Abstract
The utility model provides a kind of effective gasket seal of engine exhaust.The effective gasket seal of the engine exhaust, including metallic matrix, the metallic matrix center is provided with steam vent, the metallic matrix left and right side correspondence position is designed with the mounting hole with positioning tooth, the upper and lower side in periphery of the steam vent is designed with annular projection, in side, the corresponding opposite side of bossing is ring-type circular groove, and the upper and lower surface of the metallic matrix is all bonded with seal coating.The above-mentioned effective gasket seal of engine exhaust, because there is arc-shaped convex both sides, when using, bossing is pressed, and is brought into close contact with sealing surface, good sealing effect；Further, since being provided with the mounting hole with positioning tooth, occurs pressure inclined failure when can effectively prevent exhaust pipe pad from installing, and facilitate operative.
Description
Technical field
The utility model is related to exhaust pipe of engine apparatus field, more particularly to a kind of effective sealing gasket of engine exhaust
Piece.
Background technology
The Main Function of exhaust pipe of engine gasket seal be sealing, cylinder under high temperature, the working environment of high pressure, with
Under oil, aqueous corrosion atmosphere, the sealing function of pad is extremely important.Blast pipe and cylinder exist when the exhaust pipe of engine is connected with cylinder
There is deviation in flatness, another effect of exhaust pipe seal gasket piece is compensation deviation.Gasket seal master in the market
To be made using asbestos packing sheet, its defect is that the material is also easy to produce harmful exhaust, and service life ratio under hot operation
It is shorter.
Utility model content
Based on this, it is necessary to provide a kind of sealing effectiveness effective gasket seal of preferable engine exhaust.
A kind of effective gasket seal of engine exhaust, including metallic matrix, the metallic matrix center are provided with steam vent, institute
State metallic matrix left and right side correspondence position and be designed with the mounting hole with positioning tooth, the upper and lower side in periphery of the steam vent all sets
There is annular projection, the corresponding opposite side of bossing is ring-type circular groove, the upper and lower surface of the metallic matrix in side
All it is bonded with seal coating；The material of the seal coating is nitrile rubber；The height of the annular projection is the engine
Blast pipe is with 1~2 times of gasket seal thickness.
The above-mentioned effective gasket seal of engine exhaust, because there is arc-shaped convex both sides, when using, bossing is pressed
System, is brought into close contact, good sealing effect with sealing surface；Further, since being provided with the mounting hole with positioning tooth, exhaust can be effectively prevented
Occur pressure inclined failure when pipe pad is installed, and facilitate operative.
Brief description of the drawings
Fig. 1 is the structural representation of the effective gasket seal of engine exhaust of the present utility model；
Fig. 2 is the sectional view of Fig. 1；
In figure, 1- metallic matrixes, 2- steam vents, 3- mounting holes, 4- annular protrusions, 5- toroidal cavities, 6- seal coatings.
Specific embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to protection domain of the present utility model
Define.
Fig. 1~2, a kind of effective gasket seal of engine exhaust, including metallic matrix 1 are referred to, the center of metallic matrix 1 sets
There is steam vent 2, the left and right side correspondence position of metallic matrix 1 is designed with the mounting hole 3 with positioning tooth, on the periphery of steam vent 2,
Downside is designed with annular projection 4, and in side, the corresponding opposite side of bossing is ring-type circular groove 5, metallic matrix 1
Upper and lower surface is all bonded with seal coating 6.The inner circle of above-mentioned mounting hole 3 is uniformly arranged three positioning tooths of triangle, can be effective
Occur pressure inclined failure when preventing exhaust pipe pad from installing, and facilitate operative.
Wherein, the material of seal coating 6 is nitrile rubber.Due to being coated with seal coating 6, good sealing effect is can reach
Really.
The height of annular projection is 1~2 times of the effective gasket seal thickness of engine exhaust.
The above-mentioned effective gasket seal of engine exhaust, because there is arc-shaped convex both sides, when using, bossing is pressed
System, is brought into close contact, good sealing effect with sealing surface；Further, since being provided with the mounting hole with positioning tooth, exhaust can be effectively prevented
Occur pressure inclined failure when pipe pad is installed, and facilitate operative.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore can not be interpreted as the limitation to the utility model the scope of the claims.It should be pointed out that common for this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
