[0043] like Figures 1 to 5 As shown, the utility model provides a residential water pipe noise reduction system, including a noise reduction pipeline system and an external pipe sound insulation component. The noise reduction pipeline system includes a main water pipeline 1, a branch pipe 2, a first exhaust component 3 and a second exhaust component 4. The main water pipeline 1 is connected to a plurality of branch pipes 2. One end of the first exhaust component 3 is connected to the main water pipeline 1 for discharging the gas in the main water pipeline 1. One end of the second exhaust component 4 is connected to the branch pipe 2 for discharging the gas in the branch pipe 2. The external pipe sound insulation component is wrapped around the outer wall of the pipeline of the noise reduction pipeline system. In this embodiment, the arrangement of the first exhaust component 3 and the second exhaust component 4 can effectively discharge the gas in the pipeline, thereby effectively solving the pipeline vibration caused by exhaust, avoiding the water hammer phenomenon in the pipeline and reducing the generation of noise. At the same time, the arrangement of the external pipe sound insulation component can effectively isolate the transmission of noise, thereby effectively achieving the noise reduction effect of the residential water pipe.

[0044] Preferably, in this embodiment, the first exhaust component 3 includes a first connecting section 31, which is obliquely arranged on the main water pipeline 1 and is connected to the main water pipeline 1; the first connecting section 31 is used to achieve the communication effect with the main water pipeline 1, and the gas in the main water pipeline 1 is discharged through the first connecting section 31. At the same time, the inclination direction of the first connecting section 31 is opposite to the water flow direction in the main water pipeline 1, which can avoid the water flow in the main water pipeline 1 from leaking from the first connecting section 31 to a certain extent; similarly, the second exhaust component 4 includes a second connecting section 41, which is obliquely arranged on the diversion branch 2, and the second connecting section 41 is connected to the diversion branch 2; the inclination direction of the second connecting section 41 is opposite to the water flow direction in the diversion branch 2.

Therefore, in this embodiment, a buffer section is provided at the location where the water flow impact is large, and the buffer protrusions 11 therein are used to reduce the impact force of the water flow. Specifically, in order to reduce the impact of the buffer protrusions 11 on the normal flow of water while reducing the impact of the water flow, in this embodiment, the upper end surface of the buffer protrusion 11 is an arc-shaped surface and is tangent to the inner wall of the main water supply pipe 1; the lower end surface of the buffer protrusion 11 is also an arc-shaped surface and is tangent to the inner wall of the main water supply pipe 1; the intersection of the upper end surface and the lower end surface is an arc-shaped surface structure.
