Pipeline joint device capable of achieving multi-degree-of-freedom active adjustment and butt joint

Abstract

The invention provides a pipeline joint device capable of achieving multi-degree-of-freedom active adjustment and butt joint. A pipeline support and a supporting adjustment device are installed on thetwo sides of the upper surface of a base; a straight pipe connecting pipe is installed on the top of the pipeline support; an outer sleeve is installed on the top of the supporting adjustment device;the end, close to the outer sleeve, of the straight pipe connecting pipe is connected with an inner pipe in a sealed and sliding manner through a radial compensator; the radial compensator is composed of a connecting pipe and corrugated pipes at the two ends; and at least two universal joint adjusters are connected between flanges at the two ends of the radial compensator. According to the pipeline joint device, the pipeline support is a fixed end support, the supporting adjustment device based on a 4-PSS parallel mechanism is a movable end support, and the outer sleeve can be driven to movein the axial direction and rotate in the circumferential direction relative to the inner pipe; and meanwhile, the outer sleeve and the inner pipe can be driven to move in the radial direction throughthe flexibility of the radial compensator, finally, axial and radial movement and circumferential rotation of the outer sleeve and the joint device are achieved, and butt joint connection of the outersleeve and joints at different external positions is facilitated.

Description

technical field [0001] The invention belongs to the field of pipeline connection joints, and in particular relates to a pipeline joint device capable of realizing multi-degree-of-freedom active adjustment and docking. Background technique [0002] Pipelines are the main carrier for transporting fluid media. In some engineering pipelines, the displacement of the end of the pipeline due to external factors, or in some test pipelines, it is necessary to replace different pipeline components. It is required for different pipeline components , can also quickly realize the end-to-end connection between pipeline components, which requires the necessary pipeline compensation joints to be set in the pipeline. [0003] The pipe compensator is a connecting piece that compensates for the displacement of the end of the pipe due to thermal expansion and contraction in the pipe connection. The existing pipeline compensators are adjusted passively, and the compensation amount is limited. ...

AI Technical Summary

Problems solved by technology

The bellows type compensator is a flexible structure and can be bent, but its axial compensation amount is relatively small compared to its own size, and the bellows type compensator with a long axial dimension can only compensate a relatively small displacement

The sleeve type compensator compensates by the relative movement of the inner tube and the outer tube, which can achieve a large amount of axial compensation, but when the pipe has a slight radial displacement, it is easy to cause the sleeve to be stuck

Existing pipeline compensators have their own application limitations, and there are many inconveniences in installation and construction.
