  1. 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

    模擬表明,過流面積在滿足大於管道截面積40 %的條件下應盡可能小;在管道長一定並滿足流量要求的條件下,主前應採取長而細的管道,后則應採用短而粗的管道;上下游微小的壓力波動都會嚴增大開關引起的水擊,並使壓力、流量的建立需要更長的時間。
