Sprinkler System Working Principle

The cap valve are held tightly against the orifice by a system of levers and links or other releasing devices pressing down on the cap and anchored firmly by struts on the sprinkler.

Sprinkler system working principle.

Principle of operation normally a wet pipe automatic fire sprinkler system is fully charged with water coming from a known reliable water supply. When the air is hot enough and reaches a sprinkler head it triggers a chain reaction. Each sprinkler is nothing but a faucet or tap as they call it in some countries a hole in the pipe through which water can escape into the building below. Sprinkler heads operate individually.

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 onto which fire sprinklers are connected. Principle of operation under normal conditions water discharged from an automatic sprinkler is restrained by a cap or valve. A sprinkler system is a network of pipes running through the ceiling of a building holding water under pressure. Fire sprinklers work because high heat triggers the sprinkler system.

When a blaze ignites the air directly above it heats rapidly. Not just any heat source will trigger a sprinkler system to activate. The installation is pressurised with the alarm valve secured in the open position.
