1、电磁阀。收到保护区域内两个感温探测器报警信号后，由报警控制器或者消防联动控制器联动开启。开启后排掉控制腔（也称为第三腔室）的水，供水侧的有压水进入系统侧实施灭火。规范要求用专用线路连接至消防控制室的手动控制盘上。其开启的动作信号要反馈至火灾报警控制器或者消防联动控制器。
1. Electromagnetic valve. After receiving alarm signals from two temperature detectors within the protected area, the alarm controller or fire linkage controller will activate them in conjunction. Open the water in the rear control chamber (also known as the third chamber), and pressurized water from the supply side enters the system side to extinguish the fire. The specification requires a dedicated line to be connected to the manual control panel in the fire control room. The activation signal should be fed back to the fire alarm controller or fire linkage controller.
2、手动快开阀。平时常闭，在电磁阀失效的情况下可手动开启雨淋阀。为了防止误操作，可设置在手动快开盒中，发生火灾时应能安全开启和便于操作。
2. Manual quick opening valve. Normally closed, the rain shower valve can be manually opened in case of solenoid valve failure. To prevent accidental operation, it can be set in a manual quick opening box, which should be safe to open and easy to operate in case of fire.
3、传动管预留口。在不适宜电动开启的场所需要设置传动管，分为液动传动管和气动传动管。液动传动管的安装要符合湿式系统的有关要求。
3. Reserved port for transmission pipe. In places where electric opening is not suitable, transmission pipes need to be installed, which are divided into hydraulic transmission pipes and pneumatic transmission pipes. The installation of hydraulic transmission pipes should comply with the relevant requirements of wet systems.
4、防复位装置。电动阀或手动快开阀动作后，会有水流出，防止控制腔自动复位。
4. Anti reset device. After the electric valve or manual quick opening valve is activated, water will flow out to prevent the control chamber from automatically resetting.
5、复位阀。平时常闭，灭火后或者测试后打开，用于复位雨淋阀。如果常开的话有可能导致雨淋阀不能开启或者控制腔自动复位。
5. Reset valve. Normally closed, open after extinguishing or testing, used to reset the rain shower valve. If it is normally open, it may cause the rain shower valve to fail to open or the control chamber to automatically reset.
6、过滤器。电磁阀入口前和压力开关入口前各有一个。
6. Filter. There is one before the inlet of the solenoid valve and one before the inlet of the pressure switch.
7、单向阀。并联设置雨淋报警阀组的雨淋系统，其雨淋报警阀控制腔的入口应设止回阀。
7. One way valve. The rainwater system with parallel rainwater alarm valve group should have a check valve at the inlet of the rainwater alarm valve control chamber.
8、供水侧压力表、控制腔压力表。分别显示供水侧和第三腔室压力，原则上两个压力值相等。控制腔压力表在图中标为隔膜腔压力表。
8. Water supply side pressure gauge, control chamber pressure gauge. Display the pressure of the water supply side and the third chamber separately, with the principle that the two pressure values are equal. The control chamber pressure gauge is marked as a diaphragm chamber pressure gauge in the diagram.
9、试铃阀。安装在连接供水侧和报警管路的管路上，平时常闭，用于测试报警管路是否通畅、压力开关和水力警铃能否正常动作。关闭不严，有可能导致压力开关或者水力警铃误动作。
9. Test bell valve. Installed on the pipeline connecting the water supply side and the alarm pipeline, normally closed, used to test whether the alarm pipeline is unobstructed, whether the pressure switch and hydraulic alarm bell can operate normally. Improper closure may cause the pressure switch or hydraulic alarm bell to malfunction.
10、压力开关。有两组线：一组信号线，将压力开关动作信号传至火灾报警控制器，该信号可与保护区内一只感温火灾探测器的报警信号联动开启喷淋泵；一组控制线，连锁开启喷淋泵。
10. Pressure switch. There are two sets of lines: one set of signal lines, which transmits the pressure switch action signal to the fire alarm controller. This signal can be linked with the alarm signal of a temperature sensing fire detector in the protected area to activate the sprinkler pump; A set of control lines, interlocked to activate the spray pump.
11、水力警铃。其工作压力不应小于0.05MPa，距水力警铃3米处，声强不小于70dB,应设在有人值班的地点附近或公共通道的外墙上；与报警阀连接的管道，其管径应为20mm，总长不宜大于20m。
11. Hydraulic alarm bell. The working pressure should not be less than 0.05MPa, and the sound intensity should not be less than 70dB at a distance of 3 meters from the hydraulic alarm bell. It should be located near a manned location or on the outer wall of a public passage; The diameter of the pipeline connected to the alarm valve should be 20mm, and the total length should not exceed 20m.
12、报警管路控制阀，平时常开。
12. The alarm pipeline control valve is normally open.
13、自动滴水阀。其实就是低泄高封阀，平时处于开状态，可以把由于压力波动误进入系统侧的少量水排掉；发生火情，有大量有压水进入系统侧时关闭。
13. Automatic drip valve. In fact, it is a low leakage and high sealing valve, which is usually in an open state and can discharge a small amount of water that accidentally enters the system side due to pressure fluctuations; When a fire occurs and a large amount of pressurized water enters the system side, it will be shut off.
14、放水阀。用于灭火后排掉系统侧的余水。
14. Drain valve. Used to extinguish residual water on the system side after fire extinguishing.
15、信号阀。图中未标出，报警阀进口、出口各一个，能将阀门关闭的信号反馈至火灾报警控制器。如果不采用信号阀，要用锁具将阀门固定在常开位置。
15. Signal valve. Not indicated in the diagram, there is one inlet and one outlet for the alarm valve, which can feedback the signal of valve closure to the fire alarm controller. If a signal valve is not used, a lock should be used to fix the valve in the normally open position.
16、雨淋系统管道充满水的时间不应大于2分钟。报警阀组应安装在便于操作的明显位置，且不能安装于发生冰冻的场所。距室内地面高度宜为1.2m；两侧与墙的距离不应小于0.5m；正面与墙的距离不应小于1.2m；报警阀组凸出部位之间的距离不应小于0.5m。安装报警阀组的室内地面应有排水设施，排水能力应满足报警阀调试、验收和利用试水阀门泄空系统管道的要求。
16. The time for the rain shower system pipeline to be filled with water should not exceed 2 minutes. The alarm valve group should be installed in a prominent location that is easy to operate and should not be installed in places where freezing occurs. The height from the indoor floor should be 1.2m; the distance between the two sides and the wall should not be less than 0.5m; the distance between the front and the wall should not be less than 1.2m; the distance between the protruding parts of the alarm valve group should not be less than 0.5m. The indoor floor where the alarm valve group is installed should have drainage facilities, and the drainage capacity should meet the requirements of alarm valve commissioning, acceptance, and the use of water test valve venting system pipelines.
