    Unit III Question 1 1. What constitutes a suitable water supply in an automatic sprinkler system? Sprinkler system ( Fig.1) consists of a network of trunk 8 and 6 distribution pipelines, constantly filled with the liquid extinguishing agent with sprinklers 7, and is intended for local extinguishing and localization of the fire in the room. The system consists of a power supply, which is a tank 1 with water and the water intake system with a filter and pump 2. For trouble-free and reliable operation of the main supply backbone network 8 in the device, there are two automatic vodopitatelya 3 (air tank) and 4 (water tank). From the backbone for production facilities of the building dates back to a secondary highway 5 with rows of distribution pipes 6, equipped with sprinklers 7. In the main supply line installed warning turbine 9. Sprinklers installed in horizontal pipelines, located under the ceiling (defined by the project). The pipe system is filled with water under pressure and constantly ready to extinguish the fire (Hiram S.,1873). Fig.1. Sprinkler system Question 2 1. Discuss the types of valves you might find within a sprinkler system. Control devices (valves) sprinkler systems have two types: - Air-filled emergency valves; Dry "sprinkler valve is a pressure control valve and is used to control the flow of water in the dry sprinkler systems at the opening of one or more sprinklers. The valve also allows activating a fire alarm is triggered when the system. Dry sprinkler systems are used in unheated rooms, garages, windows, attics and other similar objects exposed to low temperature, where you can not use a water-filled pipe. The dry sprinkler system is filled with compressed air or nitrogen. At autopsy sprinklers exposed to heat from a fire occurs pressure drop in the pipeline, which leads to opening DPV-1 and the water supply valve in the flow conduit system. - Filled with water emergency valves (Dana, Gorham,1919). Question 3 1. Describe the four basic pipe materials used in sprinkler systems. The four basic pipe materials used in a sprinkler systems are ferrous metal, copper, galvanized steel and plastic. Ferrous metal piping is the most commonly used of the four piping systems but it's downfall is that it will eventually corrode and it's very heavy." Copper piping is highly resistant to corrosion, has low friction loss, is lighter in weight than steel pipe. The main drawback of plastic pipe is that it may not be installed in areas where the ambient temperature exceeds spec
