Automatic sprinklers are a part fire extinguishing systems. Usually part of a fire protection system based on a water reservoir for the supply system and a network of pipes which are terminal elements. They usually are activated by detecting the effects of a fire since the temperature rise associated with fire, or smoke is generated by combustion (fire sprinkler hydraulic calculations).
In 1902 Frederick Grinnell patented the design Grinel alarm check valve. Water system Grinnell. A - short tube diameter of half an inch, screwed into a water pipe and closes flat bottom valve b; valve lever is held and backup c d. Backup d attached to the copper arc e apparatus with a weak solder which melts at a temperature of 73 degrees C.
But also widely funded manufacturers in devices sprinkler installations in factories. By the beginning of revolution, there were about 400 factories and plants are protected by fire-extinguishing installations. After the revolution of production has been established. The sprinklers were more or less accurate in terms of size of individual parts, the overall design and materials, reproduction sprinklers system.
Hence the name sprayed, which varies depending on the application that you want to give the system sprinkler. The most common use of these sprinkler-systems is the cooling of walls of a storage tank of flammable liquids because they are easier and less costly to maintain than a system of sprinklers, which moreover do not correspond to a pattern of dispersal water required by such facilities.
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.
These processes may take more or less depending on rate of release of surrounding heat to spray, the distance between the sprinkler and ceiling, the distance between the spray and the floor, the roof slope and other factors that have been extensively studied by the NFPA (National Fire Protection Association), UL (Underwriters Laboratories), FM (Factory Mutual), among other research and development in flame protection systems.
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.
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.
