Abstract
The utility model relates to the technical field of automobile spare parts, in particular to a valve seat ring of an engine. The novel valve seat ring comprises a valve seat bottom ring and a valve seat surface layer, wherein the valve seat bottom ring and two end faces of the valve seat surface layer are tightly attached and connected to form a whole, and the inner diameter and the outer diameter of the valve seat bottom ring and the inner diameter and the outer diameter of the valve seat surface layer are the same. The novel valve seat ring is simple in structure, and meets the engine valve mechanism operating conditions of high temperature, high pressure, and high impact force. At the same time, the cost of the valve seat ring is reduced, and comprehensive economical efficiency is improved.
Description
Technical field
The utility model relates to the auto parts machinery technical field, especially a kind of air valve seat ring of motor.
Background technique
At present, traditional valve retainer for automobile engine is a kind of overall structure of material.Engine valve and valve seat work under bad environment will be born high temperature, high pressure and impact force, and requiring again has quite long working life, therefore adopt good heat resistant and wear resistant to decrease material, and cost rises.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, provide a kind of simple in structure, the air valve seat ring that cost is low.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of Novel valve seat ring, have valve seat foundation ring and valve seat top layer, described valve seat foundation ring and valve seat top layer both ends of the surface fit tightly and are connected to an integral body, and the internal diameter on valve seat foundation ring and valve seat top layer and external diameter equate.
Further, described valve seat foundation ring and valve seat top layer separately after minute chamber moulding pressure sintering be integrated.
The beneficial effects of the utility model are: the utility model is simple in structure, can satisfy high temperature, the high pressure of engine air valve device, the operating conditions of high impact forces, reduces simultaneously the cost of air valve seat ring, and comprehensive economy is improved.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is sectional view of the present utility model.
1. valve seat foundation rings, 2. valve seat top layer among the figure.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
Novel valve seat ring as shown in Figure 1 has valve seat foundation ring 1 and valve seat top layer 2, and valve seat foundation ring 1 and valve seat top layer 2 both ends of the surface fit tightly and are connected to an integral body, and the internal diameter on valve seat foundation ring 1 and valve seat top layer 2 and external diameter equate; Valve seat foundation ring 1 and valve seat top layer 2 separately after minute chamber moulding pressure sintering be integrated.
This Novel valve seat ring is simple in structure, can satisfy high temperature, the high pressure of engine air valve device, the operating conditions of high impact forces, reduces simultaneously the cost of air valve seat ring, and comprehensive economy is improved.
Above-mentioned mode of execution only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection domain of the present utility model.
