KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Absperrventile für die Behälter hochgespannter und verflüssigter Gase, ζ. B. die Transportflaschen für flüssige Kohlensäure, besitzen ausnahmslos einen Uebelstand. Dieser Uebelstand besteht darin, dafs ein Theil des Gases durch die Stopfbüchse entweicht.The shut-off valves for the containers of high pressure and liquefied gases, ζ. B. the Transport bottles for liquid carbon dioxide invariably have a drawback. This The disadvantage is that part of the gas escapes through the stuffing box.
Bei längerem Transport kommt es vor, dafs die Behälter einem solchen Rütteln ausgesetzt sind, dafs sich der Ventilschaft lockert und sich infolge dessen das Ventil von seinem Sitz abhebt. Alsdann ist selten eine Stopfbüchsenpackung dicht genug, um dem Druck des Gases ausreichenden Widerstand entgegenzusetzen. Dasselbe gilt in noch höherem Grade beim Gebrauch der Behälter. Es ist nämlich üblich geworden, zwischen das Absperrventil und die Verbrauchsstelle einen Druckminderapparat einzuschalten. Dieser Apparat hat nur dann einen Zweck, wenn das Absperrventil in geöffnetem Zustand verbleiben kann. Das Oeffnen und Absperren soll der Druckminderapparat selbstthätig bewirken. Während nun in diesem Falle das Absperrventil offen bleibt, hat man sich während der ganzen Zeit ausschliefslich auf die Dichtheit der Stopfbüchsenpackung zu verlassen. Die Erfahrung hat aber gezeigt, dafs auch die besten Verpackungsmaterialien diesen Zweck nur unvollkommen erfüllen.In the case of longer transport, the containers may be exposed to such shaking are that the valve stem loosens and as a result the valve lifts from its seat. Then a stuffing box packing is seldom tight enough to offer sufficient resistance to the pressure of the gas. The same is true to an even greater extent when using the containers. It has become customary to place between the shut-off valve and the consumption point to switch on a pressure reducer. This apparatus only has then a purpose when the shut-off valve can remain in the open state. That The pressure reducing device should automatically open and shut off. While now in this case the shut-off valve remains open, one has exclusively during the whole time rely on the tightness of the gland packing. Experience has shown, however, that the best packaging materials are also suitable fulfill this purpose only imperfectly.
Durch die vorliegende Erfindung wird diesem Uebelstand abgeholfen.This disadvantage is remedied by the present invention.
In beiliegender Zeichnung ist ein Absperrventil in zwei verschiedenen Austührungsformen dargestellt. Fig. 1 ist der Längsschnitt der einen, Fig. 2 der Längsschnitt der anderen Ausführungsform.In the accompanying drawing there is a shut-off valve in two different designs shown. Fig. 1 is the longitudinal section of one, Fig. 2 is the longitudinal section of the other Embodiment.
Gleiche Buchstaben bezeichnen in beiden Figuren gleiche Theile, α ist das in den Behälter dicht eingeschraubte Ventilgehäuse, b ist ein beweglich angeordnetes Ventil, welches in der Zeichnung als geschlossen dargestellt ist. Durch Hochschrauben wird das Ventil in üblicher Weise geöffnet und durch Niederschrauben geschlossen, d dient zum Anpressen der Stopfbüchsenpackung. Bei Fig. 2 ist d ganz im Innern des Ventilgehäuses angeordnet. c und f sind Verschlufskappen.The same letters denote the same parts in both figures, α is the valve housing screwed tightly into the container, b is a movably arranged valve, which is shown as closed in the drawing. The valve is opened in the usual way by screwing it up and it is closed by screwing it down, d is used to press the stuffing box packing. In Fig. 2 d is arranged entirely inside the valve housing. c and f are caps.
Das Ventil selbst weicht von den bekannten Gonstructionen nicht ab.The valve itself does not deviate from the known construction.
Neu ist dagegen die aufschraubbare Verschlufskappe f, welche, ohne den Auslafsstutzen zu umschliefsen, die Ventilstopfbüchse luftdicht abschliefst. What is new, however, is the screw-on closure cap f, which closes the valve stuffing box airtight without enclosing the outlet nozzle.
Während des Transports sind beide Verschlufskappen fest aufgeschraubt. Soll aus dem Behälter Gas entnommen werden, so werden zunächst beide Verschlufskappen entfernt und der Auslafsstutzen mit der Verbrauchsstelle verbunden. Nachdem nun das Ventil geöffnet worden ist, wird, wenn ein Druckminderapparat Anwendung findet, die Verschlufskappey wieder fest auf das Ventilgehäuse aufgeschraubt. Wenn nun die Stopfbüchsenpackung ihren Dienst versagt, so ist doch ein Verlust von Gas unmöglich geworden. ! Both caps are screwed on tightly during transport. If gas is to be withdrawn from the container, both closure caps are first removed and the outlet nozzle connected to the point of consumption. After the valve has now been opened, if a pressure reducing device is used, the closure cap is screwed firmly back onto the valve housing. If the gland packing fails to function, a loss of gas has become impossible. !
