Hệ thống van chữa cháy kiểu deluge valve
2. Electrically (Fire Detectors)
3. Pheumatically (Glass Bulb Detectors)
4. Hydraulically (Glass Bulb Detectors)
– Each of these methodes (2 3 4) has a fire detection line that can activate the deluge valve
– Once the Detector operates the deluge valve will be activated, releasing (opening) the water supply to the system.
– Autommatic Fire Pumps can be activated by this proceedure and inturn extinguish/control the fire condition.
The Deluge system is designed to protect high hazard areas containing a severe fuel hazard with a high heat release rate by bringing a large number of open sprayers into action simultaneously in the event of a fire.
The most common approach of detecting a fire is the use of a sprinkler detection line permanently charged by air. In the event of a fire, the sprinkler detector heads directly affected by the fire will operate. The immediate drop in air pressure within the detector line releases the pressure against the Deluge valve diaphragm unit causing the Deluge Valve to open and discharge water through all the open water spray nozzles to rapidly control and extinguish the fire.
