Schlauchhose
Die Erfindung bezieht sich auf Schläuche, bestehend aus einem aus halogenhaltigen Äthylenpolymeren, beispielsweise Polytetrafluoräthylen hergestellten Innenschlauch und einer äußeren Umhüllung aus einem weicheren elastomeren Werkstoff, die den Innenschlauch haftungsfrei und praktisch ohne Formschluß umschließt.The invention relates to hoses consisting of a halogen-containing ethylene polymer, for example polytetrafluoroethylene made inner tube and an outer sheath Made of a softer elastomeric material, which makes the inner tube non-stick and practically without a form fit encloses.
Schläuche dieser Art werden wegen ihrer Beständigkeit gegen chemische Einflüsse und ihrer besonderen physikalischen Eigenschaften bevorzugt dort verwendet, wo es sich um die Durchleitung aggressiver Medien oder um den Einsatz in korrosiver Umgebung oder in Gebieten mit höheren Temperaturwerten handelt. Als nachteilig wird dabei vielfach die verhältnismäßig hohe Biegesteifigkeit der Schläuche empfunden, die zur Anwendung unerwünscht großer Biegeradien zwingt. Die Unterschreitung eines bestimmten Mindestradius beim Verlegen der Schläuche führt erfahrungsgemäß zum Einknicken mit bleibenden Formänderungen der Schlauchwandungen, die neben der sofortigen Wirkung als Drosselstellen die Ursache für spätere vollständige Brüche mit Aufplatzen des betroffenen Schlauches bilden. Da dieses Verhalten der bekannten Schläuche auf den von außen her nicht beeinflußbaren physikalischen Eigenschäften, in erster Linie auch dem Plastizitätsmodul des verwendeten Werkstoffes beruht, mußte man die hierdurch aufgezwungenen Beschränkungen beim Einbau der Schläuche als unumgänglich hinnehmen und beachten, ohne daß es bisher gelungen wäre, die erwünschte Freizügigkeit durch konstruktiv gestaltende Maßnahmen zu erreichen.Hoses of this type are used because of their resistance to chemical influences and their special physical properties preferably used where the passage is more aggressive Media or use in a corrosive environment or in areas with higher temperature values. As a disadvantage is often the felt relatively high flexural rigidity of the hoses, which is undesirably large for the application Forcing bending radii. Falling below a certain minimum radius when laying the hoses experience has shown that it leads to buckling with permanent changes in shape of the hose walls, which in addition to the immediate effect as throttling points, the cause of later complete fractures with bursting of the affected tube. Since this behavior of the known hoses is based on the Physical properties that cannot be influenced from the outside, primarily also the modulus of plasticity based on the material used, one had to comply with the restrictions imposed by this Accept and observe the installation of the hoses as unavoidable, without having succeeded so far to achieve the desired freedom of movement through constructive measures.
Es wurde nun gefunden, daß sich die Geschmeidigkeit und Biegefähigkeit von Schläuchen der eingangs geschilderten Gattung bedeutend erhöhen läßt, wenn gemäß der Erfindung der Innenschlauch druckfest und biegesteif ausgebildet ist und die das Einknicken bei Schlauchbiegungen behindernde Umhüllung aus einem Polyurethan besteht sowie im Vergleich zum Innenschlauch etwa gleiche bis etwa doppelte Wandstärke aufweist.It has now been found that the suppleness and flexibility of hoses of the initially can be significantly increased if the inner tube is pressure-resistant according to the invention and is designed to be rigid and the sheath which prevents buckling in the case of hose bends consists of a polyurethane and compared to the inner tube about the same to about twice the wall thickness having.
Zur Erklärung des Wirkungsmechanismus der Erfindung kann angenommen werden, daß die in sich geschlossene Ummantelung, die haftungsfrei und praktisch ohne Formschluß den steifen Innenschlauch umschließt, die mit dem Einknicken einhergehende Anmelder:To explain the mechanism of action of the invention, it can be assumed that the in closed sheathing that adheres and practically no form fit to the stiff inner tube encloses the notifying party associated with the buckling:

Durchmesservergrößerung nach beiden Seiten rechtwinklig zur Biegeebene unterdrückt. Sie wirkt gleichsam als Führungsrohr im Sinne einer Verteilung der Knickspannungen auf einen größeren Schlauchabschnitt und verhindert das Auftreten von Knickfalten schon im Entstehen. Diese Wirkung tritt bei den bekannten Schläuchen nicht ein.Enlargement of the diameter on both sides at right angles to the bending plane suppressed. It works as it were as a guide tube in the sense of a distribution of the buckling stresses over a larger hose section and prevents creases from occurring as they arise. This effect occurs the familiar hoses.
Im Vergleich zu diesen zeigen die erfindungsgemäßen Schläuche ein weitaus günstigeres Biegeverhalten, größere Geschmeidigkeit und leichtere Biegefähigkeit und lassen sich in wesentlich kleineren Krümmungsradien ohne Auftreten von Knickstellen abbiegen.Compared to these, the hoses according to the invention show a much more favorable bending behavior, greater suppleness and easier bendability and can be broken down into much smaller ones Bend radii of curvature without occurrence of kinks.
