Abstract
The utility model discloses a pipe fitting used for an automobile brake system, which is characterized by including a copper plating pipe substrate layer, a zinc plating layer and a chrome plating layer that are sequentially arranged from inside to outside; and a polyvinyl fluoride coating is arranged on the outer surface of the chrome plating layer. The copper plating pipe substrate layer is made of a cold-rolled carbonsteel belt plated with copper; the thickness of the copper plating pipe substrate layer ranges from 0.7 millimeters to 1.2 millimeters; and the thicknesses of the zinc plating layer, the chrome plating layer and the polyvinyl fluoride coating range from 8 micrometers to 25 micrometers, from 3 micrometers to 7 micrometers and from 8 micrometers to 25 micrometers respectively. The pipe fitting is strong in corrosion resistance, can resist for more than 3,000 hours verified by preliminary salt spray test experimentation, and has the characteristics of no harm to environment, long service life, good processing performance, excellent appearance mechanical properties and the like.
Description
Technical field
The utility model relates to the pipe fitting that a kind of automobile brake system uses.
Background technique
Be applied in a kind of pipe fitting in the automobile brake system in the existing technology, be made up of steel pipe substrate layer and spelter coating, this pipe fitting from inside to outside is steel pipe substrate layer and spelter coating successively.When above-mentioned pipe fitting uses in automobile brake system, because brake pipe belongs to automobile chassis spare, expose in air, when running into sleety weather, sleet adheres on the pipe fitting, and is very big to the corrosion of pipe fitting throughout the year.In addition,, also can certain corrosion be arranged to pipe fitting owing to be connected with fluid in the pipe fitting, if pipe fitting is corroded, in brake process, can be directly from the position generation explosion of corrosion, this is quite dangerous, very likely directly injures people's life and property safety.This shows that above-mentioned pipe fitting of the prior art awaits further to improve.
The model utility content
The task of the utility model is to solve the technological deficiency that aforementioned pipe fitting exists in the existing technology, provides a kind of automobile brake system to use pipe fitting.
Its technical solution is:
A kind of automobile brake system is used pipe fitting, and above-mentioned pipe fitting is followed successively by copper facing pipe substrate layer, zinc coating and chrome plating from inside to outside; Outer surface at chrome plating is provided with the polyvinylfluoride coating.
Above-mentioned copper facing pipe substrate layer adopts copper-plated cold-rolled carbon steel steel band to process.
The thickness of above-mentioned copper facing pipe substrate layer is 0.7～1.2 millimeter; The thickness of above-mentioned zinc coating, chrome plating and polyvinylfluoride coating is respectively 8～25 microns, 3～7 microns and 8～25 microns.
Above-mentioned chrome plating is a trivalent chromium coating.
The utility model corrosion resistance is strong, can reach more than 3000 hours through preliminary salt spray test checking, has environmental sound, long service life, good processability, characteristics such as appearance good mechanical performance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Figure is the structural principle schematic representation of a kind of mode of execution of the utility model, is its cross-sectional configuration.
Embodiment
In conjunction with accompanying drawing, a kind of automobile brake system is used pipe fitting, and above-mentioned pipe fitting is followed successively by copper facing pipe substrate layer 1, zinc coating 2 and chrome plating 3 from inside to outside; Outer surface at chrome plating is provided with polyvinylfluoride coating 4.
In the aforesaid way, chrome plating is preferably trivalent chromium coating.
In the aforesaid way, the thickness of copper facing pipe substrate layer is preferably 0.7～1.2 millimeter; The thickness of zinc coating, trivalent chromium coating and polyvinylfluoride coating is preferably 8～25 microns, 3～7 microns and 8～25 microns respectively.
In the aforesaid way, copper facing pipe substrate layer adopts copper-plated SPCC steel band system volume, promptly adopts copper-plated cold-rolled carbon steel steel band system volume; Be welded into tubing through soldering, this kind tubing corresponding tubing more of the prior art has good resistance to pressure; Corrosion resistance, mechanical property is outstanding.Zinc coating adopts continuous electric gold-plated coating process to obtain, and has good adhesive; When carrying out crooked experiment; Zinc coating difficult drop-off, and have higher corrosion resistance and salt-tolerant trait, and can better adhere on it for external layer polyvinylfluoride (PVF) coating and to lay the first stone.Trivalent chromium coating can not exert an influence to environment as passivating layer, meets the RoSH standard.External layer adopts PVF (Korea S is green) coating, has both improved salt-tolerant trait, makes the surface have excellent mechanical property again, reduced because of automobile in the process of running at high speed, the handstone that is flown up is beaten the probability of peeling off to pipe fitting, thereby has improved its life-span.
The utility model is mainly used in the automobile brake system, is its important part, and this system is used for the gait of march of Control of Automobile etc.The utility model is sent to wheel disc and wheel hub with the high pressure brake oil from braking overall pump.
The relevant technologies content of not addressing in the aforesaid way is taked or is used for reference prior art and can realize.
Need to prove that those skilled in the art can also make such or such easy variation pattern under the instruction of this specification, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should be within the protection domain of the utility model.
