Beschreibung
Zusammenfassung:	The invention discloses an electrically-controlled hydraulic reversing valve and a using method, and belongs to the field of reversing valves. The electrically-controlled hydraulic reversing valve comprises a one-way valve, an overflow valve, a two-position four-way electrically-controlled reversing valve, a shuttle valve, a two-position two-way reversing throttle valve and a hydraulic pipeline; the one-way valve is connected with the shuttle valve, the two-position four-way electric control reversing valve and the overflow valve through a hydraulic pipeline; the overflow valve is connected with the two-position four-way electric control reversing valve; the two-position two-way reversing throttle valve is connected with the shuttle valve; the reversing valve is connected with the hydraulic cylinder through a hydraulic pipeline; the system flow can be accurately controlled, so that the accuracy of the push-out stroke of the hydraulic cylinder is realized; the reversing valve adopts an integrated design, the s
