Abstract
The utility model relates to a novel valve which comprises a rod and a valve piece, wherein the valve piece is arranged at the end part of the rod, and is provided with a tapered working surface which is provided with a wear-resistant layer. The tapered working surface of the valve piece is fixed with a layer of wear-resistant and corrosion-resistant alloy by adopting a special technique, so that the valve is hard to wear when in work; by adopting 23-8N at the part of the valve piece, the novel valve has the performances of temperature resistance, high-temperature oxidation resistance, corrosion resistance and impact resistance; by adopting 4Cr10Si2Mo at the lower part of the rod, the novel valve has high strength, high hardness as well as good plasticity, toughness and surface hardness after heat treatment; and the performances of the two materials can adapt to the respective work environment, so that the service life of the valve can be prolonged.
Description
Technical field
The utility model relates to a kind of engine part, relates in particular to a kind of novel valve.
Background technique
The most valve actuating push rods that driven by camshaft that adopt of motivation inlet and exhaust valve mechanism open and close into by rocking arm, outlet valve.Up to the present, the shaft of valve actuating push rod all adopts single metal manufacturing, is by the steel manufacturing at first, and also useful in recent years aluminum alloy is made.The working surface of valve block is owing to be subjected to high frequent impact, and very easily wearing and tearing generally were to adopt heat treatment process to increase local hardness, to strengthen the wear and shock-resistant performance in the past.But because the performance limitations of material is difficult to the hardness of this working surface is handled and can be withstood shocks for a long time.When hardness was excessive, breaking appearred in embrittlement easily.Technological requirement height, performance performance index are held and are difficult for.
The model utility content
The utility model provides in order to overcome the above problems that a kind of intensity is big, wear-resisting, the novel valve of long service life.
The technical solution of the utility model is: comprise bar and valve block, described valve block is arranged on the end of bar, and valve block is provided with the taper work face, is provided with wearing layer on described taper work face.
The utility model has the advantages that: it is wear-resistant to adopt special process to fix one deck on the taper work face of valve block, and corrosion resistant alloy makes valve when work, and is not easy to wear; 23-8N is adopted at the valve block position, it has heatproof, resistance to high temperature oxidation, corrosion-resistant and impact-resistant performance, 4Cr10Si2Mo is adopted in the bottom of bar, it has high strength, and high hardness has good plasticity after the heat treatment, toughness and surface hardness, two kinds of materials performance separately can adapt to working environment separately respectively, thereby can prolong the working life of improving valve.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is bar among the figure, the 2nd, and valve block, the 3rd, wearing layer.
Embodiment
Novel valve comprises bar 1 and valve block 2, and described valve block 2 is arranged on the end of bar 1, and valve block 2 is provided with the taper work face, is provided with wearing layer 3 on described taper work face.
Claims (1)
1. novel valve comprises bar and valve block, it is characterized in that: described valve block is arranged on the end of bar, and valve block is provided with the taper work face, is provided with wearing layer on described taper work face.
