An adjustable length reactor pressure vessel socket

Abstract

This utility model discloses an adjustable-length reactor pressure vessel pipe seat, belonging to the field of reactor pressure vessel technology. Its key features include a top cover, a fixed pipe welded to the top of the top cover, an expanded pipe welded to the top of the fixed pipe, a connecting pipe slidably connected inside the expanded pipe, a flange welded to the top of the connecting pipe, a limiting ring welded to the bottom of the connecting pipe, and the limiting ring slidably connected inside the expanded pipe. A locking mechanism for fixing the connecting pipe is provided at the top of the expanded pipe, and a guide component for limiting the angle of the limiting ring is provided between the limiting ring and the fixed pipe. This utility model, through the combined use of the expanded pipe, locking bolt, and limiting ring, allows the limiting ring to slide inside the expanded pipe, thereby reducing the total length of the fixed pipe and connecting pipe, enabling the top cover to be installed in confined spaces and improving the ease of installation.
