Intercepter plate device hydraulic system for ship navigation state control

The utility model discloses a hydraulic system of an intercepting plate device for ship navigation state control, which comprises two servo valve block components connected in parallel, and a starboard servo valve block component controls an oil cylinder of at least one intercepting actuating mechanism arranged on a starboard. The port servo valve block assembly controls an oil cylinder of at least one cut-off executing mechanism arranged on a port. The input end of the servo valve block assembly is connected with the hydraulic pump station, and the output end of the servo valve block assembly is connected with the oil cylinder. The servo valve block assembly at least comprises a first servo valve. Accurate hydraulic control is carried out on the oil cylinders through the servo valves, so that the intercepter plates on the left side and the right side can move synchronously and can also move in a differential mode. When pitching and trim adjustment is carried out, the intercepter plates on the left side and t
