Abstract

A MRF valve for non-linear flow channel mainly solves the problem that the magneto-rheological fluid conducts non-linear flow along the flow channel in the MRF valve. The MRF valve prolongs the flowing path length of the magneto-rheological fluid, improves the utilization rate of the magnetic line and increases the pressure difference of the controllable fluid of the magneto-rheological fluid under the same current intensity, thus achieving the aim of saving energy and reducing the size of the MRF valve. The technical scheme is to arrange a non-linear flow channel on the corresponding end surface of a positioning plate and a magnetic conductive disk. The MRF valve has advantages of simple structure, convenient manufacture and installation; the control range of the MRF valve is expanded without increasing the size of the MRF valve.

Description

Technical field [0001] The invention relates to a hydraulic control valve, in particular to a magnetorheological hydraulic control valve, an improved design of a magnetorheological fluid channel for a non-linear fluid flow channel magnetorheological valve. Background technique [0002] Compared with traditional hydraulic control valves, magnetorheological valves control the flow of magnetorheological fluid through the valve by controlling the magnitude of the excitation coil current. There are no moving mechanical parts. Compared with traditional mechanical valves, the magnetorheological valve controls the flow of magnetorheological fluid through the valve. The variable liquid control valve has the advantages of simple structure, small size, easy control, fast response speed, low operating noise, wear resistance, high reliability, and low cost. Magnetorheological valves are now widely used. [0003] The hydraulic control range of the magnetorheological valve has its own limitatio...
