Description
Technical field:
The present invention relates to a kind of multi-functional flow control valve, belongs to hydraulic, pneumatic component and petrochemical industry, chemical industry, fluid are defeated
Send control technology field.Flow control valve is a kind of very widely used, particularly important base components, is commonly referred to as throttling
Valve, regulating valve have different form and specification according to application, operating condition purpose, the difference of technical requirements.
Background technique:
In the automatic control of modern plant, regulating valve is played a very important role, and the production of these factories is depended on
It correctly distributes and controls in the medium flowed.Automatically control either the exchange of energy, assignment of traffic, pressure reduction or
It is simple container charging, requires flow control set for adjusting to complete.In industry spot, the instrument system of fluid flow is measured
Referred to as flowmeter or flowmeter.It is one of most important instrument in commercial measurement.With the development of industry, to the standard of flow measurement
Exactness and area requirement are higher and higher, it can be considered that it is industry automatic control that flow, which adjusts control, measurement and instant playback,
Or even the important proposition of intelligent control.
Throttle valve in the prior art, or be regulating valve, it is by changing throttling section or chock length to control fluid
The valve of flow is depended not only on the size of choke area by the flow of throttle valve, also had with the pressure difference before and after restriction
It closes, its right principle changes liquid resistance in a manner of throttling all to carry out flow control.Medium flow velocity between throttling flap and valve seat
Very big, to cause these piece surfaces to be quickly damaged-i.e. so-called cavitation, cavitation, throttling makes liquid resistance increase can be changed and passes through
The flow of valve, but energy loss also is brought simultaneously, and being converted into thermal energy makes fluid and valve heat up, its shadow for system
It rings undoubtedly negative.Especially in hydraulic transmission technology field, caused by throttling serious " fever " and " energy loss "
It is belong to " principle " consequence, therefore, is examined closely from the idea of energy-saving and emission-reduction, it has also become restriction technologies development, application
Bottleneck.However, regrettably, in control this important technology field of fluid flow, the prior art continues to use a century but always
" slit " formed between " spool ", " valve seat " is not walked out." variable pump control, the circuit for adjusting flow " " volume variable displacement circuit "
It is an important breakthrough in theory, opens the completely new visual field, thinking, but due to not having to introduce the concept of " valve ", do not have
To form independent component, thus be not affected by due care, application cannot popularize, lagging in development.In such prior art
Under background, the present invention proposes a kind of " multi-functional flow control valve ".
The innovation of " multi-functional flow control valve " is that the theory by " flow controlling unit " applies to " valve ",
And by the Conceptual Extension of " valve " into the function element that can be realized " flow adjusting ".For giving an actual example: in the prior art oblique
Disc type shaft orientation plunger variable pump, is a kind of device that rotating mechanical energy is converted into fluid dynamic energy, and discharge capacity, that is, swept volume
It is adjustable.When discovery, this device is reversible, and when fluid dynamic energy can also be converted into rotating mechanical energy by it, there is a change
Purposes, for the innovation of another purpose, i.e. variable displacement motor.Then the identical device of this essential structure is expressed as " swash plate
Formula shaft orientation plunger variable pump/motor ".Now, by its Function Extension to the field of " valve ", undoubtedly functionally have more not
Same requirement, will have different understanding to working principle, the mechanism of its structure, be one for being bigger leap in its purposes
Kind breaks through the important innovations of idea, can be expressed as " oblique tray type axial plunger piston variable pump/motor/valve ".Obviously, thing, which is also not, adds
One "/" slash is so simple, if common oblique tray type axial plunger piston variable pump in the prior art serves as flow control valve and is connected in series to
It is required carry out flow control circuit in, be in principle it is feasible, still, in the work course, inlet pressure is converted into column
The linear motion mechanical energy of plug；The rotating mechanical energy of cylinder body is converted by acting on swash plate again；Then in the other side of swash plate
The rotating mechanical energy of cylinder body is converted into the linear motion mechanical energy of plunger again；The linear motion of plunger is converted into fluid pressure energy
Form outlet pressure.It can be seen that very big energy loss will be brought by repeatedly converting repeatedly, or perhaps the pressure loss.Meanwhile becoming
Although measuring mechanism can be directly changed discharge capacity, because driving inertia is big, respond insensitive without adapting to want as flow control
It asks.In the prior art there are also " traditional hydraulic transformer ", " novel hydraulic transformer " technology, product, thinking, effect,
Principle is substantially similar with previous examples, but yet still in research and development, and not up to theoretical mature, the widely applied rank of technology
Section.
Still there is a kind of volume to add up the flow measurement device of formula in the prior art, utilizes the orthobaric volume space of moving element
Continuously measure fluid total measurement (volume).This flowmeter for fluid displacement metering like bucket amount, with the rotation of moving element,
The medium flowed through is accommodated to orthobaric volume space cycle, the total capacity for flowing through medium can be measured according to metering numbers.Example is such as:
Applied to single-piston flowmeter, four piston meters in fuel charger, using gas (liquid) cylinder as measuring room, piston is measurement member
Part, piston can be reciprocating in cylinder, and under the action of importing and exporting fluid differential pressure, fluid enters cylinder through reversal valve from entrance
It is interior, piston motion is pushed, metering is completed.
There is application for a patent for invention " a kind of curved surface raceway sloping tray axial plunger piston pump and motor " in person before this,
ZL201510295059.2, i.e., double valve plate axial plunger pump/motors, swash plate variation is two-way curved surface raceway, is increased
By plunger guide and the guide assembly of torque is transmitted, and workpiece is that double end plunger is constituted with the coupled column plug cylinder for being located at both ends
Dual action axial to plunger case, double valve plates are to from both ends to dual action axial to plunger case flow, the base of this prior art
This construction is core of the invention and basis.Mechanism about flow control, adjusting can be referring to a kind of [double valve plate axial plungers

Summary of the invention:
The object of the present invention is to provide a kind of non-hydraulic resistance flow control valves of nothing " spool, valve seat ", while also having both stream
Amount monitoring, function of measuring；Shut-off valve and repid cut-off valve function；" the multi-functional flow control valve " of pipe pressurizing pumping function.
The unique texture of curved surface raceway sloping tray axial plunger piston pump/motor and the application of working principle are " multi-functional flow controls
The core technology of valve processed ".Concrete analysis: Fig. 3 is flow control valve, and core institution is exactly " curved surface raceway sloping tray axial plunger piston
Pump/motor ", its visible main working parts are to have the dual action axial of coaxial double end plunger (3-10) to plunger case in figure, into
Mouthful pressure, which can be applied to rigid plunger and be directly delivered to outlet, forms outlet pressure.Import has pressure difference to outlet, is because " laterally
Roller bearing " (3-8) and left curved surface raceway (3-6), right curved surface raceway (3-12) effect generate turning moment and seldom energy have been lost
Amount.It is each configured with left and right movable valve plate (3-5), (3-14) at the both ends of rotor (3-7), effect is matched to plunger case
Stream.Setting the original state flow passed through not being adjusted is the flow gain of left and right valve plate relative to left and right curved surface
Raceway (3-6), (3-12) upper and lower dead point between line it is symmetrical；Upper left corner interface and lower right corner interface connection, and make
For fluid inlet, the high pipeline of pressure is connect, and lower left corner interface and upper right corner interface connection are outlet, are serially connected in pipeline and control
The flow of the medium flowed through, the right and left is two hydraulic motors for coaxial linkage in no output torque in terms of middle separated time at this time
In the state of load will high speed no-load running, therefore should be with load or having certain back pressure that can transport safely in outlet end
Row.In terms of longitudinal axis, as previously mentioned, inlet pressure is directly delivered to outlet to plunger case by each dual action axial, when
Import accesses constant pressure, is for the maximum under the state when pressure difference, load, flow reach stable equilibrium as Secondary Control element
Flow, energy loss and liquid resistance will be significantly smaller than conventional throttle valve.
It when carrying out flow adjusting, needs to rotate valve plate, such as right movable valve plate (3-14) is rotated clockwise a certain
Angle, then left and right movable valve plate (3-5), (3-14) flow gain corresponding position be varied so that " dual action axial to
Its plunger both ends can connection import simultaneously when rotating to a certain region with rotor (3-7) for plunger case "；And in its rotational symmetry
It another region plunger both ends can connection outlet simultaneously.Double end plunger is in damped motion state at this time, will be in import high pressure flow
A part feed back to import flow gain, and rate of discharge also can be reduced accordingly and compensate plunger low-pressure end.When right activity
When valve plate (3-14) turnback clockwise, it is left and right activity valve plate (3-5), (3-14) flow gain import and export double
Headpin plug both sides position is all overlapped, and will not have the flow output and input, also there is no torque, rotor will stop operating.
That is a movable valve plate rotation, from 0-180 degree controllable flow rate from being up to 0 output.It is worth noting that when
When left and right activity valve plate (3-5), (3-14) all carry out rotation adjustment position, situation can be more complicated, and there are two not Tongfangs for meeting
To torque simultaneously act on rotor, this for adjustment rotor speed so that adjust flow be effective.The example lifted such as front
Son, a common cam-type axial piston variable displacement motor in the prior art, that is, may act as flow control valve be connected in series to needed for into
In the circuit of row flow control, flow control valve of the invention actually can be considered " valve in parallel " of two coaxial linkages, when
This two deck valve is connected in series in the rotary actuator circuit for respectively needing to control, then can to two rotary actuators respectively and simultaneously into
Row speed control, and the outlet of two valves to the total flow together, then provided jointly will be executed in two rotations in parallel
Flow is distributed automatically according to its payload size in device, different speed is obtained, is equivalent to the effect of differential mechanism.Therefore, multi-functional
Flow control valve will become the first choice of quantitative hydraulic wheel motor speed control valve in vehicle to run hydraulic-driven scheme.It is more
It is of wide application function flow control valve, particularly with the actuator such as hydraulic cylinder of " effective active area is immutable " etc. into
Row speed control will play energy saving, accurate, convenient irreplaceable role, its certain technical characteristic needs to be excavated, optimize.But
Various operating conditions, state be such as: negative load, minus flow, energy regenerating, additional functional elements are excessively cumbersome, do not discuss herein.
A kind of multi-functional flow control valve is made of curved surface raceway sloping tray axial plunger piston motor, control driving part, and general
Logical sloping tray axial plunger piston pump/motor is different, and swash plate variation is two-way curved surface raceway, increases plunger guide and transmits torsion
The guide assembly of square, and workpiece is the dual action axial of double end plunger opposed with two assembled hydraulic cylinder composition to plunger case,
Double valve plates are to from both ends to dual action axial to plunger case flow, it is characterised in that: double valve plates are that is, left activity flow
Disk (3-5), right movable valve plate (3-14) are placed on left connector sleeve (3-4), in right connector sleeve (3-13), the connection respectively
Covering inner circle, there are two annular channel (3-25) respectively, have sealing element with outside therebetween, can also be in the connector sleeve and the flow
Clearance seal is formed between disk, the annular channel connects external port, and there are two flow waists respectively for the bottom surface of double valve plates
Slot (3-28), the outer cylinder surface that each flow gain has inner passage to be connected to the valve plate, position corresponds to
The annular channel of the connector sleeve, double valve plates tops are provided with internal gear (3-26) and the control driving part

The only function of valve, repid cut-off valve, blower pump for pipeline.The function of most of component, effect have had a detailed description in the body of the email, special
It is other to be provided with driving motor deceleration, clutch (11), driving motor (12), brake (9), wherein driving motor deceleration,
Auxiliary body of the clutch (11) as driving motor (12), function are obvious.It, can be immediately by main shaft when brake (9) movement
(7) it brakes, rotor (13) stops operating and exports without flow, plays the role of repid cut-off valve.Especially setting driving motor
It (12) is to make flow control valve have more functions and superior technique characteristic will especially in fluid pipeline transportation art
More important function can be played.Flow control valve of the invention is its working principle is that non-slit throttling hydraulic resistance as previously described, and
It is to achieve the purpose that adjust flow by changing volume and changing revolving speed.In fact it is closer for changing the mode of revolving speed
Valve is allowed to operate in higher revolving speed work when we directly connect flow and rotor speed in the principle for increasing liquid resistance
The volume of condition, valve can reduce, and changing simultaneously discharge capacity also becomes not too important, and rotor speed is only adjusted without volume adjustment
And it recycles rotating mechanical energy and flow adjusting can be realized.Therefore four kinds of states of driving motor (12): 1. clutches can be set
Separation.2. the rotation loss of small power backoffs rotor, aneroid hinder normal discharge.3. high-power operating speed-raising pressurization, increases flow.4.
Negative work damping state adjusts flow and recovers energy.
As it can be seen that the form of flow gain (28) and design in the prior art have a little variation, i.e., by original in attached drawing
The arc groove of even width change into fish shape, this is desirable to reduce impact, vibration and noise by changing runner, in fact only
It is the extending design of damping triangular groove in the prior art.
