摘要
本文简要介绍200H先导式减压阀的工作原理,重点介绍用其作为由一级管网回水向二级管网补水定压主要阀件时与热网的连接方式、选型计算及与用补给水泵向二级管网补水定压方式的经济比较等问题。
This paper briefly states the operational principle of 200H forerunner pressure reducing valve, introduces the connection mode, type selection calculation and economy comparison when using it to use backwater of first - level pipeline network to supply water and stable pressure of second - level pipeline network.
