Flange connection or flange joint refers to a detachable connection in which flange, gasket and bolts are connected to each other as a combined sealing structure.

[0003] The Chinese patent application number CN202222365719.8 discloses a flange processing device for valve processing, including a device table. The utility model can clamp and fix flanges of different sizes through the cooperation of the first pneumatic cylinder, the support plate and the side fixed pressure plate, and the cooperation of the second pneumatic cylinder and the top fixed pressure plate. By arranging an adjustable positioning mechanism at the center position of the top wall inside the device table, flanges of different sizes can be positioned. By connecting the first rubber pad to the side of the side fixed pressure plate, connecting the second rubber pad to the lower surface of the top fixed pressure plate, and sleeved with a rubber sheath on the outer surface of the positioning column, the flange can be prevented from being damaged when the flange is positioned and fixed.
