| Zusammenfassung: | A redundant quick-closing proportional valve control hydraulic servo system relates to the technical field of valve control and comprises a pressure oil pipe, a safety oil pipe, an oil discharge pipe, an execution oil cylinder, a proportional servo valve, a sequence valve, a safety oil control valve and two hydraulic control cartridge valves. The pressure oil pipe is connected to a pressure oil port of the proportional servo valve through the sequence valve, and a working oil port is connected to a first working oil port of the first hydraulic control cartridge valve and a rod cavity of the execution oil cylinder through the throttling valve and connected to a control oil port of the first hydraulic control cartridge valve through the throttling valve. A second working oil port of the first hydraulic control cartridge valve is connected to a rodless cavity of the execution oil cylinder and an oil discharge pipe; the safety oil pipe is connected to a pressure oil port of the safety oil control valve, and a wor |
