Description
Hochdruckschlauchkupplung Die Erfindung bezieht sich auf solche Schlauchkupplungen, die vornehmlich für .die Weiterleitung solcher Medien benutzt werden, die unter hohem Druck stehen, und betrifft eine Kupplung, bei der das Schlaucherde über einen Nippel .gezogen ist und unter Zwischenlage .eines Drahtwendels durch einen überwurfmutterartigen Körper mit einer Schrägfläche in einer ringartigen Eindrehung des Nippels festgeklemmt wird. Bei diesen Schlauchkupplungen besteht bei höheren Drükken die Gefahr, daß der Schlauch vom Nippel abgleitet, weil er nur durch Reibung auf demselben gehalten wird und insbesondere dann, wenn es sich um Förderung von Schmiermitteln und ähnlichen viscosen Stoffen handelt, diese Reibung stark herabgesetzt wird. Durch stärkeres Anziehen der Überwurfmutter kann zwar ein stärkeres Anpressen des Drahtwendels gegen den Gummischlauch erzielt werden, doch besteht dabei die Gefahr, daß der sich mit der Ü berwurfmutter drehende Drahtwendel in den Schlauch einschneidet und diesen beschädigt.High pressure hose coupling The invention relates to such hose couplings, which are primarily used for the forwarding of such media that are listed under are high pressure, and concerns a coupling in which the hose earth via a Nipple. Is pulled and under the interposition of a wire helix through a union nut-like Body clamped with an inclined surface in a ring-like recess of the nipple will. With these hose couplings there is a risk at higher pressures that the hose slips off the nipple because it is held on it only by friction and especially when it comes to conveying lubricants and the like viscous substances, this friction is greatly reduced. By stronger Tightening the union nut can counteract a stronger pressing of the wire helix the rubber hose can be achieved, but there is a risk that the with the union nut cuts the rotating wire spiral into the hose and this damaged.
Gemäß der Erfindung ist zur Kraft- bzw. Bewegungsübertragung zwischen dem Überwurf und dem Drahtwendel ein loser Ring mit einer konischen Fläche vorgesehen, wobei ein ringförmiger Ansatz an der Schulterdes Nippelkopfes .den Drahtwendel gegen axiale Verschiebung sichert, so daß dieser sich nicht dreht, sondern nur mehr oder weniger stark zusammengepreßt wird. Infolgedessen gleitet der Ring nicht auf dem Schlauch und kann diesen nicht beschädigen. Da mehrere Drahtwindungen gleichzeitig den Preßdruck auf den Schlauch ausüben und dieser radial .auf die Schlauchmitte gerichtet ist, werden Beschädgungen des Schlauches vermieden.According to the invention, for power or motion transmission between A loose ring with a conical surface is provided for the sleeve and the wire coil, with an annular shoulder on the shoulder of the nipple head against the wire coil axial displacement ensures that it does not rotate, but only more or is less strongly compressed. As a result, the ring will not slide on the Hose and cannot damage it. Since several turns of wire at the same time Apply the pressure to the hose and apply it radially to the center of the hose is directed, damage to the hose is avoided.
Die Erfindung ist in der beigefügten Zeichnung in einem Ausführungsbeispiel dargestellt. Es zeigen Abb. z und a ,die Kupplung eines Hochdruckschlauches in zwei Stellungen und Abb.3 eine abgewandelte Ausführungsform.The invention is shown in the accompanying drawings in one embodiment shown. Fig. Z and a show the coupling of a high pressure hose in two Positions and Fig.3 a modified embodiment.
An der Verschraubung a befindet sich der Nippel b, der in der Nähe der Schulter c eine ringförmige Ausnehmung d und an der Schulter selbst einen kragenförmigen Vorsprung e hat. Über den Nippel b ist der Hochdruckschlauch f derart gezogen, daß sein Ende etwa an der Schulter des Nippels liegt. In der Höhe der Aussparung d ist nun um .den Schlauch in Drahtwendel ä in mehreren Windungen gelegt. Der Drahtwendel liegt auf der schrägen Fläche des Ringes h auf. Eine Überwurfmutter i .zieht diesen Ring lr auf die Schulterfläche c des Nippels.The nipple b is located on the screw connection a and has an annular recess d near the shoulder c and a collar-shaped projection e on the shoulder itself. The high-pressure hose f is pulled over the nipple b in such a way that its end lies approximately on the shoulder of the nipple. At the height of the recess d, the hose is now laid in several turns in a wire helix. The wire helix rests on the inclined surface of the ring h. A union nut i. Pulls this ring lr onto the shoulder surface c of the nipple.
Wenn nach dem Zusammenfügen der Teile ,der Kupplung die Überwurfmutter i gedreht wird, dann verschiebt diese den Ring 1c in axialer Richtung. Da nun einerseits die Wendelfeder g auf einer Schrägfläche dieses Ringes h. aufliegt und andererseits gegen eine axiale Bewegung durch den Kragen e gehindert ist. wird sie durch die Bewegung des Ringes h in radialer Richtung zusammengepreßt und drückt das Schlauchende in die Ausnehmung d hinein.If after joining the parts, the coupling the union nut i is rotated, then this moves the ring 1c in the axial direction. There now on the one hand the helical spring g on an inclined surface of this ring h. and on the other hand is prevented from axial movement by the collar e. is it through the Movement of the ring h is compressed in the radial direction and presses the end of the hose into the recess d.
Bei der Ausbildung nach Abb. 3 ist zwischen .dem Ring h und der Schulter c des Nippels a ein zweiter Ring 111 angeordnet, auf dessen Schrägfläche ein weiterer Drahtwendel gi liegt. Der Ring lt, ist hierbei mit einer Schulter ho für den Drahtwendel g versehen.In the embodiment according to Fig. 3, a second ring 111 is arranged between .the ring h and the shoulder c of the nipple a, on the inclined surface of which a further wire helix gi lies. The ring lt is here provided with a shoulder ho for the wire helix g.
