Abstract
Description
Die Erfindung betrifft eine Armatur zum Anschließen von Heizkörpern an Vorlauf und
Rücklauf eines im Estrich verlegten Zweirohr-Heizungssystems gemäß dem
Oberbegriff des Anspruchs 1.The invention relates to a fitting for connecting radiators to flow and
Return of a two-pipe heating system laid in the screed according to the
Preamble of
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.DE-U 72 27 381 discloses radiator connection fittings for two-pipe heating systems with flow and return pipes laid in the screed on each floor known, consisting of two U-shaped deflection loop tubes, at the apex In each case a branch leading to the radiator is provided.
Die DE-A 23 07 056, die als nächstliegender Stand der Technik angesehen wird, 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° 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, which is considered the closest prior art, discloses an improved connection fitting. This consists of two parts, which in are separated on a horizontal plane. To adapt to the local Conditions - location of the connections to the supply and return pipe on the one hand and position the radiator on the other hand - the upper fitting can also be turned 90 ° the lower part is attached and connected by means of a central clamping screw become. For even greater flexibility, the lower fitting part can also consist of two Parts exist, so that there is a three-part connection fitting. The problem, however, is the perfect seal between the individual parts of the Fitting. In addition, the known valve is only for radiators with coaxial connection suitable for forward and reverse.
Die DE-A 40 17 689, DE-A 41 38 899 und DE-A 44 19 278 offenbaren HeizkörperAnschlussarmaturen, die nur für den Wandeinbau geeignet sind. Dabei weist die Armatur der DE-A 4419 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 38 899 and DE-A 44 19 278 disclose radiator connection fittings, which are only suitable for wall installation. The Armature of DE-A 4419 278 the additional special feature that with the help of a rotatable chick flow and return to the radiator can be changed so that one is not standard piping can be corrected later can. However, these fixtures are big, expensive, and how 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 is based on the object to simplify the generic fitting and to design it in such a way that a flexible adaptation to the given conditions of Construction site is possible.
Diese Aufgabe wird gelöst durch eine Armatur mit den
Merkmalen des Anspruchs 1.This task is solved by a valve with the
Features of
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 ones Partial fittings, each of which is a complete connection bend with connecting duct branching off to the radiator and the proven pipe connections. Sealing problems can therefore do not occur. Elevations on the side walls of the Partial fittings ensure that standards are mutual Distance, so that the partial fittings themselves optimally slim can run what material, weight and cost saving helps.
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 ones Elevations are preferably coordinated so that the central axes of the four bottom pipe connections 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 an embodiment of the invention, the surveys on both side walls of a partial fitting, preferably the Return fitting, molded. This keeps them each unused elevations of the room wall turned and fall not on.
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. Thereby the assembled valve receives a symmetrical one Appearance. The main advantage is that both Partial fittings are made in the same mold can.
Zentrierzapfen und -vertiefungen an den Erhebungen und an den Seitenwänden der Teilarmaturen sorgen für die korrekte gegenseitige Positionierung.Centering pin and recesses on the elevations and on the side walls of the partial fittings ensure that 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.To secure the two sub-fittings together permanently To be able to connect is on one of the fittings Through hole provided for a connecting screw, while the other sub-fitting corresponds Has threaded holes. 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 Central axis of the radiator pipe connection with the The central axis of one of the bottom pipe connections is aligned.
