        湿式报警阀是自动喷水灭火系统的中枢神经，它的正常工作与否直接影响着整个系统的正常运行，因此对湿式报警阀的日常维护十分重要。

　　1、应半月检查一次警铃转动是否正常，检查时打开放水阀，闸阀报警阀瓣因水压差而自动打开，水流入延迟器经20-30秒后，警铃发出报警声响。如果警铃不发出响声，应检查整个警铃管道，排除其水垢、泥沙及污物，使水流畅通，蝶阀防止报警失灵。若警铃校验旋塞关闭后，警铃仍发声，则应检查校验旋塞是否关紧、在报警阀的环形水槽上是否积聚了障碍物、报警阀瓣下的橡胶是否老化或皱褶。对这些故障应及时排除。

 　　2、半年检查一次流动水压，检查时打开放水阀，警铃发出报警声响，此时，压力表所显示的压力值不应明显下降，如果下降较为显著，应检查闸阀是否堵塞或未开最大；如果压力表所显示的压力下降比较明显，且警铃不报警，截止阀应检查湿式报警止回阀的阀瓣启动是否正常。

 　　3、检查阀瓣上橡胶垫片的密封面，清除附着在橡胶密封垫上的污物和异物；如有磨损或损坏，应及时更换。

　　4、每年应检查一次密封件和阀座环形槽，清除污物或异物；如有破损，应以备件更换。

 　　5、根据消防用水的水质情况，止回阀定期打开过滤器上排污口，清理脏物。

 　　6、日常注意消防水池的水位及水压和相应阀门所处状态是否符合规范要求。

 　　7、误报警的处理： 　　发现误报警时，可检查整个管网是否漏水，球阀检查延迟器溢出孔是否堵塞或排水不畅。打开泄放试验阀可排空系统内积水或检验供水管网是否堵塞。 　　检查湿式报警阀阀瓣组件与阀座之间是否密封不严，使大量的水进入延迟器。 　　检查管网中的喷头是否因意外原因导致将释放机构启动。 　　查出误报警原因后，应及时处理，以确保系统任何时候都处于良好的备用状态。

        Wet alarm valve is automatic sprinkler system, central nervous system, it's normal or not directly affects the normal operation of the whole system, therefore, wet alarm valves routine maintenance is very important. 1, an alarm should be turned half check is normal, check to play an open valve, alarm valve flaps open automatically due toFILTER SERIES water pressure, water flows into the delay device by 20-30 seconds after the alarm sounds an alarm. If the alarm does not beep, the alarm should check the pipes, with their scale, sand and dirt to flow unimpeded, to prevent alarm failure. If the alarm check cocks closed, the alarm still sound, it should check whether the relevant check cocks tight, circular tank at the alarm valve is accumulated on the barrier, alarm valve flap or fold of rubber is aging. BALANCING VALVESThese faults should be immediately removed. 2, six months, a flow check water pressure, check valve when the play opened, the alarm sound alarm, time, pressure gauge shows the pressure values should not be decreased, if the drop is moreWATER POWER CONTROL VALVE significant, should check whether the plug or gate valve to open maximum; If the pressure gauge shows the decreasing, and the alarm does not alarm, check valve check valve alarm valve wet start is normal. 3, check valve valve sealing surface of the rubber gasket, rubber sealing pad attached to remove the dirt and foreign matter; if worn or damaged should be replaced. 4, should be checked once a year sealAPI CAST STEEL VALVES and valve seat ring groove, remove dirt or foreign bodies; if damaged, should spare parts replacement. 5, according to fire the water quality of water, regular filter on the discharge port to open, clean dirt. 6, daily attention to the fire pond water level and water pressure and the corresponding valve in which the state meets specifications. 7 False Alarm handling: Found that false alarm, it can check whether the pipe leakage, check the overflow hole is blocked delayed or poor drainage. Open the bleed valve to empty the system test or test waterFORGED STEEL VALVES supply network is blocked. Wet alarm check valve components and valve seat is Mifengbuyan between, so a lot of water into the delay device. Check whether the pipe network in the nozzle accidentally causes the release mechanism starts. Find out the reasons for false alarms, it should be promptly addressed to ensure the system at all times in good standby.
