Description
Technical field
The utility model relates to one and is used in fire-fighting foams shower nozzle, particularly a kind of air foam shower nozzle that improves frothing percentage.
Background technology
The space existing in fire hazard, is all furnished with foam nozzle above it, and foam nozzle is connected with the conveyance conduit of supplying with mix-froth liquid.In the time of the lower space partial combustion in space, to conveyance conduit filling foam mixing liquid, mixed liquor produces foam by foam nozzle immediately, and foam coverage is on comburant surface, allows comburant and air partition, reaches the object of fire extinguishing.
The foam nozzle of existing use, between parts, fix, liquid outlet is one or several irregular hole (it is regular also having), when mixed liquor ejection, track is fixed, can only rely on the Surface absorption portion of air of liquid, foamed time foam volume short and that blend is limited, and such shower nozzle exists following shortcoming:
1, outlet fix, the track of outflow is fixed, the foam of formation is very inhomogeneous, like this form foam be attached to burning object surperficial time, in uneven thickness, easily fragmentation, again become mixed liquor and trickle on ground.
2, outlet is fixing, and the liquid of outflow forms a column, and its inside is not easy to enter air, form bubble few and little, coefficient of foaming is low, and the object that reach fire extinguishing needs the long period, greatly increased the use amount of foam solution, so that sometimes foam solution spray is over, fire does not still go out.
Summary of the invention
For addressing the above problem, effectively improve mixing efficiency and the combined amount of air foam, save energy, improve fire extinguishing effect, this reality is novel provides a kind of air foam shower nozzle, comprise sprinkler body, it is characterized in that: described sprinkler body is by water inlet, enter water axle, circular port frame, wind wheel, guard forms, described circular port frame, wind wheel is set in into the outer of water axle and places, described circular port frame is provided with uniform circular port, the described import that enters water axle is connected with water inlet, enter and in water axle, be provided with water outlet oral pore, the inside of described wind wheel is hollow structure, outside is provided with the through hole communicating with inside, described wind wheel hollow bulb with enter water axle water outlet oral pore and communicate, described guard is located at the outer of circular port frame and wind wheel and places.
The described water outlet oral pore that enters water axle is located at both sides in the axle corresponding with wind wheel Vacancy.
Described wind wheel is a kind of foliaceous wind wheel.
The through hole of described wind wheel is located in the blade side of wind wheel.
Through hole on described wind wheel blade is minimum is two.
The blade of described wind wheel is a kind of cylindric blade or multi-prism taper blade.
Adopt after said structure, water inlet connects foam mixing liquid pipe, foam solution is flowed out by the through hole of wind wheel through the delivery port that flows into water axle again, the air mixing foam generated entering with circular port frame after flowing out, after mixing, spray uniform air foam via guard again, because wind wheel is a kind of foliaceous wind wheel, its through hole is provided in a side of on blade, when outflow, rely on the pressure of water to promote blade rotary, mixed liquor flows out with 360 ° of rotations of blade, strengthen and air contact area like this, improve air foam formation efficiency and growing amount, the foam volume that the utility model produces is large and bubble is even, sprinkling region is even, easily reach fire extinguishing object.
The real new structure practicality of this use, has effectively improved the efficiency that air foam generates, and has improved product usability and validity.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is a side schematic diagram of the present utility model.
In figure, be denoted as:
1 sprinkler body, 10 inlet ports, 11 enter water axle, 12 circular port framves, 13 wind wheels, 14 guards, 111 apopores, circular port 121,
131 through holes.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the utility model title is described in further detail, but does not form any restriction of the present utility model.
As Fig. 1, shown in 2, a kind of air foam shower nozzle, comprise sprinkler body 1, it is characterized in that: described sprinkler body 1 is by water inlet 10, enter water axle 11, circular port frame 12, wind wheel 13, guard 14 forms, described circular port frame 12, wind wheel 13 is set in into the outer of water axle 11 and places, described circular port frame 12 is provided with uniform circular port 121, the described import that enters water axle 11 is connected with water inlet 10, enter and in water axle 11, be provided with water outlet oral pore 111, the inside of described wind wheel 13 is hollow structures, outside is provided with the through hole 131 communicating with inside, described wind wheel 13 hollow bulbs with enter water axle 11 water outlet oral pores 111 and communicate, described guard is located at circular port frame 12 and places with the outer of wind wheel 13, water inlet 10 connects foam mixing liquid pipe, foam solution is flowed through and is flowed out by the through hole 131 of wind wheel 13 into the delivery port 111 of water axle 11 again, the air mixing foam generated entering with the circular port 121 of circular port frame after flowing out, after mixing, spray uniform air foam via guard again.
As the further improvement of technology, the described water outlet oral pore 111 that enters water axle 11 is located at both sides in the axle corresponding with wind wheel 12 Vacancies, so that mixed liquor enters wind wheel, 12 inside are flowed out by through hole 131 again.
As the further improvement of technology, described wind wheel 13 is a kind of foliaceous wind wheels, and the through hole 131 of described wind wheel 13 is located in the blade side of wind wheel, so that mixed liquor produces air foam along with 360 ° of outflows of blade rotary mix with air.
In the time of real work, when mixed liquor flows out, the pressure of dependence water directly promotes wind wheel 13 and rotates, the i.e. blade rotary with through hole, mixed liquor is also to flow out with 360 ° of rotations of blade, has so greatly strengthened and air contact area, improves air foam formation efficiency and growing amount.
In practical operation is produced, the blade of wind wheel 13 can be designed to a kind of cylindric blade or multi-prism taper blade, is designed in the accompanying drawings multi-prism taper blade.
The foam volume that the utility model produces is large and bubble is even, sprays region even, due to the distinctive rotation mode of new type nozzle, make large quantity of air enter the inside of fluid column, coefficient of foaming increases, and reduces the use of foam solution, the foam bubble forming is also more even more greatly, easily reaches fire extinguishing object.
