Description

Flasechenventi@lfe, wie sie als Absperrorgane, z. B. für Sauerstofflaschen, üblich sind, lassen beim ersten Öffnen; plötzlich. einen starken Strom desi Gasibehälfierinhaltes. austreten. Durch den stoßartig ausströmenden Sauerstoff können in Reduzverventilen, welche auf -das Flaschenventil aufgeschraubt werden, oder an Gummipuffern, der Vene tile- selbst infolge der dort frei werdenden Kompressionswärme Aüsbrennungen eintreten., welche durch die Entzündung von Stoffen organischer . Natur eingeleitet werden.Flasechenventi @ lfe, as they are used as shut-off devices, e.g. B. for oxygen cylinders, are common to leave on first opening; suddenly. a strong stream of the gas content. step out. Due to the sudden outflow of oxygen, reducing valves, which are screwed onto the bottle valve, or on rubber buffers, the vein tile- even as a result of the heat of compression released there, burns occur., which by the inflammation of substances organic. Be initiated in nature.

Durch: Einbau einer erheblichen Drosselung mit einer Öffnung von höchstens i, mm2 Querschnitt zwsschen dem Druckbehälter und der gefährdeten Stelle wies Ventils kann diese Gefahr eTfindungsgemäß beseitigt und das, Ventil, ausbrennsicher gemacht werden.By: installing a significant throttling with an opening of at most i, mm2 cross-section between the pressure vessel and the endangered point pointed valve this danger can be eliminated according to the invention and the valve made burnout-proof will.

Man. kann z. B. unter der eigeiltlichen Sitzfläche des Flaschenventils eine Drosselscheibe mit einer sehr engen öffnung anondnen. Wird. das Ventil geöffnet, so bremst der enge Du.rchlaß dieser Drossel den Gasstoß, d. h. die plötzlich austretende und auf die gefährdeten Ventilsetellen aufprallende Gasmasse, auf einen gefahrlöserx Wert. Der Querschnitt dieser Drossel kam einen konstanten, Wert aufweisen und z:. B. vor dem eigentlichen e Ventilisitz angeordhet seine.Man. can e.g. B. under the seat area of the cylinder valve Fit a throttle disc with a very narrow opening. Will. the valve opened, so the tight opening of this throttle slows down the throttle, i.e. H. the suddenly emerging and gas mass impacting the endangered valve locations, on a hazard solverx Value. The cross-section of this choke came to have a constant, value and z :. B. in front of the actual valve seat.

Eine vorteilhaftere Lösung besteht darin, daß man die Wirkung der Drosselstelle mit forts,chreitenvder öffnung des: Ventilse verändert, und zwar erfindungsgemäß so, daß, sie nur während des ersten Teiles des. Ventilhubs wirksam isst, bei vollständig geöffnetem. Ventil aber ein wesentlich weiterer Kanalquerschnitt freigegeben isü.A more advantageous solution is that you can see the effect of the Throttle point with forts, stepping through the opening of the valve changed, according to the invention so that, at full, she only eats effectively during the first part of the valve stroke open. Valve, however, a much wider channel cross-section is released.

Eine zweckmäßige Ausführungsform dieses, Erfirndeungs@gedankens besteht in der Verlängerung, des Venti.lke,gels, durch einen zylindrischen Ansatz, der in die Ventilsitzbohrung oder sonst in eine zylindrische Bohrung des Zuflußkanals hineinragt. Bei dieserAnördnung wirdbeimÖffnen des vorher dicht geschlossenem- Ventils zunächsit. nur ein, schmaler Ringraum frei, der zw<eckm.äßs#g einen Querschnitt von unter i mm2, z. B. o;4 mm2, besitzt und während einest bestimmten Hubs, konstant bleibt und erst später bei weiterem Herausdrehen der Spindiel bis; auf nahezu: den vollen Querschnitt des Kanals freigegeben wird. Da die Gas@geschwiüdsgkeit, die Schallgeschwindigkeit in diesem Ringraum auch bei beliebiger Druckdifferenz nicht überschreiten kann, wird die maximale Menge dees zuerst austretenden Gases auf einige hundert Liter in der Stunde; bei Normaldruck gemessen, begrenzt.An expedient embodiment of this idea of the invention exists in the extension, of the valve, by a cylindrical attachment, which in the valve seat bore or otherwise protrudes into a cylindrical bore of the inflow channel. With this arrangement, the first step is to open the previously tightly closed valve. only a narrow annular space is free, which basically has a cross-section from below i mm2, e.g. B. o; 4 mm2, and remains constant during a certain stroke and only later with further turning out the spindle shaft up to; to almost: the full one Cross section of the channel is released. Since the gas @ speed, the speed of sound in this annulus, even with any pressure difference, cannot exceed the maximum amount of the gas that escapes first is a few hundred liters in the hour; measured at normal pressure, limited.

. Ein weiterer Vorteil dieser erfindungsgemäßen Maßnahme ist die Möglichkeit dien Feinregulierung durch eine Erweiterung des Ringraumes während der Phase der Ventilöffnung nach Zurückregung eines gewissen Hubweges der Ventilspindel, bevor der Querschnitt. des Kanals ganz freigegeben wird... Another advantage of this measure according to the invention is the possibility fine adjustment by widening the annulus during the phase of Valve opening after a certain stroke of the valve spindle has been returned before the cross section. of the channel is completely released.

Eine, erfindungsgemäße Anordnung sei an Hand der Fiuren näher beschrieben.An arrangement according to the invention will be described in more detail with reference to the figures.

Fig. i stellt ein Flaschenventil mit einem Gehäuse und einer Ventilbetätigunig üblicher Bauart dar. Das Gehäuse i mit dein konischen Gewinde?-. wird d in; eine nicht gezeichnete Stahlflasche eingeschrawbt und ermöglicht über den: Kanal, 3[ und 41 eine Verbindung zur Elitnahmestelle, falls die vom Handrad 8 betätigte und,durch Gummipuffer 9 nach außen gasidieht geführte Veneeilspindel 7 mit dem Verschluß- b:zw. Dichtungsstück 5, mit dem erfindungsgemäßen Ansatz 6 zurückgezogen wird.Fig. I shows a bottle valve with a housing and a valve actuator usual design. The housing i with your conical thread? -. will d in; one not drawn in steel bottle and made possible via the: channel, 3 [ and 41 a connection to the elite acceptance point, if the one operated by the handwheel 8 and through Rubber buffer 9 outwardly gas-fed veneer spindle 7 with the locking respectively. Sealing piece 5, with the approach 6 according to the invention is withdrawn.

Fig. 2 und 3 zeigen verschiedene Stellungen dies zurückgezogenen Verschlußatäckes. Sein Ansatyz 6, der bei geschlossener oder nur wenig geöffneter Stellung in dien Kanal 3t hsneinragt, läßte nur einen engen Ringraum. zwischen sich und der Wandlung des Kanals 2 frei. In diesem Ringraum herrscht beirn Öffnen des Ventils Schallgeschwindigkeit. Der Ringraum hat z. B. einen Gesamtquerschnitt vorn 0,4 mm.2. Unabhängig davon, wie hoch der Flaschendruck ist, kann die Schallgeschwindigkeit in diesem Ringraum rächt, überschritten werden:. Erst wenn Ader, am Ende sich etwas verjüngende Teil des Ansatzes in die Höhe des oberen: Randes vom Kanal 31 .gelangt, steigt das im der Zeiteinheit ausströmend-- Volum wesentlich am Bei ganz zurückgezogener Ventilspindel 7; ist der Kanalquerschnitt völlig frei.Fig. 2 and 3 show different positions of this retracted lock bag. His Ansatyz 6, which protrudes into the canal 3t when the position is closed or only slightly open, leaves only a narrow annular space. between itself and the conversion of channel 2 freely. When the valve opens, the speed of sound prevails in this annulus. The annulus has z. B. a total cross-section at the front 0.4 mm. 2. Regardless of how high the cylinder pressure is, the speed of sound in this annulus can be exceeded. Only when the vein, at the end of the slightly tapering part of the attachment, reaches the level of the upper edge of the channel 31 , does the volume flowing out in the unit of time increase significantly. the duct cross-section is completely free.
