Pipeline expansion joint capable of achieving flexible compensation

Abstract

The utility model relates to the technical field of expansion joints, and discloses a pipeline expansion joint capable of realizing flexible compensation, which solves the problems that the existing expansion joint is unstable to place during storage and transportation, the expansion joint is easy to disperse, the expansion joint is disordered, and the placing space is occupied, and comprises a mounting ring, a first corrugated telescopic pipe is fixedly mounted at the top of the mounting ring, a second corrugated telescopic pipe is fixedly mounted at the bottom of the mounting ring, a first flange plate is fixedly mounted at the top of the first corrugated telescopic pipe, and a second flange plate is fixedly mounted at the bottom of the second corrugated telescopic pipe; a plurality of first connecting holes are annularly formed in the surface of the first flange plate at equal intervals, a plurality of second connecting holes are annularly formed in the surface of the second flange plate at equal intervals, and a shrinkage compensation assembly is arranged between the first flange plate and the second flange plate. The expansion joint can be compressed and tightened during storage and transportation, so that the expansion joint is prevented from being disordered and scattered, and the placement space is saved.
