2D HIGH-SPEED REVERSING VALVE FOR ELECTRO-HYDRAULIC EXCITATION DEVICE

The present invention relates to the technical field of 2D hydraulic valves, and specifically discloses a 2D high-speed reversing valve for an electro-hydraulic excitation device. The 2D high-speed reversing valve includes a rotary motor, a coupler, a coupler mounting base, a sealing port, a spring bushing, a return spring, a thrust bearing, a valve spool, a valve sleeve, a valve body, a linear motor shaft sleeve, and a linear motor. The 2D high-speed reversing valve for an electro-hydraulic excitation device of the present invention realizes high frequency reversing by means of rotation of a valve spool driven by the rotary motor, so as to realize frequency modulation of the excitation device, and adjusts an opening size of a related valve port by means of an axial movement of the valve spool driven by the linear motor, so as to realize control of a vertical offset of an excitation waveform of the excitation device. In this way, the excitation device is convenient to adjust and a hydraulic system is simplified.
