HERMETICIZING THERMAL INSULATING WALL OF THE TANK FOR STORAGE OF THE FLUID MEDIUM Russian patent published in 2017 - IPC B63B25/16 F17C3/02 B65D90/06 

FIELD: machine engineering.

SUBSTANCE: sealing and heat-insulating wall of a fluid reservoir is proposed, comprising: a heat insulating panel (1) having an inner side and sides, and a sealing plate (7), the inner side of which is designed to contact the fluid contained in the tank, and its outer side is rigidly attached to the inner side of said panel (1) at the locations of the attachment zones (14), the sealing plate (7) being provided with at least one rib (8; 9) falling from its inner side and elongated in the direction d₁ (X; y). The inner side of the heat-insulating panel (1) is provided with a slit (15; 16) for loosening the stresses located between two adjacent attachment zones (14) located on each side of said rib (8; 9), and mentioned slot has a longitudinal axis oriented in the direction d₁ (X, y) to allow the deformation of the rib in a direction transverse to the direction d₁ (X, y). The length of the slit (15; 16) for stress relaxation is less than the size of the heat-insulating panel (1) along the axis of this slot.

EFFECT: improving the performance of a cryogenic storage tank.
