- Whether and how many additional basic elements G3 to G9 are added to the standard element formed by basic elements G1 and G2 with the help of screw nipples N depends on the heating power required by the respective radiator.
Abstract
Description
Die Erfindung betrifft einen Heizkörper, insbesondere Rohrradiator, aus mindestens zwei gleichartigen Grundelementen, die seitlich nebeneinander angeordnet und an ihrem nabenartigen Kopf- und Fußbereich unter Ausbildung einer kreisförmigen Überströmöffnung durch Verschweißung oder jeweils einen Nippel flüssigkeits- und gasdicht miteinander verbunden sind, wobei ein Grundelement mit einem Anschlußstutzen für den Heizmittelvorlauf und ein anderes Grundelement mit einem Anschlußstutzen für den Heizmittelrücklauf versehen ist, zumindest die endseitigen Grundelemente im Kopf- und Fußbereich mit einem Innengewinde für einen Verschlußstopfen bzw. ein Ventilgehäuse versehen sind und das mit dem Anschlußstutzen für den Heizmittelvorlauf versehene Grundelement in diesem Zulaufbereich gegenüber dem benachbarten Grundelement abgedichtet und im anderen Nabenbereich mit einer Abdichtung für das Ventilgehäuse versehen ist.The invention relates to a radiator, in particular a tubular radiator, made of at least two identical basic elements, which are arranged laterally next to one another and are connected to one another in a liquid-tight and gas-tight manner at their hub-like head and foot region with the formation of a circular overflow opening by welding or in each case a nipple, one basic element having a connecting piece for the heating medium flow and another basic element is provided with a connecting piece for the heating medium return, at least the end-side basic elements in the head and foot area are provided with an internal thread for a sealing plug or a valve housing and the basic element provided with the connecting piece for the heating medium flow in this inlet area is sealed off from the adjacent base element and is provided in the other hub area with a seal for the valve housing.
Heizkörper der voranstehend beschriebenen Art sind in verschiedenen Ausführungen bekannt. Um zu verhindern, daß das über den Anschlußstutzen des einen Grundelementes dem Heizkörper zugeführte Heizmittel unter Umgehung des Heizkörperventils in das benachbarte Grundelement eintritt, ist das mit dem Anschlußstutzen für den Heizmittelvorlauf versehene Grundelement in diesem Zulaufbereich gegenüber dem benachbarten Grundelement dadurch abgedichtet, daß die Überströmöffnung durch eine Metallscheibe verschlossen ist, die in die Überströmöffnung eingeschweißt wird. Für das Verschließen ist somit ein separater Schweißvorgang erforderlich, der nicht nur einen zusätzlichen Aufwand bedeutet, sondern auch verhältnismäßig schwierig durchzuführen ist, weil er im Inneren des vorzugsweise nabenartigen Fußbereiches ausgeführt werden muß.Radiators of the type described above are known in various designs. In order to prevent the heating medium supplied to the radiator via the connecting piece of the one basic element from entering the adjacent basic element bypassing the radiator valve, the basic element provided with the connecting piece for the heating medium supply is sealed in this inlet area from the neighboring basic element by the overflow opening through a metal disc is closed, which is welded into the overflow opening. A separate welding process is therefore required for the closure, which not only means additional effort, but also is relatively difficult to carry out is because it must be carried out inside the preferably hub-like foot area.
Der Erfindung liegt die Aufgabe zugrunde, den technischen Aufwand für die Abdichtung der benachbarten Grundelemente im Zulaufbereich des Heizmittels zu verringern.The invention has for its object to reduce the technical effort for sealing the adjacent basic elements in the inlet area of the heating medium.
Die Lösung dieser Aufgabenstellung durch die Erfindung ist dadurch gekennzeichnet, daß die kreisförmige Überströmöffnung zwischen dem mit dem Anschlußstutzen für den Heizmittelvorlauf versehenen Grundelement und dem benachbarten Grundelement durch eine Scheibe verschlossen ist, die mittels eines Distanzstückes durch den in das gegenüberliegende Innengewinde eingeschraubten Verschlußstopfen dichtend an den die Überströmöffnung umgebenden Rand angepreßt wird.The solution to this problem by the invention is characterized in that the circular overflow opening between the base element provided with the connecting piece for the heating medium flow and the adjacent base element is closed by a washer which seals by means of a spacer by the sealing plug screwed into the opposite internal thread the edge surrounding the overflow opening is pressed.
Durch diesen erfindungsgemäßen Vorschlag entfällt der bisher erforderliche zusätzliche Schweißvorgang zum Abdichten benachbarter Grundelemente im Zulaufbereich des Heizmittels. Anstelle dieses Schweißvorganges wird bei der Montage des Heizkörpers eine lose Scheibe in das mit dem Anschlußstutzen für den Heizmittelvorlauf versehene Grundelement eingelegt und mittels des zum Verschließen der stirnseitigen Öffnung sowieso notwendigen Verschlußstopfens mit Hilfe eines Distanzstückes derart an den die zu verschließende Überströmöffnung umgebenden Rand angepreßt, daß die im Bereich dieser Überströmöffnung miteinander verschweißten Grundelemente gegeneinander abgedichtet sind. Da der Abdichtvorgang lediglich ein zusätzliches Distanzstück erfordert, das bisher erforderliche Einschweißen einer Scheibe jedoch entbehrlich macht, verringert sich der technische Aufwand gegenüber der bisher bekannten Konstruktion auf etwa 10 %.This proposal according to the invention eliminates the additional welding process previously required for sealing adjacent basic elements in the inflow area of the heating medium. Instead of this welding process, a loose disc is inserted into the base element provided with the connecting piece for the heating medium flow during assembly of the radiator and pressed by means of the sealing plug, which is anyway necessary for closing the front opening, with the aid of a spacer to the edge surrounding the overflow opening to be closed in such a way that the basic elements welded together in the area of this overflow opening are sealed against one another. Since the sealing process only requires an additional spacer, but the welding of a pane that was previously required can be dispensed with, the technical effort is reduced to approximately 10% compared to the previously known construction.
Da auch das in das mit dem Anschlußstutzen für den Heizmittelvorlauf versehene Grundelement einzusetzende Ventilgehäuse gegenüber der kreisförmigen Öffnung im Überströmbereich zwischen diesem Grundelement und dem benachbarten Grundelement abgedichtet werden muß, wird gemäß einem weiteren Merkmal der Erfindung vorgeschlagen, die Abdichtung durch einen Ring vorzunehmen, der durch einen endseitigen Bund des Ventilgehäuses zentriert und dichtend an den die Überströmöffnung umgebenden Rand angepreßt wird.Since the valve housing to be inserted into the base element provided with the connecting piece for the heating medium flow must also be sealed with respect to the circular opening in the overflow area between this base element and the adjacent base element, it is proposed according to a further feature of the invention to carry out the sealing by means of a ring which is formed by an end collar of the valve housing is centered and pressed sealingly against the edge surrounding the overflow opening.
Auf diese Weise entfällt auch ein Schweißvorgang für das Einsetzen einer Büchse im Übergang zwischen dem ersten und zweiten Grundelement. Da der erfindungsgemäße Ring auf einfache Weise durch einen am Ventilgehäuse ausgebildeten Bund einerseits zentriert und andererseits dichtend an den die Überströmöffnung umgebenden Rand zwischen den beiden benachbarten Grundelementen angepreßt werden kann, ergibt sich somit bei der erfindungsgemäßen Ausführung auch insoweit eine erhebliche Reduzierung des Herstellungsaufwandes.In this way, there is also no welding process for inserting a sleeve in the transition between the first and second basic elements. Since the ring according to the invention can be centered on the one hand in a simple manner by a collar formed on the valve housing and, on the other hand, can be pressed sealingly against the edge surrounding the overflow opening between the two adjacent basic elements, the embodiment according to the invention thus also results in a considerable reduction in the manufacturing outlay.
Gemäß einem weiteren Merkmal der Erfindung besteht die Scheibe bzw. der Ring aus dauerelastischem Material, vorzugsweise aus Gummi oder gummiartigem Kunststoff. Das Distanzstück zur Festlegung der Scheibe wird vorzugsweise als Rohr ausgebildet.According to a further feature of the invention, the disk or the ring consists of permanently elastic material, preferably of rubber or rubber-like plastic. The spacer for fixing the disc is preferably designed as a tube.
Um eine zuverlässige Abdichtung des Ventilgehäuses gegenüber der kreisförmigen Öffnung im Überströmbereich zwischen dem mit dem Anschlußstutzen für den Heizmittelvorlauf versehenen Grundelement und dem benachbarten Grundelement zu erzielen, wird bei einer bevorzugten Ausführungsform der Erfindung der endseitige Bund des Ventilgehäuses mit einer kegelförmigen Mantelfläche und einer ringförmigen Übergangsfläche ausgeführt. Die kegelförmige Mantelfläche ergibt hierbei eine zuverlässige Zentrierung, die ringförmige Übergangsfläche eine zuverlässige Anpressung des Ringes an den Rand der Überströmöffnung.In order to achieve a reliable seal of the valve housing with respect to the circular opening in the overflow area between the base element provided with the connecting piece for the heating medium flow and the adjacent base element, in a preferred embodiment of the invention the end collar of the valve housing is designed with a conical outer surface and an annular transition surface . The conical surface provides reliable centering, the annular transition surface reliably presses the ring onto the edge of the overflow opening.
Um unter Verwendung eines Standardelements für den Anschluß des Heizkörpers an die Heizmittelleitungen durch Ansetzen beliebig vieler weiterer Grundelemente Heizkörper unterschiedlicher Wärmeleistung herstellen zu können, wird mit der Erfindung weiterhin vorgeschlagen, das dem mit dem Anschlußstutzen für den Heizmittelvorlauf versehenen Grundelement unmittelbar benachbarte Grundelement mit dem Anschlußstutzen für den Heizmittelrücklauf zu versehen. Hierdurch ergibt sich unabhängig von der jeweiligen Anzahl der Grundelemente des Heizkörpers stets dasselbe Standardelement für den Anschluß des Heizkörpers an die Heizmittelleitungen. Über die Anzahl der zusätzlichen Grundelemente wird die für den jeweiligen Einzelfall benötigte Heizleistung bestimmt. Insgesamt ergibt sich durch diese erfindungsgemäße Weiterbildung eine Reduzierung der Lagerhaltung bei gleichzeitiger Vereinfachung der Herstellung von Heizkörpern mit unterschiedlicher Heizleistung.In order to be able to produce radiators of different heat outputs using a standard element for connecting the radiator to the heating medium lines by attaching any number of further basic elements, the invention further proposes that the basic element directly provided with the connecting piece for the heating medium flow with the connecting piece for to provide the heating medium return. This results in the same standard element for connecting the radiator to the heating medium lines, regardless of the number of basic elements of the radiator. The heating power required for each individual case is determined by the number of additional basic elements. Overall, this development according to the invention results a reduction in inventory while simplifying the manufacture of radiators with different heating capacities.
Sofern die Grundelemente jeweils aus zwei Kopfstücken und mindestens einem Verbindungsrohr bestehen, wird gemäß einem weiteren Merkmal der Erfindung vorgeschlagen, die Grundelemente am Rand ihrer kreisförmigen Überströmöffnungen miteinander zu verschweißen und an der Innenseite ihrer freien Öffnungen jeweils mit einem Gewindering zum Einschrauben eines Ventilgehäuses, eines Verschlußstopfens oder eines Schraubnippels für den Anschluß mindestens eines weiteren Grundelementes zu versehen.If the basic elements each consist of two head pieces and at least one connecting tube, it is proposed according to a further feature of the invention to weld the basic elements together at the edge of their circular overflow openings and on the inside of their free openings each with a threaded ring for screwing in a valve housing, a sealing plug or to provide a screw nipple for the connection of at least one further basic element.
Bei einer bevorzugten Ausführungsform ist das Ventilgehäuse zur Aufnahme des Oberteils eines Thermostatventils ausgebildet.In a preferred embodiment, the valve housing is designed to receive the upper part of a thermostatic valve.
Schließlich wird mit der Erfindung vorgeschlagen, den Anschlußstutzen für den Heizmittelvorlauf bzw. Heizmittelrücklauf als ein mit Innengewinde versehenes, in den Fußbereich des jeweiligen Grundelementes eingeschweißtes Rohrstück auszubilden. Hierdurch ergibt sich eine besonders einfache Ausbildung für den Anschlußstutzen.Finally, it is proposed with the invention to design the connecting piece for the heating medium flow or heating medium return as a pipe piece provided with an internal thread and welded into the foot region of the respective basic element. This results in a particularly simple design for the connecting piece.

Bei dem in den Figuren 1 bis 4 dargestellten Ausführungsbeispiel besteht der Heizkörper aus insgesamt neun Grundelementen G1 bis G9. Jedes Grundelement G1 bis G9 besteht aus zwei Kopfstücken K1 und K2, die beispielsweise jeweils aus zwei Halbschalen hergestellt und miteinander durch zwei Verbindungsrohre V1 und V2 verbunden sind. Hierdurch ergeben sich preiswert herzustellende Grundelemente, wobei die Kopfstücke K1 und K2 selbstverständlich auch nur durch ein oder durch mehr als zwei Verbindungsrohre V1 und V2 miteinander verbunden sein können.In the embodiment shown in Figures 1 to 4, the radiator consists of a total of nine basic elements G1 to G9. Every basic element G1 to G9 consists of two head pieces K1 and K2, each made, for example, of two half-shells and connected to one another by two connecting pipes V1 and V2. This results in basic elements which are inexpensive to produce, the head pieces K1 and K2, of course, also being able to be connected to one another only by one or more than two connecting pipes V1 and V2.
Jedes Grundelement G1 bis G9 hat einen nabenartigen Kopf- und Fußbereich, in dem zwei einander gegenüberliegende kreisförmige Überströmöffnungen U ausgebildet sind. In dem diese Überströmöffnungen U umgebenden Randbereich sind die Grundelemente G1 bis G9 miteinander flüssigkeitsdicht verbunden.Each basic element G1 to G9 has a hub-like head and foot region, in which two opposite circular overflow openings U are formed. In the edge region surrounding these overflow openings U, the basic elements G1 to G9 are connected to one another in a liquid-tight manner.
Diese Verbindung benachbarter Grundelemente G1 bis G9 erfolgt entweder durch unmittelbares Verschweißen der die Überströmöffnungen U umgebenden Ränder oder durch eingeschweißte Gewinderinge R, die mit Hilfe eines mit gegenläufigem Gewinde versehenen Schraubnippel N miteinander verbunden werden. Das unmittelbare Verschweißen benachbarter Grundelemente G1 bis G9 ist in Fig. 3 durch die Schweißnaht S zwischen den Grundelementen G1 und G2 und in Fig. 4 durch die Schweißnaht S zwischen den Grundelementen G3 und G4 dargestellt. Das Einschweißen der Gewinderinge R ist bezüglich der Grundelemente G2 und G3 sowohl in Fig. 3 als auch in Fig. 4 dargestellt.This connection of adjacent basic elements G1 to G9 takes place either by direct welding of the edges surrounding the overflow openings U or by welded-in threaded rings R which are connected to one another with the aid of a screw nipple N provided with an opposing thread. The direct welding of adjacent basic elements G1 to G9 is shown in FIG. 3 by the weld seam S between the basic elements G1 and G2 and in FIG. 4 by the weld seam S between the basic elements G3 and G4. The welding of the threaded rings R is shown with respect to the basic elements G2 and G3 both in FIG. 3 and in FIG. 4.
Um unabhängig von der Anzahl der Grundelemente ein Standardelement für den Anschluß des Heizkörpers an die Heizmittelleitungen zu schaffen, ist das jeweils erste Grundelement G1 in seinem nabenartigen Fußbereich mit einem Anschlußstutzen AV versehen, der als ein mit Innengewinde versehenes, in das Grundelement G1 eingeschweißtes Rohrstück ausgebildet ist. Das diesem Grundelement G1 benachbarte, mit ihm durch Schweißnähte S im Bereich der Überströmöffnungen U verbundene Grundelement G2 ist im Fußbereich mit einem Anschlußstück AR für den Rücklauf des Heizmittels versehen. Auf diese Weise bilden die beiden Grundelemente G1 und G2 ein Standardelement für den Anschluß des jeweiligen Heizkörpers, und zwar unabhängig davon, wieviele weitere Grundelemente G3 bis G9 an das Grundelement G2 angeschlossen sind. Der Anschluß erfolgt - wie in Fig. 1 erkennbar - vorzugsweise durch zwei Schraubnippel N, die in Gewinderinge R des Grundelementes G2 und G3 eingreifen, wogegen die restlichen Grundelemente G3 bis G9 miteinander durch Schweißnähte S im Bereich ihrer Überströmöffnungen U miteinander flüssigkeitsdicht verbunden sind.In order to create a standard element for the connection of the radiator to the heating medium lines regardless of the number of basic elements, the first basic element G1 is provided in its hub-like foot region with a connecting piece A V , which is provided as an internally threaded pipe piece welded into the basic element G1 is trained. The basic element G1 adjacent to this basic element G1 and connected to it by weld seams S in the area of the overflow openings U is provided in the foot area with a connector A R for the return of the heating medium. In this way, the two basic elements G1 and G2 form a standard element for the connection of the respective radiator, regardless of how many further basic elements G3 to G9 are connected to the basic element G2. The connection is - as can be seen in Fig. 1 - preferably by two screw nipples N, which are in threaded rings R of the base element G2 and G3 intervene, whereas the remaining basic elements G3 to G9 are connected to one another in a liquid-tight manner by weld seams S in the region of their overflow openings U.
Auch in die jeweils freien Überströmöffnungen U des Grundelementes G1 und des Grundelementes G9 sind Gewinderinge R eingeschweißt. In diese Gewinderinge R des letzten Grundelementes G9 und in den Gewindering R im Fußbereich des Grundelementes G1 wird jeweils ein Verschlußstopfen VS eingeschraubt, wobei der Verschlußstopfen VS im Kopfbereich des Grundelementes G9 mit einer Öffnung für den Einsatz eines Entlüftungsventils versehen sein kann.Threaded rings R are also welded into the respective free overflow openings U of the base element G1 and the base element G9. A sealing plug VS is screwed into each of these threaded rings R of the last basic element G9 and into the threaded ring R in the foot region of the basic element G1, the sealing plug VS being able to be provided with an opening in the head region of the basic element G9 for the use of a vent valve.
Um ein Überströmen des durch den Anschlußstutzen AV für den Vorlauf eintretenden Heizmittels in den Fußbereich des Grundelementes G2 zu verhindern, ist die kreisförmige Überströmöffnung U im Fußbereich dieser beiden Grundelemente G1 und G2 durch eine Scheibe 1 verschlossen, die mittels eines Distanzstückes 2 durch den in den Gewindering R eingeschraubten Verschlußstopfen VS dichtend an den die Überströmöffnung U umgebenden Rand angepreßt wird. Die Scheibe 1 besteht aus dauerelastischem Material, vorzugsweise aus Gummi oder gummiartigem Kunststoff. Sie bildet auf diese Weise einen flüssigkeitsdichten Verschluß zwischen dem Fußbereich der beiden benachbarten Grundelemente G1 und G2. Das Distanzstück 2 ist vorzugsweise als Rohr ausgebildet.In order to prevent an overflow of the heating medium entering through the connecting piece A V for the flow into the foot area of the basic element G2, the circular overflow opening U in the foot area of these two basic elements G1 and G2 is closed by a disc 1, which by means of a
Durch die Verwendung einer derartigen Scheibe 1 und eines rohrförmigen Distanzstückes 2 wird beim Einschrauben des sowieso notwendigen Verschlußstopfens VS auf einfache Weise und ohne die Notwendigkeit zusätzlicher Schweißvorgänge eine flüssigkeitsdichte Abdichtung zwischen den Fußbereichen der beiden benachbarten Grundelemente G1 und G2 erreicht, so daß die gesamte Menge des durch den Anschlußstutzen AV für den Vorlauf eintretenden Heizmittels im Grundelement G1 nach oben strömt.By using such a washer 1 and a
Im Kopfbereich dieses Grundelementes G1 ist ein Ventilgehäuse 3 angeordnet, das im Längsschnitt in Fig. 4 dargestellt ist und vorzugsweise zur Aufnahme eines Thermostatventils dient. Das Einschrauben dieses Ventilgehäuses 3 in den Kopfbereich des Grundelements G1 erfolgt mit Hilfe des eingeschweißten Gewinderinges R unter Zwischenfügen einer Dichtung D. Am freien Ende des Ventilgehäuses 3 ist ein Bund 3a ausgebildet, der eine kegelförmige Mantelfläche und eine radial verlaufende, ringförmige Übergangsfläche bildet. Mit diesen beiden Flächen greift der Bund 3a in einen aus dauerelastischem Material, vorzugsweise Gummi oder gummiartigem Kunststoff hergestellten Ring 4 ein, der auf diese Weise einerseits zentriert und andererseits dichtend an den die Überströmöffnung U umgebenden Rand des mit dem Grundelement G2 durch eine Schweißnaht S verbundenen Grundelementes G1 angepreßt wird. Hierdurch erfolgt nicht nur eine Lagefixierung des innenliegenden Endes des Ventilgehäuses 3, sondern eine Abdichtung des Ventilgehäuses 3 gegenüber dem Kopfbereich des Grundelementes G1. Es wird somit sichergestellt, daß das Heizmittel ausschließlich durch das Ventilgehäuse 3 aus dem Kopfbereich des Grundelementes G1 in den Kopfbereich des Grundelementes G2 eintreten kann.A
Mit der voranstehend beschriebenen Konstruktion wird somit ohne zusätzliche Schweißvorgänge eine Abdichtung der das Standardelement bildenden Grundelemente G1 und G2 im Bereich der Anschlußstutzen AV und AR und eine Abdichtung des Ventilgehäuses 3 im Kopfbereich der Grundelemente G1 und G2 erreicht, und zwar durch Verwendung der aus dauerelastischem Material bestehenden Scheibe 1 bzw. des aus dauerelastischem Material bestehenden Ringes 4, wobei beide Teile durch Einschrauben des Verschlußstopfens VS bzw. des Ventilgehäuses 3 ihre Lage einnehmen und ihre Funktion ausüben. Ob und wieviele zusätzliche Grundelemente G3 bis G9 an das durch die Grundelemente G1 und G2 gebildete Standardelement mit Hilfe von Schraubnippeln N angefügt werden, hängt von der Heizleistung ab, die vom jeweiligen Heizkörper gefordert wird.With the construction described above, a sealing of the basic elements G1 and G2 forming the standard element in the area of the connecting pieces A V and A R and a sealing of the
