Description

Gegenstand des Hauptpatentes ist eine Einrichtung zur Anzeige von Undichtheiten an Lagerbehältern für Flüssigkeiten oder Gase, die mit einer Blase aus lagerstoffestem, gasdichtem und flexiblem Kunststoff ausgekleidet oder umhüllt sind und bei denen an den Zwischenraum zwischen der Kunststoffblase und der starren Behälterwand eine Vakuumpumpe zur Erzeugung eines bestimmten Unterdruckes in diesem Zwischenraum angeschlossen ist und ein Druckmesser zur Überwachung des Unterdruckes vorgesehen ist. Hierbei ist die ständig mit dem Wandzwischenraum verbunden; Vakuumpumpe mit einer Einrichtung zur druckabhängigen Einsatzregelung versehen, welche den Druck im Wandzwischenraum, soweit er infolge unvermeidlicher und unschädlicher kleiner Undichtheiten absinkt, selbsttätig nerha b eines bestimmten Unterdruckbereiches (unterdrucksollwert) hält, wobei Mittel vorgesehen sind, die eine Verzögerung oder ein Ausbleiben der Herbeiführung des Unterdrucksollwertes im Wandzwischenraum als Kriterium einer Leckage anzeigen. The subject of the main patent is a device for displaying Leakage on storage containers for liquids or gases with a bladder Lined or encased from storage material, gas-tight and flexible plastic are and where the space between the plastic bladder and the rigid Container wall a vacuum pump to generate a certain negative pressure in this Intermediate space is connected and a pressure gauge for monitoring the negative pressure is provided. Here, the is constantly connected to the space between the wall; Vacuum pump provided with a device for pressure-dependent application control, which the pressure in the space between the wall, insofar as it is smaller as a result of inevitable and harmless Leakage drops automatically within a certain negative pressure range (negative pressure setpoint) holds, means are provided that a delay or failure to bring about the negative pressure setpoint in the wall gap as Show the criterion of a leak.

Die Erfindung betrifft eine weitere Ausgestaltung der Erfindung nach dem Hauptpatent, die dessen Lösungsprinzip unter Ausnutzung der an sich bekannten Tatsache, daß ein Wandzwischenraum mit starren Begrenzungswandungen die Verwendung sowohl von Überdruck als auch von Unterdruck als Überwachungsgröße ermöglicht, verallgemeinert und seinen Anwendungsbereich erweitert. The invention relates to a further embodiment of the invention the main patent, which its solution principle using the known per se The fact that a wall space with rigid boundary walls is the use allows both overpressure and underpressure as a monitoring variable, generalized and expanded its scope.

Die Erfindung besteht in der Anwendung der Einrichtung nach dem Hauptpatent bei einem an sich bekannten doppelwandigen Lagerbehälter mit starrer-Innen- und Außenwand, dessen stabiler Wandzwischenraum ein Arb'eiten der: Einrichtung entweder mit einem positiven oder einem'- negativen' Druckabweichungssollwert (Über- oder Unterdruckanzeige) gestattet. The invention consists in the application of the device according to the main patent in a known double-walled storage container with rigid inner and Outer wall, the stable wall space between which the: facility either with a positive or a 'negative' pressure deviation setpoint (over- or Vacuum indicator).

Wird mit einer Unterdruckanzeige gearbeitet, so kann die Druckerzeugungs- und Anzeigevorrichtung ähnlich eingerichtet sein wie bei der an einem Behälter mit Kunststoffblase angebrachten Einrichtung nach dem Hauptpatent. Bei einer Überdruckanzeige, wie sie nur bei doppelwandigen Behältern mit starren Wandungen möglich ist, wird auf entsprechende automatische Art und Weise im Wandzwischenraum oder Bezugsraum ein kleiner Gasüberdruck (Luftdruck) erzeugt und zum Zwecke der Leckanzeige überwacht. If a vacuum display is used, the pressure generation and display device be set up similarly to that of a container with Plastic bladder-attached device according to the main patent. If there is an overpressure display, as it is only possible with double-walled containers with rigid walls in a corresponding automatic manner in the wall space or reference space a small gas overpressure (air pressure) is generated and monitored for the purpose of leak detection.
