Abstract
A single-cavity rotary joint for LNG loading and unloading comprises an outer rotary part and an inner rotary part, wherein the outer rotary part comprises an outer ring flange and an outer ring, the inner rotary part comprises an inner ring flange and an inner ring, the outer rotary part and the inner rotary part are connected by adopting a double-roller structure, and a cavity between the outer wall of the inner ring and the inner wall of the outer ring is provided with a nitrogen purging channel; the outer ring flange is provided with a nitrogen inlet, and the inner ring flange is provided with a nitrogen outlet; the upper end surface of the inner ring flange is rotationally connected with the lower end surface of the outer ring, a nitrogen sealing mechanism is arranged at the connection part, and an annular buffer gap is arranged on the lower part of the nitrogen purging channel, close to the upper end surface of the inner ring flange; an upper sealing mechanism is arranged between the upper end surface of the inner ring and the lower end surface of the outer ring flange. An outer sealing mechanism is arranged between the upper end face of the outer ring and the lower end face of the outer ring flange. And a lower sealing mechanism is arranged between the lower end surface of the inner ring and the upper end surface of the inner ring flange. The utility model discloses production and processing is more convenient, change on-the-spot dismantlement installation, nitrogen gas sweep more thoroughly, the leakproofness is more reliable.
