The utility model discloses a pressure-bearing fluid pipeline sealing rotary joint which comprises a rotary sleeve and an outer sleeve, the rotary sleeve is sleeved with a pressing sleeve and a positioning sleeve, a plurality of groups of sealing rings are arranged between the pressing sleeve and the positioning sleeve, the tail end of the rotary sleeve is further sleeved with a pressing plate, and the outer sleeve is sleeved with the pressing plate. The rotating sleeve is inserted into an inner cavity of the outer sleeve, and the outer sleeve is fixedly connected with the pressing plate. The structure design is reasonable, the joint rotates at any angle, and the polytetrafluoroethylene wear-resistant sealing ring is matched, so that the sealing performance is better, and water leakage and gas leakage can be directly pressed by the pressing plate without replacing a sealing element. Installation and replacement are convenient, the displacement is large, and the use requirement is met. And compared with a trad
