Abstract
The utility model relates to a gas fire extinguishing nozzle. The inlet end of the utility model is a screw opening, and the utility model and a fire extinguishing pipe network are connected through the screw opening. The bottom end of the utility model has jet holes. The end surface of the bottom end can be hemispherical. The jet holes of the bottom end are distributed on the hemispherical surface. The end surface can be also cylindrical, the jet holes of the bottom end are distributed on the circumference and the bottom surface of the cylindrical surface. The nozzles can eject fire extinguishing gas to form in a hemispherical scattering shape and a V-shaped scattering shape. The utility model can be used for quickly and effectively extinguishing a fire disaster.
Description
The utility model relates to a kind of fire services appliance, particularly a kind of novel Gas nozzle of extinguisher.
Existing Gas nozzle of extinguisher, the fire-suppressant gas that sprays is the state of gas, liquid two-phase coexistent, and the liquid phase part in the fire-suppressant gas after the injection needs secondary volatilization, gasification, and it is little to spray effective area, expulsion pressure is big, and is all not ideal enough on fire-fighting efficiency and safe coefficient.
Purpose of design of the present utility model is the Gas nozzle of extinguisher that the fire extinguishing tube net arrangement of a kind of and efficient, the big flow of design, mesolow power matches.
The utility model is realized by following mode: described Gas nozzle of extinguisher is a concavity cylindrical shell, and the openend of cylindrical shell is a screw socket, links by screw socket and fire extinguishing pipe network.The bottom of cylindrical shell has some spray orifices, and the bottom of described cylindrical shell can be a hemispherical, also can be cylindrical.
Good effect of the present utility model is: described nozzle can be injected into fire-suppressant gas hemisphere dispersion shape and V-arrangement dispersion shape, fire-suppressant gas sprays to the combustible fire extinguishing equably, the flame that rises can be enclosed in below the design height again, to reach the control intensity of a fire, the purpose that stamps out a fire.
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is spherical nozzle cutaway view
Fig. 2 is spherical nozzle-end stereogram
Fig. 3 is cylindric nozzle cutaway view
Fig. 4 is cylindric nozzle-end stereogram
As shown in Figure 1 and Figure 2, the openend of spherical nozzle is a screw socket, and its bottom is a hemispherical, spray orifice be uniformly distributed in around the mouth of hemispherical limit and 45 ° of lines around, hemispherical bottom has the main jet hole, the duct of described spray orifice is all along radially hemispherical.The fire-suppressant gas of ejection becomes the hemisphere dispersion shape.
As shown in Figure 3, Figure 4, the openend of cylindric nozzle is a screw socket, and its bottom is cylindrical, and the side of column and bottom surface have some spray orifices, and the spray orifice duct of its bottom surface is vertical with the bottom surface, the spray orifice duct of its column side face and side angle at 45.The fire-suppressant gas forming V-shape dispersion shape that sprays.
