川消湿式报警阀工作原理：在火警时，着火处喷淋头被火烤爆（一般场所用68度喷淋头），湿式报警阀上端由于泄水，压力变小，这时湿式报警阀下端供水侧压力超过上端系统侧压力，喷淋稳压泵工作，顶开湿式报警阀阀门，湿式报警阀下端的水流过报警阀到达喷淋管网。一部分水，流向延迟器，装满延迟器后，水继续流向水力警铃报警，同时压力开关报警，启动喷淋泵。

Working principle of Chuanxiao wet alarm valve: In case of a fire, the sprinkler head at the fire location is burnt out by the fire (usually using a 68 degree sprinkler head). The pressure at the upper end of the wet alarm valve decreases due to water leakage. At this time, the pressure on the water supply side at the lower end of the wet alarm valve exceeds the pressure on the upper system side. The spray stabilizing pump operates and opens the wet alarm valve. The water flow at the lower end of the wet alarm valve passes through the alarm valve and reaches the spray pipe network. A portion of the water flows to the delay device. After filling the delay device, the water continues to flow to the hydraulic alarm bell, and at the same time, the pressure switch alarms to start the spray pump.

阀瓣关闭不严故障现象：延迟器排水口持续漏水；严重时会发生断续报警；报警阀异常灵敏或灵敏度降低。

Fault phenomenon of valve disc not tightly closed: continuous water leakage at the drainage outlet of the delay device; Intermittent alarms may occur in severe cases; Abnormal sensitivity or reduced sensitivity of the alarm valve.

处理方法：将报警阀的阀盖打开，清楚座圈及阀瓣垫面上的沉积物；更换垫片。

Processing method: Open the valve cover of the alarm valve and clear the deposits on the seat ring and valve disc pad surface; Replace the gasket.

延迟器故障故障现象：在进行末端试水装置试验和警铃试验时报警阀不能在5-90s时间内发出报警信号；试验完毕后。延迟器排水时间超过5min。

Delayer malfunction phenomenon: During the end water testing device test and alarm bell test, the alarm valve cannot send an alarm signal within 5-90 seconds; After the experiment is completed. The drainage time of the delay device exceeds 5 minutes.

处理方法：检查延迟器进水口、出水口、排水口的位置和接口尺寸是否符合产品要求，排水口附件是否齐备，否则应重新装配；检查排水口是否堵塞；延迟器排水管上下应设控制阀。

Processing method: Check whether the positions and interface dimensions of the water inlet, outlet, and drainage outlet of the delay device meet the product requirements, and whether the drainage outlet accessories are complete. Otherwise, they should be reassembled; Check if the drainage outlet is blocked; Control valves should be installed above and below the drainage pipes of the delay device.

报警阀压力表读数异常故障现象：压力表值异常处理方法：选择合适的压力表，保证压力表示值在压力表的1/3-2/3的量程区间之内，并应定期校检压力表；稳压装置的运行压力应符合消防要求；稳压水源均应从报警阀水源管道上引入，使水源能通过报警阀。

Alarm valve pressure gauge reading abnormal fault phenomenon: Pressure gauge value abnormal handling method: Select a suitable pressure gauge, ensure that the pressure indication value is within the range of 1/3-2/3 of the pressure gauge, and regularly calibrate the pressure gauge; The operating pressure of the pressure stabilizing device should meet the fire protection requirements; Stable water sources should be introduced from the alarm valve water source pipeline to allow the water source to pass through the alarm valve.

主排水阀故障故障现象：主排水阀的故障主要是阀的渗漏或损坏。如排水管滴漏不止，排水阀锈蚀卡死，难以操作。处理方法：水中杂物较多时，在报警阀的水源入口应设过滤器；主排水阀宜采用阀座、阀杆及阀杆螺母为铜或不锈钢材质的阀门；常检查，定期操作试验。

Main drain valve malfunction phenomenon: The main drain valve malfunction is mainly due to valve leakage or damage. If the drainage pipe leaks continuously, the drainage valve rusts and gets stuck, making it difficult to operate. Treatment method: When there are many impurities in the water, a filter should be installed at the water source inlet of the alarm valve; The main drainage valve should be made of copper or stainless steel with the valve seat, valve stem, and valve stem nut; Regularly inspect and conduct regular operational tests.

压力开关故障故障现象：压力开关误报警或不报警。处理方法：检查压力开关的小动作压力是否符合要求；检查压力开关触点的接触电阻和绝缘电阻是否符合要求；检查电气线路和信号模块是否正常。

Pressure switch malfunction phenomenon: Pressure switch false alarm or no alarm. Processing method: Check whether the small action pressure of the pressure switch meets the requirements; Check whether the contact resistance and insulation resistance of the pressure switch contacts meet the requirements; Check whether the electrical circuit and signal module are normal.

报警阀信号槽故障故障现象：报警水流量减小，水力警铃响度不够，甚不响。处理方法：改善水源的设置，增设符合要求的水源过滤器。发现报警水流减小时应及时清理信号槽。

Fault phenomenon of alarm valve signal slot: The alarm water flow rate decreases, and the hydraulic alarm bell is not loud enough, or even does not sound. Treatment method: Improve the setting of water sources and add water source filters that meet the requirements. If the alarm water flow decreases, the signal slot should be cleaned in a timely manner.

水力警铃故障故障现象：水力警铃在报警阀动作后不报警；水力警铃在报警阀动作后断续报警或警铃响度不够。处理方法：当报警试验时，发现叶轮盒无水流出或水流甚少，一般是喷嘴堵塞，应检查过滤器的网孔尺寸；当报警试验时，叶轮盒排水正常，但无声响，应检查进水管与排水管是否反向（水力警铃如被拆装过，容易出现反向，应重新按要求组装）；检查铃锤是否脱落。

Fault phenomenon of hydraulic alarm bell: The hydraulic alarm bell does not alarm after the alarm valve acts; The hydraulic alarm bell intermittently sounds or the sound of the alarm bell is insufficient after the alarm valve is activated. Handling method: When an alarm test is conducted, it is found that there is no water flowing out of the impeller box or there is little water flow, usually due to nozzle blockage. The mesh size of the filter should be checked; When conducting an alarm test, the impeller box drains normally, but there is no sound. It is necessary to check whether the inlet and outlet pipes are reversed (if the hydraulic alarm bell has been disassembled, it is easy to reverse and should be reassembled as required); Check if the bell hammer has fallen off.
