The working valve plate comprises a valve body and a valve rod, the valve body is provided with a first pressure channel and a second pressure channel which are communicated with a valve cavity, and when pressure oil is introduced into the first pressure channel, the pressure oil can push the valve rod to move; the main oil inlet channel is communicated with the first oil distribution channel; when pressure oil is introduced into the second pressure channel, the pressure oil can push the valve rod to move, so that the main oil inlet channel communicates with the second oil distribution channel; the working valve plate further comprises an electromagnetic valve assembly which is used for controlling connection and disconnection of the first pressure channel and the second pressure channel. According to the working valve plate and the electro-hydraulic proportional multi-way valve, the problems that according to an existing working valve plate, a valve rod is pushed to move in a manual mode, so that the operation comfort of the multi-way valve is low, and the control precision and the operation efficiency of the multi-way valve are reduced are solved.

    本申请涉及一种工作阀片及电液比例多路阀,本申请提供的工作阀片包括阀体和阀杆,阀体设有分别连通阀腔的第一压力通道和第二压力通道,当第一压力通道通入压力油液时,压力油液能够推动阀杆移动,以使主进油通道连通第一分油通道;当第二压力通道通入压力油液时,压力油液能够推动阀杆移动,以使主进油通道连通第二分油通道;工作阀片还包括电磁阀组件,电磁阀组件用于控制第一压力通道和第二压力通道的通断。本申请提供的工作阀片及电液比例多路阀解决了现有的工作阀片采用人工手动的方式推动阀杆移动,造成多路阀的操作舒适性较低且多路阀的控制精度和操作效率下降的问题。
