Fire suppression nozzle

摘要

A fire extinguishing device for the uniform distribution of compressed air foam for fire suppression, connected to a piping network of a CAF system. Multiple nozzles of different types are connected to a single body, set at specific angles both horizontally and vertically. Each nozzle is selected to provide a set discharge spray angle and positioned in the body of the device to provide the proper distribution. The device body has a female thread at the inlet for connection to the CAF system in addition to female outlets at the discharge for connection of spray nozzles. The device may be used to create a 360° spray pattern or a 120° spray pattern depending on the application.

主权项

1. A fire suppression system for directing compressed air foam (CAF) comprising:
a storage of CAF concentrate, air and water; a mixing chamber connected to the storage for receiving and mixing the CAF concentrate, the air and the water to create the CAF; piping extending from the mixing chamber; and a nozzle assembly nozzle assembly for distributing the CAF including:
a) a manifold body defining:
i) a central inlet at a proximal end connected to the piping for receiving the CAF;ii) a plurality of outlets in fluid communication with the central inlet and equally spaced about a distal end; andiii) a central outlet axially aligned with the central inlet and centrally aligned within the distal end, wherein a bore size of the central inlet reduces towards the plurality of outlets and the central outlet with sweeping smooth surfaces to minimize and avoid destruction of a quality of the CAF;b) a plurality of open nozzles coupled to the plurality of outlets for directing CAF; andc) a spiral nozzle coupled to the central outlet for directing CAF.
