[0002] In the building water supply and drainage system, the noise problem caused by pipe water flow impact and vibration has long existed, affecting the comfort of the living room environment. The current widely used noise reduction methods mainly focus on wrapping sound-absorbing materials outside the pipe or adding damping lining inside the pipe structure. These technical routes have obvious limitations: the additional external sound insulation layer is complex to construct, occupies space and may cause performance degradation due to aging and damage; the internal damping lining may increase water flow resistance, reduce effective path, and also has the risk of wear and tear over a long period of use. The existing scheme cannot balance the persistent and efficient noise reduction performance, the convenience of construction and the minimum impact on the flow resistance of the pipe system.

[0028] In this embodiment, during use, by unscrewing the sealing cap 202, the exhaust pipe 201 is connected to an external air extraction device to achieve vacuuming between the inner pipe 102 and the outer pipe 101. The one-way valve 204 prevents air from re-entering the outer pipe 101. Then, by tightening the sealing cap 202, the conical ring 203 is inserted into the conical groove to further seal the exhaust pipe 201, thereby ensuring the sealing state between the inner pipe 102 and the outer pipe 101. Thus, when the inner pipe 102 vibrates, the vacuum state can prevent the transmission of noise, and the support ring 104 and the sealing ring 105 can buffer the vibration, achieving the effect of sound insulation and noise reduction. By connecting the two pipe bodies 1 end to end, and fitting the front connecting seat 301 and the rear connecting seat 302 onto the outside of the outer pipe body 101 and the fixing ring 103, and inserting the connecting plate 303 into the connecting groove 30102, then pulling the pull rod 308 causes the sliding plate 307 to slide in the connecting frame 304 and compress the compression spring 306.

By vacuumizing and reliably sealing the interlayer space between the inner and outer pipe bodies 101, the sound propagation path in the structure is effectively cut off, the vacuum state significantly blocks the outward transmission of noise generated by the water flow and pipe vibration in the pipe, and the overall sound insulation performance is greatly improved. This core measure is supplemented by the design of the support ring 104 and the elastic sealing ring 105, which provides vibration buffering at the key connection point, absorbs and dissipates energy, further weakens the source of noise generation and conduction, and comprehensively realizes excellent environmental noise control.
