　　湿式报警阀上各个部件的主要功能

　　The main functions of each component on the wet alarm valve

　　湿式系统 wet pipe sprinkler system

　　Wet pipe springler system

　　准工作状态时配水管道内充满用于启动系统的有压水的闭式系统。

　　A closed system in which the water distribution pipeline is filled with pressurized water for starting the system when in a quasi working state.

　　①湿式报警阀体；主要功能：控制水流单向进入系统，火灾时开启报警通路，准工作状态：阀瓣上下腔水压平衡（上腔压力略大），阀瓣关闭

　　① Wet alarm valve body; Main function: Control the one-way flow of water into the system, open the alarm path in case of fire, quasi working state: Balance the water pressure between the upper and lower chambers of the valve disc (slightly higher pressure in the upper chamber), and close the valve disc

　　③过滤器；主要功能：拦截杂质，保护警铃、压力开关、节流板孔等堵塞；准工作状态：滤网清洁无堵塞

　　③ Filter; Main functions: intercept impurities, protect alarm bells, pressure switches, throttle plate holes, and other blockages; Quasi working state: The filter screen is clean and unobstructed

　　④延迟器；主要功能：缓冲压力波动，防止误报警【系统因漏水等各种原因导致微小漏水，引起系统侧压力略微降低，从而导致小量水进入报警控制管路，进入延迟器，避免直接进入压力开关，导致消防误启动】准工作状态：内部仅存少量水，节流板保持畅通

　　④ Delay generator; Main function: Buffer pressure fluctuations to prevent false alarms. The system may experience minor leaks due to various reasons such as water leakage, causing a slight decrease in pressure on the system side. This can lead to a small amount of water entering the alarm control pipeline and the delay device, avoiding direct entry into the pressure switch and causing false fire protection. Quasi working state: Only a small amount of water is left inside, and the throttle plate remains unobstructed

　　⑤压力开关；主要功能：将水压信号转为电信号，启动消防泵及报警系统；准工作状态：触点常开。

　　⑤ Pressure switch; Main function: Convert water pressure signals into electrical signals, activate fire pumps and alarm systems; Quasi working state: The contact is normally open.

　　⑥水力警铃；主要功能：通过水流冲击机械结构发出声响报警（≥70dB）【告诉周边人员水泵已启动】，准工作状态：无水流入，铃锤静止

　　⑥ Hydraulic alarm bell; Main function: Sound alarm (≥ 70dB) is generated by water flow impacting the mechanical structure [to inform surrounding personnel that the water pump has started], quasi working state: no water flows in, and the bell hammer is stationary

　　⑦节流板；主要功能：让存储在延迟器内的水慢慢流出【多次的系统波动可能导致延迟器内冲满水，节流板将延迟器的水排出】，准工作状态：无水，保持畅通

　　⑦ Throttling plate; Main function: Allow the water stored in the delay device to slowly flow out [Multiple system fluctuations may cause the delay device to be filled with water, and the throttle plate will discharge the water from the delay device], quasi working state: no water, keep unobstructed

　　⑧试验阀【泄水阀，实物在后面】；主要功能：检测整个阀组含水力警铃、压力开关、是否启泵等【打开试验阀，系统侧水流走，系统侧压力降低、阀瓣打开、大量水控制报警管路检从而检测延迟器、水力警铃、压力开关等相关部件】准工作状态：常闭

　　⑧ Test valve [drain valve, physical item at the back]; Main function: Detect the entire valve group including hydraulic alarm bell, pressure switch, whether to start the pump, etc. 【 Open the test valve, the water flows away from the system side, the system side pressure decreases, the valve disc opens, and a large amount of water controls the alarm pipeline to detect the delay device, hydraulic alarm bell, pressure switch and other related components 】 Quasi working state: normally closed

　　⑨报警试验阀【也叫警铃试验阀】，主要功能：利用供水侧的水进入报警控制管路，从而检测延迟器、水力警铃，从而检测其是否正常，准工作状态：常闭

　　⑨ Alarm test valve [also known as alarm bell test valve], main function: using water from the water supply side to enter the alarm control pipeline, thereby detecting the delay device and hydraulic alarm bell, and checking whether they are normal. Quasi working state: normally closed

　　⑩压力表；系统侧压力表监测管网系统侧水压；显示系统侧静压，供水侧压力表监测水源供水压力，显示供水侧稳定压力值

　　⑩ Pressure gauge; System side pressure gauge monitors the water pressure on the pipeline system side; Display the static pressure on the system side, monitor the water supply pressure on the supply side with a pressure gauge, and display the stable pressure value on the supply side

　　补偿器【单向、小孔】；主要功能：平衡阀瓣上下腔压力波动，防止误动作；准工作状态：平衡阀瓣上下腔压力波动，防止误动作

　　Compensator [unidirectional, small hole]; Main function: Balance the pressure fluctuations in the upper and lower chambers of the valve disc to prevent misoperation; Quasi working state: Balance the pressure fluctuations in the upper and lower chambers of the valve disc to prevent misoperation
