Description
Die Erfindung betrifft einen Druckbehälter zur Speicherung von flüssigen oder gasförmigen Medien, umfassend einen Kunststoffkernbehälter mit zumindest einem zylindrischen Kragen, der in dem radialen Zwischenraum zwischen einem darin eingesetzten Metallzylinder und einem den Kragen außenseitig umschließenden Metallkörper mit einem radial nach außen vorstehenden Flansch angeordnet ist, wobei der Metallzylinder zumindest eine radial nach außen offene Nut aufweist, in die eine dichtend an den Kragen angepresste O-Ring - Dichtung eingesetzt ist, wobei eine Metallarmatur mit einem Außengewinde in das von dem Metallzylinder abgewandte Ende des Metallkörpers eingeschraubt ist und wobei der Kunststoffkernbehälter und der Flansch von einer Stützhülle aus einem Faserverbundstoff zumindest anteilig umschlossen sind.The invention relates to a pressure vessel for storing liquid or gaseous media, comprising a plastic core container having at least one cylindrical collar, which is arranged in the radial gap between a metal cylinder inserted therein and a metal body enclosing the collar on the outside with a radially outwardly projecting flange the metal cylinder has at least one radially outwardly open groove into which a sealingly pressed to the collar O-ring seal is inserted, wherein a metal fitting is screwed with an external thread in the remote from the metal cylinder end of the metal body and wherein the plastic core container and the Flange of a support shell of a fiber composite material are at least partially enclosed.

Das Dokument
Der Erfindung liegt die Aufgabe zu Grunde, einen solchen Druckbehälter derart weiter zu entwickeln, dass sich bei geringem Herstellaufwand eine qualitativ bessere und dauerhaftere Dichtigkeit ergibt.The invention is based on the object to further develop such a pressure vessel such that there is a better quality and more durable tightness with low production costs.
Diese Aufgabe wird erfindungsgemäß bei einem Druckbehälter der eingangs genannten Art mit den kennzeichnenden Merkmalen von Anspruch 1 gelöst. Auf vorteilhafte Ausgestaltungen nehmen die Unteransprüche Bezug.This object is achieved with a pressure vessel of the type mentioned above with the characterizing features of claim 1. In advantageous embodiments, the dependent claims relate.
Demgemäß ist es erfindungsgemäß vorgesehen, dass der Metallzylinder einen einstückigen Bestandteil der in den Metallkörper von außen eingeschraubten Metallarmatur bildet, sich unmittelbar an das Außengewinde anschließt und dass der Metallzylinder einen abgestuft kleineren Außendurchmesser hat als die Metallarmatur. Die Metallarmatur kann beispielsweise durch ein Ventil gebildet sein, das unmittelbar in den Druckbehälter eingeschraubt wird. Es ist vorgesehen, dass zumindest eine O-Ring-Dichtung einen mit einem Außengewinde versehenen und in den Metallkörper eingeschraubten Teilbereich des Kragens zwischen dem Metallkörper und dem Metallzylinder verpresst.Accordingly, it is provided according to the invention that the metal cylinder forms an integral part of the metal body screwed into the metal body from the outside, immediately adjoins the external thread and that the metal cylinder has a stepped smaller outer diameter than the metal fitting. The metal fitting may for example be formed by a valve which is screwed directly into the pressure vessel. It is provided that at least one O-ring seal presses a part of the collar, which is provided with an external thread and is screwed into the metal body, between the metal body and the metal cylinder.
Zweckmäßig hat der zumindest eine O-Ring im noch unverspannten, aber in die Nut eingefügten Zustand einen Außendurchmesser, der kleiner ist als der Innendurchmesser des Innengewindes des Metallkörpers, in das die Metallarmatur einschraubbar ist. Hierdurch werden Beschädigungen des mindestens einen O-Rings beim Einfügen und Einschrauben der Metallarmatur in den Metallkörper verhindert.Suitably, the at least one O-ring in the still unstressed, but inserted into the groove state an outer diameter which is smaller than the inner diameter of the internal thread of the metal body into which the metal fitting is screwed. This prevents damage to the at least one O-ring when inserting and screwing the metal fitting into the metal body.
Die erfindungsgemäße Konstruktion ermöglicht ein nachträgliches Einfügen und gegebenenfalls Austauschen der die mindestens eine O-Ring-Dichtung tragenden Metallarmatur in den Metallkörper. Fertigungstechnisch ist dies von großem Vorteil. Es ermöglicht vor allem, die Anzahl der O-Ring-Dichtungen in Abhängigkeit von dem jeweiligen Verwendungszweck zu ändern und O-Ring-Dichtungen auszutauschen oder an einer veränderten Stelle neu zu montieren, wenn Undichtigkeiten festgestellt werden.The construction according to the invention allows a subsequent insertion and optionally replacement of the at least one O-ring seal bearing metal fitting in the metal body. Manufacturing technology, this is a great advantage. In particular, it allows the number of O-ring seals to be changed depending on the application and to replace O-ring seals or remount to a different location if leaks are detected.
Nach einer vorteilhaften Ausgestaltung ist es vorgesehen, dass der Metallzylinder zumindest zwei in Richtung des Innenraums des Druckbehälters aufeinanderfolgende Nuten aufweist, in die jeweils O-Ringe dichtend einsetzbar und mit dem Kragen in Eingriff bringbar sind. Durch mehrere aufeinander folgende Dichtzonen ergibt sich eine Art Labyrintheffekt mit abgestuft verminderter Druckbeanspruchung der einzelnen O-Ring-Dichtungen. Falls eine der O-Ring-Dichtungen unzureichend wirksam ist, beispielsweise durch eine Beschädigung oder Verschleiß, kann die andere O-Ring-Dichtung die Dichtwirkung insgesamt noch erfüllen. Für die Dauerhaftigkeit der Dichtheit ist das von großem Vorteil. Vor allem das natürliche Setzverhalten des gewöhnlich aus einem thermoplastischen Werkstoff bestehenden Kunststoffkernbehälters, im Fachgebiet auch als Liner bezeichnet, mit dem der Druckbehälter ganz ausgekleidet ist, wird hierdurch besser kompensiert. Natürlich kann der Liner auch aus abweichenden Werkstoffen wie z.B. aus Metall bestehen.According to an advantageous embodiment, it is provided that the metal cylinder has at least two in the direction of the interior of the pressure vessel consecutive grooves in the respective O-rings are sealingly insertable and engageable with the collar. By several successive sealing zones results in a kind of labyrinth effect with graduated reduced compressive stress of the individual O-ring seals. If one of the O-ring seals is insufficiently effective, for example due to damage or wear, the other O-ring seal can still fulfill the overall sealing effect. For the durability of the tightness that is of great advantage. Above all, the natural setting behavior of the usually consisting of a thermoplastic material plastic core container, also referred to in the art as a liner with which the pressure vessel is completely lined, is thereby better compensated. Of course, the liner can also consist of dissimilar materials such as metal.
Der mindestens eine O-Ring besteht vorteilhaft aus elastomerem Werkstoff, um Setzerscheinungen eines aus polymerem und insbesondere aus thermoplastischem Werkstoff bestehenden Liners besser kompensieren zu können. O-Ring-Dichtungen aus abweichenden Werkstoffen können gleichwohl ebenfalls verwendet werden, beispielsweise solche aus PTFE. Neben einer guten Chemikalienbeständigkeit zeichnen sich solche O-Ring-Dichtungen auf Grund des dem PTFE eigenen Memory-Effektes durch eine gute Dauerelastizität aus.The at least one O-ring is advantageously made of elastomeric material in order to be able to better compensate for settling phenomena of a liner consisting of polymeric and in particular of thermoplastic material. However, O-ring seals made of dissimilar materials can also be used, for example those made of PTFE. In addition to a good chemical resistance, such O-ring seals are characterized by a good permanent elasticity due to the own memory effect of the PTFE.
Als vorteilhaft hat es sich bewährt, wenn zumindest eine O-Ring-Dichtung einen zylindrischen Teilbereich des Kragens mit einem zylindrischen Innenabschnitt des Metallkörpers verpresst. Der Kragen kann bei einer solchen Bauform den von der O-Ring-Dichtung ausgeübten Kräften nicht in unkontrollierbarer Weise ausweichen. Für ein dauerhaft gutes Abdichtergebnis ist das von großem Vorteil.It has proven to be advantageous if at least one O-ring seal presses a cylindrical portion of the collar with a cylindrical inner portion of the metal body. The collar can not avoid the forces exerted by the O-ring seal forces in an uncontrollable manner in such a design. This is a great advantage for a permanently good sealing result.
Hierdurch wird sichergestellt, dass eine besonders präzise und statisch stabile Festlegung des Kragens in axialer Richtung erreicht wird, was ebenfalls ein gutes Abdichtungsergebnis begünstigt. Die im Bereich von Gewindeverbindungen zunächst immer vorhandenen Freiräume ermöglichen dem thermoplastischen Linerwerkstoff des Kragens die Freiräume durch Fließprozesse auszufüllen unter der Wirkung der adialen Verpressung durch die dauerelastische O-Ring-Dichtung aus einem Elastomerwerkstoff oder aus PTFE. Dies trägt dazu bei, Überlastungen zu verhindern und die Dauerhaftigkeit der Abdichtung zu verbessern.This ensures that a particularly precise and static stable determination of the collar is achieved in the axial direction, which also favors a good sealing result. The free spaces that always exist in the area of threaded connections enable the thermoplastic liner material of the collar to fill in the free spaces through flow processes under the effect of adial compression by the permanently elastic O-ring seal made of an elastomer material or PTFE. This helps to prevent overloads and improve the durability of the seal.
Der Metallzylinder ist zweckmäßig an dem dem Innenraum zugewandten Ende kegelig verjüngt auf einen Innendurchmesser, der höchsten so groß und zweckmäßig kleiner ist als der Innendurchmesser des Kragens. Er kann daher problemlos nachträglich eingefügt werden, ohne dass eine Beschädigung des Kragens befürchtet werden müsste.The metal cylinder is suitably tapered conically at the end facing the interior to an inner diameter which is as large and expediently smaller than the inner diameter of the collar. It can therefore easily be added later without fear of damaging the collar.
Das Außengewinde kann an dem der Zylinderfläche zugewandten Ende in einer durch den Metallzylinder begrenzten Kegelfläche enden. Bei einer Anlageberührung an dem Kragen wird dieser durch die Kegelfläche zusätzlich mit der Innenwandung des Metallkörpers verpresst und insbesondere vermieden, dass sich eine für eine gute Abdichtung nachteilige, unkontrollierte Deformation des Kragens ergibt.The external thread can end at the end facing the cylindrical surface in a conical surface delimited by the metal cylinder. In an investment contact with the collar this is additionally pressed by the conical surface with the inner wall of the metal body and in particular avoided that results in a good for a good seal, uncontrolled deformation of the collar.
Der Kragen kann zur weiteren Verbesserung des diesbezüglichen Effektes an dem vom Innenraum abgewandten Ende in einer hohlkegeligen Fläche enden.The collar can end in a hollow conical surface to further improve the effect on the effect at the end facing away from the interior.
Der Metallkörper kann einen Flansch aufweisen, der den Metallzylinder zumindest an dem dem Innenraum zugewandten Ende und zweckmäßig auf seiner ganzen axialen Länge übergreift. Dadurch wird im Bereich der für das gute Abdichtungsergebnis maßgeblichen O-Ring-Dichtungen eine besonders gute Unnachgiebigkeit des Metallkörpers erhalten.The metal body may have a flange which engages over the metal cylinder at least at the end facing the interior and expediently over its entire axial length. As a result, a particularly good intrinsic resistance of the metal body is obtained in the region of the O-ring seals which are decisive for the good sealing result.
Um eine besonders gute Deformationsbeständigkeit des Druckbehälters zu erhalten, kann der Flansch ein dreieckig nach außen verjüngtes Profil haben. Die Einbettung in die aus faserverstärktem Kunststoff bestehende Armierung des Druckbehälters gelingt hierdurch besonders gut. Dafür ist es vor allem wichtig, dass die Außen- und Innenseiten der einander gegenüberliegenden Flächen unter Vermeidung von Abstufungen gleichmäßig ineinander übergehen.In order to obtain a particularly good deformation resistance of the pressure vessel, the flange may have a triangular outwardly tapered profile. The embedding in the reinforcement made of fiber reinforced plastic of the pressure vessel succeeds thereby particularly well. For this it is especially important that the outer and inner sides of the opposing surfaces smoothly merge into each other while avoiding gradations.
Der Metallkörper kann an dem vom Innenraum des Druckbehälters abgewandten Ende mit einem Ringbund versehen sein, der die Stützhülle unmittelbar anliegend übergreift. Relativverschiebungen, die eine Zerstörung einleiten können, werden dadurch zusätzlich verhindert. Außerdem kann der Stützbund mit einem Sechskant versehen sein, um das Ansetzen eines Schraubenschlüssels zu ermöglichen und die Metallarmatur bei Bedarf vor Ort problemlos herausschrauben und ersetzen zu können.The metal body may be provided at the end facing away from the interior of the pressure vessel end with a collar, which engages over the support shell directly adjacent. Relative displacements, which can initiate destruction, are thereby additionally prevented. In addition, the support collar can be provided with a hexagon to allow the attachment of a wrench and unscrew and replace the metal fitting on site if necessary without problems.

Der gezeigte Druckbehälter dient zur Speicherung von flüssigen oder gasförmigen Medien. Er umfasst einen Kunststoffkernbehälter 1 mit einem zylindrischen Kragen 1.1, der in dem radialen Zwischenraum zwischen einem darin eingesetzten Metallzylinder 2 und einem den Kragen 1.1 außenseitig umschließenden Metallkörper 3 mit einem radial nach außen vorstehenden Flansch 3.1 angeordnet ist, wobei der Metallzylinder zumindest eine radial nach außen offene Nut 4 aufweist, in die eine dichtend an den Kragen 1.1 angepresste O-Ring - Dichtung 5 eingesetzt ist, wobei eine Metallarmatur 2.1 mit einem Außengewinde 2.2 in das von dem Metallzylinder abgewandte Ende des Metallkörpers 3 eingeschraubt ist und wobei der Kunststoffkernbehälter 1 und der Flansch 3.1 von einer Stützhülle 7 aus einem Faserverbundstoff ganz umschlossen sind.The pressure vessel shown serves for the storage of liquid or gaseous media. It comprises a plastic core container 1 with a cylindrical collar 1.1 which is arranged in the radial gap between a
Der Metallzylinder 2 bildet einen einstückigen Bestandteil der Armatur 2.1, schließt sich unmittelbar an das Außengewinde 2.2 an und der Metallzylinder 2 hat einen abgestuft kleineren Außendurchmesser als das Außengewinde 2.2. Zwischen dem Außengewinde 2.2 und dem Metallzylinder 2 ist insbesondere kein radial nach außen vorstehender Bund o.ä. vorhanden. Der Metallzylinder 2 ist von einer nicht gezeigten Bohrung in Längsrichtung durchdrungen, durch die in den Innenraum 6 des Druckbehälters ein druckbeaufschlagtes Medium eingespeist und daraus entnommen werden kann. Der Druckbehälter besteht im einfachsten Fall nur aus fünf Teilen.The
Der Metallzylinder 2 weist in Richtung des Innenraums 6 des Druckbehälters aufeinanderfolgende Nuten 4 auf, in die jeweils O-Ring - Dichtungen 5 in radial nach außen offene Nuten dichtend eingesetzt sind. Sie bewirken in dieser Tandemanordnung auf Grund von Labyrintheffekten eine besonders effektive Abdichtwirkung.The
Die dem abzudichtenden Raum 6 zugewandte zumindest eine, dauerelastische O-Ring Dichtung 5 verpresst einen zylindrischen Teilbereich des thermoplastischen Kragens 1.1 mit einem zylindrischen Innenabschnitt des Metallkörpers 3. Da der Kragen durch die der O-Ring - Dichtung radial gegenüberliegende Abstützung auf einer Zylinderfläche nicht ausweichen kann, resultiert langfristig eine besonders gut kontrollierbare Abdichtwirkung.The
Der vom Innenraum 6 abgewandte, dauerelastische O-Ring 5 verpresst einen mit einem Außengewinde versehenen und in den Metallkörper 3 eingeschraubten Teilbereich des thermoplastischen Kragens zwischen dem Metallkörper 3 und dem Metallzylinder 2. Dies begünstigt die axiale Fixierung des Kragens in Längsrichtung auf dem Metallzylinder, was die Abdichtwirkung erheblich verbessert, so dass auch Belastungen durch Temperaturwechsel und Schwingungen gut aufgefangen werden können.The remote from the
Der Metallzylinder 2 ist an dem dem Innenraum 6 zugewandten Ende kegelig verjüngt auf einen Innendruchmesser, der kleiner ist als der Innendruchmesser des Kragens 1.1, um das Einfügen des Metallzylinders 2 in den Kragen 1.1 zu erleichtern.The
Das Außengewinde 2.2 endet an dem der Zylinderfläche 2 zugewandten Ende in einer durch den Metallzylinder 2 begrenzten Kegelfläche 2.4, was ebenfalls das Einfügen des Metallzylinders 2 in den Kragen erleichtert und bei einer gegenseitigen Berührung unerwünschte Deformationen vermeidet.The external thread 2.2 ends at the end facing the
Dies gelingt vor allem in Verbindung mit dem Merkmal, dass der Kragen 1.1 an dem vom Innenraum abgewandten Ende in einer hohlkegeligen Fläche endet.This succeeds especially in conjunction with the feature that the collar 1.1 ends at the end facing away from the interior in a hollow-conical surface.
Der Metallkörper 3 weist einen Flansch 3.1 auf, der den Metallzylinder 2 an dem dem Innenraum 6 zugewandten Ende etwa zu 50% der axialen Länge übergreift. Der Flansch 3.1 bewirkt eine zusätzliche radiale Aussteifung des Metallkörpers 3 im Bereich der für die Abdichtung wichtigen O-Ring - Dichtungen.The
Der Flansch 3.1 hat ein dreieckig nach außen verjüngtes Profil, um seine nahtlose Einbindung in die aus einem Faserverbundwerkstoff bestehende Stützhülle 7 zu ermöglichen.The flange 3.1 has a triangular outwardly tapered profile to allow its seamless integration into the existing of a fiber
Der Metallkörper 3 ist an dem vom Innenraum 6 des Druckbehälters abgewandten Ende mit einem Ringbund 3.3 versehen, der die Stützhülle 7 unmittelbar anliegend übergreift. Die Stützhülle 7 wird dadurch zusätzlich relativ zu dem Metallkörper 3 fixiert.The
Die mit der Erfindung erzielten Vorteile bestehen vor allem in einer wesentlich vereinfachten Konstruktion: Es sind weniger Metallbauteile als bisher erforderlich, was neben einem reduzierten Fertigungsaufwand zu einem verminderten Montageaufwand führt. Außerdem besteht die Möglichkeit, die Dichtwirkung des bereits mit einer Stützhülle aus einem Faserverbundstoff umkleideten Druckbehälters nachträglich an besondere Erfordernisse des speziellen Anwendungsfalls anpassen zu können und die Dichtwirkung durch einen nachträglichen Austausch von O-Ring - Dichtungen zu verbessern oder wiederherstellen zu können.The advantages achieved by the invention are mainly in a much simplified design: There are fewer metal components than previously required, resulting in addition to a reduced manufacturing cost to a reduced assembly cost. In addition, there is the possibility of being able to subsequently adapt the sealing effect of the already clad with a support shell made of a fiber composite pressure vessel to special requirements of the specific application and to be able to improve or restore the sealing effect by a subsequent replacement of O-ring seals.
