How is the wet alarm valve composed?

Speaking of the wet alarm valve device, it is composed of a hydraulic alarm bell, a retarder and a pressure switch, a pressure gauge, a drain valve, a test valve, an alarm test pipeline, and the like. The wet alarm valve is only a one-way valve that allows water to flow into the wet system and drive the alarm of the matched components under the specified pressure flow; and the retarder is a device applied to the wet alarm valve to prevent leakage of the water supply pressure and leakage of the alarm valve. The false alarm occurred; the hydraulic alarm is an all-weather sound alarm facility driven by water. It has no sparks during operation and can be used in explosion-proof places. The hydraulic alarm bell is composed of an aluminum alloy body, an aluminum alloy impeller, an aluminum alloy bell shell, a copper alloy nozzle and a copper alloy bushing. No maintenance and long service life. The modern wet alarm valve device and pressure switch, water flow indicator, sprinkler, signal butterfly valve, end water test device, spray pump, etc. form a ZS series wet automatic sprinkler system, which is a widely used automatic sprinkler system.
