Problems solved by technology

The traditional bead punching is to punch holes manually, which is laborious and inefficient
Moreover, due to the relatively large volume and heavy weight of the compensator, it is difficult to lift during transportation.

Abstract

The invention discloses a fiber expansion joint with a novel depression bar and capable of being easily hoisted. A certain number of fixing holes are mechanically punched on the depression bar, hanger plates are symmetrically mounted on a draw bar and are metal plates with certain thicknesses, and through holes are disposed on the hanger plates. The fixing holes are mechanically punched on the depression bar, labor can be greatly saved, production efficiency is improved, more fixing spaces can be selected during installation due to the oblong fixing holes, the problem that a traditional depression bar with circular fixing holes can only be fixed at a fixed point is avoided, and installation efficiency can be enhanced. In addition, the hanger plates are symmetrically mounted on the draw bar, accordingly, the fiber expansion joint is convenient in shipping when transported, and a compensator cannot be easily damaged during transportation.

Description

technical field [0001] The invention relates to an expansion joint, in particular to a fiber expansion joint. [0002] Background technique [0003] 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. As an elastic compensation 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. Fiber expansion joints can provide a large amount of multi-directional compensation at a small axial installation distance, and at the same time can effectively eliminate the cumulative installation error of the entire system, and have better application prospects than traditional metal expansion joints. The fiber expansion joint ring belt is covered outside the insulation layer, and its main function...
