Description
Gegenstands Hydro--pneumatischer Druckspeicher mit zwei Membranen' Kugelähnliche Druckspeicher, die aus zwei Kugelhälften zusammengesetzt werden, haben den Nachteil, da!.) die Verbindung der beiden Hälften am Größtkreis-der Kugel ist und deshalb die Verbindungsstelle der größten Beanspruchung ausgesetzt ist. -Durch vorliegende Erfindung ist dieser Nachteil behoben. Es wird von der Tatsache ausgegangen, daß sich der Durchmesser des Druckspeichers verringert, wenn man ihn mit einer zylindrischen Partie versieht, ohne dabei den Gesamtinhalt zu verändern. Der Größtdurchmessec wird-dadurch-kleiner als der eines kugeligen Druckspeichers gleicher. Inhalts. Solche Druckspeicher haben jedoch den, Nachteil, daß sie unter innerem Überdruck eine kugelige Form annehmen wollen: Die Schweißverbindung hat also außer der Zugbeanspruchung zusätzlich noch eine Biegebeanspruchung aufzunehmen. Sofern die beiden Hälften des Druckspeichers durch eine Schweißnaht verbunden werden, ist noch zu berücksichtigen, daß die Membrane, die im zylindrischen Teil des Druckspeichers eingeklemmt ist, durch die Hitze der Schweissung gefährdet ist, Zur Beseitigung dieser Mängel wird vorgeschlagen, die Druckspeicher mit zylindrischem Teil aus Kugelhälften mit zylindrischem-Ansatz herzustellen und mit einem Innenring zu versehen, der an seinen beiden Enden in der Nähe des Kugelbeginns die Einspannung der-Membrane trägt ..Subject Hydro - pneumatic pressure accumulator with two membranes' Ball-like pressure accumulators, which are composed of two halves of the ball, have the disadvantage, because !.) is the connection of the two halves on the largest circle of the sphere and therefore the joint is exposed to the greatest stress. -By The present invention overcomes this disadvantage. It is based on the fact that the diameter of the pressure accumulator is reduced when it is used with a cylindrical Game provides without changing the overall content. The largest diameter c thus becomes smaller than that of a spherical pressure accumulator. Content. Such However, pressure accumulators have the disadvantage that they are spherical under internal overpressure Want to take on shape: The welded connection is also subject to tensile stress additionally absorb a bending load. If the two halves of the Accumulator are connected by a weld, it must still be taken into account that the membrane, which is clamped in the cylindrical part of the accumulator, is endangered by the heat of the weld, in order to eliminate these defects proposed the pressure accumulator with a cylindrical part made of spherical halves with a cylindrical approach manufacture and to provide with an inner ring, which at both ends in the constraint of the diaphragm near the start of the sphere.
Die Schweißnaht kann in an: sich bekannter Weise mit dem Innenring zusammen verschweißt werden. Bei dieser Art- Druckspeicher kann man .den Innenraum für die Gasfüllung und den Raum zwischen Membrane , und Stahlmantel für die Flüssigkeit verwenden oderumgekehrt: Diese Art der Druckspeicher vermeidet die Nachteile einer kugeligen sowie die einer kugelig-zylindrischen Ausführung. Die Schweißnaht ist durch den geringeren Durchmesser dieser Art von Durchmesser gegen,-über denkugelgen Durchmessern geringer belastet. Das wirtschaftliche Optimum ist erreicht, wenn der Inhalt des zylindrischen Teils ca.--gleich dem Inhalt der beiden. Kugelschalenhälften ist. In Fig, 1 ist der -Erfindungegegenstand gezeichnet. Die kugeligen . und die zylindrischen Partien des Behälters sind ersichtlich.The weld seam can in a known manner with the inner ring are welded together. With this type of pressure accumulator one can .the interior for the gas filling and the space between the membrane and the steel jacket for the liquid use or vice versa: This type of pressure accumulator avoids the disadvantages of a spherical and spherical-cylindrical designs. The weld is due to the smaller diameter of this type of diameter against, -over think ballgen Diameters less loaded. The economic optimum is achieved when the Contents of the cylindrical part approximately - equal to the contents of the two. Spherical shell halves is. In Fig, 1 the object of the invention is drawn. The spherical ones . and the cylindrical parts of the container can be seen.
Die Kugelhälften 1 und 2 sind durch die Schweißnaht 3 miteinander verbunden. Vor dem Zusammenschweißen werden in den Rehälter die Membranen 4 und 5 eingelegt, die durch den zylindrischen Ring 6 gehalten werden.,. Beim Zusammenschweißender beidem Kugelhälften 1 und 2 wird gleichzeitig der Ring 6 angeschweißt. Der Behälter hat die Öffnungen 7 und 8 zur Zuführung der Flüssigkeit, während der innere Raum 9 mit Gas vorgespannt ist. Die Gasfüllung geschieht in an sich bekannter Weise durch die Öffnung 10, In der gezeigten Ausführung sind die Öffnungen 7 und 8 mit der Pumpe 11 verbunden, Die Zeitung 12 geht zum Verbraucher. Die Scheiben 13 und 14 verhindern den Austritt der Membranen 4 und 5 -durch die Öffnungen 7 und 8, wenn der Druckspeicher ganz von Flüssigkeit entleert ist und die Membranen durch den Gasdruck gegen die Wandung des Behälters gedrückt werden®The halves of the ball 1 and 2 are connected to one another by the weld 3 tied together. Before they are welded together, the membranes 4 and 5 inserted, which are held by the cylindrical ring 6.,. When welding together The ring 6 is welded onto both halves of the ball 1 and 2 at the same time. The container has the openings 7 and 8 for feeding the liquid, while the inner space 9 is biased with gas. The gas filling is done in a manner known per se the port 10, In the embodiment shown, the ports 7 and 8 are with the pump 11 connected, the newspaper 12 goes to the consumer. The discs 13 and 14 prevent the exit of the membranes 4 and 5 - through the openings 7 and 8, if the pressure accumulator is completely emptied of liquid and the membranes by the gas pressure against the Wall of the container are pressed®
