MR valve of non-rectilinear fluid course

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 magneto-rheological valve in a magneto-rheological hydraulic control valve, which is a magneto-rheological valve with a non-linear liquid flow channel designed to improve the magneto-rheological fluid channel. 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, magnetic flow The variable fluid control valve has the advantages of simple structure, small size, easy control, fast response, low working noise, wear resistance, high reliability, and low cost. Magneto-rheological valves are now widely used. [0003] The hydraulic control range of magneto-rheological valves has its own limitations. One is that the flow direction o...

Problems solved by technology

[0006] In order to overcome in the prior art, the damping device of the magnetorheological fluid provided to increase the resistance of the magnetorheological fluid channel in the magnetorheological valve has a complex structure, increases the volume of the magnetorheological valve, and increases the failure rate of the magnetorheological valve. Insufficient technology, the present invention proposes a magnetorheological valve structure with a non-linear liquid flow channel, so that the magnetorheological fluid flows non-linearly along the liquid flow channel, thereby lengthening the path length of the electromagnetic rheological fluid flow and improving the resistance to the limited magnetic field lines. Under the condition that the size of the magnetic gap remains constant, the controllable fluid pressure difference of the electromagnetic rheological fluid under the same current intensity can be increased to achieve the purpose of saving energy and reducing the size of the magnetorheological valve.
