Abstract
A valve. The utility model relates to an engine part technical field especially relates to engine valve technical field. The utility model provides an above-mentioned technical problem's technical scheme as follows: the valve plate comprises a rod and a valve plate at the end part of the rod, and is formed by fixedly connecting the rod and the valve plate with a short rod, and a step circle is arranged at the connecting part. The utility model discloses a bimetal valve block position adopts 5Cr21Mn9Ni4N, and it has high temperature resistant, corrosion-resistant and shock-resistant performance, and 4Cr9Si2 is adopted to the lower part of pole, and it has high strength, high hardness, has good plasticity, toughness and surface hardness after the thermal treatment, and two kinds of respective performances of material can adapt to respective operational environment respectively to can prolong the life who improves 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, and for various reasons, valve actuating push rod body and other related components normal and motor is inconsistent with material.As everyone knows, metal heated is dilatable, and different materials has different expansion coefficient.In addition, that valve block needs is corrosion-resistant, the performance of high temperature and impact, and the lower end of bar needs high strength, high hardness and wear-resisting performance, with being difficult to embody different performances in a kind of material.Therefore, the valve weak point of making by identical material in working life.
Summary of the invention:
The utility model provides a kind of bimetal valve of the long service life of being made by two kinds of unlike materials at above problem.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: comprise the valve block of bar and boom end, it is by bar and is with the valve block of quarter butt to be formed by fixedly connecting that the joint is provided with step circle.
The diameter of the quarter butt on bar and the valve block is consistent, and greater than the step diameter of a circle.
5Cr21Mn9Ni4N is adopted at bimetal valve valve block of the present utility model 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 said structural representation of the present utility model
1 is the valve block of band quarter butt among the figure, the 2nd, and bar.
Embodiment
The valve block 1 of bar 2 and band quarter butt adopts friction-welding technique to be welded as a whole, and carries out surface Machining again, processes step circle in the joint.
Valve block 1 adopts 5Cr21Mn9Ni4N, it has high temperature resistant, corrosion-resistant and impact-resistant performance, bar 2 adopts 4Cr9Si2, 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.
Claims (2)
1, a kind of valve comprises it is characterized in that the valve block of bar and boom end, and it is that valve block by bar and band quarter butt is formed by fixedly connecting, and the joint is provided with step circle.
2, a kind of valve according to claim 1 is characterized in that, the diameter of the quarter butt on bar and the valve block is consistent, and greater than the step diameter of a circle.
