Below in conjunction with accompanying drawing the automatically operated valve of adjusting current of the present invention and water tap that this valve is housed are elaborated.
First embodiment:
Fig. 1 expresses the automatically operated valve of the adjusting current of single valve body structure.Label 10 expression box-shaped shells, housing 10 has the L shaped sleeve 11 of both ends open on the one sidewall.L shaped sleeve 11 is inner to be constituted one and L shapedly goes into circulation road 12, and going into circulation road 12 has an inner opening 12b who is connected with barrier film operating cavity 14.
The L jacket tube 15 that both ends open is arranged on housing 10 another sidewalls.It is symmetrical that these sleeve 15 phase counter septums 16 are close to above-mentioned L shaped sleeve 11.In L shaped sleeve 15, form circulation road 17.Passage 17 has opening 17a that is communicated with subsidiary conduit 18 and the inner opening 17b that is communicated with barrier film operating cavity 14.
On the inner opening part of L shaped sleeve 15, form valve seat 19.The valve body 20 that barrier film constitutes can contact with the inner opening 17b that closes out circulation road 17 with valve seat 19 and can also remove from the inner opening 17b of passage 17.
Valve body 20 has one to make bullport 10a that passage 17 is communicated with operating cavity 14 and one make operating cavity 14 and go into the overflow hole 10b that circulation road 12 is communicated with.
On part, fix a piezoelectric actuator A adjacent to the housing 10 of operating cavity 14.
As shown in Figure 1, piezoelectric actuator A comprises a cylindrical shape actuator casing C, and this housing has antetheca a and rear wall b, but is provided with plug d and three piezoelectric element e coaxially in actuator casing C, f, g axially reciprocating.These piezoelectric elements are around the coaxial setting of excircle of plug d.
In said structure, the top that plug d has telescopically to contact with the ear end face of valve body 20.Three piezoelectric element e, f, g constitutes piezoelectric element B.These piezoelectric elements are made by this way; They shrink when pulsed voltage is provided.
Therefore, when pulsed voltage was provided, a pair of clamping piezoelectric element e, f shrink to clamp plug d, and when not providing voltage, and the clamping of plug is released.
When not providing voltage, stroke piezoelectric element g is in extended configuration along plug, and when voltage was provided, piezoelectric element g shrank and also shortens whole axial length.
To each piezoelectric element e, f, g provide the order of voltage, just can make plug d in the axial direction to-and-fro motion by control, will describe in detail below this point.
As depicted in figs. 1 and 2, make and clamp piezoelectric element e with Bond a plurality of coaxial thin cover shape piezo-electric sheets that bond by coaxial assembling or around the plug d, f, at clamping piezoelectric element e, among the f, each piezo-electric sheet side and outside within it has electrode.
According to this structure, when pulsed voltage being provided for each piezo-electric sheet, this piezo-electric sheet radial contraction and the piezoelectric element e that is made up of these piezo-electric sheets, f also radially shrink to receive at last and just clamp plug d.
As shown in figs. 1 and 3, make stroke piezoelectric element g by coaxial assembling or around the plug with Bond a plurality of coaxial thin ring piezoelectric sheets that bond, in this element g, each piezo-electric sheet within it, have electrode on the excircle.
According to this structure, when providing pulsed voltage to piezo-electric sheet, the piezoelectric element g that piezo-electric sheet is formed along the plug axial shrinkage and by these piezo-electric sheets is axial shrinkage also.
Piezo-electric sheet is piezoelectric constant preferably.This piezoelectric constant is by ABO
3The ferroelectrics of perovskite type crystal structure (strong dielectric), as PZT[Pb(Zr, Ti) O
3], PLZT[Pb, La(Zr, Ti) O
3] and three kinds of compositions system of other fundamental composition PZT form.
In Fig. 1, label h represents elastic element, and as the circular cone cup spring, it is used for bias voltage ground piezoelectric element e, and f, g are pressed to antetheca a so that make piezoelectric element e, f, and g forms a whole assembly.
Though this piezoelectric element e, f, g has ring, and they also can be with the rectangle formation or by a plurality of fan-shaped composition the shown in Figure 4 and 5.
In Fig. 1, label 21,22 expressions have the Sealing of U-shaped cross section or y-shaped cross-section.The sealing part is used for improving the sealing of piezoelectric actuator to water.
Because plug d is often by piezoelectric element e, f, g clamps also and is subjected to very galling, so plug preferably is made of such bar; This bar has low coefficient of linear expansion, high hardness, high elastic modulus, high anti-deformation, high wear resistance and good processing properties.The bar that pottery is made can be used as plug d.
In Fig. 6, represented to be used for controlling the control gear C of actuator A operation.Control gear C comprises a microprocessor r, input interface s, output interface t and storage u.Store in the storage and be used for driving piezoelectric element e, the program of f and stroke piezoelectric element g of clamping.Actuator operated push-button switch v is connected to input interface s and piezoelectric actuator A is connected to output interface t through drive circuit DC.
By the piezoelectric element e of drive circuit DC with drive pressure electric actuator A, f, the voltage of g supplies to piezoelectric element e, f, g from power source PS.
Regulate the operational circumstances of the automatically operated valve of current below in conjunction with accompanying drawing 7 to 10 explanations.
When the operator presses the actuator control knob switch v(Fig. 6 that is contained on the control panel W) time, output signal passes to control gear C.Along with this output signal.Control gear D accesses to be used for driving from storage u and clamps piezoelectric element e, and the program of f and stroke piezoelectric element g is also pressed said procedure and given piezoelectric element e by drive circuit DC, f, and g provides pulsed voltage.
As shown in Figure 7, in the phase I, pulsed voltage does not also offer and clamps piezoelectric element f, and plug d keeps clamped state like this.And pulsed voltage offers and clamps piezoelectric element e and loosen to cause this element e to shrink and plug is become by clamped condition.
Sequentially, as shown in Figure 8, pulsed voltage offers stroke piezoelectric element g and shrinks one section distance corresponding to the pulsed voltage size that gives element g to cause this element g, and also moves a segment distance in the same direction by the plug d that clamps piezoelectric element f clamping as element g.
Then, as shown in Figure 9, pulsed voltage offers clamping piezoelectric element f makes piezoelectric element f shrink the clamping force of removing plug d, and the pulsed voltage that offers stroke piezoelectric element g stops so that element g is extended along the direction of arrow.
Figure 10 represents that f, g provide the mode of voltage to each piezoelectric element e.
The aforesaid operations process can repeat automatically so that plug d as worm with the order of magnitude of μ m/ stroke forward or towards the rear to moving.Therefore, the aperture of valve body 20 or opening angle can trickle adjustment so that current can accurately be regulated.
In the aforesaid operations process, because the motion of valve body 20 is clamping and the stroke piezoelectric element e that are made up of a plurality of piezo-electric sheets by giving, it is so little that f, g provide amount of movement that pulsed voltage realizes and each pulse plug.So the aperture or the opening angle mobile, valve of valve body 20 can tricklely be adjusted, flow also can fine adjustments like this.
As mentioned above, the automatically operated valve of adjusting current with this embodiment of single valve body structure has following advantage.
1. because by piezoelectric actuator A mobile valve 20, so valve body 20 can move forward or backward corresponding to the order of magnitude of pulsed voltage size with μ m/ stroke, valve can fine be regulated current like this.
2. because pass through piezoelectric actuator A mobile valve 20 fine, so just there is no need by the requisite retarder of common valve of handling motor operation, this valve becomes compact like this.
3. because valve body 20 is made by barrier film, so promoting valve body 20 necessary driving forces, mobile plug d can reduce to minimum, ten minutes power saving like this.
4. because valve body 20 moves by piezoelectric actuator A straight line, so just there is no need by indispensable the rotatablely moving of common valve-straight-line switching mechanism of handling Electric Machine Control, this makes this valve become compacter.
Figure 11 and 12 expressions have the automatically operated valve of the adjusting current of double body structure.
Go into circulation road 63,64 respectively as the cold water channel and the hot water channel of the mixing valve of the water that is used for obtaining required water temperature.Go into circulation road 63,64 the opening 63a that is communicated with respectively with cold feed pipe 55 and hot water service pipe 66,64a are arranged.Go into circulation road 63,64 inner opening 63b, 64b are arranged.This two opening is connected with the operating cavity 67,68 that forms on the end of housing respectively.
The T-socket 69 that both ends open is arranged on another sidewall of housing.Sleeve 69 forms circulation road 70 within it.Go out the passage that circulation road 70 is used as the mixing water in the mixing valve.
Go out circulation road 70 opening 70a that is communicated with mixed conduit 71 and opening 70b, the 70c that is connected with operating cavity 67,68 are arranged.
On the open part of the interior bifurcated of T-socket 69, form a pair of valve seat 72,73.The a pair of valve body of being made by barrier film 74,75 can contact so that close opening 70b, 70c with valve seat 72,73.This can also shrink valve body and break away from valve seat 72,73 to open out opening 70b, the 70c of circulation road 70.
Fix a pair of piezoelectric actuator A-1, A-1 respectively at the two ends of housing 60.
As shown in figure 11, the structure of piezoelectric actuator A-1 and piezoelectric actuator A shown in Figure 1 are basic identical.
Figure 13 represents to be used to control the control gear C-1 of piezoelectric actuator A-1, A-1.Except that following array structure, the structure of the control gear C of the piezoelectric actuator A of the structure of control gear C-1 and the valve that is used to control single valve body shown in Figure 1 is basic identical.
Except that actuator control knob switch V, Temperature Detector 80 is connected to input interface S.And being used as the actuator A-1 that regulates cold and hot current respectively, A-1 is connected to output interface t.
The autocontrol valve of operating above-mentioned adjusting current below in conjunction with flowchart text shown in Figure 13 is with the method for the mixing water that obtains required water temperature.
In the phase I of operation, set up the predetermined temperature required value Ts(1001 of button) by the temperature on the operation control panel W.
Control gear carries out proportion integration differentiation (PID) control (1003) and control signal is sent to the piezoelectric actuator A-1 that is respectively applied for the cold and hot current of adjusting, the drive unit of A-1 according to the difference △ t between temperature T s and Tm.
Therefore, valve body 74,75 can be opened or closed respectively, and with required mixed proportion mixing hot and cold current.
In the aforesaid operations process, because by piezoelectric actuator A-1, A-1 control valve body 74,75, pulsed voltage offers piezoelectric element e, f, g in proper order by the illustrated mode of operation of Fig. 7 to 8.Like this, the mixed proportion of hot and cold water can accurately be adjusted so that obtain the mixing water of required water temperature.
In the above-described embodiments, be that mixing valve as mixing hot and cold water describes though regulate the automatically operated valve of current,, the automatically operated valve of these adjustings current also can be used for other technical field, as being used as the water (flow) direction control valve.This water (flow) direction control valve is used for a plurality ofly going out circulation road current being changed to another direction from a direction through what housing one end single went into the circulation road and the housing the other end.
As mentioned above, the automatically operated valve with adjusting current of double body structure has following advantage:
1. owing to utilizing piezoelectric actuator A-1, A-1 mobile valve 74,75, so valve body 74,75 can be mobile forward or backward with the order of magnitude of μ m/ stroke corresponding to the size of the pulsed voltage that offers piezoelectric element g.
2. owing to utilizing piezoelectric actuator A-1, A-1 to make valve body 74,75 fine motions, just dispensable by the necessary speed reducer of common valve of handling Electric Machine Control like this, make this valve compactness thus.
3. because valve body 74,75 is made of barrier film, mobile plug can be reduced to minimum to promote valve body 74,75 necessary driving forces, saves electric power thus significantly.
4. since valve body 74,75 move point-blank by piezoelectric actuator A, so just do not need not provide conventional valve essential by rotatablely moving-straight-line switching mechanism that motor is handled, thereby make this valve arrangement compactness.
Several preferred remodeling of automatically operated valve of the above-mentioned adjusting current of 15 to 21 explanations with reference to the accompanying drawings below.
Remodeling 1:
As shown in figure 15, the embodiment with valve shown in Figure 10 is identical basically to regulate the structure of automatically operated valve of current in remodeling being used in 1, and just the structure of piezoelectric actuator is slightly different.
That is, in Figure 15, label K represents a spring storage chamber, and this chamber is arranged on the outer surface of the rear wall b of actuator casing C.In the K of chamber, be provided with a pair of spring supporting plate l, m, a pressure spring P is contained between two spring supporting plate l, the m.
Spring supporting plate l is connected with plug d is whole, and spring supporting plate m links to each other with thread spindle O, and this thread spindle is screwed among the supplemental wall n that is attached on the rear wall b.
Because this structure, when plug d was in relaxation state, plug d was moved to a waiting position, as is in foremost position, so that utilize the biasing force of pressure spring P that valve cuts out fully.
The biasing force of pressure spring P can easily be adjusted by changing the distance between spring supporting plate l.m.And the change of above-mentioned distance realizes by turn thread spindle O.
The control gear C-1 that is shown in the operation that is used for control valve of Figure 13 can be used for the valve of this remodeling equally.
But, piezoelectric element e, the f of this remodeling be with embodiment illustrated in fig. 11 in the antipodal mode of piezoelectric element e, f activate.
That is, when no pulse voltage is supplied with, clamp piezoelectric element e, f and shrink, therefore can not provide clamping force to plug; And when supplying with pulsed voltage, clamp piezoelectric element e, f expansion, thereby clamp plug d.
Therefore, when not having pulsed voltage to offer any clamping piezoelectric element e, f, the clamping force that imposes on plug d is just removed fully, therefore shifts plug d onto foremost position by means of the biasing force of pressure spring P, thereby valve cuts out fully.
The operational circumstances that adopts the valve of this remodeling to obtain temperature required mixing water below in conjunction with 15 pairs in accompanying drawing describes.
Valve as shown in figure 13 is such, temperature value Tm is input among the control gear C-1, and control gear C-1 carries out PID control and operation signal is sent to the piezoelectric actuator A-2 that is used to regulate hot and cold current, the driver of A-2 respectively according to the temperature difference △ t of temperature T s and Tm.
Therefore, valve body 74,75 opens or closes independently of each other, and hot and cold current are mixed with required proportions of ingredients.
In aforesaid operations, because valve body 74,75 is handled by piezoelectric actuator A-2, A-2, and according to providing pulsed voltage to piezoelectric element e, f in order in conjunction with the operating procedure that Fig. 7-Fig. 9 set forth, therefore just can trickle and accurately regulate hot water or cold water's proportions of ingredients, thereby obtain temperature required mixing water.
In addition, even when the electric power accidental interruption, plug d also can be released and move to foremost position so that with the valve complete closed under the partial pressure of pressure spring P, thereby has prevented owing to water continuously outflows the waste that causes.
Figure 16 shows a kind of improved form of this remodeling embodiment's automatically operated valve, and wherein piezoelectric actuator A-3, A-3 structurally improve.
In Figure 16, piezoelectric element e, the f, the g that constitute the major component of piezoelectric actuator A-3, A-3 are installed among the actuator casing C, stroke piezoelectric element g has a core, and this part is connected on the inwall of housing C by a bearing support H and a pair of supporting arm H-1, H-1.
The approach end of supporting arm H-1, H-1 links to each other with the two ends of stroke piezoelectric element g, has the approach end on the end that is connected to supporting arm H-1, H-1 and clamp piezoelectric element e, f.
In Figure 16, label q represents to be arranged on the brake shoe between the outer surface of supporting arm H-1, H-1 end and plug d, and this brake shoe q has sufficient friction and abrasion strength, so that clamping plug d to piezoelectric element e, when f provides pulsed voltage.
Because this structure makes this improved form compare with valve shown in Figure 15 and has following attendant advantages:
1. owing to piezoelectric element e, f, g are installed among the actuator casing C by bearing support H and supporting arm H-1, H-1, so prevented the direct contact between piezoelectric element and the housing C, therefore, piezoelectric element e, f, g can be out of shape fully, thereby have increased clamping piezoelectric element e, the clamping force of f generation and the move distance of stroke piezoelectric element g greatly.In addition, owing to the clamping force and the stroke power that are applied directly on the actuator casing C have been eliminated.So housing C can use gossamery made, thereby make the compact structure, in light weight of piezoelectric actuator A-3, A-3.
2. in this improved form, stroke piezoelectric element g and clamp piezoelectric element e, f and make by with Bond the piezo-electric sheet of a plurality of concentric circle annulars being bondd around plug d wherein has electrode on the inside and outside periphery of each piezo-electric sheet.Therefore, the operation that can easily bond, thus cause the manufacture cost of piezoelectric actuator A-3, A-3 to descend.In addition, also prevented coming off of piezo-electric sheet.
Clamping piezoelectric element e, f shown in Figure 2 produce circumference stress between piezo-electric sheet, this makes the adhesion strength of Bond descend and the piezo-electric sheet obscission takes place.
Remodeling 2:
As shown in figure 17, structure and the embodiment's shown in Figure 11 valve that being used to of this remodeling 2 regulated the automatically operated valve of current is identical basically, and just the structure of piezoelectric actuator A-4, A-4 is slightly different.
That is, in this remodeling, plug d is made into a hollow cylindrical part, and is provided with a core head 82 by spring P-1 bias voltage.
More particularly, the cylindrical shape plug is to be arranged on coaxially among the cylindrical shape actuator casing C that its two ends have antetheca a and rear wall b respectively, and can be in the axially to-and-fro motion of housing C platform.
The front end of plug d has a ring end wall 81, and a central opening 83 is arranged on it, and core head 82 passes from this opening.
Be provided with spring P-1 in plug d, the two ends of spring P-1 are supported by the major diameter part 82b of core head 82 and the rear wall b of actuator casing C respectively.
Because this structure, core head 82 all the time by spring P-1 towards the place ahead bias voltage, and force the major diameter part 82b on it to contact with the ring end wall 81 of plug d.
Set forth the mode of operation of the plug d with said structure below.When plug d was forwards mobile, the core head 82 that is biased into by spring P-1 on the ring end wall 81 of plug d also moved forward identical distance.
On the other hand, when plug d retreated, the ring end wall 81 of plug d contacted with the major diameter part 82b of core head 82, thereby core head 82 and plug d are retreated together.
In addition, when the pulsed voltage accidental interruption that provides to piezoelectric element e, f, g (for example outage), clamping force disappears, owing to the effect of the biasing force of spring P-1, P-1 makes plug d and core head 82 move forward together.
Therefore, valve body 74,75 contacts with valve seat 72,73, thereby then valve has cut off hot and cold current fully and prevented owing to water continuously outflows the waste that causes.
In addition, together move forward to along with the plug d that orders about by piezoelectric element with after valve 74,75 contacts at core head 82,82, even plug d travels forward again, valve body 74,75 also only bears the biasing force of spring P-1, P-1, this power is much smaller than the actuation force that is produced by stroke piezoelectric element g, therefore, just can prevent of the infringement of this impact force effectively to valve body 74,75.
Remodeling 3:
As shown in figure 18, this remodeling is characterised in that: the control gear C-2 that controls a pair of piezoelectric actuator A-5, A-5 operation, be equipped with one and be used to detect the circuit POD of powering-off state of electric power that supply company is received the drive circuit DS of piezoelectric actuator A-5, A-5, under the situation of outage, also can make piezoelectric actuator A-5, A-5 activate reliably or operate even make.
The structure of control gear C-2 is identical with the control gear C-1 of the piezoelectric actuator A-1, the A-1 that are used to control binary valve shown in Figure 10 basically, just some difference on following structure.
Promptly, in control gear C-2, the circuit POD that is used to detect outage or opens circuit is inserted between the input interface S of power supply circuits 90 and microprocessor r, in addition, control gear C-2 has reserve battery BB(also can adopt spare capacitor), it is used for to control gear C-2 and drive circuit DS power supply, when from the power cut of power ps, circuit POD and battery BB begin to enable, and microprocessor r and drive circuit DS are remained in operation according to program, are fully closed until valve.
The flowsheet of explanatory drawing 18A in more detail below.When power cut (1010), circuit POD and battery BB enable (1011), make piezoelectric driving circuit DC running so that discharge the voltage (1102) that is fed to piezoelectric element e, f, g.Therefore, the clamping force of piezoelectric element e, f, g discharges (1013), thereby plug d for example closes valve (1014) and stops water outflow (1015) to the direction motion of cut-off valve under the effect of spring.
In this remodeling, clamp piezoelectric element e, f and be designed to when they just clamp plug d when they provide pulsed voltage.Foregoing circuit POD is also applicable to piezoelectric actuator A-5, A-5, and these two piezoelectric actuators all have clamping piezoelectric element e, f respectively, clamp piezoelectric element e, f and are designed to when they just do not clamp plug d when they provide pulsed voltage.
In Figure 19, a kind of piezoelectric actuator A-5 that has is disclosed, the automatically operated valve of the adjusting current that belong to remodeling 3 of A-5.The structure of this valve is identical with embodiment's shown in Figure 11 valve basically, and just the structure of piezoelectric actuator A-5, A-5 is slightly different.
That is, as shown in figure 19, each piezoelectric actuator A-5 has a manual plug advancement mechanism X, and shown in the figure is resilient manual plug forwarding button on a kind of core that is installed in rear wall b.
When pressing manual plug advancement mechanism X when press...withing one's finger, plug advancement mechanism X protrudes forward and contact with the ear end face of plug d, and then overcomes the clamping force that is applied on the plug d by clamping piezoelectric element e, f plug d is promoted forward.
Therefore, when making the valve shut-down operation that is in opening state, just can valve cut out fully by pushing manual plug advancement mechanism X owing to meet accident (as sudden power).
Below in conjunction with the mode of operation of operating process block diagram illustrations valve shown in Figure 20, when power cut (1020).Circuit POD enables (1021), makes piezoelectric driving circuit DC work so that discharge the voltage (1022) that supplies to piezoelectric element e, f, g.Therefore, piezoelectric element e, f, g are turned off and clamp piezoelectric element e, f and clamp plug d(1023).Then, valve cuts out fully (1024) (1025) by pushing manual plug advancement mechanism X.In aforesaid operations, circuit POD and drive circuit DC are also powered by reserve battery BB.
When to clamping piezoelectric element e, when f provides pulsed voltage, just plug can being installed among piezoelectric actuator A-5, the A-5.
Remodeling 4:
As shown in figure 19, this remodeling is characterised in that, there is a small diameter portion q-1 on the top of plug, makes the top end surface that bears hydraulic pressure on the plug d long-pending as far as possible little thus.
Because this structure, between the whole period of energization of piezoelectric actuator A-5, A-5, the impact force that is acted on the plug d by the water of being regulated can be reduced to minimum.That is, there is the impact force (water pressure) of adverse effect can be reduced to minimum, makes the motion of piezoelectric actuator can pass to plug d exactly, thereby can control accurately the motion of valve body 74,75 to the motion of plug d.
Remodeling 5:
This remodeling is characterised in that: added the operating mode that blocks water in the operation operating mode of remodeling 2 described valves.
That is, as shown in figure 21, the control gear C-3 that is applied to the valve of this remodeling 5 has block water an operating mode testing circuit SMD and the push switch 91 that discharges water.A hand detector 92 of surveying staff links to each other with the input interface S of control gear 3 with the push-button switch 93 that blocks water.
Because this structure, when pushing when discharging water push-button switch 91, control gear C-3 allows power supply or drive circuit to piezoelectric actuator A-6, A-6 transmits pulsed voltage, so that valve is opened, as long as maintained switch 91 is in pressed state always, just constantly provide pulsed voltage to piezoelectric actuator A-6, A-6; And when switch 91 resets disconnection, just stop to supply with pulsed voltage to piezoelectric actuator.
Therefore, be in time of on positi, just can regulate waterdrainage amount by the setting push-button switch 91 that discharges water.
Simultaneously, survey when in one's hands, will emit the water of prearranging quatity when the hand detector.
On the other hand, after pressing cock of water drain 91 and making it to connect, when hand detector 92 adversarys' detection finishes or scheduled time when covering, the operating mode testing circuit SMD that blocks water among the control gear C-3 just detects the operating mode and allow control gear C-3 send signal of blocking water, so that discharge the voltage that offers piezoelectric element e, f, g respectively.Therefore, the clamping force that is applied on the plug d is disengaged, thereby plug d just automatically moves forward under the effect of the biasing force of spring P-1 valve cuts out.
As mentioned above, in this remodeling, because the operation of cut-off valve is undertaken by spring P-1, so determine with the position that water cuts off fully it is irrelevant with the serviceability of control gear C-3, if therefore the sequence of operation of valve is to carry out layout with the above-mentioned position that blocks water as initial state, plug d just can calibrate at each operating position that blocks water fully corresponding to the operating position of the number of drive pulses of control gear C-3 counting so.
Therefore, after the operation that blocks water, the motion of plug d just can have been controlled by control gear C-3 again exactly.
That is to say, after the calibration or the operation that blocks water, when with the pulsed voltage (it is relevant with the pass degree of valve) of required ordinal number when supplying to piezoelectric element e, f, g, valve body 20 just can be easily and accurately is moved to a predetermined valve position of opening, thereby the temperature of mixing water is controlled.
According to this remodeling, valve body 20 is all the time by towards the position bias voltage that blocks water, and when clamping force was removed, valve body 20 just moved forward until closing valve seat 19 fully.
Therefore this remodeling has following advantage:
1. piezoelectric actuator is like this design and control: when drive unit not when actuator provides driving voltage, clamping force on the plug d or valve body 20 are released, therefore, can voltage be provided and valve cuts out to piezoelectric actuator by stopping with the location independent ground of valve body and barrier film.
The elasticity or the biasing force that 2. can not surpass spring P-1 owing to the power on the valve seat 72,73 that is applied to valve body 74,75, thereby avoided effectively on valve body 74,75 and valve seat 72,73 or barrier film, applying excessive power or stress, and then can prevent these parts damages.
3. because the position that blocks water fully is mechanically to be determined by the biasing force of spring P-1, therefore just do not need to be provided with a kind of detector that valve body arrives the position that blocks water fully that detects, the control program of valve also has been simplified simultaneously.
4. because to stop the position that blocks water of current fully be mechanically to be determined by the biasing force of spring P-1, so the position that blocks water fully can be configured to initial position, and the position of the valve body that is calculated by control gear C-3 can be at each position correction that blocks water.Therefore, the positional error that is accumulated between the period of energization of piezoelectric element e, f, g can be calibrated or eliminate, so just the position of control valve body exactly.
Second embodiment:
Present embodiment relates to is a kind of water tap F that is used to regulate the automatically operated valve of current at the sort of described in first embodiment that is equipped with.

Can easily understand from Figure 23, the part 120b that discharges water of the inclination of cock body 120 is separated by dividing plate 140, goes out circulation road 124 and a watertight (waterproof) cavity N to constitute one, and control gear C-4 just is contained in the middle part of cavity N.
That is, in watertight cavity N, control gear C-4 and the control panel E, the G fix in position that are used for transmitting control signal to control gear C-4.
By this way, according to present embodiment, because mixing valve M and control gear C-4 are contained in to overall compact in the cock body 120, can be reduced to minimum so be used to install the requisite space of water tap F, and the space of room (as the toilet) can be effectively utilized, and the required electric wire that is used to handle water tap F is simultaneously also laid easily.
In addition, because mixing valve M is the lower end that is contained in cock body 120, so improved the stability of water tap F.
In addition, because hot water or cold water's mixing is to carry out in the lower end of cock body 120, therefore between mixing valve M and dewatering outlet 123, just can limit one and sufficiently longly go out circulation road 124, cold like this, hot water can fully mix in going out circulation road 124, thereby emits temperature required water.
Although mixing valve M, control gear C-4 and control panel E, G can have any suitable structure according to installation site and other condition of water tap F, in this embodiment, they have following preferred structure.
