Abstract
The invention discloses an exhaust pipe gasket. The exhaust pipe gasket comprises a gasket body, wherein the gasket body is provided with three circular exhaust holes which are arranged side by side; the lower edge of each exhaust hole protrudes downwards; the gasket body on the right side of each exhaust ole is provided with strip-shaped tappet holes; the gasket body on the right side of each tappet hole is provided with a water hole; the gasket body between two adjacent rows of exhaust holes is provided with an oil hole respectively; the inner walls of the exhaust holes and the strip-shaped tappet holes are provided with asbestos pad layers respectively; the left end of the gasket body is leftwards provided with an arc-shaped flange; a mounting hole is formed in the arc-shaped flange. The gasket has a novel structure; the exhaust holes, the tappet holes and the water holes are formed in groups so as to be easy to distinguish; the asbestos pad layers on the inner walls of the exhaust holes and the tappet holes enhance the wear resistance and the sealing performance and prolong the service life.
Description
Technical field
The present invention relates generally to pad field, particularly relates to one and stablizes wear-resisting exhaust pipe pad.
Background technique
Pad (gasket) is the mechanical seal between two objects, usually to be under pressure between prevent two objects, burn into and pipeline expand with heat and contract with cold leakage naturally.Because machining surface can not be perfect, pad is used to fill up irreqularity.Be generally that a shim body has multiple hole in prior art, manufacturing process is complicated.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides one to stablize wear-resisting exhaust pipe pad.
The present invention is achieved by the following technical solutions:
One stablizes wear-resisting exhaust pipe pad, include shim body, it is characterized in that: shim body is provided with three square exhaust ports be arranged side by side, the inwall of each exhaust port is respectively equipped with heavy limit, the inwall on heavy limit is coated with silicone rubber wearing layer, shim body between adjacent two exhaust ports is provided with a heavy limit mounting hole, the shim body edge of the upper end of a heavy limit mounting hole and the lower end of another heavy limit mounting hole is provided with a pair lip limit respectively to extension, lip is provided with positioning hole in limit, the two end part of shim body are respectively equipped with an insulation projection, positioning hole is provided with in insulation projection.
Advantage of the present invention is:
Exhaust port of the present invention is provided with heavy limit, enhances sealability, and silicone rubber wearing layer also has good protection to exhaust port, makes the wear-resisting good stability of the present invention, lip limit be convenient to the present invention and other pad with the use of, further enhancing stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, one stablizes wear-resisting exhaust pipe pad, include shim body 1, shim body 1 is provided with three square exhaust ports 2 be arranged side by side, the inwall of each exhaust port 2 is respectively equipped with heavy limit 3, the inwall on heavy limit 3 is coated with silicone rubber wearing layer 4, shim body 1 between adjacent two exhaust ports 2 is provided with a heavy limit mounting hole 5, shim body 1 edge of the upper end of a heavy limit mounting hole 5 and the lower end of another heavy limit mounting hole 5 is provided with a pair lip limit 6 respectively to extension, positioning hole 7 is provided with in lip limit 6, the two end part of shim body 1 are respectively equipped with an insulation protruding 8, positioning hole 9 is provided with in insulation protruding 8.
