Flow-adjusting, air-entraining, pressure-reducing and flow-stabilizing system of hydraulic ship lift

The invention discloses a flow regulating, aerating, pressure reducing and flow stabilizing system of a hydraulic ship lift. The flow regulating, aerating, pressure reducing and flow stabilizing system comprises a flow control device, an active aerating device, a collision energy dissipation device and a pressure stabilizing sudden expansion body. The flow control device is arranged on the water conveying channel and controls the opening degree of the water conveying channel. A pressure stabilizing sudden expansion body is arranged on the downstream side of the flow control device; the flow control device is communicated with the pressure stabilizing sudden expansion body through the air supply cavity; the active aeration device is communicated with the air supply cavity; the collision energy dissipation device is contained in the pressure stabilizing sudden expansion body and communicates with the air supply cavity. The collision energy dissipation device is arranged on the downstream of the water conveying
