[0032] Flange gasket is a sealing element located between two flanges to ensure the sealing between the two flanges. In terms of equipment, the gasket and the flange need to be at a certain concentricity, and the flange is tightened by tightening the bolts to ensure its sealing. At present, the common method of installing flange gaskets is mainly to adjust the position of the gasket by visual inspection using thin wire, a flat screwdriver or by hand, but the error is large and the concentricity between the gasket and the flange cannot be effectively guaranteed. During the installation process, the gasket will also be offset and cannot completely match the flange sealing surface. At the same time, it will affect the flow of the medium in the pipeline, the local pressure will fluctuate, and even the sealing effect of the flange will be greatly reduced, resulting in leakage of pipeline media during use, causing harm to people and equipment. In order to solve this technical problem, a flange gasket auxiliary installation device is proposed.
