Description
Technical field
The utility model relates to a kind of magnetic rheological valve, particularly relates to a kind of mixed flow dynamic formula magnetic rheological valve.
Background technique
In hydraulic control system, control valve is mainly used to control the pressure of liquid stream in executive component, flow and flow direction, meets the requirement of all kinds of hydraulic equipment to motion, speed, power and torque even load operating mode.Therefore the performance of hydraulic control valve directly has influence on the static state of hydraulic system, dynamic characteristic and functional reliability, is the key control unit in hydraulic control system.Along with the development of new and high technology, the requirement of hydraulicdriven engineer applied to hydraulic element is more and more higher, owing to there is movable mechanical part in traditional hydraulic control valve, not only complex structure, volume is large, processing request is high, easy wearing and tearing, cost are high, but also there is the problems such as wayward, low-response, operational noise are large, functional reliability is low.
Magnetic rheological valve is a kind of novel intelligent hydraulic control component designed for control principle with the magnetic rheology effect of magnetic flow liquid.Regulated the pilot pressure of magnetic rheological valve by the size changing applied field strengths, realize the intelligent control of magnetic rheological valve.Because magnetic rheological valve does not have moveable mechanical part, valve inlet and outlet pressure can be controlled by impressed current, therefore fast response time, noise is low, energy consumption is little, working stability is reliable, has good prospects for commercial application.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises: left end cap (1), diversion disk (2), seal ring I (3), screw I (4), seal ring II (5), seal ring III (6), magnetic conduction disk (7), packing ring (8), counterbore screw (9), seal ring IV (10), positioning disk (11), valve body (12), seal ring V (13), right end cap (14), seal ring VI (15), coil (16), spool (17) and screw II (18).
During assembling, first positioning disk (11) is loaded onto seal ring IV (10), then be threaded connection guarantee axial distance with spool (17); Then coil (16) is around in the winding slot that positioning disk (11) and spool (17) formed, finally two of the coil twined wires is drawn from the 2mm circular hole on spool (17) top, right side.Magnetic conduction disk (7) is fixedly connected with by four counterbore screws (9) with positioning disk (11), and packing ring (8) ensures that axial clearance is between the two 1.5mm.Structure after magnetic conduction disk (7), positioning disk (11) and spool (17) connect and valve body (12) cooperatively interact, and ensure that the radial clearance between magnetic conduction disk (7) and valve body (12) is 1mm.Right end cap (14) installs seal ring V (13) and seal ring VI (15), 2mm fairlead set by the 2mm circular hole on spool (17) top, right side and right end cap (14) is aligned, two winding wires are passed from right end cap (14).Then right end cap (14), spool (17) and valve body (12) are fixedly connected with by screw II (18).Diversion disk (2) installs seal ring III (6), and with valve body (12) Spielpassung.Left end cap (1) installs seal ring I (3) and seal ring II (5) respectively, and left end cap (1), diversion disk (2) and valve body (12) are fixedly connected with by screw I (4).
Left end cap (1) left end inlet has attacked outside thread, directly can be threaded with hydraulic tubing; Outside thread has been attacked in right end cap (14) right-hand member outlet port, directly can be threaded with hydraulic tubing.
Figure 2 shows that magnetic conduction disk (7) plan view.Figure 3 shows that the utility model magnetic line of force distribution schematic diagram, in figure, magnetic conduction disk (7), valve body (12) and spool (17) are low carbon steel permeability magnetic material, remaining parts is non-magnet_conductible material, and therefore the magnetic line of force can pass perpendicularly through axial and radial damping clearance.
Figure 4 shows that the utility model magnetic flow liquid liquid chunnel and damping clearance schematic diagram.Damping clearance is divided into two-part, first portion is the axial damping clearance formed by magnetic conduction disk (7) and valve body (12), and second portion is the radial damping clearance surrounded by magnetic conduction disk (7), valve body (12) and spool (13).Because the utility model is axially symmetric structure, this structure upper half part gives the liquid chunnel of magnetic flow liquid in mixed flow dynamic formula magnetic rheological valve, and lower half portion then gives the effective working zone of damping clearance of mixed flow dynamic formula magnetic rheological valve.
Utility model works principle is as follows:
As shown in Figure 1, Figure 3 and Figure 4, when passing into a certain size electric current to coil (16), because magnetic conduction disk (7), valve body (12) and spool (17) are low carbon steel permeability magnetic material, and remaining parts is non-magnet_conductible material, the magnetic line of force formed because of electromagnetic effect forms closed-loop path through magnetic conduction disk (7), valve body (12) and spool (17).The magnetic line of force both perpendicular to the axial damping clearance that magnetic conduction disk (7) and valve body (12) are formed, again perpendicular to the radial damping clearance that magnetic conduction disk (7), valve body (12) surround with spool (17).
When giving coil (16) energising, due to magnetic fields, its viscosity of magnetic flow liquid that is axial and radial damping clearance can increase, and yield stress strengthens.Magnetic flow liquid flows through this two damping clearances, just must overcome the intermolecular power of this catenation, thus the resistance causing magnetic flow liquid to flow through valve increases, and can slow down or stop the flowing of liquid, thus produces pressure difference.By size of current in regulating winding, the yield stress of magnetic flow liquid can be changed, poor to reach required inlet and outlet pressure.
