在消防系統中，自動噴水滅火系統主要包括防爆信號蝶閥、防爆報警閥、防爆雨淋閥、不銹鋼報警閥、不銹鋼雨淋閥、活塞式雨淋閥、活塞式不銹鋼雨淋閥等。下面
川消小編就來講講相關內容吧。
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.
防爆雨淋閥裝置廣泛用于雨淋系統、預作用系統、水幕系統、水霧系統。防爆雨淋閥裝置通過保護區現場火災探測系統的控制而動作，tdaf001當保護區某處發生火災時，環境溫度升高，火災探測系統動作，聯動雨淋閥開啟，使大量水從開式噴頭中噴出，同時發出聲、光報警信號，以達到報警、控火、滅火之目的。
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.
事實上防爆報警閥屬于濕式噴淋系統，而相對應的也就存在著干式噴淋系統。那么干式噴淋系統與濕式噴淋系統的區別在于：
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:
濕式噴淋系統：準工作狀態(火災噴灑為工作狀態)時管道內充滿了有壓力的水。
Wet sprinkler system: the pipeline is full of pressurized water in the quasi working state (fire sprinkler is in the working state).
干式噴淋系統：準工作狀態時管道內充滿有壓力的氣體。
Dry spray system: when in quasi working state, the pipeline is filled with pressurized gas.
環境溫度是確定選擇濕式或干式系統的依據。4℃≤環境溫度≤70℃的場所應采用濕式系統;環境溫度<4℃或>70℃的場所應采用干式系統。
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：溫度低時，管道內的水結冰會撐裂管道;溫度過高，水發熱蒸發，所以不宜采用濕式系統，應該采用干式系統。
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.
濕式、干式系統應在開放一只噴頭后自動啟動，預作用、雨淋系統應在火災探測器動作報警時自動啟動。
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.
雨淋報警閥的工作原理和功能是可以根據火情控制樓房消防管道中的消防儲水單向朝著噴水滅火噴頭流動，是一種及時的消防閥門。一般的雨淋報警閥都設計有水力警鈴、球閥、針閥和壓力開關這些閥門部件。
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.
雨淋閥是可以在瞬間開啟，讓水涌入閥腔進入配水管網的自動閥門。
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.
雨淋閥的閥腔分為上腔、下腔和控制腔三部分。控制腔與供水管道連通，中間設限流傳壓的孔板。供水管道中的壓力水推動控制腔中的膜片，進而推動驅動桿頂緊閥瓣鎖定桿，鎖定桿產生力矩，把閥板鎖定在閥座上。閥瓣使下腔的壓力水不能進入上腔。消防時，由于控制腔泄壓，使驅動桿作用在閥瓣鎖定桿上的力矩低于供水壓力作用在閥瓣上的力矩，于是閥瓣開啟，供水進入配水管道。
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.
