Abstract

The invention discloses an intelligent control hydraulic system, and relates to the technical field of hydraulic control. The intelligent control hydraulic system comprises a valve block capable of being connected with a controller. The valve block comprises a hydraulic control one-way valve, a proportional overflow valve, a proportional direction valve, a sequence valve, a one-way valve, a pressure regulating valve, an electromagnetic valve and an electromagnetic ball valve. The one-way valve is connected with an oil inlet, and the oil inlet is further connected with the proportional overflow valve, the proportional direction valve, the pressure regulating valve and the electromagnetic valve through the one-way valve. The proportional overflow valve, the proportional direction valve, the pressure regulating valve, the electromagnetic valve, the electromagnetic ball valve and the hydraulic control one-way valve are further connected with an oil return opening. The hydraulic control one-way valve and the electromagnetic ball valve can communicate with an oil cylinder piston cavity, the sequence valve can communicate with an oil cylinder rod cavity, and the electromagnetic ball valve and the sequence valve further communicate with the proportional direction valve. The intelligent control hydraulic system is simple in structure, adjustable in system pressure, accurate and simple in operation control, stable and reliable in work and convenient to popularize and use.
