Description

Die Erfindung betrifft Armaturen zum Anschließen von Heizkörpern an Vorlauf und Rücklauf eines im Estrich verlegten Zweirohr-Heizungssystems gemäß dem Oberbegriff des Anspruchs 1.The invention relates to fittings for connecting radiators to the flow and return of a two-pipe heating system laid in the screed according to the preamble of claim 1.

Aus der DE-U 72 27 381 sind Heizkörperanschlußarmaturen für Zweirohr-Heizungssysteme mit geschoßweise im Estrich verlegten Vorlauf- und Rücklaufrohren bekannt, bestehend aus zwei U-förmigen Umlenkschleifen-Rohren, an deren Scheitel jeweils ein zum Heizkörper führender Abzweig vorgesehen ist.From DE-U 72 27 381 radiator connection fittings for two-pipe heating systems with floor and floor pipes in the screed supply and return pipes are known, consisting of two U-shaped deflection loop pipes, at the apex of which a branch leading to the radiator is provided.

Die DE-A 23 07 056 offenbart eine verbesserte Anschlußarmatur. Diese besteht aus zwei Teilen, die in einer waagerechten Ebene getrennt sind. Zwecks Anpassung an die örtlichen Verhältnisse - Lage der Anschlüsse an Vor- und Rücklaufrohr einerseits und Position des Heizkörpers andererseits - kann das obere Armaturteil auch um 90 Grad gedreht auf das untere Teil aufgesetzt und mittels einer zentralen Spannschraube verbunden werden. Für eine noch höhere Flexibilität kann auch das untere Armaturteil aus zwei Teilen bestehen, so daß insgesamt eine dreiteilige Anschlußarmatur vorliegt. Problematisch ist allerdings die einwandfreie Abdichtung zwischen den Einzelteilen der Armatur. Außerdem ist die bekannte Armatur nur für Heizkörper mit Koaxialanschluß von Vorlauf und Rücklauf geeignet.DE-A 23 07 056 discloses an improved connection fitting. This consists of two parts, which are separated in a horizontal plane. In order to adapt to the local conditions - position of the connections on the supply and return pipe on the one hand and position of the radiator on the other - the upper fitting part can also be turned by 90 degrees on the lower part and connected by means of a central clamping screw. For even greater flexibility, the lower fitting part can also consist of two parts, so that there is a total of a three-part connection fitting. The problem, however, is the perfect sealing between the individual parts of the valve. In addition, the known valve is only suitable for radiators with a coaxial connection of flow and return.

Die DE-A 40 17 689, DE-A 41 38 399 und DE-A 44 19 278 offenbaren Heizkörper-Anschlußarmaturen, die nur für den Wandeinbau geeignet sind. Dabei weist die Armatur der DE-A 44 19 278 die zusätzliche Besonderheit auf, daß mit Hilfe eines drehbaren Kükens Vorlauf und Rücklauf zum Heizkörper gewechselt werden können, so daß auch eine nicht normgerechte Verrohrung nachträglich noch korrigiert werden kann. Allerdings sind diese Armaturen groß, teuer und, wie erwähnt, nur für die Wandmontage geeignet.DE-A 40 17 689, DE-A 41 38 399 and DE-A 44 19 278 disclose radiator connection fittings which are only suitable for wall installation. The valve of DE-A 44 19 278 has the additional special feature that with the help of a rotatable plug feed and return to the radiator can be changed, so that even non-standard piping can be corrected later. However, these fittings are large, expensive and, as mentioned, only suitable for wall mounting.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Armatur zu vereinfachen und so auszubilden, daß eine flexible Anpassung an die gegebenen Bedingungen der Baustelle möglich ist.The present invention has for its object to simplify the generic armature and design so that a flexible adaptation to the given conditions of the site is possible.

Diese Aufgabe wird gelöst durch eine Armatur mit den Merkmalen des Anspruchs 1.This object is achieved by a fitting with the features of claim 1.

Die erfindungsgemäße Armatur besteht aus zwei getrennten Teilarmaturen, von denen jede einen kompletten Anschlußbogen mit zum Heizkörper abzweigendem Verbindungskanal sowie die bewährten Rohranschlüsse umfaßt. Dichtungsprobleme können daher nicht auftreten. Erhebungen an den Seitenwänden der Teilarmaturen sorgen für den normgerechten gegenseitigen Abstand, so daß die Teilarmaturen selbst optimal schlank ausgeführt werden können, was Material, Gewicht und Kosten sparen hilft.The fitting according to the invention consists of two separate part fittings, each of which comprises a complete connection bend with a connecting duct branching off to the radiator, as well as the proven pipe connections. Sealing problems can therefore not occur. Elevations on the side walls of the partial fittings ensure the standard mutual spacing, so that the partial fittings themselves can be made optimally slim, which helps to save material, weight and costs.

Die Abmessungen der Teilarmaturen und der angeformten Erhebungen sind vorzugsweise so aufeinander abgestimmt, daß die Mittelachsen der vier bodenseitigen Rohranschlüsse auf den Ecken eines Quadrates sitzen.The dimensions of the partial fittings and the molded elevations are preferably matched to one another in such a way that the central axes of the four bottom-side pipe connections sit on the corners of a square.

Gemäß einer Ausgestaltung der Erfindung sind die Erhebungen an beiden Seitenwänden einer Teilarmatur, vorzugsweise der Rücklauf-Teilarmatur, angeformt. Dadurch bleiben die jeweils unbenutzten Erhebungen der Raumwand zugekehrt und fallen nicht auf.According to one embodiment of the invention, the elevations are formed on both side walls of a partial fitting, preferably the return partial fitting. As a result, the unused elevations remain facing the wall of the room and are not noticeable.

Alternativ dazu besteht auch die Möglichkeit, an beiden Teilarmaturen Erhebungen halber Höhe anzuformen. Dadurch erhält die fertig montierte Armatur ein symmetrisches Aussehen. Der wesentliche Vorteil besteht darin, daß beide Teilarmaturen in derselben Gußform hergestellt werden können.Alternatively, there is also the option of using both Partial fittings to form half-height surveys. This gives the assembled valve a symmetrical appearance. The main advantage is that both fittings can be made in the same mold.

Zentrierzapfen und -vertiefungen an den Erhebungen und/oder an den Seitenwänden der Teilarmaturen sorgen für die korrekte gegenseitige Positionierung.Centering pins and recesses on the elevations and / or on the side walls of the partial fittings ensure correct mutual positioning.

Um die beiden Teilarmaturen sicher und dauerhaft miteinander verbinden zu können, ist an der einen Teilarmatur eine Durchgangsbohrung für eine Verbindungsschraube vorgesehen, während die andere Teilarmatur korrespondierende Gewindebohrungen aufweist. Die Durchgangsbohrung kann auch als Schlitz ausgeführt sein.In order to be able to securely and permanently connect the two sub-fittings to one another, a through-hole for a connecting screw is provided on one sub-fitting, while the other sub-fitting has corresponding threaded bores. The through hole can also be designed as a slot.

Eine besonders günstige Gestaltung erhält man, wenn gemäß einer bevorzugten Weiterbildung der Erfindung die Mittelachse des heizkörperseitigen Rohranschlusses mit der Mittelachse eines der bodenseitigen Rohranschlüsse fluchtet.A particularly favorable design is obtained if, according to a preferred development of the invention, the central axis of the radiator-side pipe connection is aligned with the central axis of one of the bottom-side pipe connections.

Diese und weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.These and other embodiments of the invention are the subject of the dependent claims.

Fig. 1 zeigt eine Heizkörper-Anschlußarmatur 1, bestehend aus zwei Teilarmaturen 10, 11, als Vorderansicht, Draufsicht, Rückansicht und Querschnitt B-B. Jede Teilarmatur 10, 11 enthält einen U-förmigen Durchleitkanal 12 mit bodenseitigen Rohranschlüssen 15 und einen von den Durchleitkanälen 12 abzweigenden Verbindungskanal 16, 17 mit heizkörperseitigen Rohranschlüssen 18.Fig. 1 shows a radiator connection fitting 1, consisting of two partial fittings 10, 11, as a front view, top view, rear view and cross section B-B. Each fitting 10, 11 contains a U-shaped feed-through channel 12 with tube connections 15 at the bottom and a connection channel 16, 17 branching off from the feed-through channels 12 with tube connections 18 on the radiator side.

Die Rücklauf-Teilarmatur 10 besitzt an beiden Seitenwänden Erhebungen 22, 22'. Zentrierzapfen und -vertiefungen 20, 21 an den Erhebungen 22, 22' bzw. den Seitenwänden der anderen Teilarmatur 11 sorgen für einen abstands- und paßgenauen Sitz der beiden Teilarmaturen 10, 11.The return partial fitting 10 has elevations 22, 22 'on both side walls. Centering pegs and recesses 20, 21 on the elevations 22, 22 'and the side walls of the other sub-fitting 11 ensure that the two sub-fittings 10, 11 are seated precisely and at a precise distance.

Die Verbindung der beiden Teilarmaturen 10, 11 erfolgt mit Hilfe einer Verbindungsschraube 23. Hierzu besitzt die eine Teilarmatur 10 eine Durchgangsbohrung, die andere Teilarmatur 11 eine Gewindebohrung 24.The connection of the two partial fittings 10, 11 takes place with the aid of a connecting screw 23. For this purpose, one partial fitting 10 has a through hole, the other partial fitting 11 has a threaded hole 24.

Dank dieser Ausgestaltung lassen sich die beiden Teilarmaturen 10, 11 spiegelbildlich zueinander montieren, so daß eine flexible Anpassung an die Gegebenheiten der Baustelle möglich ist.Thanks to this configuration, the two partial fittings 10, 11 can be mounted in mirror image to one another, so that a flexible adaptation to the conditions of the construction site is possible.

Die entsprechende Anwendung zeigt Fig. 2. Man erkennt ein Zweirohr-Heizungssystem, dessen Vorlaufrohre 3 und Rücklaufrohre 4 im Estrich parallel zur Raumwand verlegt sind. Um die Verbindung zu Heizkörpern 2 mit Ventil 5.rechts und Heizkörpern 2' mit Ventil 5 links vornehmen zu können, werden die beiden Teilarmaturen 10, 11 spiegelbildlich wechselweise miteinander verschraubt und mit den Vorlaufund Rücklaufrohren 3, 4 bzw. den Heizkörperanschlüssen verbunden. Sollten einmal Vor- und Rücklaufrohre 3, 4 verwechselt worden sein, so läßt sich auch dies korrigieren. Die Erhebungen 22' an den Rücklauf-Teilarmaturen 10 sind der Raumwand zugekehrt und bleiben für den Betrachter unsichtbar.The corresponding application is shown in FIG. 2. A two-pipe heating system can be seen, the supply pipes 3 and return pipes 4 of which are laid in the screed parallel to the room wall. In order to be able to make the connection to radiators 2 with valve 5 on the right and radiators 2 'with valve 5 on the left, the two sub-fittings 10, 11 are screwed alternately in mirror image and connected to the flow and return pipes 3, 4 and the radiator connections. If feed and return pipes 3, 4 have been mixed up, this can also be corrected. The elevations 22 'on the return fittings 10 face the room wall and remain invisible to the viewer.

Die aus dem Estrich bzw. Bodenbelag senkrecht austretenden Vor- und Rücklaufrohre 3, 4 sowie die auf deren Enden befestigte Armatur 1 können mit Hilfe einer Abdeckblende 30 verkleidet werden. Dies ist in Fig. 5 als Vorderansicht, in Fig. 3 als Rückansicht, in Fig. 4 als teilgeschnittene Draufsicht und in Fig. 6 als Querschnitt entlang der Linie VI-VI in Fig. 5 dargestellt.The supply and return pipes 3, 4 emerging vertically from the screed or floor covering and the fitting 1 fastened to their ends can be covered with a cover panel 30. This is shown in FIG. 5 as a front view, in FIG. 3 as a rear view, in FIG. 4 as a partially sectioned top view and in FIG. 6 as a cross section along the line VI-VI in FIG. 5.

Die Abdeckblende 30 ist etwa U-förmig gebogen. Sie besitzt einen federnd geschlitzten Deckel 31, der zwischen den Verbindungskanälen 16, 17 bzw. den heizkörperseitigen Rohranschlüssen 18 einrastet. Die Innenseite der Abdeckblende 30 trägt einen Halter 32, der auf den bodenseitigen Rohranschlüssen 15 aufrastet. Dank geeigneter Ausschnitte bleiben die Verschlußkappen 25 der Absperr- und Entleerungsöffnungen frei zugänglich.The cover panel 30 is bent approximately in a U-shape. It has a resiliently slotted cover 31 which engages between the connecting channels 16, 17 or the radiator-side pipe connections 18. The inside of the cover panel 30 carries a holder 32 which snaps onto the tube connections 15 on the bottom. Thanks to suitable cutouts, the caps 25 of the shut-off and emptying openings remain freely accessible.

Die Mittelachsen der bodenseitigen Rohranschlüsse 15 liegen auf den Ecken eines Quadrates 40.The central axes of the pipe connections 15 on the bottom lie on the corners of a square 40.

Fig. 7 zeigt einen Längsschnitt durch die Rücklauf-Teilarmatur 10, aufgeschraubt auf die Enden der Rücklaufrohre 4. Man erkennt den U-förmigen Durchleitkanal 12, der die beiden bodenseitigen Rohranschlüsse 15 verbindet, sowie den von dem Durchleitkanal 12 abzweigenden Verbindungskanal 16 mit seinem heizkörperseitigen Rohranschluß 18. Die Mittelachse 28 des heizkörperseitigen Rohranschlusses 18 fluchtet mit der Mittelachse eines der beiden bodenseitigen Rohranschlüsse 15.7 shows a longitudinal section through the return partial fitting 10, screwed onto the ends of the return pipes 4. The U-shaped feed-through channel 12, which connects the two pipe connections 15 on the bottom, and the connecting channel 16 branching off from the pass-through channel 12 with its radiator-side Pipe connection 18. The central axis 28 of the radiator-side pipe connection 18 is aligned with the central axis of one of the two bottom-side pipe connections 15.

Der Verbindungskanal 16 kann mit Hilfe einer Absperrschraube 26 mit integrierter Entleerung abgesperrt werden, beispielsweise um Reparaturen am Heizkörper vornehmen zu können, ohne die gesamte Heizungsanlage entleeren zu müssen. Ein eingeformter Schwerkraftstopp 27 verhindert wirksam unerwünschte Strömungen des Heizmediums bei abgesperrtem Heizkörperventil 5.The connecting channel 16 can be shut off with the aid of a shut-off screw 26 with integrated drainage, for example in order to be able to carry out repairs on the radiator without having to drain the entire heating system. A molded-in gravity stop 27 effectively prevents undesired flows of the heating medium when the radiator valve 5 is shut off.
