The hydraulic ship lift controls the running characteristics of the ship lift by controlling the water flow.The flow control valve is an important control device for the hydraulic ship lift.Based on the hydraulic characteristics of Jinghong hydraulic ship lift,the anti-cavitation performance and the flow capacity of butterfly valve,ball valve and piston valve are compared in this paper,and the piston valve is selected as the flow control valve.According to the high docking accuracy and fast running speed of the hydraulic ship lift,this paper compares the various combinations of flow control valves,and creatively proposes the main valve and auxiliary valve co-control scheme.The co-control scheme is that a E-type piston valve as the main valve,two SZ-type piston valves as the auxiliary valves,the auxiliary valves control docking with small flow,and the main valve controls running with large flow.Jinghong hydraulic ship lift has been successfully put into operation,and the flow control valves running well.
