Beschreibung
Zusammenfassung:	The invention provides a water flow control device and method in an aluminum casting system, and belongs to the technical field of casting. The control device comprises a water flow meter, at least one pressure sensor, an electric drive proportional valve, a proportional control water pump, a drainage valve and a control module, the water flow meter is used for detecting the flow value of cooling water in a waterway and feeding back the flow value to the control module, and the pressure sensor is used for detecting the pressure value of the cooling water in the waterway and feeding back the pressure value to the control module. The electric-driven proportional valve is used for receiving an instruction of the control module to control the proportional control water pump, the proportional control water pump pumps cooling water from the main water source into the water path according to the control of the electric-driven proportional valve, and the drainage valve is connected with the control module to discharg
