Abstract

The invention discloses a hydraulic control valve unit for a rotating-vane type steering engine, belonging to the field of hydraulic control valve units. The hydraulic control valve unit comprises an electromagnetic reversing vale, a shuttle valve, a pilot-operated relief valve, a first cartridge valve, a second cartridge valve, a third cartridge valve, a fourth cartridge valve, a fifth cartridge valve, a sixth cartridge valve and a seventh cartridge valve; an oil inlet of the hydraulic control valve unit is communicated with a first oil inlet of the seventh cartridge valve and a first oil inlet of the electromagnetic reversing vale; a second oil inlet of the seventh cartridge valve is communicated with the oil outlet of the hydraulic control valve unit; an oil control port of the seventh cartridge valve is communicated with an oil inlet and an oil outlet of the pilot-operated relief valve; and the oil outlet of the pilot-operated relief valve is communicated with the oil outlet of the hydraulic control valve unit. The heating of a hydraulic system is reduced, thus the size of an oil tank of a hydraulic pump station is reduced, and the space in a ship is saved.

Description

technical field [0001] The invention relates to the field of hydraulic control valve groups, in particular to a hydraulic control valve group for a rotary vane steering gear. Background technique [0002] Rotary vane steering gear is a new type of steering gear widely used in various ships in the world. Its working principle is similar to that of a two-way swing blade motor. The rotation of the rotor is the output of the device. The rotor and the rudder stock are connected by interference or other means. The rotation of the rotor drives the rotation of the rudder stock, thereby realizing the motion control of the rudder blades. . [0003] The rotary vane hydraulic steering gear controls the rotation of the rotor through the hydraulic system. The hydraulic system uses multiple slide valves, internal control reversing valves and other valves to cooperate with other components in the hydraulic system to provide sufficient hydraulic energy to the steering gear. During the work...
