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).
A fire sprinkler is a device for extinguishing fires. Consists of an armature, with a pipe connected to a water pipe pressure. The pipe is closed with a cover subject by a glass capsule filled with a liquid whose boiling point is at a certain temperature (temperature trigger) which is subject against a disperser. When a fire occurs, the liquid boils and the steam breaks the capsule; the lid bounces, exits the water and crashes into the disperser sprinkling the burned area.
It consists of a thermo-sensitive element that is designed to destroy at predetermined temperatures, automatically causing the release of plug and the outlet of a water spray, which should extinguish the flame right in area where it has started. This device can be of two types: side of a disassembled sprayer without bulb or fuse Vista.
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.
Sprinkler is a component of fire-fighting system, irrigation head mounted in sprinkler installation (network of water pipes, which is always water or air under pressure). The spray outlet closed heat or thermo-sensitive bulb lock having a temperature of up to 343 degrees C. Upon reaching room temperature a certain value, locking the system soldered or bursts flask, and water begins to irrigate the protected zone. The disadvantage of such a system is relatively large inertia - head opened after about 2-3 minutes after the temperature rise.
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.
Fire-extinguishing system is maintained in working order. Sprinklers should be regularly inspected for mechanical damage, corrosion, coating damage, obstructions irrigation. Damaged sprinklers must be replaced. Even small leaks require immediate replacement of the sprinkler. To do this, have an arsenal of spare sprinklers and constantly replenish it. Sprinkler who have been exposed to heat of combustion products exceeds the value of maximum allowable operating temperature must be replaced.
First installation started in late XIX century, after the Englishman Stuart Harrison in 1864, has developed a sprinklers. Further development of sprinkler systems associated with the names of Americans Henry Parmelee and Frederick Grinnell. By 1882 in the United States for 200 enterprises was established about 200 thousand. Sprinkler-design Parmelee. During the same year in England the first such installation was witnessed.
