自动喷水灭火系统报警阀组一般分为：湿式报警阀组、干式报警阀组、雨淋报警阀组、预作用装置。下面川消小编为您解说更为详细的内容。

Alarm valve group of sprinkler system is generally divided into wet alarm valve group, dry alarm valve group, deluge alarm valve group and pre action device. The following is a more detailed explanation by Chuanxiao.

湿式报警阀组

Wet alarm valve group

使用于高于4℃和低于70℃的环境

Used in environments above 4 ℃ and below 70 ℃

识别：报警阀呈长方形，有延迟器的系统。

Identification: The alarm valve is rectangular and has a retarder.

组件：水流指示器，水力警铃，延迟器，湿式报警阀，压力开关，总控阀

Components: water flow indicator, hydraulic alarm bell, delayer, wet alarm valve, pressure switch, master control valve

干式报警阀组

Dry alarm valve group

使用于低于4℃和高于70℃的环境

Used in environments below 4 ℃ and above 70 ℃

识别：报警阀瓣比较宽呈大肚子形状，有充气管道，无电磁阀，有防复位装置

Identification: the alarm valve flap is relatively wide and in the shape of a large belly, with an inflation pipeline, no solenoid valve, and an anti reset device

组件：水流指示器 压力开关 水力警铃 干式报警阀 总控阀

Component: water flow indicator, pressure switch, hydraulic alarm bell, dry alarm valve, main control valve

预作用装置

Pre action device

使用于严禁管道漏水，严禁系统误喷的忌水场所

It is used in places where water leakage is strictly prohibited and system mistakenly spraying is strictly prohibited

识别：湿式和干式系统二合一系统，有2个报警阀，有充气管道，有电磁阀

Identification: Two in one wet and dry systems, with two alarm valves, air charging pipes and solenoid valves

组件：水流指示器，水力警铃（后）压力开关，湿式报警阀，雨淋报警阀，总控阀，电磁阀

Components: water flow indicator, hydraulic alarm bell (rear) pressure switch, wet alarm valve, deluge alarm valve, master control valve, solenoid valve

雨淋报警阀组

Deluge alarm valve group

适用于需大面积喷水、快速扑灭火灾的特别危险场所

It is applicable to special dangerous places where large area of water spraying and rapid fire extinguishing are required

识别：报警阀呈大圆盘，无充气管道，有电磁阀，开式喷头无末端试水装置

Identification: the alarm valve is a large disc, without air charging pipe, with solenoid valve, and the open sprinkler has no end water testing device

组件：水流指示器，压力开关（红黑），水力警铃，电磁阀，雨淋报警阀，总控阀

Components: water flow indicator, pressure switch (red and black), hydraulic alarm bell, solenoid valve, deluge alarm valve, master control valve
