BESCHREIBUNG:DESCRIPTION:
Press- / Quetschfitting-Stützhülse m. manschettenförmigerPress / compression fitting support sleeve with cuff-shaped
ProfildichtungProfile seal
Die Erfindung ist dem Bereich Rohrverbindungen zuzuordnen und betrifft eine am Fitting angeformte Stützhülse auf welcher eine oder mehrere manschettenförmige Profildichtung/en in dafür vorgesehene Ausfräsung/en eingebracht sind, zur Abdichtung der Press - oder Quetschfit tinge in Verbindung mit Metall, Kunststoff,- und VerbundrohrenThe invention is assigned to the field of pipe connections and relates to a support sleeve formed on the fitting on which one or more sleeve-shaped profile seals are inserted into the milled recess(es) provided for this purpose, for sealing the press or squeeze fittings in connection with metal, plastic and composite pipes.
Die Profildichtung ist mit der glatten Unterseite in die aus = gefräste Nut eingelassen. Die Oberseite der Profildichtung weist eine oder mehrere radial umlaufende Profilierungen auf, welche bei Überschieben des Rohres vor der eigentlichen Verpressung durch die Gestaltung der Profilierung schon eine Kompression bewirken.The profile seal is set into the milled groove with its smooth underside. The top of the profile seal has one or more radially circumferential profiles, which, when pushed over the pipe before the actual pressing, cause compression due to the design of the profile.
Das auf die Stützhülse und somit über die Profildichtung geschobene Rohrende wird durch Pressung oder Quetschung auf die Profildichtung gedrückt, wobei durch die starke Kompression die Rohrverbindung dauerhaft abgedichtet wird.The pipe end pushed onto the support sleeve and thus over the profile seal is pressed onto the profile seal by pressing or squeezing, whereby the strong compression permanently seals the pipe connection.
Es sind bereits Verbindungen für Rohre mit Press-u. Quetschfittingen bekannt, bei welchen die Abdichtung durch eine in einen Ring-Nut eingelegten, dünnen O-Ring erfolgt, sowie eine dreieckige, keilförmige Abdichtung; ebenfalls in einen Ring-Nut eingelegt.Connections for pipes with press and compression fittings are already known, in which the seal is made by a thin O-ring inserted into a ring groove, as well as a triangular, wedge-shaped seal; also inserted into a ring groove.
Die Aufgabe der Erfindung besteht darin, die Press-und Quetsch-Rohr = verbindungen so zu verbessern, daßThe object of the invention is to improve the press and squeeze pipe connections so that
die auf den Fitting aufgeschobenen Rohre zuverlässig und dauerhaft abgedichtet werden,the pipes pushed onto the fitting are reliably and permanently sealed,
eine höhere Kompression der Dichtung unda higher compression of the seal and
eine gleichmäßigere Druckverteilung in der Abdichtung bewirkt wird,a more even pressure distribution in the seal is achieved ,
die Gefahr des Eindringens von Unreinheiten in den Dichtungs= sitz verhindert wird,the risk of impurities penetrating the seal seat is prevented,
Undichtheiten durch leichte Verletzungen der Abdichtung vermieden werden.Leaks can be avoided due to minor damage to the seal.
Diese Aufgaben werden durch die im Patentanspruch angegebene Erfindung gelöst.These objects are solved by the invention specified in the patent claim.

Die Vorteile einer Stützhülse mit eingelassener/n, gemäß der Erfindung gestalteter/n Profildichtung/en liegen im einzelnen darin:The advantages of a support sleeve with embedded profile seal(s) designed according to the invention are as follows:
- Durch Aufschieben des angefasten Rohrendes (1) auf die Fitting-Stützhülse (2), welche mit der Profildichtung (3) versehen ist, wird die zuerst überschobene Seite der Dichtung niedergehalten,(4) während gleichzeitig die an der Oberseite befindliche/n Verdick= ung/en abwärts gedrückt wird/werden.- By pushing the chamfered pipe end (1) onto the fitting support sleeve (2), which is provided with the profile seal (3), the side of the seal that is pushed over first is held down (4), while at the same time the thickening(s) on the top is/are pressed downwards.
Durch die beginnende Kompression innerhalb der Profildichtung (5) { unterhalb der Verdickung ) wird ein Verschieben oder Verdrehen der Dichtung verhindert.The initial compression within the profile seal (5) { below the thickening ) prevents the seal from shifting or twisting.
- Der Kompressionsdruck ist im Bereich der niedergedrückten Verdick= ung größer, sodaß der davon abgehende Druck auf Boden - und Seiten= flächen der Dichtung wirkt.- The compression pressure is greater in the area of the depressed thickening, so that the pressure arising from this acts on the bottom and side surfaces of the seal.
Bei Verpressung resp. Verquetschung des übergeschobenen Rohrendes wird zusätzlicher Druck auf die Profildichtung ausgeübt, was zu einer höheren, dauerhaft druckfesten und gleichmäßigen Verdichtung führt. (6)When the pipe end is pressed or squeezed, additional pressure is exerted on the profile seal, which leads to a higher, permanently pressure-resistant and uniform compaction. (6)
Die bekannten O-Ring-Dichtungen lassen aufgrund ihrer Rundschnurform zuviel Freiräume in den winkligen Ausfräsungen, wodurch nur wenig Kompression erzeugt wird.Due to their round cord shape, the well-known O-ring seals leave too much free space in the angled cutouts, which means that only little compression is generated.
- durch die fest eingelegte Profildichtung können keine Unreinheiten wie Sand, Staub, Späne in die Ausfräsung gelangen, was bei O-Ring-Dichtungen kaum zu vermeiden ist. Solche Partikel - womit im Praxisbetrieb auf Baustellen immer gerechnet werden muß - führen zur Verletzung der Dichtung beim Einschieben des Rohrendes und somit zu Undichtheiten.- The firmly inserted profile seal means that no impurities such as sand, dust, chips can get into the cutout, which is almost impossible to avoid with O-ring seals. Such particles - which must always be expected in practical operation on construction sites - lead to damage to the seal when the pipe end is pushed in and thus leaks.
- aufgrund des erfindungsgemäßen Aufbaues erfolgt eine sichere, gleich= mäßige Druckverteilung innerhalb der Profildichtung, wie sie z.B. bei einer Keil- / Konusdichtung nie gegeben ist.- Due to the inventive design, a safe, even pressure distribution occurs within the profile seal, which is never the case with a wedge/cone seal, for example.
- eine - auch leichte - oberflächliche Verletzung eines Rundschnurringes bzw. 0 - Ringes führt, wie die Praxis oft zeigt, nach kürzerer oder längerer Zeit zu Undichtheiten.- a superficial injury to a round cord ring or 0-ring - even a slight one - often leads to leaks after a shorter or longer period of time, as practice often shows.
Die breite und große Oberfläche der gemäß der Erfindung gestalteten Profildichtung verträgt kleine Verletzungen ohne Gefahr späterer Undichtheiten.The wide and large surface of the profile seal designed according to the invention tolerates small injuries without the risk of subsequent leaks.
