High attitude area dynamic water start-stop plane gate groove
The invention discloses a high attitude area dynamic water start-stop plane gate groove. The high attitude area dynamic water start-stop plane gate groove comprises a gate groove body, the ratio of the width W of the gate groove to the depth D of the gate groove is W/D=1.7-1.9, the ratio of the downstream alternate distance delta to the width W of the gate groove is delta/W=0.08-0.12, the slope ratio of downstream alternate distance delta to the length X of a slope is delta/X=1:13-15, and the distance Y between the downstream surface of the gate groove and a downstream breast wall is not smaller than 1.5 times the width W of the gate groove. Each circular bead formed in the corresponding slope alternate distance is R100-R80. Each internal circular bead of the gate groove is R100. By means of the high attitude area dynamic water start-stop plane gate groove, gate groove cavitation erosion and gate vibration brought by the gate groove cavitation erosion are reduced, and therefore the safety operation of the plane gate is guaranteed.
