Nozzle for fighting fires in buildings |
摘要 |
A firefighting nozzle that will generate a spray of water in a 360 three-dimensional pattern, giving off a big sphere of fine droplets of water is disclosed herein. The nozzle has a hollow spherical portion rotatably mounted to the end of a rigid tube. Apertures are formed in such a pattern that an efficient mist production is achieved. Furthermore, some of the apertures are provided at such an angle that the water jets exiting these apertures exert a torque sufficient to rotate the nozzle with respect to the rigid tube to which it is mounted. The nozzle may be mounted to the end of a hand carried rigid tube or to the end of an articulated arm of a firefighting truck
