The electro-hydraulic conversion valve is provided with a bus pilot driving module, a first-stage amplification valve element, a second-stage amplification valve element, a main reversing valve element, a steering buffering oil suction valve, an LS dynamic control valve, an LS overflow valve, a steering priority valve and a pressure reducing valve. The steering of the engineering machinery can be controlled by an electric control handle, remote control operation and unmanned operation. The steering responsiveness of the system can be improved, the matching difficulty of the system is reduced, and pipelines of the hydraulic system are simplified; steering action operation is changed from steering wheel control to electric control handle, operation force is small, response is fast, comfort is better than steering wheel steering, operation is flexible, and operation is more efficient and stable.

    本发明公开了一种电液转向阀及其系统、控制方法,电液转向阀设置总线先导驱动模块、一级放大阀芯、二级放大阀芯、主换向阀芯、转向缓冲吸油阀、LS动态控制阀、LS溢流阀、转向优先阀和减压阀,可以实现电控手柄、遥控操作和无人化操作控制工程机械转向。本发明可以提升系统的转向响应性,降低系统匹配难度,简化液压系统的管路;转向动作操作由操控方向盘更换为电控手柄,操作力小,响应快,舒适性优于方向盘转向,操纵灵活,更高效稳定。
