近年来,给排水工程的安装与建设受到了人们的广泛关注。在现代化建筑工程建设过程中,给排水工程是最基础的工程之一。过去,人们在给水工程中采用的是二次加压供水设备,但是根据实践经验表明,这种在实际使用过程中存在着许多问题,我们需要将无负压供水设备应用在其中。本文就无负压供水设备的组成及其优势进行分析,以供参考。 In recent years, the installation and construction of water supply and drainage projects have received widespread attention. In the process of modern building construction, water supply and drainage works are one of the most basic projects. In the past, people used secondary pressurized water supply equipment in water supply projects, but according to practical experience, there are many problems in the actual use process. We need to apply non-negative pressure water supply equipment in it. This article analyzes the composition and advantages of non-negative pressure water supply equipment for reference.
