摘　　要：以33层住宅消防给水系统为研究对象,通过对其水压强度试验时出现渗漏的原因分析,发现室内消火栓由于产品公称压力和密封性能试验压力低于系统其他组件,而成为消防给水系统试压是否成功的控制节点。对实际工程中消防给水系统的水压试验,提出了一些优化建议。This study has taken the 33 rd floor residential fire water supply system as the research object. Through the analysis of the causes of leakage in the water pressure strength test, it was found that the indoor fire hydrant became the control node of the successful pressure test of the fire water supply system because the product nominal pressure and sealing performance test pressure were lower than other components of the system. Some optimization suggestions are put forward.

关 键 词：消防给水系统 水压强度试验 室内消火栓 密封性能试验
