通过比较平衡阀单独使用和平衡阀组合压差控制器使用对水力稳定的影响,认为平衡阀组合压差控制器使用,能有效地吸收被控对象外的压力波动,使被控对象能在稳定的环境中实现线性控制。考虑安装条件的有限性,建议地铁车站采用动态流量平衡阀,同时通过比较分析,建议空调水系统设计采用末端压差控制法。%Through com paring balance valve used only w ith itused w ith pressure difference controller,itcan conclude that balance valve used w ith pressure difference controller w ill absorb the pressure fluctuation to achieve linear control. G iven lim ited installation conditions, this paper suggests using dynam ic flow balance valve and term inal pressure difference control.
