Abstract

The invention discloses an implementation method of an electric proportional control hydraulic multi-way valve. One end of each reversing unit of the multi-way valve is respectively provided with an electric proportional hydraulic control device, the electric proportional hydraulic control device converts rotary motion into linear motion which is in proportional correspondence with the rotary motion through a driving unit; and then the electric proportional hydraulic control device carries out power amplification on signals provided by the driving unit through a servo hydraulic unit and then drives a main valve element of the multi-way valve, and electric proportional control over multi-way valve is achieved. According to the electric proportional control hydraulic multi-way valve obtainedthrough the technical scheme, the problems that an existing electric proportional multi-way valve is high in implementation cost, complex in control algorithm and not prone to large-area applicationand popularization can be solved.

Description

technical field [0001] The invention belongs to the technical field of electro-hydraulic servo control of a hydraulic multi-way reversing valve, and mainly relates to a proportional multi-way reversing valve under centralized control in a hydraulic system, in particular to a method for realizing an electric proportional control hydraulic multi-way valve. Background technique [0002] The multi-way reversing valve (referred to as the multi-way valve) is a control valve group widely used in the hydraulic system of mobile machinery, which controls the reversing of hydraulic actuators (such as hydraulic cylinders), so that the hydraulic oil in the hydraulic system controls the movement of the actuators. The device for the direction and speed of movement; because it can combine various valves according to the requirements of different hydraulic systems, it has the advantages of compact structure, simple pipeline, small pressure loss, large flow rate, and convenient installation. I...
