Abstract
The invention discloses a cylinder head gasket structure of a diesel engine. The cylinder head gasket structure comprises a gasket body. Cylinder holes are distributed in the gasket body. Water holes are formed between the cylinder holes. Mounting holes, locating holes and tappet holes are formed outside the water holes. The edges of the cylinder holes are coated with black butyronitrile rubber layers, arc-shaped sealing lugs which protrude outwards are arranged on one sides of the black butyronitrile rubber layers, the edges of the water holes, the edges of the mounting holes, the edges of the locating holes and the edges of the tappet holes are coated with rubber layers respectively, anti-skidding protrusions are distributed at the edge of the gasket body, and a plurality of notches are formed in the two sides of the gasket body respectively. By the adoption of the cylinder head gasket structure, sealing performance is enhanced, and the cylinder head gasket structure is convenient to machine and manufacture and high in production efficiency; through distribution of the anti-skidding protrusions on the gasket body and the notches in the two sides of the gasket body, stability of a gasket in the mounting process is guaranteed.
Description
Technical field
The present invention relates to cylinder seal technical field, relate in particular to a kind of diesel engine cylinder mat structure.
Background technique
Existing diesel engine cylinder pad is the compound head gasket of structure of steel wire ring, comprise the head gasket body that metal and nonmetallic material are composited, on head gasket body, be provided with cylinder port, water oilhole, bolt hole, positioning hole, and the irrational distribution of water hole, tappet bore, mounting hole and positioning hole on existing cylinder gasket, thereby remote-effects its whole sealing.
Summary of the invention
The object of the invention is, in order to make up the deficiency of prior art, provides a kind of diesel engine cylinder mat structure.
The present invention is achieved through the following technical solutions:
A kind of diesel engine cylinder mat structure, include shim body, it is characterized in that: in described shim body, be distributed with cylinder-bore, between cylinder-bore, be provided with water hole, outside water hole, be provided with mounting hole, positioning hole and tappet bore, the edge of described cylinder-bore is coated with a circle black butyronitrile glue-line, and a side of black butyronitrile glue-line is provided with outwardly arc sealing ear, described water hole, mounting hole, positioning hole, the edge of tappet bore is coated with respectively rubber layer, the edge of described shim body is also distributed with anti-skidding projection, the both sides of described shim body are many places breach respectively.
Advantage of the present invention is:
The present invention is by the reasonable Arrangement of cylinder-bore, water hole, mounting hole, positioning hole, tappet bore, and the structural design of the rubber layer that applies of the black butyronitrile glue-line that applies of cylinder-bore place and water hole, mounting hole, positioning hole, tappet bore place, not only strengthened sealability, its convenient processing and manufacture of while, manufacturing efficiency is high, the distribution of the breach by the anti-skidding projection in shim body and its both sides, has guaranteed stability when pad is installed.
