Description

Annular and radial mixed type channel magnetorheological valve
Technical Field
The invention relates to the field of magnetorheological valves, in particular to an annular and radial mixed channel magnetorheological valve.
Background
Compared with the traditional hydraulic control valve, the magnetorheological valve controls the flow of the magnetorheological fluid passing through the valve by controlling the current of the magnet exciting coil, has no movable mechanical part, and has the advantages of simple structure, small volume, easy control, high response speed, low working noise, wear resistance, high reliability, low cost and the like compared with the traditional mechanical valve and the magnetorheological fluid control valve. Magnetorheological valves are now widely used.
In engineering application, it is often required that the magnetorheological fluid has different pressure drops when the flow directions are different, and three ways are usually adopted for realizing: firstly, a controller is utilized to monitor the movement direction of liquid flow, when the liquid flow is reversed, the size of exciting current in the magnetorheological valve is changed, a control system is complex, and the temperature rise of the magnetorheological valve is aggravated by frequently changing the current; and secondly, a bypass hydraulic valve is connected in parallel to the magnetorheological valve, but the structural design has large occupied space and poor controllability. And thirdly, the pressure difference of the magnetorheological valve is changed by changing the circulation length in the magnetic gap space.
The improvement of the length of the flow channel of the magnetorheological fluid in the magnetic gap space has important influence on the increase of the pressure difference of the magnetorheological valve. We increase the pressure drop of the magnetorheological valve by changing its structure. A magnetorheological valve apparatus as described in reference 1 (publication No. CN 102691688B). However, on the one hand, the liquid flow channel has a complicated structure, especially a multi-stage serpentine type, and is particularly easy to block during operation, and on the other hand, the external dimension is too large, and the application is limited, especially in the application field with small volume. As described in reference 2 (publication No. CN 205779983U), the multistage mixed flow type magnetorheological valve with a wide pressure drop adjustment range increases an axial annular damping gap, increases an effective length of the damping gap, and does not reduce magnetic induction intensity in the damping gap, so that the pressure drop at the inlet and the outlet of the magnetorheological valve is large to some extent, but the pressure drop at the inlet and the outlet of the magnetorheological valve cannot meet the working requirement of the magnetorheological valve due to the requirement of high performance and the requirement of a larger pressure drop range.
Therefore, it is important to provide and design a magnetorheological valve with a simple structure of a liquid flow passage, small overall dimension and wide pressure difference adjustable range.
