Description

Feuerfeste Schlauchleitung Die Erfindung bezieht sich auf die Anwendung eines ganz bestimmten Schlauches als Innenschlauch für eine feuerfeste Schlauchleitung.Fireproof Hose Line The invention relates to the application a very specific hose as the inner hose for a fire-proof hose line.

Es ist bereits ein aus Gununi oder gummiähnlichen Stoffen hergestellter Schlauch vorgeschlagen worden, der eine zwischen zwei Schichten aus Metalldrahtgeflecht angeordnete anorganische Faserstoffeinlage enthält und gegebenenfalls Perforierungen in der die Einlagen abdeckenden äußeren Gummischicht aufweist.It is already one made from gununi or rubber-like fabrics Hose has been proposed to be placed between two layers of metal wire mesh contains arranged inorganic fiber insert and optionally perforations in the outer rubber layer covering the inserts.

Dieser Schlauch wird gemäß der Erfindung angewendet als Innenschlauch bei einer an sich bekannten feuerbeständigen Schlauchleitung, bei der ein Mantel aus organischen Fasern den Innenschlauch mit Ab- stand konzentrisch umgibt und an den beiderseitigen Armaturen luftdicht und/oder wärmeleitend angeschlossen ist.This tube is under applied to the invention as an inner tube in a per se known fire-resistant hose line, in which a sheath of the organic fibers was the inner hose with shutoff concentrically surrounds and hermetically to the two-side valves and / or is connected in a thermally conductive.

Bei der bekannten feuerbeständigen Schlauchleitung besteht der Innenschlauch aus einer Polytetrafluoräthylenseele mit einer Umhüllung aus Metalldrahtgeflecht.In the known fire-resistant hose line, there is an inner hose made of a polytetrafluoroethylene core with a sheath made of metal wire mesh.

Ein solcher Innenschlauch ist schon vom Material her sehr steif und hat schon bei verhältnismäßig geringer Wandstärke mehr rohrartigen Charakter. Das hierauf aufgebrachte Drahtgeflecht erhöht die unerwünschte Steifigkeit weiterhin, so daß für diese bekannte Schlauchleitung der Nachteil einer geringen Biegsamkeit besteht.Such an inner tube is already very stiff in terms of its material has a more tubular character even with a relatively small wall thickness. That the wire mesh applied to it further increases the unwanted stiffness, so that for this known hose line the disadvantage of poor flexibility consists.

Durch die Anwendung des eingangs erwähnten, an sich bereits vorgeschlagenen Schlauches als Innenschlauch der feuerbeständigen Schlauchleitung werden diese Nachteile beseitigt.By using what was mentioned at the beginning, which has already been proposed per se Hose as the inner hose of the fire-resistant hose line will have these disadvantages eliminated.

Die Zeichnung gibt einen Querschnitt durch eine Schlauchleitung nach der Erfindung wieder. Der Innenschlauch 1 aus Gummi oder gummiähnlichen Stoffen schließt in seiner Wandung eine Schicht 16 aus anorganischen Faserstoffen, beispielsweise Asbest, und wenigstens eine mit dieser in Berührung stehende Schicht 17, 18 aus Stahlgeflecht oder parallelen bzw. sich kreuzenden Stahldrähten ein, die zum Abstützen der Faserstoffschicht dient. Der Außerunantel 19 des Innenschlauchs ist mit Perforierungen 20 versehen, damit etwaige Gasansammlungen infolge der Erhitzung nach außen treten können. Der Außenmantel 19 des Schlauchs ist von einer Lufthülle 12 umgeben, welche von dem konzentrisch mit Abstand um den Schlauch angeordneten Mantel 11 begrenzt wird.The drawing shows a cross section through a hose line according to the invention. The inner tube 1 made of rubber or rubber-like materials includes in its wall a layer 16 of inorganic fiber materials, for example asbestos, and at least one layer 17, 18 in contact with this made of steel mesh or parallel or crossing steel wires, which are used to support the fiber material layer serves. The outer shell 19 of the inner tube is provided with perforations 20 so that any gas accumulations as a result of the heating can escape to the outside. The outer jacket 19 of the hose is surrounded by an air envelope 12 which is delimited by the jacket 11 arranged concentrically at a distance around the hose.
