Technical Field
The utility model relates to the technical field of rubber sealing, in particular to a flange sealing gasket.
Background
The sealing gasket is used for sealing machines, equipment and pipelines, and is a sealing spare part for places where fluid exists. Gaskets are typically used between flanges, and when two flanges are joined, the flanges corrode due to the galvanic corrosion between the dissimilar metals, thus requiring the use of flange gaskets for insulating the two flanges.
When the existing flange sealing gasket is used, the positions of the fixing bolt holes are not fixed firmly, so that gaps exist between adjacent flange plates, and the normal use of the flange is affected.
For this purpose, we propose a flange gasket to solve the above problems.
