FIELD: structural elements of vessels.
SUBSTANCE: invention relates to the design of cryogenic high-pressure vessels and methods of releasing liquefied gases therefrom. Cryogenic vessel consists of an inner vessel installed inside a hollow casing; at that, the space between the inner vessel and the casing is evacuated and filled with heat-insulating material. In the left bottom of the vessel there is a gas discharge line, a line for filling the vessel with liquid, a line for supplying liquid to a consumer and a pressure rise line, each of which is brought out through the casing into the atmosphere and is equipped with valves. Level gauge, a drain connection, a pressure boost valve, a pressure regulator, an evaporator, safety valves, a pressure gauge valve and a pressure gauge are installed in series on the pressure rise line; at that, on the pressure rise line after the evaporator there is a branch to the gas discharge line. Line for dispensing liquid to the consumer includes a U-shaped pipe installed inside the inner vessel, in the upper part of which there is a hole and a throttle element in the form of a washer with an inner conical hole is installed.
EFFECT: possibility of long-term storage of cryogenic liquids and their automatic delivery to the consumer under the specified pressure.
