Beschreibung
Zusammenfassung:	The utility model discloses a flat-bottom flange, and relates to the technical field of flanges. The flat-bottom flange comprises a first flange body and a second flange body, connecting through holes used for being connected with a pipeline are formed in the first flange body and the second flange body respectively, and a sealing gasket is fixedly connected to the side, opposite to the first flange body, of the second flange body. A sealing groove matched with the sealing gasket is formed in the side, opposite to the second flange, of the first flange, a connecting bolt is arranged on the first flange, a rotating groove is formed in the surface of the second flange, and a fixing mechanism is arranged in the rotating groove. According to the flat-bottom flange, it is ensured that the connecting bolt and the nut cannot be loosened, then the connecting effect of the first flange and the second flange is ensured, the sealing effect between two pipelines is ensured, the leakage phenomenon generated when liquid is
