摘要

PROBLEM TO BE SOLVED: To provide a fixed type powder fire extiguishant sprinkling nozzle for turning the fire extinguishant amount of the same sprinkling area to a small absolute minimum amount compared to the one of non-uniform sprinkling by enabling the uniform sprinkling. SOLUTION: This nozzle is provided with a cylindrical nozzle body 1 fixable to a ceiling or the like for which a bottom surface is opened, a jetting port 3 suspended at the center part of the nozzle body 1, a first deflector 4 in a vertical surface shape formed on the circumferential inner wall surface of the nozzle body 1 for scattering powder fire extinguishant horizontally radiated around from the jetting port 3 and a second deflector 5 in a conical surface shape whose conical vertex is present below the jetting port 3 for making the powder fire extinguishant which hits the first deflector 4 and scatters slide on the conical surface and fall down from the periphery.
