Ductile Iron Flange End Diaphragm Deluge Valve
The valve body adopts professional fluid three-dimensional design, the diaphragm is made of high-quality double sandwich reinforced rubber material, the spring is made of stainless steel, and the valve body and valve cover are made of ductile iron. The solenoid valve installed on the outlet pipeline of the diaphragm chamber is normally closed, and the control chamber is connected to the water supply side through the control pipeline to maintain the water pressure in the diaphragm chamber and keep the valve in a closed state. When the fire alarm system detects the fire alarm signal, after being judged and confirmed by the control cabinet, it sends a start signal to the solenoid valve, the solenoid valve opens, the pressure of the diaphragm chamber drops, the deluge valve opens, and water is sprayed from the open nozzle to the entire protection area to perform the fire extinguishing function .
