8、e.提示：强调斗前水深稳定可控，因为我们的竞争对手都做不到。当达到工作暴雨强度时，我们的斗前水深是稳定不变的，说明流量相当稳定。而竞争对手的斗前水深是不稳定的，说明流量也不稳定，对系统的伤害是很大的。另外当暴雨强度超出工作范围时，我们的斗前水深会一下子上深，说明系统已饱和，不再能排更多的水。只能通过溢流口排水。但竞争对手的系统却还能排更多的水，说明管道中的流速在不断地增加，这样会使管道超出它的疲劳极限，从而大大降低系统的寿命。2003.8.20/by kiki Slide 7Geberit pluvia虹吸形成的过程虹吸形成的过程(The progress of syphonic format

9、ion)刚开始下雨，系统仍处于重力流状态，水平管内水流速度较慢，水位逐渐上升。In the beginning of rain,the system is in gravity states,the velocity in horizontal pipe is very slow,water level is increasing gradually.2003.8.20/by kiki Slide 8Geberit pluvia虹吸形成的过程虹吸形成的过程 The progress of syphonic formation随着屋面水位的不断上升，当达到计算斗前水深要求时，系统产生虹吸，排水量

10、增大。当斗前水位回落至标准以下，系统又将回复到重力状态。因此在降雨初期，虹吸流与重力流总是交替产生。Along with the increase of water level,the system will create syphonic effect when the calculated water depth is reached,and drainage capacity will increase.While the system will go back to gravity states when the water level drop down below the calc
