Abstract
The utility model discloses a high-pressure fine water mist nozzle which comprises a nozzle body and a fine water mist jetting hole, wherein the fine water mist jetting hole is embedded in the front of the nozzle body; a rotational flow atomization tangential slot is arranged in the rear end of the nozzle body in an embedding way; and a direct-jetting throttler is embedded in the rear part of the rotational flow atomization tangential slot, and is provided with a direct-jetting throttling water inlet in an embedding way. Two spouts of high-pressure water generated from a water supply end enter an inner chamber of the nozzle along the direction tangential to the inner wall surface of the nozzle to form a rotational flow, are mixed with direct-jetting high-pressure water in the inner chamber of the nozzle to form strong turbulent motion, and finally are sprayed out from the fine water mist jetting hole at the front end of the nozzle. In the utility model, the direct-jetting energy and the rotation energy of the high-pressure water are utilized, the radial momentum of fine water mist is improved, and the atomization angle of the high-pressure fine water mist is enlarged, therefore, the coverage area of the water mist is enlarged, the protection radius of isolation between flame and air is enlarged, the extinguishment efficiency is improved, and the after-combustion of fire is effectively prevented.
Description
Technical field
The utility model relates to a kind of high-pressure fine water mist fire-extinguishing system, especially a kind of heavy pressure fine spray nozzle.
Background technology
High-pressure water mist fire-extinguishing is that water is added to certain pressure, be atomized into small water droplet, little water droplet surface area is increased, meet the rapid endothermic gasification of fiery adstante febre, produce cool off, suffocate, effect such as radiation-inhibiting heat, can put out the condition of a fire quickly, have pollution-freely, on-the-spot destroy little, good extinguishing effect, water consumption is little, electrical insulating property good, be applicable to and put out A, B, C three class fire, characteristics such as easy to use that it is wide to use the fire-fighting fire extinguishing scope.
The heavy pressure fine spray nozzle is one of critical component in the fine water mist fire-extinguishing system, and the atomizing type of nozzle, inner flow passage molded lines and structural parameters are key factors of the thin water smoke atomization quality of decision.Atomization that it is good and continuous firing performance are the assurances of fire-fighting efficiency.The atomizing angle of traditional direct atomizer is little, and the radius of protection of incuring loss through delay flame and air insulated is little, and fire-fighting efficiency is lower, and atomizing effect is undesirable, and range of application is less.
Summary of the invention
For solving the problems referred to above of prior art, the purpose of this utility model is to provide the heavy pressure fine spray that a kind of atomizing angle is big, radius of protection is big, fire-fighting efficiency is high nozzle.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of heavy pressure fine spray nozzle, comprise nozzle body and thin jet spray hole, described thin jet spray hole is embedded in the nozzle body front portion, the swirling flow atomizing tangential slot is installed by embedded mode in described nozzle body rear end, described swirling flow atomizing tangential slot rear portion embeds the direct projection flow controller, and described direct projection flow controller is installed direct projection throttling blasthole by embedded mode.
Compared with prior art, the beneficial effects of the utility model are:
1, because the utility model has adopted the direct projection energy and the rotating energy of water under high pressure; improve the radial momentum of thin water smoke and enlarged the atomizing angle of heavy pressure fine spray; make the coverage of thin water smoke increase, the radius of protection of flame and air insulated increases, and has improved fire-fighting efficiency.
2, because the utility model has improved the momentum that turns to of thin water smoke, make droplet can penetrate space, the scene of a fire, realize degree of depth fire extinguishing, stop the fire resume combustion effectively.
Description of drawings
The utility model has 3 accompanying drawings, wherein:
Fig. 1 is a heavy pressure fine spray nozzle 2 d plane picture.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 1.
Among the figure, 1, thin jet spray hole, 2, nozzle body, 3, the swirling flow atomizing tangential slot, 4, the direct projection flow controller, 5, direct projection throttling blasthole.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.As Figure 1-3, a kind of heavy pressure fine spray nozzle, comprise nozzle body 2 and thin jet spray hole 1, described thin jet spray hole 1 is embedded in nozzle body 2 front portions, swirling flow atomizing tangential slot 3 is installed by embedded mode in described nozzle body 2 rear ends, described swirling flow atomizing tangential slot 3 rear portions embed direct projection flow controller 4, and described direct projection flow controller 4 is installed direct projection throttling blasthole 5 by embedded mode.
Method of work of the present utility model may further comprise the steps:
Two strands of water under high pressures that produced by the end that supplies water enter from swirling flow atomizing tangential slot 3 respectively, and the direction tangent along the nozzle inner walls face enters nozzle chamber, form eddy flow; Two strands of water under high pressures behind the formation eddy flow mix with the direct projection stream high pressure water that enters nozzle chamber by direct projection throttling blasthole 5, form strong turbulent motion; Thin jet spray hole 1 from spray nozzle front end sprays at last.
