Pipeline butt joint device for municipal water supply and drainage

The utility model discloses a municipal water supply and drainage pipeline butt joint device which comprises a first flange plate, threaded sleeves are evenly installed at one end of the first flange plate, the interiors of the threaded sleeves are connected with threaded rods through threads, and one ends of the threaded rods are rotationally connected with a second flange plate. One end of the first flange plate and one end of the second flange plate are respectively provided with an inserting pipe, one end of the second flange plate is provided with a synchronous rotation positioning mechanism, and compared with the prior art, through the synchronous rotation positioning mechanism, the threaded rod connecting device has the advantages that synchronous rotation of a plurality of threaded rods can be facilitated, the synchronous rotation difficulty of the threaded rods is reduced, and the machining efficiency is improved. And meanwhile, the phenomenon that when the multiple threaded rods rotate independently
