1、濕式報警閥。濕式報警閥是濕式自動噴水滅火系統的主要部件，安裝在總供水干管上，連接供水設備和配水管網，是一種只允許水流單方向流人配水管網，并在規定流量下報警的止回型閥門，在系統動作前，它將管網與水流隔開，避免用水和可能的污染;當系統開啟時，報警閥打開，接通水源和配水管;在報警閥開啟的同時，部分水流通過閥座上的環形槽，經信號管道送水力警鈴，發出音響報警信號。

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、干式報警閥。川消干式報警閥主要用在干式自動噴水滅火系統和干濕式自動噴水滅火系統中。其作用是用來隔開噴水管網中的空氣和供水管道中的壓力水，使噴水管網始終保持干管狀態，當噴頭開啟時，管網空氣壓力下降，干式閥閥瓣開啟，水通過報警閥進人噴水管網，同時部分水流通過報警閥的環形槽進人信號設施進行報警。干式報警閥由閥體、差動雙盤閥板、充氣塞、信號管網、控制閥等組成。

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、雨淋報警閥。雨淋閥用于雨淋噴水滅火系統、預作用噴水滅火系統、水幕系統和水噴霧滅火系統。這種閥的進口側與水源相連，出口側與系統管路和噴頭相連。一般為空管，僅在預作用系統中充氣。

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.

從以上可以看出，川消報警閥有著復雜而有效的工作原理，它能夠在雨淋時發出報警信號，提醒人們外出時要注意自身和保護室外環境，從而有效的防止火災和危險情況的發生，也起到了重要的社會保護作用。更多相關事項就來我們網站http://www.xintli.net咨詢！

From the above, it can be seen that the Chuanxiao alarm valve has a complex and effective working principle. It can send out an alarm signal in case of rain, reminding people to pay attention to their own safety and protect the outdoor environment when going out, effectively preventing fires and dangerous situations, and also playing a crucial social protection role.
