W-shaped exhaust gasket structure

Abstract

The invention discloses a W-shaped exhaust gasket structure. The exhaust gasket structure comprises a gasket body. Exhaust ports which are distributed in a W-shaped mode are formed in the gasket body respectively. Arc-shaped sealing convex ribs which protrude outwards are arranged on the exhaust ports respectively. A kidney-shaped locating hole is formed between every two adjacent exhaust ports located in the bottom end of each W shape. Adjusting holes are formed above the kidney-shaped holes. Buffer convex ribs opposite to the arc-shaped sealing convex ribs are arranged on the adjusting holes. The outer edges of the buffer convex ribs are intersected with the arc-shaped sealing convex ribs. Mounting holes are distributed in the gasket body. The gasket body is designed into the W shapes matched with distribution of the exhaust ports, the shape structure of a traditional gasket is changed, and therefore the thrust face of a gasket is reduced; by the cooperation of the structure of the sealing convex ribs on the exhaust ports and the buffer convex ribs opposite to the sealing convex ribs and on the adjusting holes, the exhaust gasket has certain elasticity, can rapidly restore after being stressed, is not prone to being damaged after being used for a long term, and long in service life, use cost is reduced, and the using requirement is met.

Description

technical field [0001] The invention relates to the technical field of gasket structures, in particular to a W-shaped exhaust gasket structure. Background technique [0002] The exhaust pad is used to ensure a good seal between the parts and prevent the outside air from entering. The existing exhaust pad has a simple structure, and most of its bodies adopt a rectangular structure. According to the position of the exhaust port, there are corresponding openings on its position. If the exhaust port is removed, the rest of the body structure will not be removed, which will increase the stress surface of the gasket and affect its elasticity. When it is subjected to air pressure for a long time, it is difficult to recover, thereby reducing its The service life needs to be replaced frequently, which increases the cost of use. Contents of the invention [0003] The object of the present invention is to provide a W-shaped exhaust pad structure in order to make up for the deficienc...
