Description
Die Erfindung betrifft ein Bodenventil für Behälter zum Transport von flüssigem Gefahrgut, das mittels des Ventilkörpers mit dem Behälter verbunden ist, durch den eine Durchgangsöffnung führt, die durch einen Ventilteller verschließbar ist, der in geschlossener Stellung abdichtend am Rand der Durchgangsöffnung anliegt, wobei zwischen Ventilteller und dem Rand eine Dichtung angeordnet ist und wobei der Ventilteller mittels einer Betätigungseinheit in seiner Position veränderbar ist, die einen Hebelarm aufweist, der durch eine seitliche Ausnehmung in der Durchgangsöffnung geführt ist.The invention relates to a bottom valve for containers Transport of liquid dangerous goods by means of the valve body is connected to the container through which a through hole leading through a valve disk is lockable in the closed position sealingly abuts the edge of the through opening, wherein A seal is arranged between the valve plate and the edge is and wherein the valve plate by means of an actuating unit its position can be changed, which has a lever arm through a lateral Recess is guided in the through hole.
Behälter zum Transport von flüssigem Gefahrgut die vorzugsweise im Straßenverkehr als Tankfahrzeug, im Schienenverkehr als Kesselwagen und auch im Containerverkehr eingesetzt werden, verfügen über ein Bodenventil, das üblicherweise auf einem Auslaufflansch aufgeschraubt, der im Sohlenbereich des Behälters angeordnet ist.Containers for the transport of liquid dangerous goods which are preferred in road traffic as a tanker, in rail traffic as tank wagons and also in container traffic are used have a bottom valve that usually screwed onto an outlet flange, which is arranged in the sole region of the container.
Aus der EP 0430 664 B 1 ist eine Ventilanordnung für Flüssigkeiten und Gas bekannt, bei der eine Welle tangential zum Ventildurchlaß im Ventilkörper angeordnet ist an der ein flaches kreisförmiges Ventilverschlußelement festgelegt ist. Das Verschlußelement wird mittels der Welle aus seiner den Ventildurchlaß abdeckenden Position bewegt. Der Arm der das Verschlußelement mit der Welle verbindet ist durch eine Öffnung im Ventilkörper im Bereich des Ventildurchlaßes geführt.From EP 0430 664 B1 is a valve arrangement for Liquids and gas are known where a wave is tangential arranged for valve passage in the valve body is a flat circular valve closure element is set. The closure element is by means of the shaft from its covering the valve passage Position moved. The arm of the closure element connects to the shaft through an opening in the valve body performed in the area of the valve passage.
Nachteilig ist bei dieser Konstruktion, daß die Spiralfeder, die an einem Ende der Welle angeordnet ist, und für das sichere Schließen des Ventils sorgt, relativ leicht mit den teilweise aggressiven Gefahrstoffen in Berührung gelangen kann, da diese durch die Öffnung für den Arm in den Wellenkanal gelangen und von dort, bedingt durch die horizontale Ausrichtung des Wellenkanals leicht weiter in den Bereich der Spiralfeder gelangen können. Durch Verdrängungen der Schmiermittel bzw. durch Korrosion wird dann die Funktionstüchtigkeit des Ventils beeinträchtigt.The disadvantage of this construction is that the spiral spring, which is arranged at one end of the shaft, and ensures the safe closing of the valve, relative easily with the partially aggressive hazardous substances in Can come into contact as this through the opening for the arm get into the wave channel and from there, conditionally due to the horizontal alignment of the wave channel slightly further into the area of the spiral spring can. By displacing the lubricants or through corrosion then the functionality of the valve.
Außerdem stellt die außen am Tank liegende Feder einen Kompromiß hinsichtlich passiver Sicherheit zugunsten der Reinigungsfähigkeit der Ventilkonstruktion dar.In addition, the spring on the outside of the tank provides one Compromise in terms of passive safety in favor the cleanability of the valve construction.
Aus der GB 922,389 ist weiterhin ein Bodenventil für Schüttgutbehälter bekannt, das gewisse konstruktive Merkmale mit den Ventilen für flüssige Gefahrstoffe aufweist. Dieses ist derart ausgestaltet, daß durch den Druck des Schüttgutes das Bodenventil geschlossen bleiben soll.From GB 922,389 is still a bottom valve for Bulk containers known, the certain constructive Features with the valves for liquid hazardous substances having. This is designed such that the Pressure of the bulk material, the bottom valve remains closed should.
Dazu ist ein Federmechanismus vorgeschlagen worden, durch dessen Spannung ein sicherer Verschluß erreicht werden soll. Problematisch ist dabei jedoch die Ausgestaltung der Mechanik, da deren Teile mit dem Schüttgut in Berührung kommen, wodurch oftmals deren Funktionstüchtigkeit beeinträchtigt wird. Letztlich ist durch die bekannten Ventile die passive Sicherheit nicht gewährleistet und die Wartungs- und damit die Reinigungsfähigkeit nicht gegeben.A spring mechanism has been proposed achieved a secure closure by its tension shall be. However, the design is problematic the mechanics, since their parts with the bulk material come into contact, which often makes them functional is affected. Ultimately is through the known valves do not guarantee passive safety and the maintenance and thus the cleanability not given.
