Description
Verfahren zur Erzielung eines gas- und wasserdichten Abschlusses der Abzweigdosen kabelähnlicher Leitungen Es ist bekannt, die Hohlräume von Abzweigdosen kabelähnlicher Leitungen mit einer flüssigen Masse auszufüllen und dieses Ausfüllen mittels einer Spritze vorzunehmen, die die Flüssigkeit unter Druck in den Hohlraum hineinspritzt. Das Ausfüllen des gesamten Hohlraumes hat jedoch den Nachteil, daß dadurch die Prüfungs- und Veränderungsmöglichkeit der einzelnen Abzweigstellen erschwert wird und die ganze Installation der kabelähnlichen Leitung mehr der normalen Kabelleitung gleicht.Method for achieving a gas- and watertight seal of the Junction boxes of cable-like lines It is known that the cavities of junction boxes to fill cable-like lines with a liquid mass and fill this out using a syringe to make the liquid under pressure into the cavity injects into it. However, filling the entire cavity has the disadvantage that this makes it more difficult to test and change the individual branch points becomes and the whole installation of the cable-like line more of the normal cable line equals.
Bei dem Verfahren nach der Erfindung soll nun die leichtere Montagemöglichkeit der kabelähnlichen Leitung erhalten bleiben, aber der vollkommene Abschluß des Dosenhohlraumes durch das Zerstäuben eines nicht hammbaren Kunstwachses erreicht werden, wobei jedoch entgegen dem Bekannten die Zerstäubung nur bis zum Verschließen kleiner poröser Stellen usw., nicht aber bis zum Ausfüllen des gesamten Hohlraumes durchgeführt wird. Die Neuheit des Verfahrens besteht auch weiter darin, daß gleichzeitig mit dem Zerstäubungsvorgang ein Druckluftstrom in die Dose eingeführt wird, der beim -naturgemäßen Entweichen durch die noch vorhandenen 'kleinen Öffnungen die einzelnen zerstäubten Teile mitreißt und die öffnungen dadurch sicher verschließt. Wird die Druckluft nun weiter überhitzt, so trocknet diese Heißluft etwaige Feuchtigkeit in dem Dosenhohlraum gleichzeitig aus und schafft vor dem endgültigen Verschließen eine feuchtigkeitsfreie Abzweigstelle. Ebenso hat sich die wechselseitige Anwendung des Zerstäubungsvorganges und der Drucklufteinführung als vorteilhaft erwiesen, weil in diesem Falle der nach dem Zerstäubungsvorgang auftretende Luftdruck die zerstäubte Masse, beispielsweise in den Luftkanal einer nicht längsdichten kabelähnlichen Leitung, weit hineingedrückt und somit die Längsdichtigkeit herstellt.In the method according to the invention, the easier assembly option should now the cable-like line are retained, but the complete closure of the socket cavity can be achieved by atomizing a non-hammerable synthetic wax, but contrary to what is known, the atomization is only more porous until it is closed Places, etc., but not carried out until the entire cavity is filled will. The novelty of the process also consists in the fact that simultaneously with the atomization process, a stream of compressed air is introduced into the can -natural escape through the still existing 'small openings the individual entrains atomized parts and thus securely closes the openings. Will the Compressed air is now further overheated, so this hot air dries any moisture in the can cavity simultaneously and creates prior to final sealing a moisture-free junction. Likewise has the reciprocal application the atomization process and the introduction of compressed air have proven to be advantageous, because in this case the air pressure occurring after the atomization process the atomized mass, for example in the air duct of a cable-like one that is not longitudinally impermeable Line, pushed in far and thus creates the longitudinal tightness.
