Abstract
A novel air valve. The utility model relates to an engine part field especially relates to engine valve technical field. The technical scheme of the utility model is that: the valve plate comprises a rod and a valve plate at the end part of the rod, wherein a conical working surface is arranged on the valve plate, and a wear-resistant layer is arranged on the conical working surface of the valve plate. The novel valve adopts a special process to fix a layer of wear-resistant and corrosion-resistant alloy on the conical working surface of the valve block, so that the valve is not easy to wear during working; the valve plate part adopts 5Cr21Mn9Ni4N which has high temperature resistance, corrosion resistance and impact resistance, the lower part of the rod adopts 4Cr9Si2 which has high strength and high hardness, and the valve plate part has good plasticity, toughness and surface hardness after heat treatment, and the respective performances of the two materials can be respectively adapted to respective working environments, thereby prolonging the service life of the valve.
Description
Technical field:
The utility model relates to the engine part technical field, relates in particular to the engine valve technical field.
Background technique:
Engine breathing mechanism is most to adopt the valve actuating push rod that driven by camshaft to open and close the inlet and outlet valve by rocking arm.Be order up till now, 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-frequency percussion, 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, the hardness that is difficult to locate is handled and can be withstood shocks for a long time.When hardness was excessive, breaking appearred in embrittlement easily.Technological requirement height, performance index are held and are difficult for.
Summary of the invention
The purpose of this utility model provides a kind of novel valve, and it is by fixing one coating at working surface, and this coating has wear-resistant, impact-resistant performance, can prolong its working life.
The technical solution of the utility model is: comprise the valve block of bar and boom end, valve block is provided with the taper work face, is provided with wearing layer on the taper work face of valve block.
Described wearing layer is stupalith or alloy material.
Novel valve of the present utility model adopts special process to fix wear-resistant, the anti-rotten alloy of one deck on the taper work face of valve block, makes valve when work, and is not easy to wear; 5Cr21Mn9Ni4N is adopted at the valve block position, it has high temperature resistant, corrosion-resistant and impact-resistant performance, 4Cr9Si2 is adopted in the bottom of bar, it has high strength, high hardness, have good plasticity, toughness and surface hardness after the heat treatment, 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
Accompanying drawing is a structural representation of the present utility model
1 is wearing layer among the figure, the 2nd, and valve.
Embodiment
On the valve block of valve 1, be provided with the taper work face, on the taper work face of valve block, establish wearing layer 1.Wearing layer 1 adopts anticorrosive, wear-resisting alloy welding powder, or stupalith.
Claims (2)
1, a kind of novel valve comprises the valve block of bar and boom end, and valve block is provided with the taper work face, it is characterized in that, is provided with wearing layer on the taper work face of valve block.
2, novel valve according to claim 1 is characterized in that, described wearing layer is stupalith or alloy material.
