304 SS Net DN15 Fire Sprinkler Heads for Fire Fighting System , Fire Fighting Sprinkler
Fire Sprinkler Heads:
The reticular foam nozzle (PTW series) is the specialized unit to form and spray air foam, which is mainly used in low expansion extinguishing system. Foam proportionate system supply foam solution for these nozzles. When the foam solution was conveyed to nozzles by pipelines, the nozzle inhales air at the outlet to make foams and put out the fire.
Working Principle:
When pressurized foam solution flows through the cavity of the nozzle, its pressure will be reduced because of throttling. That will result in vacuum and inhale air. The foam solution then become foams after dispersed by nozzle.
Technical parameters:
