2D high-speed reversing valve used for electro-hydraulic vibration excitation device

The invention relates to the technical field of 2D hydraulic valves, and particularly discloses a 2D high-speed reversing valve used for an electro-hydraulic vibration excitation device. The 2D high-speed reversing valve comprises a rotating motor, a coupler, a coupler mounting seat, a sealing port, a spring bushing, a return spring, a thrust bearing, a valve element, a valve sleeve, a valve body,a linear motor shaft sleeve and a linear motor. According to the 2D high-speed reversing valve used for the electro-hydraulic vibration excitation device, the rotating motor drives the valve elementto rotate to achieve high-frequency reversing to achieve frequency modulation of the vibration excitation device, the linear motor drives the valve element to axially move to adjust the opening degrees of related valve ports, vertical deviation of vibration excitation waveforms of the vibration excitation device is controlled, the vibration excitation device is easy to adjust, and a hydraulic system is simplified. 本发明涉及2D液
