Description
Die Neuerung bezieht sich auf die Verbindung eines beispielsweise aus Metall bestehenden Fittings mit einem Rohr, z.B. aus Kunststoff, mittels einer ebenfalls beispielsweise aus Metall besteheneden Preßhülse. The innovation relates to the connection of a fitting, e.g. made of metal, with a pipe, e.g. made of plastic, by means of a press sleeve, also made of metal, for example.
Solche Verbindungen mittels sogen. Preßfittings sind an sich bekannt. Sie dienen zur dichten Verbindung eines Rohres mit einem Fittingkörper und sind, wie aus dem DE-GM 295 03 019.4 U1 hervorgeht, zur einfachen Herstellung der Verbindung mit einer Preßhülse, die mittels eines aus Kunststoff bestehenden Halteringes in axialer Richtung am Fittingkörper unverlierbar festgelegt.Such connections using so-called press fittings are known per se. They are used to tightly connect a pipe to a fitting body and, as can be seen from DE-GM 295 03 019.4 U1, are used to simply create the connection with a press sleeve, which is fixed in place in the axial direction to the fitting body by means of a plastic retaining ring.
Eine weitere Verbindung diesr Art offenbart das DE-GM 90 16 310. Dabei sind die Presshülsen als plastisch umformbare Pressglieder ausgebildet. Vor und während des Pressvorganges können sich die Presshülsen jedoch unkontrolliert verschieben, was zu unbrauchbaren Verbindungen führt.Another connection of this type is disclosed in DE-GM 90 16 310. The press sleeves are designed as plastically deformable press members. Before and during the pressing process, however, the press sleeves can shift uncontrollably, which leads to unusable connections.
Diese Art der Verbindung ist jedoch nicht frei von Nachteilen. So ist zwischen der Preßhülse und dem Fittingkörper ein Haltering aus Kunststoff geschaltet. Abgesehen davon, daß mit diesem Haltering ein zusätzliches Teil in die Verbindung eingeführt ist, besteht die Gefahr, daß dieser Haltering durch das Anlegen der Preßzange, für die der Haltering als Führung dient, aus seiner Verankerung gedrückt oder beschädigt wird.However, this type of connection is not without disadvantages. For example, a plastic retaining ring is inserted between the press sleeve and the fitting body. Apart from the fact that this retaining ring introduces an additional part into the connection, there is a risk that this retaining ring will be pushed out of its anchorage or damaged by the application of the pressing pliers, for which the retaining ring serves as a guide.
Der Neuerung, wie sie in den Ansprüchen beschrieben ist, liegt daher die Aufgabe zugrunde, eine gattungsgemäße Verbindung zu schaffen, die die Nachteile der bekannten Verbindungen vermeidet und eine lagegerechte, axiale Positionierung des Preßwerkzeuges gewährleistet.The innovation, as described in the claims, is therefore based on the task of creating a generic connection that avoids the disadvantages of the known connections and ensures a correct, axial positioning of the pressing tool.
Mit der Neuerung wird der Vorteil erzielt, daß einerseits das Preßwerkzeug mit Sicherheit keine Teile der Verbindung verdrücken oder beschädigen kann, es lagegerecht am Fittingkörper bzw. der PreßhülseThe innovation has the advantage that, on the one hand, the pressing tool cannot crush or damage any parts of the connection, it is correctly positioned on the fitting body or the pressing sleeve

axial positioniert ist und andererseits eine feste Angriffsfläche an den Elementen der Verbindung hat. Ein weiterer Vorteil der mit der Neuerung vorgeschlagenen Verbindung liegt darin, daß die Preßhülse auch Sichtfenster zur Kontrolle des Sitzes des zu verbindenden Kunststoffrohres auf dem Fittingkörper beinhaltet. Hinzukommt, daß die Verbindung gem. der Neuerung einfacher und billiger in der Herstellung und bei der Montage ist.is positioned axially and on the other hand has a fixed contact surface on the elements of the connection. A further advantage of the connection proposed with the innovation is that the press sleeve also contains a viewing window for checking the fit of the plastic pipe to be connected on the fitting body. In addition, the connection according to the innovation is simpler and cheaper to manufacture and assemble.
Die Neuerung ist nachstehend anhand eines in den Abbildungen dargestellten Ausführungsbeispieles näher erläutert.The innovation is explained in more detail below using an example shown in the figures.
Die Figur zeigt eine neuerungsgemäße Verbindung im Schnitt.The figure shows a cross-section of a new connection.
Die in Fig. 1 dargestellte Verbindung besteht im wesentlichen aus dem Fittingkörper 1, dem auf dessen rohrförmigen Abschnitt bis zum Anschlag 4 aufgeschobenen Kunststoffrohr 6 und der über dessen Ende angeordneten Preßhülse 2. Der Fittingkörper 1 weist einen nach außen gewölbten Positionierring 3 für den Eingriff eines Preßwerkzeuges auf, daß im Bereich dieses Positionierringes eine entsprechende Negativform aufweist. Unterhalb des Positionierringes 3 ist ein Anschlag 4 vorgesehen, der, wie aus der Abbildung ersichtlich, am Übergang zum Positionierring 3 eine geringere Hinterschneidung aufweist, in die die Presshülse einschnappt und somit für den Pressvorgang unverrückbar festgelegt ist.The connection shown in Fig. 1 consists essentially of the fitting body 1, the plastic pipe 6 pushed onto its tubular section up to the stop 4 and the press sleeve 2 arranged over its end. The fitting body 1 has an outwardly curved positioning ring 3 for the engagement of a pressing tool, which has a corresponding negative shape in the area of this positioning ring. A stop 4 is provided below the positioning ring 3, which, as can be seen from the illustration, has a smaller undercut at the transition to the positioning ring 3, into which the press sleeve snaps and is thus immovably fixed for the pressing process.
Die Preßhülse 2 ist außerdem mit einem oder mehreren als Sichtfenster 5 dienenden Durchbrüchen in der Nähe des Endes des mit dem Fittingkörper 1 zu verbindenden Rohres 6 versehen. Diese Sichtfenster 5 können im Bereich des Positionierringes 3 oder darunter sein. Die Sichtfenster 5 der Preßhülse können z.B. auch als Schlitze am Ende derselben vorgesehen sein.The press sleeve 2 is also provided with one or more openings serving as viewing windows 5 near the end of the pipe 6 to be connected to the fitting body 1. These viewing windows 5 can be in the area of the positioning ring 3 or below it. The viewing windows 5 of the press sleeve can also be provided, for example, as slots at the end of the same.
Die Preßhülse 2 kann beispielsweise zumindest an ihrem dem Fittingkörper 1 zugekehrten Ende mit einem Überzug aus Kunststoff, Keramik oder dergl. versehen sein, um eine Korrosion im Endbereich und am Fittingkörper zu verhindern. Selbstverständlich kann auch der Fitting-The press sleeve 2 can, for example, be provided with a coating made of plastic, ceramic or the like at least at its end facing the fitting body 1 in order to prevent corrosion in the end area and on the fitting body. Of course, the fitting
