摘要
在建筑给排水设计中,室内排水管道的防臭方式是采用"水封"封堵的形式,一般情况下"水封"能阻挡排水立管内上升的有害气体沿每层排水横支管的分支排水管道串入室内,防止产生异味危害身体健康。在现实生活中,尤其是住宅卫生间排水管道串味的现象比较普遍,臭味时有时无、时大时小,一直困扰着人们。排水管道的防臭部位形不成水封或水封容易失效是造成室内串味的主要原因。针对臭味形成原因优化管道结构,改变密封形式,在室内排水横支管末端安装防臭阀可以从根源上解决排水管道串味的现象。
In the design for building water supply and drainage,water seal is applied to deodorize indoor drainage pipeline.Under general conditions,water seal can prevent harmful gas exhausted from drainage standpipe throughout its branches invading into inside buildings,which inhibits tainting by odor from endangering physical health.In real life,tainting by odor especially exists widely in drainage pipeline of housing washrooms.The odor comes and goes casually and varies from strong to weak,which has been plaguing users all along.The deodorization part of drainage pipeline fails to form water seal or the water seal is liable to lose efficacy,which is the major cause for indoor tainting by odor.For this reason,it is capable of radically preventing tainting by odor of drainage pipeline by optimizing pipeline structure,changing seal form and installing deodorization valve at the end of drain horizontal branches.
