報警閥安裝在自動噴水滅火系統的主水管上，裝有濕式報警閥，用于連接供水設備和配水管網。一般采用止回閥（只允許一個方向的水流流入噴水管網），防止管網中的水倒流回水池。當頭部噴水破壞閥門的壓力平衡時，閥板打開，給配水管網供水。它是一種單向閥，其出口側充滿壓縮氣體，當氣壓低于一定值時，可使水自動流入噴水系統并報警。
The alarm valve is installed on the main water pipe of the automatic sprinkler system and is equipped with a wet alarm valve to connect the water supply equipment and the water distribution network. Generally, check valves (only one direction of water flow is allowed to flow into the sprinkler pipe network) are used to prevent the water in the pipe network from flowing back to the pool. When the head spray water destroys the pressure balance of the valve, the valve plate is opened to supply water to the water distribution network. It is a one-way valve. Its outlet side is full of compressed gas. When the air pressure is lower than a certain value, the water can automatically flow into the sprinkler system and give an alarm.
(1)自動噴水滅火系統應配備報警閥組。保護室內鋼屋架和其他建筑構件的封閉系統應設置獨立的報警閥組。水幕系統應配備獨立的報警閥組或感溫雨淋閥。
(1) The sprinkler system shall be equipped with an alarm valve block. The closed system protecting indoor steel roof truss and other building components shall be provided with independent alarm valve groups. The water curtain system shall be equipped with independent alarm valve group or temperature sensing deluge valve.
(2)與濕式系統配水總管串聯的其他自動噴水系統，應分別設置獨立的報警閥組，其控制的噴水器數量應計入由其控制的噴水器總數中。濕閥組。
(2) Other automatic sprinkler systems connected in series with the water distribution header of the wet system shall be provided with independent alarm valve groups, and the number of sprinklers controlled by them shall be included in the total number of sprinklers controlled by them. Wet manifold.
(3)
川消小編認為報警閥組控制的噴嘴數量應符合下列要求：
(3) Sichuan Xiaobian believes that the number of nozzles controlled by the alarm valve group should meet the following requirements:
濕式系統和預作用系統不應超過800；干式系統不應超過500。
Wet system and pre action system shall not exceed 800; Dry systems shall not exceed 500.
配水支管安裝灑水器保護吊頂上下空間時，報警閥組控制的灑水器總數應僅計入數量較大一側的灑水器。
When sprinkler is installed on the water distribution branch pipe to protect the upper and lower space of the ceiling, the total number of sprinklers controlled by the alarm valve group shall only be included in the sprinklers on the side with a larger number.
(4)各報警閥組供水的高低位噴嘴高度差不應大于50m。
(4) The height difference between high and low nozzles for water supply of each alarm valve group shall not be greater than 50m.
(5)雨淋閥組的電磁閥入口處應有過濾器。對于雨淋閥組并聯布置的雨淋系統，雨淋閥控制室的入口應設置止回閥。
(5) There shall be a filter at the inlet of the solenoid valve of the deluge valve group. For the deluge system with deluge valve groups arranged in parallel, the inlet of the deluge valve control room shall be provided with a check valve.
(6)報警閥組應設在、便于操作的位置，報警閥離地高度應為1.2m。安裝報警閥的部位應設置排水設施。
(6) The alarm valve group shall be set at a safe and easy to operate position, and the height of the alarm valve from the ground shall be 1.2m. Drainage facilities shall be set at the position where the alarm valve is installed.
(7)連接報警閥進出口的控制閥應為信號閥。不使用信號閥時，控制閥應設有鎖緊閥位。
(7) The control valve connecting the inlet and outlet of alarm valve shall be signal valve. When the signal valve is not used, the control valve shall be provided with a locking valve position.
(8)液壓警鈴的工作壓力不應小于0.05MPa，并應滿足下列要求：
(8) The working pressure of the hydraulic alarm bell shall not be less than 0.05Mpa and shall meet the following requirements:
應位于有人值守地點附近。
It shall be located near the attended place.
與報警閥連接的管道直徑應為20mm，總長不應大于20m。
The diameter of the pipeline connected with the alarm valve shall be 20mm, and the total length shall not be greater than 20m.
