On cavitation and cavitation erosion test stand, slit cavitation flow tests in a 1:1 slice model of the top seal of eccentric-hinge radial gate installed at the flushing tunnel of Xiaolangdi hydro-junction on Huanghe River were carried out. 在空化空蚀试验台上,对黄河小浪底水利枢纽排沙洞偏心铰弧形闸门顶水封的1:1切片,进行缝隙空穴流试验。
Finally, through the study of structural forms of standard gate slot and narrow slit gate slot, the appropriate gate bottom rim patterns are recommended for each type gate slot, respectively. 通过对标准门槽及窄缝门槽的体型研究,分别拟定了适合各自门槽的闸门底缘型式。
