ZSFW temperature sensing deluge valve

材质：

球墨铸铁

< As a small-diameter deluge valve, the temperature-sensing deluge valve is mainly used for fire separation in door openings, windows and other areas. It can also be used for directional fire separation in equipment and areas.
This valve adopts a diaphragm structure. The diaphragm divides the valve into a working chamber and a control chamber. While the water flow acts on the working chamber, the pressure water entering the control chamber from the water diversion hole acts on the diaphragm (and is connected to the nozzle at the same time) , due to the difference in the water-receiving area of the upper and lower diaphragms, the sealing performance of the valve disc is guaranteed.
When a fire occurs, due to the heating action of the temperature-sensing nozzle, the control cavity releases pressure and opens the diaphragm, and the water flow flows to the open water curtain nozzle to prevent the spread of the fire.
