Technical Field

The invention relates to a double-channel foam spray gun.

Background

The existing foam spray gun can only spray one fire extinguishing agent generally, but can not spray two fire extinguishing agents with different properties from the same gun. A dual fire extinguishing agent spraying gun, such as 201210344566.7 (a dual fire extinguishing agent spraying gun and a method thereof), which can spray two fire extinguishing agents with different properties, is currently available, wherein a mixed jet is formed by colliding a superfine dry powder fire extinguishing agent jet ejected from a central spraying passage with a cone-shaped water or foam fire extinguishing agent jet, but the mixing of the two fire extinguishing agents is not ideal, and the fire extinguishing effect is to be improved.

Disclosure of Invention

The invention aims to provide a double-channel foam injection gun, when two foam liquids are mixed and injected, the two foam liquids enter a mixing channel after being dispersed through a first water inlet channel and a second water inlet channel, and the dispersed foam liquids are contacted more fully and mixed more uniformly in the mixing channel, so that the mixing effect of the two foam liquids is improved, and the fire extinguishing advantage of mixing the two foam liquids is exerted.

The technical scheme includes that the double-channel foam spray gun comprises a first water inlet channel, a second water inlet channel, a disperser, a mixing channel, a mixer, a gun barrel and a nozzle, wherein the front ends of the first water inlet channel and the second water inlet channel of the double-channel foam spray gun are respectively connected with a first pipeline and a second pipeline, the rear ends of the first water inlet channel and the second water inlet channel are respectively connected with the mixing channel, the three channels are of Y-shaped structures, the dispersers are arranged in the first water inlet channel and the second water inlet channel, and the mixer is arranged in the mixing channel.

As a further improvement of the technical scheme, the Y-shaped structure is a reducing Y-shaped structure, and the sectional areas of the first water inlet channel and the second water inlet channel are the same and are larger than a half of the sectional area of the mixing channel.

As a further improvement of the technical scheme, the disperser of the two-channel foam spray gun is of a cross-blade structure.

As a further improvement of the above technical scheme, the mixer of the two-channel foam spray gun is of a crossed blade structure.

When two kinds of foam liquid are mixed and sprayed, the first pipeline and the second pipeline respectively convey one kind of foam liquid, the dispersers in the first water inlet channel and the second water inlet channel enable the two kinds of foam liquid to enter the mixing channel after being dispersed, the dispersed foam liquid is contacted more fully in the mixing channel, and meanwhile, the mixer in the mixing channel can enable the two kinds of foam liquid to be mixed in a crossed mode repeatedly, so that the two kinds of foam liquid are mixed more fully and uniformly, and the fire extinguishing efficiency is improved; an adjusting valve core is arranged between the gun barrel and the nozzle, and the foam can be adjusted to be direct current injection or atomization injection.

Based on the technical scheme, the two foam liquids respectively pass through the first water inlet channel and the second water inlet channel and are dispersed by the disperser, then enter the mixing channel and are repeatedly mixed by the mixer, and finally are sprayed by the nozzle, so that the two foam liquids are mixed more fully and uniformly, and the fire extinguishing efficiency is improved.
