摘要
根据阀门逐渐关闭时产生三角形水击起始波的假定，推导出直接水击压强的计算公式；从而得到当压力管道发生直接水击时，存在一个水击压强的最大值，并给出其解；还得出水击波速与阀门关闭方式无关．
In this Paper, an equation for computation of the direct waterhammer pressure is develops based on the assumption, that a trianglar initial waterhammer wave is formed during the gradual closing of a valve.It is also shown in this paper that the maximum waterhammer pressure has a maximum valve when direct Waterhammer happens in penstocks, and that the velocity Of waterhammer waves is independent of the closing. method of the valve.at
