Problems solved by technology

The disadvantage of the traditional expansion joint is that when the axial deformation of the bellows exceeds its elastic deformation range due to the temperature rise of the expansion joint, the bellows will lose their elastic capacity and become soft, which will shorten the service life of the expansion joint.

Abstract

The invention discloses a rubber expansion joint resisting axial deformation. The rubber expansion joint comprises first flanges, second flanges, a rubber bellows and a limiting mechanism. The two ends of the rubber bellows extend in the radial direction to form extending parts, the extending parts are provided with through holes, the rubber bellows penetrates the second flanges, the extending parts of the rubber bellows are clamped through the first flanges and the second flanges and are locked through screws penetrating the first flanges, the through holes in the extending parts and the second flanges to be matched with nuts, and the limiting mechanism is arranged between the second flanges positioned at the two ends of the rubber bellows. According to the rubber expansion joint resisting axial deformation, the problem that the bellows will lose elasticity to become loose and soft when due to pipe warming the expansion joint causes the bellows to axially deform to exceed its elastic deformation range is solved.

Description

technical field [0001] The invention relates to the field of expansion joints, in particular to a rubber expansion joint for preventing axial deformation. Background technique [0002] Expansion joints are also customarily called compensators, or expansion joints. It is composed of bellows and end pipes, brackets, flanges, conduits and other accessories that constitute the main body of its work. 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 orde...
