Product Introduction:

When a fire breaks out, the fire detector sends out a signal, and through the fire alarm (or fire control center), the solenoid valve on the diaphragm deluge valve can be automatically opened (the quick-open valve can also be opened manually), so that the water in the pressure chamber can be discharged quickly , After the pressure is released, the water acting on the lower part of the valve clack quickly pushes the valve clack up and enters the system pipeline to spray water to extinguish the fire. At the same time, the water flows to the reporting pipe network, causing the hydraulic alarm bell to sound an alarm, and the pressure switch to act to send a signal to the duty room or start the fire pump to supply water.
