Abstract

The seal and expansion compensator consists of one or more extensible and/or deformable hollow pieces. Each hollow piece has one or more hollow cavities filled with gases and/or liquids possessing to a greater or lesser degree a sealing capacity. ADVANTAGE - Tension free incorporation of fitments and meters in pipes is made easier and less time needed.

Description

Die Dichtung und der dichtende Dehnungsausgleicher besteht aus einem oder mehreren dehnbaren und/oder verformbaren Hohl­ körpern. Der Hohlkörper hat einen oder mehrere Hohlräume gefüllt mit mehr und/oder weniger verdichtbaren Medien.The seal and the sealing expansion compensator exist from one or more stretchable and / or deformable hollow bodies. The hollow body has filled one or more cavities with more and / or less compressible media.

Grundsätzlich bestehen Abdichtungsmöglichkeiten gegen Gase, Flüs­ sigkeiten und Feststoffe.Basically there are sealing options against gases, rivers liquids and solids.

Als Füllmedien für die Hohlräume dienen Gase und/oder Flüssig­ keiten.Gases and / or liquids serve as filling media for the cavities keiten.

Je nach Aufgabenstellung kann konstruktiv die dichtende oder die dehnende, verformbare Eigenschaft genutzt werden.Depending on the task, the sealing or the stretching, deformable property can be used.

Die Dichtwirkung steigt mit dem Druck des Füllmediums.The sealing effect increases with the pressure of the filling medium.

Die Druckerhöhung kann in zweifacher Weise erfolgen:The pressure can be increased in two ways:

  • a) Kraftwirkung von innen durch Druckerhöhung des Füllmediums infolge Füllmengenerhöhung.a) Effect of force from the inside by increasing the pressure of the filling medium as a result of an increase in the filling quantity.
  • b) Krafteinwirkung von außen auf die Dichtung durch Gegeneinander­ verschiebung der Dichtflächen, d.h. Volumenverkleinerung des Füllmediums.b) External forces acting on the seal against each other displacement of the sealing surfaces, i.e. Volume reduction of the Filling medium.

Die Füllmöglichkeit kann konstruktiv verschiedenartig gestaltet werden. Sie ist nicht Gegenstand der Anmeldung.The filling option can be designed differently will. It is not the subject of the registration.

Als Werkstoff bietet sich für die Basis das Bekannte an. Der Anmeldegegenstand bietet gegenüber dem Bekannten z.B. fol­ gende Vorteile:The known material lends itself to the base. The object of registration offers the acquaintance e.g. fol advantages:

  • a) Bessere Kombinierbarkeit für Dichtungs- und Dehnungsaufgaben.a) Better combinability for sealing and expansion tasks.
  • b) Abdichtung durch einfache Füllmengenerhöhung gegenüber dem Verschieben der Dichtflächen gegeneinander, z.B. durch Schrauben bei Flanschverbindungen.b) Sealing by simply increasing the filling quantity compared to the Shifting the sealing surfaces against each other, e.g. by screws for flange connections.
  • c) Spannungsfreier Einbau von z.B. Armaturen und Meßgeräten in Rohrleitungen, da auch große Maßungenauigkeiten ausgeglichen werden können.c) Stress-free installation of e.g. Fittings and measuring devices in Pipelines, as large dimensional inaccuracies are evened out can be.
  • d) Geringerer Zeitaufwand besonders bei De- und Montage, d.h. auch Erhöhung der Verfügbarkeit.d) Less time required, especially for disassembly and assembly, i.e. also Increase availability.
  • e) Sicherheitstechnische Überwachung direkt durch Überwachung des Füllraumdruckes.e) Safety monitoring directly by monitoring the Filling space pressure.
