Abstract
The utility model relates to a water spraying nozzle for fire extinguishing, which is characterized in that the water spraying nozzle for fire extinguishing comprises an annular pipe which is provided with nozzles, an axial-flow blower is arranged behind the annular pipe, an applying valve is arranged in each of the nozzles, and pressure water is efficiently converted to high speed water and sprayed out. The utility model has the advantages of big fire suppression covering surface, high fire extinguishing efficiency, water saving, simple structure, etc. The utility model can be matched with a fire vehicle as well as carried by hands and is especially suitable for forest fire extinguishing.
Description
The utility model relates to a kind of extinguishing device, particularly a kind of mist fire-fighting shower nozzle.
Forest extinguishing device of the prior art mainly contains wind fire-extinguisher and waterpower spray, though the former can blow out a part of burned flame in use, also blows simultaneously and has fired part kindling material on the point of dying, and the efficient of going out is reduced.The waterpower spray is put out a fire by high-pressure injection water, and the area coverage of putting out the fire is little, and water consumption is big.
The area of putting out the fire that the purpose of this utility model is to provide a kind of and waterpower to go out the machine adapted is big, fire-fighting efficiency height, the mist fire-fighting shower nozzle of water-saving.
Above-mentioned purpose of the present utility model is to realize by such technical scheme, and promptly it is by nozzle, ring pipe, case, axial flow blower, security mesh panel, compositions such as support member.It is characterized in that nozzle is distributed on the ring pipe, constitute jet face forward, ring pipe is positioned at the front end of case, installation shaft flow fan on the support at its back side; One conical cavity is arranged between the ejiction opening of every nozzle and the inlet channel, a stopcock is arranged in this conical cavity, this stopcock is being axially arranged with helicla flute.
Said structure of the present utility model can further specify by accompanying drawing.
The utility model has following accompanying drawing:
Accompanying drawing 1 is the utility model cross-sectional view;
Accompanying drawing 2 is a left view of the present utility model;
Accompanying drawing 3 is the amplification cut-away view of the utility model nozzle.
Referring to accompanying drawing: the utility model is made up of nozzle ring 1, shape pipe 2, case 3, axial flow blower 4, security mesh panel 5, handle 6, support member 7 and stopcock 8.In the present embodiment, be evenly equipped with 28 nozzles on the ring pipe 2, in the nozzle stopcock be axially arranged with helicla flute, make its full cone chamber in after causing pressure flow to be obstructed and rotate, quickened the jet velocity of water and made it reach atomizing.
The utility model is owing to have said structure, its effect is very significant: i.e. the stopcock High Rotation Speed in the nozzle under the effect of hydraulic pressure, press water is become effectively or high speed water mist ejects, under the cooperation of axial flow blower, water smoke is delivered to flame range, cause flame range ambient air humidity to swash acute the rising, cause flame range to be lowered the temperature rapidly, suppress burning with this, the flame that suffocates reaches the purpose of rapid fire extinguishing. The utility model can make up with existing fire-fighting equipment easily, also can be used as portable use, further near flame range, improves fire-fighting efficiency. In addition, the special water-saving of the utility model, the granular size of its water smoke also can satisfy the optimum state of going out as required, and has compact conformation, reliability height, the advantage such as production technology is good.
