Abstract
The utility model discloses a cylinder gasket structure with good sealing performance, which comprises a gasket body. Cylinder holes are distributed on the gasket body; a ring-shaped groove is distributed on the outer periphery of each cylinder hole; mounting holes, waist-shaped positioning holes, water holes, tappet rod holes and screw thread holes are distributed on the peripheries of the cylinder holes; the upper end face of the gasket body in each screw thread hole is coated with a black butyronitrile adhesive layer; the water holes are coated with nylon plastic material sealing layers; the nylon plastic sealing layers are of a triangular or waist shape; and the outer peripheries of the tappet rod holes are coated with rubber layers. The cylinder gasket structure is convenient to process and manufacture and is low in manufacturing cost; by the black butyronitrile adhesive layers and the nylon plastic material sealing layers coated outside the water holes, the sealing performance of the cylinder gasket structure is reinforced, the cylinder gasket structure has good leakage-proof performance and the service life of the cylinder gasket structure is prolonged; and meanwhile, with the structural design of the shape of the nylon plastic material sealing layers outside the water holes, the cylinder gasket structure has a symmetrical and attractive integral structure.
Description
Technical field
The utility model relates to cylinder seal technical field, relates in particular to a kind of head gasket structure of good seal performance.
Background technique
Engine cylinder ring is the important seal fitting in motor car engine, is arranged between cylinder body and cylinder cap, plays seal action and prevents motor gas leakage, leaks and leakage of oil.The head gasket of motor is mainly constituted by stacked conducting plate at present, which is provided with cylinder mouth, positioning hole and oilhole, and the defect of existing product is that manufacture cost is higher, complex structure, and sealing effect is bad, and working life is short.
Model utility content
The purpose of this utility model is the deficiency in order to make up prior art, and a kind of head gasket structure of good seal performance is provided.
The utility model is achieved through the following technical solutions:
A kind of head gasket structure of good seal performance, include shim body, it is characterized in that: in described shim body, be distributed with cylinder-bore, the outer circumference of described cylinder-bore is distributed with annular groove, the circumferential distribution of described cylinder-bore has mounting hole, kidney-shaped positioning hole, water hole, tappet bore, tapped hole, on the upper-end surface of the shim body in described tapped hole, be coated with black butyronitrile glue-line, outside described water hole, be coated with nylon plastic material sealing layer, described Nylon sealing layer be shaped as triangle or kidney-shaped, described tappet bore outer periphery is coated with rubber layer.
The utility model has the advantages that:
The utility model reasonable in design, by the structure of individual layer shim body, its convenient processing and manufacture, low cost of manufacture, by black butyronitrile glue-line, outside water hole, be coated with the nylon plastic material sealing layer outside nylon plastic material sealing layer and water hole, it has strengthened its sealability, and leak resistance is good, has improved its working life, the structural design of simultaneously passing through the shape of the nylon plastic material sealing layer outside water hole, makes its overall structure symmetry, attractive in appearance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of head gasket structure of good seal performance, include shim body 1, in shim body 1, be distributed with cylinder-bore 2, the outer circumference of cylinder-bore 2 is distributed with annular groove 3, the circumferential distribution of cylinder-bore 2 has mounting hole 4, kidney-shaped positioning hole 5, water hole 6, tappet bore 7, tapped hole 8, on the upper-end surface of the shim body in tapped hole 8, be coated with black butyronitrile glue-line 9, the outer nylon plastic material sealing layer 10 that is coated with in water hole 6, Nylon sealing layer 10 be shaped as triangle or kidney-shaped, tappet bore 7 outer peripherys are coated with rubber layer 11.
