Description

Die Erfindung betrifft einen Ventilaufsatz mit mehreren Beinen, die an einem axialen Ende mit einem Träger verbunden sind, einen an einer Stirnseite offenen Aufnahmeraum in Umfangsrichtung umgeben und ein Gewinde an ihrer radialen Außenseite tragen, und mit einer Mutter, die auf das Gewinde aufschraubbar ist.The invention relates to a valve attachment with several Legs connected to a beam at one axial end are, a receiving space open at one end surrounded in the circumferential direction and a thread their radial outside, and with a nut, which can be screwed onto the thread.

Ein derartiger Ventilaufsatz ist beispielsweise aus DE 92 04 444 U1 bekannt.Such a valve attachment is, for example, from DE 92 04 444 U1 known.

Die Erfindung soll im folgenden anhand eines Heizkörperventils beschrieben werden, das mit einem Thermostatkopf versehen wird. Der Thermostatkopf ist am Ventilaufsatz befestigt.The invention is based on a radiator valve be described with a thermostatic head is provided. The thermostatic head is on the valve attachment attached.

Zur Montage wird der Ventilaufsatz auf das Ventilgehäuse des Heizkörperventils, das aus dem Heizkörper vorsteht, aufgeschoben. Hierbei müssen die Beine etwas radial nach außen federn können, insbesondere dann, wenn das Ventilgehäuse und die Innenseite der Beine aneinander angepaßte Strukturen aufweisen, beispielsweise Vorsprünge und Nuten. Damit die Beine diese radiale Auswärtsbewegung durchführen können, muß die Mutter abgeschraubt sein. Hierzu wird die Mutter üblicherweise auf den Bereich des Trägers bewegt, der der Stirnseite abgewandt ist. Andernfalls wäre ein Aufschrauben bei aufgesetzem Ventilaufsatz nicht mehr möglich.The valve attachment is mounted on the valve housing the radiator valve protruding from the radiator, postponed. Here the legs have to be somewhat radial can spring outwards, especially if the valve housing and the inside of the legs together have adapted structures, for example projections and grooves. So that the legs make this radial outward movement the nut must be unscrewed his. To do this, the mother is usually up moves the area of the carrier facing away from the face is. Otherwise it would be unscrewed with the on Valve attachment no longer possible.

Bei der Montage des Ventilaufsatzes ergeben sich allerdings gewisse Handhabungsprobleme. Die Mutter muß beim Aufsetzen des Ventilaufsatzes die radiale Bewegung der Beine ermöglichen. Sie muß also vom Gewinde nicht nur abgeschraubt worden sein, sondern auch weit genug von der Stirnseite entfernt worden sein, damit die Beine durch die Mutter nicht behindert werden. Wenn der Thermostataufsatz allerdings so montiert werden muß, daß die Stirnseite in Schwerkraftrichtung nach unten weist, dann fällt die Mutter aufgrund der Schwerkraft nach unten bis zum Gewinde und verhindert damit die radiale Auswärtsbewegung der Beine. Bei anderen Montagerichtungen muß die Mutter bei der Montage bis zum Gewindeanfang geschoben werden und im gleichen Arbeitsgang zum Eingriff mit dem Gewinde gedreht werden, bevor ein endgültiges Festspannen des Ventilaufsatzes am Ventilgehäuse erfolgen kann. Beides erschwert die Montage.When installing the valve cap, however, result certain handling problems. The mother has to Attaching the valve cap to the radial movement of the Allow legs. So you don't just have to remove the thread have been unscrewed, but also far enough from the front face should have been removed so the legs not be hindered by the mother. If the thermostat attachment however, it must be installed in such a way that the front side points downwards in the direction of gravity, then the mother falls down due to gravity up to the thread and thus prevents radial Outward movement of the legs. With other mounting directions the nut must be installed up to the start of the thread be pushed and in the same operation to Engagement with the thread must be turned before a final one Clamping the valve cap on the valve housing can be done. Both make assembly difficult.

Der Erfindung liegt daher die Aufgabe zugrunde, die Montage eines Ventilaufsatzes zu vereinfachen.The invention is therefore based on the object To simplify assembly of a valve cap.

Diese Aufgabe wird bei einem Ventilaufsatz der eingangs genannten Art dadurch gelöst, daß auf der der Stirnseite abgewandten Seite des Gewindes eine Mutterhaltevorrichtung angeordnet ist, an der die Mutter in Axialrichtung festlegbar ist. This task is the beginning of a valve attachment mentioned type in that on the front side opposite side of the thread a nut holder is arranged on the nut in the axial direction is definable.

Bei dieser Lösung wird die Mutter außerhalb des Gewindes so festgehalten, daß sie sich in Axialrichtung nicht mehr bewegen kann, zumindest nicht, solange eine derartige Bewegung unerwünscht ist. Die Festlegung erfolgt selbstverständlich lösbar, so daß die Mutter dann, wenn der Ventilaufsatz auf das Ventilgehäuse aufgeschoben worden ist, auf das Gewinde geschraubt werden kann, um ein Festspännen des Ventilaufsatzes am Ventilgehäuse zu ermöglichen. Die Festlegung der Mutter mit Hilfe der Mutterhaltevorrichtung verhindert einerseits, daß die Mutter unter dem Einfluß der Schwerkraft in Richtung auf das Gewinde rutschen kann, wo sie die radiale Auswärtsbewegung der Beine unterbindet. Sie legt andererseits die Mutter an einer definierten Stelle fest, so daß der nachfolgende Aufschraubvorgang für den Monteur einfacher wird. Darüber hinaus ist die Gefahr von Beschädigungen bei der Montage geringer. Wenn die Mutter zuverlässig so gehalten wird, daß die Beine radial nach außen federn, wenn der Ventilaufsatz auf das Ventilgehäuse aufgeschoben wird, dann entfällt die Gefahr, daß bei einer oft zu beobachtenden Gewaltanwendung Teile beschädigt werden.With this solution, the nut is outside the thread so held that they are in the axial direction can no longer move, at least not as long as one such movement is undesirable. The determination is made of course solvable so that the mother then when the valve cap is pushed onto the valve housing has been screwed onto the thread can to tighten the valve cap on the valve housing to enable. Fixing the mother with Help of the nut holding device prevents on the one hand that the mother in under the influence of gravity Direction on the thread can slip where it is radial Prevents outward movement of the legs. she lays on the other hand the mother at a defined point firmly, so that the subsequent unscrewing process for the Fitter becomes easier. Beyond that is the danger less damage during assembly. If the Mother is reliably held so that the legs are radial spring outwards when the valve cap is on the Valve housing is pushed on, then there is no risk of that with an often observed use of force Parts are damaged.

In einer vorteilhaften Ausgestaltung ist vorgesehen, daß die Mutterhaltevorrichtung axial so in bezug auf das Gewinde angeordnet ist, daß sich die festgelegte Mutter axial vollständig außerhalb des Gewindes befindet. Damit ist sichergestellt, daß durch den Eingriff zwischen Mutter und Gewinde keine Behinderung der Bewegung der Beine erfolgt. Andererseits kann das Gewinde axial lang genug gemacht werden, so daß die Mutter im aufgeschraubten Zustand die Haltefunktion zuverlässig erfüllen kann. Wenn die Mutter aufgeschraubt ist, soll nämlich eine radiale Auswärtsbewegung der Beine zuverlässig verhindert werden können. In an advantageous embodiment, that the nut holder is axially so related the thread is arranged so that the set The nut is axially completely outside the thread. This ensures that the intervention no hindrance to movement between nut and thread of legs. On the other hand, the thread be made axially long enough so that the nut in screwed on the holding function reliably can meet. If the nut is screwed on, should namely reliable radial outward movement of the legs can be prevented.

Vorzugsweise weisen die Mutter und die Beine ein radiales Spiel relativ zueinander auf, wenn die Mutter in der Mutterhaltevorrichtung festgelegt ist. Die Mutter wird also nicht nur axial nach hinten, d.h. von der Stirnseite weg, verschoben. Dies würde es lediglich dem nicht von der Mutter abgedeckten Bereich der Beine erlauben, sich radial nach außen zu bewegen. Man läßt vielmehr ein Spiel zwischen den Beinen und der Mutter auch in dem Bereich zu, den die Mutter abdeckt. Damit wird die freie Länge der Beine, d.h. der Bereich der Beine, der an der Bewegung teilnehmen kann, vergrößert und die Belastung verringert.The nut and the legs preferably have a radial one Play relative to each other when the mother is in the nut holding device is fixed. The mother is not only axially backwards, i.e. of the Face away, postponed. It would only do that do not allow the area of the legs covered by the mother, to move radially outward. You leave rather a game between the legs and the mother also in the area covered by the mother. In order to the free length of the legs, i.e. the area of Legs that can participate in the movement are enlarged and reduces the burden.

Vorzugsweise ist die Verbindung der Beine mit dem Träger im Bereich der Mutterhaltevorrichtung angeordnet. Anders ausgedrückt: Die Schlitze, die zwischen den Beinen angeordnet sind und von der Stirnseite ausgehen, enden im Bereich der Mutterhaltevorrichtung. Damit wird der Aufhängepunkt der Beine, d.h. der Punkt, von dem aus eine Bewegung beginnen kann, in den Bereich der Mutterhaltevorrichtung verlegt. Dies erlaubt eine relativ große Federlänge.Preferably, the connection of the legs to the carrier arranged in the area of the nut holding device. In other words: the slits between the legs are arranged and start from the front, ends in the area of the nut holder. So that will the suspension point of the legs, i.e. the point from which from a movement can begin in the area of Nut holding device relocated. This allows a relative large feather length.

Mit Vorteil ist die Mutterhaltevorrichtung durch mindestens einen Vorsprung gebildet, der in das Innengewinde der Mutter eingreift. Dies ist eine sehr einfache Ausgestaltung einer Haltevorrichtung. Wenn das Innengewinde der Mutter und der Vorsprung in Eingriff stehen, ist eine axiale Bewegung der Mutter zunächst einmal unterbunden.The nut holding device is advantageous by at least formed a projection into the internal thread the mother intervenes. This is a very simple design a holding device. If the internal thread the mother and the tab are engaged axial movement of the nut is initially prevented.

Vorzugsweise ist der Vorsprung hierbei als Außengewinde ausgebildet. Das Befestigen der Mutter am Vorsprung beziehungsweise das Lösen der Mutter vom Vorsprung kann dann durch eine einfache Drehbewegung der Mutter erfolgen.The projection is preferably an external thread educated. Attaching the nut to the ledge respectively loosening the nut from the tab then done by simply turning the nut.

Hierbei ist bevorzugt, daß das Außengewinde auf vorbestimmte Bereiche in Umfangsrichtung beschränkt ist. Damit entsteht nur eine geringe Reibung zwischen der Mutter und dem Gewinde, weil die Reibung auf relativ kleine Flächenbereiche beschränkt ist. Dies erleichtert insbesondere das Lösen der Mutter von der Mutterhaltevorrichtung. Gleichzeitig ist bei einem Außengewinde auch eine Führung der Mutter gegeben, wenn sie aus der Mutterhaltevorrichtung gelöst wird. Sie wird nämlich automatisch in Richtung auf das Gewinde vorgeschoben, so daß der Monteur praktisch lediglich eine Drehbewegung machen muß, die sich nach dem Lösen der Mutter von der Mutterhaltevorrichtung in die Festschraubbewegung fortsetzt. Allerdings ist die Lösebewegung hier mit einem geringeren Kraftaufwand verbunden als die Bewegung, die zum Festschrauben erforderlich ist.It is preferred that the external thread to predetermined Areas are limited in the circumferential direction. In order to there is little friction between the nut and the thread because the friction on relatively small Area areas is limited. This makes it easier especially loosening the nut from the nut holder. At the same time with an external thread also given a lead to the mother when she leaves the Mother holding device is released. Because it will automatically advanced towards the thread, so that the fitter practically only a rotary movement who has to do after loosening the mother from the nut holding device in the tightening movement continues. However, the release movement here is with one less effort than the movement, which is necessary for screwing down.

Vorzugsweise sind die Bereiche hierbei den Rändern der Beine in Umfangsrichtung benachbart angeordnet. Dies trägt zu einer Vergrößerung der Stabilität der Beine bei. Außerdem wird die Mutter dann an jedem Bein zuverlässig abgestützt.The regions are preferably the edges of the Legs adjacent in the circumferential direction. This contributes to an increase in the stability of the legs at. In addition, the mother then becomes reliable on every leg supported.

Vorzugsweise weist das Außengewinde einen gegenüber dem Innengewinde der Mutter verminderten Durchmesser auf. Beispielsweise kann man die Mutter mit einem Gewinde M33 versehen und das Außengewinde als Gewinde M32 oder M31 ausbilden. Damit stellt man zum einen sicher, daß ein Spiel zwischen der Mutter und den Beinen im Bereich der Mutterhaltevorrichtung existiert. Zum anderen wird die Drehbewegung der Mutter auf dem Gewinde ohne größeren Kraftaufwand durchführbar. Man kann die Mutter praktisch "mit einem Finger" drehen, bis sie auf das Gewinde trifft. Dann ist in vielen Fällen zumindest zum Festziehen ein Werkzeug erforderlich.Preferably, the external thread has one opposite The internal thread of the nut has a reduced diameter. For example, the nut can be threaded M33 and the external thread as thread M32 or Train M31. On the one hand, this ensures that a game between the mother and the legs in the area the mother holding device exists. On the other hand the rotation of the nut on the thread without major Force can be applied. You can be the mother practically turn "with one finger" until it clicks on the Thread meets. Then in many cases at least Tighten a tool.

The invention is described below with reference to preferred embodiments in conjunction with the drawing. In it show:
Fig. 1
a valve attachment in front of a valve housing and
Fig. 2
different sectional views through the valve attachment.

Ein Ventilaufsatz 1, der auf ein Ventilgehäuse 2 eines Heizkörperventils aufgesetzt werden soll, weist mehrere, im vorliegenden Ausführungsbeispiel vier, Beine 3 auf, die durch Schlitze 4 voneinander getrennt sind. Die Beine 3 umschließen in Umfangsrichtung einen Aufnahmeraum 5, in den das Ventilgehäuse 2 hineinpaßt, wenn der Ventilaufsatz 1 am Ventilgehäuse 2 montiert ist. Hierzu ist der Aufnahmeraum 5 an seiner Stirnseite 6 offen. An dem der Stirnseite abgewandten Ende sind die Beine 3 mit einem Träger 7 verbunden, an dem ein Thermostataufsatz 8 befestigt ist. Die Beine 3 weisen auf ihrer radialen Innenseite Vorsprünge 9 auf, die nach der Montage des Ventilaufsatzes 1 am Ventilgehäuse 2 hinter einem entsprechenden Gegenvorsprung 10 in einer Nut 11 zu liegen kommen. Damit dies möglich ist, müssen die Beine 3 in der Lage sein, beim Montieren radial so weit nach außen bewegt zu werden, daß der Vorsprung 9 über den Vorsprung 10 bewegt werden kann und dann in der Nut 11 einrastet. Umgekehrt muß nach der Montage sichergestellt werden, daß eine derartige Bewegung nicht mehr möglich ist. A valve cap 1, which on a valve housing 2 a Radiator valve to be placed has several four, legs 3 in the present exemplary embodiment on, which are separated by slots 4. The legs 3 enclose a receiving space in the circumferential direction 5, into which the valve housing 2 fits, when the valve cap 1 is mounted on the valve housing 2 is. For this purpose, the receiving space 5 is on its end face 6 open. At the end facing away from the front the legs 3 connected to a support 7, on the one Thermostat attachment 8 is attached. The legs 3 point on their radial inside projections 9 on the after mounting the valve cap 1 on the valve housing 2 behind a corresponding counter projection 10 in one Nut 11 come to rest. To make this possible the legs 3 must be able to radially when mounting to be moved out so far that the projection 9 can be moved over the projection 10 and then snaps into the groove 11. Conversely, after the Assembly ensure that such movement is no longer possible.

Um die Bewegung zu verhindern, ist auf der radialen Außenseite der Beine 3 ein Gewinde 12 vorgesehen. Im Bereich der Stirnseite 6 wird das Gewinde durch einen Vorsprung 13 abgeschlossen, der verhindert, daß eine Mutter 14 in Richtung der Stirnseite 6 aus dem Gewinde 12 herausgeschraubt wird. Die Mutter 14 weist ein Innengewinde 15 auf, das den gleichen Durchmesser wie das Gewinde 12 hat. Beispielsweise sind beide Gewinde als M33 ausgeführt.To prevent the movement is on the radial outside the legs 3 are provided with a thread 12. In the area the end face 6 is the thread by a Protrusion 13 completed, which prevents a Nut 14 in the direction of the end face 6 from the thread 12 is unscrewed. The nut 14 has an internal thread 15 on the same diameter as that Has thread 12. For example, both threads are as M33 executed.

Auf der dem Vorsprung 13 gegenüberliegenden Seite des Gewindes 12 schließt sich an das Gewinde 12 ein weiteres Außengewinde 16 an, das allerdings einen verminderten Durchmesser hat. Dieses Außengewinde 16 ist beispielsweise mit der Bemaßung M32 ausgeführt. Dementsprechend existiert auch dann, wenn die Mutter 14 auf dieses Außengewinde 16 geschraubt ist, ein kleines radiales Spiel zwischen der Mutter 14 und den Beinen 3. Die Schlitze 4 enden übrigens im Bereich dieses Außengewindes 16.On the opposite side of the projection 13 Thread 12 connects to thread 12 another External thread 16, but this is reduced Diameter. This external thread 16 is for example with dimension M32. Accordingly exists even if the mother 14 on this external thread 16 is screwed, a small radial Game between the mother 14 and the legs 3. The slots 4 also end in the area of this external thread 16th

Das Außengewinde 16 dient als Mutterhaltevorrichtung. Die Mutter 14 wird vor der Montage des Ventilaufsatzes 1 an dem Ventilgehäuse 2 vom Gewinde 12 ab und auf das Außengewinde 16 aufgeschraubt. Von dort kann sie ohne Einwirkung von außen nicht mehr auf das Gewinde 12 gelangen. Sie kann also die Aufspreizung der Beine 12 nicht verhindern, unabhängig davon, in welcher Lage der Ventilaufsatz 1 gehalten wird. Aufgrund des Spieles zwischen der Mutter 14 und den Beinen 3 ist eine Aufspreizung, d.h. eine radiale Auswärtsbewegung der Beine 3, ohne weiteres möglich. Diese Bewegung wird durch die Mutter 14 nicht behindert. Hierbei steht nicht nur der Bereich der Beine 3 zwischen Mutter 14 und Stirnseite 6 für die Bewegung zur Verfügung, sondern die gesamte Länge der Beine 3.The external thread 16 serves as a nut holding device. The nut 14 is before assembly of the valve cap 1 on the valve housing 2 from the thread 12 and on External thread 16 screwed on. From there it can be without No more external influence on the thread 12. So you can spread the legs 12th not prevent, regardless of the position of the Valve attachment 1 is held. Because of the game between the mother 14 and the legs 3 is one Spreading, i.e. a radial outward movement of the Legs 3, easily possible. This movement will not hindered by the mother 14. It says not just the area of legs 3 between mother 14 and face 6 are available for movement, but the entire length of the legs 3.

Das Außengewinde 16 bildet im Grunde einen Vorsprung, der mit dem Innengewinde 15 der Mutter 14 in Eingriff steht und hierdurch eine axiale Bewegung der Mutter 14 in Richtung auf die Stirnseite 6 hin verhindert. Dadurch, daß dieser Vorsprung aber als Gewinde ausgebildet ist, läßt sich die Mutter 14 mit relativ einfachen Bewegungen in Richtung auf das Gewinde 12 hin transportieren. Der Monteur muß die Mutter 14 lediglich drehen. Dabei ist diese Drehung aufgrund der lockeren Passung mit relativ wenig Kraft durchzuführen. Das Außengewinde 16 geht in das Innengewinde 12 über, so daß die Mutter 14 bei der Bewegung gleich richtig geführt wird.The external thread 16 basically forms a projection, which engages with the internal thread 15 of the nut 14 stands and thereby an axial movement of the nut 14th prevented in the direction of the end face 6. Thereby, that this projection is formed as a thread is, the mother 14 can be done with relatively simple Transport movements in the direction of the thread 12. The fitter only has to turn the nut 14. This twist is due to the loose fit perform with relatively little force. The external thread 16 passes into the internal thread 12 so that the mother 14 is correctly guided during the movement.

Wie aus Fig. 2 hervorgeht, gibt es für die Ausbildung des Außengewindes mehrere Möglichkeiten.As is apparent from Fig. 2, there is for training of the external thread several options.

Hier zeigt Fig. 2a noch einmal einen Schnitt durch den Ventilaufsatz 1 im Bereich seiner Beine 3. Die Fig. 2b und 2c stellen Schnitte entlang der Linie B-B dar, also schnitte durch das Außengewinde 16. Fig. 2d stellt einen Schnitt A-A, also einen Schnitt im Bereich des Gewindes 12, dar.2a shows a section through the Valve attachment 1 in the area of his legs 3. Fig. 2b and 2c represent sections along the line B-B, ie cuts through the external thread 16. Fig. 2d represents one Section A-A, i.e. a cut in the area of the thread 12.

Das Außengewinde 16 ist bei der Ausgestaltung nach Fig. 2b auf relativ schmale Bereiche in Umfangsrichtung begrenzt. Dazwischen gibt es Lücken 17, die frei sind. Hier gleitet die Mutter 14 einfach auf der bloßen Außenfläche der Beine 3. Die Breite der Gewindeabschnitte kann relativ schmal gewählt werden.The external thread 16 is in the embodiment according to FIG. 2b limited to relatively narrow areas in the circumferential direction. In between there are gaps 17 that are free. Here the nut 14 simply slides on the bare outer surface of legs 3. The width of the thread sections can be chosen relatively narrow.

Fig. 2c zeigt, daß das Außengewinde 16 auch über den vollen Umfang der Beine 3 geführt werden kann. In beiden Fällen ist das Außengewinde 16 als M32-Gewinde ausgeführt.Fig. 2c shows that the external thread 16 also over the full circumference of the legs 3 can be performed. In both In some cases, the external thread 16 is designed as an M32 thread.

Demgegenüber ist das Gewinde 12, das in Fig. 2d dargestellt ist, als M33-Gewinde ausgeführt, genau wie das Innengewinde 15 der Mutter 14.In contrast, the thread 12 is shown in Fig. 2d is designed as an M33 thread, just like that Internal thread 15 of the nut 14.

Man kann in einer etwas verschlechterten Ausführungsform das Gewinde auch über die gesamte axiale Erstrekkung der Beine 3 durchgehen lassen, ohne daß eine Durchmesserverringerung auftritt. In diesem Fall betrachtet man als Gewinde 12 den Bereich, der bei montiertem Ventilaufsatz 1 von der Mutter 14 abgedeckt ist.One can in a somewhat worse embodiment the thread also over the entire axial extent let the legs 3 pass through without one Diameter reduction occurs. Considered in this case one as the thread 12 the area that with assembled Valve cap 1 covered by the nut 14 is.

Von der dargestellten Ausführungsform kann in vielerlei Hinsicht abgewichen werden. Anstelle des Außengewindes 16 können auch andere Mittel zum Festhalten der Mutter 14 verwendet werden, beispielsweise eine Rastverbindung, bei der ein gewisser axialer Zug erforderlich, um die Mutter wieder zu lösen. Denkbar wäre auch eine konische Aufweitung des Trägers 7 am Übergang zu den Beinen 3, auf die die Mutter 14 aufgeschoben werden kann und dort unter Reibkraft festhält. Schließlich kann die Mutter 14 auch an ihrer radialen Außenseite mit geeigneten Mitteln festgehalten werden.The illustrated embodiment can be used in many ways Terms are deviated. Instead of the external thread 16 can also use other means to hold the mother 14 are used, for example a snap-in connection, where some axial pull is required to to loosen the mother again. A conical one would also be conceivable Widening of the carrier 7 at the transition to the legs 3, on which the nut 14 can be pushed and holds there under frictional force. Finally, the Nut 14 also on its radial outside with suitable Funds are held.
