Magnetorheological valve of helical fluid channel

Abstract

The invention provides a magneto-rheological fluid (MRF) valve of a spiral liquid passage, which mainly solves the problem of nonlinear flow of the MRF along the liquid passage in the MRF valve, enlarges the flowing path length of the electro-magneto-rheological fluid, improves the utilization ratio of the line of magnetic force, improves the pressure difference of the controllable fluid of the electro-magneto-rheological fluid under the equivalent current intensity and unchangeable magnetic gap, and achieves the objects of saving energy and reducing the dimension of the MRF valve. The proposal of the MRF valve is that the corresponding end surface of a positioning disc to a magnetic guide disc is provided with a nonlinear liquid passage. The MRF valve has the advantages of simple structure of MRF valve, convenient manufacture and installation, increasing no volumes of the MRF valve, and enlarging the control range of the MRF valve.

Description

Technical field [0001] The invention relates to a hydraulic control valve, in particular to a magneto-rheological valve with a helical liquid flow channel designed to improve the magneto-rheological fluid channel in a magneto-rheological hydraulic control 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, 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 of the magnetorheological fluid in the mag...

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 magneto-rheological valve structure of a spiral liquid flow channel, which makes the magnetorheological fluid flow non-linearly along the liquid flow channel, thus lengthening the path length of the electromagnetic rheological fluid flow and improving the resistance to the limited magnetic field lines. Utilization rate, under the condition of constant magnetic gap size, increase the controllable fluid pressure difference of electromagnetic rheological fluid under the same current intensity, so as to achieve the purpose of saving energy and reducing the size of magnetorheological valves
