The invention discloses a high-pressure fine water mist nozzle and a working method thereof. The nozzle comprises a nozzle body and a fine water mist jet hole, the fine water mist jet hole is embedded in the front part of the nozzle body, and the nozzle body The rear end is installed with a swirl atomization tangential groove by means of embedding, and the rear part of the swirl atomization tangential groove is embedded with a direct-injection restrictor, and the direct-injection restrictor is installed in a direct-injection throttling water hole by embedding. Two streams of high-pressure water generated by the water supply end enter the inner cavity of the nozzle along the tangential direction of the inner wall of the nozzle, forming a swirling flow, and mix with the straight jet flow of high-pressure water in the inner cavity of the nozzle to form a strong turbulent flow; The water mist jet hole sprays out. The invention adopts the direct energy and rotational energy of high-pressure water, improves the radial momentum of the fine water mist and expands the atomization angle of the high-pressure fine water mist, increases the coverage of the fine water mist, and protects the flame from the air. The radius increases, which improves the fire extinguishing efficiency and effectively prevents the fire from re-igniting.
Description
Technical field
The present invention relates to a kind of high-pressure fine water mist fire-extinguishing system, especially a kind of heavy pressure fine spray nozzle and method of work thereof.
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 object of the present invention is to provide a kind of atomizing angle is big, radius of protection is big, fire-fighting efficiency is high heavy pressure fine spray nozzle and method of work thereof.
For achieving the above object, technical scheme of the present invention 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.
A kind of method of work of heavy pressure fine spray nozzle may further comprise the steps:
Two strands of water under high pressures that produced by the end that supplies water enter from the swirling flow atomizing tangential slot 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, form strong turbulent motion; Thin jet spray hole from spray nozzle front end sprays at last.
Compared with prior art, the invention has the beneficial effects as follows:
1, because the present invention 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 present invention 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 present invention 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 present invention 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.
A kind of method of work of heavy pressure fine spray nozzle 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.
