Abstract
The utility model relates to a cylinder head gasket for an internal combustion engine or an air compressor, particularly a built-in ring type cylinder head gasket. The utility model is composed of a gasket and a metal ring, wherein, the metal ring is arranged at the inner side of an inner hole of the gasket; a circular engaging groove and a circular engaging tooth which can be engaged with each other are arranged between the gasket and the metal ring. The utility model has the advantages that good sealing performance is ensured, and simultaneously, the service life of the gasket is extended, and has the advantages of no cracking, no deformation, no corrosion, oil resistance and temperature resistance.
Description
Technical field
The utility model relates to a kind of cylinder head gasket, particularly a kind of built-in ring type cylinder head gasket of sealing between cylinder block and the cylinder cap of being used for.
Background technique
At present, seal the pad that is adopted between the cylinder body of domestic and international various cylinders and the cylinder cap, its structure is generally composite structure, also promptly inserts and puts asbestos material between two metal copper sheets and is composited.The cylinder head gasket of this structure in use, gasket surface occurring through regular meeting is that copper sheet is broken through, inner asbestos explosion, surface gas leakage, perishable distortion, working life is short, needs often to change, and when useless, useless power, influences work, and is unfavorable for reclaiming and uses.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of failure by rupture that is difficult for, the built-in ring type cylinder head gasket of long service life.
The technical solution of the utility model is made of pad and metal ring, and metal ring is located at the inboard of circular hole in the pad.
Be respectively equipped with on the inner circumference of circular hole and on the excircle of metal ring in the pad can intermeshing circular arc engaging groove, engaging tooth.
The utility model has the advantages that, when guaranteeing to have good seal performance, improved the life-span of using, and do not broken, indeformable, do not corrode oil resistant, heatproof.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Specific embodiment
The utility model embodiment is made of pad 1 and metal ring 2, and metal ring 2 is located at the inboard of circular hole in the pad 1.The material of pad 1 can be common asbestos material and once is stamped to form, and metal ring 2 can be copper material and is stamped to form.Because of the material of pad 1 is to have compressible soft asbestos material, so the thickness of asbestos washer 1 was a bit larger tham the thickness of metal ring 2 before assembling was used usually, with guarantee assembling use in the sealability of cylinder and cylinder head.Pad 1 shown in Figure 2 is consistent with the height of metal ring 2, that is to say the schematic representation of the utility model in assembling is used
For improving the mutual reliability of pad 1 and metal ring 2, in the pad 1 on the inner circumference of circular hole and be respectively equipped with on the excircle of metal ring 2 can intermeshing circular arc engaging groove and engaging tooth 3.
Claims (2)
1, built-in ring type cylinder head gasket is characterized in that: be made of pad and metal ring, metal ring is located at the inboard of circular hole in the pad.
2, built-in ring type cylinder head gasket as claimed in claim 1 is characterized in that: be respectively equipped with on the inner circumference of circular hole and on the excircle of metal ring in the pad can intermeshing circular arc engaging groove, engaging tooth.
