Abstract
The utility model discloses a PVC. The PVC comprises a valve body (1), and a first protection layer (2) for preventing the valve body surface from being rusted and tarnished is arranged on the outer surface of the valve body (1). The PVC can prevent the valve body surface from being rusted and tarnished.
Description
Technical field
The utility model relates to the parts on a kind of automobile carburetor, specifically is a kind of PCV valve.
Background technique
The valve body of existing technology PCV valve is generally the irony part, and this valve body long term exposure is vulnerable to the infringement of air and other corrosive gass in air, makes surface oxidisation, the corrosion of valve body, even damages, thereby brings influence for the normal use of PCV valve.
The model utility content
The technical problem that the utility model will solve is, overcomes the defective of above existing technology, and a kind of PCV valve that can avoid valve body surface to get rusty, corrode is provided.
The technological scheme of the utility model is, a kind of PCV valve is provided, and comprises valve body, and the outer surface of said valve body is provided with one and is used to prevent that valve body surface from getting rusty, first protective layer of corrosion.
Described first protective layer is the color zinc layer of trivalent.
Also be provided with one on the internal surface of said valve body and be used to prevent that valve body surface from getting rusty, second protective layer of corrosion.
Described second protective layer is the color zinc layer of trivalent.
After adopting above structure, the utility model compared with prior art has the following advantages:
The outer surface of the utility model PCV valve is provided with one and is used to prevent that valve body surface from getting rusty, first protective layer of corrosion; Can avoid valve outer surface to receive the infringement of air and other corrosive gass through this first protective layer, thereby guarantee the normal use of PCV valve.
As improvement; Also be provided with one on the internal surface of said valve body and be used to prevent that valve body surface from getting rusty, second protective layer of corrosion; Can avoid valve interior surface to receive the infringement of air and other corrosive gass through this second protective layer, thereby guarantee the normal use of PCV valve.
Description of drawings
Accompanying drawing is the structural representation of the utility model PCV valve.
Shown in the figure 1, valve body, 2, first protective layer, 3, second protective layer.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Shown in accompanying drawing, a kind of PCV valve of the utility model comprises valve body 1, and wherein the PCV valve is an existing technology, shown in accompanying drawing, is not just detailing at this; The outer surface of said valve body 1 is provided with one and is used to prevent that valve body surface from getting rusty, first protective layer 2 of corrosion.
Described first protective layer 2 is the color zinc layer of trivalent, also just can adopt first protective layer 2 of other materials certainly, and these all belong in the protection domain of the utility model.
Also be provided with one on the internal surface of said valve body 1 and be used to prevent that valve body surface from getting rusty, second protective layer 3 of corrosion.
Described second protective layer 3 is the color zinc layer of trivalent, also just can adopt second protective layer 3 of other materials certainly, and these all belong in the protection domain of the utility model.
Below only be described, but can not be interpreted as it is restriction claim with regard to the most preferred embodiment of the utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of in the protection domain of the utility model independent claims, being done are all in the protection domain at the utility model.
