Abstract

Das am Tank (10) vorgesehen Überdruckventil (13) kann durch den Druck einer Steuerleitung (32) auch dann geöffnet werden, wenn sein Ansprechdruck nicht erreicht ist. Die Steuerleitung (32) ist über eine Reihenschaltung aus einem Ventil (19), das auf Temperaturerhöhungen im Tank (10) rea­ giert und einem temperaturabhangigen Absperrorgan (20), das auf Brandtemperaturen in der Nähe des Tanks reagiert mit einer drucklosen Auslaßleitung (16) oder mit einer Druck­ quelle verbunden. Wenn ein Brand eintritt, erhöhen sich Tem­ peratur, Flüssigkeitsstand und Druck im Tank (10) und durch die erhöhte Außemtemperatur öffnet das Absperrorgan. Nur wenn beide Bedingungen erfüllt sind, veranlaßt die Reihen­ schaltung das Abblasen von Gas. Die normale Funktion des Überdruckventils (13) wird nicht beeinträchtigt. Es besteht die Möglichkeit, den Tank (10) bis zur maximalen Füllhöhe von 98% des Tankvolumens zu befüllen, ohne befürchten zu müssen, daß im Brandfall die Füllhöhe von 98% überschrit­ ten wird. The pressure relief valve (13) provided on the tank (10) can then opened by the pressure of a control line (32) if its response pressure is not reached. The Control line (32) is a series connection of one Valve (19) that reacts to temperature increases in the tank (10) yawed and a temperature-dependent shut-off device (20), that responds to fire temperatures near the tank with an unpressurized outlet line (16) or with a pressure source connected. When a fire occurs, tem temperature, liquid level and pressure in the tank (10) and through the increased outside temperature opens the shut-off device. Just if both conditions are met, the rows start circuit blowing off gas. The normal function of the Pressure relief valve (13) is not affected. It exists the possibility of the tank (10) up to the maximum fill level of 98% of the tank volume to fill without fear must in the event of fire exceed the fill level of 98% will.
