价值分析原理在真空排污系统管材选择中的应用

Application of Value Analysis Principle in SelectingPipe Materials of Vacuum Sewerage System

真空排污系统改变了传统的排水方式,以真空作为动力输送污水.合理选用真空排污系统的管材是节省工程投资、确保系统安全运行的主要环节.针对真空排污系统的特性,运用价值分析的方法,以三种管材为例,介绍了方案比较中各项功能权重的确定和评分方法,并对其进行了价值分析,选择出合适的管材,并提出了应注意的问题.

The vacuum sewerage system changes the traditional drainage system, itcan collect sewerage by the vacuum suction.It is a key link to select pipe materials reasonably for sewer engineering, this selection is very useful to savethe engineering investment and keep the operation in safety. According to the characters of vacuum sewerage system and using value analysis method, the determination of weights and the point rating for each function term are illustrated by threekinds of pipes. The questions that should be paid attention to are put forward.
