Abstract
The invention discloses an oil sprayer with an effective oil dripping prevention function. The oil sprayer comprises an oil sprayer body, a needle valve, a needle valve body, an anti-impact protective sleeve of the needle valve body, an abrasion-resistant plating layer of the needle valve, an abrasion-resistant hole ring of the needle valve, and a self-cleaning protecting layer of the needle valve, wherein the lower part of the oil sprayer body is respectively provided with the needle valve and the needle valve body, the exterior of the needle valve body is provided with the anti-impact protective sleeve of the needle valve body, the needle valve is plated with the abrasion-resistant plating layer of the needle valve, the abrasion-resistant hole ring of the needle valve is arranged in a needle valve hole of the needle valve, and the self-cleaning protecting layer of the needle valve is also arranged in the needle valve hole. By adopting the method, the oil sprayer has the advantages that the sealing performance of a sealing conical surface of the needle valve body is good, the oil dripping of the oil sprayer is avoided, the abrasion-resistant property for the abrasion between the needle valve and a guide surface of the needle valve hole is better, and the internal leakage of the oil sprayer is effectively avoided.
Description
Technical field
The present invention relates to oil sprayer field, particularly relate to a kind of oil sprayer effectively preventing oil dripping.
Background technique
By fuel-oil atmozation in diesel engine fuel injection system, and be distributed in the parts mixed with air in firing chamber.It is primarily of oil nozzle and oil injector body composition.Its mounting point on cylinder cap and angle depend on the design of firing chamber.The spray characteristics of oil sprayer comprises atomized particle size, mist of oil distribution, oily Shu Fangxiang, range and diffusion cone angle etc., these characteristics should meet the requirement of combustion system of diesel engine, to make mixed Daqu and to burn perfect, and obtain higher power and the thermal efficiency, oil sprayer is divided into open type and enclosed two kinds, and open fuel injector structure is simple, but atomization badness, seldom be used, close fuel injector is widely used on various diesel engine.
But, the oil sprayer of present use finds weeping when easily there is end of injection, when oil sprayer works, the sealing cone of needle-valve body can be subject to needle-valve brute force attack frequently, add high-pressure oil flow constantly to eject from this, the conical surface can engender indentation or spot, thus loss of seal, cause oil sprayer oil dripping.In addition, needle-valve and needle valve hole guide surface wear and tear, needle-valve is to-and-fro motion continually in needle valve hole, in addition the intrusion of bavin well cuts dirt, and needle valve hole guide surface can be made to wear and tear gradually, thus gap increases or occurs pulling indentation, cause leaking in oil sprayer increasing, pressure reduces, and fuel injection quantity reduces, injection time is delayed, causes diesel engine starting difficulty.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of oil sprayer effectively preventing oil dripping, the good airproof performance of the sealing cone of needle-valve body, can not cause oil sprayer oil dripping, the wear-resisting property that needle-valve and needle valve hole guide surface wear and tear is good, has effectively stopped to leak phenomenon in oil sprayer.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of oil sprayer effectively preventing oil dripping, comprise: oil injector body, needle-valve, needle-valve body, needle-valve body shock resistance protecting jacket, needle-valve is wear-resistant coating, needle valve hole is wear-resistant, and hole is enclosed and needle valve hole self-cleaning protective layer, the bottom of described oil injector body is respectively arranged with described needle-valve and described needle-valve body, described needle-valve body is outside equipped with described needle-valve body shock resistance protecting jacket, described needle-valve is coated with the wear-resistant coating of described needle-valve, the needle valve hole of described needle-valve is arranged described needle valve hole wear-resistant hole circle, described needle valve hole is also provided with described needle valve hole self-cleaning protective layer.
In a preferred embodiment of the present invention, described needle-valve body shock resistance protecting jacket is made up of the surfacing alloy material of impact-resistant and high-wear-resistant.
In a preferred embodiment of the present invention, described needle-valve is wear-resistant, and coating is high abrasion, friction-reducing composite function nano-coating.
In a preferred embodiment of the present invention, described needle valve hole self-cleaning protective layer is self-cleaning nano titanium dioxide film with hard surface.
The invention has the beneficial effects as follows: the good airproof performance of the sealing cone of needle-valve body of the present invention, can not cause oil sprayer oil dripping, the wear-resisting property that needle-valve and needle valve hole guide surface wear and tear is good, has effectively stopped to leak phenomenon in oil sprayer.
Embodiment
Be clearly and completely described to the technological scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A kind of oil sprayer effectively preventing oil dripping, comprise: oil injector body, needle-valve, needle-valve body, needle-valve body shock resistance protecting jacket, needle-valve is wear-resistant coating, needle valve hole is wear-resistant, and hole is enclosed and needle valve hole self-cleaning protective layer, the bottom of described oil injector body is respectively arranged with described needle-valve and described needle-valve body, described needle-valve body is outside equipped with described needle-valve body shock resistance protecting jacket, described needle-valve is coated with the wear-resistant coating of described needle-valve, the needle valve hole of described needle-valve is arranged described needle valve hole wear-resistant hole circle, described needle valve hole is also provided with described needle valve hole self-cleaning protective layer.
Preferably, described needle-valve body shock resistance protecting jacket is made up of the surfacing alloy material of impact-resistant and high-wear-resistant.
Preferably, described needle-valve is wear-resistant, and coating is high abrasion, friction-reducing composite function nano-coating.
Preferably, described needle valve hole self-cleaning protective layer is self-cleaning nano titanium dioxide film with hard surface.
The present invention effectively prevents the beneficial effect of the oil sprayer of oil dripping from being: the good airproof performance of the sealing cone of needle-valve body of the present invention, and can not cause oil sprayer oil dripping, the wear-resisting property that needle-valve and needle valve hole guide surface wear and tear is good, has effectively stopped to leak phenomenon in oil sprayer.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
