Abstract
The utility model relates to a high-temperature resistant and energy-saving head gasket comprising a head gasket body and corresponding cylinder holes, water holes, tappet holes and oil holes, which are arranged in the head gasket body. The high-temperature resistant and energy-saving head gasket is characterized in that the head gasket body comprises an upper metal gasket and a lower metal gasket, a punched galvanized steel strip used as a coreboard is clamped between the metal gaskets, ring full-wave ripples are arranged in the metal gaskets along the cylinder holes, the water holes, the tappet holes and the oil holes, the cylinder holes, the water holes, the tappet holes and the oil holes are connected with the head gasket body in a spot welding or inlaid way, and oil-resistant rubber rings are arranged at the inner sides of the holes. The high-temperature resistant and energy-saving head gasket disclosed by the utility model has high thermal resistance and corrosion resistance and is capable of effectively ensuring leak tightness of an oil cylinder in the running process.
Description
Technical field
The utility model relates to internal combustion engine component, is specially a kind of high-temperature resistance energy-saving head gasket.
Background technique
In internal-combustion engine, head gasket is interposed on the junction plane between the cylinder block and head also fastened, thereby plays seal action.The traditional air cylinder pad is to be composited by clamping asbestos slate or two-layer asbestos slate therebetween layer of metal spurt plate in the middle of two metallic shims, and this pad is very easy to damage, and working life is short, and assembling and dissembling process is easy to generate environmental pollution, is unfavorable for environmental protection.And along with continually strengthening of internal-combustion engine, heat load and mechanical load all constantly increase, and the sealing of head gasket is more and more important, to structure and material require increasingly highly, thereby the traditional air cylinder pad also more and more is not suitable for present use.
The model utility content
The technical problem that the utility model solved is to provide a kind of high-temperature resistance energy-saving head gasket, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technological scheme to realize:
A kind of high-temperature resistance energy-saving head gasket; Comprise corresponding cylinder hole, water hole, tappet bore and oilhole on pad and the pad; Said pad comprises upper and lower two metallic shims; Accompany one in the middle of the metallic shim and have the spurt Galvanized Steel Strip as central layer, simultaneously, upper and lower metallic shim is provided with ring-type all-wave line along the cylinder-bore on it, water hole, tappet bore and oilhole.
In the utility model, cylinder-bore, water hole, tappet bore and oilhole and pad are connected through the spot welding or the mode of inlaying, and the inboard, hole is provided with oil-resistant rubber ring.
In the utility model, said spurt Galvanized Steel Strip, upper surface and lower surface are staggeredly equipped with the maintenance tooth.
Beneficial effect: the utility model is simple in structure, and is easy to process, widely applicable; High temperature resistant; Corrosion-resistant, and can make internal-combustion engine be issued to good sealing effect at high temperature, high pressure, solved little infiltration problem of internal-combustion engine; Not towards cylinder, air tight, water-tight, oil-proof, can effectively improve the reliability and the durability of internal-combustion engine.
Description of drawings
Fig. 1 is the schematic representation of the utility model preferred embodiment.
Fig. 2 is the pad section detailed drawing of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to a kind of high-temperature resistance energy-saving head gasket of Fig. 1; In the present embodiment; Metallic shim on the head gasket is formed by upper and lower two; Upper and lower metallic shim 1, the cylinder-bore on 2 along its 4, water hole 5, tappet bore 6 and oilhole 7 peripheries are respectively equipped with the annular resilient ripple, and also are with oil-resistant rubber ring at each bore edges periphery.
Referring to the A-A schematic cross-section of the preferable enforcement of the novel head gasket of Fig. 2, can see that pad comprises upper metallic gasket 1, metallic shim 2 down, simultaneously, also is provided with one and has the Galvanized Steel Strip 3 of making a spurt between upper metallic gasket 1 and following metallic shim 2.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model protection defined by the appended claims and their equivalents defined
.
