A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been exceeded. Fire sprinklers are extensively used worldwide, with over 40 million sprinkler heads fitted each year. In buildings protected by properly ...
Sprinkler heads operate individually. Note the red liquid in the glass bulb. A fire sprinkler system is an active fire protection method, consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system, to which fire sprinklers are connected. Although initially used only in factories and large ...
Sprinkler irrigation is the method of applying water in a controlled manner in way similar to rainfall. The water is distributed through a network that may consist of pumps, valves, pipes, and sprinklers. [ 1 ] Irrigation sprinklers can be used for residential, industrial, and agricultural usage. It is useful on uneven land where sufficient ...
The user (most likely a fire department) attaches a hose to the fire hydrant, then opens a valve on the hydrant to provide a powerful flow of water, on the order of 350 kilopascals (51 psi); this pressure varies according to region and depends on various factors (including the size and location of the attached water main).
This means that only the sprinkler heads at the fire location actuate – not all the sprinklers on a floor or in a building. However, certain systems, such as deluge systems [jargon], do spray water from all heads in the same zone upon actuation. Sprinkler systems help to reduce the growth of a fire, thereby increasing life safety and limiting ...
The Rain Bird horizontal action impact-drive sprinkler head was recognized as a historic landmark of agricultural engineering in 1990 by the American Society of Agricultural and Biological Engineers. [4] This invention led to sprinkler irrigation development that currently exceeds 50,000,000 acres (78,000 sq mi; 200,000 km 2) worldwide.
