Product Description
Product Name: ZSFZ 150 Wet Alarm Valve China Guangbo Brand
1. The ZSFZ wet alarm valve is designed according to the requirements of GB5135.2-2003 "Automatic Sprinkler System Part 2: Wet Alarm Valves, Delays, and Hydraulic Alarm Bells", which only allows water to flow into the sprinkler system in one direction. It is a kind of one-way valve that drives the matching parts to alarm under the specified pressure and flow. The wet automatic sprinkler system composed of water flow indicator, pressure switch, sprinkler head, etc. is a very widely used fixed fire extinguishing system.
2. The pipe network of the system is filled with a certain pressure of clean water all year round, and it is in a working state for a long time. When a fire occurs somewhere in the protection area, the ambient temperature in the area rises. The organic matter in the heat sensitive element (glass ball) of the sprinkler The solution thermally expands and generates a great amount of internal pressure until the glass ball shell breaks, which opens the sprinkler head and sprays water, and automatically starts the entire system to emit an audible and visual alarm signal to achieve the purpose of fire alarm, fire control and fire suppression.
3. The wet alarm valve is a cover type alarm valve, which is mainly composed of a valve body, a seat ring and a valve flap. The entire valve body is divided into upper and lower chambers by the valve flap. The upper chamber (system side) communicates with the system pipe network. The lower chamber (water supply side) communicates with the water source, and a seat ring is provided in the valve body. On the seat ring, there are a plurality of grooved small holes leading to the inlet pipe of the retarder.
4. When the system is in the state of service, the small hole of the groove on the seat ring is covered and closed by the valve flap, and the alarm water channel leading to the hydraulic alarm is blocked; when the pressure difference between the upper and lower reaches a certain value, the valve flap opens ( When the differential pressure starts, the water flows from the water supply side to the system side, the alarm bell alarms, and the water spraying system sprays water; when the upper and lower pressures are frequently turned on, there is a small water supply valve on the valve flap, when the system side pipe network has a small leak Or when the pressure of the water source fluctuates, the water supply valve can be used to replenish the pipe network to balance the pressure of the upper and lower chambers and stabilize the valve flap, thereby avoiding false alarms.
