Description

Die Erfindung betrifft eine Vorrichtung zum Anschluß eines Heizkörperventits, insbesondere Thermostatventils, an einen Heizkörper, mit einer Anschlußtülle, die an einem Ende einen Stützflansch mit Überwurfmutter zum Anschluß an einen Stutzen des Heizkörperventils und im Bereich des anderen Endes einen in eine Gewindebohrung des Heizkörpers eindrehbaren Heizkörperanschlußstopfen mit einem Radialflansch aufweist, wobei der Radialflansch eine Dichtungsfläche für den Heizkörper besitzt und der Heizkörperanschlußstopfen abgedichtet sowie drehbar und längs verschieblich auf der Anschlußtülle angeordnet ist sowie ein Profil für den Ansatz eines Werkzeuges aufweist.The invention relates to a device for connecting a radiator valve, in particular a thermostatic valve, to a radiator, with a connecting grommet having a support flange with a union nut at one end for connection to a connecting piece of the radiator valve and, in the region of the other end, a radiator connecting plug which can be screwed into a threaded hole in the radiator having a radial flange, the radial flange having a sealing surface for the radiator and the radiator connector plug being sealed and rotatably and longitudinally displaceable on the connecting sleeve and having a profile for the attachment of a tool.

Bei der Erstmontage einer Heizungsanlage wird in eine zugeordnete Gewindebohrung des ersten Gliedes eines Heizkörpers (Radiator) ein Heizkörperanschtußstopfen eingedreht, der mit einer Anschlußtülle fest verbunden ist. Am freien Ende der Anschlußtülle wird mit Hilfe der Überwurfmutter das Heizkörperventil befestigt. Die zum Heizkörperventil führende Anschlußleitung wird so abgelängt und mit einem Außengewinde versehen, daß ein zugeordneter Anschiußstutzen des Heizkörperventils auf das Gewinde aufgedreht werden kann.When installing a heating system for the first time, a radiator connection plug is screwed into an associated threaded hole in the first element of a radiator (radiator), which is firmly connected to a connecting grommet. The radiator valve is attached to the free end of the connection grommet using the union nut. The connecting line leading to the radiator valve is cut to length and provided with an external thread so that an associated connecting piece of the radiator valve can be screwed onto the thread.

Im Zuge von Energiesparmaßnahmen werden in zunehmendem Maße die bisher üblichen Heizkörperventile, die einfache Handregulierventiie waren, durch andere Ventile, insbesondere durch Thermostatventile, ersetzt. Diese Thermostatventile haben aber meistens eine größere Baulänge als die bisher eingesetzten Heizkörperventile. Bevor deshalb ein Thermostatventil anstelle eines vorhandenen Ventils eingesetzt werden kann, muß deswegen entweder die Anschlußleitung verkürzt werden oder der Heizkörper versetzt werden. Beides erfordert einen erheblichen Arbeits- und Zeitaufwand. Das Verkürzen der Anschlußleitungen läßt sich meist nur mit Hilfe autogener Schweißung durchführen. Zusätzlich muß das neue Ende der Anschlußleitung mit einem Gewinde versehen werden. Das sind sehr mühsame Arbeiten, die noch dadurch erschwert werden, daß Heizkörper sich in der Regel in Heizkörpernischen befinden, die schwer zugänglich sind. In einigen Fällen sind auch die freien, zur Verfügung stehenden Längen der Anschlußleitungen begrenzt. Ähnliches gilt auch für das Versetzen der Heizkörper selbst.In the course of energy saving measures, the previously common radiator valves, which were simple manual regulating valves, are increasingly being replaced by other valves, in particular by thermostatic valves. However, these thermostatic valves usually have a greater overall length than the radiator valves used previously. Therefore, before a thermostatic valve can be used instead of an existing valve, either the connection line must be shortened or the radiator must be moved. Both require a considerable amount of work and time. The shortening of the connecting lines can usually only be carried out with the help of autogenous welding. In addition, the new end of the connection line must be threaded. This is very tedious work, which is made even more difficult by the fact that radiators are usually located in radiator recesses that are difficult to access. In some cases, the free, available lengths of the connecting lines are also limited. The same applies to moving the radiators themselves.

Bei einer aus der DE-A-2 025 034 bekannten Vorrichtung der eingangs beschriebenen Gattung ist die Anschlußtülle relativ zum Heizkörperanschlußstopfen längsverschieblich. Es wird der bei der Erstausrüstung in den Heizkörper eingesetzte Heizkörperanschlußstopfen verwendet und in sein Innengewinde ein mit Außengewinde versehener Axialflansch einer zweiteiligen Stopfbuchse eingedreht. Die Stopfbuchse dichtet gegen die Anschlußtülle, die jedoch einen geringeren Durchmesser aufweisen muß als die ursprünglich verwendete Anschlußtülle. Die Stopfbuchse besteht aus zwei verhältnismäßig komplizierten Teilen, die eine aufwendige Bearbeitung erfordern. Die gesamte Vorrichtung besitzt eine verhältnismäßig große axiale Länge. Wenn man diese Vorrichtung zum Anschluß eines Thermostatventils benutzen will, welches in der Regel eine größere axiale Länge als das bisher verwendete Heizkörperventil besitzt, dann geht das nur, wenn zwischen dem Ende der Anschlußleitung einerseits und dem Ende der Stopfbuchse andererseits hinreichend Platz zur Verfügung steht. Meist ist aber im Zuge der Erstmontage der Heizungsanlage die Anschlußleitung so abgelängt, daß das seinerzeit verwendete Heizlörperventil eingesetzt werden konnte. Da die bekannte Vorrichtung zusätzliche axiale Länge beansprucht, können längere Thermostatventile nur dann eingesetzt werden, wenn die Anschlußleitung entsprechend verkürzt wird.In a device of the type described in the introduction, which is known from DE-A-2 025 034, the connecting grommet is longitudinally displaceable relative to the radiator connecting plug. The radiator connection plug used in the original equipment is used and an axial flange of a two-part stuffing box provided with an external thread is screwed into its internal thread. The stuffing box seals against the connection sleeve, which, however, must have a smaller diameter than the connection sleeve originally used. The stuffing box consists of two relatively complicated parts that require complex processing. The entire device has a relatively large axial length. If you want to use this device to connect a thermostatic valve, which usually has a greater axial length than the radiator valve previously used, this is only possible if there is sufficient space between the end of the connecting line on the one hand and the end of the stuffing box on the other. Usually, however, in the course of the initial installation of the heating system, the connecting line is cut to length so that the radiator valve used at that time could be used. Since the known device requires additional axial length, longer thermostatic valves can only be used if the connecting line is shortened accordingly.

Bei einer lösbaren Flanschverbindung (DE-A-1 925 477) ist es bekannt, einen Rohrabschnitt mit inneren Umfangsnuten zur Aufnahme von Dichtungsringen zu versehen, in denen ein anderer Rohrabschnitt geführt wird. Das hat jedoch die Probleme beim Ersetzen von herkömmlichen Heizkörperventilen durch andere Ventile, insbesondere Thermostatventile, nicht beeinflussen können.In a releasable flange connection (DE-A-1 925 477) it is known to provide a pipe section with inner circumferential grooves for receiving sealing rings, in which another pipe section is guided. However, this has not been able to affect the problems of replacing conventional radiator valves with other valves, particularly thermostatic valves.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Gattung konstruktiv einfacher und platzsparend auszubilden.The invention is based on the object of designing a device of the type described at the outset in a structurally simpler and space-saving manner.

Diese Aufgabe wird dadurch gelöst, daß der Anschlußstopfen an seiner inneren Umfangsfläche eine Umfangsnut für einen mit der Anschlußtülle dichtenden Dichtungsring aufweist und daß das Profil für den Ansatz des Werkzeuges durch den Außenumfang des Radialflansches gebildet ist und sich über dessen ganze Breite bis zu seiner Dichtungsfläche erstreckt.This object is achieved in that the connecting plug has on its inner circumferential surface a circumferential groove for a sealing ring sealing with the connecting sleeve and that the profile for the attachment of the tool is formed by the outer circumference of the radial flange and extends over its entire width to its sealing surface .

Bei Einsatz der erfindungsgemäßen Vorrichtung treten die eingangs erläuterten Schwierigkeiten nicht mehr auf. Die Halterungen des Heizkörpers brauchen nicht gelöst zu werden, auch die Verschraubung am Rücklauf bleibt angezogen. Mit einer Metallsäge oder einer kleinen Trennscheibe wird lediglich die Anschlußtülle der vorhandenen Vorrichtung durchtrennt und nach Lösen der Überwurfmutter entfernt. Nach dem Entfernen des eingebauten Heizkörperventils wird auch der vorhandene Heizkörperanschlußstopfen mit dem Rest der Anschlußtülle aus dem ersten Glied des Heizkörpers herausgedreht. Dann wird der Heizkörperanschlußstopfen der erfindungsgemäßen Vorrichtung in die zugeordnete Öffnung des ersten Gliedes des Heizkörpers eingedreht, und wird die Anschlußtülle so weit in den Heizkörperanschlußstopfen bzw. in den Heizkörper eingeschoben, daß das neue Ventil, insbesondere Thermostatventil, ohne Schwierigkeiten an das freie Ende der Anschlußleitung angeschlossen werden kann. Dann wird die Anschlußtülle in Richtung auf das neue Ventil vorgezogen, bis ihr Stützflansch gegen den zugeordneten Anschlußstutzen des neuen Ventils stößt, und wird die Überwurfmutter auf diesen Anschlußstutzen aufgedreht. Diese Arbeit kann von nur einem Monteur durchgeführt werden, der in der Regel nicht mehr als 15 Minuten dafür benötigt. Es entstehen zwar zusätzliche Kosten für die Vorrichtung selbst, diese Kosten werden aber durch Arbeitsersparnis mehrfach eingespart. - Das ist möglich, weil die Länge des Heizkörperanschlußstopfens bzw. seine über das Ende des Heizkörpers vorstehende axiale Länge geringer ist als die eines herkömmlichen Heizkörperanschlußstopfens und weil der am Heizkörper anliegende Radialflansch an seinem Außenumfang das Profil für den Ansatz eines Werkzeuges trägt.When using the device according to the invention, the difficulties explained at the beginning no longer occur. The radiator brackets do not need to be loosened, the screw connection on the return remains tightened. With a hacksaw or a small cutting disc, only the connection nozzle of the existing device is cut and removed after loosening the union nut. After removing the built-in radiator valve, the existing radiator connection plug with the rest of the connection nozzle is unscrewed from the first element of the radiator. Then the radiator connector plug of the device according to the invention is screwed into the associated opening of the first member of the radiator, and the connecting sleeve is inserted into the radiator connector plug or into the radiator to such an extent that the new valve, in particular a thermostatic valve, is easily connected to the free end of the connecting line can be connected. Then the connection grommet is directed towards the new valve preferred until its support flange abuts the associated connecting piece of the new valve, and the union nut is screwed onto this connecting piece. This work can be carried out by only one technician, who usually does not need more than 15 minutes to do it. There are additional costs for the device itself, but these costs are saved several times by labor savings. - This is possible because the length of the radiator connection plug or its axial length protruding over the end of the radiator is less than that of a conventional radiator connection plug and because the radial flange adjacent to the radiator bears the profile for the attachment of a tool on its outer circumference.

Die Erfindung hat erkannt, daß nicht nur die axiale Länge des Heizkörperanschlußstopfens dadurch reduziert werden kann, daß der Radialflansch an seinem Außenumfang mit dem Profil für den Ansatz eines Werkzeuges versehen ist, sondern daß auch die Dichtung in den Radialflansch bzw. in den Heizkörperanschlußstopfen selbst integriert werden kann. Der Heizkörperanschlußstopfen bzw. sein Radialflansch übernimmt damit eine Doppelfunktion.The invention has recognized that not only the axial length of the radiator connection plug can be reduced in that the radial flange is provided on its outer circumference with the profile for the attachment of a tool, but also that the seal is integrated into the radial flange or into the radiator connection plug itself can be. The radiator connector plug or its radial flange thus takes on a double function.

Da die Drücke in Heizungsanlagen vergleichsweise gering sind, kann die Dichtung zwischen Heizkörperanschlußstopfen und Anschlußtülle auch einfach ausgebildet sein. Insbesondere kann die Dichtung ein O-Ring sein.Since the pressures in heating systems are comparatively low, the seal between the radiator connection plug and the connection nozzle can also be simple. In particular, the seal can be an O-ring.

Um bei Transport und Montage zu verhindern, daß die Anschlußtülle aus dem Heizkörperanschlußstopfen herausgleitet, empfiehlt es sich, die Anschlußtülle gegen Herausgleiten aus dem Heizkörperanschlußstopfen zu sichern. Das kann im einfachsten Fall dadurch geschehen, daß in radialen Bohrungen der Anschlußtülle ein Sicherungsstift gehalten ist.In order to prevent the connecting sleeve from sliding out of the radiator connecting plug during transport and assembly, it is recommended to secure the connecting sleeve against sliding out of the radiator connecting plug. In the simplest case, this can be done by holding a locking pin in radial bores of the connecting sleeve.

Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert; es zeigt

  • Fig. 1 eine Seitenansicht einer Vorrichtung zum Anschluß eines Thermostatventils an einen Heizkörper,
  • Fig. 2 einen Längsschnitt durch den Gegenstand nach Fig. 1.
In the following an embodiment of the invention shown in the drawing is explained; it shows
  • 1 is a side view of a device for connecting a thermostatic valve to a radiator,
  • FIG. 2 shows a longitudinal section through the object according to FIG. 1.

Die dargestellte Vorrichtung wird eingesetzt, wenn im Zuge von Energiesparmaßnahmen die vorhandenen Heizkörperventile an Heizkörpern durch Thermostatventile ersetzt werden sollen. Die Vorrichtung besteht aus einem Heizkörperanschlußstopfen 1 mit einem Außengewinde 2 und einem das Außengewinde 2 überragenden Radialflansch 3. Der Heizkörperanschlußstopfen 1 wird in üblicher Weise in eine zugeordnete Gewindeöffnung des letzten Gliedes eines nicht dargestellten Heizkörpers (Radiator) eingedreht. Der Heizkörperanschlußstopfen 1 wiest eine Stufenbohrung 4 auf, deren engerer Teil 5 sich im Bereich des Radialflansches 3 befindet und in axialer Richtung etwa die doppelte Länge des Radialflansches 3 besitzt. An der inneren Umfangsfläche des engeren Teils 5 ist eine Umfangsnut 6 für einen darin gehaltenen Dichtungsring 7 angeordnet. Bei dem Dichtungsring 7 handelt es sich um einen O-Ring.The device shown is used when the existing radiator valves on radiators are to be replaced by thermostatic valves in the course of energy-saving measures. The device consists of a radiator connection plug 1 with an external thread 2 and a radial flange 3 projecting beyond the external thread 2. The radiator connection plug 1 is screwed into an associated threaded opening of the last link of a radiator (not shown) (radiator) in the usual way. The radiator connection plug 1 has a stepped bore 4, the narrower part 5 of which is located in the region of the radial flange 3 and has approximately twice the length of the radial flange 3 in the axial direction. A circumferential groove 6 for a sealing ring 7 held therein is arranged on the inner circumferential surface of the narrower part 5. The sealing ring 7 is an O-ring.

Im engeren Teil 5 der Stufenbohrung 4 ist mit geringem Spiel eine Anschlußtülle 8 geführt, die im Heizkörperanschlußstopfen 1 um die Längsachse drehbar und in Richtung der Längsachse verschieblich ist. Die Anschlußtülle 8 weist auf der Gewindeseite des Heizkörperanschlußstopfens 1 einander gegenüberliegende radiale Bohrungen 9, 10 auf, in denen ein Sicherungsstift 11 gehalten ist. Die Abmessungen des Sicherungsstiftes 11 einerseits und diejenigen des größeren Teils der Stufenbohrung 4 andererseits sind so gewählt, daß die Anschlußtülle 8 relativ zum Heizkörperanschlußstopfen 1 so weit verschoben werden kann, daß der Sicherungsstift 11 an der Stufe 12 der Stufenbohrung 4 anliegt.In the narrower part 5 of the stepped bore 4, a connecting sleeve 8 is guided with little play, which is rotatable about the longitudinal axis in the radiator connecting plug 1 and displaceable in the direction of the longitudinal axis. The connecting sleeve 8 has on the threaded side of the radiator connector plug 1 opposite radial bores 9, 10, in which a locking pin 11 is held. The dimensions of the locking pin 11, on the one hand, and those of the larger part of the stepped bore 4, on the other hand, are selected so that the connecting sleeve 8 can be displaced relative to the radiator connecting plug 1 so far that the locking pin 11 rests on the step 12 of the stepped bore 4.

An das andere Ende der Anschlußtülle 8 ist ein Stützflansch 13 angeformt, der von einem nach innen gerichteten Flansch 14 einer Überwurfmutter 15 mit Innengewinde 16 hinterfaßt wird. Der Außenumfang sowohl der Überwurfmutter 15 als auch des Radialflansches 3 sind für den Ansatz von zugeordneten Werkzeugen in üblicher Weise profiliert, z. B. als Sechskant ausgebildet.At the other end of the connecting sleeve 8, a support flange 13 is formed, which is gripped by an inwardly directed flange 14 of a union nut 15 with an internal thread 16. The outer circumference of both the union nut 15 and the radial flange 3 are profiled for the approach of associated tools in the usual way, for. B. designed as a hexagon.

Bei Verwendung der dargestellten Vorrichtung geht man wie folgt vor: Ein vorhandenes Heizkörperventil an einem Heizkörper soll durch ein Thermostatventil ausgewechselt werden, dessen Baulänge größer ist als diejenige des vorhandenen Heizkörperventils. Nach Demontage des vorhandenen Heizkörperventils wird auch der vorhandene Heizkörperanschlußstopfen mit daran befestigter Anschlußtülle aus dem letzten Glied des Heizkörpers herausgedreht. Dann wird der Heizkörperanschlußstopfen 1 der dargestellten Vorrichtung in die zugeordnete Öffnung des letzten Gliedes des Heizkörpers eingedreht. Die Anschlußtülle 8 wird soweit wie möglich oder soweit wie erforderlich in dem Heizkörperanschlußstopfen 1 eingeschoben. Dann kann das Thermostatventil mit seinem zugeordneten Anschlußstutzen an dem Ende der weiterführenden Anschlußleitung montiert werden. Danach wird die Anschlußtülle 8 so weit aus dem Heizkörperanschlußstopfen 1 herausgezogen, bis ihr Stützflansch 13 am zugeordneten Anschlußstutzen des neuen Thermostatventils anliegt. Nach dem Aufdrehen der Überwurfmutter 15 auf diesen Anschlußstutzen ist die Heizung wieder betriebsbereit.When using the device shown, proceed as follows: An existing radiator valve on a radiator is to be replaced by a thermostatic valve, the length of which is greater than that of the existing radiator valve. After dismantling the existing radiator valve, the existing radiator connection plug with the attached connection nozzle is unscrewed from the last link of the radiator. Then the radiator plug 1 of the device shown is screwed into the associated opening of the last link of the radiator. The connection sleeve 8 is inserted as far as possible or as far as necessary in the radiator connection plug 1. Then the thermostatic valve with its associated connection piece can be mounted at the end of the connecting line. Thereafter, the connecting sleeve 8 is pulled out of the radiator connecting plug 1 until its supporting flange 13 abuts the associated connecting piece of the new thermostatic valve. After the union nut 15 has been screwed onto this connecting piece, the heating is ready for operation again.
