The invention provides an expansion joint. The expansion joint comprises a left connecting pipe, a right connecting pipe, a bellows, a left diversion cylinder and a right diversion cylinder; the right end of the left connecting pipe and the left end of left diversion cylinder are fixed in a sealed mode, the outer diameter of the left diversion cylinder is smaller than the inner diameter of the right diversion cylinder, an externally protruding ring is arranged on the outer wall of the right end of the left diversion cylinder, an internally protruding ring is arranged on the inner wall of the left end of the right diversion cylinder, and the right end of the left diversion cylinder extends from the left end of the right diversion cylinder. According to the expansion joint, by means of the protruding structures and diversion pipes sealed through a sealing part, diversion of liquid in the expansion joint can be achieved, thermal expansion of a pipeline is met, high degree of sealing can be achieved, cleanliness of the inner wall of the bellows is guaranteed, the service life of the expansion joint is prolonged, the sealing part has the self-tight sealing function, the sealing effect can be further enhanced after thermal expansion of the pipeline is achieved, and the sealing effect is good.
Description
technical field [0001] The invention relates to the technical field of expansion joints, in particular to an expansion joint. Background technique [0002] Expansion joints are customarily also called expansion joints. It consists of a bellows (an elastic element) that constitutes its main body and accessories such as end pipes, brackets, flanges, and conduits. The expansion joint is a flexible structure arranged on the container shell or pipeline in order to compensate the additional stress caused by temperature difference and mechanical vibration. Utilize 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, or compensate the axial, lateral and angular displacement of pipelines, conduits, containers, etc. It can also be used for noise reduction, vibration reduction, and heating. In order to prevent the deformation or dam...
