Abstract
The invention discloses a vehicle engine valve. The vehicle engine valve is characterized by comprising a valve head and a valve rod which are combined, wherein the valve head is connected with the valve rod; the valve head is in a shape of a flat top, the valve head is made of alloy steel, the valve rod is in a cylindrical shape, and the valve rod is made of heat resistant alloy; the cone angle of the valve is 30 degrees to 45 degrees. In the mode, the strength, rigidity and heat resistant and wear resistant performances of the valve can be increased.
Description
Technical field
The present invention relates to auto parts and components field, particularly relate to a kind of vehicular engine valve.
Background technique
The effect of valve is responsible for input air in motor specially and discharges the waste gas after burning.From engine structure, be divided into intake valve (intakevalve) and exhaust valve (exhaustvalve).The effect of intake valve is by air intake motor, burns with fuel mix; The effect of exhaust valve be by burning after waste gas discharge and dispel the heat.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of vehicular engine valve, can improve the intensity of valve, rigidity, heat-resisting and wear-resisting property.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of vehicular engine valve, it is characterized in that, comprising: valve head and valve stem combine, wherein, described valve head is connected with described valve stem; Described valve head shape is flat-top, and described valve head material is alloyed steel, and described valve stem is cylindrical, and material is heat resisting alloy; Described valve cone angle is 30 °-45 °.
In a preferred embodiment of the present invention, the Placement of described valve head and described valve stem phase is for welding.
In a preferred embodiment of the present invention, the described described each composition of valve head material alloys steel and proportioning are: carbon steel 32%-45%, chromium 10%-15%, molybdenum 12%-15%, tungsten 18%-20%, vanadium 15%-18%.
