Silenced PPR water supply pipe structure

Abstract

The invention discloses a sound-absorbing PPR water supply pipe structure in the technical field of water pipes. A sound wave buffer chamber is arranged between the wave-shaped sound-absorbing cotton, and the outer wall of the wave-shaped buffer pipe is provided with a sound-absorbing pipe, and the peripheral surface of the sound-absorbing pipe is compounded with an expansion type sound-absorbing pipe, and the wave-shaped buffer pipe provided on the outer wall of the PPR pipe passes through the wave form The sound-absorbing cotton and the sound wave buffer chamber can perform primary noise reduction on the drainage noise inside the water pipe, and further weaken the drainage noise by using the sound-absorbing wedge inside the sound-absorbing pipe, and install an expansion-type sound-absorbing pipe on the outermost layer of the pipe wall, using the expansion principle of sound waves , can carry out the final noise reduction on the drainage noise, and through the combination of layers of pipes, the drainage noise can be greatly reduced to meet the needs of users.

Description

technical field [0001] The invention relates to the technical field of water pipes, in particular to a sound-absorbing PPR water supply pipe structure. Background technique [0002] PP-R pipe is also called three-type polypropylene pipe and random copolymerized polypropylene pipe or PPR pipe. Long service life and other advantages, widely used in building water supply and drainage, urban and rural water supply and drainage, city gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. PP-R pipes are made of random copolymerized polypropylene, which is extruded into pipes and injection molded into pipe fittings. [0003] However, there are some problems in the use of existing PPR pipes. For example, when PPR pipes are used as drainage pipes, the drainage noise is higher than that of traditional cast iron pipes. In some occasions where noise needs to be kept...
