Abstract
Description
Die vorliegende Erfindung betrifft Behälter für kryogenes Fluid und insbesondere Vorrichtungen zum Verschließen solcher Behälter und zu ihrem Anschließen an Außenrohrleitungen jener Art, die eine einstückige Unterbaugruppe, die allgemein die Form einer Scheibe aufweist und mindestens zwei Fluiddurchgangskanäle definiert, gemäß den Merkmalen des Oberbegriffs von Anspruch 1 definiert.The present invention relates to container for cryogenic Fluid and in particular devices for closing such container and connecting them on external pipelines of the kind that is one piece Subassembly which is generally in the form of a disc and defined at least two fluid passageways, according to the characteristics of the Preamble of claim 1 defined.
Eine solche Vorrichtung wird in der Schrift US-A-4 956 975 schematisch dargestellt.Such a device is in the Document US-A-4 956 975 is shown schematically.
Die bekannten Vorrichtungen zum Verschließen und Anschließen der Behälter für kryogenes Fluid bestehen aus einer mechanisch geschweißten Anordnung aus einer Verschlussplatte und maschinell bearbeiteten und in der Regel durch Schweißen in in der Verschlussplatte herausgearbeiteten Öffnungen befestigten Anschlussteilen. Diese Technik ist aufgrund der Anzahl der verschiedenen herzustellenden, zu lagernden und zusammenzubauenden Teile und aufgrund des großen Ausmaßes an Ausschuss durch Probleme bei der Bearbeitung und beim Schweißen der Herstellungsmaterialien, in der Regel rostfreie Austenitstähle, besonders mühselig.The known devices for closing and Connect the container for cryogenic Fluid consist of a mechanically welded arrangement of a closure plate and machined and usually by welding in the Closure plate machined openings attached connecting parts. This technique is due to the number of different, parts to be stored and assembled and due to the large extent of rejects Problems with processing and welding the manufacturing materials, usually stainless austenite steels, particularly laborious.
Aufgabe der vorliegenden Erfindung ist die Bereitstellung eines vereinfachten Aufbaus, der es gestattet, den Großteil dieser Probleme zu überwinden und die Herstellungs- und Montagekosten wesentlich zu reduzieren.Object of the present invention is to provide a simplified structure that allows most of it to overcome these problems and significantly reduce manufacturing and assembly costs.
Dazu schlägt die Erfindung eine Vorrichtung mit einer einstückigen Unterbaugruppe aus gegossenem rostfreiem Stahl vor, die üblicherweise durch Wachsausschmelzgießen hergestellt wird und einen Hauptteil aufweist, der eine eine Verbindungsebene bildende Fläche besitzt.To this end, the invention proposes a device one piece Cast stainless steel subassembly before, which is usually by lost wax casting is produced and has a main part which forms a connecting plane area has.
Nach einem besonderen Merkmal der Erfindung wird die einstückige Unterbaugruppe aus einer Legierung aus rostfreiem Austenitstahl gegossen, die aus mindestens 16%, in der Regel zwischen 16 und 18,5%, Chrom und mindestens 10%, in der Regel zwischen 10 und 13,5%, Nickel besteht und in der Flüssigphase eine Ferritmenge von über 2%, vorzugsweise nicht über 6%, besitzt.According to a special feature of the Invention becomes the one-piece Subassembly made of an alloy made of austenitic stainless steel poured from at least 16%, usually between 16 and 18.5%, Chromium and at least 10%, usually between 10 and 13.5%, nickel exists and in the liquid phase a ferrite amount of over 2%, preferably not over 6%.
Des Weiteren hat die Erfindung einen Behälter für kryogenes Fluid, insbesondere Flüssigsauerstoff, für Sauerstofftherapie Zuhause zum Gegenstand, der mit einer solchen Vorrichtung ausgestattet und in der Regel mit zwei atmosphärischen Erhitzern versehen ist, die mit Flüssigkeits- und Gasauslasskanälen der Vorrichtung verbunden sind.Furthermore, the invention has one container for cryogenic Fluid, in particular liquid oxygen, for oxygen therapy At home to the object equipped with such a device and usually with two atmospheric Heater is provided with the liquid and gas outlet channels Device are connected.
Weitere Vorteile und Merkmale der vorliegenden Erfindung gehen aus der folgenden Beschreibung einer zur Veranschaulichung angeführten, aber keineswegs einschränkenden Ausführungsform unter Bezugnahme auf die beigefügten Zeichnungen hervor; es zeigen darin:Other advantages and features of present invention will become apparent from the following description for illustrative purposes, but in no way restrictive embodiment with reference to the accompanying drawings forth; it shows:
