Abstract
Description
Die Erfindung betrifft eine Rohrverbindung für fluid- und gasführende Installationen mit den Merkmalen des Oberbegriffs Schutzanspruch 1 bis 7.The The invention relates to a pipe joint for fluid and gas installations with the features of the preamble protection claim 1 to 7.
Es wird allgemein verlangt, dass eine Rohrverbindung, bestehend aus einem Kunststoff- oder Kunststoff-Metall-Kunststoff Verbundrohr und dem Grundkörper der Rohrverbindung dicht ist. Besonders unter hohen Temperaturen und Druckbelastungen ist die Dichtheit der Rohrverbindung von entscheidender Bedeutung.It is generally required that a pipe joint consisting of a plastic or plastic-metal-plastic composite pipe and the body the pipe connection is tight. Especially under high temperatures and pressure loads, the tightness of the pipe joint is more crucial Importance.
Des Weiteren wird ein Produkt verlangt, dessen Installation einfach und schnell auszuführen ist und zudem günstig in der Herstellung ist.Of Further, a product is required, its installation easy and execute quickly is and cheap is in production.
Bekannt sind sogenannte Klemmringverschraub-Verbindungen mit gummielastischen Dichtungen und metallischen Zwischenringen, als auch Pressverbindungen, bei denen das Rohr durch plastische Verformung einer Presshülse gegen den Grundkörper der Rohrverbindung gepresst wird, als auch Schiebehülsenverbindungen, bei denen eine zusätzliche Metallhülse auf das Rohrende und auf den Grundkörper der Verbindung aufgesetzt wird. Diese werden sowohl bei Trinkwasser-, als auch für Heizungs- und Kühlungsinstallationen angewandt und werden in Form von Kupplungs-, T-Stück-, Winkel-, Winkelbogen-, Verteilerteilen und Ftittingen gefertigt.Known are so-called Klemmringverschraub connections with rubber-elastic Seals and metallic intermediate rings, as well as press connections, in which the tube by plastic deformation of a compression sleeve against the main body the pipe joint is pressed, as well as sliding sleeve joints, where an additional metal sleeve placed on the pipe end and on the body of the connection becomes. These are used for both drinking water and heating and cooling installations applied and used in the form of coupling, tee, Angle, elbow, distributor parts and Ftittingen made.
Alle von den bereits bekannten Rohrverbindungen erfüllen zwar das Kriterium der Dichtheit, manche auch unter Druck- und Temperaturbelastungen. Jedoch sind meistens die Herstellungskosten solcher hoch und meistens sind diese nur unter großem Zeitaufwand montierbar.All Of the already known pipe joints meet the criterion of Tightness, some even under pressure and temperature loads. however Mostly the manufacturing costs are high and mostly these only under large Time can be mounted.
Der Erfindung liegt die Aufgabe zugrunde, eine Rohrverbindung zu schaffen, die kostengünstig herzustellen ist, einfach zu montieren ist und insbesondere auch unter höheren Temperatur und höherem Druck standfest und dicht ist.Of the Invention has for its object to provide a pipe connection, the inexpensive to produce is easy to assemble and especially under higher temperature and higher Pressure is stable and tight.
Zur Lösung dieser Aufgabe wird eine Rohrverbindung nach dem Schiebehülsenprinzip vorgeschlagen, die am Grundkörper einen Rohranschlussabschnitt aufweist, worauf das anzuschließende Rohr anliegt. Diese Rohrverbindung ist erfindungsgemäß dadurch gekennzeichnet, dass der Grundkörper der Rohrverbindung eine Einrastrille und die Schiebehülse einen Einrastzahn aufweist. Diese werden durch axiale Verschiebung der Schiebehülse kraftschlüssig ineinander gepresst und somit verhakt. Die Schiebehülse besteht aus zwei Teilen – einer Außenhülse aus Metall und einer Innenhülse aus Kunststoff. Die Innenhülse gewährleistet durch den Einrastzahn sicheren Halt der Hülse am Grundkörper, während die Metallhülse für konstanten Anpressdruck des Rohres auf den Grundkörper sorgt und der Schiebehülse mechanische Stabilität verleiht. Zwischen Schiebehülse und Grundkörper kann ein Dichtungsring aus elastischem Material verwendet werden. Diese Verbindung ist sowohl bei Kalibrier- als auch bei Rohraufweitsystemen verwendbar. Soweit bekannt, ist dies das erste Rohraufweitsystem, bei dem ein Einrastzahn/Einrastrille aus Kunststoff und eine O-Ring-Dichtung verwendet wird.to solution This task is a pipe connection according to the sliding sleeve principle suggested that on the main body having a pipe connection portion, whereupon the pipe to be connected is applied. This pipe connection is inventively characterized in that the main body of the Pipe joint a snap-in groove and the sliding sleeve one Has a latch tooth. These are due to axial displacement of the sliding sleeve force fit pressed into each other and thus hooked. The sliding sleeve is made from two parts - one Outer sleeve off Metal and an inner sleeve made of plastic. The inner sleeve guaranteed by the Einrastzahn secure hold of the sleeve on the body, while the metal sleeve for constant Contact pressure of the tube on the body provides and the sliding sleeve mechanical stability gives. Between sliding sleeve and basic body a sealing ring made of elastic material can be used. These Connection is in both calibration and pipe expansion systems usable. As far as is known, this is the first pipe expansion system, where a Einrastzahn / Einrastrille plastic and an O-ring seal is used.
Bei Testversuchen erwies sich diese Verbindung auch unter hohen thermischen und mechanischen Belastungen als äußerst standfest. Dies ist nicht zuletzt auf den Einrastzahn zurückzuführen, der ein Abgleiten der Schiebehülse verhindert. Dieses Abgleiten tritt meistens nach einer Zeit bei häufigen und großen Temperaturschwankungen ein, als Folge der länglichen Ausdehnungen des Rohres – bei Multiverbundrohren wegen verschiedener Ausdehnungskoeffizienten derer Schichten.at Trials proved this compound even under high thermal and mechanical loads as extremely stable. this is not due last to the Einrastzahn, the one Sliding the sliding sleeve prevented. This slipping usually occurs after a while frequent and huge Temperature fluctuations, as a result of the elongated dimensions of the tube - in multi-manifolds because of different coefficients of expansion of these layers.
Des Weiteren ist das System relativ einfach und kostengünstig herstellbar. Auch der Montageaufwand ist mit diesem System gering. Die Montage unterscheidet sich kaum von der bei den bisher gängigen Schiebehülsensystemen.Of Furthermore, the system is relatively easy and inexpensive to produce. The assembly effort is low with this system. The assembly hardly differs from the previously common sliding sleeve systems.
Erfindungsgemäß besteht der Grundkörper der Rohrverbindung aus Kunststoff oder Metall, die Schiebehülse besteht aus einer Außenhülse aus Metall und einer Innenhülse aus Kunststoff. Die Außen- und die Innenhülse bilden zusammen eine Einheit. Die äußere Metallhülse weist im Inneren eine Zacke auf, die das Abrutschen von der Kunststoffhülse verhindert. Der Rohranschlussabschnitt des Grundkörpers weist auf seiner Rohranliegefläche ein Sägezahnprofil auf.According to the invention the main body of the Pipe connection made of plastic or metal, the sliding sleeve consists from an outer sleeve Metal and an inner sleeve made of plastic. The exterior and the inner sleeve together form a unity. The outer metal sleeve has inside a spike, which prevents slipping off the plastic sleeve. The pipe connection portion of the body has on its Rohranliegefläche sawtooth on.
Die Ausführungsbeispiele der neuen Rohrverbindung sind in den Zeichnungen dargestellt und werden im Folgenden näher erläutert. Es zeigenThe embodiments the new pipe joint are shown in the drawings and will in the following explained. Show it
