Description

Die bisherigen metallenen Rohrkupplungen zur Verbindung der Dampf- oder Luftleitungen von Eisenbahnfahrzeugen bedürfen der Anbringung einer gröfseren oder, geringeren Anzahl von Gelenken zwischen den einzelnen Bestandteilen der Kupplung, damit sie die durch die wechselnden Stellungen der Fahrzeuge in Bezug auf einander, namentlich bei Beginn oder am Ende einer Bewegung oder beim Befahren von Krümmungen bedingten Lagenänderungen jederzeit leicht zulassen.
- Die Erfindung betrifft eine Rohrkupplung, welche vollständig gclcnklos ist und dennoch die allseitige Beweglichkeit der gekuppelten Theile gestattet, gleichzeitig aber auch sich selbsttätig abdichtet. ·The previous metal pipe couplings for connecting the steam or air lines of railway vehicles require the attachment of a larger or smaller number of joints between the individual components of the coupling, so that they can handle the changing positions of the vehicles in relation to each other, namely at the beginning or on Easily allow changes in position caused by the end of a movement or when traveling on bends at any time.
The invention relates to a pipe coupling which is completely closed and yet allows all-round mobility of the coupled parts, but at the same time also seals itself automatically. ·

Die Kupplung besteht im .wesentlichen aus ittvei an den zu verbindenden -Leitungsrohren, angebrachten Trichtern und einem in dieselben einschiebbaren Verbindungsröhr,-welch letzteres in den Trichtern allseitig frei beweglich gehalten und durch eine in denselben unter dem Druck des durchgehenden Dampfes bezw. der Luft stehende Membran direct öder unter Ver-. mittclung einer Stopfbüchsenanordnung sclbstthätig abgedichtet wird. . .The coupling consists essentially of ittvei on the line pipes to be connected, attached funnels and a connecting tube which can be pushed into the same, the latter in the funnels held freely movable on all sides and by one in the same under the Pressure of the continuous steam respectively. the membrane standing directly or under pressure. is automatically sealed by means of a stuffing box arrangement. . .

Auf der Zeichnung sind in Fig. 1 bis 3 drei Ausführungsformen dieser Rohrkupplung in je einer Hälfte im Längsschnitt' dargestellt; die zweite, nicht dargestellte Hälfte ist symmetrisch dazu.On the drawing in Figs. 1 to 3 are three Embodiments of this pipe coupling in each half shown in longitudinal section '; the second half, not shown, is symmetrical to.

In Fig. ι ist S einer der beiden Trichter,' der an '. dem einen Leitungsrohr R mittels Flantschverschraubung. befestigt ist. Mit demselben. ist eine beliebig geformte, biegsame Membran M aus Metall, Kautschuk, Leder oder dergl. an ihrem Aufsenrande fest verbunden ; dieselbe besitzt eine kreisförmige · Durchlochung, deren Rand an dem einen kegelförmig ausgedrehten Rohrstück A mit- ' tels des aufgeschraubten Ringes B festgehalten wird.In Fig. Ι S is one of the two funnels, 'the on'. one pipe R by means of a flange screw connection. is attached. With the same. a flexible membrane M of any shape made of metal, rubber, leather or the like is firmly connected at its outer edge; the same has a circular perforation, the edge of which is held on the one conically turned tube piece A by means of the screwed-on ring B.

Das Rohrstück A ist in dem mit dem Trichter 5 verschraubten Deckel D verschiebbar und bildet mit dem auf das Ende des letzteren aufgeschraubten, ebenfalls kegelförmig ausgedrehten Flantschtheil E eine Art Stopfbüchse für das in den Trichter S lose eingesteckte Verbindungsrohr F. A piece of the tube is slidable in the hopper 5 is screwed to the lid D and forms with the latter at the end of the screwed-on, also cone-shaped the twisted Flantschtheil E a kind of stuffing box for the loose in the hopper S inserted connecting tube F.

Da der äufsere Durchmesser dieses letzteren Rohres kleiner ist als der lichte Durchmesser des Rohrstückes A und des Flantschtheiles JE, so kann sich das Verbindungsrohr F sowohl in' der Richtung seiner Achse Λ"-Λ', als auch um dieselbe, pendelnd und rotirend bewegen. Since the outer diameter of this latter pipe is smaller than the inside diameter of the pipe section A and the flange part JE, the connecting pipe F can move in the direction of its axis Λ "-Λ ', as well as around it, pendulously and rotating.

Der zwischen den Theilcn A und E verbleibende Ringraum enthält ein geeignetes Packungsmaterial, z. B. Asbest, welches durch den in den Trichter 5 eingelassenen Dampf (oder Prefsluft) unter Vermittlung der Membran M und des Rohrstückes A dicht an das Verbindungsröhr F angedrückt wird, so dafs dieses ohne Beeinträchtigung seiner Beweglichkeit gegen die beiden Trichter selbsttätig abgedichtet wird. The annular space remaining between parts A and E contains a suitable packing material, e.g. B. Asbestos, which is pressed tightly against the connecting tube F by the steam (or pre-air) introduced into the funnel 5 through the intermediary of the membrane M and the pipe section A , so that this is automatically sealed against the two funnels without impairing its mobility.

Bei der in Fig. 2 gezeigten Ausführungsform ist der Rand der Durchlochung der Membran M direct an dem Verbindungsröhr F befestigt, welch letzteres einen kugeldächcnartig abgedrehten Ansatz K besitzt, der sich an denIn the embodiment shown in Fig. 2, the edge of the perforation of the membrane M is attached directly to the connecting tube F , the latter has a spherical roof-like twisted approach K , which is attached to the

Claims

at K ¹ in the same way twisted cover D applies, so that the tube F can swing around the axis -VA 'due to the flexibility of the membrane M. . '

With this arrangement, a displacement of the connecting pipe F in its longitudinal direction is not possible, but can be easily achieved by attaching an ordinary stuffing box seal above the pipe F on top of the cover D , in which case the stuffing box that enables the displacement and the Ball bearing KK ^{1 that} allows pendulum movement must be arranged separately. The latter can, moreover, be implemented in any other way - and also be completely omitted as soon as the applied steam or air pressure is not very great and the thickness of the membrane is chosen so that it does not deflect excessively.

Fig. 3 shows a further embodiment, in which the connecting pipe F by a pipe piece A, which, as in the first-described case; is attached to the membrane M , and is passed through a second pipe section G, which rests against the turned surface K ^{1 of} the funnel cover D by means of the spherical surface K. The connecting pipe F can therefore move both in the seal of the 'axis A'-A' and in a pendulum manner about the latter. . . ■ ■ ·

The membrane M thus causes, as in Fig. Ι, the compression of the packing in the stuffing box and at the same time allows the pipe section G an oscillating movement, similar to the connecting pipe F in Fig. 2.

If the pipe sections A and G are turned out in a conical shape on the inside and their smallest inner diameter is made larger than the outer diameter of the connecting pipe F, the latter can move against the two pipe sections A and G in the longitudinal direction, and also move in a pendulum manner and also with larger deflections Use these two pieces of pipe to perform pendulum movements against the funnel cover D.
