Networked electro-hydraulic control valve, control method and excavator
The invention discloses a networked electro-hydraulic control valve, a control method and an excavator. The networked electro-hydraulic control valve comprises a first valve body, and the first valve body is provided with an oil inlet P1, an oil return opening R1, a first main oil duct, a linear walking valve, a right walking control valve, a bucket flow collecting valve and a movable arm control valve; the second valve body is provided with an oil inlet P2, an oil return opening R2, an independent oil return opening Tk, an independent oil return opening Ta, a second main oil duct, a bucket control valve, a movable arm flow collecting valve and a first bucket rod control valve; the third valve body is provided with an oil inlet P3, an oil return opening R3, a third main oil duct, a second bucket rod control valve and a left walking control valve. All actuators are completely decoupled during independent oil source control and loading compound action of the actuators of a movable arm, a bucket rod and a bucket, the problem of energy waste caused by compound action load coupling of multiple actuators of a traditional multi-way valve is solved, and the control freedom degree is increased; a novel networked structure layout is adopted, so that the integrated design of the pump and the valve is conveniently realized; working efficiency of the control valve is improved.
本发明公开了一种网络化电液控制阀、控制方法以及挖掘机，包括：阀体一，阀体一设有进油口P1、回油口R1、第一主油道、直线行走阀、右行走控制阀、铲斗合流阀和动臂控制阀；阀体二，阀体二设有进油口P2、回油口R2、单独回油口Tk、单独回油口Ta、第二主油道、铲斗控制阀、动臂合流阀和第一斗杆控制阀；阀体三，阀体三设有进油口P3、回油口R3、第三主油道、第二斗杆控制阀和左行走控制阀。实现动臂、斗杆、铲斗各执行器独立油源控制，上车复合动作时，所有执行器完全解耦，解决传统多路阀多执行器复合动作负载耦合造成的能量浪费问题，增加控制自由度；采用新型网络化结构布局，便于实现泵阀一体化设计；提高控制阀工作效率。
