Description
Technical field
The present invention relates to a kind of check valve, especially relate to a kind of check valve based on magnetic rheology effect.
Background technology
Hydraulic executing system is not only widely used in civilian machining, vehicle and building trade, and space flight, aviation and
War products have also been obtained and be widely applied.Hydraulic control valve is as one of the key control unit of hydraulic actuator, always
Directly influence the static characteristic of hydraulic actuator, dynamic characteristic and its functional reliability.Inside traditional hydraulic control valve
Owing to there is more moving mechanical member, not only structure is complicated, volume is big, processing request is high, easy abrasion, cost are high, and
And there is also the problems such as wayward, low-response, work noise big, functional reliability is the highest.Therefore seek a kind of simple in construction,
Reliable in action, easily controllable, respond fast hydraulic control valve be hydraulic actuator be eager solve problem.
Magnetic flow liquid is made up of micron order ferromagnetic particle, base fluid, additive.Under the conditions of zero magnetic field intensity, magnetic current
Become liquid and show as good fluidity, the New ton fluid that viscosity is low, under conditions of having externally-applied magnetic field, the instantaneous (millisecond of magnetic flow liquid
Magnitude) to high viscosity, the Bingham transitional fluid of lazy flow.Research shows that the shear yield stress of magnetic flow liquid can reach
50-100KP, operating temperature range is between-40 DEG C-150 DEG C, and the Reversible Cycle change frequency of magnetic flow liquid is about 3,000,000
Secondary.
Being operated under shear mode, the damping force of magnetic flow liquid can calculate by below equation:
In formula: η is viscosity (slope of shear stress after the surrender of actual measurement) after the liquid surrender unrelated with magnetic field intensity；v
Shear strain rate for fluid；τyFor mangneto shear yield stress；Sgn (v) is in view of the reciprocating motion of piston.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of check valve based on magnetic rheology effect.Device is mainly used in essence
Fluid flow direction in close hydraulic control system and the control of the break-make of oil circuit, by controlling electric current in inflow solenoid
Size regulate the shear yield stress of magnetic flow liquid, and then the pressure that spool can be forced to reach surrender is carried out electrodeless tune
Joint, has the advantages such as simple in construction, reliable in action, easily controllable, response is fast.
In order to effectively realize function as above and feature, the present invention realizes as follows: this device
Mainly by valve body, bolt, valve pocket, solenoid, valve end cap, magnetic flow liquid, cage ring, sealing ring, spool forms.Valve body,
It is bolted between valve pocket, valve end cap；Valve core inside has oil circuit, and outside has annular groove, and solenoid is wound on this annular groove
The inside；Spool becomes matched in clearance with valve pocket, and its gap is full of magnetic flow liquid, and is sealed against by sealing ring, magnetic flow liquid with
Solenoid is isolated by cage ring；Having annular groove inside valve pocket two ends, sealing ring is embedded in inside this annular groove.
A kind of having the active effect that of check valve based on magnetic rheology effect of the present invention is mainly used in precise hydraulic
Fluid flow direction in control system and the control of the break-make of oil circuit, by controlling to flow into the size of electric current in solenoid
Regulate the shear yield stress of magnetic flow liquid, and then the pressure that spool can be forced to reach surrender is carried out electrodeless regulation, have
The advantages such as simple in construction, reliable in action, easily controllable, response is fast.
Accompanying drawing explanation
Fig. 1 is the internal structure principle schematic of a kind of check valve based on magnetic rheology effect of the present invention.
Detailed description of the invention
The present invention is described in more detail with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of check valve based on magnetic rheology effect of the present invention, this device mainly by valve body 1, bolt 2,
Valve pocket 3, solenoid 4, valve end cap 6, magnetic flow liquid 7, cage ring 8, sealing ring 9, spool 10 form.Valve body 1, valve pocket 3, valve end
Fixed by bolt 2 between lid 6；Spool 10 is internal has oil circuit 5, and outside has annular groove, and solenoid 4 is wound in this annular groove
Face；Spool 10 becomes matched in clearance with valve pocket 3, and its gap is full of magnetic flow liquid 7, and is sealed against by sealing ring 9, magnetic flow liquid
7 are isolated by cage ring 8 with solenoid 4；Having annular groove inside valve pocket 3 two ends, sealing ring 9 is embedded in inside this annular groove.
Solenoid 4 is connected with the electric current of some strength, thus forms envelope between valve pocket 3, magnetic flow liquid 7 and spool 10
The magnetic loop closed so that magnetic flow liquid 7 has certain shear yield stress, when fluid is by valve as illustrated by the arrows in fig. 1
Entrance 11, thus spool end a is had certain hydraulic coupling, when this pressure is less than the pressure that spool 10 can be forced to produce motion
During power, spool 10 keeps resting state, valve to remain closed, and fluid is obstructed, when more than spool 10 can be forced to produce motion
During pressure, spool 10 moves, and valve is opened, and fluid flows out valve as illustrated by the arrows in fig. 1 by the oil circuit within spool 10
Outlet, and the shear yielding of magnetic flow liquid 7 can be controlled by the size controlling to flow into the electric current in solenoid 4 should
Power, and then control the pressure that spool 10 can be forced to produce motion, it is carried out electrodeless regulation.
