SEALED HEAT-INSULATED TANK Russian patent published in 2021 - IPC F17C3/02 F17C13/00 

FIELD: gas industry.

SUBSTANCE: invention relates to the storage of gases. A sealed, heat-insulated tank contains a set of tank walls that delimit the internal space of the tank. The pressure element (39, 65) is attached directly or indirectly to the protruding element and passes transversely to the protruding element in order to carry the load in the direction against the insulating blocks (8) between which the protruding element is located. The thickening gasket (63) is located around the protruding element (62) of the mounting and positioning part (10). The thickening gasket (63) has an inner surface on which the insulating blocks (8), between which the protruding element is located, are held in the pressed state by the pressure element. The mounting and positioning part includes a positioning insert that interacts with the protruding element and is located on the thickening gasket, so that the gasket (63) is located between the supporting structure and the positioning insert (64) in the direction of the tank wall thickness. The positioning insert is located between the pressure element and the gasket for thickening in the direction of the tank wall thickness, the positioning insert contains a thrust surface facing up in the direction of the support wall. The outer side surface (1) rests against the thrust surface of the positioning insert, so that the positioning insert supports the side surface of the insulating block at a predetermined distance from the protruding element (62).

EFFECT: reducing point stresses.
