EXPLOSION SUPPRESSANT DISPERSION NOZZLE

摘要

An explosion suppressant dispersion nozzle (10) for dispersing suppressant material from a pressurized suppressant storage vessel (12) to a protected zone or room is disclosed. The nozzle (10) includes a cylindrical body section (20) presenting an inlet end (26) for attachment to the storage vessel (12) and a discharge end (28), and a concavo-convex cap section (24) attached to the discharge end (28). The body section (20) includes a plurality of circumferentially spaced windows (32) each presenting generally rectangular openings for dispersing suppressant material laterally from the nozzle (10). The cap section (24) includes a central orifice (48) aligned with the longitudinal axis of the nozzle (10) for dispersing suppressant material axially from the nozzle (10) and a plurality of circumferentially spaced holes (50) spaced radially from the central orifice (48) for dispersing suppressant material radially from the nozzle (10). The windows (32), central orifice (48), and holes (50) are cooperatively positioned and sized for achieving a nearly hemispherical discharge pattern from the nozzle (10) with little loss of dispersion velocity.
