Abstract:
A flange (11), a sealing method therefor and an insulator using the flange (11), relating to the technical field of flanges. The flange (11) comprises: a groove (15) formed at one side of the flange (11), the bottom of the groove (15) being provided with a first through hole (16) for inflating; an inflating valve (13) provided in the groove (15); and a sealing member (14) that wraps an end face, facing an opening of the groove (15), of the inflating valve (13) and is filled between the inflating valve (13) and the inner wall of the groove (15). The sealing member (14) directly wraps the end face, facing the opening of the groove (15), of the inflating valve (13), and is filled between the inflating valve (13) and the inner wall of the groove (15), thereby filling a slit between the inflating valve (13) and the flange (11), preventing penetration of steam outside the flange (11) into the flange (11) through the slit between the inflating valve (13) and the sealing member (14), blocking a steam penetration path between the inflating valve (13) and the sealing member (14), improving airtightness of an inflating valve (13) area in the flange (11), improving the service life and use reliability of a product, and ensuring insulating performance and electrical performance of the product.
