Abstract

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.

Abstract

A fire suppressant system having a pipe system, spray nozzles connected to the pipe system and a control system for selectively charging the pipe system with foam. The control system includes a pilot line for generating a signal based upon sensing an environmental parameter and a first control valve for activating the system based upon the signal. Preferably, the first control valve forms i) an interior cavity for mixing the compressed air and compressed air liquid, ii) an outlet in fluid communication with the interior; iii) a first inlet, oriented substantially perpendicular to a flow through the outlet, in fluid communication with the interior and the compressed air; and iv) a second inlet, oriented substantially perpendicular to the flow, in fluid communication with the interior and the compressed air liquid.
