Abstract
The utility model discloses a noise reduction through-wall pipe for building water supply and drainage, which belongs to the technical field of building water supply and drainage, and comprises a pipe body, a noise reduction shell and a fixing component, the pipe body penetrates through the noise reduction shell, the pipe body and the noise reduction shell are fixedly mounted through the fixing component, the noise reduction shell is filled with first sound insulation cotton, and the first sound insulation cotton is filled with second sound insulation cotton. The fixing assembly comprises a base fixedly connected to the side face of the noise reduction shell and a gland detachably installed on the top of the base, connecting grooves are formed in the two ends of the base, connecting blocks matched with the connecting grooves are arranged at the two ends of the gland, and locking grooves are formed in one sides of the connecting blocks. A two-way screw rod is rotationally installed in the cavity, two symmetrical sliding blocks are connected to the two-way screw rod in a threaded mode, and one side of each sliding block is fixedly connected with a locking rod matched with the corresponding locking groove. And through the arrangement of the noise reduction shell and the fixing assembly, transmission of noise in the through-wall pipe can be weakened, and the influence on the life of residents is avoided.
