Many types of sprinklers that can be classified according to its activation temperature, fast opening, orifice size of sprinkler discharge or flow rate, type of fuse element, jet application form, coverage area waterjet among many other factors involved in risk analysis and project design by the specialist (fire sprinkler hydraulic calculations).
Automatic sprinklers have an outlet for releasing water, a firing mechanism and a deflector to convert the output stream in a spray of water in area where there is fire. The trigger sprayer can be done by two mechanisms: a thermo-sensitive element or a flame detector. In this type of sprayer, the jet has a stopper that prevents the leakage of water and a stopper device releasing the trigger mechanism in this case is a device for releasing the plug.
There are other automatic, instead of the capsule are connected to a fire detector which sends an automatic valve that opens when the detector knows of a fire. When quenched, the switch closes the valve and, if applicable, would open again if the fire is revived. Systems differ from sprinklers sprayed water on the element that disperses the water these last is a mouthpiece designed to offer an angle of fog.
The spray outlet is somewhat less sharp slope of the teeth to its plane and a little more in diameter; glass valve polished, chamfered and sprinklers have higher gate outlet. For some time, some of the sprinklers manufacturers to reduce the cost structure used as a sealant rubber gasket. Thus it was not taken into account that over time the elastic properties of rubber deteriorates, and can result in loss of containment. But the worst thing that can happen to the adhesion of rubber sealing surfaces.
Thermo-sensitive bulb. The most common sprinkler glass bulb holds the cap in place and containing therein a liquid that does not fill the bulb, leaving a gap. When heat from a fire acts on bulb, the liquid boils and vapor pressure breaks the glass stopper and then releases the pressurized water contained pipe network, download and poured over the baffle forming a jet sprayed water mist.
The response time of these systems shall not exceed 300 seconds for low-temperature sprinklers (57 and 68 degrees C) and 600 seconds for the highest-temperature sprinklers. In 1806, an automatic fire extinguishing installation was patented by Englishman John Carey. He proposed to build in the protected area network of pipelines from the water head tank, and on the network to install sprinklers with small holes.
In protected space stretching combustible cord, which when blown open locks that hold the valve, the valve is released and the water flowed to a sprinkler. The device consisted of a cylindrical sealed tanks of about 95 tys.litrov system and 10-inch (250 mm) of the distribution of the aqueduct, covering all parts of the theater. Series of pipes of smaller diameter departed from the distribution pipes and were imbued with a number of half an inch (13 mm) holes through which poured water in case of fire. But the system was not automatic.
Another advantage of such a system is that the shot can be caused by smoke detection or detection of air ionization, since there are smoke detectors these extremes, while the temperature sensing function of temperature only. Its disadvantage is that, of course, is a more expensive installation.
