An expansion joint protection tube

Abstract

An expanding joint protecting pipe comprises joints, a corrugated pipe, protecting pipes and a protecting pipe key; the number of the joints is two, and the inner diameter of the joint on the left side is smaller than the inner diameter of the joint on the right side; the corrugated pipe is fixedly connected between the two joints; the number of the protecting pipes is two, and the two protectingpipes are correspondingly inserted into the corresponding joints; the two joints are each internally provided with uniformly arranged first grooves; the diameters of the first grooves are sequentiallydecreased in the direction from the joints to the corrugated pipe; clamping shafts are fixedly connected in the grooves through springs; the ends, close to the protecting pipes, of the clamping shafts are in spherical face design, and the clamping shafts are closely attached to the inner walls of the first grooves to be designed; the surfaces of the two protecting pipes are each provided with uniformly arranged second grooves; and the second grooves correspond to the first grooves one to one, and the opening diameters of the second grooves are equal to the diameters of the corresponding firstgrooves. The expanding joint protecting pipe is mainly used for solving the problems that when an existing expanding joint is damaged, finding is not in time, damage is easily caused, replacing is not in time and replacing is troublesome.

Description

technical field [0001] The invention belongs to the field of application technology of expansion joints, in particular to an expansion joint protection tube. 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 and vibration reduction. In heating, i...
