Abstract

The concrete invention relates to a coupling element for radiators for hot-water central heating installations, which is particularly suitable for mounting on or in walls and makes possible on the one hand a connection to the forward run and return run pipe of the heating system pipe train and on the other hand the forward and return run connection to the central heating body. A bore - called short circuit bore 6 in the following - connects the forward run connections 2 to the return run connections 3 so that a flow is possible through the pipe network even when the central heating valve is shut off. As a result of the installation of cylindrical bushes 7, alternatively in the forward run connection 2 or even in the forward and in the return run connection 3, in each case an annular gap 8 is produced, through which, when the radiator valve is closed, the entire circulated train water quantity can flow off via the short-circuit bore 6 completely and with low noise. When the radiator valve is open, one part flow of the circulated train water quantity flows off through the radiator and the other part flow via the short-circuit bore 6 into the return run pipe 3. The part flow of the heating water flowing through the radiator is recombined, in the region of the connection bore 3 for the return run pipe, with the part flow which flows via the short-circuit bore 6. The length of the cylindrical bush 7 (bushes) and the possible complete or partial overlapping therewith of the short-circuit bore 6 define(s) the quantity division of the heating water since, with longer bushes 7, the resistance in the short-circuit bore 6 is increased and, with shorter bushes 7, on the other hand decreased. Accordingly, a part flow also flows through the radiator and the remainder of the train water quantity through the short-circuit bore 6. <IMAGE>

Description

Die gegenständliche Erfindung befaßt sich mit einem HeizkörperAnschlußelement für Warmwasser-Zentralheizungsanlagen, das sich für die Montage an oder in Wänden eignet, einerseits eine Verbindung mit der Vorlauf- und Rücklaufleitung des Heizungsrohrstranges und andererseits den Vor- und Rücklaufanschluß an den Zentralheizungskörper ermöglicht.The present invention is concerned with a radiator connection element for hot water central heating systems, which is suitable for mounting on or in walls, on the one hand a connection to the flow and return line of the heating pipe string and on the other hand allows the flow and return connection to the central heating element.

Eine Bohrung - im nachfolgenden Kurzschlußbohrung genannt - verbindet die Vorlaufanschlüsse mit den Rücklaufanschlüssen, sodaß auch eine Durchströmung des Rohrnetzes bei abgesperrten Zentralheizungsventil möglich ist.A hole - called short-circuit hole in the following - connects the flow connections with the return connections, so that a flow through the pipe network is also possible when the central heating valve is shut off.

Durch den Einbau von zylindrischen Buchsen, wahlweise in den Vorlaufanschluß oder auch in den Vorlauf- und in den Rücklaufanschluß, entsteht jeweils ein ringförmiger Spalt, durch den bei geschlossenem Heizkörperventil die gesamte umgewälzte Strangwassermenge zur Gänze und geräuscharm über die Kurzschlußbohrung abfließen kann.The installation of cylindrical bushings, either in the flow connection or in the flow and return connections, creates an annular gap through which the entire circulated water volume can flow completely and quietly through the short-circuit hole when the radiator valve is closed.

Bei geöffnetem Heizkörperventil fließt ein Teilstrom der umgewälzten Strangwassermenge durch den Heizkörper und der andere Teilstrom über die Kurzschlußbohrung in die Rücklaufleitung ab. Der durch den Heizkörper fließende Teilstrom des Heizungswassers vereinigt sich im Bereich der Anschlußbohrung für die Rücklaufleitung wieder mit dem Teilstrom, der über die Kurzschlußbohrung fließt.When the radiator valve is open, a partial flow of the circulated water flow flows through the radiator and the other partial flow flows through the short-circuit hole into the return line. The partial flow of the heating water flowing through the radiator combines again in the area of the connection bore for the return line with the partial flow that flows through the short-circuit bore.

Die Länge der zylindrischen Buchse (Buchsen) und die damit eventuelle ganze oder teilweise Überdeckung der Kurzschlußbohrung bestimmt (bestimmen) die Mengenaufteilung des Heizungswassers, da sich bei längeren Buchsen der Widerstand in der Kurzschlußbohrung erhöht, bzw. bei kürzeren Buchsen hingegen verringert. Entsprechend fließt auch ein Teilstrom durch den Heizkörper und der Rest der Strangwassermenge durch die Kurzschlußbohrung.The length of the cylindrical socket (sockets) and the possible total or partial coverage of the short-circuit bore determines the quantity distribution of the heating water, since the resistance in the short-circuit bore increases with longer sockets increased, or reduced for shorter sockets. Correspondingly, a partial flow also flows through the radiator and the rest of the strand water flow through the short circuit hole.

Der zwischen dem Gehäuse des Heizkörper-Anschlußelementes und der zylindrischen Buchse entstehende Ringspalt verursacht eine Richtungsumkehr des in die Kurzschlußbohrung einfließenden Teilwasserstromes und erzeugt dadurch einen entsprechenden Druckverlust, der für eine Funktion des Anschluβelementes - Aufteilung des Heizungswasserstromes in Heizkörperdurchflußmenge einerseits und in die Kurzschlußstreckendurchflußmenge andererseits - notwendig ist. Durch diesen ringförmigen Spalt werden aber auch Strömungsgeräusche, wie sie sonst bei Kurzschlußbohrungen auftreten können vermieden, auch wenn größere Wassermengen durcströmen.The annular gap that arises between the housing of the radiator connection element and the cylindrical bushing causes a reversal of the direction of the partial water flow flowing into the short-circuit bore and thereby generates a corresponding pressure loss that is necessary for a function of the connection element - division of the heating water flow into the radiator flow rate on the one hand and into the short-circuit path flow rate on the other hand is. This annular gap also avoids flow noises that can otherwise occur with short-circuit bores, even when larger amounts of water flow through.

Wandeinbauelemente für den Anschluß von Warmwasser-Zentralheizkörpern sind bekannt und dienen in den meisten Fällen als Übergangs- und Verbindungsstücke von beispielsweise Kunststoffrohrleitungen zu den Anschlußarmaturen der Zentralheizungskörper, die im Regelfalle aus anderen Werkstoffen gefertigt sind.Wall mounting elements for the connection of hot water central radiators are known and are used in most cases as transition and connecting pieces of, for example, plastic pipes to the connection fittings of the central heating element, which are usually made of other materials.

Diese Wandeinbauelemente können als Einzelelemente z.B. nur für den Vorlauf- und getrennt nur für Rücklaufanschluß geeignet sein, oder aber die beiden Anschlüsse sind in einem Element zusammengefaßt, weisen aber zwischen den Vor- und Rücklaufleitungsanschlüssen keine hydraulische Verbindung (Kurzschlußbohrung) auf.These built-in wall elements can be used as individual elements e.g. only suitable for the flow connection and separately only for the return connection, or the two connections are combined in one element, but do not have a hydraulic connection (short-circuit hole) between the supply and return line connections.

Mit der AT-A-306 974 wurde eine Anschlußarmatur für Radiatoren bei Einrohrheizungen bekannt, die im wesentlichen aus einem kompakten Formstück besteht, das sowohl Vor- und Rücklaufanschlüsse für den Heizkörper, als auch Anschlüsse für die Vor- und Rücklaufleitungen besitzt und auch einen Verbindungskanal zwischen Vor- und Rücklaufleitung (Kurzschlußbohrung) aufweist.With AT-A-306 974 a connection fitting for radiators in single-pipe heating systems was known, which essentially consists of a compact fitting, which both Has supply and return connections for the radiator, as well as connections for the supply and return lines and also has a connecting channel between the supply and return lines (short-circuit hole).

Die vorliegende Erfindung stellt ein Heizkörper-Anschlußelement vor, das neben der Verbindung zwischen Rohrleitung und Heizkörper auch noch eine zusätzliche, hydraulische Funktion erfüllt. Durch eine Verbindungsbohrung (Kurzschlußbohrung) zwischen Vorlaufanschluß und Rücklaufanschluß wird bei geöffnetem Heizkörperventil ein Teilstrom und bei geschlossenem Heizkörperventil die gesamte Strangwassermenge durch diese Kurzschlußbohrung durchfließen. Die Mengenaufteilung zwischen der Wassermenge, die durch den Heizkörper fließen soll und der restlichen Wassermenge, die durch die Kurzschlußbohrung fließt, wird durch den Einbau von zylindrischen Buchsen in den Vorlauf- und wahlweise auch in den Rücklaufteil des Heizkörper-Anschlußelementes, bewerkstelligt.The present invention presents a radiator connecting element which, in addition to the connection between the pipeline and the radiator, also fulfills an additional hydraulic function. Through a connection hole (short-circuit hole) between the flow connection and the return connection, a partial flow will flow through this short-circuit hole when the radiator valve is open and the entire amount of string water when the radiator valve is closed. The quantity distribution between the amount of water that should flow through the radiator and the remaining amount of water that flows through the short-circuit hole is achieved by installing cylindrical bushings in the flow and optionally also in the return part of the radiator connection element.

In der beiliegenden Zeichnung, Fig. 1, ist ein solches Heizkörper-Anschlußelement im Schnitt dargestellt. Im Gehäuse 1 des Elementes sind die Anschlußbohrungen für die Aufnahme der Vorlaufrohrleitung 2 und der Rücklaufrohrleitung 3 sinngemäß zugeordnet, sowie die Anschlüsse für den Heizkörper-Vorlaufanschluß 4 und den Heizkörper-Rücklaufanschluß 5 untergebracht. Die Kurzschlußbohrung 6 verbindet die Vorlaufanschlüsse 2 und 4 mit den Rücklaufanschlüssen 3 und 5. In den Vorlaufanschluß 2 ist die zylindrische Buchse 7 eingebaut, deren oberer Teil mit der Vorlaufanschlußbohrung 2 den Ringspalt 8 bildet.In the accompanying drawing, Fig. 1, such a radiator connection element is shown in section. In the housing 1 of the element, the connection bores for receiving the flow pipe 2 and the return pipe 3 are correspondingly assigned, and the connections for the radiator flow connection 4 and the radiator return connection 5 are accommodated. The short-circuit bore 6 connects the flow connections 2 and 4 to the return connections 3 and 5. In the flow connection 2, the cylindrical bushing 7 is installed, the upper part of which forms the annular gap 8 with the flow connection bore 2.

Bei geöffnetem Heizkörperventil (in der Zeichnung nicht dargestellt) fließt ein Teil der umgewälzten Strangwassermenge durch den Heizkörper-Vorlaufanschluß in den Heizkörper ein, durchströmt diesen, verläßt ihn über den Heizkörper-Rücklaufanschluß 4 und fließt in den Rohrleitungsanschluß 5 ab. Der restliche Teil der Strangwassermenge fließt über den Ringspalt 8 in die Kurzschlußbohrung 6 ein und verbindet sich im Rücklaufanschluß 5 wieder mit dem aus dem Heizkörper kommenden Teilstrom.When the radiator valve is open (not shown in the drawing), part of the circulated water flow flows through the radiator flow connection into the radiator, flows through it, leaves it via the radiator return connection 4 and flows into the pipeline connection 5. The remaining part of the strand water flow flows through the annular gap 8 into the short-circuit bore 6 and connects in the return connection 5 again with the partial flow coming from the radiator.

Ist nun das Heizkörperventil vollständig geschlossen, so findet keine Durchströmung des Heizkörpers statt und die gesamte umgewälzte Strangwassermenge fließt über den Ringspalt 8, die Kurzschlußbohrung 6 und über die Rücklaufbohrung 5 in das Rohrleitungsnetz zurück.If the radiator valve is now completely closed, there is no flow through the radiator and the entire circulated amount of strand water flows back into the pipeline network via the annular gap 8, the short-circuit bore 6 and the return bore 5.

In Fig. 2 ist dasselbe Heizkörper-Anschlußelement im Schnitt dargestellt, doch ist hier auch in der Rücklaufanschluß 3 eine Buchse 7 eingebaut, die wiederum mit dem Gehäuse 1 einen weiteren Ringspalt 8 bildet. Die Länge der Buchse 7 bestimmt, wie weit die Kurzschlußbohrung abgedeckt wird und beeinflußt damit den Durchflußwiderstand, der für die durch die Kurzschlußbohrung 6 fließende Teilstromwassermenge bestimmend ist.In Fig. 2 the same radiator connection element is shown in section, but here a socket 7 is also installed in the return connection 3, which in turn forms a further annular gap 8 with the housing 1. The length of the bushing 7 determines how far the short-circuit bore is covered and thus influences the flow resistance, which is decisive for the amount of partial flow water flowing through the short-circuit bore 6.

In Fig. 3 ist ein Wandelement im eingebauten Zustand beispielhaft dargestellt. Das im Schnitt durch die Vorlaufanschlüsse gezeichnete Gehäuse 1 ist mit der Rohrleitung 9 wasserdicht verbunden. Über einen Rohrnippel 10 und eine Heizkörper-Anschlußverschraubung 11 wird die Verbindung zum Heizkörper 12 hergestellt. Das Anschlußelement 1 ist zur Gänze in der Wandkonstruktion 13 und die Rohrleitung 9 teilweise in der Wand 13 und zum anderen Teil in der Bodenkonstruktion 14 untergebracht.3 shows an example of a wall element in the installed state. The housing 1 shown in section through the flow connections is connected to the pipeline 9 in a watertight manner. The connection to the radiator 12 is established via a pipe nipple 10 and a radiator screw connection 11. The connecting element 1 is entirely housed in the wall construction 13 and the pipeline 9 partly in the wall 13 and the other part in the floor construction 14.
