一、概述在锅炉房内安装开式补给水箱,通过装有逆止阀的补水管向系统自动补水的方法,早在五十年代我国东北地区就有了采用。当时都是用于低温热水采暖系统。这是因为低温热水采暖系统回水干管的运行压力不高,补给水箱安装高度只需几米就有可能实现自动补水。但实践证明,当建筑物很高或循环

I. Overview The method of installing an open supply water tank in a boiler room and automatically replenishing water to the system through a make-up pipe equipped with a check valve was adopted as early as the 1950s in the northeast China. At that time, they were all used for low temperature hot water heating systems. This is because the low pressure hot water heating system does not have a high operating pressure for the main water return pipe, and the water supply tank can be automatically replenished with only a few meters of installation height. But practice has proved that when buildings are high or circulating
