Working of the Sprinkler
A sprinkler looks like a simple light bulb hanging in the middle of the roof. It has a temperature sensitive glass bulb or a part of two metal alloys that are fusible together. Once the temperature of its vicinity rises from the preset values a pressurized tap is raised and releases the pressurized water from the tanks through the whole pipe system. Various kinds of water sprinkler are available these days depending on the type and requirement where these are installed. Some of the most common observed sprinklers are wet pipe sprinkler system, dry pipe sprinkler system, and deluge systems. In dry pipe systems, instead of water pressurized gasses are stored. Gasses are preliminary oxygen and nitrogen. This kind of fire system is installed in the locations where there is a chance of damage from water.
