Description

UbergangsbauteilTransition component
Die Erfindung bezieht sich auf ein Übergangsbauteil zur Verwendung zwischen einem Leitungssystem mit Kleinflanschen und einem Leitungssystem mit Steckverschraubungen.The invention relates to a transition component for use between a line system with small flanges and a line system with push-in fittings.
Es ist bekannt, zur vakuumdichten Verbindung von Vakuumpumpen mit zu- oder weiterführenden Leitungen Flanschbauteile einzusetzen (DE-A-24 16 808) . Am Ort der Mündung des in der Oberfläche des Gehäuses der Vakuumpumpe endenden Kanals ist üblicherweise ein Anschlussstutzen mit einem Flansch vorgesehen. Auch die mit dem Anschlussstutzen zu verbindende Leitung weist einen Flansch auf. Die Herstellung der Verbindung selbst erfolgt dadurch, dass die beiden Flansche auf- einandergesetzt und mit Hilfe eines Spannringes oder anderer Flanschverbindungsbauteile in dieser Stellung fixiert werden. In aller Regel sind bei vakuumdichten Verbindungen dieser Art Dichtringe aus Kunststoff, aus Gummi oder auch Metall vorgesehen. Diese befinden sich zwischen den jeweiligen Dichtflächen. Mit Hilfe von Nuten, Zentrierringen oder dergleichen werden sie in ihrer Soll-Lage gehalten. Die Beschädigungsgefahr der an den hervorragenden Flanschen befindlichen Dichtflächen ist hoch. Dieses gilt auch für den Platzbedarf, der notwendig ist, um die Flanschverbindung herzustellen, da beide Hände notwendig sind, um einen Spannring oder andere Flanschverbindungsbauteile aufzusetzen und zu befestigen.It is known to use flange components for the vacuum-tight connection of vacuum pumps with supply or further lines (DE-A-24 16 808). A connection piece with a flange is usually provided at the location of the mouth of the channel ending in the surface of the housing of the vacuum pump. The line to be connected to the connecting piece also has a flange. The connection itself is established by placing the two flanges on top of one another and fixing them in this position with the aid of a clamping ring or other flange connection components. As a rule, sealing rings made of plastic, rubber or metal are provided for vacuum-tight connections of this type. These are located between the respective sealing surfaces. With the help of grooves, centering rings or the like, they are held in their desired position. The risk of damage to the sealing surfaces on the excellent flanges is high. This also applies to the space required to establish the flange connection, since both hands are necessary to put on and fasten a clamping ring or other flange connection components.
Außerdem sind Leituntgssysteme mit Steckverschraubungen bekannt, die bisher nur in der Drucklufttechnik eingesetzt werden (vgl. z. B. Steckverschraubungen der Firma Camozzi Pneumatik) . Sie bestehen aus einem ersten mit einem Gewinde versehenen Abschnitt und einem zweiten, etwa topfförmigen Abschnitt, der eine dichte, lösbare Verbindung mit dem freien Ende eines Kunststoffrohres oder -Schlauches ermöglicht. Das Rohr wird mit einer Hand in den topfförmigen Abschnitt eingesteckt, bis es einen im Inneren des Bauteiles befindlichen O-Ring passiert und einen mechanischen Anschlag erreicht hat. Bestandteil des topfförmigen Abschnittes ist eine auf den Umfang des Kunststoffrohres einwirkende, hülsenförmige Spannzange, die durch eine axiale Bewegung lösbar ist.In addition, control systems with push-in fittings are known which have so far only been used in compressed air technology (see, for example, push-in fittings from Camozzi Pneumatik). They consist of a first threaded section and a second, approximately cup-shaped section, which enables a tight, detachable connection to the free end of a plastic tube or hose. The tube is inserted into the pot-shaped section with one hand until it passes through an O-ring located inside the component and has reached a mechanical stop. Part of the pot-shaped section is a sleeve-shaped collet acting on the circumference of the plastic tube, which can be released by an axial movement.
Steckverschraubungen dieser Art sind auch gewinkelt, schwenkbar und mit vielen Durchmessern auf dem Markt verfügbar. Wesentlich ist, dass die Anschlussleitungen aus einem flexiblen Material bestehen (z.B. Kunststoffe, wie Polyamid, Polyurethan usw. oder Gummi).Push-in fittings of this type are also angled, pivotable and available on the market with many diameters. It is essential that the connection lines consist of a flexible material (e.g. plastics, such as polyamide, polyurethane, etc. or rubber).
Da Leitungssysteme mit Steckverschraubungen die Nachteile der Leitungssysteme mit Kleinflanschen (Gefahr der Beschädigung der Dichtflächen, hoher Platzbedarf zur Herstellung der Verbindungen) nicht aufweisen, ist es das Ziel der vorliegenden Erfindung, die Vorteile des Leitungssystems mit Steckverschraubungen auch in der Vakuumtechnik nutzen zu können.Since line systems with push-in fittings do not have the disadvantages of line systems with small flanges (risk of damage to the sealing surfaces, high space requirement for making the connections) it is the aim of the present invention to be able to use the advantages of the line system with push-in fittings also in vacuum technology.
Erfindungsgemäß wird dieses Ziel durch ein Übergangsbauteil erreicht, das es ermöglicht, bei mit Kleinflanschen ausgebildeten Leitungssystemen oder Geräten auch Leitungssysteme mit Steckverschraubungen einsetzen zu können. Dieses Übergangsbauteil hat die kennzeichnenden Merkmale der Patentansprüche.According to the invention, this goal is achieved by means of a transition component which makes it possible to use line systems with push-in fittings in line systems or devices designed with small flanges. This transition component has the characteristic features of the claims.
Die vorliegende Erfindung beruht auf der Erkenntnis, dass sich die einfach zu handhabenden Leitungssysteme mit Steckverschraubungen überraschenderweise als vakuumdicht erwiesen haben. Es bedurfte deshalb nur noch des erfindungsgemäßen Übergangsbauteiles, um beide Leitungssystem miteinander kompatibel zu machen.The present invention is based on the knowledge that the easy-to-use line systems with push-in fittings have surprisingly proven to be vacuum-tight. It was therefore only necessary to use the transition component according to the invention in order to make the two line systems compatible with one another.
Weitere Vorteile und Einzelheiten der Erfindung sollen an Hand eines in der Figur dargestellten Ausführungsbeispieles erläutert werden.Further advantages and details of the invention will be explained with reference to an embodiment shown in the figure.
Das in der Figur dargestellte Übergangsbauteil 1 besteht aus einem Vakuumflanschadapter 2 mit einem zylindrischen Abschnitt 3, der sich auf der der Dichtfläche 4 des Flansches 2 entgegengesetzten Seite befindet. Adapter dieser Art wurden bisher z.B. als Schlauchtülle verwendet .The transition component 1 shown in the figure consists of a vacuum flange adapter 2 with a cylindrical section 3, which is located on the side opposite the sealing surface 4 of the flange 2. Adapters of this type have previously been used e.g. used as a hose nozzle.
Beim dargestellten Ausführungsbeispiel ist der zylindrische Abschnitt 3 mit einem Innengewinde 5 ausgerüstet, in das der Gewindeabschnitt 6 einer Steckver- schraubung 9 dicht eingeschraubt ist. Für die Dichtheit sorgt u.a. ein Dichtring 7, der sich zwischen der freien Stirnseite des zylindrischen Abschnittes 3 des Vakuumflanschadapters 2 und der Steckverschraubung 9 befindet. Viele andere vakuumdichten Verbindungen zwischen Flanschadapter und Steckverschraubung (z.B. Schweißen, Löten, andere Gestaltungen der Gewinde) sind denkbar. Besonders einfach ist jedoch die Verwendung des ohnehin an handelsüblichen Steckverschraubungen vorhandenen Gewindes .In the illustrated embodiment, the cylindrical section 3 is equipped with an internal thread 5 into which the threaded section 6 of a plug connection screw 9 is screwed tight. A sealing ring 7, which is located between the free end face of the cylindrical section 3 of the vacuum flange adapter 2 and the push-in fitting 9, ensures the tightness. Many other vacuum-tight connections between the flange adapter and push-in fitting (e.g. welding, soldering, other thread designs) are conceivable. However, the use of the thread that is already present on commercially available push-in fittings is particularly simple.
Der zweite Abschnitt 11 der Steckverschraubung 9 ist in an sich bekannter Weise topfförmig ausgebildet. Er nimmt einen O-Ring 12, eine Spannzange 13 und das freie Ende einer Verbindungsleitung 14 auf. Die Spannzange ist eine O-Ring-seitig geschlitzte Hülse mit einem dem O-Ring 21 zugewandten Wulst 15, dem auf der Innenseite des topfförmigen Abschnittes eine Schräge 16 zugeordnet ist. Die Schräge 16 ist so gestaltet, dass sie das Verspannen der in die Hülse 13 eingeführten Leitung 14 bewirkt, wenn eine Zugkraft darauf ausgeübt wird. Durch axiales Verschieben der Spannzange 13 in Richtung O- Ring 12 löst sich diese Verspannung.The second section 11 of the push-in fitting 9 is cup-shaped in a manner known per se. It receives an O-ring 12, a collet 13 and the free end of a connecting line 14. The collet is a sleeve slotted on the O-ring side with a bead 15 facing the O-ring 21, to which an incline 16 is assigned on the inside of the pot-shaped section. The slope 16 is designed such that it causes the line 14 inserted into the sleeve 13 to be braced when a tensile force is exerted thereon. This tension is released by axially moving the collet 13 in the direction of the O-ring 12.
Durch das beschriebene und dargestellte Übergangsbauteil ist es möglich, mit Flanschen ausgerüstete Systeme oder Geräte an mit Steckverschraubungen 9 ausgerüstete Leitungssysteme anzuschließen. Dadurch werden die an sich bekannten Vorteile der Steckverschraubungssysteme - reduzierte Material- und Montagekosten (keine Schrauben, reduzierter Platzbedarf) auch in der Vakuumtechnik nutzbar. Die beschriebene Steckverschraubung 9 hat sich unter den Voraussetzungen als vakuumdicht erwiesen, dass der flexible Werkstoff der Leitung 23 geeignet ist, Temperaturen bis zu 80° C zu ertragen. Außerdem muss seine Oberflächenrauhigkeit derart gewählt werden können, dass die Leitung 23 zusammen mit einem in der Vakuumtechnik üblicherweise eingesetzten O-Ring 21 eine vakuumdichte Trennung sicherstellen können. Dieses ist bei einer Rauhigkeit von kleiner oder gleich Rz 16, vorzugsweise Rz 10, der Fall. Oberflächen von Rz 4 bis Rz 16 sollten außerdem querriefenfrei sein. The described and illustrated transition component makes it possible to connect systems or devices equipped with flanges to line systems equipped with push-in fittings 9. As a result, the known advantages of push-in fitting systems - reduced material and assembly costs (no screws, reduced space requirements) can also be used in vacuum technology. The push-in fitting 9 described has proven to be vacuum-tight under the conditions that the flexible material of the line 23 is suitable for enduring temperatures up to 80 ° C. In addition, its surface roughness must be able to be selected such that the line 23, together with an O-ring 21 usually used in vacuum technology, can ensure a vacuum-tight separation. This is the case with a roughness of less than or equal to R z 16, preferably R z 10. Surfaces from R z 4 to R z 16 should also be free of cross grooves.
