Abstract
The utility model relates to a novel air valve, which comprises a valve rod and a valve plate, wherein the valve plate is arranged at the end part of one end of the valve rod, a conical working face is arranged on the valve plate, and a wear-resistant layer is arranged at the end part of the other end of the valve rod. According to the novel air valve provided by the utility model, a layer of wear-resistant and corrosion-resistant alloy is overlay-welded on the conical working face of the valve plate by adopting a special process, so that the air valve is not easy to wear in work; the air valve integrally adopts 21-4N, which has the performances of temperature resistance, high-temperature oxidation resistance, corrosion resistance and impact resistance, and the hardness of the rod end cannot be improved by adopting a tempering process; and in order to improve the wear resistance and impact resistance of the end surface of the valve rod, a martensite stainless steel sheet with appointed size is welded at the end part of the rod by adopting a special process, and the effects of high strength, high hardness, and excellent plasticity toughness and surface hardness are achieved after high-frequency tempering treatment, so that the service life of the air valve is prolonged.
Description
Technical field
The utility model relates to the engine part technical field, relates in particular to the engine valve actuating mechanism technical field.
Background technique
The most employing by camshaft drive valve actuating push rod of engine breathing door mechanism opens and closes the inlet and outlet valve through rocking arm.Up to the present, the shaft of valve actuating push rod all adopts single made, 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 receive 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, and technological requirement is high, and the performance performance index are held and are difficult for.The patent No. is that 2009202566776 novel valve provides a kind of valve for this reason; It is provided with a wearing layer at the valve block end; Can effectively improve shock-resistant, the wear-resisting property of valve block working surface, improve the working life of valve, but the existing valve valve rod the other end has no protective layer; Be damaged easily when receiving impact, friction, need further to improve.
The model utility content
The purpose of the utility model provides a kind of novel valve, makes the valve two ends all have good shock resistance, wear-resisting property, makes it have good working performance and long working life.
The technological scheme of the utility model employing is for this reason: the utility model comprises valve rod and valve block, and said valve block is arranged on the end of valve rod one end, and valve block is provided with the taper work face, and said valve rod the other end end is provided with wearing layer.
Said taper work face is provided with the alloy wear-resisting layer.
The utility model has the advantages that: the novel valve of the utility model on the taper work face of valve block, adopt the special process built-up welding one deck wear-resistant, corrosion resistant alloy makes valve in when work, and is not easy to wear; The whole 21-4N that adopts of valve, it has heatproof, resistance to high temperature oxidation; Corrosion-resistant and impact-resistant performance, this type steel cannot adopt quenching technical to improve rod end hardness, improve the wear-resisting and impact resistance of valve stem end face in order to satisfy; Adopt special process to weld the martensite type stainless steel sheets of a given size at boom end, have high tenacity, high hardness after handling through high frequency hardening; Good plasticity, toughness and surface hardness, thus can prolong the working life of improving valve.
Description of drawings
Fig. 1 is the structural representation of the utility model
1 is the alloy wear-resisting layer among the figure, the 2nd, and valve, 3 Martensitic Stain Less Steel sheets.
Embodiment
The utility model is provided with alloy wear-resisting layer 1 on the taper work face on the valve block of valve 2.Alloy wear-resisting layer 1 adopts anticorrosive, wear-resisting alloy welding powder, or stupalith, on valve 2, is provided with certain thickness Martensitic Stain Less Steel sheet 3, uses quenching technology to carry out enhancement process, reaches the purpose of prolongation in working life.
The Martensitic Stain Less Steel sheet 3 of the utility model can be 4Cr9Si2.
