Abstract
The porous spraying plum-blossom ring flame nozzle of the pipe fitting of the utility model belongs to spray coating mechanical, it is to be made of column nozzle ontology, powder spray orifice and flame spray orifice, nozzle ontology is that cylindric, its center of circle is powder spray orifice, more than one flame spray orifice of arranging in ring week, and be divided into tilting section and parallel-segment from the inlet to the outlet by flame spray orifice, the aperture of parallel-segment is less than the aperture of tilting section, powder nozzle is divided into bigbore section and the small-bore accelerating sections of gathering materials from entrance to outlet.The porous spraying plum-blossom ring flame nozzle of the pipe fitting of the utility model, since nozzle flame spray orifice is axial axially parallel with nozzle flour opening, the combustion stream temperature and speed of powder feeding mouth front end are effectively reduced, thus the requirement that ensure that aluminium powder heating, accelerate.Experiments verify that the aluminium porous surface metal pipe coating voidage sprayed through the nozzle between 30% -35%, fully meets technique requirement.
Description
Technical field
The utility model belongs to spray coating mechanical more particularly to a kind of porous spraying plum-blossom ring flame nozzle of pipe fitting.
Background technique
Spray gun spray coating mechanical technical field be make spray treatment to equipment, part especially metal tube surface must can not
Few tool, and its important component part nozzle, then critical component whether being the function admirable of spray gun.Conventional metals powder
The quincunx nozzle of flame spraying gun, flame spray orifice are directed toward nozzle flour opening axial forward end region, this spray at a certain angle
The flame energy that hole is formed is high, speed is fast, and the metal powder for flying through combustion stream is effectively heated, accelerated, to obtain high-quality
Measure the metal coating of (coating porosity 5% is hereinafter, binding force is high)；This nozzle for spraying low-melting-point metal, (such as adopt by this technique
Aluminium powder) then powder scaling loss it is serious, the coating of requirement can not be formed.
Summary of the invention
The utility model provides a kind of porous spraying plum-blossom ring flame nozzle of pipe fitting for above-mentioned the deficiencies in the prior art.
The porous spraying plum-blossom ring flame nozzle of the pipe fitting of the utility model, is by column nozzle ontology, powder spray orifice and flame
Spray orifice is constituted, and nozzle ontology is that cylindric, its center of circle is powder spray orifice, more than one flame spray orifice of arranging in ring week, and by fire
Flame spray orifice is divided into tilting section and parallel-segment from the inlet to the outlet, the aperture of parallel-segment is less than the aperture of tilting section, powder nozzle from
Entrance to outlet is divided into bigbore section and the small-bore accelerating sections of gathering materials.
The aperture for being flame spray orifice as a further improvement of the utility model, is 0.3-1.0 millimeters.
It is as a further improvement of the utility model, a identical by the 4-12 that arranged in the heart, its ring week of powder spray orifice
Flame spray orifice.
The porous spraying plum-blossom ring flame nozzle of the pipe fitting of the utility model, since nozzle flame spray orifice is axial and nozzle flour opening
Axial parallel, the combustion stream temperature and speed of powder feeding mouth front end are effectively reduced, to ensure that aluminium powder heating, accelerate
It is required that.Experiments verify that the aluminium porous surface metal pipe coating voidage sprayed through the nozzle is between 30% -35%, it is completely full
Sufficient technique requirement.
Detailed description of the invention
Fig. 1 is the porous spraying plum-blossom ring flame nozzle schematic diagram of internal structure of pipe fitting of the utility model；
Fig. 2 is the porous spraying plum-blossom ring flame nozzle front end diagrammatic cross-section of pipe fitting of the utility model；
Fig. 3 is the rear end diagrammatic cross-section of the porous spraying plum-blossom ring flame nozzle of the pipe fitting of the utility model.
Specific embodiment
Spraying plum-blossom ring flame nozzle porous to the pipe fitting of the utility model with reference to the accompanying drawing, is described further:
As shown in Figure 1-3, the porous spraying plum-blossom ring flame nozzle of the pipe fitting of the utility model, is by column nozzle ontology 1, powder
Last spray orifice 2 and flame spray orifice 3 are constituted, and nozzle ontology 1 is that cylindric, its center of circle is that powder spray orifice 2, the arrangement of ring week are more than one
Flame spray orifice 3, and the aperture for being divided into tilting section 4 and parallel-segment 5, parallel-segment 5 from the inlet to the outlet by flame spray orifice 3 is less than inclination
The aperture of section 4, powder spray orifice 2 are divided into bigbore section 6 and the small-bore accelerating sections 7 of gathering materials from entrance to outlet；Flame spray orifice 3
Aperture be 0.3-1.0 millimeters；It is the heart with powder spray orifice 2,4-12 identical flame spray orifices 3 of having arranged in its ring week, flame spray
Hole is evenly distributed on the circumference near flour opening, axial, the flame spray orifice outlet diameter axially parallel with flour opening of flame spray orifice
It is adjustable, to adapt to the nozzle of different flour opening diameters.
