Abstract
Description
Die Erfindung betrifft ein aufblasbares Rohrdichtkissen für Rohre unterschiedlichen Durchmessers mit einer im Wesentlichen zylindrischen, flexiblen aber unelastischen Wandung mit einem Wandabschnitt, der im aufgeblasenen Zustand des Rohrdichtkissens zur Anlage an der Rohrinnenwand bestimmt ist und mit einem zylindrischen Kissenkern und wenigstens einem den Kissenkern umgebenden Mantelkissen, wobei zur Anlage an der Rohrinnenwand eine radiale Außenwandung des radial außenliegenden Mantelkissens bestimmt ist.The invention relates to an inflatable Pipe sealing cushion for Pipes of different diameters with an essentially cylindrical, flexible but inelastic wall with a wall section that in the inflated state of the pipe sealing cushion for contact with the Inner tube wall is determined and with a cylindrical pillow core and at least one jacket cushion surrounding the pillow core, with the System on the inner wall of the pipe a radial outer wall of the radially outer Coat pillow is determined.
Es ist bekannt, zur Abdichtung von
Rohrleitungen aufblasbare Rohrdichtkissen der oben erwähnten Art
zu verwenden. Aus der
Aus
Die an beliebiger Stelle einsetzbaren bekannten Rohrdichtkissen lassen sich zuverlässig nur über einen nicht allzu großen Bereich der Durchmesservariation einsetzen und sind für große Rohrdurchmesser nur bedingt geeignet, da für durch große Rohrdurchmesser bedingte große Berstradien besonders haltbares Material für einen vorgegebenen Innendruck verwendet werden muss.Those that can be used anywhere Known pipe sealing cushions can only be reliably used over a not too large area the diameter variation and are only conditional for large pipe diameters suitable as for due to the large pipe diameter conditional large Burst radii particularly durable material for a given internal pressure must be used.
Durch
Eine derartige Anordnung weist das Problem auf, dass sie insbesondere für große Rohrdurchmesser zu einer Instabilität zwischen dem rohrförmigen Mantelkissen und dem Kissenkern neigt.Such an arrangement shows that Problem on that they become one especially for large pipe diameters instability between the tubular jacket cushion and the pillow core tends.
Zur Lösung dieses Problems ist erfindungsgemäß ein aufblasbares Rohrdicht kissen der eingangs erwähnten Art dadurch gekennzeichnet, dass zum relativen axialen Festlegen der Mantelwandung des Mantelkissens im stirnseitigen und/oder radial äußeren Bereich mehrere Gurte vorgesehen sind, die von einer Mantelwandung des Kissenkerns ausgehend mit den beiden axialen Endbereichen des Mantelkissens verbunden sind.According to the invention, an inflatable is to solve this problem Pipe-tight cushion of the type mentioned above, that for the relative axial fixing of the jacket wall of the jacket cushion Several straps in the front and / or radially outer area are provided, starting from a jacket wall of the pillow core connected to the two axial end regions of the jacket cushion are.
Die erfindungsgemäßen Gurte haben die Funktion, das mehr oder weniger aufgeblasene Mantelkissen in seiner Form relativ zum Kissenkern zu stabilisieren, sodass ein axiales Verschieben oder „Abrollen" des Mantelkissens vom Kissenkern verhindert wird. Es sind mehrere Gurte vorgesehen, die von der Mantelwandung des Kissenkerns ausgehend mit den beiden axialen Endbereichen des Mantelkissens verbunden sind, wobei jeder Gurt naturgemäß nur mit einem der beiden axialen Endbereiche verbunden ist.The belts according to the invention have the function the more or less inflated coat pillow in its shape relatively stabilize to the pillow core, so that an axial displacement or "unroll" of the coat pillow is prevented by the pillow core. There are several Straps provided, starting from the jacket wall of the pillow core connected to the two axial end regions of the jacket cushion are, with each belt naturally only with one of the two axial end regions is connected.
Das erfindungsgemäße aufblasbare Rohrdichtkissen besteht somit aus dem zylindrischen Kissenkern und wenigstens einem ringförmig ausgebildeten, den Kissenkern umgebenden Mantelkissen, dessen Innenraum mit dem Innenraum des Kissenkerns über die Austrittsöffnungen in einer kommunizierenden Verbindung steht, sodass Kissenkern und umgebendes Mantelkissen über ein einziges Einfüllventil aufblasbar sind. Durch die erfindungsgemäße Aufteilung des Rohrdurchmessers in verschiedene Kissenzonen wird der wirksame Berstradius verkleinert, sodass mit gleichem Material höhere Drücke oder vorgegebene Drücke mit einem weniger stabilen Material realisierbar sind.The inflatable tubular sealing cushion according to the invention thus consists of the cylindrical pillow core and at least one annular trained coat pillow surrounding the pillow core, its interior with the interior of the pillow core over the outlet openings is in a communicating connection, so that pillow core and surrounding Coat pillow over a single fill valve are inflatable. By dividing the pipe diameter according to the invention the effective burst radius is reduced to different pillow zones, so higher with the same material Press or given pressures can be realized with a less stable material.
In einer bevorzugten Ausführungsform verlaufen die Gurte durch den Innenraum des Mantelkissens. Bevorzugt bilden sie jeweils ein Gurtpaar, dessen Gurte sich an im wesentlichen der gleichen radialen Position befinden und sich von der Mantelwand des Kissenkerns zu den beiden unterschiedlichen axialen Endbereichen des Mantelkissens erstrecken. Dabei können die Gurte sich in axialer Richtung kreuzen, d.h. in axialer Richtung vom Kissenkern ausgehend im wesentlichen einander entgegengerichtete Diagonalen bilden. Vorzugsweise erstrecken sich die Gurte von einer Stirnseite des Kissenkerns aus gesehen in radialer Richtung, d.h. sternförmig vom Kissenkern ausgehend.In a preferred embodiment the straps run through the interior of the coat cushion. Prefers they each form a pair of belts, the straps of which are essentially attached the same radial position and from the jacket wall of the Cushion core to the two different axial end areas of the coat pillow. The straps can be axial Cross direction, i.e. starting from the pillow core in the axial direction essentially form opposite diagonals. Preferably The straps extend from one end of the pillow core seen in the radial direction, i.e. Star-shaped starting from the pillow core.
Für die Funktion des aufblasbaren Rohrdichtkissens ist es erforderlich, dass die radiale Innenwandung des Mantelkissens fest an die Wandung des Kissenkerns angeschlossen ist. Da das Rohrdichtkissen vorzugsweise aus einem gummierten Gewebe besteht, ist der feste Anschlusss bevorzugt durch Vulkanisation hergestellt. Dabei ist es bevorzugt, wenn der Kissenkern und das benachbarte Mantelkissen über eine axiale Länge eine gemeinsame Wandung aufweisen.For the function of the inflatable tubular sealing cushion, it is necessary that the radial inner wall of the jacket cushion firmly against the wall of the pillow core is connected. Since the pipe sealing pad is preferably made of a rubberized fabric, the fixed connection is preferably made by vulcanization. It is preferred if the cushion core and the adjacent jacket cushion have a common wall over an axial length.
Der Kissenkern kann selbst als aufblasbares Kissen ausgebildet sein, wobei in diesem Fall das Aufblasen des Mantelkissens nach dem Aufblasen des Kissenkerns über Verbindungsöffnungen in der gemeinsamen Mantelwand zwischen Kissenkern und Mantelkissen erfolgen kann.The pillow core itself can be used as an inflatable pillow be formed, in which case the inflation of the jacket cushion after inflating the pillow core through connection openings in the common jacket wall between the pillow core and the jacket pillow can be done.
