Rainshower valve is a control valve used in automatic sprinkler fire extinguishing systems, mainly for controlling water flow and alarm. It can quickly open in the event of a fire, allowing water to flow into the valve chamber and enter the water distribution network, thereby achieving rapid fire extinguishing. The rain shower valve can be opened by electric, hydraulic, pneumatic, and mechanical means, with multiple starting modes such as electric start, wet transmission, dry transmission, and emergency manual start.
The working principle of the rain shower valve is to achieve automatic water supply by controlling the fire water supply pipeline. When the fire alarm system detects a fire signal, the rain shower valve will automatically open, allowing water to flow into the sprinkler system in one direction and simultaneously issue an alarm signal. This type of valve is commonly used in open systems such as rain shower systems, water curtain systems, and water mist systems.
The structure of rain shower valves is diverse, commonly including diaphragm and piston types. The diaphragm type rain shower valve uses a diaphragm to divide the main valve into upper and lower chambers, and uses the difference in area between the upper and lower chambers to generate water pressure to achieve the sealing of the main valve. The piston type rain shower valve has high working pressure and stable and reliable performance, suitable for occasions that require anti misoperation and waterproof hammer impact.
The rain shower valve can respond in a timely manner when a fire occurs, control the flow of water, effectively extinguish the fire, and there is no water in the pipeline during normal times. Therefore, it is suitable for highly dangerous places where the fire spreads quickly and the closed nozzle cannot effectively cover the fire area after spraying water.
