12 Bar Deluge Valve Diagram

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.

Technical Parameters

Diaphragm Deluge Valve

Diaphragm deluge valves are designed to control and regulate the flow of water in a deluge system, which uses open spray nozzles to provide complete coverage of a protected area in the event of a fire. The characteristic of the diaphragm deluge valves is that it can take into account both dry and wet sprinkler systems. The system uses a deluge valve to link with the alarm system. The nozzle is closed, and there is no water in the pipeline at ordinary times. Once the alarm is issued, it can be pre-filled with water, changing from a dry system to a wet system. This kind of system has high requirements, and the advantage is that there is no water in the pipeline at ordinary times, which can prevent misspraying or freezing and cracking, and is especially suitable for places where water is avoided.
