How a deluge valve works?
Deluge valves are hydraulically operated differential type valves used to control water supply to a deluge system. Deluge systems use open sprinklers or nozzles. Trim sets are used to control the operation of the valve.

What is a quick response fire sprinkler?
A quick response fire sprinkler is a fire sprinkler designed to react immediately upon sensing a fire. Typically quick response fire sprinklers are heat activated, where heat from a fire melts a fusible link that allows the fire extinguishant (usually water in the case of fire sprinklers) to put out the fire quickly. Fire sprinkler systems are an important part of a building's total fire protection system, which should also include fire alarms, fire extinguishers and, where appropriate, specialized fire suppression systems.
Which is the ONLY type of fire sprinkler system that is installed so that all sprinklers are open and spray water when the system activates?
A "deluge" system floods the entire system when sensors detect smoke or heat, and the sprinkler heads do not have individual valves, as would be found in most systems.
What causes a fire sprinkler to activate?
Ordinary fire sprinklers activate (open) when they get hot enough. They may be equipped with a "frangible-bulb" glass vial, which holds the valve shut until the liquid expands beyond a calibrated volume and bursts the glass. They may have a "fusible link", made from various metals and calibrated to separate (melt) at a given temperature, releasing a spring-valve. Other specialized sprinkler systems cannot be activated until there is also a smoke or other fire detector trigger that allows pressurized water into the system. One other special type is called "deluge" and the sprinklers do not have valves at all. When the smoke or fire detector (or manual emergency trigger) goes off, the water will pour from every sprinkler head. Many TV shows and movies use fictional deluge systems for comedic effects when someone "pulls the fire alarm" and sets off the sprinklers, which would not normally occur in a properly designed system.
How do I turn on the sprinklers in my yard?
To turn on the sprinklers in your yard, locate the control panel or timer for your sprinkler system. Set the desired watering schedule and duration, then activate the system using the designated button or switch. Make sure the water supply to the sprinklers is turned on as well.
What should I do if there is not enough water pressure for my sprinklers to function properly?
If there is not enough water pressure for your sprinklers to work properly, you can try adjusting the water flow or checking for any clogs or leaks in the system. You may also need to consult a professional to assess and potentially upgrade your water supply system.
How can I manually turn on sprinklers?
To manually turn on sprinklers, locate the control panel or valve box for your sprinkler system. Turn the valve to the "on" position or adjust the settings on the control panel to activate the sprinklers. Make sure to follow any specific instructions provided by the manufacturer for your sprinkler system.
Why are the sprinklers not turning on?
The sprinklers may not be turning on due to a malfunction in the system, such as a broken valve or a power issue. It is important to check the system for any visible damage or electrical problems to determine the cause of the issue.
What does deluge mean in a fire sprinkler system?
A deluge fire sprinkler system, unlike most ordinary systems, mean that the sprinkler heads do not have individual heat-sensitive valves. The sprinkler heads in a deluge system have no valves of their own, meaning they are always open and water will be sprayed out of them when the supply valve is turned on. There are limited uses for deluge systems, such as in a tire storage warehouse where it is important to put out a fire quickly and the massive flow of water will not cause major damage.
How are sprinklers connected in a fire protection system?
Sprinklers in a fire protection system are connected to a network of pipes filled with water. When a fire is detected, the heat activates the sprinkler heads, releasing water to extinguish the flames.
What is preaction sprinkler system?
A sprinkler system employing automatic sprinklers that are attached to a piping system that contains air that might or might not be under pressure, with a supplemental detection system installed in the same areas as the sprinklers. Preaction systems are typically installed in areas where water damage due to accidental discharge of the sprinklers or breakage of the piping is a concern, or damage in the sprinklers and piping due to freezing. There are three types of preaction systems: non-interlock,single interlock, and double interlock. non interlock: water flow to sprinklers upon fused sprinkler or detection single interlock: water flow upon detection Double interlock: water flow only when detection and sprinklers detect fire
