<P>PROBLEM TO BE SOLVED: To provide a fluid jetting joint that responds to a request for simultaneously executing fire extinguishing work of mist water discharge and one point water discharge and reduces the possibility that the sensible temperature of a fire extinguishing worker becomes too high or the fire extinguishing worker suffers heat exhaustion during the fire extinguishing work. <P>SOLUTION: The fluid jetting joint includes: a cylindrical joint body; a plurality of nozzle-hole heads arranged in a circumferential direction of the joint body; and a jet adjustment mechanism provided at least at either one of a joint body circumferential part closer to the axial rear than the nozzle-hole heads and a joint body circumferential part on the inner side in the cylinder radial direction than the nozzle-hole heads. The plurality of nozzle-hole heads are respectively inclined and oriented at a predetermined inclination angle with respect to the axial direction and configured to spray fluid with a flow rate adjusted by the jet adjustment mechanism from the plurality of nozzle-hole heads to the oblique side with respect to the axial direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
