The simulation shows that the valve throttle area should be little as possible but must be more than 40 % of pipe section area ; when the total length of pipe is same , and the flow quantity is enough , pipe before primary valve should be thin and long , and the pipe after primary valve should be thick and short , the upriver and downriver small pressure fluctuation will badly lead to waterdrammer pressure rising , and spending more time in establishing pressure and flow quantity 仿真表明,阀门过流面积在满足大于管道截面积40 %的条件下应尽可能小;在管道总长一定并满足流量要求的条件下,主阀前应采取长而细的管道,阀后则应采用短而粗的管道;上下游微小的压力波动都会严重增大开关阀门引起的水击,并使压力、流量的建立需要更长的时间。
For example , when the design flow of upward of the peace bridge of upward of the east - one main canal is 45m3 / s , the actual flow quantity is 23 . 8m3 / s on the 30th of september in 1989 , the water level of the transition region terminal of the mouth of hao wan flume of the east - one main canal had gained the design level of 4 . 3m , and the level between downstream and shang tian yuan tunnel was generally higher . it says that the actual discharge capacity now is only about 24m3 / s which is half of the design value . this not only make the benefit of the irrigation district abnormal , but also greatly hinder the economic development of the irrigation district , and lead to the canal run frequently at small flow , high water level , lengthen the discharge duration 如东一干渠上段太平桥以上设计流量45m ~ 3 s , 1989年9月30日实测通水流量23 . 8m ~ 3 s时,东一干渠郝湾渡槽出口渐变段末端水位已达到设计水位4 . 3m ,其下游至上天院隧洞水位也普遍偏高,即东一干渠上段目前仅能通过流量24m ~ 3 s左右,只有设计值的50左右,不仅使灌区效益得不到正常发挥,严重阻碍了灌区范围内的经济发展,而且使渠道经常处于小流量、高水位运行,延长了次通水时间,大大增加了渠道工程的安全管理难度。
