Definitions
- the invention relates to an actuation attachment for actuating a heating valve with a housing having a drive section and a mounting section with a mounting geometry for connection to a heating valve.
- Such actuation attachments serve to be able to adjust the flow through a heating element and thus the desired heat output.
- Actuating attachments are e.g. used for wall radiators or for underfloor heating distributors.
- the actuating attachment controls the position of a closing element of a heating valve via an actuating element.
- the actuator must therefore be connected to the heating valve.
- the mounting geometries of the valves available on the market are not standardized, so that actuators and heating valves of different manufacturers can not be combined in the rule.
- the invention is based on the object to provide an actuating attachment, which allows easy adaptation to heating valves with different mounting geometries. According to the invention this object is achieved in an actuating attachment of the type mentioned above in that the attachment portion is detachable.
- the drive section surrounds an electric actuator which is connected to an actuating element.
- the actuating element serves for actuating a closing element of the heating valve.
- An electric actuator has the advantage that a zero point calibration can only be carried out after the actuation attachment has been mounted on the heating valve. In contrast to conventional thermostatic attachments, it is not necessary to know the exact axial position of the closing element of the heating valve. Since the actuator is surrounded by the drive section, the if necessary, also be used without attachment section, wherein the connection point of the drive section and mounting portion then represents the corresponding Befest Trentsgeo-metry for connection to a heating valve. The drive section is then connected, for example, directly to the heating valve.
- the attachment portion has an axial extension received in one end of the drive portion.
- a relatively large area is available for the connection between the fastening section and the drive section, so that a secure connection is obtained. Tilting between the two sections is almost impossible.
- an external thread is arranged on the axial extension, which cooperates with an internal thread at the end of the drive section.
- the external thread and the internal thread thus represent a thread pairing.
- Such a thread pairing allows a reliable, but detachable connection between the drive portion and the attachment portion.
- this can be advantageous, since it can be ruled out by unauthorized persons.
- the attachment portion and the drive portion are connected to each other via an intermediate ring.
- the attachment portion and the drive portion are therefore not directly connected to each other, but indirectly via an intermediate ring.
- an internal thread which is intended to interact with the external thread on the extension can be formed on the intermediate ring, so that the drive section itself can be constructed relatively simply.
- an intermediate ring can be favorable, since this can then be formed of a material which harmonizes with both the material of the fastening portion and with the material of the drive portion.
- the intermediate ring is held in the axial direction in the drive section and rotatable in a rotational direction, wherein an opposite direction of rotation is locked.
- the intermediate ring not only has the function to connect the attachment portion with the drive section, but also serves as a safeguard against unintentional release. While, for example, in the direction of unscrewing of the actuating attachment to a valve, the intermediate ring is not rotatable relative to the drive section, so that the screwing-on movement is transmitted, in the opposite direction, ie a unscrewing direction, transmission of the rotational movement from the drive section via the intermediate ring is not readily possible. An unauthorized release of the drive portion of the mounting portion is thereby reliably prevented. A unscrewing of the actuating attachment of a heating valve is at least difficult because the attachment portion usually does not have a large enough attack surface for the introduction of radial forces.
- the intermediate ring on radially outwardly projecting locking projections, which engage in an annular groove in the drive section.
- the latching projections may have inclined contact surfaces on one side.
- An opposite side may be formed as a holding side, which cooperates with one side of the annular groove and thus prevents removal of the intermediate ring by means of positive locking.
- the intermediate ring on a radial slot This radial slot allows elastic deformation of the intermediate ring, in particular an elastic reduction of the diameter of the intermediate ring during insertion of the intermediate ring in the drive section.
- the locking projections ge can then be made relatively stable, since no elastic deformation of the locking projections must be made to insert the intermediate ring.
- the intermediate ring on tabs that allow movement in one direction of rotation and lock in the other direction.
- These tabs thus act as pawls, wherein they interact with corresponding formations in the drive section, in particular in the annular groove of the drive section. They represent a relatively easy way to lock one direction of rotation while the other direction of rotation is released.
- sufficiently high torques can then also be transmitted in one direction of rotation, so that a fixed screwing of the intermediate ring to the fastening section and, if appropriate, of the fastening section can take place with a heating valve, wherein the screwing forces are introduced via the housing of the drive section.
- the intermediate ring on axial recesses.
- These axial recesses may also be formed continuously in the form of passage openings.
- the recesses can be used to engage a tool to get an anti-rotation of the intermediate ring relative to the drive section in both directions, so that the drive section with the intermediate ring from the mounting portion can be.
- a compartment for a power source is provided in the drive section, said compartment having a through opening, through which a tool with at least one recess can be brought into engagement.
- the attachment portion has an annular groove which surrounds the extension, wherein the intermediate ring extends axially into the annular groove.
- annular groove may be formed so that a certain bias is applied to the intermediate ring, so that a thread play in the thread pairing between intermediate ring and mounting portion is minimized.
- an elastic reduction of the diameter of the intermediate ring is prevented by the annular groove, so that the latching projections can not inadvertently come loose from the annular groove of the drive section.
- a reducing element is used in the attachment geometry.
- a correspondingly formed attachment section By means of a corresponding reducing element, it is then still possible to connect these heating valves to the actuating attachment. The possible applications of the actuation attachment are thus expanded.
- the extension has a lid, in which an opening for a valve tappet is formed.
- the valve stem is usually firmly connected to the closing element of a heating valve.
- the lid with the opening allows a guide of the valve stem. Cross loads on the valve lifter can be avoided.
- the interior of the actuating attachment is closed except for the opening by the cover. A contamination of the actuation attachment, for example, during transport, is very difficult.
- an extension element is guided in the opening, which cooperates with the actuating element. The required travel of the actuator can then be kept relatively small, since too large a distance between the actuator and the valve stem and the closing element of the heating valve, which can be caused by the corresponding configuration of the mounting portion is compensated by the extension element.
- the extension element causes, so to speak, a zero shift and thus a calibration of the actuating attachment.
- the extension element has at its ends in each case a radial formation, which extends radially further than the opening, wherein an axial distance between the formations is greater than a thickness of the lid.
- the extension element is thus held in a form-fitting manner in the opening of the cover, wherein nevertheless an axial movement of the extension element is possible.
- the radial formations may be formed, for example, as circumferential collar, wherein at least one molding may be elastically deformable to allow easy insertion of the extension member in the opening of the lid. The extension element is thereby secured against being lost.
- the extension element has at least one cone-shaped end.
- This cone-shaped end facilitates insertion of the extension element into the opening of the lid.
- the radial formation, which is arranged on the cone-shaped end be elastically deformable.
- the extension element can be inserted relatively easily into the opening due to the conical design, removal is much more difficult.
- the extension member has a cylindrical cavity open to one of the ends. This cavity can serve for example for receiving the valve stem. Between the valve stem and the extension element then results in a reliable connection. Of the Cavity may be open to the end, which is opposite to the cone-shaped end.
- an outer diameter of the attachment portion corresponds to an outer diameter at the end of the drive portion. This results in a smooth surface of the housing. If necessary, it is hardly recognizable that the attachment portion is releasably secured to the drive portion. At the same time, the risk of contamination, which preferably occurs at projections, kept small.
- a securing element for securing the fastening portion is arranged in the drive section. A loosening of the fastening portion is then possible only after loosening or removing the fuse element. Unintentional or autonomous release, for example due to vibrations, is effectively prevented by the securing element.
- the attachment geometry is designed as a circumferential groove.
- the actuator can then be easily set, for example by means of a spring ring on the heater valve.
- this has the advantage that a rotation of the actuating attachment when connecting to the heating valve is not required.
- the circumferential groove is disposed on an inner side of the attachment portion, the attachment geometry is also almost invisible in the mounted attachment portion. This makes a very harmonious appearance possible.
- the attachment geometry is formed as a cylindrical cavity, wherein the attachment portion has a clamping element.
- the heating valve is thus simply inserted into the cylindrical cavity, the actuating attachment then being secured by means of the clamping element.
- a cylindrical cavity can be produced with relatively little effort.
- in the cylindrical hollow cavities also be formed, which serve as a contact surface for the heating valve.
- the fastening geometry preferably has an anti-rotation lock.
- the radial orientation of the actuator with respect to the heater valve is thereby defined. For example, it can be ensured that an inscription on the actuating element is always readable.

- the attachment portion 4 has a mounting geometry 6 for connection to a heater valve, not shown, which is formed in this embodiment as a cylindrical cavity.
- the drive section 3 surrounds an electric actuator 7, which has an output shaft 8. Rotationally fixed to the output shaft 8, a gear 9 is connected, which cooperates with an actuating element 10.
- the actuator 10 has for this purpose on its peripheral surface on a tooth structure.
- the actuating element 10 is held in the housing 2 via a thread pair 11. The rotational movement of the actuating element 10, the from
- Actuator 7 is transmitted via the output shaft 8 and the gear 9 is converted by the pair of threads 11 in a linear adjusting movement.
- the actuating element 10 is thus movable in the direction of the attachment portion to or away. With the aid of the actuating element 10, therefore, a corresponding closing element of the heating valve can be actuated, so that a flow rate is increased or decreased.
- a trained as a battery 12 energy source is provided in this embodiment.
- Other energy sources are conceivable.
- the battery 12 is disposed in a compartment 28.
- the housing 2 is closed at its end facing away from the attachment portion 4 end with a closure piece 13.
- the end piece 13 is positively secured to the drive section 3.
- the drive section 3 can be relatively easily manufactured as a hollow cylinder.
- the end piece 13 can also be made detachable, for example, to allow easy replacement of the battery 12. It is also possible to provide an additional detachable lid for the compartment 28.
- the thread pairing 5 is arranged on an axial extension 14 of the fastening portion 4, wherein on the extension 14, an external thread 15 is embossed.
- the drive section 13 accordingly has an internal thread 16. The external thread 15 and the internal thread 16 thus together form the thread pairing. 5
- a section of an actuating attachment 1 is shown, wherein like elements are provided with the same reference numerals.
- the connection between the electric actuator 7 and the actuator 10 is slightly changed in this embodiment, so that the actuator 10 performs only a linear movement and no rotation.
- the principle is the same as in the embodiment of FIG. 1.
- a clamping element 17 is arranged in the attachment portion 4.
- the clamping element 17 is designed as a threaded pin which is inserted in a threaded bore 18 in the mounting portion 4.
- the biasing member 17 can be radially displaced into the cavity, thus exerting a biasing force on the heater valve. The heating valve is then not removable without loosening the clamping element 17.
- the drive section 3 has a securing element 19 for securing the fastening section 4, the securing element 19 being arranged at the level of the thread pairing 5 in the drive section 3.
- the securing element 19 is formed in this embodiment as a threaded pin, but the securing element 19 can not get into direct contact with the mounting portion 4. However, screwing in the securing element 19 causes a slight elastic deformation of the drive section 3 in the area of the thread pairing 5, so that the friction between the drive section 3 and the fastening section 4 is increased. A loosening of the fastening section 4 from the drive section 3 is made more difficult.
- a section of the actuating cap 1 is shown, wherein the mounting portion 4 is removed. If necessary, it is possible to directly to the injection valve 1 via the internal thread 16 of the drive section 3. The heating valve must then of course have a corresponding external thread.
- 4 shows a section of the actuating attachment 1, the attachment section 4 having an altered attachment geometry 6.
- the attachment geometry 6 is formed in this embodiment as a circumferential groove 20. About the groove 20, the actuation attachment 1 latching, for example, via a snap ring to be connected to the heating valve.
- the mounting portion 4 has compared to the embodiments shown in the embodiments 1 to 3 but still some other specifics. Thus, the mounting portion 4 is provided with steps 21 which serve as a plant for a heating valve.
- the attachment portion 4 has a cover 22 in which an opening 23 is arranged. In the opening 23, an extension element 24 is guided. The extension member 24 is in contact with the actuator 10 and is linearly moved by the actuator 10.
- the extension element 24 has at its ends in each case a radial Ausformation 25, 26, which are formed as circumferential collar.
- the actuating element 10 facing the end of the extension member 24 is formed cone-shaped.
- the radial formation 25 at the cone-shaped end has a smaller radial extent than the formation 26. Since the radial formations 25, 26 extend radially further than the opening 23, an elastic deformation of at least one of the radial formations occurs when the extension element 24 is inserted 25, 26 required. Conveniently, the smaller formation 25 is deformed.
- the insertion of the extension element 24 into the opening 23 is simplified by the conical end.
- the remote from the actuator 10 end of the extension member 24 has a cylindrical cavity 27 which is open on one side.
- The- ser cavity 27 serves to receive a valve stem or a closing element of the heating valve.
- a linear movement of the extension element 24 is limited by the formations 25, 26. However, since a distance between the protrusions 25, 26 is greater than a thickness of the lid 22, a sufficient adjusting movement is possible.
- FIG. 5 shows a second preferred embodiment of the actuating attachment 1, wherein unlike the previous examples, the drive section 3 is connected indirectly to the attachment section 4 via an intermediate ring 29.
- the same parts are otherwise provided with the same reference numerals.
- the intermediate ring 29 is held by latching projections 30 in an annular groove 31 of the drive section 3.
- the latching projections 30 are provided on their side facing the drive section 3 with an oblique contact surface.
- the opposite side of the latching projections 30 is formed as a holding side 32 which, together with the annular groove 31 prevents axial movement of the intermediate ring 29 from the drive section 3 out.
- the intermediate ring 29 is screwed via an internal thread 33 with the external thread 15 of the axial extension 14 of the mounting portion 4.
- a different type of connection for example a latching connection, can also be provided there.
- the intermediate ring 29 extends into an annular groove 34 which surrounds the axial extension 14.
- the drive portion 3 engages over the intermediate ring 29 axially so far that it rests radially in the region of the annular groove 34 on the mounting portion 4 from the outside.
- the intermediate ring 29 is therefore not visible from the outside. Rather, the drive section 3 appears to be connected directly to the attachment section 4. At the same time relatively large contact surfaces between the drive portion and mounting portion are available, so that a backlash-free connection is possible.
- the intermediate ring 29 is shown isolated.
- tabs 35 are arranged, which act as pawls and thus allow a direction of rotation and prevent an opposite direction of rotation of the intermediate ring in the drive section.
- recesses 36 are formed, which in this example are formed as through openings.
- the intermediate ring 29 has a radial slot 37, which allows an elastic deformation of the intermediate ring 29. When inserting the intermediate ring 29 into the drive section 3, the intermediate ring 29 can be radially reduced, so that the latching projections 30 can be inserted into the annular groove 31.
- Fig. 7 the intermediate ring 29 is shown in a slightly rotated representation, whereby it can be seen that the tabs 35 protrude axially with a free end.
- the tabs 35 can thus cooperate with corresponding projections, which are formed either in the drive section or in an end face of the fastening section 4, and thus lock a direction of rotation.
- At least one recess 36 can be brought into register with a passage opening 38, so that a tool can engage in the recess 36 through the compartment 28 and the passage opening 38. With the help of the tool, the hitherto free direction of rotation of the intermediate ring 29 can be locked, so that the drive portion 3 can be solved together with the intermediate ring 29 from the mounting portion 4.
- a reducing element 39 is arranged in the illustration according to FIG. 5. This reducing element 39 serves for further adaptation of the fastening section 4 to a heating valve.
- the attachment portion 4 may also be formed as in the preceding embodiments.
- actuation attachment 1 with its elements drive section 3, mounting section 4, intermediate ring 29 and reducing element 39 is shown isolated.
- intermediate ring 29 and the rear duzierelement 39 disposed within the actuation attachment 1 and not visible from the outside, so that a harmonious impression is obtained.
- the electric servomotor 7 has a zero calibration, whereby the knowledge of the exact axial position of the closing element of the heating valve is not required.
- the calibration can also be performed only after mounting the actuator. This makes it possible to provide the actuation attachment with a detachable or exchangeable attachment portion. With conventional actuation attachments, precise knowledge of the position of the closing element was required, so that it may have been necessary to arrange an adapter piece directly on the heating valve.
- the adapter piece then has a corresponding extension for the closing element or the valve tappet of the heating valve, wherein in turn a defined axial position was obtained by this extension.
- such an extension element can optionally be dispensed with.
- smaller differences can be compensated by the actuator and a calibration. It is thereby possible to provide the actuation attachment with detachable and replaceable attachment sections, so that a simple adaptation of the actuation attachment to different heating valves is possible. Additional adapters are not required.
