在消防系统中，自动喷水灭火系统主要包括防爆信号蝶阀、防爆报警阀、防爆雨淋阀、不锈钢报警阀、不锈钢雨淋阀、活塞式雨淋阀、活塞式不锈钢雨淋阀等。下面
川消小编就来讲讲相关内容吧。
In the fire protection system, the automatic sprinkler system mainly includes explosion-proof signal butterfly valve, explosion-proof alarm valve, explosion-proof deluge valve, stainless steel alarm valve, stainless steel deluge valve, piston deluge valve, piston stainless steel deluge valve, etc. Now let's talk about the relevant content.
防爆雨淋阀装置广泛用于雨淋系统、预作用系统、水幕系统、水雾系统。防爆雨淋阀装置通过保护区现场火灾探测系统的控制而动作，tdaf001当保护区某处发生火灾时，环境温度升高，火灾探测系统动作，联动雨淋阀开启，使大量水从开式喷头中喷出，同时发出声、光报警信号，以达到报警、控火、灭火之目的。
Explosion proof deluge valve device is widely used in deluge system, pre action system, water curtain system and water mist system. The explosion-proof deluge valve device acts through the control of the on-site fire detection system in the protection area. Tdaf001 when a fire occurs in the protection area, the ambient temperature rises, the fire detection system acts, and the linkage deluge valve is opened, so that a large amount of water is ejected from the open sprinkler, and acoustic and optical alarm signals are sent at the same time, so as to achieve the purpose of alarm, fire control and fire extinguishing.
事实上防爆报警阀属于湿式喷淋系统，而相对应的也就存在着干式喷淋系统。那么干式喷淋系统与湿式喷淋系统的区别在于：
In fact, the explosion-proof alarm valve belongs to the wet sprinkler system, and the corresponding dry sprinkler system exists. Then the difference between dry sprinkler system and wet sprinkler system is:
湿式喷淋系统：准工作状态(火灾喷洒为工作状态)时管道内充满了有压力的水。
Wet sprinkler system: the pipeline is full of pressurized water in the quasi working state (fire sprinkler is in the working state).
干式喷淋系统：准工作状态时管道内充满有压力的气体。
Dry spray system: when in quasi working state, the pipeline is filled with pressurized gas.
环境温度是确定选择湿式或干式系统的依据。4℃≤环境温度≤70℃的场所应采用湿式系统;环境温度<4℃或>70℃的场所应采用干式系统。
The ambient temperature is the basis for selecting wet or dry system. Wet system shall be adopted in places with 4 ℃ ≤ ambient temperature ≤ 70 ℃; Dry system shall be used in places with ambient temperature <4 ℃ or >70 ℃.
原理：温度低时，管道内的水结冰会撑裂管道;温度过高，水发热蒸发，所以不宜采用湿式系统，应该采用干式系统。
Principle: when the temperature is low, the water in the pipe will freeze and crack the pipe; The temperature is too high, and the water is heated and evaporated, so the wet system should not be used, and the dry system should be used.
湿式、干式系统应在开放一只喷头后自动启动，预作用、雨淋系统应在火灾探测器动作报警时自动启动。
The wet and dry systems shall start automatically after opening a nozzle, and the pre action and deluge systems shall start automatically when the fire detector acts and alarms.
雨淋报警阀的工作原理和功能是可以根据火情控制楼房消防管道中的消防储水单向朝着喷水灭火喷头流动，是一种及时的消防阀门。一般的雨淋报警阀都设计有水力警铃、球阀、针阀和压力开关这些阀门部件。
The working principle and function of the deluge alarm valve is to control the one-way flow of the fire storage water in the fire pipeline of the building towards the sprinkler head according to the fire situation. It is a timely and efficient fire valve. General deluge alarm valves are designed with hydraulic alarm bells, ball valves, needle valves and pressure switches.
雨淋阀是可以在瞬间开启，让水涌入阀腔进入配水管网的自动阀门。
Deluge valve is an automatic valve that can be opened in an instant to let water flow into the valve chamber and into the water distribution network.
雨淋阀的阀腔分为上腔、下腔和控制腔三部分。控制腔与供水管道连通，中间设限流传压的孔板。供水管道中的压力水推动控制腔中的膜片，进而推动驱动杆顶紧阀瓣锁定杆，锁定杆产生力矩，把阀板锁定在阀座上。阀瓣使下腔的压力水不能进入上腔。消防时，由于控制腔泄压，使驱动杆作用在阀瓣锁定杆上的力矩低于供水压力作用在阀瓣上的力矩，于是阀瓣开启，供水进入配水管道。
The valve chamber of deluge valve is divided into three parts: upper chamber, lower chamber and control chamber. The control chamber is connected with the water supply pipe, and an orifice plate is set in the middle to limit the pressure. The pressure water in the water supply pipe pushes the diaphragm in the control chamber, and then pushes the driving rod to tighten the disc locking rod. The locking rod generates torque to lock the valve plate on the valve seat. The valve disc prevents the pressure water in the lower chamber from entering the upper chamber. During fire fighting, due to the pressure relief of the control chamber, the torque of the driving rod acting on the disc locking rod is lower than the torque of the water supply pressure acting on the disc, so the disc is opened and the water supply enters the water distribution pipeline.
