The invention relates to the technical field of fluid transmission and control digitization, in particular to a rotor valve core of a hydraulic 1D digital rotary valve, which is characterized by comprising a mandrel, a motor stator and an angular displacement sensor, one part of the core shaft is a motor rotor shaft, the other part of the core shaft is provided with a valve hole, the surface of the core shaft at the valve hole is provided with a plurality of grooves, the motor rotor shaft is coaxially matched with the motor stator, and the valve hole is matched with the valve sleeve; after the valve hole is matched with the valve sleeve, any logic control valve circuit of a two-position two-way valve core, a two-position three-way valve core, a two-position four-way valve core or a three-position four-way valve core is formed; the mandrel and the motor stator can form any one structure of a servo motor, a servo stepping motor or a rotary electromagnet, and digital control is achieved under the action of a control system. Compared with the prior art, the driving motor rotor and the rotor valve element are of an integrated structure, the structure is compact, the size and the weight are reduced, the assembly process is simplified, and the control precision and the response speed are improved.
Description
technical field [0001] The invention relates to the technical field of fluid transmission and control digitization, in particular to a rotor valve core of a hydraulic 1D digital rotary valve. Background technique [0002] Hydraulic valve products are widely used in fluid control in various technical fields. Currently, the visible hydraulic rotary valve spools are one-dimensional and two-dimensional. The Chinese invention patent with the application number 201310079796.X discloses a direct-feed digital hydraulic valve, including a command motor, a spline pair, a valve body, a spool, a feedback thread pair, and a feedback motor. The command motor communicates with the valve through the spline pair The core is connected; the feedback motor is connected to the valve core through the feedback thread pair, and the valve core can be converted into axial sliding through the feedback thread pair in the valve body to control the opening of the valve port. The Chinese invention patent...
