Document Type and Number:
WIPO Patent Application WO/2020/071329
Kind Code:
A1
Abstract:
In order to provide a spray head for a liquefied fire-extinguishing agent, the spray head having excellent vaporization characteristics and and excellent characteristics for scattering the liquefied fire-extinguishing agent, and being configured so that it is possible to increase the fire-extinguishing range that can be covered by a single spray head and also possible to raise the rate at which noise is reduced, this spray head 1 for a liquefied fire-extinguishing agent comprises a spray head body 2 to which there is connected piping for supplying a liquefied fire-extinguishing agent, an orifice plate 3 that is installed in the spray head body 2 and that has formed therein orifices 31 through which the liquid fire-extinguishing agent passes, a block-shaped porous member 4 installed in an outlet part of the orifices 31, and a baffle plate 5 installed so as to be in contact with an end surface of the porous member 4 that is on the side opposite from the outlet part of the orifices 31, the baffle plate 5 being configured so as to cover at least a projected area portion of a circumscribed circle 31c of the orifices 31 at the end surface of the porous member 4, and moreover being configured so that the liquefied fire-extinguishing agent is released through a gap 6 between the spray head body 2 and the baffle plate 5.
