Description
Lösbare Befestigung für quellende Schläuche Schläuche aus Butadien und aus sonstigen in organischen Lösungsmitteln quellbaren Kunststoffen werden für die verschiedensten Zwecke in großem Umfang benutzt, beispielsweise als Zwischenstücke in Treibstoffleitungen. Hierbei besteht die Gefahr, daß der beim Durchfluß von Treibstoffen aufquellende Butadienschlauch von dem Metallrohr abrutscht.Detachable fastening for swelling hoses Hoses made of butadiene and from other plastics that swell in organic solvents are used for used on a large scale for a wide variety of purposes, for example as spacers in fuel lines. There is a risk that the fuel will flow through swelling butadiene hose slips off the metal tube.
Dies wird erfindungsgemäß durch eine neuartige Befestigung verhindert, die sehr einfach anbringbar und trotzdem durchaus zuverlässig ist. Die Befestigung erfolgt erfindungsgemäß mit Hilfe eines über den betreffenden Schlauch geschobenen Schrumpfstückes aus einem Kunststoff, vorzugsweise aus einem Polyvinylderivat, insbesondere aus Polyvinylalkohol. Vor dem Aufschieben wird der Schrumpfring längere Zeit, beispielsweise 12 Stunden lang, in Wasser gelegt. Hierdurch erfolgt eine so starke Quellung, daß der Ring ohne Schwierigkeit über das zu befestigende Ende des Butadienschlauches geschoben werden kann. Beim Trocknen schrumpft der Ring so stark, daß der Buta-dienschlauch trotz seiner Quellung in organischen Lösungsmitteln, z. B. Treibstoffen, fest auf die Unterlage, beispielsweise auf das Metallrohr, aufgepreßt bleibt, so daß eine vollkommen dichte Abschließung gewährleistet ist. Im Gegensatz zu allen bisher verwendeten metallischen Befestigungsarten durch Schlauchschellen oder Spannbänder hat die vorgeschlagene Befestigungsart den Vorteil, daß sie, ohne B.unamaterial bei Quellung durch organische Lösungsmittel zu beschädigen, eine vollkommene Abdichtung ergibt.According to the invention, this is prevented by a new type of fastening, which is very easy to attach and yet absolutely reliable. The attachment takes place according to the invention with the help of a pushed over the hose in question Shrink piece made of a plastic, preferably made of a polyvinyl derivative, in particular made of polyvinyl alcohol. Before being pushed on, the shrink ring is a long time, for example For 12 hours, put in water. This causes such a strong swelling that the ring without difficulty over the end of the butadiene tube to be attached can be pushed. When drying, the ring shrinks so much that the butadiene tube despite its swelling in organic solvents, e.g. B. fuels, firmly the pad, for example on the metal tube, remains pressed, so that a completely tight seal is guaranteed. In contrast to all previously used metallic fastening types by hose clamps or straps has the proposed Type of fastening has the advantage that they swell without B. unamaterial Damage from organic solvents will result in a perfect seal.
Bei großen Schlauchlängen können derartige Schrumpfringe mit Vorteil auch in passender Verteilung verwendet werden, um ein zu starkes Aufblähen des Schlauches zu verhindern.Such shrink rings can be of advantage for long hose lengths can also be used in a suitable distribution to avoid excessive inflation of the hose to prevent.
Die Erfindung würde vorstehend in erster Linie am Beispiel eines Butadienschlauches unter Benutzung eines Schrumpfringes aus Polyvinalalkohöl beschrieben. Die Erfindung ist nicht an diese beiden Materialien gebunden. Sowohl für den Schlauch wie für den Schrumpfring können auch andere Materialien verwendet werden, wobei dafür Sorge getragen werden muß, für den Schrumpfring jeweils ein Material auszuwählen, welches durch die in Frage stehenden Flüssigkeiten oder sonstigen Stoffe, die ein Quellen des betreffenden zu befestigenden Schlauches verursachen, nicht aufgequellt wird. Vorzugsweise wählt man den Werkstoff für den Schrumpfring ferner unter dem Gesichtspunkt aus, daß dieses Material seinerseits durch Mittel zum Quellen gebracht werden kann, die auf den Werkstoff des Schlauches nicht quellend wirken.The invention would be above primarily using the example of a butadiene tube described using a shrink ring made of polyvinyl alcohol. The invention is not bound by these two materials. Both for the hose and for Other materials can be used with the shrink ring, taking care must be worn to select a material for the shrink ring, which by the liquids in question or other substances that swell cause of the hose to be fastened in question, does not swell. The material for the shrink ring is preferably also selected from the point of view from the fact that this material in turn can be made to swell by means, which do not have a swelling effect on the material of the hose.
Die Befestigungsvorrichtung eignet sich nicht nur für Schläuche, die auf Metallrohre aufgezogen werden, sondern auch für andere Anschlußstellen von Schläuchen u. dgl.The fastening device is not only suitable for hoses that be drawn on metal pipes, but also for other connection points of hoses and the like
