ABSTRACT:
Nozzle structure particularly adapted for use with pressurized fire suppressants is disclosed which includes an elongated, tubular, apertured body, and a visible, easily replaceable, fluid flow-directing slug disposed therein for controlling and directing lateral fluid flow from the nozzle. The slug is located in partial or complete blocking relationship to certain of the body sidewall apertures so as to define therewith outlet ports of desired effective dimensions and to control the spray patterns emanating therefrom. Use of a slug of different configuration serves to alter nozzle performance, discharge direction and discharge rate without need for any additional modifications of the nozzle. The annular end wall of the body allows the adjacent end face of the slug to be seen, such that appropriate coding can be applied to the slug end face for easy determination of the design discharge rate of the nozzle.
