Cabin-penetrating clamping sleeve joint for ship

The invention discloses a cabin-penetrating clamping sleeve joint for a ship. The cabin-penetrating clamping sleeve joint for the ship is sleeved on a pipeline, the inner diameter of the cabin-penetrating clamping sleeve joint for the ship is larger than the outer diameter of the pipeline, the cabin-penetrating clamping sleeve joint for the ship comprises a joint body, a pipeline clamping ring and a nut, the outer walls of the two ends of the joint body are correspondingly in threaded connection with the inner wall of the nut, the pipeline clamping ring is arranged between the end of the joint body and the nut, and the nut restrains the displacement freedom degree of the pipeline clamping ring in the axis direction of the pipeline. In the process that the nut and the joint body are connected and tightened through threads, the nut pushes the pipeline clamping ring to move in the direction close to the joint body in the axis direction of the pipeline, the pipeline clamping ring clamps the pipeline so that the e
