Slcherheita-Schnellkupplung für DruckbehälterSafety quick coupling for pressure vessels

Die Erfindung betrifft eine Sicherheits-Schnellkupplung zum Befüllen und Entleeren von Silobehältern und zusätzlicher Luftan^chluß zwischen Luftbedienungsleitungen von SiIo-Aufbauien und Silo-Anhängern.The invention relates to a safety quick coupling for filling and emptying silo containers and additional air connection between air supply lines of silo bodies and silo trailers.

Bei den vorhandenen Schnellkupplungen nach dem System Storz, die an allen Silo-Aufbauten und Anhängern im Einsatz sind, haben sich in jüngster Zeit schwere Unfälle durch Lösen von Blindkupplungen uead von Festkupplungen bei druckbeaufscnlagten Tanks ereignet. Vorhandene Druckprüfeinrichtungen auf den Behältern (oder an den Festkupplungen selbst, meist kleine Absperrhähne) wurden nicht benutzt oder waren unbrauchbar.With the existing Storz system quick couplings, which are used on all silo structures and trailers, serious accidents have recently occurred due to blind couplings and fixed couplings coming loose on pressurized tanks. Existing pressure testing devices on the containers (or on the fixed couplings themselves, usually small shut-off valves) were not used or were unusable.

Die neue "Sicherheits-Schnellkupplung" arbeitet im Prinzip wie eine Storz-Kupplung, im Gegensatz dazu kann sich der Blinddeckel nach e'ner ca. 90° Drehung nur soweit abheben, daß ein evtl. Druck im Tank gefahrlos entweichen kann und erst nach einer zweiten, entgegengesetzten ca. 90°-Drehung kann der Blinddeckel ganz abgenommen werden.The new "safety quick coupling" works in principle like a Storz coupling, in contrast to this, the blind cover can only be lifted off after a 90° turn to the extent that any pressure in the tank can escape safely and only after a second, opposite turn of approx. 90° can the blind cover be completely removed.

Die Festkupplungshälfte besteht aus 2 übereinanderliegendenThe fixed coupling half consists of 2 superimposed Labyrinten, an denen die Einführungen für die HaltepratzenLabyrinths where the inlets for the holding claws

entgegengesetzt angeordnet sind. Die vorhandenen Haltepratzen in kurzer Ausführung.are arranged opposite each other. The existing holding claws are in a short version.

Der Blinddeckel hat nur ein Labyrint mit einseitiger EinführungThe blind cover has only one labyrinth with one-sided insertion

Ausführung.Execution.

Die Vorteile liegen darin, daß bei einem unbeabsichtigen Verdrehen einer Blindkupplung an einem druckbeaufschlagten Behälter die eine Kupplungshälfte nicht wegfliegt. Weiterhin besteht keine Gefahr der Verstopfung, da die Kupplungen den Druck über den vollen Rohrquerschnitt der jeweiligen Kupplungsgröße abblasen läßt.The advantages are that if a blind coupling on a pressurized container is accidentally twisted, one half of the coupling does not fly away. Furthermore, there is no risk of blockage, as the couplings allow the pressure to be released over the full pipe cross-section of the respective coupling size.

Sicherheitsverschluß für Druckbehälter, der aus einem am Bebälter angebrachten Verschlußstutzen und aus ekuan auf diesen Stutzen aufsetzbaren Blinddeckel besteht, bei dem der Verschlußstutzen als Festkupplung ausgebildet ist, die zum Anschluß einer Förderleitung dient, wobei F^stkupplung und Blinddeckel mit parallel zu ihrer Achse verlaufenden, starren Haltepratzen versehen sind, die in koaxiale Ringnuten eingreifen, dadurch gekennzeichnet, daß in der Festkupplung (1) zwei nebeneinander angeordnete Ringnuten (10,11) vorgesehen sind, die zum Einschieben der Haltepratzen (6, 7) des Blinddeckels (3; für jede Pratze zwei um etwa 90° versetzt zueinander angeordnete öffnungen (14,15) aufweisen, während sich im Blinddeckel (3) eine Ringnut für die ebenfalls starren Haltepratzen (4, S) der Festkupplung (1) befindet und für jede Haltepratze (4, 5) der Testkupplung (1) eine Öffnung zum Einschieben vorgesehen ist, und daß die Haltepratzen (6,T) des Blinddeckels (3) langer sind als die Haltepratzen (4,5) der Festkupplung (1).
Z Sicherheitsverschluß nach Anspruch 1, dadurch gekennzeichnet, daß an der Festkupplung (1) und am Blinddeckel (3) jeweils zwei um 180° versetzt zueinander angeordnete Haltepratzen (4 bis T) angebracht sind.1. Safety closure for pressure vessels, which consists of a closure nozzle attached to the vessel and a blind cover which can be placed on this nozzle, in which the closure nozzle is designed as a fixed coupling which serves to connect a conveyor line, the fixed coupling and blind cover being provided with rigid holding claws which run parallel to their axis and engage in coaxial annular grooves, characterized in that in the fixed coupling (1) two annular grooves (10, 11) arranged next to one another are provided which have two openings (14, 15) arranged offset by approximately 90° to one another for inserting the holding claws (6, 7) of the blind cover (3), while in the blind cover (3) there is an annular groove for the likewise rigid holding claws (4, 5) of the fixed coupling (1) and an opening for insertion is provided for each holding claw (4, 5) of the test coupling (1), and that the holding claws (6, 7) of the blind cover (3) are longer than the retaining claws (4,5) of the fixed coupling (1).
Z Safety closure according to claim 1, characterized in that two retaining claws (4 to T) arranged offset by 180° to one another are attached to the fixed coupling (1) and to the blind cover (3). 3. Sicherheitsverschluß nach Anspruch 1 und 2, dadurch gekennzeichnet, daß die Haltepratzen (4 bis T) an ihren freien Enden mit Abwinklungen (8) zum Eingriff in die Ringnuten versehen sind.3. Safety closure according to claim 1 and 2, characterized in that the holding claws (4 to T) are provided at their free ends with angled portions (8) for engagement in the annular grooves.
