1、湿式报警阀。湿式报警阀是湿式自动喷水灭火系统的主要部件，安装在总供水干管上，连接供水设备和配水管网，是一种只允许水流单方向流人配水管网，并在规定流量下报警的止回型阀门，在系统动作前，它将管网与水流隔开，避免用水和可能的污染;当系统开启时，报警阀打开，接通水源和配水管;在报警阀开启的同时，部分水流通过阀座上的环形槽，经信号管道送水力警铃，发出音响报警信号。

1. Wet alarm valve. The wet alarm valve is the main component of the wet automatic sprinkler system, installed on the main water supply pipe, connecting the water supply equipment and the water distribution network. It is a check valve that only allows water flow to flow in one direction into the water distribution network and alarms at the specified flow rate. Before the system operates, it separates the network from the water flow to avoid water use and possible pollution; When the system is turned on, the alarm valve opens, connecting the water source and distribution pipe; At the same time as the alarm valve is opened, some water flows through the circular groove on the valve seat and is sent to the hydraulic alarm bell through the signal pipeline, emitting an audible alarm signal.

2、干式报警阀。川消干式报警阀主要用在干式自动喷水灭火系统和干湿式自动喷水灭火系统中。其作用是用来隔开喷水管网中的空气和供水管道中的压力水，使喷水管网始终保持干管状态，当喷头开启时，管网空气压力下降，干式阀阀瓣开启，水通过报警阀进人喷水管网，同时部分水流通过报警阀的环形槽进人信号设施进行报警。干式报警阀由阀体、差动双盘阀板、充气塞、信号管网、控制阀等组成。

2. Dry alarm valve. Chuanxiao dry alarm valve is mainly used in dry automatic sprinkler systems and dry wet automatic sprinkler systems. Its function is to separate the air in the water spraying network from the pressure water in the water supply pipeline, so that the water spraying network remains in a dry pipe state. When the nozzle is opened, the air pressure in the network decreases, the dry valve disc opens, and water enters the water spraying network through the alarm valve. At the same time, some water flows through the circular groove of the alarm valve and enters the signal facility for alarm. The dry alarm valve consists of a valve body, differential double disc valve plate, inflation plug, signal pipeline network, control valve, etc.

3、雨淋报警阀。雨淋阀用于雨淋喷水灭火系统、预作用喷水灭火系统、水幕系统和水喷雾灭火系统。这种阀的进口侧与水源相连，出口侧与系统管路和喷头相连。一般为空管，仅在预作用系统中充气。

3. Deluge alarm valve. Deluge valve is used for deluge sprinkler system, pre action sprinkler system, water curtain system and water spray extinguishing system. The inlet side of this valve is connected to the water source, and the outlet side is connected to the system pipeline and nozzle. Generally, it is an empty tube and only inflated in the pre action system.

从以上可以看出，川消报警阀有着复杂而有效的工作原理，它能够在雨淋时发出报警信号，提醒人们外出时要注意自身和保护室外环境，从而有效的防止火灾和危险情况的发生，也起到了重要的社会保护作用。更多相关事项就来我们网站http://www.cx-fire.com咨询！
