Rubber gasket

Abstract

The invention discloses a rubber gasket. The rubber gasket comprises an annular gasket body, wherein the gasket body comprises a first gasket, a second gasket which is positioned at the inner side ofthe first gasket, and an intermediate ring body for connecting the first gasket and the second gasket; a plurality of groups of outer ring holes are uniformly formed around a central axis of the gasket body on the first gasket; each group of outer ring holes includes a first fixing hole in which a bolt penetrates, and a first positioning hole for positioning; the centers of the first fixing holesand the centers of the first positioning holes are on the same circle; a plurality of groups of inner ring holes are uniformly formed around the central axis of the gasket body on the second gasket; each group of inner ring holes include a second fixing hole in which a bolt penetrates, and a second positioning hole for positioning; and the centers of the second fixing holes and the centers of thesecond positioning holes are on the same circle. With the adoption of the rubber gasket, the frequency of adjusting in mounting can be effectively decreased; and the working efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a rubber gasket. Background technique [0002] In order to ensure the tightness between the two parts, gaskets of different specifications are usually set between the two parts. These gaskets not only have different styles, but also have various materials, such as metal, fiber, rubber, plastic, and various A mix of materials, these gaskets guarantee a tight seal between the two components. In some structures, due to the large contact surface, it is necessary to form two seals on the outer and inner edges between the two parts. The current conventional practice is to install two corresponding gaskets on the sealing surfaces of the two parts respectively. The outer edge and inner edge of the two gaskets need to be positioned accurately during installation to ensure that the bolts can just pass through the through holes on the gasket. The gasket located on the outer edge can be positioned more accurately, while the gasket located...

In some structures, due to the large contact surface, it is necessary to form two seals on the outer and inner edges between the two parts. The current conventional practice is to install two corresponding gaskets on the sealing surfaces of the two parts respectively. The outer edge and inner edge of the two gaskets need to be positioned accurately during installation to ensure that the bolts can just pass through the through holes on the gasket. The gasket located on the outer edge can be positioned more accurately, while the gasket located on the inner edge Due to the narrow operating space of the shim, the position adjustment of the shim is greatly restricted, and it often takes several times to adjust it in place, which not only increases the working time and work intensity of the installer, but also affects the installation quality to a certain extent.
