Description
Technical field
The utility model relates to a kind of magnetic rheological valve, particularly relates to a kind of magnetic rheological valve with radial flow and annulus stream.
Background technique
In hydraulic control system, generally control the pressure of liquid stream in executive component, flow and flow direction with control valve, meet the requirement of all kinds of hydraulic equipment to motion, speed, power or 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 core place in hydraulic control system.Along with the development of new and high technology, in engineer applied, require more and more higher to the control valve in hydraulic system, and owing to there is movable mechanical part in traditional hydraulic control valve, not only complex structure, volume is large, processing request is high, easily wear and tear, 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 intellectual material magnetic flow liquid.Regulated the pilot pressure of magnetic rheological valve by the size changing applied field strengths in real time, realize the intelligent control of magnetic rheological valve.Because magnetic rheological valve does not have moveable mechanical part, valve inlet and outlet pressure is 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.
When carrying out magnetic rheological valve structural design, the flow direction of magnetic flow liquid in magnetic rheological valve damping clearance first should be made mutually vertical with magnetic direction; Next is that the liquid chunnel making magnetic flow liquid in magnetic rheological valve inside as far as possible lengthens.What magnetic rheological valve designed at present adopted mostly is single circular ring type liquid flow damping passage, and is the adjustable extent being improved magnetic rheological valve inlet and outlet pressure difference by following two kinds of methods.One is under identical input current, improves the magnetic induction intensity in damping clearance as far as possible in magnetic flow liquid saturation range.Conventional method is the damping clearance width reducing magnetic rheological valve, but is long placed in not with when again enabling due to magnetic flow liquid, easily occurs particle precipitation thus blocks damping clearance, causing magnetic rheological valve to lose efficacy.Second is exactly the length improving damping clearance, but significantly can increase the volume of magnetic rheological valve like this, and take more installing space, manufacture cost is corresponding increase also.
Based on this, in actual design process, want to increase the magnetic induction intensity in damping clearance simultaneously and improve the length in effective damping gap more difficult.Therefore, design a kind of stable performance and the magnetic rheological valve of structure relative compact, make that the inlet outlet pressure differential of magnetic rheological valve is larger, pressure control range is wider, being the problem that the industry needs solution badly, is also the prerequisite widening magnetic rheological valve commercial Application further.

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: seal ring I (1), left end cap (2), screw I (3), valve pocket (4), magnetic conduction disk (5), counterbore screw (6), packing ring (7), seal ring II (8), positioning disk (9), screw II (10), spool (11), right end cap (12), seal ring III (13), coil (14).
During assembling, first positioning disk (9) is loaded onto seal ring II (8), be then threaded connection guarantee axial distance with spool (11); Then coil (14) is around in the winding slot that positioning disk (9) and spool (11) formed, finally two of the coil twined wires is drawn from the 2mm circular hole on spool (11) top, right side.Magnetic conduction disk (5) is fixedly connected with by four counterbore screws (6) with positioning disk (9), and packing ring (7) ensures that axial clearance is between the two 1.5mm.Structure after magnetic conduction disk (5), positioning disk (9) and spool (11) connect and valve pocket (4) cooperatively interact, and ensure that the radial clearance between magnetic conduction disk (5) and valve body (4) is 1mm.Right end cap (12) installs seal ring seal ring III (13), 2mm fairlead set by the 2mm circular hole on spool (11) top, right side and right end cap (12) is aligned, two winding wires are passed from right end cap (12).Then right end cap (12), spool (11) and valve pocket (4) are fixedly connected with by screw II (10).Left end cap (2) installs seal ring I (1), and left end cap (2) is fixedly connected with by screw I (3) with valve pocket (4).Left end cap (2) left end inlet has attacked outside thread, directly can be threaded with hydraulic tubing; Outside thread has been attacked in right end cap (12) right-hand member outlet port, directly can be threaded with hydraulic tubing.
Figure 2 shows that magnetic conduction disk (5) plan view.Figure 3 shows that the utility model magnetic line of force distribution schematic diagram, in figure, magnetic conduction disk (5), valve pocket (4) and spool (11) are No. 10 steel permeability magnetic materials, 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 (5) and valve pocket (4), and second portion is the radial damping clearance surrounded by magnetic conduction disk (5), valve pocket (4) and spool (11).Because the utility model is axially symmetric structure, this structure upper half part gives the liquid chunnel of magnetic flow liquid in magnetic rheological valve, and lower half portion then gives the effective working zone of damping clearance of the magnetic rheological valve with radial flow and annulus stream.
Utility model works principle is as follows:
As shown in Figure 1, Figure 3 and Figure 4, a certain size electric current is passed into coil (14), because magnetic conduction disk (5), valve pocket (4) and spool (11) are No. 10 steel permeability magnetic materials, the magnetic line of force formed because of electromagnetic effect forms closed-loop path through magnetic conduction disk (5), valve pocket (4) and spool (11).The magnetic line of force both perpendicular to the annulus liquid chunnel that magnetic conduction disk (5) and valve pocket (4) are formed, again perpendicular to the radial flow of liquid passage that magnetic conduction disk (5), valve pocket (4) surround with spool (11).
During coil (14) energising, due to magnetic fields, its viscosity of magnetic flow liquid that is radial and annulus liquid chunnel place can increase, and yield stress strengthens.Magnetic flow liquid flows through this two passages, 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.
