Deluge Valve

Deluge system (automatic High Velocity Water Spray System) is a fixed fire protection system, which totally floods an area with pressurized water through a system of piping with open nozzles and sprinklers.

The system piping is empty until the controlling valve is activated by an electrical or other types of release systems. Deluge Valve has an inlet, outlet and priming chamber. Deluge Skid Type: With bypass, Without bypass, Pressure regulating type and Normal type.

The inlet and outlet are separated from the priming chamber by the valve chamber and diaphragm. In the” SET “position, pressure is applied to the priming chamber through a restricted prime line. The pressure is trapped in the priming chamber and holds the clapper on the seat due to the differential area. When the pressure is released from priming chamber faster than it is supplied through the restricted priming chamber line, the clapper moves and allow the inlet water supply to flow through the outlet into the system and associated alarm device.

In case of fire the Bulb sprinkler most burst at rated temperature due to heat which allow water in the detection pipe to drain out and in process allow the Deluge Valve to fully open.

As soon as the Deluge Valve opens the water most flow through the piping to flow water to all water spray nozzles mounted on the piping around the transformer. The water shall be sprayed in Hollow conical spray pattern to cover entire area of the transformer so that the fire on the transformer must cool due to emulsification as well as fire get extinguish to cutting off oxygen to coverage pattern of the nozzle.
