Abstract

The invention discloses a totally-sealed fiber expansion joint with a novel trim strip. The totally-sealed fiber expansion joint comprises a ring belt, a heat-preservation layer, the trim strip, an upper connecting pipe, a lower connecting pipe, an upper annular plate, a lower annular plate and a pull rod, wherein at least two fixing holes are formed in the trim strip; the two sides of the ring belt are fixed on the upper and lower annular plates in a sealing way through the fixing holes by the trim strip respectively; the heat-preservation layer is arranged between every two of the upper connecting pipe, the lower connecting pipe, the upper annular plate, the lower annular plate and the ring belt; and the fixing holes are punched in a mechanical punching way. The fixing holes are punched in the trim strip in the mechanical punching way, so that manpower is greatly saved, and production efficiency can be improved; due to the oblong fixing holes, large fixing spaces can be selected in mounting rather than fixed points of the conventional circular fixing holes, so that mounting efficiency can be improved; and the internal heat-preservation layer can be well protected by the total-sealing ring belt, and prevents the heat-preservation layer from chemical corrosion from outside and in a pipeline, so that the service life of the fiber expansion joint is prolonged.

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...
