Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft einen Führungskörper mit selbsttätiger Abdichtung gegen die Rohrwand für Rohrreiniger, die durch ein Druckmittel, z. B. Druckwasser, Druckluft, gespannten Dampf o. dgl., in dem zu reinigenden Rohr vorgetrieben werden. Gegenüber bekannten Vorrichtungen dieser Art besteht die Erfindung darin, daß der Führungskörper auf dem Umfang mit einem nachgiebigen Hohlring versehen ist, dessen Inneres mit dem Raum hinter dem Führungskörper so in Verbindung steht, daß das Druckmittel in das Innere des Hohlringes tritt und dessen Außenflächen abdichtend gegen die Rohrwand drückt.The invention relates to a guide body with an automatic seal against the pipe wall for pipe cleaners, which by a pressure medium, z. B. pressurized water, compressed air, tensioned Steam or the like, are driven in the pipe to be cleaned. Compared to known Devices of this type, the invention is that the guide body on the circumference is provided with a resilient hollow ring, the interior of which with the Space behind the guide body is in communication that the pressure medium in the Inside of the hollow ring occurs and its outer surfaces presses sealingly against the pipe wall.

15. Hierdurch wird erzielt, daß der Führungskörper sich den Schwankungen im Rohrdurchmesser anschmiegen kann. Außerdem gestattet der Hohlring ein bequemes Herausziehen des Führungskörpers.15. This ensures that the guide body can cope with the fluctuations in the pipe diameter can hug. In addition, the hollow ring allows the guide body to be pulled out easily.

Nachgiebige Hohlringe, deren Inneres durch Öffnungen nach der Druckmittelseite hin mit dem unter Druck stehenden Raum in Verbindung steht, sind bei Stopfbuchsenpackungen bereits bekannt.Resilient hollow rings, the interior of which through openings on the pressure medium side with communicating with the pressurized space are in the case of gland packings already known.

Ein Führungskörper gemäß der Erfindung ist auf der Zeichnung in einem Ausführungsbeispiel veranschaulicht. Der scheibenartige Körper α ist mit Löchern I versehen, die das Druckmittel durchtreten lassen und es zwingen, in geschlossenen Strahlen auf die Reinigungsvorrichtung einzuwirken.A guide body according to the invention is illustrated in the drawing in one embodiment. The disk-like body α is provided with holes I which allow the pressure medium to pass through and force it to act on the cleaning device in closed jets.

Auf dem Umfang des scheiben artigen Körpers α ist ein Hohlring b aus nachgiebigem Stoff angebracht. Dieser Ring kann z. B. durch zwei Flanschen des scheibenartigen Körpers α festgehalten werden. Der Flansch auf der Druckseite ist mit Löchern e, die das Druckmittel nach dem Ring b durchtreten lassen, versehen und zweckmäßig an dem Führungskörper lösbar befestigt. Der Ring b hat an seiner inneren Fläche zur Einführung des Druckmittels Öffnungen d. Hierdurch wird der Ring im Betrieb immer straff gespannt. Andererseits kann er sich infolge seiner Nachgiebigkeit Unebenheiten der Rohrwände sowie Schwankungen im Rohrdurchmesser anpassen.On the circumference of the disk-like body α , a hollow ring b is attached made of flexible material. This ring can e.g. B. be held by two flanges of the disk-like body α . The flange on the pressure side is provided with holes e, which allow the pressure medium to pass through to the ring b , and is expediently releasably fastened to the guide body. The ring b has openings d on its inner surface for the introduction of the pressure medium. As a result, the ring is always taut during operation. On the other hand, due to its flexibility, it can adapt to unevenness in the pipe walls and fluctuations in the pipe diameter.

Bei dem dargestellten Ausführungsbeispiel sitzt der scheibenartige Körper a, welcher außen die Hohlringdichtung trägt, auf einer Stange, welche an einem Ende die Kupplung mit der Rohrreinigungsvorrichtung vermittelt und am anderen Ende einen Bügel trägt, an welchem ein Seil befestigt ist, das zum Herauswinden der Vorrichtung dient. Der Führungskörper kann auch unmittelbar mit der Rohrreinigungsvorrichtung verbunden sein.In the illustrated embodiment, the disk-like body a, which carries the hollow ring seal on the outside, sits on a rod, which at one end provides the coupling with the pipe cleaning device and at the other end carries a bracket to which a rope is attached, which is used to wind out the device serves. The guide body can also be connected directly to the pipe cleaning device.
