湿式自动灭火系统由闭式玻璃球喷头、报警止回阀、延迟器、水力警铃及给水管网组成,如果配上压力开关,水流指示器,电磁阀及电控箱等即可组成更为完善的系统。这个系统平时充满具有一定压力的水。在无火警情况下,只需恒压水源,维持较低压力(保证最远点喷头1 kg/cm~2压力)即可。当保护区内某处发生火灾,着火部位环境温度升高到一定温度时,玻璃球炸裂,喷口自动开启,开始喷水灭火。
Wet automatic fire extinguishing system consists of closed glass ball nozzle, alarm check valve, delay device, hydraulic alarm and water supply network, if coupled with pressure switch, water flow indicator, solenoid valve and electric control box can be more perfect system. This system is usually full of water with some pressure. In case of no fire, just constant pressure water source, to maintain a low pressure (to ensure the furthest point nozzle 1 kg / cm ~ 2 pressure) can be. When a fire broke out somewhere in the protected area and the ambient temperature of the ignition part rose to a certain temperature, the glass ball exploded and the spout automatically opened to begin sprinkler fire.
