船闸输水廊道门楣研究

Research of the lintel in the veranda of the navigation lock

门楣通气措施不仅可以消除阀门顶缝空化,而且可以抑制阀门底缘空化。通过对门楣缝隙比和掺气坎长度的研究,得到其临界条件和通气量大小,从而确定较优的缝隙比和掺气坎长度。

Aeratlon measur in the lintel not only avoids gaps cav itatiorl in the gates,but also abates hemline cavition in the gates. Research of gaps and aerifing banks can get critical condition and aerifing capacity so that we can confirm better gaps and aerifing hanks.
