Abstract
The utility model discloses a mechanical sealing gasket, comprising a gasket body, which has a two-layer structure, comprising a sealing layer and a joint layer from top to bottom. The upper surface of the gasket body is provided an annular projection and the lower surface of the gasket body is provided with an annular groove corresponding to the projection. With the gasket body having the two-layer structure, the mechanical sealing gasket realizes better joint with and sealing of a component. With the upper surface of the gasket body being provided with the annular projection and the lower surface of the gasket body being provided with the annular groove corresponding to the projection, the mechanical sealing gasket, when being used, enables the projection to be pressed flat and thus to be further jointed with a sealing surface tightly.
Description
Technical field
The utility model relates to a kind of mechanical part, especially a kind of mechanical seal packing ring.
Background technique
The joint seal request of engine exhaust pipe and pressurized machine is high, and temperature is also very high.In the existing technology, generally adopt with the expanded graphite composite sheet this joint is the ring packing pad of a kind of surfacing of material, and its deficiency is when gas temperature acquires a certain degree, and sealing effect can be affected, and has increased maintenance cost simultaneously.
The model utility content
To the problem that above-mentioned existing technology exists, the utility model provides a kind of mechanical seal packing ring.
To achieve these goals, the technological scheme of the utility model employing is: a kind of mechanical seal packing ring comprises circle body; Circle body is a double-layer structure; Be followed successively by sealing layer and laminating layer from top to bottom, the upper surface of circle body is provided with the convexity of ring-type, and lower surface is provided with the groove of protruding corresponding cyclic.
As preferably, sealing layer is identical with the laminating layer size and overlap fully.
As preferably, circle body is a ring.
Compared with prior art, the advantage of the utility model is: circle body is a double-layer structure, better parts is fitted and seals; The upper surface of circle body is provided with the convexity of ring-type, and lower surface is provided with the groove of protruding corresponding cyclic, during use; Convexity is driven plain, and further fits tightly with sealing surface.
Description of drawings
Fig. 1 is the sectional view of the utility model;
Fig. 2 is the worm's eye view of the utility model.
Among the figure: 11, sealing layer; 12, laminating layer; 21, convexity; 22, groove.
Embodiment
To combine accompanying drawing that the utility model is described further below.
A kind of mode of execution as the utility model; Consult Fig. 1 and Fig. 2; The utility model comprises the circle body of ring, and circle body is a double-layer structure, is followed successively by sealing layer 11 and laminating layer 12 from top to bottom; The upper surface of circle body is provided with the convexity 21 of ring-type, and lower surface is provided with the groove 22 of protruding 21 corresponding cyclic.Sealing layer 11 and fully coincidence identical with laminating layer 12 sizes.
During use, the upper surface of circle body is provided with the convexity 21 of ring-type, and lower surface is provided with the groove 22 of protruding 21 corresponding cyclic, and protruding 21 are driven plain, and further fit tightly with sealing surface.And circle body is a double-layer structure, better parts is fitted and seals.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation in spirit that does not break away from the utility model or the scope in other embodiments among this paper.Therefore, the utility model will can not be limited to these embodiments shown in this paper, but will accord with principle disclosed herein and features of novelty the wideest corresponding to scope.
