Abstract
Description
Die Erfindung betrifft Hülsrohre für Einbaugarnituren. Die Erfindung trifft sowohl auf starre Einbaugarnituren mit nur ein Hülsrohr zu aber auch auf teleskopierbare Einbaugarnituren, bei denen mindestens ein oberes Hülsrohr und ein unteres Hülsrohr vorhanden ist. Die Hülsrohre sollen dabei das darin befindliche Gestänge vor mechanischer Beschädigung und Korrosion durch das umliegende Erdreich schützen. Einbaugarnituren dienen dabei zur Betätigung von Armaturen an unzugänglichen Stellen, wie zum Beispiel solcher Armaturen zum Absperren von Gasleitungen oder Wasserleitungen im Erdreich.The The invention relates to sleeve tubes for installation kits. The invention applies both to rigid built-in sets with only a sleeve tube but also on telescopic installation kits, where at least an upper sleeve tube and a lower sleeve tube available is. The tube tubes should thereby be located in the linkage before mechanical damage and Protect corrosion from the surrounding soil. Serving installation trims while to the operation from fittings to inaccessible Places, such as such fittings for shutting off gas lines or water pipes in the ground.
Die Hülsrohre der Einbaugarnituren sollen insbesondere das innenliegende Gestänge auch vor eindringendem Erdreich und Wasser sowie im Winter vor Eis schützen, damit stets die sichere Betätigung der darunter im Erdreich liegenden Armaturen gewährleistet ist.The sleeve pipes the built-in trimmings should in particular the internal linkage also protect against the ingress of soil and water and in winter against ice, so always the safe operation of underneath lying in the ground is ensured fittings.
Es ist also bisher so, dass die Hülsrohre meistens aus einem korrosionsbeständigem thermoplastischem Werkstoff hergestellt sind, der auch bei Frost nicht versprödet und bricht. Dieser Werkstoff ist jedoch auch gleichzeitig relativ weich. Da das Erdreich um die Einbaugarnitur bei ihrem Einbau verdichtet wird kann nicht ausgeschlossen werden, das insbesondere Steine aber auch Eis im Winter sich in die Hülsrohre drücken. Dadurch können Beulen oder Risse entstehen. Eindringendes Erdreich, Wasser und Eisbildung können die Funktion der Einbaugarnitur beeinträchtigen. Wenn möglicherweise die Einbaugarnitur oder die darunter im Erdreich liegende Armatur nach langer Zeit repariert werden muß, kann insbesondere bei teleskopierbaren Einbaugarnituren keine Teleskopierung mehr erfolgen, weil die Teleskopabdichtung wegen der Beulen nicht mehr funktioniert oder die Rohre ineinander klemmen.It so far so is that the tube tubes mostly made of a corrosion resistant thermoplastic material are made, even in frost not embrittled and breaks. However, this material is also relative at the same time soft. As the soil compacts around the installation set during their installation can not be excluded, but in particular stones also ice in the winter in the tubes to press. Thereby can Bumps or cracks occur. Penetrating soil, water and Ice formation can impair the function of the installation kit. If possible the installation set or the below lying in the ground fitting After a long time must be repaired, especially in telescopic Installation kits no longer telescoping, because the telescopic seal because of the bumps stops working or the tubes into each other terminals.
Aufgabe der Erfindung ist es, Hülsrohre für Einbaugarnituren zu schaffen, die trotz harter Einlagerungen wie Steinen und Eisdruck im verdichtetem Erdreich das Entstehen von Beulen oder Rohrbeschädigungen verhindern. Dabei sollen die Hülsrohre auch bei Frost mechanisch beständig bleiben. Bei einer eventuellen Reparatur der Einbaugarnitur oder der Armatur nach langer Zeit soll die Einbaugarnitur sicher auch nach einer notwendigen Teleskopierung wasserdicht bleiben.task The invention is sleeve tubes for installation kits despite hard deposits such as stones and ice pressure in compacted soil the formation of dents or pipe damage prevent. The tube tubes should also mechanically resistant to frost stay. In case of repair of the installation kit or the Fitting after a long time, the installation set is sure to after remain watertight for a necessary telescoping.
Erfindungsgemäß wird die Aufgabe zur Schaffung von Hülsrohren für Einbaugarnituren mit einem nicht teleskopierbarem Hülsrohr und auch für teleskopierbare Einbaugarnituren mit mindestens einem oberem Hülsrohr und einem unterem Hülsrohr dadurch erreicht, dass die Hülsrohre der Einbaugarnituren zweischalig ausgebildet sind, wobei die äußere Hülsrohrschale aus einem festem und korrosionsfestem Material und die innere Hülsrohrschale aus weicherem und korrosionsfestem Material besteht.According to the invention Task to create sleeve pipes for installation kits with a non-telescopic sleeve tube and also for telescopic Built-in trims with at least one upper sleeve tube and a lower sleeve tube achieved that the tube tubes the built-in sets are formed with two shells, wherein the outer sleeve tube shell made of a solid and corrosion-resistant material and the inner tube shell Made of softer and corrosion-resistant material.
Eine
zweckmäßige Ausführung der
Erfindung kann darin bestehen dass die äußere Hülsrohrschale und die innere
Hülsrohrschale
jeweils ineinandergesteckte Einzelrohre sind.
Eine andere zweckmäßige Ausführung der
Erfindung kann auch darin bestehen dass die äußere Hülsrohrschale und die innere
Hülsrohrschale
durch Schweißen,
Kleben oder Pressen miteinander verbundene Einzelrohre sind.An expedient embodiment of the invention may consist in that the outer sleeve tube shell and the inner tube shell each are nested in individual tubes.
Another expedient embodiment of the invention may also consist in that the outer sleeve tube shell and the inner sleeve tube shell are interconnected by welding, gluing or pressing single tubes.
Die zweischaligen Hülsrohre der Einbaugarnituren können auch als Verbundwerkstoff ausgebildet sein, wobei die äußere Hülsrohrschale mit den festem und korrosionsfestem Materialeigenschaften in die innere Hülsrohrschale aus weicherem und korrosionsfestem Material übergeht.The clam shell tubes the installation kits can be formed as a composite material, wherein the outer sleeve tube shell with the solid and corrosion resistant material properties in the inner tube shell made of softer and corrosion-resistant material.
Es kann zweckmäßig sein durch faserige oder körnige Einlagerungen metallischer, anorganischer oder organischer Art in den Grundwerkstoff der äußeren Hülsrohrschale die festem und korrosionsfestem Materialeigenschaften zu erreichen.It may be appropriate by fibrous or granular Inlay of metallic, inorganic or organic kind in the base material of the outer tube shell to achieve the solid and corrosion-resistant material properties.
In einer vereinfachten Ausführung kann es sich auch um ein Hülsrohr handeln, bei denen die Eigenschaften der äußere Hülsrohrschale mit den fester und korrosionsfestem Materialeigenschaften und der inneren Hülsrohrschale mit den weicherem und korrosionsfestem Materialeigenschaften derart vereint sind, das in einen weicherem und korrosionsfestem Material faserige oder körnige Einlagerungen metallischer, anorganischer oder organischer Art gleichmäßig eingelagert sind.In a simplified version it can also be a sleeve tube act in which the properties of the outer tube shell with the firmer and corrosion-resistant material properties and the inner tube shell with the softer and corrosion resistant material properties such united in a softer and more corrosion resistant material fibrous or grainy Storage of metallic, inorganic or organic species stored evenly are.
Ein Ausführungsbeispiel der Hülsrohre für Einbaugarnituren wird in den nachfolgenden Zeichnungen erläutert.One embodiment the tube tubes for installation kits is explained in the following drawings.
