Specific embodiment
The technical solution of the utility model, the utility model are described in detail below in conjunction with attached drawing and specific embodiment
Illustrative examples and explanation be used to explain the utility model, but be not intended to limit the scope of the present invention.
Referring to fig. 2, the gas push type fighting nozzle of the utility model includes the spray bowl of broadening formation, is equipped in the bottom of spray bowl
Spray orifice portion 6 offers center of orifices 3 at the center in spray orifice portion 6, offers side spray hole 2 in the periphery of center of orifices 3, described
Side spray hole 2 is uniformly distributed on the same circumference along the periphery of center of orifices 3, sprays the bottom center setting center of orifices 3 of bowl
Purpose at least one side spray hole 2 is the quantity by increasing spray orifice, covers fire source to expand extinguishing chemical after spray orifice ejection
Range, improve fire-fighting efficiency.
In fire extinguishing, center of orifices 3 and side spray hole 2 simultaneously spray dry powder fire extinguishing agent, the pore size phase in side spray hole 2
It is 1:2~3.25 Deng the aperture ratio of, side spray hole 2 and center of orifices 3, the aperture value range in side spray hole 2 is 2~3mm, spray orifice
