Abstract

The connector has a pipe seat with dimensions of a pipe attached at an inner side of the connector with a clearance fit, where the pipe is inserted into the pipe seat and does not moved in an axial direction. The pipe seat has a chamfer for facilitating insertion of the pipe. An indentation (2) is arranged in the inner side of the connector, and accommodates an elastomer sealing ring that absorbs vibrations. Two cutting edges (3) are attached in front of and on a contour for the sealing ring for sealing connection of the pipe seat and pipe for range of high pressures. The connector is formed in shapes of linear, angular, t- or cruciform.

Description

Handelsübliche Pressfittings – wie von den Firmen Mapress Geberit, Raccorderie Metalliche oder Viegener hergestellt – dienen dem Zweck, Rohrleitungen, die einen Betriebsdruck von 16 Bar nicht überschreiten, miteinander zu verbinden. Die Verpressung der sogenannten Pressfittings erfolgt mit Hilfe von elektromechanischen Pressgeräten (u. A. von den Firmen Novopress, Klauke, ... erhältlich). Die Dichtigkeit wird durch einen ringförmigen Elastomer erzielt, der den Hohlraum zwischen Rohr und Fitting verschließt. Der Nachteil der Pressfittings ist der verhältnismäßig niedrige Druck, bei dem eine Dichtigkeit der Verbindung garantiert wird.Commercially available press fittings - manufactured by the companies Mapress Geberit, Raccorderie Metalliche or Viegener - serve the purpose of connecting pipes that do not exceed an operating pressure of 16 bar. The pressing of the so-called press fittings is carried out with the help of electromechanical pressing devices (inter alia, from the companies Novopress, Klauke, ... available). The tightness is achieved by an annular elastomer, which closes the cavity between the pipe and fitting. The disadvantage of the press fittings is the relatively low pressure at which a tightness of the connection is guaranteed.

Um Rohrleitungen mit höheren Drücken zu verbinden, werden üblicherweise Schneidringverschraubungen – wie von der Firma Parker Ermeto hergestellt – verwendet. Diese Verschraubungen erhalten ihre Funktionalität durch das Einschneiden des Schneidrings in das entsprechende Rohr beim manuellen Anziehen der Überwurfmutter. Der Nachteil der Schneidringverschraubung ist der durch die Mehrteiligkeit bedingte höhere Anschaffungspreis, sowie die aufwendige Montage.In order to connect pipes with higher pressures, usually cutting ring fittings - as manufactured by the company Parker Ermeto - used. These fittings get their functionality by cutting the cutting ring in the corresponding tube when manually tightening the nut. The disadvantage of the cutting ring fitting is the higher purchase price due to the multi-part design, as well as the complex assembly.

Der Hochdruckpressfitting-Anschluss verfügt im Wesentlichen über die Kombination folgender technischer Details:

  • 1. Eine Sicke, deren Innenkontur auf das Maß eines entsprechenden Elastomers aus Viton (O-Ring) und deren Außenkontur auf die handelsüblichen Pressgeräte angepasst ist.
  • 2. Zwei Schneidkanten, die jeweils kurz vor und kurz nach der Sicke angebracht sind. Diese schneiden beim Verpressen in das Rohr ein und sorgen für eine Arretierung.
  • 3. Einen auf das entsprechende Rohr angepassten Rohrsitz, der mithilfe einer kleinen Fase zu Beginn des Sitzes das Rohr an die richtige Stelle führt. Der Rohrsitz sorgt außerdem für zusätzliche Stabilität der Verbindung bei hohen Drücken.
  • 4. Der Viton-O-Ring, der in verpresstem Zustand für Dichtigkeit sorgt.
The high pressure press fitting connection essentially has the combination of the following technical details:
  • 1. A bead whose inner contour is adapted to the dimension of a corresponding elastomer made of Viton (O-ring) and its outer contour on the commercial pressing devices.
  • 2. Two cutting edges, each placed just before and just after the bead. These intersect during pressing into the tube and ensure locking.
  • 3. A pipe seat adapted to the corresponding pipe, which uses a small chamfer at the beginning of the seat to guide the pipe to the right place. The tube seat also provides additional stability of the connection at high pressures.
  • 4. The Viton O-ring, which ensures tightness in the compressed state.

Durch die Kombination dieser technischen Details stellt der Hochdruckpressfitting eine nicht wieder lösbare, einteilige, günstige, einfach mit handelsüblichen Werkzeugen zu montierende Rohverbindung dar, die im Hochdruckbereich sowohl in der Industrie, als auch im Sanitärbereich verwendet werden kann.By combining these technical details, the high-pressure press fitting represents a non-detachable, one-piece, low-cost, easy-to-install raw connection, which can be used in the high-pressure sector both in industry and in the sanitary sector.

Claims (3)

Pressfittinganschluss aus Edelstahl oder Stahl, in Formen von geraden, winkligen, t- oder kreuzförmigen Fittings, die über eine Rohrpassung (1) verfügen, dadurch gekennzeichnet, dass an der Innenseite des Anschlusses ein Rohrsitz mit den Abmaßen des Rohres zuzüglich einer Spielpassung angebracht ist, in welchen das eingeschobene Rohr eingeführt wird und dadurch in axialer Richtung nicht mehr verschoben werden kann. Der Rohrsitz verfügt über eine Fase, die das einführen des Rohres erleichtert.Press fitting connection made of stainless steel or steel, in forms of straight, angled, t- or cross-shaped fittings, which are fitted with a pipe fitting ( 1 ), characterized in that on the inside of the connection a pipe seat with the dimensions of the tube plus a clearance fit is mounted, in which the inserted tube is inserted and thereby can not be moved in the axial direction. The pipe seat has a chamfer, which facilitates the insertion of the pipe. Pressfittinganschluß nach Anspruch 1, dadurch gekennzeichnet, dass in der Innenseite eine Einwölbung (2) besteht, die Platz für einen elastomeren Dichtring bietet, der zum einen abdichtet und zum anderen Vibrationen, die zum Lösen der Verbindung beitragen könnten, abfedert.Pressfitting connection according to claim 1, characterized in that in the inside an indentation ( 2 ), which provides space for an elastomeric sealing ring, which seals on the one hand and, on the other hand, absorbs vibrations which could contribute to the release of the connection. Pressfittinganschluss nach einem der vorgehenden Ansprüche, dadurch gekennzeichnet, dass vor und nach der Kontur für den Dichtring zwei Schneidkanten (3) angebracht sind, die beim Verpressen des Fittings in die Außenseite des Rohres einschneiden und die Verbindung somit für Bereiche hohen Drucks abdichten.Press fitting connection according to one of the preceding claims, characterized in that before and after the contour for the sealing ring two cutting edges ( 3 ) are fitted, which cut when pressing the fitting into the outside of the tube and thus seal the connection for areas of high pressure.
