Abstract

The invention relates to the technical field of flanges, and discloses a sealing leakproof flange which comprises a first flange piece and a second flange piece. Nuts are fixedly connected to the left side and the right side of the lower surface of the first flange piece; fixing assemblies are arranged at the positions, located outside the nuts, of the left side and the right side of the lower surface of the first flange piece; and a sealing assembly is jointly arranged in the first flange piece and the second flange piece. According to the sealing leakproof flange provided by the invention, the fixing assemblies are arranged, positioning blocks in the fixing assemblies are clamped in a bolt to fix the bolt, and two second moving blocks are clamped on the two sides of the bolt to fix the bolt, so that the situation that the bolt is loosened and is not firm is avoided through the two fixing modes; and a first magnetic block in a sealing assembly attracts a second magnetic block, then a first sealing strip and a second sealing strip are matched to jointly achieve the sealing effect, a first angular layer is matched with a second angular layer, and then a first spring and a second spring are matched, so that the influence of vibration on the sealing effect can be avoided, and the excellent sealing and leakage preventing functions are achieved.

Description

technical field [0001] The invention relates to the technical field of flanges, in particular to a sealed and anti-leakage flange. Background technique [0002] Flanges are also called flange flanges or flanges. Flanges are parts that are connected to each other between pipes. They are used for connection between pipe ends, and some are used for equipment inlets and outlets. [0003] However, the existing flanges cannot prevent the bolts from loosening so that the installation between the flanges is not firm, and the existing flanges do not have an excellent anti-leakage function. Therefore, those skilled in the art provide a sealed and anti-leakage flange to solve the problems raised in the background art above. Contents of the invention [0004] The object of the present invention is to provide a sealed and anti-leakage flange to solve the problems raised in the above-mentioned background technology. [0005] To achieve the above object, the present invention provides ...
