　           报警阀是自动喷水灭火系统中接通或切断水源，并启动报警器的装置。 在自动喷水灭火系统中，报警阀是至关重要的组件，其作用有三：接通或切断水源、输出报警信号和 防止水流倒回供水源，过滤器以及通过报警阀可以对系统的供水装置和报警装置进行检验。 报警阀根据系统的不同分为湿式报警阀、鸭嘴阀干式报警阀和雨淋阀。

 1.湿式报警阀用于湿式喷水灭火系统。排气阀、排泥阀 它的主要功能是：当喷头开启时，湿式阀能自动打开，并使 水流入水力警铃发出报警信号。

 2.干式报警阀用于干式喷水灭火系统。它的阀瓣将阀门分成两部分，出口侧与系统管路和喷头相连，内充压缩空气，进口侧与水源 相连。低温阀门干式阀利用两侧气压和水压作用在阀瓣上的力矩差控制阀瓣的封闭和开启，一般可分为差动型干式报警阀和封闭型干式报警阀两种。

 3.雨淋阀用于雨淋喷水灭火系统、预作用喷水灭火系统、水力控制阀水幕系统和水喷雾灭系统。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。雨淋阀的开启由各种火灾探测装置控制。

           Sprinkler alarm valve is connected to the system or shut off the water, and start the alarm device. In the automatic sprinkler system, the alarm valve is critical component, its role has three: turn on or shut off the water, Split case pumps the output alarm signal and to prevent the flow back into the water supply source, and through the alarm valve to the water supply device and the system alarm device test. According to the system alarm valvesVacuum pumps were divided into wet alarm valve, dry pipe valves and deluge valve. 1. Wet alarm valve for wet sprinkler system. Its main function is: When the nozzle is open, wet valve automatically opens, Oil pumpsand make water flow into the water alarm alarm signal. 2. Dry alarm valves for dry sprinkler system. It will be the valve disc is divided into two parts, the export side is connected with the system piping and nozzles, compressed air within the full In-line pumpsimport side and water connected. Dry air pressure and water pressure valve function using both sides of the valve flap flap torque difference control valve closed and open, generally can be divided into differential-type dry pipe valves and two closed dry alarm valve. 3. Rain for the rain and sprinkler system valve, pre-action sprinkler system, water curtain and water spray offfire pumps the system. The import side of this valve is connected with the water and exit side of the system piping and nozzles attached, usually empty tube, only the role of the system in pre-inflated. Rain to open the valve controlled by a variety of fire detection devices.
