Description
The utility model relates to a kind of lengthening aerial fog nozzle, is a kind of device from two source atomizing of liquids and air, and the inner surface that is mainly used in pipe fitting cools off.
Disclose a kind of air-flow in " tool technique " 1996 the 30th volumes No.8 " the spraying cooling of cutting region " literary composition and amplified atomizer, mainly constituted by Conic nozzle, nozzle body, aqueduct and flow control valve.The face of cylinder part at Conic nozzle rear portion and nozzle body coaxial line are set in the end of nozzle body endoporus, and form evenly narrow annular between the nozzle body endoporus and let out the air port, the close annular of Conic nozzle taper seat is let out on the same circumference in air port and is evenly equipped with apopore, apopore communicates with its interior axial water hole, aqueduct is installed in the endoporus of nozzle body, one end links to each other with axial water hole in the shower nozzle, the other end communicates with water inlet on being arranged at nozzle body through flow control valve, offers the air inlet that communicates with its endoporus on the nozzle body.Enter pressure-air in the nozzle body and let out the air port through annular and go out, because the wall attachment effect air-flow is along conical surface high-speed motion.The negative pressure that produces around the high-speed motion air-flow is come the ambient air suction, produces the air-flow amplification, will be smashed by the current that apopore flows out simultaneously, and the air-flow of carrying water droplet secretly forms very uniform vaporific in the focusing of the end of Conic nozzle.When using this air-flow amplification atomizer that cutting tool is cooled off, because its directionality is good especially, cooling effect can concentrate near the point of a knife, has favorable cooling effect.But be subjected to its structural limitations, when being used for heat treated pipe fitting cooled off, because of stretching into pipe fitting inside its inner surface being carried out evenly cooling fast, and influence thermal treatment quality.
The purpose of this utility model provides a kind of lengthening aerial fog nozzle that can be directly injected to aerosol pipe fitting inside, in order to the thermal treatment zone of pipe fitting inner surface is carried out evenly and fast cooling, improves the thermal treatment quality of pipe fitting.
The purpose of this utility model realizes by following technical solution.
A kind of lengthening aerial fog nozzle, have Conic nozzle, nozzle body, aqueduct and flow control valve, the face of cylinder part at Conic nozzle rear portion and nozzle body coaxial line are set in the end of nozzle body endoporus, and form evenly narrow annular between the nozzle body endoporus and let out the air port, the close annular of Conic nozzle taper seat is let out and is evenly equipped with the apopore that communicates with axial water hole in it on the same circumference in air port.It also has plinth and lengthening airduct, offers endoporus, the air inlet that communicates with endoporus, water inlet on the plinth, and the lengthening airduct is connected and installed between nozzle body and the plinth.Aqueduct is installed on the axial location in the nozzle body that connects as one, lengthening airduct and the plinth, and an end links to each other with axial water hole in the shower nozzle, and the other end communicates with water inlet on being arranged at plinth through flow control valve.
The apopore that is distributed in same circumference on the Conic nozzle taper seat is 6～20.
The cone-apex angle α of the taper seat of Conic nozzle is-30 °～+ 30 °, and the taper seat of Conic nozzle is actually a back taper when cone-apex angle α is-30 °～0 °, and guiding aerosol jet is to diffusion all around, the inwall of directive pipe fitting.
It is 30 °～160 ° conical aerosol diffusion disc that the front end coaxial line of Conic nozzle is equipped with a cone-apex angle β, adopts the smooth surface transition between the taper seat of its taper seat and Conic nozzle.The cone-apex angle α that the aerosol diffusion disc generally is installed in the Conic nozzle taper seat is 0 °～+ 30 ° a situation, so that guide the aerosol jet to diffusion all around, the inwall of high fast direction pipe fitting.
The advantage that the utility model is compared with prior art had is: because the employing of lengthening airduct and plinth, make shower nozzle can extend into pipe fitting inside, the thermal treatment zone that aerosol is directly injected to the pipe fitting inner surface is carried out evenly and fast cooling, has improved the thermal treatment quality of pipe fitting.Be-30 °～0 ° back taper or when the aerosol diffusion disc is installed particularly when Conic nozzle adopts cone-apex angle, can guide the aerosol jet to around diffusion, the inwall of direct directive pipe fitting further improves cooling effect.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Accompanying drawing is the structure chart of the utility model lengthening aerial fog nozzle.
As shown in the figure, the utility model lengthening aerial fog nozzle mainly is made of diffusion disc 1, nozzle body 4, aqueduct 5, plinth 6, flow control valve 8, lengthening airduct 10 and Conic nozzle 13.The face of cylinder part at Conic nozzle 13 rear portions and nozzle body 4 coaxial lines are set in the end of nozzle body 4 endoporus, and form evenly narrow annular between nozzle body 4 endoporus and let out air port 12, cone-apex angle α=20 of the taper seat 2 of Conic nozzle 13 °, the close annular of this taper seat 2 are let out and are evenly equipped with 6 apopores 3 that communicate with axial water hole in it on the same circumference in air port 12.The air inlet 9 that offer endoporus on the plinth 6, communicates with endoporus, water inlet 7, lengthening airduct 10 is installed on by being threaded between nozzle body 4 and the plinth 6.Aqueduct 5 is installed on the axial location in nozzle body 4, lengthening airduct 10 and the plinth 6 that connects as one, axial water hole in one end and the shower nozzle 13 links to each other, the flow control valve 8 of the other end through being installed on the plinth 6 communicates with water inlet 7 on being arranged at plinth 6, and the flow control valve 8 in the present embodiment adopts needle-valves.The front end coaxial line of Conic nozzle 13 is equipped with the conical aerosol diffusion disc 1 of cone-apex angle β=150 °, adopts the smooth surface transition between the taper seat 2 of its taper seat and Conic nozzle 13.
During work, the current that imported by water inlet 7 are regulated flows after aqueduct 5 is flowed out by the hole for water spraying 3 of shower nozzle 13 by needle-valve 8.Pressure-air imports plinth 6 by air inlet 9, enters the annular gas tank 11 between shower nozzle 13 and the nozzle body 4 through lengthening airduct 10, nozzle body 4, lets out air port 12 ejections through annular again.At a high speed the air-flow of ejection will be smashed by the water that hole for water spraying flows out when the ambient air suction is come, and carry secretly along the taper seat 2 of shower nozzle 13 high-speed motion forward.When the water of high-speed motion, gas mixture run into aerosol diffusion disc 1, change the direction of motion, fly out, form plate-like and spray mist along the conical surface of diffusion disc 1.
