爆発抑制剤散布ノズル
Document Type and Number:
Japanese Patent JP4097701
Kind Code:
B2
Abstract:
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.
