Description
Die Erfindung bezieht sich auf eine Umschaltvorrichtung für die Zufuhr eines unter Druck stehenden Fluidums, wie Butan, Propan od. dgl., zu einem Verbraucher, z. B. einem Brenner, von mehreren Quellen für das Fluidum mit einem beweglichen Organ, das unter dem Druck des Fluidums steht und eines der Ventile in geöffnetem und die übrigen Ventile so lange in geschlossenem Zustand hält, bis der Druck der an das geöffnete Ventil angeschlossenen Quelle unter einen vorbestimmten Wert sinkt, um dann das Öffnen eines anderen Ventils und damit den Anschluß einer weiteren Quelle herbeizuführen.The invention relates to a switching device for the supply of a pressurized one Fluid, such as butane, propane or the like. To a consumer, e.g. B. a burner, from multiple sources for the fluid with a movable organ that is under the pressure of the fluid and one of the Holds the valve in the open state and the remaining valves in the closed state until the pressure is released of the source connected to the open valve drops below a predetermined value, in order to then reduce the Open another valve and thus connect another source.
Aufgabe der Erfindung ist es, eine Umschaltvorrichtung der eingangs genannten Art so weiter auszubilden, daß sie gleichzeitig die Einhaltung eines bestimmten Druckes des Fluidums in der Zuleitung zum Verbraucher sicherstellt und dadurch die Anordnung gesonderter Druckminderventile erübrigt.The object of the invention is to further develop a switching device of the type mentioned at the beginning, that they simultaneously maintain a certain pressure of the fluid in the supply line to Ensures consumers and thus eliminates the need to arrange separate pressure reducing valves.
Ein wesentliches Merkmal der Erfindung besteht darin, daß das bewegliche Organ aus einer Membran od. dgl. besteht, die auf ihrer einen Seite vom Druck der Umgebung und durch eine tarierte Feder und auf ihrer anderen Seite vom Druck des Fluidums in der Zuleitung zum Verbraucher beaufschlagt ist und der ein Nocken mit einer mit den Ventilen zusammenwirkenden Leitfläche zugeordnet ist, die so abgeschrägt ist, daß sie während der Vorbewegung der Membran bei Druckabsenkung nacheinander auf die Ventile auftrifft und sie öffnet.An essential feature of the invention is that the movable organ consists of a membrane Od. Like. Is on one side of the pressure of the environment and by a tared spring and on its other side is acted upon by the pressure of the fluid in the supply line to the consumer and the a cam is associated with a guide surface which interacts with the valves and which is thus bevelled is that they are successively on the during the advancement of the membrane when the pressure drops Valves hits and she opens.
Im Zusammenhang mit den Zeichnungen wird gezeigt werden, daß die erfindungsgemäße Vorrichtung nicht nur selbsttätig umschaltet, sondern auch als Druckminderventil arbeitet; sie sorgt dafür, daß in der Zuleitung zum Verbraucher ein konstanter Druck aufrechterhalten wird. Außerdem ist es bei der Konstruktion gemäß der Erfindung möglich, mehr als zwei Ventile nebeneinander vorzusehen und dementsprechend mehr als zwei Gasquellen anzuschließen. Die bis jetzt bekannten Umschaltvorrichtungen dieser Art sind nur zum Anschluß an zwei Gasquellen geeignet.In connection with the drawings it will be shown that the device according to the invention not only switches over automatically, but also works as a pressure reducing valve; it ensures that in the supply line to the consumer a constant pressure is maintained. Plus, it's in the construction possible according to the invention to provide more than two valves side by side and accordingly connect more than two gas sources. The switching devices of this type known up to now are only suitable for connection to two gas sources.
In besonders vorteilhafter Weise ist der Nocken mit der Leitfläche zwecks Veränderung der Reihenfolge der von ihm zu öffnenden Ventile in bezug auf die Ventile verstellbar.

beispielsweise durch Achsen 14 (Fig. 2) an einem Teil 15 angelenkt. Dieser Teil 15 ist selbst mittels eines Ringes 16 und einer Mutter 17 an einer Membran 18 befestigt, die im Gehäuse 1 angeordnet ist, d. h. genauer zwischen dem die Kammer 6 begrenzenden Teil des Gehäuses und einem Deckel 19. Die Verbindung beider Teile erfolgt z. B. durch Schraubenbolzen 20. Auf der Deckelseite der Membran 18 ist eine tarierte Feder 21 vorgesehen, die bestrebt ist, die Membran 18 in Richtung der Kammer 6 zu drücken. Der Deckel 19 läuft in einem zylindrischen Teil 22 aus, der eine Kappe 23 trägt. Die Kappe 23 ist mit einem Finger 24 versehen, der in einen Schlitz 25 im zylindrischen Teil 22 des Deckels 19 eingreift und die Kappe so gegen axiale Verschiebung sichert, jedoch eine beschränkte Drehung zuläßt.articulated to a part 15, for example by means of axles 14 (FIG. 2). This part 15 is itself by means of a Ring 16 and a nut 17 attached to a membrane 18 which is arranged in the housing 1, d. H. more accurate between the part of the housing delimiting the chamber 6 and a cover 19. The connection both parts takes place z. B. by bolts 20. On the cover side of the membrane 18 is a tared spring 21 is provided, which tends to press the membrane 18 in the direction of the chamber 6. The cover 19 ends in a cylindrical part 22 which carries a cap 23. The cap 23 is with a finger 24 which engages in a slot 25 in the cylindrical part 22 of the cover 19 and which Cap so secures against axial displacement, but allows limited rotation.
Die Kappe ist mit einem hohlzylindrischen vorspringenden Ansatz 26 versehen, in den eine Stange 27 eingreift. Diese Stange 27 ist über eine Stift-Schlitz-Kupplung 28 mit der Kappe 23 verbunden, und zwar so, daß sie sich im Innern des Ansatzes 26 in axialer Richtung frei bewegen kann.The cap is provided with a hollow cylindrical projecting extension 26 into which a rod 27 intervenes. This rod 27 is connected to the cap 23 via a pin-and-slot coupling 28, in such a way that it can move freely in the interior of the extension 26 in the axial direction.
Die Stange 27 durchsetzt den Ring 16, in den gegebenenfalls eine Dichtung 29 eingeschaltet ist. An ihrem unteren Ende trägt die Stange 27 einen Nocken 30, dessen Leitfläche zwei Absätze bzw. abgestufte Oberflächen α und b aufweist, deren Ebenen einen rechten Winkel mit der Achse der Stange 27 einschließen. Die Nockenstange 27 ist in bezug auf den Ring 16 mit Hilfe eines Stiftes 31 festgelegt.The rod 27 passes through the ring 16, in which a seal 29 is inserted if necessary. At its lower end, the rod 27 carries a cam 30, the guide surface of which has two shoulders or stepped surfaces α and b , the planes of which enclose a right angle with the axis of the rod 27. The cam rod 27 is fixed with respect to the ring 16 by means of a pin 31.
In dem Gehäuse 1 ist eine in die Kammer 6 mündende Zuleitung 32 zum Verbraucher vorgesehen.In the housing 1 a feed line 32 which opens into the chamber 6 is provided to the consumer.
Wie in Fig. 2 dargestellt, ist in dem über der Membran 18 liegenden Raum 33 eine Anzeigevorrichtung vorgesehen. Diese Anzeigevorrichtung besteht in dem veranschaulichten Beispiel aus einem Hebel 34, der um eine Achse 35 schwenkbar ist und auf den eine Feder 36 derart einwirkt, daß sein einer Arm 37 auf der Membran 18 aufliegt. Der andere Arm 38 des Hebels 34 trägt eine Anzeigeplatte, die bei Absenkung der Membran 18 hinter einem in dem Deckel 19 vorgesehenen Fenster 39 erscheint.As shown in FIG. 2, in the space 33 lying above the membrane 18 there is a display device intended. In the example illustrated, this display device consists of a lever 34 which is pivotable about an axis 35 and acts on a spring 36 in such a way that its one arm 37 on the membrane 18 rests. The other arm 38 of the lever 34 carries an indicator plate, which when lowered the membrane 18 appears behind a window 39 provided in the cover 19.
Die Wirkungsweise der erfindungsgemäßen Umschaltvorrichtung ist sehr einfach. In dem dargestellten Beispiel ist — wie bereits gesagt — angenommen, daß zwei Leitungen 2 und 3, d. h. zum Beispiel zwei Propan- oder Butangasflaschen angeschlossen sind. Die Zahl der anschließbaren Quellen kann jedoch beliebig sein.The mode of operation of the switching device according to the invention is very simple. In the illustrated Example is - as already said - assumed that two lines 2 and 3, i. H. for example two Propane or butane cylinders are connected. The number of sources that can be connected can, however, be arbitrary be.
Solange der Verbraucher kein Gas entnimmt, befinden sich die verschiedenen Bauelemente der Vorrichtung in der in Fig. 1 gezeigten Stellung. Bei Inbetriebnahme des Verbrauchers wird das unter Druck stehende Fluidum durch die Zuleitung 32 angefordert. Durch den im Innern der Kammer 6 entstehenden Unterdruck wird unmittelbar eine Verformung, d. h. Absenkung der Membran 18 unter Entspannung der Feder 21 herbeigeführt. Dabei nimmt die Membran 18 die Stange 27 und den Nocken 30 mit. Der Absatz α kommt am Kopf 40 der Ventilstange 11 zur Anlage und stößt sie entgegen der Wirkung der Feder 9 nach unten. Dabei öffnet sich das Ventil 7 so lange, bis der Druck in der Kammer 6, der auf die eine Seite der Membran 18 wirkt, dem Gegendruck der Feder 21 entspricht. Die Auslegung der Feder 21 ist somit für den Druck in der Kammer 6 maßgebend. Die Umschaltvorrichtung arbeitet somit nach Art eines Druckminderventils. Infolgedessen bleibt der Druck in der Zuleitung 32 zum Verbraucher unabhängig von Temperaturschwankungen, denen die Gasquellen unterworfen sind, konstant.As long as the consumer is not drawing gas, the various components of the device are in the position shown in FIG. 1. When the consumer is put into operation, the pressurized fluid is requested through the supply line 32. The negative pressure created in the interior of the chamber 6 immediately causes a deformation, ie lowering of the membrane 18 with the spring 21 being released. The membrane 18 takes the rod 27 and the cam 30 with it. The paragraph α comes to rest on the head 40 of the valve rod 11 and pushes it downward against the action of the spring 9. The valve 7 opens until the pressure in the chamber 6, which acts on one side of the membrane 18, corresponds to the counter pressure of the spring 21. The design of the spring 21 is therefore decisive for the pressure in the chamber 6. The switching device thus works in the manner of a pressure reducing valve. As a result, the pressure in the supply line 32 to the consumer remains constant regardless of temperature fluctuations to which the gas sources are subjected.
Sobald der Druck in der an die Leitung 2 angeschlossenen Flasche unter dem durch die tarierte Feder 21 und die Bemessung der Membran 18 bestimmten, von der Umschaltvorrichtung konstant gehaltenen Verbraucherdruck sinkt, vermag ein Öffnen des Ventils 7 nicht mehr eine Druckerhöhung im Innern der Kammer 6 herbeizuführen und die Membran in der veranschaulichten Lage zu halten. Sie senkt sich infolgedessen unter Entspannung der Feder 21 und nimmt den Nocken 18 mit. Der Nocken gelangt somit mit seinem Absatz b am Kopf 41 der Ventilstange 12 in Anlage, so daß infolge der Absenkung nunmehr das Ventil 8 geöffnet wird. Es stellt sich daraufhin ein neues Gleichgewicht zwischen dem Druck der tarierten Feder 21, die jetzt bei Öffnung des Ventils 8 in entspanntem Zustand ist, und demAs soon as the pressure in the bottle connected to the line 2 falls below the consumer pressure determined by the tared spring 21 and the dimensioning of the membrane 18 and kept constant by the switching device, opening the valve 7 is no longer able to bring about a pressure increase inside the chamber 6 and holding the membrane in the illustrated position. As a result, it lowers with relaxation of the spring 21 and takes the cam 18 with it. The cam thus comes into contact with its shoulder b on the head 41 of the valve rod 12, so that the valve 8 is now opened as a result of the lowering. There is then a new equilibrium between the pressure of the tared spring 21, which is now in the relaxed state when the valve 8 opens, and the

Der Verbraucher wird somit jetzt aus der an die Leitung 3 angeschlossenen Flasche mit einem vergleichsweise geringeren Druck gespeist.ao counteracting gas pressure in the chamber 6. The consumer is now out of the line 3 connected bottle is fed with a comparatively lower pressure.

as Hebel 34, dessen Anzeiger 38 bei Inbetriebnahme der Reserveflasche hinter dem Fenster 39 erscheint. Wenn die Bedienungsperson das Erscheinen dieses Anzeigers bemerkt, kann sie die Kappe 23 kurzerhand um 180° verdrehen, wodurch über die Stift-Schlitz-Kupplung 28 der Nocken 30 mitgeführt wird, bis der Absatz α mit dem Kopf 41 der Ventilstange 12 in Berührung gelangt. Durch diese Umschaltung wird bisherige als Reserveflasche arbeitende, an die Zuleitung 3 angeschlossene Flasche zum Hauptgaslieferanten. Die ursprüngliche, nunmehr erschöpfte Hauptgasflasche kann gegen eine neue volle Flasche ausgetauscht werden. Infolge der Umschaltung des Nokkens 30 ist gleichzeitig eine Druckerhöhung in der Kammer 6 auf den normalen Arbeitsdruck erreicht.The lever 34, the indicator 38 of which appears behind the window 39 when the reserve bottle is put into operation. If the operator notices the appearance of this indicator, he can turn the cap 23 by 180 ° without further ado, whereby the cam 30 is carried along via the pin-and-slot coupling 28 until the shoulder α comes into contact with the head 41 of the valve rod 12. As a result of this switchover, the cylinder that was previously working as a reserve cylinder and connected to the supply line 3 becomes the main gas supplier. The original, now exhausted main gas bottle can be exchanged for a new, full bottle. As a result of the switching of the cam 30, a pressure increase in the chamber 6 to the normal working pressure is achieved at the same time.
Wie in Fig. 4 dargestellt, steuert die mit dem Nokken verbundene Stange 27 bei ihrer Axialbewegung ein bewegliches Anzeigeorgan, eine koaxial zur Stange 27 liegende Scheibe 42 od. dgl., die drehbar in einem Lager 43 der Kappe 23 montiert ist. Diese Scheibe 42 wird über ein Führungsorgan in Umdrehung versetzt, z. B. ein von der Stange 27 getragenes Plättchen 44 mit einer Schraubenführung 46. Das Plättchen 44 durchsetzt dabei eine in der Mitte der Scheibe 42 angebrachte Öffnung 45 von entsprechendem Querschnitt. Infolge der schraubenartigen Form dieses Plättchens 44 führt die Scheibe 42 bei axialer Bewegung der Stange 27 beispielsweise eine Vierteldrehung in ihrem Lager aus. Die Scheibe 42 ist beispielsweise mit gefärbten Sektoren 47, 47 a versehen. Diese Sektoren sind von außen durch Fenster 48, Sehlöcher od. dgl. beispielsweise in Pfeilform sichtbar, die in eine das Lager 43 anschließende Scheibe 49 gelocht sind. Wenn die Scheibe 42 infolge einer axialen Steuerbewegung der Stange 27 eine Viertelumdrehung ausführt, wechselt der Pfeil 48 die Farbe.As shown in Fig. 4, the rod 27 connected to the cam controls its axial movement a movable display member, a coaxial to the rod 27 lying disc 42 or the like. That rotatable in one Bearing 43 of the cap 23 is mounted. This disk 42 is set in rotation via a guide member, z. B. a plate 44 carried by the rod 27 with a screw guide 46. The plate 44 passes through an opening 45 made in the center of the disk 42 and having a corresponding cross section. As a result of the helical shape of this plate 44, the disk 42 guides during axial movement the rod 27, for example, a quarter turn in its bearing. The disk 42 is for example provided with colored sectors 47, 47 a. These sectors are from the outside through windows 48, sight holes od. The like. Visible, for example, in the form of an arrow, which is perforated in a disk 49 adjoining the bearing 43 are. When the disk 42 as a result of an axial control movement the rod 27 executes a quarter turn, the arrow 48 changes color.
Durch das Plättchen 44 od. dgl. kann natürlich auch jedes andere bewegliche Anzeigeorgan angetriefen werden, z. B. ein sich hinter einer transparenten Abschlußscheibe drehendes Plättchen in Pfeilform.By means of the plate 44 or the like, any other movable display element can of course also be accessed be e.g. B. a rotating behind a transparent cover plate plate in the shape of an arrow.
Die Nockenstange 27 könnte natürlich das bewegliche Anzeigeorgan auch direkt mitnehmen oder antreiben. Es könnte der Fall eintreten, daß die Bedienungsperson versehentlich die an die Zuleitung 2 ange-The cam rod 27 could of course also take along or drive the movable display element directly. It could happen that the operator inadvertently connects to the supply line 2.
schlossene erschöpfte Gasflasche löst, ohne zuvor den Nocken 30 aus der in Fig. 1 dargestellten Lage um 180: geschwenkt zu haben. Dann fließt natürlich das aus der an die Zuleitung 3 angeschlossenen vollen Flasche in die Kammer 6 eintretende Gas über das in Öffnungsstellung befindliche Ventil 7 und die Zuleitung 2 ins Freie ab. Um dies zu verhindern, sind zweckmäßigerweise in den Zuleitungen 2 und 3 Rückschlagventile angeordnet, die einen Austritt der Gase aus der Kammer 6 über die Zuleitungen 2 und 3 ins Freie verhindern.closed exhausted gas bottle releases without first having pivoted the cam 30 from the position shown in FIG. 1 by 180 :. Then, of course, the gas entering the chamber 6 from the full bottle connected to the supply line 3 flows through the valve 7 in the open position and the supply line 2 to the outside. In order to prevent this, check valves are expediently arranged in the supply lines 2 and 3, which prevent the gases from escaping from the chamber 6 via the supply lines 2 and 3 to the outside.
