The invention relates to the field of corrugated expansion joints, specifically a corrugated expansion joint, including an expansion joint body, the upper and lower ends of the expansion joint body are detachably connected with a fixed ring through a first bolt, and the inner diameter of the fixed ring is equal to that of the expansion joint body. The inner diameter of the fixed ring is the same as that of the expansion joint body. The side of the fixed ring away from the expansion joint body is fixedly connected with a fixed pipe, and the end of the fixed pipe far away from the expansion joint body is equipped with a connecting mechanism. Support plates are installed between both sides of the ring, a separation mechanism is installed on the support plates, and a protection mechanism is installed on the outside of the expansion joint body. When installing the fixing ring of the mechanism, the two pipes that need to be installed in the present invention can be connected together through the connecting pipes of the two connecting mechanisms, and then the expansion joint can be installed between the two fixing rings, and one worker can realize The installation of the present invention, and the installation process is comparatively convenient.
Description
technical field [0001] The invention relates to the field of corrugated expansion joints, in particular to a corrugated expansion joint. Background technique [0002] Expansion joints, also called compensators or expansion joints, belong to a compensating element that uses the effective expansion and contraction deformation of the bellows of its working body to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction. The expansion and contraction effect of the joint is mainly realized by the bellows. The function and strength design of the bellows expansion joint is mainly the design of the bellows. Different designs and combinations of the bellows can make the bellows stretch, compress or Bending to form three basic forms of corrugated expansion joints: axial, transverse and angular. [0003] For the installation process of the pipeline transported in the trench, it is necessary to install one end of the expansion...
