Description
Lösbare Flanschverbindung mit druckabhängigem Dichtelement und elastischem Klemmverschluß auf Endlosband Detachable flange connection with pressure-dependent sealing element and elastic clamp closure on endless band
Herkömmliche Flanschverbindungen verwenden als Dichtelemente Flach- oder Ringdichtungen (z.B. O - Ringe), bei denen der notwendige Anpreßdruck meistens mittels Verschraubungen realisiert wird. Durch vorgegebene Anziehmomente (nur mit Hilfsmittel, wie z.B. Drehmomentschlüssel zu bewerkstelligen) und Anzahl der Schrauben wird unabhängig vom Systemdruck eine maximale Verformung der Dichtung erreicht. Je nach Beschaffenheit des Dichtungsmaterials wird eine dauerhafte Verformung hervorgerufen. Deshalb muß in manchen Fällen nach Lösen der Flanschverbindung auch die Dichtung erneuert werden. Darüber hinaus hat diese Lösung den Nachteil, daß die Kraft oft ungleichmäßig auf der auf Dichtung und somit auf den Dichtflächen verteilt wird. Außerdem ist bei manchen Dichtungen notwendig, nach einer gewissen Zeit, die Schrauben nachzuziehen, um die Dichtigkeit zu gewährleisten.Conventional flange connections use flat or ring seals (e.g. O-rings) as sealing elements, where the necessary contact pressure is usually achieved by means of screw connections. By using specified tightening torques (which can only be achieved with tools such as a torque wrench) and the number of screws, a maximum deformation of the seal is achieved regardless of the system pressure. Depending on the nature of the sealing material, permanent deformation is caused. Therefore, in some cases the seal must also be replaced after the flange connection has been loosened. In addition, this solution has the disadvantage that the force is often unevenly distributed across the seal and thus across the sealing surfaces. In addition, with some seals it is necessary to retighten the screws after a certain period of time in order to ensure that they are leak-proof.
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine einfach zu montierende lösbare Flanschverbindung zu schaffen, bei der der äußere Anpreßdruck auf das Dichtelement einen Minimalwert aufweist, der nur notwendig ist, um es der Dichtung zu ermöglichen sich druckabhängig zu verformen und dann zusätzlich abzudichten. Praktisch wird die Energie im System für die Verformung der Dichtung genutzt. Dadurch paßt sich das Dichtelement an die systembedingten Voraussetzungen an und wird nur druckbedingt, also nicht maximal beansprucht.
Wie folgt:The invention specified in claim 1 is based on the problem of creating a detachable flange connection that is easy to assemble and in which the external contact pressure on the sealing element has a minimum value that is only necessary to enable the seal to deform depending on the pressure and then to provide additional sealing. In practice, the energy in the system is used to deform the seal. This means that the sealing element adapts to the system-related requirements and is only subjected to pressure, i.e. not to maximum stress.
As follows:
1. Niederdruck:1. Low pressure:
Doppelseitige radiale Vorspannung beim Einlegen der Dichtung mit Labyrinthwirkung. Siehe (Skizze 1.1)Double-sided radial preload when inserting the seal with labyrinth effect. See (sketch 1.1)
2. Mitteldruck:2. Medium pressure:
Verstärkung der radialen Kräfte und zusätzliche Axialkräfte beim Eindrücken der Klemmen. Siehe (Skizze 1.2)Increased radial forces and additional axial forces when pressing in the clamps. See (sketch 1.2)
3. Hochdruck:3. High pressure:
Zusätzliche druckabhängige Membranwirkung durch Über/Unterdruck im System. Siehe (Skizze 1.3)Additional pressure-dependent membrane effect due to over/underpressure in the system. See (sketch 1.3)
Die Flanschverbindung soll ohne besonderen Hilfsmittel und Fachkenntnisse die Montage/Demontage und eine sichere Funktion ermöglichen. Diese Voraussetzung wird durch die im Schutzanspruch 2 aufgeführten Merkmale des elastischen Klemmverschlusses wie folgt erfüllt:The flange connection should enable assembly/disassembly and safe operation without special tools or specialist knowledge. This requirement is met by the features of the elastic clamp closure listed in claim 2 as follows:
• Der Anpreßdruck wird durch die elastische Verformung des Klemmenverschlusses vorgegeben, dadurch werden keine Hilfsmittel benötigt.• The contact pressure is determined by the elastic deformation of the clamp closure, so no additional tools are required.
• Durch den konstanten Abstand zwischen den Klemmen wird eine gleichmäßige Verteilung der Kraft auf das Dichtelement gewährleistet.• The constant distance between the clamps ensures an even distribution of the force on the sealing element.
• Einfache Montage/Demontage durch Einrasten der Klemmen ohne großen Kraftaufwand, da der Anpreßdruck gering ist.• Easy assembly/disassembly by snapping the clamps into place without much effort as the contact pressure is low.
• Gegenüber den herkömmlichen Flanschverbindungen kann bis zu 80% Montagezeit eingespart werden.• Compared to conventional flange connections, up to 80% assembly time can be saved.
• Vereinfachte Lagerhaltung, da unabhängig von Nennweiten das Flanschprofil, die Klemmen und das Dichtungsprofil die gleichen Maße aufweisen.• Simplified storage, as the flange profile, clamps and sealing profile have the same dimensions regardless of nominal diameters.
Vereinfachte Montage bei runden Flanschen durch Lochstich unabhängige Einbaulage, dadurch wird eine beliebige gegenseitige Verdrehung der Verbindung ermöglicht.
Besonders vorteilhaft im Kunststoff- Apparatebau, da alle Teile, einschließlich Klemmen (bzw. Verschraubungen), aus mediumbeständigen Materialien (Kunststoffe) hergestellt werden können.Simplified assembly of round flanges through hole punch independent installation position, thus allowing any mutual rotation of the connection.
Particularly advantageous in plastic apparatus construction, since all parts, including clamps (or screw connections), can be made of medium-resistant materials (plastics).
Einfache Montagemöglichkeit an unzugänglichen Stellen, da zum schließen des
Klemmenverschlusses sehr wenig Platz gebraucht wird, siehe (Skizze 2.) z.B Verlegung direkt im Schacht
Geeignet für Normung.Easy installation in inaccessible places, as the
Very little space is needed for the terminal closure, see (sketch 2.) e.g. laying directly in the shaft
Suitable for standardization.
