In this connection it is desired to obtain a self-acting behaviour with small space requirements. For this purpose, the adjusting device (7) has a control device (9), arranged laterally next to the housing (2) and detachably connected with the housing (2).
Description
The present invention relates to a thermostat valve header, it has a shell and a thermostatic element, this thermostatic element links to each other with an operating element by a connecting element, and this thermostat valve header also utilizes an adjusting drive unit to change effective connection between this operating element and this thermostatic element.
Such thermostat valve header can be learnt from patent DE3153654C2.In this known top, the length that is used as the pillar of connecting element between thermostatic element and heating valve mandril changes, and wherein an oval plate both can its major diameter also can be inserted between pillar and the push rod by its minor diameter.For this purpose, this oval plate is supported by floating ground, and by a gear by a motoring that laterally is installed on the intermediate member, this just needs this oval plate is placed between this pillar and the push rod.With regard to this embodiment, require this thermostat top to expand vertically, that is to say, further stretch into indoor from radiator.Because the increase of these lever contacts just exists the danger of damage.
Using such thermostat top component is in order to change the hope numerical value of this thermostatic element on the spot.For example, can wish to set the readjustment at night of temperature in the room, this desired value is reduced, for example, 1-5 ℃.In above-mentioned patent DE3153654C2, this pillar is just correspondingly reduced at that time, thereby the valve of this radiator is just closed or throttling earlier for identical room temperature.
In patent DE3545232A1, a kind of different possible method that changes room temperature is disclosed.Here, a control gear is placed in the front side of this thermostat valve header, this control gear has a pressure transducer that acts on this thermostatic element.The pressure that is produced and be delivered on the valve mandril by higher temperature in this thermostatic element is replaced by a mechanical pressure.But this embodiment is quite expensive.It has also increased actual size and has reduced the operation convenience of this thermostat valve header.In addition, it also can make this thermostatic element produce serious strain.
The present invention is based on that following task puts forward: the thermostat valve header can be moved automatically but keep less actual size.
For a thermostat valve header, this task makes that this controlling device has adjacent this shell configuration and achieves a solution with control gear that this shell removably links to each other.
This embodiment comprises several advantages.The use of control gear just can make this thermostat valve header control automatically by the mode of this controller regulation.For this purpose, this control gear can comprise, for example, and a timing recloser or a program control processor.Effective connection between this thermostatic element and this operating element just by the time, also can be regulated by other condition at that time, takes which kind of regulative mode relevant with embodiment.For example, for this control gear, also can by this control gear these signals be handled then from the central location received signal.The advantage that the layout of adjacent this shell has is that the requirement space is little.It is indoor the thermostat top further to be put in.The meaning of " adjacent shell side " is meant that this control gear is not along the continuous installation at thermostat top, but is installed to the thermostat top along radially the medial axis of this shell (for example with respect to) at thermostat top.At last, above-mentioned removably connecting also comprises a lot of possible methods.At first, it only means needs seldom strength and preferably without instrument, just this control gear can be disassembled also and can install again again from this thermostat valve header or its shell with operation once or twice usually.Control gear can be replaced each other.This control gear can be set under disassembly status, this means significantly improving of travelling comfort.Usually, these thermostat valve headers all are mounted in and are on the radiator on the height suitable with people's buttocks.Setting on the spot, for example, during programming, usually only may carry out under the quite uncomfortable attitude taking.But in the time this controller may being unloaded down, programming or setting just can cosily be finished, and for example, set on desk, and then the control gear that will configure fully are reinstalled onto this thermostat top.
Preferably, the certain operations element is installed in the side of this control gear towards this shell.This embodiment has two advantages.At first be that it can make this controller have a pleasing outward appearance.Just, can be closed remaining in outer control gear, but also can make it to have a smooth surface.This also is convenient to the cleaning of this controller.The second, under installment state, this operating element all is covered, thereby is protected.So just can highly avoid the change that is not intended to for this controller.
Best, this operating element has a display device, but also provides a switch, and this switch just can be shut this display device when this control gear and shell are connected to each other, and just this display device can be opened when they are separated.This display device makes the user can see these settings that he does this control gear.Therefore, this display device only should can actually see that it is only demonstration the user.When this control gear was fixed on this thermostat valve header, situation was not like this.Under the sort of situation, so just this display device can be closed, this just can save electric current significantly.Especially when the energy that only provides battery to be used as this control gear, the life-span of this battery just can be by this possibility method significant prolongation.Close and open control gear and all automatically take place, it is to be associated with the installation of this control gear on this thermostat valve header, thereby the user can not get wrong.
Preferably, this control gear is to be connected and will to be joined to one another by a snap-fastener with this shell, and this connection has the engaging surface under at least one barb and, and they can move mutually.For this control gear is installed on this thermostat valve, it need only be pushed away towards this top casing direction, be combined in the back of this engaging surface up to these reverse grafts.Usually, this is to detect by clatter easily.Such installation is very simple, and also can be finished easily by unskilled persons.In order to unload this control gear from this shell, this engaging surface and this overhead kick must relatively move, so that discharge this overhead kick.But this also can very successfully accomplish.
In this connection, preferably this overhead kick is to be placed on the rigid lever, and this engaging surface is movably.Such connection can be a quite stable.When being placed in this overhead kick on one rigid lever, it should no longer include elasticity, this means that this lever may have sizable size.Since this rigid lever is not easy to be bent, this assembling has just been simplified.In order to unclamp overhead kick, can be simply, for example, the method for pushing by the power that heads on Returnning spring moves this engaging surface and gets final product.
In this connection, especially preferably, this overhead kick is positioned on the shell, and this engaging surface is positioned on this control gear.Be particularly advantageous for stability.
Preferably, this overhead kick is loaded the operating element of the switch of closing as this by spring force.Like this, just do not need other element to operate this switch.
Preferably, this snap-fastener connection has two overhead kicks, and this two overhead kick is to be symmetrical in by the plane of this shell medial axis to settle basically.This has just simplified installation, and need not leave connection stability.
Advantageously, between this control gear and this shell, also provide another overhead kick to connect.This has just improved eye impressions.It no longer needs this overhead kick is placed in the center of gravity zone of this control gear.And when being placed in this zone when outer, this additional overhead kick connection can closely be connected this control gear on the shell of this thermostat valve header.This overhead kick connects also, and a snap-fastener connects.But, also the overhead kick that this overhead kick connects can be suspended in the shell, then with the direction inclination of this control gear towards this shell, the back of sharing this engaging surface up to this reverse graft.The meaning that term " blocks connection " is that this connection only need be adopted pulling force.
Preferably, this controlling device has the gearing with an insertion gear, and this gear is fixed on this shell and by a notch and stretches out from this shell, and this control gear also has a notch, and this insertion gear just enters this control gear by this notch.Like this, just can select sizable insertion gear diameter, so as with quite few number of gears just can be in control gear motor and the controlling mechanism in the shell between obtain a big gear ratio.Can make this insertion gear support in shell have sizable stability.Because control gear is connected on this shell, so the connection from the motor of control gear to suitable controlling mechanism all can realize simply.
In this connection, especially preferably, this overhead kick is to be placed on the height identical with inserting gear basically.When the motor of this control gear of starting when rotating this insertions gear, actual appearance that Here it is is unique must be by the place of this mechanical load of accepting of removably connecting.Overhead kick is placed in to help avoid on the height identical with this gear that big heeling moment between this control gear and shell, occurs.
As described, the invention still further relates to a control gear as thermostat valve header annex.This has following advantage, can be a thermostat valve header so several different types of control gear are provided, and these control gear have identical mechanical embodiment, but have different control characteristics.This has just increased the flexibility of this thermostat valve header.
Below, will come the present invention is described according to several preferred embodiments and following accompanying drawing:
Fig. 1 one is equipped with the side view of the thermostat valve header of control gear;
Fig. 2 is the top view that control gear is removed this thermostat valve header that comes;
Fig. 3 is the schematic cross-sectional view that an expression snap-fastener connects;
Fig. 4 is the view that snap-fastener connects the device shown in Figure 3 engaged;
Fig. 5 is the side view that control gear is removed this thermostat valve header that comes;
Fig. 6 is the view towards the control gear side of thermostat valve header;
Fig. 7 is the detailed drawing that an overhead kick connects;
Fig. 8 is the view that is in the overhead kick connection shown in Figure 7 of coupled condition.
Fig. 1 represents that one has the thermostat valve header 1 of shell 2, and it can be fixed on the radiator valve (carefully not drawing) by a union nut 3 or other suitable link.Functional part in this thermostat valve header only schematically dots.This thermostat valve header has a thermostatic element 4, and it just promotes pillar 5 (with respect to the direction in Fig. 1) downwards when heating.This pillar 5 touches the operating element 6 on the push rod (carefully not drawing) that is pressed in this radiator valve again.This push rod is inwardly pushed away manyly more, and then this radiator valve is many more with regard to throttling.At last, provide the device 7 that can change this column length.The change of this column length can make the effective connection between this thermostatic element 4 and this operating element 6 change.Under the ambient temperature that others all do not have to change, this pillar is long more, then this radiator valve with regard to throttling more early.For example, can set the readjustment at night by this elongation.
For example, the desired value of this thermostat valve header can pass through a rotatable handle 8 preset.But, also can only change this desired value by installing 7.
In the side of this shell 2, a control gear 9 is removably linked to each other with this shell 2.In this connection, the device that is parallel to pillar 5 in the side that is to say, this installs not on the elongation line of this pillar, thereby the installation of this control gear 9 can not cause that the axial length of this thermostat valve header changes.
This control gear 9 connects by a snap-fastener and links to each other with this shell 2.This snap-fastener connects can come detailed explanation by Fig. 3 and Fig. 4.Owing to be that this snap-fastener connects, thereby just might this control gear be unloaded down, then can equally simply it be installed again by once-through operation.
This shell 2 has two overhead kicks 10, and each overhead kick all is the end that is placed in rigid lever 11.This rigid lever 11 is very stable, so that they can both bear the weight of this control gear and can not be out of shape.But when standing bigger power, this lever also is possible deformation.These levers 11 can be the working of plasticss of making on this shell.
This control gear 9 has a shell 12, and this shell 12 has two openings 13 (Fig. 6) that are used for accepting overhead kick 10.In the back of each opening 13 slide block 14 is arranged all, this slide block by a pressure spring 15 to extrapolation.In its outside, this slide block 14 forms a button 16, and this button can be pushed into this shell 12 towards the direction of arrow 17.
Deviate from the side of shell at this slide block, an engaging surface 18 is arranged, this overhead kick just is bonded on the back of this slide block.When the shell 12 of this control gear (9) must link to each other with the shell 2 of thermostat valve header 1, the control gear 9 that just will have opening 13 was connected the end of this overhead kick 10.When with this control gear 9 when the direction of shell 2 moves, this slide block 14 moves inward with regard to the elastic force that heads on spring 15.As long as this overhead kick 10 has moved past this slide block, slide block 14 will be stuck in the back of this overhead kick, thereby this overhead kick 10 just is bearing on this engaging surface.Because this lever 11 has very stable structure, so this method just makes this control gear 9 enough technology that stably are fixed on this shell 2.
In this control gear 9, a switch 19 is installed, this switch has a mobilizable element 20 and a contact 21.As shown in Figure 3, when with this control gear 9 when this shell 2 is removed, this movable element 20 just is bearing on this contact 21.But when connecting (Fig. 4), the end of this overhead kick 10 just pushes away this moving element this contact 21, has so just interrupted the electrical connection of these two parts.
This control gear has a motor 22, and only with dashed lines is drawn among Fig. 1.This motor 22 drives a small gear 23, and this small gear acts on the insertion gear 24, just can see that in Fig. 2 this inserts gear.This insertion gear 24 be supported in this shell 2 and be placed in the same height of lever 10 on.Like this, this lever 10 just is positioned in the both sides of this insertion gear 24.When this motor acts on the gear 24 by small gear 23, some power will appear, and these power can make the snap-fastener between control gear 9 and the shell 2 connect distortion.But these power but can't cause the torque that this control gear 9 is rotated with respect to shell 2.
Especially can see that in Fig. 6 this control gear has the opening 25 of a notch sample, this gear 24 can enter in this control gear by it when mounted.One when being connected to form between this control gear 9 and this shell 2, then between this motor 22 and this device 7 also even connected.In this application, because gear just can be accomplished this point by mobile in opposite directions being engaged with each other radially.
Schematically the drawn view of this side of control gear 9 of Fig. 6 just is bearing on the shell 9 at this control gear on the installment state.This side has certain operations element 26, just a display device 27, a switch plate 28 and several button 29.This display device can be closed by switch 19.This can save electric energy, and when this control gear 9 when being battery-powered, this is with regard to advantageous particularly.Like this, after control gear 9 was installed, this display device 27 was just always closed.In this situation, the user is any information on the reading displayed device more in any case.When this control gear was installed, this switch 28 and all buttons 29 also all were protected in order to avoid be not intended to touch.
For the orientation of Fig. 1 and 5, this overhead kick 10 is positioned on the quite high position on this control gear 9.For fear of under installment state, distance appears in the zone below between this control gear 9 and shell 2, provide another overhead kick at this, as shown in Figure 7 and Figure 8.These two figure are illustrated in the cross section of the A-A line intercepting of different erection stage upper edge Fig. 5.
In the shell 12 of control gear 9, another opening 30 that provides two bottoms to be limited by an inclined-plane 31 is installed so that simplify.One overhead kick 32 is arranged on shell 2, in the opening 30 of it can being packed into so that hang over the back of shell wall part 33.Here the confining force that is adopted is quite little.They need only separate just with this shell 2 even as big as preventing this control gear 9.
On the other hand, this thermostat top 1 also can operate as a traditional thermostat top now.Can set in advance temperature desired by rotatable handle 8.For this purpose, do not need to install this control gear 9.
But behind installation and control device 9, this thermostat valve header has just increased some for example can carry out regulating night on the spot the possibility of readjustment to a radiator.
When the user is ready to postpone or changes readjustment at this at night, then he just pushes this button 16 and takes off this control gear from shell 2, can change programming by those operating elements 26 afterwards, and can again this control gear 9 be loaded onto, and couples together with shell 2.This process is very easily to the user.Also seldom failed.
