摘　　要：对于高度较低的超高层建筑来说,减压阀分区供水方式简单而经济,是实际工程中使用较为广泛的分区方式之一。以某超高层建筑消火栓给水系统减压阀供水方式为研究对象,通过水力计算,重点对消火栓泵的扬程、减压阀的参数及供水区域的静水压力进行校核与分析,并提出设计建议：当超高层建筑消火栓给水系统采用减压阀分区供水方式划分3个供水区域时,其极限高度可达150~170 m。For a comparatively low super high- rise building,a pressure reducer partition water supply system,one of the most widely used water supply modes in the practical projects,is simple and economic. In this paper,fire hydrant water supply system using pressure reducing valve in a super high- rise building was chosen as the research object. Through a hydraulic calculation,the lift of fire hydrant pump,parameters of pressure reducing valve and the static pressure of a water supply area are analyzed,and suggestion for the recommended fire protection water supply system in the design was put forward. When the fire hydrant water supply system of a super high- rise building using water pressure reducing valve are divided into three water supply areas,the limit height is 150 ~ 170 m.
