Abstract

The invention discloses an anti-seepage bonded washer. The anti-seepage bonded washer comprises a left washer body and a right washer body. The left washer body and the right washer body are both annular. The middle of the surface of the right washer body protrudes to be of a ringlike wedge-shaped structure. The surface of the left washer body is provided with a matched wedge-shaped groove relative to the wedge-shaped structure. The left washer body and the right washer body are both rubber washers. The surface of the wedge-shaped structure and the surface of the wedge-shaped groove are of a dull polish shape. The height of the wedge-shaped structure is half the thickness of the right washer body, and the depth of the wedge-shaped groove is half the thickness of the left washer body. As a whole, the anti-seepage bonded washer has a good anti-seepage effect.

Description

technical field [0001] The invention belongs to the technical field of gaskets, in particular to an anti-leakage composite gasket. Background technique [0002] Sealing gasket is a sealing spare part used in machinery, equipment, and pipelines as long as there is fluid. It uses internal and external materials to play a sealing role. It is often used for the sealed connection between pipelines, and the sealed connection between parts of machinery and equipment. In the prior art, in order to prevent leakage, the upper surface and the lower surface of the gasket body are coated with anti-leakage glue. Such a gasket has poor anti-leakage effect, which affects the requirement of high standards. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide an anti-leakage composite gasket that can meet the requirement of high anti-leakage performance. [0004] The object of the present invention is achieved...
