Water-sprinkler systems appeared during the end of XIX century. Favorable results of protection forced inventors to pay serious attention to this kind of firefighting. Before the revolution of liability insurance, companies recognized the impact of fire sprinkler hydraulic calculations in factories to reduce losses.
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.
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.
Fuse trip. The plug is held in position by a mechanism formed by two metal plates joined with a weld, with a melting point of carefully calibrated. In a blaze, the heat generated softens the solder, causing the water pressure acting on the cap and then disarm the system to skip the plug, allowing the escape of liquid. The water goes through the hole and strikes against a sheet, designed to distribute the jet way to rain (deflector). Each spray has its own fuse, so that only those sprinklers that are in zone of influence of trigger.
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.
Another way to activate a sprinkler is associated with flame detector which opens the closed spray, which in this case is a solenoid valve (solenoid valve) when a flame occurs in area protected by the sprinkler. The advantage of this system is that, once the blaze is out, the water outlet is cut and, if reignite, reopens. With the system of sensitive element, it would take someone off the water supply or water damage could exceed those caused by the inferno.
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.
