摘　　要：论述了消火栓给水系统不同工况时剩余水头的计算,并通过计算和分析,得出设高位水箱或水箱及增压设施的消火栓给水系统宜按水箱供水工况确定减压孔板的结论,及提出消火栓口压力大于300kPa时就宜开始减压观点。The calculation of residual head in different water status is discussed in water supply system of hydrant in article. By calculation and analysis ,it is believed that the orifices will be determined on the basis of water status of elevated water tank in the water supply system of hydrant if setting up elevated tank or elevated tank & pressure rise equipment. It is appropriate to start pressure relief when the hydrant cap's pressure exceeds 300kPa.
