Zusammenfassung:	The utility model relates to a hydraulic oil pressure control and oil recycling device which comprises a hydraulic oil outlet pipeline. A hydraulic oil pump and a pressure control safety valve are mounted on the hydraulic oil outlet pipeline, an oil return pipeline is connected on the pressure control safety valve, a hydraulic oil storage tank is connected at the end of the oil return pipeline, the hydraulic oil outlet pipeline is divided into two branches, the hydraulic oil pump and the pressure control safety valve are mounted on the two branches respectively, and the maximum bearing pressure of the pressure control safety valve is 7MPa. The set pressure of the pressure control safety valve is 7MPa, oil can return to the hydraulic oil storage tank through the oil return pipeline from a pressure control valve outlet once a pressure value is higher than a set value, so that the oil pressure is not too high, stability of the outlet pressure and fine flowability of the oil are ensured, and waste of the hydrauli
