Method of arranging a seal between a pressure vessel, preferably a reactor vessel, and its lid by means of a torrid ring provided with flanges

摘要

There is provided a seal between a pressure vessel, in particular a vessel for a nuclear reactor, and its lid, which rests on a ledge in the vessel. A toroid ring with flanges is placed on top of the lid and a collar in the vessel. The inner flange is sealingly clamped against the lid by means of a ring with support legs of the lid, whereas the outer flange is clamped against the collar by means of displaceable clamps.
