Embodiment
The present invention is described in more detail with reference to the accompanying drawings and detailed description.
The industrial bionical valve high frequency response one-way flow of the present invention opens and closes valve can be with respect to folding including at least two
Film valve 1, the gap between film valve 1 are the passage for fluid circulation, and combination forms dome-shaped structure or pyramid to film valve 1 between each other
The top direction of shape structure, dome-shaped structure or pyramid-shaped structures is consistent with fluid flow direction.
As shown in Fig. 1~Fig. 4, when film valve 1 is two, the substantially flap shape of film valve 1, the top margin of two film valves 1 is mutual
Against the dome-shaped structure of formation.
As shown in Fig. 5~Fig. 8, when film valve 1 is three, film valve 1 is have a generally triangular shape, and the side of three film valves 1 is successively
Against formation pyramid-shaped structures.
Certainly, described film valve can also be four even more, and the side of all film valves is successively against formation pyramid
Shape structure.
Each film valve 1 is each attached on a film valve seat 3, and film valve seat 3, which is sequentially connected, encloses cyclic structure, the cyclic structure
With an opening, during liquid forward flow, liquid firstly flows through the opening, and then liquid applies pressure to the belly of film valve 1 so that
Film valve 1 is opened, and gap is formed between film valve 1, and liquid flows through from the gap.
Film valve 1 is connected with corresponding film valve seat 3 by a connecting portion, and tensioned groove 4 or elastic pleat are set on connecting portion
Wrinkle, tension force groove 4 divide for spill tension force groove and convex tension force groove, in pressure of the film valve by the liquid of forward flow, tension force groove
Or elastic deformation occurs for elastic folds, deflection is provided with the folding to film valve, to cause film valve can be with folding.
Traditional check valve, its deformed region must occur on film valve when its film valve is opened, and this just determines film valve not
Hard material can be used, so traditional check valve is doomed to use on high voltage control pump, and due to setting in the present invention
Flexible Reset structure as tension force groove, so film valve can use hard material completely, to ensure that the check valve can be in height
Normal work in hydraulic fluid flow medium.
When film valve 1 is two, the lip 2 extended to fluid flow direction is provided with the top margin of two film valves 1, when
When film valve 1 is three or more than three, the lip 2 extended to fluid flow direction is provided with the side of all film valves 1,
That is the positive direction that lip 2 flows along liquid extends, the lip on the top margin to lean of film valve or side offsets, lip knot
Structure advantageously reduces to be occurred anti-because of the dislocation of the adjacent membranes valve caused by film valve stress deformation or film valve foozle etc.
Structure collapses caused by offseting unbalance stress to seepage or film valve, so as to avoid the disabler of check valve；The lip
Still further advantage, when being exactly liquid one-way flowing, not only it is possible to prevente effectively from ' sharp ' seamed edge is turbulent to the flow-disturbing of liquid
Generation, but also be provided with the induction of " steam bubble " this additional defects that avoids thus turbulent flow and may trigger.
As shown in Fig. 9, Figure 10, now industrial bionical valve high frequency response one-way flow, which opens and closes valve, includes ring plate in one
6 and an outer ring plate 7, outer ring plate 7 be nested with interior ring plate 6, the gap between outer ring plate 7 and interior ring plate 6 is for fluid circulation
Combination forms circumferentially extending domes between each other for passage, interior ring plate 6 and outer ring plate 7, the tops of domes towards with
Fluid flow direction is consistent.
Described interior ring plate 6 is fixed in one in retainer ring 601, and with interior retainer ring 601 by one bullet can occur for interior ring plate 6
The connecting portion of property deformation is connected；Described outer ring plate 7 is fixed in an outer retainer ring 701, outer ring plate 7 and outer retainer ring 701
Elastically-deformable connecting portion can occur by one to be connected；Tensioned groove or elastic folds are set on connecting portion, in the interior He of ring plate 6
Outer ring plate 7 by the liquid of forward flow pressure when, elastic deformation occurs for tension force groove or elastic folds, with internal ring plate and outer
The relative folding of ring plate provides deflection, to allow inner ring piece and outer ring plate with respect to folding.
A support rib is provided with interior ring plate 6 and the circumferentially extending domes that combination is formed between each other of outer ring plate 7
Frame 5, support frame 5 are circumferentially extending domes, and support frame 5 can be used for supporting interior ring plate 6 and outer ring plate 7, can be with
Prevent the internal ring plate 6 of liquid of reverse flow and the back of outer ring plate 7 from applying pressure and make it that interior ring plate 6 and outer ring plate 7 deform,
The reverse direction flow anti-pressure ability of interior ring plate 6 and outer ring plate 7 is thereby may be ensured that, is covered with through hole 501 on support frame 5, liquid can be with
Flow through through hole 501.
As shown in Figure 11~Figure 14, when film valve is opened, the wedge angle of film valve is separated from each other, and liquid is between the wedge angle of film valve
Flow through in gap.
As shown in Figure 15, when film valve is opened, film valve is transformed into open position, in the process, tension force by closing position
Elastic deformation occurs for groove, and film valve rotates, and the wedge angle of film valve arcuately move by track, the keying of liquid flow direction and film valve
Direction is a kind of almost vertical relation, it is smaller so to allow for liquid buffer brake suffered when film valve is opened so that film valve
It is easier to open and close so that one-way flow keying response valve frequency of the invention is higher, and the wedge angle knot of three leaf film valves
Structure, more conducively flap cut liquid, so three leaf film valves are just provided with the keying characteristic of higher frequency response with respect to two leaf film valves.
Signified high frequency response one-way flow of the invention opens and closes valve and refers to that one-way flow opens and closes the response frequency of valve more than 50
Hertz.
Unidirectional keying valve industrial at present, it is one that mostly it, which opens and closes the flow direction for the liquid that direction is controlled with it,
Cause, see Figure 16, when liquid flows upwards, ball valve moves up, and when downward liquid flow, ball valve moves down,
As shown in Figure 16, if valve ball by：Elastic force-kx, damping forceExternal periodic force (driving force) is herein
The momentum surge d (m of liquid0υ)/dt, wherein d (m0Velocity component in υ)/dt formulas refers to flow rate of liquid from υ1To υ2's
Variable quantity, i.e. d υ=υ2-υ1, so because fluid density is constant, then to the liquid quality m of spheroid effect0It is constant, so d (m0
υ)/dt conversion can obtain d (m0υ)/dt=m0×d(υ2-υ1)/dt=m0×(dυ2/dt-dυ1/ dt), for the appearance that exocoel is infinitely great
Product is considered as d υ2/ dt=0, then in above formula common one runner of multiplication and division sectional area S and depth l, then can obtainSo valve ball stress is：
ρ is fluid density in formula, and v is runner volume.
Make d υ1/ dt=A0Cos (ω t), then (1) formula be changed into：ρvA0Cos (ω t)=Acos (ω t), if valve ball quality
For m, then stress balance equation is established by figure：
Mx "+γ x '+kx=Acos (ω t) ... ... ... ... ... (2)
Order
∵ β ＜ ω0Underdamping state, its general solution are：
X (t)=x0(t)+x1(t)=A0e-βtcos(ω′t+α)+A1cos(at+φ)…………………(3)
Wherein
(3) it is relevant with amplitude in formulaWith A1In, Section 1 is time attenuation, when the bigger decay of valve mass m
Rate is also bigger；Section 2 is frequency decay amount, and as driving frequency ω, to get over high amplitude smaller.φ is valve ball in other tg φ
Angle of lag, due to working as ω>ω0When valve ball direction of vibration will tend to the mode of vibration in opposite direction with liquid vibration, so
Valve ball will be unable to normal work, so the unidirectional valve working range that opens and closes of industry is typically in ω ＜ ω0In region, it is desirable to damping system
Number γ is sufficiently small, it is ensured that the angle of lag φ of valve ball is small, to ensure its unidirectional high frequency fast response characteristic for opening and closing valve.
By upper analysis, should be required for quick-acting valve：1. the quality m for opening and closing body should be small, or k, m ratio should it is high (but
The Opening pressure of so valve just increases, and this opens with low pressure valve and forms paradox, and this is that tradition keying valve is most fatal
The defects of)；2. the structure design of quick-acting valve and the type of flow of liquid should make damped coefficient γ sufficiently small (but in flowing side
Upward γ values be it is maximum, this be due to γ often direct ratio withThe quick closedown of valve is thus hindered, this is to pass again
System opens and closes the defects of valve key).
So borrow under the brief qualitatively comparative analyses of (2) formula mx "+γ x '+kx=Acos (ω t), this patent membrane flap type
Open and close the fast-response of valve.When tradition opens and closes valve and opened first, flow rate of liquid is from υ1It is changed into υ2, direction becomes there occurs obvious
Change, and almost to liquid flow direction any change does not occur for the unlatching that membrane flap type opens and closes valve its valve, so tradition opens and closes the mx " of valve
Value than instantly open and close valve mx " be worth it is much bigger, thus can be equivalent think：Participate in the equivalent mobile valve body to liquid effects
Quality, more small more than traditional m values of the m values of its membrane flap type；Second point, liquid flowing open and close the damping system of valve to membrane flap type
Number γ, more much smaller than traditional damped coefficient γ, this is due toIt is minimum in the component of its normal direction.2 points are enough based on more than
Bright membrane flap type, which opens and closes valve, has very high fast frequency response characteristic.
And by upper analysis, traditional keying valve is a kind of " plug flow valve ", and it is a kind of " dam that membrane flap type, which opens and closes valve,
Valve ", and therefore deduce that a more universal control effect, " damming " than " plug flow " control response speed faster.
Only just the present invention is made that explanation using preferable example above, but is not to be construed as the limit to claim
System, structure of the invention can have other changes, be not limited to said structure.In a word, all independent claims in the present invention
Protection domain in the various change made it is within the scope of the present invention.
