The invention relates to an electric control multi-way valve which comprises a first valve body, a first control assembly, a motor and a controller. The first valve body is provided with a first oil return port, a first oil inlet communicated with an oil pump and an oil inlet/outlet communicated with an oil cylinder, an oil inlet/outlet way communicated with the oil inlet/outlet, the first oil return port and the first oil inlet is arranged in the first valve body, and two oil discharge ways which are respectively arranged at two ends of the oil inlet/outlet way and are communicated with the first oil return port are also arranged in the first valve body; the first control assembly comprises a valve rod slidably arranged on the oil inlet and outlet way in a penetrating mode and a driving piece arranged on the first valve body, the driving piece is used for driving the valve rod to slide in a reciprocating mode so as to control on-off of the oil inlet and outlet way, and when the valve rod slides in a reciprocating mode, pressure oil leaked from the two ends of the valve rod can be discharged from the oil discharging way. The motor is electrically connected with the oil pump and used for driving the oil pump to rotationally supply oil; the controller is electrically connected with the driving piece and the motor and can control the motor and the driving piece to operate synchronously. Therefore, the multi-way valve is protected, and meanwhile it is guaranteed that the valve rod can move smoothly.

    本发明涉及一种电控多路阀,包括第一阀体、第一控制组件、电机及控制器;第一阀体具有第一回油口、与油泵连通的第一进油口以及与油缸连通的进出油口,第一阀体内设有连通进出油口、第一回油口及第一进油口的进出油路,第一阀体内还设有分别设置于进出油路的两端且与第一回油口连通的两个排油路;第一控制组件包括滑动穿设于进出油路上的阀杆以及设置于第一阀体的驱动件,驱动件用于驱动阀杆往复滑动以控制进出油路的通断,且阀杆往复滑动时,阀杆两端泄漏的压力油液能够从排油路排出;电机电连接油泵,电机用于驱动油泵转动供油;控制器与驱动件及电机电连接,并能够控制电机与驱动件同步运作。从而在保护多路阀的同时保证阀杆能够平顺运动。
