Detailed description of the invention
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Described in Fig. 1-Fig. 6, a kind of target formula impinging stream nozzle of atomization non-blind area, comprising:
One nozzle body, this nozzle body comprises that one is provided with the drive end bearing bracket 4 of front cavity 410, one is provided with the rear end cap 6 of rear chamber 610, current chamber in described front cavity 410 and rear chamber 610 are interconnected and form, and the volume of rear chamber 610 is greater than the volume of front cavity 410, the end of described front cavity 410 is provided with taper diffusion spout 11
One is positioned at the target plate 3 directly over taper diffusion spout 11, and described target plate 3 provides a barrier force, is tiny water droplet by the atomization of water current spurting out from taper diffusion spout 11.
The spout of this nozzle is taper diffusion spout, and water spray is in the time that nozzle outwards sprays, and its runner expands gradually, water flow velocity slows down, and dynamic pressure reduces static pressure and increases, last under higher hydrostatic pressure, there is violent shock in current and target plate, produces ultrasonic wave by atomization of water current.
Target plate 3 is fixedly connected with an adjusting part, and described adjusting part spreads the distance of spout 11 for adjusting target plate 3 and taper, and described adjusting part is installed on connecting rod 5 ends.
Adjusting part comprises an adjusting knob 2, and an adjusting nut 1, and described adjusting knob 2 is threaded with adjusting nut 1.
With reference to Fig. 7, wherein connecting rod 5 is circular arc, and connecting rod 5 cross sections adopt the aerofoil profile section of tip fine stern; This connecting rod 5 adopts 90 ° of radians, therefore radial water flowing pressure can be dispersed on connecting rod 5 uniformly, avoids occurring local shear, causes connecting rod cracking.
Also comprise a coupling assembling being rotatably connected with rear end cap 6, described coupling assembling comprises the large aperture male-pipe 910 arranging from top to bottom, hex nut 7 and small-bore male-pipe 810, described large aperture male-pipe 910, hex nut 7 and the 810 three in one moulding of small-bore male-pipe; Its large pore male-pipe, hex nut and small-bore male-pipe internal run-through, form outer current chamber.
Further, large aperture male-pipe 910 is fixed on the internal thread 10 of rear end cap 6 by 9 rotations of large aperture external screw thread, and outer current chamber is communicated with interior current chamber, forms sudden expansion booster cavity 12.Usually, the volume in outer current chamber is less than the volume in interior current chamber.
The small-caliber end of this coupling assembling is used for connecting feed pipe, and large aperture end is used for connecting rear end cap, and because heavy caliber is connected with rear end cap, its bore is greater than the bore of feed pipe, and therefore water flows to the structure that forms sudden enlargement, is called booster cavity.
With reference to Fig. 8 (a), Fig. 8 (b) and Fig. 8 (c), be the schematic diagram of striking face of the present invention.Current flow out from spout, and clash into target plate formation striking face, and described striking face is 0-120 ° and faces directly or the conical surface.
Operation principle of the present invention is:
The recirculated water that carrys out self-water-supplying standpipe enters nozzle, current at a high speed enter sudden expansion booster cavity 12, water flow velocity reduces, and dynamic pressure reduces, and static pressure increases, current are sprayed by taper diffusion spout 11 under high hydrostatic pressure subsequently, and bump with target plate 3, under huge pressure impact extruded, produce ultrasonic wave, be tiny water droplet by atomization of water current, last under the guide functions of target plate 3, with the atomizing angle ejection of 180 °.
During through connecting rod 5, because connecting rod section is the aerofoil profile section of tip fine stern, when therefore spray stream is crossed connecting rod 5, do the flow-disturbing without desorption through the spray stream of atomization ejection, avoid the barrier effect of connecting rod 5 to produce atomization blind area.
By rotation adjusting knob 2, can flexible modulation target plate 3 spread the distance between spout 11 with taper, thereby realize the controllability of atomizing effect.
More than show and described general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
