Abstract

A common shut-off valve (11) is provided in a first outlet (12) in the gas channel (10) inside the connecting rail (6) between the gas vessels (2-4). The gas outlet parts (14-16) of the vessels are connected directly to the rail without any intermediate piping. The support rail (5) combines with the connecting rail to form a mounting frame for the vessels.

Description

Die Erfindung betrifft ein Druckgastanksystem mit mindestens zwei Gasbehältern gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a compressed gas tank system with at least two gas containers according to the preamble of claim 1.

Es ist bekannt, Druckgase in Gasflaschen zu lagern und zu transportieren. Die beispielsweise zylinderförmigen Behälter sind mit einem Gas gefüllt, welches sich auf einem gegenüber Umgebungsdruck erhöhten Druck befindet. Die Gasflaschen weisen üblicherweise an einer Seite ein Absperrventil auf, an welches z.B. ein Druckregler anschließbar ist, mit dessen Hilfe das Gas aus der Flasche entnommen werden und dessen Druck auf einen gewünschten Entnahmedruck vermindert werden kann. Üblicherweise ist auch eine Sicherheitsvorrichtung bestehend aus einer sogenannten Schmelzsicherung vorgesehen sein, welche bei unzulässiger Übertemperatur des Tanks öffnet, einen Druckabbau erlaubt und damit einen Schutz gegen Überdruck darstellt. Bei Bedarf an größeren Gasmengen werden derartige Gasflaschen z.B. in Serie geschaltet.It is known to store compressed gases in gas cylinders and to transport.
