Description
Technical field
The invention belongs to fire-fighting equipment technical field, in particular to a kind of big angle of flare foam fire-fighting spray head.
Background technique
Foam nozzle breaks up foam mixing liquid when working, and the foam mixing liquid broken up is sprayed with uniform form of foam
Out；It is required that the structure of foam nozzle makes the foam sprayed be evenly distributed, and foam mixing liquid cannot be atomized.But existing skill
The angle of flare of foam nozzle is small under art, and atomization is serious, and foam mixing liquid is unevenly distributed when spraying, and intensive in centre, both sides are dilute
The effect of state of dredging cannot handle frostproof froth n and isolation oil sump high fire in time, influence fire extinguishing system.
Therefore, the prior art is defective, to be further improved and developed.
Summary of the invention
The purpose of the present invention is to provide a kind of big angle of flare foam fire-fighting spray head, which being capable of processing promptly and accurately
Frostproof froth n and isolation oil sump high fire, and angle of flare is big.
To reach above-mentioned technical purpose, the present invention is realised by adopting the following technical scheme.
A kind of big angle of flare foam fire-fighting spray head, which is characterized in that the nozzle body including tubular, the nozzle body
Outlet is provided with wedge-shaped nozzle, has been symmetrically arranged wedge on the interior upper side in the exit of the wedge shape nozzle and inner underside face
Shape baffle, the cross section of the wedge-shape diversion block are isosceles triangle, the center line of the wedge-shape diversion block and the wedge shape
The center line of nozzle is overlapped, and has been symmetrically arranged stabilier on the upper side of the outlet end of the wedge shape nozzle and downside.
The characteristics of the technical program and further improvement lies in that:
The leading flank of the wedge shape nozzle and trailing flank are respectively set to extend out arc-shaped.
The cross section of the stabilier is semicircle；Semicircular diameter be greater than wedge-shaped nozzle outlet width.
The cross section of the stabilier is that smaller part is round.
The apex angle of the isosceles triangle is acute angle, and two waist edges are set as extending out arc-shaped edges.
Big angle of flare fire extinguishing sprayer of the invention is squeezed into foam solution in sprayer body by pumping, and foam solution is in sprayer body
Upper, middle and lower-ranking is divided by wedge-shape diversion block, the diversion trench formed by wedge-shape diversion block and wedge-shaped nozzle is again by upper and lower two layers
Foam solution be divided into left and right two parts, it is uniform from the outlet of wedge-shaped nozzle so that foam solution be made to be evenly distributed in wedge-shaped nozzle
Spray, stabilier to from wedge-shaped nozzle outlet spray foam solution carry out current stabilization, and can further expansion angle of flare, from
And it can preferably put out a fire；The spray head can processing frostproof froth n promptly and accurately and isolation oil sump high fire, and angle of flare is big, expands
Scattered angle can achieve 180 degree；The fire extinguishing sprayer intensity of spray irrigation is big, broad covered area and uniformly, stable action is reliable, service free dimension
Shield expense.

Specific embodiment
It referring to Fig.1, is a kind of complete section structural schematic diagram of big angle of flare foam fire-fighting spray head of the invention；The fire extinguishing sprayer
Nozzle body 1 including tubular, the outlet of nozzle body 1 are provided with wedge-shaped nozzle 2, the interior upside in the exit of wedge-shaped nozzle 2
Wedge-shape diversion block 3 is symmetrically arranged on face and inner underside face, the cross section of wedge-shape diversion block 3 is isosceles triangle, wedge shape
The center line of baffle 3 is overlapped with the center line of wedge-shaped nozzle 2, as shown in Figure 3；The upper side of the outlet end of wedge-shaped nozzle 2 and
Stabilier 4 has been symmetrically arranged on downside.
Wherein, the leading flank of wedge-shaped nozzle 2 and trailing flank are respectively set to extend out arc-shaped, as shown in Figure 2.
Wherein, the cross section of stabilier 4 is semicircle, as shown in figure 4, the semicircular diameter of institute be greater than wedge-shaped nozzle out
The width of mouth, as shown in figure 5, keeping angle of flare bigger.
Wherein, the cross section of stabilier 4 is that smaller part is round, as shown in Figure 2.
Wherein, the apex angle of isosceles triangle is acute angle, and two waist edges are set as extending out arc-shaped edges, as shown in Figure 3.
Big angle of flare fire extinguishing sprayer of the invention is squeezed into foam solution in sprayer body by pumping, and foam solution is in sprayer body
Upper, middle and lower-ranking is divided by wedge-shape diversion block 3, the diversion trench formed by wedge-shape diversion block 3 and wedge-shaped nozzle 2 is again by upper and lower two
The foam solution of layer is divided into left and right two parts, to make foam solution be evenly distributed in wedge-shaped nozzle 2, from the outlet of wedge-shaped nozzle 2
It uniformly sprays, stabilier 4 carries out current stabilization to the foam solution sprayed from the outlet of wedge-shaped nozzle, and being capable of further expansion diffusion
Angle, so as to preferably put out a fire, can by as needed by stabilier 4 be shaped to it is required in the form of；The spray head energy
Enough processing frostproof froth ns and isolation oil sump high fire promptly and accurately, and angle of flare is big, and angle of flare can achieve 180 degree；This goes out
Fire-fighting head intensity of spray irrigation is big, broad covered area and uniformly, stable action is reliable, service free maintenance cost.
Although embodiment of the present invention is described in conjunction with attached drawing above, the invention is not limited to above-mentioned
Specific embodiments and applications field, above-mentioned specific embodiment is only schematical, directiveness, rather than is limited
Property.Those skilled in the art are under the enlightenment of specification, in the range for not departing from the claims in the present invention and being protected
In the case where, a variety of forms can also be made, these belong to the column of protection of the invention.
