Abstract
The utility model discloses a heat -resisting spray nozzle that resistance to wears, including nozzle body and nozzle hole, the nozzle hole includes post hole, first bell mouth and second toper hole, the aperture in post hole, first bell mouth and the second toper hole tapering of grow and first bell mouth gradually is greater than second toper hole, post hole, first bell mouth and the downthehole surface recombination of second toper have the diamond -like coating. The utility model discloses a spraying shower nozzle nozzle hole is divided into post hole, first bell mouth and second toper hole, and the hole surface coating one deck diamond -like film, improved the erosion resistant ability of shower nozzle by a wide margin.
Description
Technical field
The utility model belongs to jet atomization device field, relates to a kind of spray nozzle, is specifically related to a kind of spray nozzle simultaneously with excellent antiwear and heat resistance.
Background technology
Spray nozzle is the critical component in spraying, sand blasting unit, the working environment of spray nozzle is comparatively severe, during work, the spray slurry of HTHP can produce strong erosion effect to the working surface of nozzle, and therefore plain nozzle useful life longevity is poor, and replacement frequency is high.Particularly remarkable in this phenomenon special type spraying (as metal, ceramic spraying), for this reason, must redesign to strengthen its useful life longevity to spray nozzle, avoid frequent replacing.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of high temperature resistant, anticorrosive, is applicable to the extraordinary spraying nozzle of metal or ceramic spraying.
For this reason, the invention provides following technical scheme:
A kind of heat-resistant wearing and tearing spray nozzle, comprise nozzle body and nozzle bore, described nozzle bore comprises post holes, the first bellmouth and the second bellmouth, the aperture of described post holes, the first bellmouth and the second bellmouth becomes tapering that is large and the first bellmouth gradually and is greater than the second bellmouth, and described post holes, the first bellmouth and the second bellmouth inner surface are compounded with diamond-like coating.
Preferred as this programme, the tapering of described first bellmouth is 1.8-2.5, and the tapering of the second bellmouth is 1.2-1.5.
Preferred as this programme, the thickness of described post holes, the first bellmouth and the second bellmouth inner surface diamond-like coating is respectively 8-12 μm, 10-15 μm and 18-30 μm.
Preferred as this programme, described nozzle body material is silicon carbide ceramics.
Preferred as this programme, described diamond-like coating is hydrogenated diamond-like carbon film.
The beneficial effects of the utility model are: spraying nozzle nozzle bore of the present utility model comprises post holes, the first bellmouth and the second bellmouth, significantly reduce the erosion effect of spray paint to shower nozzle when ensureing spraying rate and pressure; The utility model is coated with one deck DLC film at post holes, the first bellmouth and the second bellmouth inner surface further, significantly improves the anti-erosion property of shower nozzle; The utility model optimizes the thickness of each several part coating further combined with each several part erosion mechanism, reduces product cost when guaranteeing service life.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is the utility model heat-resistant wearing and tearing spray nozzle structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Embodiment 1:
As shown in Figure 1, the heat-resistant wearing and tearing spray nozzle of the present embodiment, comprise nozzle body 1 and nozzle bore 2, described nozzle bore 2 comprises post holes 3, first bellmouth 4 and the second bellmouth 5, the aperture of described post holes 3, first bellmouth 4 and the second bellmouth 5 becomes large gradually and the tapering of the first bellmouth 4 is greater than the second bellmouth 5, and described post holes 3, first bellmouth 4 and the second bellmouth 5 inner surface are compounded with diamond-like coating.
In the present embodiment, the tapering of described first bellmouth 4 is 1.8-2.5, and the tapering of the second bellmouth 5 is 1.2-1.5.
In the present embodiment, the thickness of described post holes 3, first bellmouth 4 and the second bellmouth 5 inner surface diamond-like coating is respectively 8-12 μm, 10-15 μm and 18-30 μm.
In the present embodiment, described nozzle body 1 material is silicon carbide ceramics.
In the present embodiment, described diamond-like coating is hydrogenated diamond-like carbon film.
It should be noted that, the size of the present embodiment to nozzle body 1, post holes 3, first bellmouth 4 and the second bellmouth 5 does not specially require, but the aperture of post holes 3 is preferably 1-2mm, the first bellmouth 4 basal diameter is preferably 20-30mm, and the second bellmouth 5 diameter is preferably 35-45mm.
Spraying nozzle nozzle bore of the present utility model is divided into post holes, the first bellmouth and the second bellmouth, and bore area is coated with one deck DLC film, significantly improves the anti-erosion property of shower nozzle.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
