AI Technical Summary
Technical Problem
The existing reactor pressure vessel tube sockets are difficult to install in confined spaces, making the installation of the top cover time-consuming and labor-intensive.
Method used
Design an adjustable-length reactor pressure vessel pipe seat. By using an expansion tube in conjunction with a locking bolt and a limiting ring, the limiting ring is allowed to slide inside the expansion tube. The connecting pipe is fixed by a locking mechanism and a guide assembly to ensure stability and sealing.
Benefits of technology
It enables convenient installation of the top cover in confined spaces, improving installation efficiency, and enhances the stability and sealing of the tube seat through the design of the locking mechanism and guide components.

Abstract
The utility model discloses a length-adjustable reactor pressure vessel tube socket, which belongs to the technical field of reactor pressure vessels, and is technically characterized by comprising a top cover, a fixed tube welded above the top cover, an expanded tube welded at the top of the fixed tube, a connecting tube connected in the expanded tube in a sliding manner, and a flange welded at the top of the connecting tube, a limiting ring is welded to the bottom of the connecting pipe, the limiting ring is connected in the expanding pipe in a sliding mode, a locking mechanism for fixing the connecting pipe is arranged on the top of the expanding pipe, and a guide assembly for limiting the angle of the limiting ring is arranged between the limiting ring and the fixing pipe. And the limiting ring slides in the expanding pipe, so that the total length of the fixing pipe and the connecting pipe is reduced, the top cover can be mounted in a narrow space, and the mounting convenience of the top cover is improved.
