Description
DEUTSCHESGERMAN
Die Erfindung betrifft ein Entlüftungsventil für Flüssigkeitsvorratsbehälter, vorzugsweise von hydraulischen Grubenstempeln. Derartige Ventile bieten hinsichtlich ihrer Betriebssicherheit keine besonderen Probleme. Schwierig jedoch wird es dann, wenn die Möglichkeit besteht, daß der Behälter bisweilen eine andere als seine aufrechte Betriebsstellung einnimmt, weil dann durch das Ventil nicht mehr Luft, sondern Flüssigkeit austritt, Gedacht ist hier z. B. an Brennstofftanks für Fahrzeuge. Bei diesen besteht nach Umstürzen bei Unfällen die Gefahr des Inbrandgeratens durch ausfließenden Brennstoff. Das Austreten von Flüssigkeit muß ebenfalls verhindert werden bei hydraulischen Grubenstempeln, die zwar im Einsatz aufrecht stehen, jedoch beim späteren Herausziehen 'umstürzen.The invention relates to a vent valve for liquid storage containers, preferably hydraulic ones Pit stamps. Such valves do not offer any special ones with regard to their operational safety Problems. However, it becomes difficult when there is a possibility that the container sometimes has a other than its upright operating position, because then through the valve no more air, but Liquid leaks out. B. on fuel tanks for vehicles. These persist If you fall over in the event of an accident, there is a risk of burns caused by leaking fuel. The exit Liquid must also be prevented in the case of hydraulic pit rams that are in the Insert stand upright, but overturn when pulling out later.
Gemäß der Erfindung wird diese Aufgabe durch einen doppelkegelförmigen Ventilsitz und einen hanteiförmigen Ventilverschlußkörper gelöst, dessen der Flüssigkeit zugewandter Teil als dichtender Ventilteil ausgebildet und leichter als der äußere Teil ist. In der normalen aufrechten Behälterstellung wird der Ventilverschlußkörper durch sein Eigengewicht nach unten gezogen, der nicht abdichtende Teil liegt auf der Sitzfläche auf, läßt also Luft aus- oder eintreten. Wird der Behälter jedoch gekippt, so rutscht der schwere Teil — sobald der Kippwinkel einen vom Kegelöffnungswinkel abhängigen Winkel überschreitet ■— noch weiter nach außen und zieht also den leichteren, abdichtenden Ventilteil in seine Sitzfläche hinein. Die Kipprichtung ist völlig beliebig, da der schwere Ventilteil den abdichtenden Ventilteil in jedem Fall in seine Sitzfläche zieht und damit den Austritt von Flüssigkeit verhindert.According to the invention, this object is achieved by a double conical valve seat and a dumbbell-shaped valve closure body, the The part facing the liquid is designed as a sealing valve part and is lighter than the outer part. In the normal upright container position, the valve closure body is by its own weight pulled down, the non-sealing part rests on the seat, so air can enter or exit. However, if the container is tilted, the heavy part slips - as soon as the tilting angle is off The angle dependent on the cone opening angle exceeds ■ - even further outwards and thus pulls the lighter, sealing valve part into its seat. The direction of tilt is completely arbitrary, since the heavy valve part pulls the sealing valve part in each case into its seat and thus the Prevents liquid from escaping.
Die Zeichnung veranschaulicht ein erfindungsgemäßes Ausführungsbeispiel, und zwar zeigtThe drawing illustrates an embodiment according to the invention, namely shows
Abb. 1 den Oberteil eines aufrecht stehenden Behälters mit Entlüftungsventil,Fig. 1 the top of an upright container with a vent valve,
Abb. 2 den gleichen Behälter um 90° gekippt.Fig. 2 tilted the same container by 90 °.
Der Flüssigkeitsbehälter ist mit 1 bezeichnet und trägt einen festen Deckel 2. In eine zentrale Öffnung ist ein doppelkegelförmiger Ventilsitz 3 eingeschraubt. Auf den Ventilsitz 3 ist eine Schutzkappe 4 aufgeschoben. Der hanteiförmige Ventilverschlußkörper besteht aus einem abdichtenden halbkugelförmigen Teil 5 mit einem Schaft 6. Auf dem Schaft ist ein ebenfalls halbkugelförmiger Teil 7 mit einer Mutter 8 befestigt. Der Teil 7 ist schwerer als der Teil 5.The liquid container is denoted by 1 and has a fixed cover 2. In a central opening a double conical valve seat 3 is screwed in. A protective cap 4 is pushed onto the valve seat 3. The dumbbell-shaped valve closure body consists of a sealing hemispherical Part 5 with a shaft 6. A likewise hemispherical part 7 with a nut 8 is located on the shaft attached. Part 7 is heavier than part 5.
In der Stellung gemäß Abb. 1 kann Luft an dem Teil 7 vorbei durch Entlüftungsnuten 9 oder -bohrungen 10 aus- oder eintreten. Zu diesem Zweck besitzt die Kappe 4 eine Bohrung 11. Wird der Behälter 1 nun gekippt, so zieht der als Gegengewicht wirkende Teil 7 den abdichtenden Ventilteil 5 in seinen Sitz.In the position according to Fig. 1, air can past the part 7 through venting grooves 9 or bores 10 exit or enter. For this purpose, the cap 4 has a bore 11. If the container 1 is now tilted, the part 7 acting as a counterweight pulls the sealing valve part 5 into its seat.

Die wenige Flüssigkeit, die eventuell noch kurz vor dem Schließvorgang ausgetreten ist, bleibt in der Kappe 4 stehen und fließt nach Wiederaufrichten des Behälters 1 in diesen zurück.The little liquid that may have escaped shortly before the closing process remains in the Cap 4 stand and flows back into the container 1 after it has been erected again.
Der Teil 5 besteht zweckmäßig aus Leichtmetall oder Kunststoff, der Teil 7 aus Stahl, damit die Gewichtsdifferenz zwischen den beiden Teilen genügend groß ist.The part 5 is expediently made of light metal or plastic, the part 7 of steel, so that the weight difference is big enough between the two parts.
Die Erfindung ist vorzugsweise gedacht für die Flüssigkeitsvorratsbehälter hydraulischer Grubenstempel. Der Raubvorgang erfolgt nämlich gewöhnlich derart, daß der Stempel nach dem Drucklosmachen von ferne mittels eines Seiles oder einer Kette vorgezogen wird. Beim Umstürzen des Stempels besteht dann stets die Gefahr, daß die Druckflüssigkeit durch die Entlüftungsbohrungen ausläuft. Dieser Gefahr kann nunmehr durch Einbau des erfindungsgemäßen Entlüftungsventils begegnet werden.The invention is preferably intended for the liquid storage containers of hydraulic pit rams. The robbery process is usually carried out in such a way that the stamp after depressurization is pulled forward remotely by means of a rope or chain. If the stamp is overturned, there is then there is always the risk that the hydraulic fluid will leak through the vent holes. This danger can now be countered by installing the vent valve according to the invention.
