发明名称 Inert gas suppression system nozzle
摘要 Nozzles (22) for reducing noise generated by the release of gas from a hazard suppression system (10) are provided. The nozzles (22) comprise a plurality of partitions (42, 44, 46, 48) that define a serpentine gas flow path through the nozzle. The flow path causes the gas to undergo a plurality of expansions and directional changes thereby reducing the velocity of the gas and dampening the generation of sound waves as the gas exits the nozzle (22) through the nozzle outlet (40).

主权项 1. A nozzle for introducing a gas into an area to be protected by an inert gas hazard-suppression system comprising: a nozzle housing having a gas inlet and a gas outlet; a nozzle stem having an axial bore formed therein; and at least a first innermost partition and a second outer partition located within said housing, said first partition defining an inner gas-receiving chamber into which said nozzle stem extends and into which a gas flowing through said gas inlet and said axial bore is received, said first and second partitions cooperating to define a first annular region therebetween, said first annular region being fluidly connected with said inner gas-receiving chamber by a first passage located at the distal end of said first partition opposite said gas inlet, said partitions being configured such that gas flowing from said chamber into said first annular region undergoes a 180° change in direction as it flows through said first passage resulting in the gas flowing in said first annular region in an opposite direction to the gas flowing in said inner gas-receiving chamber, said second partition partially defining a second annular region outboard of said second partition, said second annular region being fluidly connected with said first annular region by a second passage located opposite from said first passage, said second annular region being configured such that the gas flows in said second annular region toward said gas outlet in an opposite direction to the gas flowing in said first annular region, said nozzle stem comprising a fastening element operable to secure at least one of said partitions within said housing.
