摘　　要：叠压供水设备是直接从市政供水干管上取水,保证供水管网水压不小于限定压力值,且水质不被污染的给水加压设备。在总结以往经验的基础上,为了更好地规范叠压供水设备选用与安装,2010年起修编《叠压供水设备选用与安装》图集。以现行有效的规范、规程、标准为依据,选择符合国家标准的产品,标准图为施工图的补充图,以满足施工条件为重点。阐述了编制叠压供水设备的选用方法及注意事项、几种典型叠压供水设备的系统组成及工作原理图、安装图、性能参数及其选型表。介绍了叠压供水设备选用与安装标准图的编制依据、编制原则、编制内容,编制过程中遇到的各种问题及处理和解决问题的认识和体会。The pressure-superposed water supply device is used to directly take water from municipal pipe and also must keep the network pressure no less than the minimum pressure limit and secure the water from contaminations.In order to normalize the selection and installation of the pressure-superposed water supply devices,based on the previous experiences,the standard drawing for Selection and installation of pressure-superposed water supply devices has been modified since 2010.Based on current standards,procedure rules and codes,the devices meeting the national standards were selected.The standard drawings were the supplements for the construction drawings,and the key point was to meet the construction conditions.The pressure-superposed water supply devices selection methods and matters need attention,the system composition,working principles figures,installation figures,performance parameters,and selection tables of several typical pressure-superposed water supply devices were edited.This paper introduced the editing reasons,principles and content of the pressure-superposed water supply devices selection and installation standard figures,the problems in the editing process and the experiences of solving these problems.
