Technical field

The present invention relates to a kind of control valve unit, it has: by multiple along orientation be arranged side by side can the valve group that forms of electrically-energized valve cell, these valve cells all have the first valve interface of valve control signal for receiving electricity, and these valve control signals can cause and on one's own initiative valve cell switched to first switching position; A linkage unit, for receiving the control signal of the electricity to the outside that the manipulation of valve cell controls; The first two linkage units, it be electrically connected with a linkage unit by first internal connecting wire of control valve unit on the one hand, and another aspect is connected with the first valve interface by the first manipulation cable of the connected electricity for transmitting valve control signal.

Background technique

The valve cell of multiple multi-way valve form is contained by the control valve unit that EP 1 094 260 B1 is known, these valve cells are assembled into valve group by being mutually arranged side by side, and all there is the first valve interface of lateral arrangement, can the valve control signal of feed-in electricity by valve interface, relevant valve cell is switched to first switching position on one's own initiative.Described valve cell the chances are monostable valve cell, it automatically switches again after removing valve control signal gets back to initial position.These valve cells obtain its valve control signal by multiple manipulation cable, and these are handled cable and are all connected with the secondary linkage unit being configured in control valve unit side by the plug of oneself.The contact of secondary linkage unit is connected with a linkage unit with multi-pole type plug-in device by the connection wire of structure inside on a printed circuit board, this linkage unit can be connected with central plug, transported the control signal of the electricity from external control device by this central plug, these control signals are corresponding to the valve control signal being passed to valve interface.

Under many circumstances, in order to control load, use valve cell, these valve cells can switch to first or second switch position on one's own initiative.This valve cell is so-called bistable valve or sentinel valve.In order to the valve control signal of feed-in electricity, this valve cell has two valve interfaces, and these valve interfaces are all supplied by handling cable with required valve control signal.EP 0 796 519 B1 discloses an example of the control valve unit being equipped with bistable valve cell.

In the control valve unit being equipped with at least one bistable valve cell, very general problem is, cable joining may be mistaken.When not noting, may inadvertently be connected on the second valve interface by being arranged for the manipulation cable be connected with the first valve interface, cause control valve unit correctly not work, even can cause the consequence of damage in the most severe case due to control load mistakenly.

Summary of the invention

The object of the invention is to, propose the control valve unit of type described in a kind of the beginning part, wherein equipping in bistable valve cell situation at least in part, the risk of the electrical connection producing mistake can be reduced significantly.

In order to realize described object, specify for the control valve unit of type described in the beginning part: at least one valve cell has the second additional valve interface of the valve control signal for receiving electricity, and these valve control signals can cause the second switch position being switched on one's own initiative by valve cell and be different from first switching position; Be provided with the second two linkage units, it is electrically connected with a linkage unit by the connection wire of the second inside of control valve unit on the one hand, handle cable by second of the connected electricity for transmitting valve control signal to be on the other hand connected with at least one second valve interface, wherein whole first handle cable and all pass through the first common cable linkage unit and be connected with the first two linkage units, and whole second manipulation cable all passes through the second common cable linkage unit is connected with the second two linkage units.

In this control valve unit, one, multiple or whole valve cell is all equipped with two independent valve interfaces, these valve interfaces can realize feed-in valve control signal, make each related valves unit can switch to first switching position or second switch position on one's own initiative.This valve cell can be the valve cell of bistable especially, and it can keep the corresponding switching position, until switch to another switching position on one's own initiative.However valve design unit, the danger mistaken when the cable setting up electricity connects is but very little, because on the one hand, for connecting the first valve interface first handles cable, on the other hand, for connecting at least the second valve interface second handles cable, all draw from special (zugeordnet), the common secondary linkage unit that arrange, thus understand be, cable can be handled drawing from first of the first two linkage units and be connected with the first valve interface, and the second manipulation cable drawn from the second two linkage units can be connected with the second valve interface.Thus obtain a kind of reliable and clear cable corresponding relation, and high running cost can not be involved.

Favourable improvement of the present invention can be obtained by dependent claims.

The optimal way of the first and second valve interface arrangement on valve cell is that all first valve interfaces are all arranged in the region of the first longitudinal side of valve group, and all second valve interfaces are all arranged in the region of second longitudinal side opposed with the first longitudinal side of valve group.The manipulation cable extending two longitudinal side of valve group the laying handling cable can be simplified in this way widely, because can gather when needed without any problems.

The multi-way valve that valve cell is especially presetting, wherein each valve interface is can the constituent element of electrically-energized presetting valve.So only have the valve cell of a first valve interface to be preferably only configured to monostable valve cell together with a presetting valve, the valve cell of two valve interfaces is equipped with then to have two presetting valves, and preferably bistable type, it is usually also referred to as sentinel valve (Impulsventil).

Preferably be arranged in a join domain by two secondary linkage unit concentrated areas, this join domain is arranged in the region before valve group in the orientation of valve cell.Just become from here and be very simply, first and second handle cable in the mode understood, one is stretched left, another stretches to the right, namely the mutually opposing longitudinal side towards valve group stretches, so that make these handle region that cables extend to the mutually opposing longitudinal side of two of valve group, here, there is the first valve interface on the one hand, have the second valve interface on the other hand.

Being also advantageous in that of this cable laying mode, handle cable and need not cross valve group, also need not pass between adjacent valve cell, this can make whole device on the whole closely.Valve cell can be arranged side by side without any problems, and the spacing making them mutual is very little, or even mutually reclines.

These valve cells can be arranged on the valve seat of such as tabular of control valve unit independently of each other.In addition also these valve cells can be assembled into the valve group of a self-supporting, but also valve group can be arranged on valve seat when needed.

Preferably also be arranged in the identical join domain before valve group by a linkage unit, two secondary linkage units are located in this join domain.Inner electrical connecting wire can be made in this way very short.In addition, the connection task of the central authorities likely needed all focuses in this join domain.

According to a kind of arrangement useful especially, two secondary linkage units are once between linkage unit and valve group.Keep thus being convenient to very much get at a linkage unit, to take connection measure to it.Two secondary linkage units can be arranged transverse to the side direction of direction side by side of valve cell with mutually staggering, thus they particularly all near the following longitudinal side of control valve unit, namely can have the first or second valve interface to be connected in addition in this longitudinal side.

Need to be set up with secondary linkage unit the plug unit that two cable linkage units being electrically connected preferably can be settled rapidly in connector process.Cable linkage unit can not can be disconnected to fix, but they preferably can be disconnected to settle, thus can change like a dream, if need to reequip for the quantity of the change of valve cell and/or form.

In order to be placed on valve interface by manipulation cable, best each manipulation cable is equipped with connector arrangement in one end opposed with cable linkage unit.Assemble the independent connector arrangement of oneself preferably to each manipulation cable here.Each connector arrangement can particularly removably be plugged on one of valve interface.

Another kind of favourable design proposal regulation, no matter whole first handle cable, or whole second handles cable, is all aggregated into the composite cable of the bar pencil of oneself.In this way, extend the first valve interface first handles cable, and extends the second manipulation cable of the second valve interface, all can understand very much as the cable unit gathered and can not lay with obscuring.

The mode being aggregated into composite cable is such as, is banded together (zusammenschn ü ren) by multiple manipulation cable respectively by so-called cable connector in multiple position spaced along the longitudinal.But according to a kind of favourable make, the usual cable cover(ing) be made up of plastic materials of the manipulation cable belonging to corresponding composite cable is interfixed.Particularly produce the fixing of a kind of material fit, wherein according to a kind of favourable scheme, all cable cover(ing)s are all assembled all-in-one-piece sheath body.Obtain a kind of bunch of cables be firmly held in together in this way, but such as also composite cable can be embodied as section cable.

In corresponding composite cable, each length handling cable can be divided into step, make them under laying state, extend different distances along valve group, cause they all valve interface as lower area in stop, namely can be equipped with suitable connector arrangement to them in this region.Owing to correspondingly taking the measure making these length handling cable mutually mate, therefore the connector arrangement that can realize in this way making to belong to same compound cable is one after the other arranged in a row, thus the connector arrangement that can be connected with the first valve interface and the connector arrangement that can be connected with the second valve interface can not be mistaken mutually.

In order to connect outside connection set, one time linkage unit such as has multi-pole type plug-in device, but also can have the field-bus interface that can realize serial signal transfer.

A linkage unit and two secondary linkage units can be especially be the constituent element of the connecting body of shell type structure, and connecting body inside is provided with inner connection wire.

In order to realize inner electrical connection between a linkage unit and secondary linkage unit, a linkage unit preferably has a contact of multiple electricity, and two secondary linkage units are equipped with multiple secondary contact, these secondary contacts all can connect the manipulation cable being suitable for transmitting valve control signal.Additionally, each linkage unit also can contain at least one earthed contact.

According to a kind of the first feasible design variant scheme, the secondary contact of two secondary linkage units only connects from different contact.In other words, thus each contact is only connected with a secondary contact.Particularly a lot of of valve group, particularly all a valve cell is equipped with during two valve interfaces this flexible program is favourable.If at least one valve cell only has a first valve interface, then one of contact also correspondingly keep need not.

By contrast, in the mode of execution that another kind is favourable, the contact utilizing existing quantity best can be realized, accordingly, an one or more contact is not only connected with the secondary contact of a secondary linkage unit, and is also connected with the secondary contact of another secondary linkage unit simultaneously.Therefore, if the second valve interface due to respective numbers do not exist cause one or more secondary contacts of the second two linkage units to keep need not, then can utilize the secondary contact be also connected with these no secondary contacts described of the first two linkage units, to connect the valve cell being only equipped with the respective numbers of a first valve interface.Thus the outfit degree by repeatedly utilizing contact can optimize control valve unit best.

Shown relatively it is advantageous that the first two linkage units can be the twice of the second two linkage units with the quantity handling the secondary contact that cable be connected.In this case, so the existing secondary contact of the half quantity of the first two linkage units is all connected with a this contact, this contact is also connected with the secondary contact of the second two linkage units simultaneously.

Preferably these valve cells 27 are separately fixed on valve seat 29.This such as realizes respectively by least one set screw 31.But before being installed on valve seat 29, also just multiple valve cell 27 can being assembled into (selbsttragend) valve group of a self-supporting, so this valve group can be installed as a unit, thus need not separately carrying out valve and fix.

Whole valve cell 27 is called valve group 32 together below.The longitudinal axis of valve group 32 overlaps with orientation 28.

Valve group 32 has the end face opposed with valve seat 29.It also have direction opposed, transverse to the first and second longitudinal side 33,34 of orientation 28.Two sides be in orientation 28 of valve group 32 define front 35 and in FIG towards the back side 36 of observer.

Each valve cell 27 has the valve member 37 of at least one inside, and described valve member can be positioned at least two switching position.According to each residing switching position, valve member 37 sets up different connections between the valve passage of inside.These valve passages pass to bottom surface 38, valve cell 27 in advance with this sole arrangement on mating face 30.

Valve seat 29 is run through by multiple valve base channel.Below these valve base channel, have at least one service duct 42 and at least one discharge route 43, in the present embodiment, the latter has two.At least one service duct 42 can be connected with unshowned external pressure source, and at least one discharge route 43 can be communicated with air.On the other hand, aforementioned channels repeatedly passes to mating face 30 respectively, causes them to be communicated with at least one valve passage of each valve cell 27.Can realize in this way jointly for valve cell 27 accommodating fluid and displacement fluids.The fluid pressure medium provided by pressure source especially pressurized air.

As other valve base channel, have multiple service aisle 44, these service aisles are separately communicated with an only valve cell 27.Each valve cell 27 is preferably connected with two this service aisles 44, and these two service aisles at one end also pass to mating face 30 for this reason.Other shown in Fig. 1,3 and 5 of service aisle 44 passes into the connection that region can realize fluid circuit, these fluid circuits extend load not shown further, such as extend fluid actuated drive unit, the working method of these drive units should be controlled by valve cell 27.

If lack valve seat 29, then also pressure source, air and load directly can be connected with the valve passage can't see by accompanying drawing of valve cell 27.

The make of valve cell 27 can make it be handled by electricity.They are such as presetting multi-way valve, and by there is the main valve 45 of valve member 37 and one or two can electrically-energized presetting valve 46a, 46b composition.At least one valve cell 27, both containing the first presetting valve 46a, again containing the second presetting valve 46b, wherein such as always has three this valve cells 27 being equipped with two presetting valve 46a, 46b.Additionally, at least one other valve cell 27 only can be equipped with unique (first) presetting valve 46a, and wherein this embodiment also always has three this valve cells 27.

Each presetting valve 46a, 46b can be activated by the valve control signal of electricity, wherein produce the regulated signal of fluid in active state, utilize this regulated signal valve member 37 to be switched to one of possible switching position of in the present embodiment two.

Therefore can by the electro activation of the first presetting valve 46a by valve member 37 or related valves unit 27 on one's own initiative (aktiv) switch to first switching position, when the presetting valve 46b of existence second, also switch to second switch position by its activation.

If valve cell 27 only contains unique (first) presetting valve 46a, then this valve cell preferably so-called monostable valve cell 27, when the first presetting valve 46a deexcitation, this valve cell based on existing fluid and/or the elastic mechanism of machinery automatically switch and get back to initial position.If valve cell 27 is equipped with two presetting valve 46a, 46b, the then valve cell of its especially bistable, even if wherein valve member 37 also remains on the switching position by handling residing for presetting valve 46a or 46b enduringly after relevant presetting valve deexcitation, until get back to another switching position by being switched by this valve member on one's own initiative the activation of another presetting valve 46b or 46a.

The make of valve cell 27 also can be different from the present embodiment, but can manipulate directly at least in part, here not containing presetting valve.In this case, the valve member 37 directly switching and arrange can be caused by electrically-energized drive unit.

As long as there is presetting valve 46a, 46b, just they are arranged in the side of valve cell 27, thus in the region of one of their two longitudinal side 33,34 being all in valve group 32.Preferably all first presetting valve 46a correspond to the first longitudinal side 33, and all second presetting valve 46b correspond to the second longitudinal side 34.

In order to the valve control signal of required electricity can be received, be equipped with the first valve interface 47a being suitable for this to each first presetting valve 46a, and be equipped with the second valve interface 47b of relative configurations to each second presetting valve 46b.Described interface be especially be designed to produce electricity that connector connects or the interface of electromechanics.

If valve cell 27 does not have presetting valve, then at least one valve interface 47a, 47b is positioned at another suitable position.Under any circumstance all advantageously, all first valve interface 47a are arranged in abreast in the region of the first longitudinal side 33 of valve group 32 in orientation 28, and all same region being arranged in the second longitudinal side 34 of valve group 32 in orientation 28 abreast of all second valve interface 47b.

Here, these valve interfaces are preferably following directed: towards the opposite towards with the second valve interface 47b making the first valve interface 47a.Here towards preferably perpendicular to the direction of orientation 28.All valve interface 47a, 47b are particularly perpendicular to midplane 48, and this midplane is such as formed perpendicular to the vertical axis 49 of mating face 30 by orientation 28 and valve group 32.

Valve cell 27 once (Prim r) linkage unit 52 from the edge (Bord) being arranged in control valve unit 100 obtains the valve control signal of its electricity, a cable linkage unit 54 particularly can be disconnected to be connected with this linkage unit, one time cable linkage unit is connected with the control cables 55 of at least one electricity, and this control cables extends the control gear of the electricity of outside not shown further.The control gear of the electricity of this outside provides the control signal of electricity to control valve unit 100, depending on the design of a linkage unit 52, and this control signal or directly formation valve control signal, or be converted to this valve control signal by a linkage unit 52.

In the embodiment shown in Fig. 1 ~ 4, the control signal of the electricity of the outside be fed into directly is used as valve control signal, and is directly connected to (durchschleifen) valve interface 47a, 47b.Relatively, dynamo-electric interface 53 is configured to the multi-pole type plug-in device allowing parallel signal transmission.

By contrast, the embodiment of Fig. 5 indicates a kind of modification, and wherein a linkage unit 52 is configured to fieldbus unit, or containing fieldbus unit, wherein dynamo-electric interface 53 is designed to field-bus interface, and field-bus interface is designed to serial signal transfer.

But under any circumstance all preferably the interface 53 of electromechanics is configured to connector interface, can connect by connector process the cable linkage unit 54 realized with the form of connector linkage unit.

Valve interface 47a, 47b non-immediate from a linkage unit 52, but obtain its valve control signal from connect in the middle of each first or the second two linkage units 56a, 56b.One time linkage unit 52 is electrically connected with two secondary linkage units 56a, 56b, wherein be connected with the first two linkage unit 56a by the connection wire 57a of the first inside, be connected with the second two linkage unit 56b by the connection wire 57b of the second inside.In a linkage unit 52, valve control signal is divided into thus for the first two linkage unit 56a valve control signal and be used for the valve control signal of the second two linkage unit 56b.

The mode of described division is, only has to specify to arrive the first two linkage unit 56a for the valve control signal of the first valve interface 47a, and only has and specify the valve control signal for the second valve interface 47b to transfer to the second two linkage unit 56b.

By preferred flexible manipulation cable in corresponding secondary linkage unit 56a, 56b and valve interface 47a, 47b between be electrically connected corresponding with it.Exactly, the manipulation cable 58a of the first electricity extends the first valve interface 47a from the first two linkage unit 56a, and the manipulation cable 58b of the second electricity extends the second valve interface 47b from the second two linkage unit 56b.

In order to be connected to relevant secondary linkage unit 56a, 56b, the manipulation cable 58a of all first electricity connects with the first cable linkage unit 59a that its one end is same together, in addition, the manipulation cable 58b of all second electricity connects with the second cable linkage unit 59b that its one end is same together.Only stretch out the manipulation cable 58a of the first electricity thus from the first common cable linkage unit 59a, only stretch out the manipulation cable 58b of the second electricity from the second common cable linkage unit 59b.

First common cable linkage unit 59a contacts with the first two linkage unit 56a, and the second common cable linkage unit 59b contacts with the second two linkage unit 56b.

The connection of cable linkage unit 59a, 59b and secondary linkage unit 56a, 56b can not disconnect and maybe can disconnect.The connection that can disconnect for reequiping fast (Umr ü stung), to meet the valve cell assembled condition of change.In both cases advantageously, cable linkage unit 59a, 59b are configured to plug unit, particularly construct according to the mode of multipole plug unit, thus by once all electrical connections be set up or be interrupted to simple connector process or drawing process can.

In order to be connected to valve interface 47a, 47b, the end opposed with common cable linkage unit 59a, 59b of manipulation cable 58a, 58b of each electricity is equipped with the connection set of the electromechanics of especially connector arrangement 62 form.Arrange independent connector arrangement 62 preferably to manipulation cable 58a, 58b of each electricity here.But also can unlike this, and multiple or all corresponding with longitudinal side 33 or 34 connector arrangement 62 be jointly assembled in a connector connecting plate.

Connector arrangement 62 is through special structure, and make it have multiple receiving bore, when connector is to valve interface 47a, 47b, the contact pilotage be arranged on related valves interface is inserted in described receiving bore.

Two secondary linkage units 56a, 56b are preferably co-located in the join domain 63 of control valve unit 100, before this join domain is positioned at the front 35 of valve group 32.Secondary linkage unit 56a, 56b and valve group 32 are correspondingly along orientation 28 arranged in succession.

In join domain 63, two secondary linkage units 56a, 56b preferably arrange transverse to orientation 28 side direction with offseting one from another.Make the first two linkage unit 56a near the first longitudinal side 33 thus, the second two linkage unit 56b are near the second longitudinal side 34.In this way can from which appointment be clear that above electric manipulation cable 58a, 58b for the first valve interface 47a, which is specified is used for the second valve interface 47b.

Although side direction staggers, in order to keep transverse dimension little as far as possible, feasible mode is, two secondary linkage units 56a, 56b is arranged in orientation 28 with offseting one from another, makes them overlap transverse to orientation 28 simultaneously.

Observe towards connection side, two secondary linkage units 56a, 56b preferably have elongate shape (L ngsgestalt), and through directed especially, their longitudinal axis is stretched perpendicular to orientation 28, is particularly parallel to and preferably also stretches transverse to the longitudinal axis of (l nglich) valve cell 27 of the lengthwise of orientation 28.The connection side of secondary linkage unit 56a, 56b particularly upwards towards.

Advantageously, a linkage unit 52 is also positioned at aforesaid connecting zone 63.It particularly can be close to two secondary linkage units 56a, 56b there and arrange.The connection side of a linkage unit 52 preferably also upwards towards.If the interface 53 of the electromechanics arranged is multi-pole type connector arrangement, then it preferably has elongate shape, and through directed, makes its longitudinal axes parallel in the longitudinal axis of preferred also secondary linkage unit 56a, 56b of lengthwise.

In order to get at a linkage unit 52 best, to be convenient to be connected with a cable linkage unit 54 and disconnect, according to the arrangement recommended, be located on the side opposed with valve group 32 in orientation 28 of two secondary linkage units 56a, 56b.In other words, so two secondary linkage units 56a, 56b are in the region between valve group 32 and a linkage unit 52.

Before two secondary linkage units 56a, 56b are arranged in valve group 32 by orientation 28, advantageously can handle cable 58a, 58b to draw respectively there first and second thus to lay, first they are laterally drawn transverse to orientation 28 through the front of valve group 32, next laterally extends along two longitudinal side 33,34 on the direction of orientation 28 in the outside of valve group 32.All manipulation cable 58a, 58b are preferably arranged at this height region hidden by valve group 32, thus manipulation cable 58a, 58b all do not cross (ü berqueren) whole valve group 32, and can keep getting at described valve group from top without any problems for possible operation measure.

Each manipulation cable 58a, 58b can have substantially L-shaped trend from secondary linkage unit 56a, 56b of arranging to the connector arrangement 62 arranged, and wherein particularly can see (vermitteln) this L shape in the plan view of the control valve unit 100 observed according to the view directions of arrow II.

In principle, the no matter manipulation cable 58a of the first electricity, or the manipulation cable 58b of the second electricity can be uncorrelated independent cable.But, as in the present embodiment, whole first manipulation cable 58a gather the first composite cable (Kabelverbund) 64a of slivering pencil, whole second manipulation cable 58b gather the second composite cable 64b of slivering pencil, make installation work simplify widely thus and orderly (ü bersichtlich).

In the present embodiment, its implementation is, no matter first handles cable 58a, or the manipulation cable 58b of the second electricity, in the length sections extended between corresponding common cable linkage unit 59a, 59b and connector arrangement 62, all closely interfix in longitudinal side.Particularly produce the fixing of a kind of material fit here, its mode is, is molded together by the cable cover(ing) of various different manipulation cable 58a or 58b and produces connection integrally.Alternatively such as also can consider to adopt bonding connection.Also manipulation cable 58a or 58b belonging to same compound cable 64a or 64b can be banded together by so-called cable connector and become bunch of cables, described cable connector surrounds the manipulation cable of all arrangings circlewise at the position of axially spaced-apart.

Each composite cable 64a, 64b are preferably also containing at least one earth cable (Massekabel) 65.Earth cable can adopt the mode identical with manipulation cable 58a or 58b arranged to be incorporated in related compound cable 64a, 64b.Such as only draw a unique this earth cable 65 from each common cable linkage unit 59a, 59b, its the other end is connected with one of connector arrangement 62, from here, by other "Jumper" cable 66 by other connector arrangement 62 ground connection (Masseverbindung) all.

"Jumper" cable 66 can also be responsible for connector arrangement 62 corresponding with same compound cable 64a or 64b respectively to interfix at certain relative position.Need relatively to mention, the length being summarised in manipulation cable 58a or 58b in composite cable 64a or 64b is preferably divided into step, thus manipulation cable 58a or 58b extending identical longitudinal side 33 or 34 respectively extends along valve group 32 in the region of longitudinal side 33,34 with different distances respectively.Described length, through selecting, makes each manipulation cable 58a or 58b extend to the axial region at valve cell 27 place to be connected.Manipulation cable 58a, 58b of extending the valve cell 27 of foremost are thus short than the manipulation cable of the valve cell 27 extended subsequently, and so on.

The connector arrangement 62 being arranged on cable end place is made to arrange abreast along the distribution arrangement 67 being parallel to orientation 28 stretching, extension shown in dotted line in this way.

Handle on one of cable 58a or 58b because each connector arrangement 62 is fixed on, in addition, adjacent connector arrangement 62 is interconnected by "Jumper" cable 66, thus need to be placed in the relative corresponding relation between the connector arrangement 62 in identical longitudinal side 33,34 relatively stable fix.This corresponding relation is responsible for can not mistaking when first or second valve interface 47a, 47b place connects and belongs to manipulation cable 58a or the 58b of same compound cable 64a, 64b especially.

A linkage unit 52 and two secondary linkage units 56a, 56b are preferably assembled in the connecting body 68 of a shell type.In the present embodiment, this connecting body is arranged in the region before valve group 32, is particularly fixed on valve seat 29.Such as, connecting body 68 is placed on mating face 30, and is tightened with valve seat 29 by one or more set screw 71.These set screws 71, through special structure, make them pass valve seat 29, and also have a kind of dual functions, namely also can be used for whole control valve unit 100 to be fixed on the bearing structure 72 shown in dotted line.

In addition, connecting body 68 can certainly be fixed on valve seat 29 independent of the installment state of valve seat 29, such as, be fixed by independent set screw or by kayser bindiny mechanism.

Fig. 6 and 7 illustrates the special scheme by already described internal connecting wire 57a, 57b, various different linkage unit 52,56a, 56b being carried out to internal wiring respectively with circuit diagram.

Can see a linkage unit 52 respectively, it has a contact 73 of multiple electricity, is 24 in the present embodiment, the valve control signal that these contact exports the control signal based on the electricity from outside feed-in in inside and produces.Additionally also have at least one earthed contact 75, it has two in the present embodiment.

The first two linkage unit 56a contain the secondary contact 74a of the first electricity of some, and the second two linkage unit 56b are equipped with the secondary contact 74b of the second electricity of some.In addition, each secondary linkage unit 56a, 56b are preferably also containing at least one earthed contact 76, and it has two in the present embodiment.

By the first already described internal connecting wire 57a, the secondary contact 74a of all first electricity is connected with one of contact 73, and in addition, each the second two contact 74b are also connected with one of contact 73 respectively.

In addition, respectively by earth lead 77a, 77b of at least one inside, between each earthed contact 76 and at least one earthed contact 75 of a linkage unit of two secondary linkage units 56a, 56b, produce inner electrical connection.

The way of realization of internal connecting wire 57a, 57b and inner ground wire 77a, 77b is preferably wire group, and it is configured on the carrier of such as circuit board form.But also can consider to be realized by flexible cable.

In the embodiment shown in fig. 6, each secondary linkage unit 56a, 56b have secondary contact 74a, 74b of the multiple first or second electricity, and the quantity of these secondary contacts equals the half of a contact 73 of a linkage unit 52.The secondary contact 74a of each first electricity is connected with attaching troops to a unit specially in its contact of a linkage unit 52 with the secondary contact 74b of each second electricity, thus each contact 73 is only connected with secondary contact 74a or 74b.

Manipulation cable 58a, 58b of the first or second electricity of equal number respectively can be connected in this way on two secondary linkage units 56a, 56b.Thus according in the design proposal of Fig. 6, the valve cell 27 that 12 are respectively equipped with two valve interfaces 47a, 47b can be connected.If a valve cell 27 only has a first valve interface 47a, then only use the secondary contact 74a of whole electricity of the first two linkage unit 56a, the unwanted secondary contact 74b of the second two linkage unit 56b then keeps need not.This means on final effect, and control valve unit 100 no matter its valve cell 27 only has one or have two valve interfaces 47a, 47b, and the quantity of the valve cell 27 that it can assemble equals at most the half of an existing contact 73.

Self-evident, the quantity of 24 contacts 73 in the present embodiment is only an example, also can have a contact of other quantity in principle, thus also can have the secondary contact of other quantity.

In the circuit design drawing of the control valve unit 100 according to Fig. 7, the utilization power of an existing contact 73 obtains remarkable improvement.Be different from the embodiment of Fig. 6, here, the quantity of the secondary contact 74a of the first electricity equals the quantity of a contact 73 of electricity.Be connected with a this contact 73 respectively by means of a linkage unit 52 compared to the secondary contact 74a of the first electricity that Fig. 6 adds existence, this contact is also connected with the second two contact 74b of the second two linkage unit 56b.Therefore, the a contact 73 dual use (Doppelbelegung) at least in part as follows of electricity a: contact 73 of each dual use was both connected with the first two contact 74a of the first two linkage unit 56a, is connected with the second two contact 74b of the second two linkage unit 56b again.

Such as, the quantity of the first two contact 74a is the twice of the second two contact 74b, thus the half of existing the first two contact 74a contacts with a contact 73 respectively, and contact is connected with the second two contact 74b simultaneously.

Therefore, according to the embodiment of Fig. 7, assemble multiple valve cell 27 respectively having two valve interfaces 47a, 47b can to control valve unit 100, the quantity of these valve cells equals the half of an existing contact 73.Be 12 in the present embodiment.But in addition, due to an a part dual use in contact 73, except each valve cell 27 only having a first valve interface 47a, another this valve cell 27 being only equipped with a first valve interface 47a can also be installed.So this additional valve cell 27 can connect with the first two the contact 74a being connected to an identical contact, and can be connected with the second two contact 74b no when lacking the valve cell 27 of bistable of respective numbers.

Thus each valve cell 27 being equipped with the bistable of two valve interfaces 47a, 47b can be replaced, the monostable valve cell 27 that two are all only equipped with a valve interface 47a is installed when needed, so a contact 73 of the electricity of all existing quantity can be utilized to carry out electric control to all valve cells.

Self-evident, each required quantity handling cable 58a or 58b can conform to corresponding demand.In the embodiment shown in Fig. 1 ~ 5, the quantity handling cable 58a with three monostable valve cells 27, first being equipped with three bistables respectively is correspondingly also greater than the quantity of the second manipulation cable 58b.It is advantageous that for corresponding applicable cases, composite cable 64a, 64b of maintaining respective design are available.But this composite cable also can separately make as the case may be.

The useful order of placement of valve cell 27 is, starts with the front in the SCCP connection-oriented region 63 of valve group 32, first arranges the valve cell 27 of bistable, then just arranges monostable valve cell 27.
