摘要
排水立管内的压力波动是衡量排水系统性能的重要指标之一,只有压力波动不超过一定值时,才能保证卫生洁具内的水封不被破坏.现对压力传感器和U形管这两种测量方法进行了对比试验,结果表明,U形管的内径和粗糙度越接近卫生洁具存水弯,越能反映立管内压力变化对实际水封的影响.
The fluctuation of pressure in vertical stack is an important index of the drainage system. The water seal wouldn' t be destroyed unless the pressure fluctuation in pipe gone beyond the limit. The difference between the press transducers and the manometer was distinguished by experiment. Experiment and date analysis verified that change of the water seal was more practically reflected by the manometer.
