JINR staff congratulates the authors on receiving the patent for their invention!
More details about the invention
invention relates to a cryogenic technique, namely to a cryogenic flange detachable connection for a cold neutron moderator, and isintended for transporting substances in any aggregate states at cryogenic temperatures through a transport pipeline into the working chamber of a cold neutron moderator of a nuclear research reactor. Connection is a coaxial cryogenic pipeline. Shell pipeline has a telescopic sliding section with stationary casing parts. Seal at its smaller diameter is provided with a centering ring with a plastic gasket, and on the greaterside – with a pressure flange rotatable about the axis of the pipeline and an annular sealing element with a shape memory, for example a circular rubber gasket. Sliding section of the shell pipeline has the possibility of free running along the axis of the cryogenic pipeline and is connected to a section of a stationary pipeline of smaller diameter by two standard flanges. End of the sliding section on the other hand is free and enters a stationary casing of a larger diameter with a small gap. Detachable part of the inner pipeline consists of two sections of a stationary pipeline of the same diameter. They are butt-jointed using a deformable gasket and fixed by flanges, at least one of which has the ability to rotate around its axis.
EFFECT:technical result consistsin the elimination of freezing, adherence and physical and chemical changes in the transported substance.
