Abstract
The utility model relates to a fire-fighting device, which belongs to the atomizing nozzle technology field. The utility model is designed on the basis of an idea that an atomizing nozzle with simple structure, low gas consumption and outstanding atomization effect of the fire extinguishing agent is respected to obtain. The utility model comprises a connector with fluid inlet openings and a nozzle cover with fluid outlet openings, and the utility model is characterized in that at least one cylindrical groove symmetrically distributed around the longitudinal central axle and coaxial with each corresponding fluid outlet opening is arranged in the nozzle cover, a rotor which can freely rotate is arranged in the cylindrical groove, one end of the cylindrical groove is opened on the cavity between the connector and the nozzle cover, and the other end is connected with the fluid outlet openings. The utility model can eject water mist, thus being able to be used for extinguishing electrified fire below 1000V.
Description
Technical field
The utility model relates to a kind of fire plant, definite a kind of atomizer technical field that is used for extinguishing device of saying so.
Background technology
Existing water base fire extinguishing device, its subject matter are that the extinguishing chemical of nozzle ejection can not effectively atomize, and the water droplet that is dispersed into is thinless, irregular, and the diameter of water droplet can be as big as nearly millimeter; In addition, its water mark pollutes big, narrow application range, fire extinguishing weak effect.And the minimum water smoke droplet of average diameter stream not only is applicable to and the A that puts out a fire to save life and property, category-B fire also can be used for the charged fire of putting out a fire to save life and property.For this reason, people have carried out continuous effort in this respect, wish to improve and have nozzle now to the peptizaiton of extinguishing chemical and obtained some gratifying results, as the patent No. is 99258444.2 Chinese patent " fire-fighting with ultra-fine water liquid atomization device ", its atomizing duct is by a mix aperture, an air admission hole and an inlet opening are formed, and it is said that it can utilize the pressure of inert gas that efficient pulverizing of water liquid made mist, and the ejection superfine spray carry out high-effect fire-extinguishing.Though this patent makes encouraging progress, yet there is some deficiency, the one, the diameter of water droplets is still bigger; The 2nd, the structure of nozzle complexity is made processing and is difficult for; The 3rd, to spray air consumption simultaneously bigger because of gas-liquid.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure with regard to being at above-mentioned technical problem, is easy to process and the water spray extinguisher nozzle that can produce superfine water droplets that air consumption is little.
The purpose of this utility model is by adopting following technical scheme to be achieved:
This kind water spray extinguisher nozzle, it comprises that one has the joint of an inlet and the nozzle cover of the drag-out mouth that is threaded with it, it is characterized in that nozzle cap interior is provided with a minimum coaxial cylindrical groove of corresponding liquid outlet with each that is symmetrically distributed around vertical central axis, rotor free to rotate is installed in the cylindrical groove, the cavity of cylindrical groove one end opening between joint and nozzle cover, the other end is communicated with liquid outlet.
Have the Double-spiral guide groove on the cylinder of above-mentioned rotor;
One cylindrical cavity is arranged between above-mentioned joint and the nozzle cover.
Compared with prior art, advantage of the present utility model is: 1, the water smoke droplet average diameter of nozzle ejection is minimum, the following charged fire of 1000V of can putting out a fire to save life and property; 2, structure of nozzle is simple, makes handling ease; Compressed Gas is as driving gas during 3, because of fire extinguishing, and water sprays under the effect of Compressed Gas, so air consumption is little.
Description of drawings
The longitudinal sectional view of Fig. 1 water spray extinguisher nozzle;
The cutaway view that Fig. 2 water spray extinguisher nozzle cylindrical groove cooperates with rotor.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, the utility model is provided with joint 1, and an end of joint is provided with inlet 2, links to each other with foamite container by sebific duct etc.; The other end has a conical horn mouth, is threaded with nozzle cover 3.One cylindrical cavity 4 is arranged between joint and nozzle cover; Be provided with the coaxial cylindrical groove 6 of the corresponding liquid outlet with each that is symmetrically distributed around vertical central axis 5 in nozzle cover 3, the cylindrical groove upper end is communicated with lower ending opening and described cavity by an inverted cone channel with liquid outlet; The number of cylindrical groove and corresponding liquid outlet thereof can be decided as required, and as 3～6, in present embodiment, we have adopted 4; In each cylindrical groove, lay a rotor 7, certain space is arranged between rotor and the cylindrical groove, thereby rotor can rotate freely in cylindrical groove; Have Double-spiral guide groove 8 on the cylinder of rotor.After the device head of water spray extinguisher is opened, be stored in the interior extinguishing chemical of fire extinguisher cylindrical shell under the pressed gas effect, enter hydraulic spray nozzle by rubber tube, press water is crashed to pieces earlier with after the nozzle cover collision, divide four the road to flow into spiral-shaped guide groove in the rotor then, rotor is fast rotational under the pressure of water, thereby make water form rotary water current through four liquid outlet ejections on the nozzle cover, become the atomized water drip, water droplets runs into the vaporization rapidly of fire back, produces steam, absorb a large amount of heats in the water vapor process, scene of a fire environment temperature is on every side reduced rapidly, and simultaneously a large amount of steam are got rid of scene of a fire ambient air, play cooling and fire smothering effect.
