<p>For sealing off a pressure vessel (7), use is made of a cast closure element (3) which can be inserted into the container aperture. In order to guarantee little deformation under loading and security against malfunctions despite low production costs, the closure element (3) has, on its outer circumference (1), encircling groove-like recesses into which are inserted elements (4) which are used for the prestressing of the closure element (3). The closure element (3) is furthermore clamped against the pressure vessel (7) via retention devices (6) by means of a clamping spider (5), with the interposition of a sealing flange (8). <IMAGE></p> |
