Atomizing nozzle for a fire suppression system

摘要

A nozzle for a fire suppression system has a bonnet and a deflector base. An inlet port extends through the bonnet along the axis of symmetry of the bonnet. The inlet port receives an outlet end of a fire suppression delivery pipe to mount the bonnet to the pipe. The bonnet has a frustoconical surface which extends radially outward and downward from the inlet port. The deflector base is secured to and co-axially aligned with the bonnet at a predetermined distance to create a flow passageway therebetween. The flow passageway imparts a down angle to a suppressant flow discharging from the nozzle to better disperse the suppressant within the fire zone. A discharge port at the circumferential edge of the bonnet and deflector base constricts the suppressant flow to atomize the droplets of liquid suppressant discharged into the fire zone.
