Deluge system pdf

A Deluge System is a fixed fire protection system in which the pipe system is empty until the deluge valve operates to distribute pressurized water from open nozzles or sprinklers. Deluge Systems A Deluge System is a sprinkler piping system employing open sprinklers or nozzles, connected to a water supply through a deluge valve which is closed when in set position. Deluge systems are more com- plex than wet pipe and dry systems because they contain more components and equipment.

The deluge valve is activated by operation of a fire detection system installed in the same area as the sprinklers (Figure 1). Various types of detection systems may be use including smoke, heat,. Deluge Foam Systems : In case of Fire, the Main Valve might be close (Management Decision wary about false operations).

A deluge system is one that does not use automatic sprinklers, but rather open sprinklers. Aspecial deluge valve holds back the water from the piping, and is ac-tivated by a separate fire detection system. When acti-vate the deluge valve admits water to the piping network, and water flows simultaneously from all of the open sprinklers. Inspection, Testing, and Maintenance Fire Sprinkler System NFPA 2 Chapter as amended by CCR, Title Page of 4. When the detection system is activated water discharges through all of the sprinkler heads in the system. The detection system is installed in the same area as the sprinklers.

Deluge Water Spray SysteAn automated water spray system where the water distribution piping is equipped with open spray nozzles for discharging over a protection area or equipment. The Inbal Automatic Water Control Valve used in this deluge system is a pressure operate sleeve actuate axial valve designed for use in fire protection systems. The Inbal Electrically Actuated Deluge Valve is used for automatic or manual operation.

Control Station, and Proprietary Protective and Central Station Signaling Systems. Deluge valve protects areas such as power transformer installation, storage tank, conveyor protection and other industrial application etc. With the addition of foaming agent deluge valve can be used to protect aircraft hanger and inflammable liquid fire.

Deluge Special Hazard was established to service the special hazard needs of the fire protection industry. The Deluge system incorporates an emergency valve, bypassing the fire detection system for manual operation. Designed for vertical or horizontal installation, a globe pattern, line pressure operated FDV-DHvalve features a direct elastomeric diaphragm seal. To order a Model E or Model F deluge or preaction system , first select the desired deluge valve and the appropriate deluge valve trim.

Next, choose a releasing trim and releasing device(s) depending on your application. For preaction systems, a riser check valve must also be ordere. Deluge Valve is known as a system control valve in a deluge system , used for fast application of water in a spray system. Also, a new deluge system (Figure 2), the blast initiated deluge system (BIDS), was developed that could discharge water at near 5fps. The heart of the BIDS consisted of a steel cone set inside a gal steel cylinder.

Gauges - Wet Pipe Systems 2-2. AFRL’s system offers the possibility of suppressing fires in facilities where ultra-fast burning materials are manufactured or handled. It is ideal for use during short production runs, temporary storage of hazardous materials, at remote locations where power is not available or when protection is required during a chemical or hazardous clean-up. This fire sprinkler system is cost efficient and low maintenance.

These types of fire sprinkler systems also need a smoke or heat detector like the pre-action system.
