Embodiment 1
Referring to figs. 1 to Fig. 3, it is a kind of Pipe installing nozzle centering corrector provided in this embodiment in figure, is directed to
The case where 11 misalignment of nozzle being commonly encountered in turbine unit, there are misalignments, leads to not normal weld or influences welding matter
The problem of amount, after the fixed school shape of flange, while being welded as welding tooling.
Specifically, Pipe installing nozzle centering corrector includes mounting flange, the first fastening screw group 31 and the second top
Tight screw rod group 32;Mounting flange is sheathed on the outer peripheral surface of tube body 10, and mounting flange includes the first method of separable cooperation
Orchid 21 and second flange 22.When in use, first flange 21 and second flange 22 are matched, composition has consolidating for circular contour
Determine flange.First fastening screw group 31 and the second fastening screw group 32 respectively along mounting flange cross-wise direction pass through mounting flange with
Tube body 10 abuts;First fastening screw group 31 and the second fastening screw group 32 are corresponding with 11 two sides of nozzle of tube body 10 respectively.Gu
Determine flange and enclose 10 outer peripheral surface of tube body for being set to and needing school shape, is distinguished by the first fastening screw group 31 and the second fastening screw group 32
The tube body 10 at 11 both ends of line up is adjusted, and realizes the centering of school shape.
Using being threadedly engaged for above-mentioned first fastening screw group 31 and the second fastening screw group 32 and mounting flange, will rotate
It is converted into movement of the screw rod to 10 center of circle direction of tube body, realizes the adaptation to each size pipeline.
In specifically used, the offset direction of tube body 10 is different, for the ease of being adjusted to tube body 10, at this
In embodiment, the first fastening screw group 31 and the second fastening screw group 32 respectively include three fastening screws.It is held out against using three
Self-centering may be implemented in screw rod, the concentricity of the tube body 10 after guaranteeing school shape.
Further, for the ease of the cooperation between fastening screw and mounting flange, fastening screw passes through mounting flange
