Composite pipeline

Abstract

The invention discloses a composite pipeline which comprises a pipe body. A cavity is formed in the inner side end of the pipe body, a supporting box is arranged at the top of the cavity, and an arc-shaped concave face is arranged on the lower end face of the supporting box. A middle pipe is arranged at the bottom of the supporting box, and a water drainage channel is arranged in the middle of themiddle pipe. The top of the middle pipe makes contact and is engaged with the arc-shaped concave face of the supporting box at the upper end, and an elastic supporting piece is arranged at the bottomof the middle tube. The middle tube is pressed towards the bottom face of the supporting box through the elastic supporting piece at the bottom, the two sides of the elastic supporting piece are buckled into clamping grooves in the inner wall of the pipe body correspondingly, and waterproof glue is injected into the clamping grooves for bonding and fixing. According to the composite pipeline, themiddle pipe is adopted to achieve normal water drainage, when the water drainage amount in the middle pipe is large, the elastic supporting piece is made to descend by increasing weight, so that thewater in the middle tube is made to leak out; and a suspended transitional cavity is used for achieving silent water drainage, and the water drainage amount is guaranteed while the requirement for silence is met.

Description

technical field [0001] The invention relates to the field of pipelines, in particular to a composite pipeline. Background technique [0002] Existing drainage pipes arranged horizontally indoors, in rainy days, due to the large amount of rainwater, the noise inside the pipes increases. In this way, if the indoor environment is extremely quiet, the room will be very noisy due to the drainage of the pipes. Therefore, for this type of pipes, which we had to reset to meet the requirements for silent drainage; [0003] Some of the current silent pipelines generally have a sound insulation layer inside the pipeline so that the internal sound will not be transmitted to the outside. However, when the displacement is large, the entire pipeline will vibrate, and the outside of the pipeline and the wall will vibrate. , the pipeline will still produce noise due to vibration. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide ...
