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).
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.
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.
Therefore, in case of fire, after the destruction of temperature sensor, the lid remains tightly spray glued to the hull and the water from the system is not received. Such cases were reported in the fire at many places in USA. After that, the producers was conducted large-scale action to recall and replace all sprinklers with rubber sealing rings. In some countries the use of sprinklers with a rubber seal is prohibited.
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.
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.
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.
