Abstract

The utility model belongs to the technical field of foam fire-fighting and discloses an axial foam fire-fighting injection device. The device comprises a water inlet joint, wherein an outlet of the water inlet joint is in threaded connection with a connecting cylinder; an outlet of the connecting cylinder is in threaded connection with a sprayer; multiple air suction holes are formed in the peripheral surface of the connecting cylinder; an axial nozzle groove is formed in the head of the sprayer. According to the device, the foam expansion rate can be timely and accurately treated, a flowing fire can be isolated, and the spread angle is large.

Description

A kind of axial foam fire-fighting injection apparatus
Technical field
The utility model belongs to foam fire extinguishing technique field, particularly a kind of axial foam fire-fighting injection apparatus.
Background technology
During foam nozzle work, foam mixing liquid is broken up, the foam mixing liquid of breaing up is sprayed with uniform form of foam; Require the structure of foam nozzle that the foam of ejection is evenly distributed, and foam mixing liquid can not be atomized.But under prior art, the angle of flare of foam nozzle is little, and atomization is serious, and the foam volume of ejection is little, can not process in time frostproof froth n multiple, can not completely cut off trickling fire, has influence on the effect of fire extinguishing system.
Therefore, there is defect in prior art, needs further improvement and development.
Utility model content
The purpose of this utility model is to propose a kind of axial foam fire-fighting injection apparatus, and the processing frostproof froth n multiple that this device can be promptly and accurately can completely cut off trickling fire, and angle of flare is large.
For realizing above-mentioned technical purpose, the utility model adopts following technical scheme to be reached.
A kind of axial foam fire-fighting injection apparatus, it is characterized in that, comprise water supply connector, the outlet of the described water supply connector connecting cylinder that has been threaded, the outlet of the described connecting cylinder shower nozzle that has been threaded, the periphery of described connecting cylinder is provided with a plurality of suction holes, and the head of described shower nozzle is provided with an axial spout groove.
The feature of the technical program and further improvement are:
The inlet segment of described water supply connector is straight tube shape, and water exit end is taper, and its outlet diameter is less than inlet diameter.
The inlet segment of described connecting cylinder is straight tube shape, and water exit end is taper, and its outlet diameter is less than inlet diameter.
Described a plurality of suction hole is evenly distributed on the periphery of the inlet segment of described connecting cylinder.
The external diameter of described water supply connector is less than the internal diameter of the inlet segment of described connecting cylinder, and the outlet diameter of described water supply connector is less than the outlet diameter of described connecting cylinder.
Described axial spout groove symmetry extends to the side of described shower nozzle.
Axial foam fire-fighting injection apparatus of the present utility model, sprays foam and water by pump by axial spout groove, by suction hole air amount, reach better foaming effect, thereby can better put out a fire; By changing the quantity of suction hole, processing frostproof froth n multiple that can be promptly and accurately, can completely cut off trickling fire, and axially spout groove symmetry extends to the side of described shower nozzle, has increased angle of flare, makes angle of flare can reach 180 degree; This injection apparatus stable action is reliable, service free maintenance cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of axial foam fire-fighting injection apparatus of the present utility model;
In figure: 1, water supply connector; 2, connecting cylinder; 3, suction hole; 4, shower nozzle; 5, axial spout groove.
The specific embodiment
With reference to Fig. 1, it is the structural representation of a kind of axial foam fire-fighting injection apparatus of the present utility model.This shower nozzle comprises water supply connector 1, the outlet of water supply connector 1 connecting cylinder 2 that has been threaded, and the periphery of connecting cylinder 2 is provided with a plurality of suction holes 3, the outlet of connecting cylinder 2 shower nozzle 4 that has been threaded, the head of shower nozzle 4 is provided with an axial spout groove 5.
The inlet segment of water supply connector 1 is straight tube shape, and water exit end is taper, and its outlet diameter is less than inlet diameter.The inlet segment of connecting cylinder 2 is straight tube shape, and water exit end is taper, and its outlet diameter is less than inlet diameter.
A plurality of suction holes 3 are evenly distributed on the outer peripheral face of the inlet segment of described connecting cylinder 2.
The external diameter of water supply connector 1 is less than the internal diameter of the inlet segment of described connecting cylinder 2, and the outlet diameter of water supply connector 1 is less than the outlet diameter of connecting cylinder 2.
Axial foam fire-fighting injection apparatus of the present utility model, by pump, foam and water, the outlet by water supply connector 1 sprays, and by suction hole air amount, reaches better foaming effect, by axial spout groove 5, foam and water are sprayed again, thereby can better put out a fire; By changing the quantity of suction hole 3, processing frostproof froth n multiple that can be promptly and accurately, can completely cut off trickling fire, and axially spout groove 5 symmetries extend to the side of shower nozzle, have increased angle of flare, make angle of flare can reach 180 degree; This injection apparatus stable action is reliable, service free maintenance cost.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, but the utility model is not limited to above-mentioned specific embodiments and applications field, above-mentioned specific embodiments is only schematic, guiding, rather than restrictive.Those of ordinary skill in the art, under the enlightenment of description, in the situation that do not depart from the scope that the utility model claim is protected, can also make a variety of forms, and these all belong to the row of the utility model protection.
