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. |

1. A nozzle for atomizing and dispersing a discharge flow of suppressant from a fire suppression system into a fire zone, the nozzle comprising:
a bonnet having a concave surface extending radially outward and downward from an inlet port, the inlet port extends along an axis of symmetry of the bonnet and receives an outlet end of a fire suppression delivery pipe to mount the bonnet to the pipe; a deflector base co-axially aligned with and secured at a distance from the bonnet; a discharge port at an outer edge of the nozzle and defined by a gap between the bonnet and the deflector base; and a flow passageway extending between the inlet port and the discharge port; wherein the discharge port and flow passageway are configured to impart a streamwise vorticity to the suppressant flow discharged from between the bonnet and deflector base; wherein the flow passageway is formed between interleaved channels and lands in the deflector base and bonnet. |
