What is the function of deluge valve?
A deluge fire protection system has unpressurized dry piping and open sprinkler heads. The system is directly connected to a water supply and when the system is activated, a deluge valve will release the water to all the open sprinkler heads. The valve is opened when activated by a heat or smoke detection system.
What is a pre action deluge system?
Deluge Systems are normally used in special hazard installations where water must be applied to an entire area for protection. Pre-action Systems are used to protect areas where water damage from damaged sprinklers or piping must be avoided.
How is a deluge sprinkler system activated?
How is a Deluge System activated? The sprinkler heads on a Deluge system are fused together and operate as one when activated. The valve is opened when activated by heat or smoke detection systems. Once activated, the water is released into the piping and out of the sprinkler heads.
What is water deluge system?
Water spray deluge systems are typically used in hazardous environments where fires may spread very quickly or where valuable equipment surrounding the fire needs to be cooled. These systems are designed for use in a variety of special hazard applications.
How many types of deluge valves are there?
Deluge valve is available with several trims including wet pilot, dry pilot, electric release, manual release, etc.
How many types of deluge systems are there?
There are three main types of water deluge systems, components of which are shown below. From left to right, they are: fine water spray systems, sprinkler systems, and water spray systems.
What is the difference between pre-action and deluge system?
The major difference between a deluge suppression system and a pre-action system is that pre-action systems are filled with compressed air. The sprinkler heads remain closed until needed, and a pre-action valve holds back the water. Unlike deluge systems, these systems only cover an area that detects heat or fire.
What is the benefit of pre-action system?
Advantages of using pre-action fire sprinkler systems include: The dual action required for water release – The pre-action valve must operate and sprinkler heads must fuse. This feature provides an added level of protection against inadvertent discharge.
What is the difference between deluge and sprinkler system?
The main difference between a deluge sprinkler system and any other sprinkler system is the sprinklers themselves. A deluge system, however, has open sprinkler heads at all times. The pipes, instead of being filled with water, or pressurized air, are full of air at the surrounding atmospheric pressure.
How do I choose a deluge valve size?
When choosing a deluge valve, check the specs to be sure the valve has a high Kv (flow coefficient) for high flow capacity, suitable for the size and application. In the event of a fire, multiple valves in the system need to be opened, which can decrease the pressure enough to interfere with proper valve performance.
What is deluge valve trim?
This type of trim is basic trim required to operate the deluge valve. A solenoid valve for electric remote actuation and pressure switch for sensing & annunciation are optional. b) Type SH2-TWD and SH2-TDD. This trim type is a combination of components of normal trim along with the drip and drain trim.
What is fm200 system?
FM-200™ is a colorless, compressed liquefied gas used to extinguish fires and is a popular replacement for Halon fire suppression systems. FM-200™ fire suppression systems are pressurized with nitrogen, waterless, and upon activation, FM-200™ discharges as a gas to suppress the fire.
When does the deluge valve system return to its set position?
When the fire gets extinguished then the deluge valve system returns to its set position. It uses water for extinguishing fire. Water are easier to store and transport when compared to other fire extinguishing chemicals. Also they are relatively cheaper.
Why are deluge valve systems used in fire protection?
In essence, due to their wide scale use in this area, the deluge valve systems can be referred to as being one of among the fire safety devices. They are an inherent part in the fire protection systems.
How does a water spray deluge system work?
Water spray deluge systems have been an effective defence against fire. Wormald’s advanced technology takes this simple idea to a new level. At the heart of our systems are specialised spray nozzles, positioned at the correct location, to quickly bring fire under control and stop it spreading.
