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
Affiliated technical field
The present invention relates to a kind of hydraulic control valve, in particularly a kind of magnetorheological hydraulic control valve, the magnetic flow liquid passage is improved the magnetic rheological valve of the non-rectilinear fluid course of design.
Background technique
Magnetic rheological valve is compared with the conventional hydraulic control valve, and magnetic rheological valve is controlled flow by the magnetic flow liquid of valve by the size of control field coil electric current, does not have the mechanical part that moves, with respect to traditional mechanical valve, the magnetic flow liquid control valve has simple in structurely, and volume is little, be easy to control, speed of response is fast, and operational noise is low, and is wear-resistant, the reliability height, low cost and other advantages.Magnetic rheological valve is existing to be widely used.
The hydraulic control scope of magnetic rheological valve has the qualifications of itself.The flow direction of first magneto-rheological fluid in the magnetic gap space must be vertical with the direction in magnetic field; Next is the liquid chunnel of magneto-rheological fluid in the magnetic gap space.Under given boundary dimension, energy consumption, response time and given magneto-rheological fluid prerequisite, can obtain High Pressure Difference by following approach: the first is pressed the magnetic saturation intensity size of magneto-rheological fluid, place magnetic intensity maximum and be not more than the magnetic gap space of magneto-rheological fluid magnetic saturation intensity magneto-rheological fluid, make the magnetic rheology effect maximum that is produced; It two is to improve the flow channel length of magneto-rheological fluid in the magnetic gap space.In the actual design,, very difficult when realizing above two kinds of approach simultaneously because described magnetic gap space is limited.
The pressure reduction that how to improve magnetic rheological valve enlarges the hydraulic control scope of magnetic rheological valve, is the technical problem that the industry needs to be resolved hurrily.
For solving the problems of the technologies described above, Chinese patent discloses in the passage of a plurality of magneto-rheological fluids at magnetic rheological valve, the damping device (as the damp channel of damping piston, damped cylinder, damping coil control and damper etc.) of magnetic flow liquid is set, a kind of magnetic rheological valve structure is disclosed as Chinese patent, it is to form disc liquid flowing resistance passage between magnetic conduction disk and this end face, form annular liquid flowing resistance passage between the outer ring surface of magnetic conduction disk and the cylinder barrel again, be communicated with by the center hole of disc liquid flowing resistance passage, form a complete liquid chunnel with profit in-core portion.Structure although it is so can be provided with two groups or more satisfying the requirement of pressure, flow, but such structure do not utilize coil magnetic field fully and can strengthen the volume of valve, increases magnetic rheological valve assembling difficulty, rate of fault.
Summary of the invention
In order to overcome in the prior art, for increasing the damping device of the magnetic flow liquid that the magneto-rheological fluid channel resistance is provided with in the magnetic rheological valve, complex structure, increase the magnetic rheological valve volume, increase the technical deficiency of the rate of fault of magnetic rheological valve, the present invention proposes a kind of magnetic rheological valve structure of non-rectilinear fluid course, magneto-rheological fluid is flowed along the liquid chunnel non-rectilinear, thereby extended the path length that the electromagnetic current fluid flows, improved utilization ratio for the limited magnetic line of force, under magnetic gap size permanence condition, improve the size of the controlled fluid pressure reduction of electromagnetic current fluid under the equal electric current [strength, reach energy-conservation and reduce the purpose of magnetic rheological valve size.
The present invention realizes that the technological scheme that goal of the invention adopts is: a kind of magnetic rheological valve of non-rectilinear fluid course, comprise: valve body, coil brace, field coil, positioning disk and magnetic conductive disk, field coil is wrapped on the coil brace, magnetic conductive disk is arranged on the two ends of coil brace, positioning disk and magnetic conductive disk coaxial line are installed, form liquid chunnel between the corresponding end face of positioning disk and magnetic conductive disk, on the corresponding end face of described positioning disk and magnetic conductive disk, be provided with one group of concentric circle annular projection, on the end face of magnetic conductive disk, be provided with and the corresponding toroidal cavity of ring projection, ring projection and corresponding toroidal cavity, on the corresponding end face of positioning disk and magnetic conductive disk, form radially non-rectilinear fluid course.
Described positioning disk is provided with one group of pod apertures on the circumference of diameter greater than the ring projection.Described ring projection and toroidal cavity, transverse section are trapezoidal projection and trapezoidal groove.Described trapezoidal projection is different gradients with trapezoidal groove, forms the liquid chunnel that the gap changes between trapezoidal projection and the trapezoidal groove.Forming the liquid chunnel gap between the corresponding end face of described positioning disk and magnetic conductive disk is the 0.5-2 millimeter.
The invention has the beneficial effects as follows that magnetic rheological valve is simple in structure, make easy for installationly, do not increase the magnetic rheological valve volume, enlarge the control range of magnetic rheological valve.Structure of the present invention places magnetic intensity big and be not more than the magnetic gap space of magneto-rheological fluid magnetic saturation intensity magneto-rheological fluid, makes the magnetic rheology effect maximum that is produced; In limited magnetic gap space, improved the flow channel length of magneto-rheological fluid simultaneously; When having made full use of poly-magnetic cross section limited in the magnetic field, utilizing can also further poly-magnetic every the magnetic pressure circle; Require to significantly improve the pressure reduction of magneto-rheological fluid under the prerequisite at equal magneto-rheological fluid and traffic requirement, comparable size requirement, equal response time requirement, equal energy consumption.
