Abstract

Sealing system for bores, e.g. in the ends of pipes (23), comprises a bung (21) with a central bore which fits into a tubular sealing sleeve (22). The sleeve has an annular rib (6) near the base of its inner surface. This fits into a groove (26) on the outside of the bung, near its base, when the bung is partially inserted and into a second groove (25) above it when the bung is completely inserted.

Description

Die Erfindung betrifft eine Vielzweck-Dichtung für eine unidirektionale Anordnung, die, wenn über einem Stopfen montiert, eine geringe Kraft benötigt, um den Stopfen in einer Bohrung zu installieren, und eine große Kraft benötigt, um den Stopfen aus der Bohrung zu entfernen.The Invention relates to a multi-purpose seal for a unidirectional arrangement, the when over a plug mounted, a small force needed to plug in one Bore to install, and a large force needed to remove the plug from the hole.

Der Zweck dieser Dichtung ist,

  • – dass nur eine geringe Kraft benötigt wird, um einen Stopfen und eine Dichtungsanordnung in einer Bohrung zu installieren;
  • – dass eine große Kraft benötigt wird, um den Stopfen aus der Bohrung zu entfernen;
  • – dass eine stabile Verbindung zwischen Bohrung und Stopfen, der in der Bohrung installiert ist, gewährleistet wird;
  • – dass eine ausreichende Dichtwirkung zwischen beiden Komponenten gewährleistet wird;
  • – dass die Montage der Dichtung auf dem Stopfen einfach erfolgen kann;
  • – dass ein möglicherweise riesiger Toleranzbereich der Dicke der Wand, in der sich die Bohrung befindet, kompensiert werden kann.
The purpose of this seal is
  • - That only a small force is needed to install a plug and a seal assembly in a hole;
  • - That a large force is needed to remove the plug from the bore;
  • - That a stable connection between the hole and plug, which is installed in the hole, is ensured;
  • - That a sufficient sealing effect between the two components is ensured;
  • - That the mounting of the seal on the plug can be done easily;
  • - That a possibly huge tolerance range of the thickness of the wall, in which the bore is located, can be compensated.

Beschreibung der erfindungsgemäßen Dichtung (vgl. 1a, 1b, 1c)Description of the seal according to the invention (cf. 1a . 1b . 1c )

Die Dichtung 1 ist im Wesentlichen zylindrisch. Sie ist bevorzugt aus einem elastischen Material, etwa Gummi, gefertigt.The seal 1 is essentially cylindrical. It is preferably made of an elastic material, such as rubber.

An der Oberseite ist ein Kopfteil 2, um zu verhindern, dass die Dichtung in die Bohrung verrutscht, wenn der Stopfen in die Bohrung gepresst wird. Dazu hat das Kopfteil bevorzugt einen größeren Durchmesser als die Bohrung. Dichtungsringe 3 sind an der oberen Außendurchmesser-Seite angeordnet, um die Dichtwirkung zur Bohrung zu gewährleisten.At the top is a headboard 2 to prevent the gasket from slipping into the hole when the plug is pressed into the hole. For this purpose, the head part preferably has a larger diameter than the bore. seals 3 are arranged on the upper outer diameter side to ensure the sealing effect to the bore.

Dichtungsringe 4 sind an der Innendurchmesser-Seite angeordnet, um die Dichtwirkung zum Stopfen zu gewährleisten.seals 4 are arranged on the inner diameter side to ensure the sealing effect for plugging.

Sicherungsringe 5 sind an unteren Außendurchmesser-Seite angeordnet, um den Widerstand zu gewährleisten, wenn der Stopfen aus der Bohrung freigelassen wird.Retaining rings 5 are located on the lower outside diameter side to ensure resistance when the plug is released from the bore.

Ein innerer Zahn bzw. eine innere Stufe 6 gestattet der Dichtung in einer gewünschten Position über dem Stopfen einzurasten, während die Dichtung auf dem Stopfen montiert wird und während Stopfen und Dichtung in die Bohrung gepresst werden. Die Form des Zahns bzw. der Stufe gestattet der Dichtung, über den Stopfen zu rutschen, einzurasten, und den Außendurchmesser der Dichtung im unteren Bereich (Fußbereich) zu vergrößern. Weiterhin verhindert die Form der Dichtung, dass die Dichtung über den Stopfen gleitet, und die Form der Dichtung gewährleistet ausreichend Widerstand, wenn eine Kraft auf den Stopfen ausgeübt wird, um ihn aus der Bohrung loszumachen.An inner tooth or inner stage 6 allows the seal to lock in a desired position over the plug while mounting the seal on the plug and while pushing the plug and seal into the bore. The shape of the tooth or step allows the seal to slip over the plug, lock in place, and increase the outer diameter of the seal in the lower region (foot area). Furthermore, the shape of the seal prevents the seal from sliding over the plug, and the shape of the seal provides sufficient resistance when a force is applied to the plug to release it from the bore.

Ein axialer Schnitt 7, maschinell eingebracht oder geformt, an der Unterseite der Dichtung, gestattet es der Dichtung sich zu öffnen, wenn sie über den Stopfen gleitet, wodurch die anzuwendende Kraft bei der Installation der Dichtung auf dem Stopfen reduziert wird. Der Schnitt gestattet es auch der Unterseite (dem Fuß) der Dichtung sich zu öffnen, wenn der Stopfen und die Dichtung in die Bohrung gepresst werden, und der Schnitt gestattet es auch, dass die Dichtung den Außendurchmesser vergrößert in einer Weise, dass der angewandten Kraft zum Herauslösen des Stopfens aus der Bohrung richtig Widerstand geleistet wird.An axial cut 7 machined or molded on the underside of the seal, allows the seal to open as it slides over the plug, reducing the force to be applied when installing the seal on the plug. The cut also allows the bottom (foot) of the gasket to open when the plug and gasket are pressed into the bore, and the cut also allows the gasket to increase in outside diameter in such a manner as to exert the applied force Resistance is properly provided for the removal of the plug from the bore.

Funktionsbeschreibung (vgl. 2A, 2B, 2C, 2D)Functional description (cf. 2A . 2 B . 2C . 2D )

2A2A

Alle Komponenten (Stopfen 21, Dichtung 22, Bohrung 23) sind vor dem Zusammenbau gezeigt.All components (plug 21 , Poetry 22 , Drilling 23 ) are shown before assembly.

2B2 B

Die Dichtung ist auf dem Stopfen installiert. Der innere Zahn/die innere Stufe schnappt an der ersten Aussparung am Stopfen ein.The Seal is installed on the plug. The inner tooth / inner Stage snaps to the first recess on the plug.

2C2C

Die Stopfen- und Dichtungs-Anordnung wird in die Bohrung gepresst, bis das Kopfteil der Dichtung mit der Außenseite (der oberen Kante) der Bohrung in Kontakt kommt. In dieser Position wirken die beiden Dichtungsringe radial auf die Bohrung.The Plug and seal assembly is pressed into the hole until the head part of the seal with the outside (the upper edge) the bore comes into contact. In this position, the two act Seal rings radially on the hole.

2D2D

Der Stopfen wird endgültig (vollständig) in die Bohrung (und in die Dichtung) gepresst. Dabei verbleibt die Dichtung in der gleichen Position (relativ zur Bohrung) wie in der vorherigen 2C, denn der Kopfteil leistet Widerstand und der Stopfen gleitet in die Dichtung hinein. Der innere Zahn/die innere Stufe öffnet sich aufgrund des axialen Schnitts und der Form des Stopfens, und der innere Zahn/die innere Stufe rastet in die obere Aussparung. Der Stopfendurchmesser an der oberen Aussparung hat einen solchen Durchmesser, der den Zahn/die Stufe zwingt, die Unterseite der Dichtung offen (gespreizt) zu halten.The plug is finally (completely) pressed into the hole (and into the seal). The seal remains in the same position (relative to the hole) as in the previous one 2C because the headboard provides resistance and the plug slides into the seal. The inner tooth / inner stage opens due to the axial cut and the shape of the plug, and the inner tooth / inner stage snaps into the upper recess. The plug diameter at the top recess has a diameter which forces the tooth / step to keep the bottom of the seal open (spread).

Zusammenfassend lehrt die Erfindung,

  • – dass die Dichtwirkung auf die Bohrungsoberfläche bewirkt wird durch Ringe an der oberen Seite der Dichtung, und die Dichtwirkung auf die Stopfenoberfläche bewirkt wird durch Ringe am Innendurchmesser der Dichtung;
  • – dass die Sicherungswirkung (d.h. die Eigenschaft, die es dem Stopfen nicht gestattet, leicht herausgezogen zu werden) durch die Ringe unten an der Dichtung am Außendurchmesser bewirkt wird, wobei diese Ringe der Innenoberfläche (der unteren Kante) der Bohrung entgegenwirken, während der untere Teil der Dichtung sich öffnet aufgrund eines axialen Schnitts und durch den inneren Zahn/die innere Stufe (an der Innenoberfläche), die auf die obere Vertiefung des Stopfens wirkt.
In summary, the invention teaches
  • - That the sealing effect on the bore surface is effected by rings on the upper side of the seal, and the sealing effect on the plug surface is effected by rings on the inner diameter of the seal;
  • - That the securing effect (ie the property that does not allow the stopper to be easily pulled out) is effected by the rings at the bottom of the seal at the outer diameter, these rings counteract the inner surface (the lower edge) of the bore, while the lower Part of the seal opens due to an axial cut and through the inner tooth / inner step (on the inner surface) which acts on the upper recess of the plug.

Die vorliegende Erfindung umfasst sowohl die vorbeschriebene Dichtung in Alleinstellung, als auch die vorbeschriebene Dichtungsanordnung umfassend einen Stopfen und eine Dichtung.The present invention includes both the above-described seal in isolation, as well as the above-described seal arrangement comprising a plug and a seal.
