[0003] After searching, the patent with the authorization announcement number CN207112161U proposes a flange sealing structure, which involves the field of equipment sealing technology. By setting a sealing gasket on the sealing surface between the upper sealing ring and the lower sealing ring, the sealing of the internal gap between the upper sealing ring and the lower sealing ring is achieved; by setting a welding ring on the outer circumference of the integral sealing ring formed by the upper sealing ring and the lower sealing ring, the sealing of the external gap between the upper sealing ring and the lower sealing ring is achieved, thereby achieving double sealing of the flange connection structure, thereby ensuring the long-term safe operation of the flange equipment. The following problems exist in this technical solution:

[0004] When in use, the two flanges can be connected by the provided fasteners. Since it is not convenient to quickly position and match the two flanges during connection, multiple threaded holes on the two flanges need to be matched one by one by rotating the flanges during the connection and fixing process, which is not only inconvenient for users to operate and fix, but also reduces the connection efficiency;
