摘　　要：以跃层住宅为研究对象,采用现场试验观察法,根据气水两相流流态,对不同用水方式和入户水压的不同分支管路停水后首次用水的排气噪音、水流喷溅与震荡进行了比较和分析。结果表明:给水管路几何参数是气团聚积与水流震荡的约束边界,是排气特征的重要影响因素;合理的管路布置、恰当的用水方式和较低的入户水压能降低停水后首次用水的水流震荡和排气噪音。Field tests and observation were adopted for case study of skip-floor apartments. Based on the air-water two phases flow, the degrees of noise, flow sputter and surge during the first use after suspension of water supply in different branch pipings under the different water use manners and hydraulic pressures were compared and analyzed. The results show that piping geometrical parameters are boundaries of air collection and flow surge, and are also important factors which affect the air-exhausting characteristics. It can reduce flow surge and noise during the first use after suspension of water supply by rationalizing piping layout, fitting water use manners and lowering hydraulic pressure.
