The invention discloses a low-temperature rotating connector structure which comprises a shell, a rotating shaft and a flange. The shell is arranged on the outer side of the rotating shaft in a sleeving manner. The flange and the rotating shaft are arranged coaxially. The flange is installed on the shell, and thus the flange and the rotating shaft abut against each other in the axis direction. A ring-shaped wall is arranged on the abutting-against end face of one side, close to the rotating shaft, of the flange in a protruding manner. The ring-shaped wall is arranged on the outer side of the rotating shaft in a sleeving manner. The abutting-against end face located in an internal space of the ring-shaped wall forms a first abutting-against ring face. The outer side wall of one side, closeto the flange, of the rotating shaft is of a reducing structure, and thus the outer side wall of the rotating shaft forms a second abutting-against ring face. The first abutting-against ring face andthe second abutting-against ring face are arranged oppositely. A first sealing assembly is arranged between the first abutting-against ring face and the second abutting-against ring face in an abutting-against manner. The first sealing assembly comprises a first sealing ring stop ring, a sealing ring and a second sealing ring stop ring which are sequentially arranged in the axis direction. The low-temperature rotating connector structure is simple, liquid is leaked less, and the sealing performance is excellent.
Description
technical field [0001] The invention relates to the technical field of cryogenic engineering, in particular to a cryogenic rotary joint structure. Background technique [0002] The cryogenic rotary joint is a closed rotary connector that rotates 360 degrees to transport cryogenic media. In the LNG loading skid, the low-temperature rotary joint is mainly used on the loading and unloading arm, so that the loading and unloading arm can be telescopically moved, better docked with the tank car, and greatly facilitates the free connection between the tank car filling port and the front section of the loading arm . The quality of the cryogenic rotary joint directly determines the value and service life of the entire loading arm. At present, the domestic low-temperature rotary joint still has the following problems: the liquid seal of the commonly used low-temperature rotary joint is a double-face seal, there will be two liquid leaks, and the structure is relatively complicated. ...
