Stand der TechnikState of the art

Die Erfindung geht aus von einem Druckbehälter nach der Gattung des Hauptanspruchs. Bei einem derartigen bekannten Druckbehälter liegt das Halteglied an den Berührungsflächen der Gehäusehälften. Diese sind an den Berührungsflächen flanschartig erweitert, wobei am Außendurchmesser der Flansche Aussengewinde ausgebildet sind, während das ringförmige Halteglied ein entsprechendes Innengewinde aufweist. Die Gehäusehälften werden mit ihren flanschartigen Teilen in das Halteglied fest und abdichtend eingeschraubt. Eine derartige Verbindung der Gehäusehälften erfordert einen recht hohen Aufwand an Arbeits- und Montagekosten.The invention is based on a pressure vessel according to the preamble of the main claim. In such a known pressure vessel the holding member lies on the contact surfaces of the housing halves. These are flange-like on the contact surfaces expanded, with external threads being formed on the outer diameter of the flanges, while the annular holding member has a corresponding internal thread. The housing halves are with their flange-like parts in the holding member screwed in tightly and sealingly. Such a connection of the housing halves requires a great deal of effort in labor and assembly costs.

Die erfindungsgemäße Anordnung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß der Druckbehälter sehr einfach gestaltet und zu montieren ist.The arrangement according to the invention with the characterizing features The main claim has the advantage that the pressure vessel is very simple to design and assemble.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen MerkinaLe möglich.The measures listed in the subclaims are advantageous developments and improvements of the main claim specified MerkinaLe possible.

halften berühren sich an ebenen Flächen 12 und 13· In den Berührungsflächen 12, 13 ist eine Ringnut lH, lV ausgebildet, die zur Aufnahme des Randwulstes 15 einer Membran 16 aus elastischem Werkstoff dient. Der Randwulst 15 dient zugleich als Dichtung an den Berührungsflächen 12, 13.halves are in contact on flat surfaces 12 and 13 · An annular groove 1H, 1V is formed in the contact surfaces 12, 13, which is used to accommodate the bead 15 of a membrane 16 made of elastic material. The bead 15 also serves as a seal on the contact surfaces 12, 13.

Die beiden Gehäusehälften 10, 11 aus starrem Werkstoff wie Stahl sind durch einen Spannring 17 zusammengehalten. Dieser verläuft quer zur Teilungsebene des Gehäuses und um den Meridian desselben herum. Die Vorspannung im Spannring muß grosser sein, als die durch den maximalen Innendruck (Prüfdruck) entstehende Trennkraft. Eine Sicherung des Spannrings 17 gegen Abrutschen ist an sich nicht erforderlich, da durch die hohe Vorspannkraft große Reibungskräfte auftreten. Es ist jedoch zweckmäßig, ihn gegenüber dem Gehäuse durch einzelne Schweißstellen 18 zu fixieren.The two housing halves 10, 11 made of a rigid material such as steel are held together by a clamping ring 17. This runs transversely to the dividing plane of the housing and around the meridian of the same. The preload in the clamping ring must be greater than the separating force resulting from the maximum internal pressure (test pressure). A backup of the clamping ring 17 against Slipping is not necessary, as the high preload force creates great frictional forces. However, it is It is expedient to fix it with respect to the housing by means of individual welds 18.

Angrenzend an den Spannring ist an einer Gehäusehälfte ein Flüssigkeitsstutzen 19 angeschweißt, in dem eine Bohrung 20 ausgebildet ist, die in den Flüssigkeitsraum 21 des Innenraums mündet. Der Stutzen 19 ist an eine mit Flüssigkeit betriebene Druckmittelanlage angeschlossen.A housing half is adjacent to the clamping ring Liquid nozzle 19 is welded, in which a bore 20 is formed, which into the liquid space 21 of the interior flows out. The connector 19 is connected to a fluid-operated pressure medium system.

Der vom Flüssigkeitsraum durch die iMembran 16 getrennte Gasraum 22 wird über eine die Behälterwand durchdringende Bohrung 23 mit einem Gas unter Druck aufgeladen. Die Bohrung 23 wird anschließend durch eine Kugel 21J und eine Schweißstelle 25 dicht verschlossen. Der Druckbehälter ist damit betriebsbereit .The gas space 22 separated from the liquid space by the membrane 16 is charged with a gas under pressure via a bore 23 penetrating the container wall. The bore 23 is then tightly closed by a ball 2 1 J and a weld 25. The pressure vessel is now ready for use.

Die beiden gleichen Gehäusehälften 10 und 11 sind z. B. durch Tiefziehen einfach herstellbar. Für das Einspannen der Membran 16 sind keine zusätzlichen Befestigungselemente notwendig.The two same housing halves 10 and 11 are z. B. easy to manufacture by deep drawing. For clamping the membrane 16 no additional fastening elements are necessary.

Beim Montieren werden die Gehäusehälften 10 und 11 durch den Randwulst 15 der Membran zentriert. Da der Spannring nicht unbedingt festgeschweißt zu werden braucht, is;■ kein Arbeitsgang Schweißen erforderlich, was oft recht problematisch wegen der Wärmeeinwirkung auf die aus elastischem Werkstoff bestehende Membran 16 ist. Die beiden Gehäusehälften 10 und 11 brauchen selbstverständlich nicht Halbkugelgestalt zu besitzen. Sie können auch teilweise zylindrisch sein und dann in kugelförmige Böden übergehen, Behälterformen, die ebenfalls häufig Verwendung finden. Der Spannring kann auch geringfügig versetzt zur Trennebene verlaufen.During assembly, the housing halves 10 and 11 are centered by the bead 15 of the membrane. Because the tension ring is not absolutely needs to be welded, is; ■ not an operation Welding required, which is often quite problematic because of the effect of heat on the elastic material Membrane 16 is. Of course, the two housing halves 10 and 11 do not need to have a hemispherical shape. They can also be partially cylindrical and then merge into spherical bottoms, container shapes that too often used. The clamping ring can also run slightly offset from the parting plane.
