The duplex mixing syringe of low-voltage rotational-flow atomizing nozzle.
Background technology
Atomization technique is very wide in industrial circle application, and communications and transportation, agricultural production, gardens sprinkling irrigation etc. have atomization technique should
Example, but wherein most is all mesohigh atomization, (is less than for low pressure atomizing, especially ultralow pressure atomization
Research 0.1MPa) is very few.Common low pressure atomizing is most of by spring pressurization, can only allow the interrupted injection of liquid, and nothing
Method realizes continuous injection.In the case of after being applied to plurality of liquid mixing in mist state injection, spring loaded side is used
Formula is it is impossible to meet user to the demand continuously sprayed, it is therefore desirable to which the mutation by cross section of fluid channel product carrys out larger fluid pressure
So as to realize that liquid is atomized.But existing realize the means of atomization in ultralow pressure atomising art by changing cross section of fluid channel product
Effect it is unsatisfactory.

The passage that two independent in three-way pipe 2 is flowed into ultralow pressure vortex atomizing nozzle 1 and finally ejected with mist state.
Although being set forth in above to technical scheme, it should be noted that：
1. arcuate limb passage S22 quantity is not limited to the specific quantity in above-mentioned embodiment, but can root
According to needing to select appropriate quantity, it is therefore preferable to 3 to 7 arcuate limb passage S22.
2. the quantity of the external thread part of spiral speedup part 12 is not limited to the specific quantity in above-mentioned embodiment, but
Appropriate quantity can be selected as needed, it is therefore preferable to 2 to 6 external thread parts.
3. following beneficial effect is also had according to the ultralow pressure vortex atomizing nozzle of the present invention.
The invention provides a kind of new ultralow pressure vortex atomizing nozzle 1, it can be advantageously applied to liquid initial
Situation of the pressure less than 0.1Mpa simultaneously has good atomizing effect.The present invention is added by the pressure chamber S1 in atomizer 1
Add spiral speedup part 12, improve the flow velocity of runner S liquid, meanwhile, increase laminar flow road S2 and axle center chamber S3 to increase liquid pressure
Power, spray chamber S4 Fluid pressure has been initial pressure decades of times, can be adapted to increase by spray chamber S4 diameter, reduction makes
The risk blocked during, and there is good atomizing effect, while reduce difficulty of processing.
The ultralow pressure vortex atomizing nozzle 1 of the present invention is former by the superposition being atomized using centrifugal spraying and axial center type simultaneously
Reason, flow formed eddy flow in eddy flow accelerated passage S11, S12 using liquid and accelerate, liquid is accelerated to flow into laminar flow road
S2, liquid is further speeded up by laminar flow road S2 arcuate limb passage S22, finally in nozzle shape into venturi water
Film, moisture film tear to form drop in atmosphere, and drop presentation is vaporific, and regular point that cone is initially formed from spray orifice portion S5
Cloth, suitable for the ultra low pressure scope less than 0.1MPa, there is good atomizing effect, and assemble simple.
The duplex blender of the present invention is due to using spiral speedup part 12 to cause mixed liquor in eddy flow accelerated passage afterwards
The distance flowed through in S11, S12 is longer, adds incorporation time and distance of the mixed liquor in this section, allows two kinds of decoctions to have foot
The enough time and space is sufficiently mixed.Because eddy flow accelerated passage S11, S12 increase the flow velocity and pressure of liquid, while nozzle
1 spray chamber S4 diameter is smaller, sprays that the diameter of the drop of appearance is smaller, and atomizing effect becomes apparent from, decoction coating
Thickness is thinner.Such effect is easy to user more preferably to control the thickness of coating, saves more mixed liquors.
Protection scope of the present invention is not limited to above-mentioned embodiment, as long as but meeting the claim of the present invention
The combination of technical characteristic is just fallen under the scope of the present invention.
