膨胀水箱容积计算与安装接管问题
Cubage calculation and installation piping of expansion tanks
摘要：
分析了常用计算公式存在的问题，给出了膨胀水箱容积计算公式。分析了水箱最低安装高度与系统形式和连接位置的关系、膨胀管和循环管与水箱及系统的连接位置对水循环的影响，指出对于高层建筑这两根管的连接间距和管径都可减小。指出了同时具备膨胀管和循环管的系统中定压点的位置。

Abstract：
Analyses the problems of an existed formula and provides another formula. Discusses the relations between minimum setting height and the system style, the connection position,and the influence of the connection position of expansion pipe and circulating pipe on the water circulation. Points out that the distance between these pipes and their diameter can be decreased in the case of high rise buildings. Presents the position of the constant pressure point for the system with both expansion pipe and circulating pipe.
