Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a flange for a mine drainage pipe which can be quickly disassembled. Background Art

[0002] Flange, also known as flange plate or flange, is used to connect sleeve pipes. Holes are set on the existing flanges, and the two flanges are fastened and connected by bolts. The flanges are sealed with gaskets. Flange is a disc-shaped part, which is most common in pipeline engineering. Flanges are used in pairs. In drainage engineering, flanges are mainly used for pipe connection.

[0003] Since existing flanges are provided with multiple holes, multiple bolts need to be inserted between the flanges and the nuts on all the bolts need to be tightened. The installation is time-consuming and labor-intensive, and the disassembly is inconvenient, resulting in low disassembly efficiency of mine drainage pipes and increased labor for workers.

[0004] In order to solve the above problems, we proposed a flange for mine drainage pipes which can be quickly disassembled. Utility Model Content

[0008] In the above-mentioned quickly detachable flange for mining drainage pipes, the connecting sleeve has a thin-wall feature, and an annular positioning groove is provided on the rear end outer wall of the connecting sleeve.

[0009] In the above-mentioned quickly detachable flange for mining drainage pipes, a plurality of reinforcing plates are fixedly provided on the rear side wall of the fixing ring, and the ends of the reinforcing plates are fixedly connected to the outer wall of the connecting sleeve.

[0010] In the above-mentioned quickly detachable flange for mining drainage pipes, the diameters of the threaded hole 1 and the through hole 2 are smaller than the diameters of the through hole 1 and the threaded hole 2.
