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.Of the Invention is based on the object, such a pressure vessel such continue to develop that at low production costs a qualitative better and more permanent tightness results.
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.These Task is according to the invention in a pressure vessel of the type mentioned above with the characterizing features of Claim 1 solved. In advantageous embodiments, the dependent claims relate.
Demgemäss ist es erfindungsgemäß vorgesehen, dass der Metallzylinder einen einstückigen Bestandteil der Metallarmatur bildet, sich unmittelbar an das Außengewinde anschließt und einen abgestuft kleineren Außendurchmesser als das Außengewinde hat und dass zumindest eine O-Ring-Dichtung einen mit einem Außengewinde des Kragens versehenen und in den Metallkörper eingeschraubten Teilbereich des Kragens zwischen dem Metallkörper und dem Metallzylinder verpresst. Die Metallarmatur kann beispielsweise durch ein Ventil gebildet sein, das unmittelbar in den Druckbehälter eingeschraubt wird.Accordingly, it is provided according to the invention, that the metal cylinder is an integral part of the metal fitting forms, connects directly to the external thread and a graded smaller outer diameter as the external thread has and that at least one O-ring seal one with an external thread the collar provided and screwed into the metal body portion of the collar between the metal body and the metal cylinder pressed. The metal fitting can, for example be formed by a valve which is screwed directly into the pressure vessel.
Dadurch, dass die 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, wird sichergestellt, dass eine besonders präzise und statisch stabile Festlegung des Kragens in axialer Richtung erreicht wird, was ein gutes Abdichtungsergebnis begünstigt. Die im Bereich von Gewindeverbindungen stets vorhandenen Freiräume ermöglichen dem Werkstoff des Kragens dabei ein gewisses Ausweichen bei der radialen Verpressung, was dazu beiträgt, Überlastungen zu verhindern und die Dauerhaftigkeit der Abdichtung zu verbessern.Thereby, that the at least one O-ring seal has an externally threaded and in the metal body screwed portion of the collar between the metal body and Pressing the metal cylinder will ensure that one particular precise and statically stable fixing of the collar in the axial direction is achieved, which favors a good sealing result. The always available in the field of threaded connections free space the material of the collar while a certain evasion in the radial compression, which helps to prevent overloading and to improve the durability of the seal.
Zweckmäßig hat die zumindest eine O-Ring-Dichtung 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 eingeschraubt ist. Hierdurch werden Beschädigungen der mindestens einen O-Ring-Dichtung beim Einfügen und Einschrauben der Metallarmatur in den Metallkörper verhindert.Has purpose the at least one o-ring seal in still unstressed, but in inserted the groove Condition an outside diameter, the is smaller than the inner diameter of the internal thread of the metal body, in that the metal fitting is screwed in. This will damage the at least one O-ring seal when inserting and screwing the metal fitting in the metal body prevented.
Die erfindungsgemäße Konstruktion ermöglicht ein nachträgliches Einfügen und gegebenenfalls Austauschen der 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 for subsequent insertion and optionally Replacing 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.
Grundsätzlich genügt eine einzige O-Ring-Dichtung, um die Aufgabe der Erfindung zu lösen.Basically, one is enough single O-ring seal to achieve the object of the invention.
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-Ring-Dichtungen 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.To an advantageous embodiment, it is provided that the metal cylinder at least two successive in the direction of the interior of the pressure vessel Having grooves, sealingly insertable in the respective O-ring seals and engageable with the collar. Through several successive Following sealing zones results in a kind of labyrinth effect with graduated reduced pressure load of the individual O-ring seals. If one the O-ring seals is insufficiently effective, for example by a damage or wear, Can the other O-ring seal Overall, the sealing effect still meet. For the durability of tightness is that of great Advantage. Especially the natural one Setting behavior of the usually off a thermoplastic material existing plastic core container, im Fachgebiet also referred to as liner, with which the pressure vessel completely is lined, this is compensated better. Of course you can the liner also from different materials such. B. of metal consist.
Die mindestens eine O-Ring-Dichtung 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 seal is advantageously made of elastomeric Material to settling one of polymeric and in particular made of thermoplastic material existing liner better compensate to be able to. O-ring seals from different materials however also be used, for example, such PTFE. In addition to a good chemical resistance, such O-ring seals are characterized by of the PTFE own memory effect by a good permanent elasticity.
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.When Advantageously, it has proven if at least one O-ring seal a cylindrical portion of the collar is crimped with a cylindrical inner portion of the metal body. The collar can in such a design of the O-ring seal exerted forces do not dodge in an uncontrollable manner. For a permanently good sealing result is that of great Advantage.
Der Metallzylinder ist zweckmäßig an dem dem Innenraum zugewandten Ende kegelig verjüngt auf einen Innendurchmesser, der höchsten so groß oder zweckmäßig kleiner ist als der Innendurchmesser des Kragens. Er kann daher problemlos nachträglich eingefügt werden, ohne dass eine Beschädigung des Kragens befürchtet werden müsste.Of the Metal cylinder is appropriate to the Interior facing end tapers conically to an inner diameter, the highest so big or purposefully smaller is considered the inner diameter of the collar. He can therefore easily later added be without damage the collar feared would have to be.
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 be on the cylinder surface end facing in a limited by the metal cylinder conical surface. In a contact with the investment at the collar this is in addition to the inner wall by the conical surface of the metal body squeezed and in particular avoided that one for a good Sealing adverse, uncontrolled deformation of the collar results.
Der Kragen kann zur weiteren Verbesserung des diesbezüglichen Effektes an dem vom Innenraum abgewandten Ende in einer hohlkegeligen Fläche enden.Of the Collar can be used to further improve the related Effect on the side facing away from the interior end in a hollow conical area end up.
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.Of the metal body may have a flange which at least on the metal cylinder the interior facing the end and expedient on its entire axial Length overlaps. This will be in the area of for the good sealing result prevail O-ring seals obtained a particularly good intransigence of the metal body.
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.Around a particularly good deformation resistance of the pressure vessel to obtained, the flange may have a triangular outwardly tapered profile. The embedding in the fiber-reinforced plastic existing reinforcement of the pressure vessel succeeds thereby particularly Good. Therefore It is especially important that the outside and inside of each other opposite surfaces evenly blend 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.Of the metal body can with at the end remote from the interior of the pressure vessel with be provided an annular collar which engages over the support shell directly adjacent. Relative displacements that can initiate destruction become thereby additionally prevented. Furthermore can the support collar be provided with a hexagon to attach a wrench to enable and unscrew the metal fitting on site if necessary and replace it.

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 achieved with the invention consist mainly in one much simplified design: There are fewer metal components as previously required, which in addition to a reduced manufacturing cost leads to a reduced installation effort. It is also possible the sealing effect of already with a support shell of a fiber composite jacketed pressure vessel subsequently adapt special requirements of the specific application to be able to and the sealing effect through a subsequent replacement of O-ring seals to be able to improve or restore.
