Abstract

The invention discloses an expansion joint with a flow guiding device. The expansion joint comprises flanges, a first bellows, a second corrugated pipe, a middle pipe, an end pipe, a connecting rod, a flow guiding pipe and a check valve, wherein the first corrugated pipe is connected with the second corrugated pipe through the middle pipe; one end not connected with the middle pipe of the first corrugated pipe and one end not connected with the middle pipe of the second corrugated pipe are respectively connected with the end pipe through the corresponding flanges; the connecting rod is arranged between the flanges; the flow guiding pipe is arranged on the middle pipe and communicates with the end pipe; the check valve is arranged in the flow guiding pipe. According to the expansion joint, the problem that the expansion joint is damaged when the subsidiary stress in a conventional expansion joint pipeline is beyond the elastic range of a compensating element, so that the service life of the expansion joint is greatly shortened is solved.

Description

technical field [0001] The invention relates to the field of expansion joints, in particular to an expansion joint with a flow guiding device. Background technique [0002] The expansion joint is a kind of flexible structure arranged on the container shell or pipeline in order to compensate the additional stress caused by temperature difference and mechanical vibration. As an elastic compensating element that can expand freely, it has the advantages of reliable operation, good performance, and compact structure, and has been widely used in chemical industry, metallurgy, nuclear energy and other departments. The elastic compensation elements of traditional expansion joints have a certain elastic range. When the additional stress in the pipeline exceeds the elastic range of the compensation elements, it will cause damage to the expansion joints and greatly reduce the service life of the expansion joints. Contents of the invention [0003] The technical problem to be solved ...
