Process pipeline with universal adjusting function

The utility model discloses a process pipeline with a universal adjusting function, relates to the technical field of pipelines, and solves the technical problems that an existing in-cabin on-site matched welding smoke exhaust pipeline is difficult to operate due to narrow space in a power cabin, and meanwhile, sparks generated in the matched welding process have potential safety hazards. Comprising a mounting plate, a spherical rod, a sleeve, a supporting block, a switching sealing plate, a straight cylinder, a bent cylinder, a compression bolt and a fastening bolt, the spherical rod is mounted in the sleeve, the supporting block is mounted in the sleeve and located below the spherical surface of the spherical rod, the supporting block is rotated to enable a key groove and a conical groove of the supporting block to be aligned with a threaded hole of the sleeve, and the compression bolt and an M6 fastening screw are mounted in the sleeve. An M5 screw is used for installing an adapter sealing plate to enable
