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).
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.
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.
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.
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.
