Abstract
The utility model belongs to the technical field of cylinder head seals of diesel motor, and relates to a cylinder head gasket of a diesel motor. At least one annular convex ring is arranged on one end face of the gasket; and at least two semi-circular openings are formed on the outer cylindrical surface of the gasket. The cylinder head gasket has the advantages of simple structure and accurate location, and can improve the efficiency and reduce the emission.
Description
Technical field
The utility model belongs to diesel generator cylinder end seal part technical field, refers in particular to a kind of diesel generator cylinder head pad.
Background technique
The sealing gasket that is provided with between the cylinder body of existing diesel generator and the cylinder cap is generally an annular copper packing ring, be fixed by cylinder cap, but the vibrations that piston motion causes make the sealing gasket sideslip easily, the position of causing sealing gasket and cylinder is not on the same center of circle, the uneven homogenize in the gap that cylinder liner caused when cylinder and cylinder cap were cooperated, when having increased expansion stroke since when only burning flame cancellation that the gap causes and exhaust the waste gas in dark gap, limit discharge difficulty, increased the content of waste gas in second inflammable mixture that sucks, reduce efficient, increased discharging.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and accurate positioning can increase efficient, reduces a kind of diesel generator cylinder head pad of discharging.
The purpose of this utility model is achieved in that
Diesel generator cylinder head pad is provided with a circle annular convex ring at least on one end face of pad, be provided with two semicircle openings on the external cylindrical surface of pad at least.
Annular convex ring on the above-mentioned pad has two.
Semicircle opening on the above-mentioned pad has two.
Above-mentioned pad is made of copper product.
The outstanding compared to existing technology advantage of the utility model is:
Annular convex ring on the pad of the present utility model cooperates with the scrobicular ring that ring rib on the upper-end surface that cylinder head cover contacts forms, semicircle opening on the pad cooperates with locating stud, pad stably can be positioned between cylinder body and the cylinder cap, be difficult for making the loosening skew of gasket seal, gap homogenization when cylinder and cylinder cap are cooperated between the cylinder liner, when having reduced expansion stroke since when only burning flame cancellation that the gap causes and exhaust the waste gas in dark gap, limit discharge difficulty, reduced the content of waste gas in second inflammable mixture that sucks, increase efficient, reduced discharging.

Exploded perspective view when Fig. 1 is the utility model application;
Fig. 2 is a plan view of the present utility model;
Fig. 3 is a sectional view of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-3:
Diesel generator cylinder head pad, between the cylinder body 10 of diesel generator cylinder and cylinder cap 20, be provided with ring packing pad 30, at least be provided with a circle annular convex ring 31 on one end face of pad 30, on the external cylindrical surface of pad 30, be provided with two semicircle openings 32 at least.
Semicircle opening 32 on the above-mentioned pad 30 has two.
Above-mentioned pad 30 usefulness copper products are made.
Described pad 30 cooperates two annular grooves 21 on the cylinder head cover 20 to install and be fixed between cylinder body 10 and the cylinder head cover 20 with locating stud 40.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection domain of the present utility model according to this; so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
