Tank support structure e.g. for super vacuum isolation tank for low temperature liquid gas, has radial support between outer hull and interior container with small cap fitted over ball fitting

摘要

The tank has a radial support, between an outer hull (110) and an interior container (120). A small cap is fitted over a ball fitting by lowering in the center of the cap the interior container and the radial support is at the curved surface of the small cap. The radial support has a support plate and two attachment rings on both sides of the radial support plate. The attachment rings at the exterior of the radial support plate is fastened to the cap. A self-adapting gap is formed between the radial support plate and the cap. The diameter of the cap in the lowering direction becomes smaller. The radial support plate and the attachment ring with are pressed against the inside of the cap.
