Description
Die
Erfindung betrifft einen Rohrverbinder für Flüssigkeits- und Gasleitungen
nach dem Oberbegriff des Patentanspruchs 1. Ein solcher Rohrverbinder
ist Gegenstand des deutschen Gebrauchsmusters
Es wird allgemein verlangt, dass eine Rohrverbindung, bestehend aus einem Kunststoffrohr oder einem Kunststoff-Metall-Kunststoff-Verbundrohr und dem Grundkörper der Rohrverbindung dicht ist. Besonders bei hohen Temperaturen und Druckbelastungen ist die Dichtheit der Rohrverbindung von entscheidender Bedeutung.It is generally required that a pipe joint consisting of a plastic pipe or a plastic-metal-plastic composite pipe and the main body the pipe connection is tight. Especially at high temperatures and Pressure loads is the tightness of the pipe connection of more crucial Importance.
Des weiteren wird ein Produkt verlangt, dessen Installation einfach und schnell auszuführen und zudem günstig in der Herstellung ist.Of Further, a product is required, its installation easy and execute quickly and also cheap is in production.
Bekannt sind Klemmringschraubverbindungen mit gummielastischen Dichtungen und metallischen Zwischenringen sowie 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 sowie Gasinstallationen angewandt und werden in Form von Kupplungs-, T-Stück-, Winkel-, Winkelbogen-, Verteilerteilen und Fittingen gefertigt.Known are Klemmringschraubverbindungen with rubber-elastic seals and metallic intermediate rings and compression joints, in which the pipe against by plastic deformation of a compression sleeve the main body the pipe joint is pressed, as well as sliding sleeve joints, where an additional Metal sleeve on the pipe end and on the body the connection is set up. These are used in both drinking water, as well as for Heating and cooling installations gas installations and are used in the form of coupling, T-Pieces, Angular, elbow, distributor parts and fittings made.
Alle der bereits bekannten Rohrverbindungen erfüllen zwar das Kriterium der Dichtheit, manche auch unter Druck- und Temperaturbelastungen. Jedoch sind meistens die Herstellungskosten sehr hoch und häufig sind diese nur unter großem Zeitaufwand montierbar.All Although the already known pipe connections meet the criterion of Tightness, some even under pressure and temperature loads. however Mostly the manufacturing costs are very high and often these only under large Time can be mounted.
Die genannten bisherigen Rohrverbindungen nach dem Schiebehülsenprinzip sind erfahrungsgemäß besonders bei hohen Temperatur- und Druckschwankungen für Abrutschen des Rohres vom Grundkörper anfällig.The mentioned previous pipe connections after the sliding sleeve principle are according to experience special at high temperature and pressure fluctuations for slipping of the pipe from body susceptible.
Der Erfindung liegt die Aufgabe zugrunde, eine Rohrverbindung zu schaffen, die kostengünstig herzustellen und einfach zu montieren ist und insbesondere auch bei höheren Temperaturen und Drücken standfest und dicht ist.Of the Invention has for its object to provide a pipe connection, the inexpensive to produce and easy to assemble and especially at higher temperatures and pressing stable and tight.
Zur Lösung dieses Problems wird eine Rohrverbindung nach dem Schiebehülsenprinzip mit den Merkmalen des Patentanspruchs 1 vorgeschlagen, die am Grundkörper einen Rohranschlussabschnitt aufweist, auf welchen das anzuschließende Rohr aufgeschoben wird. Der Grundkörper der Rohrverbindung hat eine Einrastrille, in die ein Einrastzahn der Kunststoffhülse eingreift. Beide werden durch axiale Verschiebung der Schiebehülse kraftschlüssig ineinander gepresst und somit verhakt. Die Schiebehülse besteht aus zwei Teilen, nämlich einer Außenhülse aus Metall und einer Innenhülse aus Kunststoff. Die Innenhülse gewährleistet durch den Einrastzahn einen sicheren Halt der Hülse am Grundkörper, während die Metallhülse für konstanten Anpressdruck des Rohres auf den Grundkörper sorgt und der Schiebehülse mechanische Stabilität verleiht.to solution This problem is a pipe connection according to the sliding sleeve principle proposed with the features of claim 1, the base body a Pipe connection portion has, on which pushed the pipe to be connected becomes. The main body the pipe connection has a Einrastrille into which a Einrastzahn the Plastic sleeve engaging. Both are frictionally engaged with each other by axial displacement of the sliding sleeve pressed and thus hooked. The sliding sleeve consists of two parts, namely an outer sleeve Metal and an inner sleeve made of plastic. The inner sleeve guaranteed by the Einrastzahn a 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.
Zwischen Schiebehülse und Grundkörper kann ein Dichtungsring aus elastischem Material eingesetzt werden, um ein Eindringen des flüssigen oder gasförmigen Mediums zu verhindern. Dadurch kann ein Aufweiten der Schiebehülse und das Abrutschen der Rohrleitung durch den Druck des Mediums verhindert werden. Diese Verbindung ist sowohl bei Kalibrier- als auch bei Rohraufweitsystemen verwendbar.Between sliding sleeve and body can a sealing ring made of elastic material can be used to an intrusion of the liquid or gaseous Prevent media. This can cause a widening of the sliding sleeve and prevents slippage of the pipeline by the pressure of the medium become. This compound is available for both calibration and Tube expansion systems usable.
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 einiger Zeit bei häufigen und großen Temperaturschwankungen als Folge der Längenausdehnungen des Rohres und bei Multiverbundrohren wegen unterschiedlicher Ausdehnungskoeffizienten der einzelnen Schichten ein.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 some time frequent and huge Temperature fluctuations as a result of the linear expansion of the tube and multi-composite pipes because of different expansion coefficients of the individual layers.
Das System ist 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.The System is relatively easy and inexpensive to produce. Also the Assembly costs are low with this system. The installation is different hardly of the in the hitherto common Compression sleeve systems.
Die Außen- und Innenhülse bilden zusammen eine Einheit. Die äußere Metallhülse kann im Inneren eine oder mehrere Zacken haben, die das Abrutschen von der Kunststoffhülse verhindern. Der Rohranschlussabschnitt des Grundkörpers kann auf seiner Rohranliegefläche ein Sägezahnprofil aufweisen.The Outside- and inner sleeve together form a unity. The outer metal sleeve can inside have one or more prongs that slipping off the plastic sleeve prevent. The pipe connection portion of the body can on his Rohranliegefläche a sawtooth profile exhibit.
