Abstract

The invention discloses a spherical universal telescopic device. The spherical universal telescopic device comprises a first spherical base, a second spherical base, a short pipe ball and a long pipe ball, wherein the first spherical base and the second spherical base are symmetric; a first ball body is arranged at one end of the short pipe ball and fixed to the interior of the first spherical base through a pressing plate assembly; the ball center of the first ball body can be adjusted in the first spherical base; the short pipe ball can swing around the ball center; an inner movable pipe sleeve is arranged at the other end of the short pipe ball; a second ball body is arranged at one end of the long pipe ball and fixed to the interior of the second spherical base through a pressing plate assembly; the ball center of the second ball body can be adjusted in the second spherical base; the long pipe ball can swing around the ball center; an outer fixed pipe sleeve is arranged at the other end of the long pipe ball; the outer fixed pipe sleeve is matched and connected with the inner movable pipe sleeve. The spherical universal telescopic device is simple in structure, high in leakproofness and capable of meeting the requirements for absorbing the phenomena such as large deformation, displacement, deflection and stress concentration.

Description

technical field [0001] The invention relates to the field of pipeline installation, in particular to a spherical universal expander. Background technique [0002] During the production process, the transportation of fluid materials is carried out through the pipe network. There must be a starting point for the installation of the pipeline for each monomer fluid material, and there must be corners in the entire pipeline. Fluid transport must be carried out in pipelines. For the entry and exit of materials in large fixed containers, inlet and outlet joints are installed as the starting point for the installation of outlet pipes. The installation direction of the pipeline can be drawn out in the horizontal direction or in the vertical direction. [0003] The installation of the pipe must have a certain precision. However, in the process of use, due to the temperature difference between the use and the installation, the pipeline has a certain amount of elongation; and due to...
