Description
"Druckbehälter aus Kunststoff II Die Erfindung betrifft einen Druckbehälter aus Kunststoff, vorzugsweise einen nach dem Extrusionsblasverfahren hergestellten Druckbehälter mit Schraubflansch zum Anschließen von Armaturen. "Pressure vessel made of plastic II The invention relates to a pressure vessel made of plastic, preferably one produced by the extrusion blow molding process Pressure vessel with screw flange for connecting fittings.
Druckbehälter aus Kunststoff mit Schraubflansch zum Anschließen von Armaturen sind an sich bekannt.Plastic pressure vessel with screw flange for connecting Fittings are known per se.
Der Erfindung liegt die Aufgabe zugrunde, den Schraubflansch an dem Druckbehälter so anzuordnen, daß der Behälter auch bei hohen Drücken völlig dicht ist.The invention is based on the object of the screw flange on the To arrange pressure vessels so that the vessel is completely tight even at high pressures is.
Das wird erfindungsgemäß dadurch erreicht, daß die Behälteröffnung mit einem zylinderförmigen Halsstück versehen ist , auf welchem der im Querschnitt U-förmige Flansch, vorzugsweise Schraubflansch, zur Anordnung von Armaturen aufgesetzt ist, wobei der U-förmige Flansch das Halsstück übergreift.This is achieved according to the invention in that the container opening is provided with a cylindrical neck piece, on which the in cross section U-shaped flange, preferably screw flange, placed on the arrangement of fittings is, wherein the U-shaped flange engages over the neck piece.
Dabei kann die Armatur mit dem Flansch eine Einheit bilden, oder aber mit dem Flansch selbst wieder verschraubt sein.The valve can form a unit with the flange, or else be screwed back to the flange itself.
Nach einem weiteren Merkmal der Erfindung liegt der innen liegende Teil des Flansches, der einen Ring darstellt, an der inneren Fläche des Halsstückes an.According to a further feature of the invention, the interior is located Part of the flange, which is a ring, on the inner surface of the neck piece at.
Weiterhin übergreift der innen liegende Teil des Flansches das Ende des Halsstückes zum Behälterinneren hin relativ weit.Furthermore, the inner part of the flange engages over the end of the neck piece towards the inside of the container relatively far.
Dadurch ist erreicht, daß infolge des Anliegens und des weit übergreifenden inneren Teiles des Hals stückes der Behälter sehr dicht wird, da die auf den innen liegenden Teil in radialer Richtung wirkenden Kräfte immer größer sind als die in axialer Richtung des Behälters wirkenden Kräfte.This achieves that as a result of the concern and the far-reaching inner part of the neck piece of the container is very tight, because the on the inside forces acting in the radial direction are always greater than those in forces acting in the axial direction of the container.
Der innen liegende Teil des Flansches wird somit durch den Behälterdruck fest an die innere Fläche des Halsstückes angepreßt.The inner part of the flange is thus affected by the pressure in the container firmly pressed against the inner surface of the neck piece.
Dabei kann an der Stirnseite des Hals stückes eine Dichtung angeordnet sein die den Behälter auch von außen her vor irgendwelchen Einflüssen schützt.A seal can be arranged on the end face of the neck piece which protects the container from any external influences.
Nach einem weiteren Merkmal der Erfindung bildet das Ende des äußeren Teiles des Flansches einen Abstand von der Ansatzstelle des Halsstückes.According to a further feature of the invention, the end forms the outer Part of the flange a distance from the attachment point of the neck piece.
Dadurch ist erreicht, daß bei einereventuell notwendig werdenden Verstärkung der Behälterwand durch eine weitere anzubringende Schicht, beispielsweise aus Wickellagen, der sich am Ende ausbildende Wulst der Verstärkung in dem durch den Abstand zwischen dem äußeren Teil des Flansches und der Ansatzstelle des Halsstiickes bildenden Raum Platz findet.This ensures that if a reinforcement becomes necessary the container wall by a further layer to be attached, for example made of wrapped layers, the bead of reinforcement that is formed at the end in the one caused by the distance between the outer part of the flange and the attachment point of the neck piece forming space Takes place.
In der Zeichnung ist eine beispielsweise Ausfiihrungsform dargestellt.An exemplary embodiment is shown in the drawing.
Die Behälterwand des Druckbehälters aus Kunststoff ist mit i bezeichnet. An der Behälteröffnung ist ein zylinderförmies Halsstück 2 angesetzt. Auf diesem zylinderförmigen Hals stück ist der im 4uerschnitt U-förmige Flansch 3 aufgesetzt. Der innen liegende Teil 4 des Flansches übergreift dabei das Ende des Halsstückes relativ weit. Außerdem liegt der innere Teil 4 des Flansches an der Innenfläche 5 des Halsstückes an. Der äußere Teil 6 des Flansches ist als Schraubverbindung ausgebildet und dient zur Befestigung des Flansches an dem Halsstück. Die Gewinde sind mit 7 bezeichnet.The container wall of the pressure vessel made of plastic is denoted by i. A cylindrical neck piece 2 is attached to the container opening. On this one The cylindrical neck piece is placed on the flange 3, which is U-shaped in cross section. The inner part 4 of the flange engages over the end of the neck piece relatively far. In addition, the inner part 4 of the flange lies on the inner surface 5 of the neck piece. The outer part 6 of the flange is a screw connection designed and used to attach the flange to the neck piece. The threads are denoted by 7.
Das Ende 9 des äußeren Teiles des Flansches 3 bildet dabei einen Abstand II von der Ansatzstelle 8 des Halsstückes 2.The end 9 of the outer part of the flange 3 forms a distance II from the attachment point 8 of the neck piece 2.
In den durch den Abstand H gebildeten Raum um das Halsstück kann bei einer eventuell notwendig werdenden Verstärkung der Behälterwandung 1 der sich bildende Wulst Platz finden. Der Wulst trägt das Bezugszeiclien 14.In the space formed by the distance H around the neck piece can be any reinforcement of the container wall 1 that may become necessary is the one that is being formed Find space for bead. The bead bears the reference 14.
Die Ausbildung des Flansches in der gezeigten Weise stellt sicher, daß der Behälter äußerst dicht ist; denn die auf die Fläche 10 wirkenden Kräfte infolge des Druckes des Behälterinhaltes sind jeweils immer größer als die auf die Fläche 11 wirkenden Kräfte des inneren Teiles 4 des Flansches 3. An der Stirnfläche 12 des Hals stückes kann eine Dichtung 13 angeordnet sein, die zusätzlich den Behälterinhalt gegen Einflüsse von außen schützt.The formation of the flange in the manner shown ensures that the container is extremely tight; because the forces acting on the surface 10 due to the pressure of the container contents are always greater than those on the Surface 11 acting forces of the inner part 4 of the flange 3. At the end face 12 of the neck piece, a seal 13 can be arranged, which also includes the container contents protects against external influences.
