B. aus Kunststoff, mittels einer ebenfalls aus Metall bestehenden Preßhülse, die derart ausgebildet ist, daß die Preßhülse mittels einer Preßzange oder dergl. exakt und lagegerecht positionierbar ist und diese, etwa im Bereich des Anschlages des Endbereiches des aufgeschobenen Rohres am Fittingkörper, mit mindestens einem Durchbruch versehen ist, wobei für die Abstützung der Preßzange ein umlaufender Ring an der Preßhülse vorgesehen ist.The invention relates to the connection of a fitting, for example made of metal, with a tube, e.g. Example, made of plastic, by means of a press sleeve also made of metal, which is designed such that the press sleeve can be positioned exactly and in the correct position by means of pressing tongs or the like, and this, for example in the region of the stop of the end region of the pushed-on pipe on the fitting body, with at least is provided with an opening, a circumferential ring being provided on the press sleeve for supporting the pressing tongs.
Description
Die Erfindung bezieht sich auf die Verbindung eines beispielsweise aus Metall bestehenden Fittings mit einem Rohr, z. B. aus Kunststoff, mittels einer ebenfalls beispielsweise aus Metall bestehenden Preßhülse.The invention relates to the connection of a metal, for example existing fittings with a pipe, e.g. B. made of plastic, by means of a also, for example, made of metal press sleeve.
Rohrverbindungen mittels sogen. Preßfittings sind an sich bekannt. Sie dienen zur dichten Verbindung eines Rohres mit einem Fittingkörper.Pipe connections using so-called Press fittings are known per se. You serve for the tight connection of a pipe with a fitting body.
So geht u. a. aus dem DE 90 16 310 U1 eine Rohrverbindung, insbesondere an Verbundrohren, d. h. ein sogen. Preßfitting hervor, bei dem im Rohrendbereich zwischen dem Anschlußbereich einer Stützhülse und der Preßhülse eine wellenförmige Struktur erzeugt wird, um dabei Kerbwirkungen zu vermeiden. Nachteilig dabei ist, daß die in das Preßwerkzeug eingelegte Preßhülse vom Positionierring abgleiten kann, da sie nicht fest mit dem Fittingkörper verbunden ist.So u. a. from DE 90 16 310 U1 a pipe connection, especially on composite pipes, d. H. a so-called Press fitting out, in which Pipe end area between the connection area of a support sleeve and the Press sleeve a corrugated structure is created, with notch effects to avoid. The disadvantage here is that the inserted in the press tool Press sleeve can slide off the positioning ring, since it is not firmly attached to the Fitting body is connected.
Dem DE 91 16 948 U1 ist eine ähnliche Rohrverbindung zu entnehmen, bei der zusätzlich ein Sichtfenster zur Überprüfung der Lage des Rohrendes auf seinem Anschlußbereich sitzt. Dies ist aber insofern ohne Einfluß auf die Verbindung, weil auch hierbei beim Verpressen ein Verrutschen der Preßhülse möglich ist.DE 91 16 948 U1 shows a similar pipe connection in which additionally a viewing window to check the position of the pipe end its connection area sits. However, this has no effect on the Connection, because here too, the pressing sleeve slips during pressing is possible.
Eine weitere solche Rohverbindungen ist, wie aus dem DE 295 03 019 U1 hervorgeht, zur einfachen Herstellung der Verbindung mit einer Preßhülse, die mittels eines aus Kunststoff bestehenden Halteringes in axialer Richtung am Fittingkörper unverlierbar festliegt, bekannt geworden. Auch 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.Another such raw connections is, as from DE 295 03 019 U1 emerges for the simple establishment of the connection with a compression sleeve, by means of a plastic retaining ring in the axial direction is captive on the fitting body, became known. This kind of However, connection is not free from disadvantages. So is between the press sleeve and a plastic retaining ring is connected to the fitting body. Except that with this retaining ring an additional part in the connection is introduced, there is a risk that this retaining ring by putting on the Crimping pliers, for which the retaining ring serves as a guide, from its anchoring is pressed or damaged.
Bei dem Gegenstand der US-PS 4 407 532 ist zwar eine Arretierung auf der Preßhülse vorgesehen, aber auch hier kann beim Preßvorgang die Preßhülse vom Grundkörper schräg abrutschen, was u. U. zu nicht einwandfreien Verpressungen führt.In the subject of US-PS 4 407 532 there is a lock on the Press sleeve provided, but also here the press sleeve during the pressing process slide off the base at an angle, which u. U. too impeccable Leads to pressing.
Der Erfindung, 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 überprüfbare, lagegerechte und axiale Positionierung des Preßwerkzeuges gewährleistet.The invention, as described in the claims, is therefore the Task to create a generic connection that the Avoids disadvantages of the known connections and a verifiable, correct and axial positioning of the press tool guaranteed.
Mit der Erfindung wird der Vorteil erzielt, daß einerseits das Preßwerkzeug mit Sicherheit keine Teile der Verbindung verdrücken oder beschädigen kann, es lagegerecht am Fittingkörper bzw. der Preßhülse axial positioniert ist und andererseits eine feste Angriffsfläche an den Elementen der Verbindung hat. Ein weiterer Vorteil der mit der Erfindung vorgeschlagenen Verbindung liegt darin, daß die Preßhülse auch Sichtfenster zur Kontrolle des Sitzes des zu verbindenden Kunststoffrohres auf dem Fittingkörper beinhaltet. Hinzu kommt, daß die Verbindung gem. der Erfindung einfacher und billiger in der Herstellung und bei der Montage ist.With the invention, the advantage is achieved that on the one hand the pressing tool Security cannot squeeze or damage any part of the connection to it is axially positioned correctly on the fitting body or the press sleeve and on the other hand has a fixed contact surface on the elements of the connection. Another advantage of the connection proposed by the invention lies in that the press sleeve also viewing window to control the fit of the connecting plastic pipe on the fitting body includes. Come in addition, that the connection acc. the invention easier and cheaper to manufacture and when assembling it.
Die Erfindung ist nachstehend anhand eines in den Abbildungen dargestellten Ausführungsbeispieles näher erläutert.The invention is shown below with reference to one in the figures Embodiment explained in more detail.
Es zeigt:It shows:
Fig. 1 eine Verbindung im Schnitt, Fig. 1 is a compound in section,
Fig. 2 eine Ausführungsvariante der Fig. 1, Fig. 2 shows a variant of Fig. 1,
Fig. 3 eine weitere Ausführungsvariante. Fig. 3 shows another embodiment.
Die in der Fig. 1 dargestellte Verbindung besteht im wesentlichen aus dem Fittingkörper 1, dem auf dessen rohrförmigen Abschnitt bis zum Anschlag 4 aufgeschobenen Kunststoffrohr 7 und der über dessen Ende angeordneten Preßhülse 2. Die Preßhülse 2 weist einen nach außen gewölbten Positionierring 3 für den Eingriff eines Preßwerkzeuges auf, das im Bereich dieses Positionierringes 3 eine entsprechende Negativform aufweist. Die Preßhülse 2 ist außerdem mit einem oder mehreren als Sichtfenster 6 dienenden Durchbrüchen in der Nähe des Endes des mit dem Fittingkörper 1 zu verbindenden Rohres 7 versehen. Diese Sichtfenster 6 können entweder im Bereich des Positionierringes 3 oder darunter, wie in Fig. 2 dargestellt, vorgesehen sein, wobei der Positionierring 3 keinerlei Durchbrüche aufweist.The connection shown in FIG. 1 essentially consists of the fitting body 1 , the plastic tube 7 pushed onto its tubular section up to the stop 4 and the press sleeve 2 arranged over its end. The press sleeve 2 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 3 . The compression sleeve 2 is also provided with one or more openings serving as viewing windows 6 near the end of the pipe 7 to be connected to the fitting body 1 . These viewing windows 6 can either be provided in the area of the positioning ring 3 or below, as shown in FIG. 2, the positioning ring 3 having no openings.
In der Fig. 3 ist zwischen dem Fittingkörper 1 und der Preßhülse 2 ein O-Ring 9 angeordnet, der in den Positionierring 11 am Ende der Preßhülse 10 gelegt und in einer Hinterschneidung 1a des Fittingkörpers gelagert ist. Sein Durchmesser ist dabei größer gewählt, als der kleinste Durchmesser der Preßhülse 10, so daß zwischen dieser und dem Fittingkörper 1 ein geringer Abstand verbleibt, beide also gegeneinander galvanisch getrennt sind. In Fig. 3, an O-ring 9 is arranged between the fitting body 1 and the compression sleeve 2 , which is placed in the positioning ring 11 at the end of the compression sleeve 10 and is mounted in an undercut 1 a of the fitting body. Its diameter is chosen larger than the smallest diameter of the compression sleeve 10 , so that there is a small distance between it and the fitting body 1 , both of which are therefore galvanically isolated from one another.
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 Fittingkörper 1 mit einer solchen Schutzschicht überzogen sein oder aus einem neutralen Material, beispielsweise Keramik bestehen. The compression sleeve 2 can, for example, be provided with a coating of plastic, ceramic or the like at least at its end facing the fitting body 1 in order to prevent corrosion in the end region and on the fitting body. Of course, the fitting body 1 can also be coated with such a protective layer or consist of a neutral material, for example ceramic.
