摘要
目前 ,随着PVC -U排水管的推广应用 ,排水管道噪声也严重影响了人们的日常生活 ,因此排水管道减噪已势在必行。本文在测试、比较了铸铁管、普通PVC -U管、空壁管、空壁螺旋管及普通PVC -U管与偏心三通、消音三通、多功能地漏的排水噪音的基础上 。
At present,along with the popularization and application of PVC-U drainpipe,the noise of drainpipe has affected people's daily life severally, so it has been a necessary trend to reduce the noise of drainpipe. In the basis of testing and comparison the noise of the cast iron drainpipe, PVC-U drainpipe, hollow-wall drainpipe, spiral hollow-wall drainpipe and the connection of bias tee-pipe, reducing-noise tee-pipe, multi-function floor drain to PVC-U drainpipe ,the cause of drainpipe noise was analysed and the way of solution was presented in this paper.
