Operation of sprinkler spray nozzle
In case of fire, the thermosensitive liquid in the glass bulb will quickly expand, which will result in the blasting of glass bulb and discharging the seal assemblies, such as stopper and springs. The water flowing through sprinkler orifice will lash against the sprinkle-nozzle deflector, which will then form uniform sprinkling water flow to control or extinguish the fire.
