Abstract
The utility model discloses a silencing pipe. The silencing pipe comprises a pipe body (1), wherein a helical rib (22) is arranged on the inner surface of the pipe body (1). Because the helical rib (22) is arranged on the inner surface of the pipe body (1), the helical rib is utilized to guide water flow, so that the water in the pipeline can flow downwards in a rotating manner, and because the water flows along the inner wall of the pipe during flowing, the water which makes an included angle with the axial direction of the pipe cannot impact the inner wall of the pipe again and again when flowing into the pipe, so that the effect of reducing noise is achieved. Meanwhile, when the water flows along the wall in a rotating manner, an expedite air swirl column can be formed in the pipe line, so that the pressure in the pipeline cannot severely fluctuate, and therefore various noises and air bubble sound which are produced when the water which is impacted to scatter is in contact with the air can be greatly reduced; meanwhile, the arrangement of the helical rib (22) enhances the compressive strength of the pipe body (1) and increases water discharge.
