressure above the piston (2) is achieved by an external connection (8, 10) provided with a non-return valve (9) between the valve housing (1) and the space on the upper side of the piston (2).
