Definitions
- the invention relates to a switching valve for the transmission of fluids, in particular for filling gas tanks.
- a switching valve in the design of a quick-connect coupling, wherein a housing having a fluid inlet and a fluid outlet and a plurality of valves are provided to ensure a secure seal.
- These valves are switched after applying the quick-connect coupling by turning a control lever in a certain predetermined order, first the exhaust valve is opened, then with further movement of the control lever, the collets are closed and finally the inlet valve is opened.
- the control lever is in this case via an eccentric shaft with the sliding sleeve for the application of the collets and with a sealing piston in engagement, which also releases the fluid inlet after the connection of the plug-in coupling.
- a vent valve is provided which allows the pressure equalization before removing the plug-in coupling, so that there is no risk of recoil even at high pressures.
- the outlet valve acts like a check valve.
- Another switching valve is off GB-A-1 521 639 known, which is to be regarded as the closest prior art.
- the invention has for its object to provide a switching valve of the type mentioned, which enables easy handling with a compact design and prevents contamination or fluid reflux by targeted venting.
- the proposed switching valve with slide is particularly suitable for use in the filling of industrial gas tanks, resulting in a simple and compact design, since the switching valve with attached control valve for pressure-controlled actuation of a pivot lever is designed concise concise and stable and thus integrated to save space in filling can be.
- the pivot lever provided in this case is preferably designed with a translation, i. with different lever lengths, so that a powerful operation of the valve actuation valve is achieved.
- the piston of the control valve is preferably connected via a bolt with the pivot lever, which is mounted in particular on a pivot axis in an intermediate housing. This results in a sensitive control, in particular when the piston surface cross sections of the piston are formed on the inlet / outlet side the same.
- this construction achieves a simple connection to the valve housing, as well as a compact connection with a bypass line for controlling the pressure-controlled control valve.
- a switching valve 10 In Fig. 1 and 2 an embodiment of a switching valve 10 is shown.
- the switching valve 10 has a tubular housing 11 with a plurality of housing parts 11a, 11b and 11c screwed together, the right housing part 11c acting as inlet area 12 and the left area as outlet area 13 for the forwarding of the fluid to be transferred.
- the inlet region 12 has an adapter 14, to which a fluid line 12 'for supplying the fluid to be transferred is connected.
- the connection adapter 14 can be configured correspondingly in adaptation to the fluid volume to be transferred, in particular to the respective desired passage cross-sections.
- a corresponding adapter 14 'for the discharge line 13' In the outlet region 13, a corresponding adapter 14 'for the discharge line 13' is provided.
- a bypass line 15 is interposed, which thus acts on a mounted on the housing 11 control valve 20 with the inlet pressure and the outlet pressure, as explained below.
- a check valve 25 is arranged, which in the in Fig. 2 illustrated closed position under spring pressure against a valve seat 26 seals to prevent backflow from the outlet 13.
- a slide valve 27 which can be moved axially along the central axis and move a movement here to the right a sealing washer 24 of a vent valve 35.
- the vent valve 35 and the slide switch 27 are in this case actuated by pivoting a pivot lever 50, since this is coupled to the slide switch 27, here for example by positive engagement via an annular groove 29th
- an inlet valve 45 with an associated valve seat is furthermore arranged toward the inlet region 12.
- the inlet valve 45 is also axially displaceable by the pivot lever 50 and by the coupling with the slide valve 27, since the slide valve 27 on the rightward movement of the sealing disc 24 of the vent valve 35 in the manner of a sequence control and a valve spool 47 of the inlet valve 45 from the Shown here closing position shifts into the open position, so that the inflowing from the inlet portion 12 fluid through the hollow valve spool 47 and a passage in the sealing washer 24 and the tubular slide valve 27 can flow to the outlet 13, since in this case also the check valve 25 by the filling pressure ( from the refueling system or other pressure source / Beglallpumpe) is pressed into the open position.
- control valve 20 is mounted on the housing 11 (with inlet valve 45, venting valve 35 and check valve 25 inserted therein) via an intermediate housing 19.
- a piston 21 (circumferentially sealed) is used, which is acted upon by a spring 22 and thus pressed into the right position shown here.
- the two end faces, which are exposed to the respective pressure in the bypass line 15, are preferably dimensioned equal, so that the piston 21 can move sensitively with the slightest pressure differences between right (inlet) and left (outlet) side.
- the threshold pressure is determined by the spring 22.
- the piston 21 is also coupled by a bolt 53 with the pivot lever 50 so that the control valve 20 pressure-controlled via the slide 27, the valves 35 and 45 can operate.
- the sealing disc 24 and the slide valve 27 and valve slide 47 separate slightly in the axial direction, so that the pressure can degrade to a pressure compensation chamber 44, which is formed as a paragraph-like annular space in a gradation on the housing part 11c around the sealing washer 24 around.
- the lever lengths are different on both sides of the pivot axis 52, eg here in the ratio 3: 1, so that a power transmission is achieved.
- a powerful actuation of the slide 27 and the valves coupled thereto can be achieved, even with a relatively small construction of the control valve 20 (or diameter of the piston 21).
- This translation can be relatively easily changed eg by replacing the intermediate housing 19 and the pivot axis 52 mounted therein or extension of the pivot lever 50, for example in adaptation to the respective filling pressures.
- the switching valve 10 with attached control valve 20 can be used variably, especially the conversion, if necessary, by means of screws 60 (see. Fig. 1 ) can be carried out quickly.
- the bypass line 15 can also be connected to the adapters 14, 14 'or directly to the respective inlet / outlet region 12, 13, of the housing 11, in order to improve the compactness of the pressure-controlled valve.

Die Erfindung betrifft ein Schaltventil für die Übertragung von Fluiden, insbesondere zum Befüllen von Gastanks.The invention relates to a switching valve for the transmission of fluids, in particular for filling gas tanks.
Bei Übertragungssystemen mit derartigen Schaltventilen soll eine sichere Übertragung eines Fluids von einer Druckquelle, beispielsweise von einer Betankungsanlage aus zu einem Gastank erreicht werden. Besonders wichtig ist hierbei die einfache Bedienbarkeit und Sicherheit gegen Kontaminationen. So wird in der

Demzufolge liegt der Erfindung die Aufgabe zugrunde, ein Schaltventil der eingangs genannten Art zu schaffen, das bei kompaktem Aufbau eine einfache Handhabung ermöglicht und eine Kontamination bzw. einen Fluid-Rückfluss durch gezielte Entlüftung unterbindet.Accordingly, the invention has for its object to provide a switching valve of the type mentioned, which enables easy handling with a compact design and prevents contamination or fluid reflux by targeted venting.
Diese Aufgabe wird gelöst durch ein Schaltventil gemäß den Merkmalen des Anspruches 1. Bevorzugte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a switching valve according to the features of claim 1. Preferred developments of the invention are subject of the dependent claims.
Das vorgeschlagene Schaltventil mit Schieber eignet sich insbesondere für den Einsatz bei der Befüllung von Industrie-Gastanks, wobei sich eine einfache und kompakte Bauweise ergibt, da das Schaltventil mit aufgesetztem Steuerventil zur druckgesteuerten Betätigung eines Schwenkhebels kleinbauend und stabil ausgebildet ist und somit platzsparend in Befüllanlagen integriert werden kann.The proposed switching valve with slide is particularly suitable for use in the filling of industrial gas tanks, resulting in a simple and compact design, since the switching valve with attached control valve for pressure-controlled actuation of a pivot lever is designed kleinbauend and stable and thus integrated to save space in filling can be.
Der hierbei vorgesehene Schwenkhebel ist bevorzugt mit einer Übersetzung ausgelegt, d.h. mit unterschiedlichen Hebellängen, so dass eine kraftvolle Betätigung des Schiebers zur Ventilbetätigung erzielt wird. Der Kolben des Steuerventils ist dabei bevorzugt über einem Bolzen mit dem Schwenkhebel verbunden, der insbesondere an einer Schwenkachse in einem Zwischengehäuse gelagert ist. Hierdurch ergibt sich eine feinfühlige Steuerung, insbesondere wenn die Kolbenflächenquerschnitte des Kolbens ein-/auslassseitig gleich ausgebildet sind. Zudem wird durch diese Bauweise eine einfache Anbindung an das Ventilgehäuse erreicht, ebenso eine kompakte Verbindung mit einer Bypassleitung zur Ansteuerung des druckgesteuerten Steuerventils.The pivot lever provided in this case is preferably designed with a translation, i. with different lever lengths, so that a powerful operation of the valve actuation valve is achieved. The piston of the control valve is preferably connected via a bolt with the pivot lever, which is mounted in particular on a pivot axis in an intermediate housing. This results in a sensitive control, in particular when the piston surface cross sections of the piston are formed on the inlet / outlet side the same. In addition, this construction achieves a simple connection to the valve housing, as well as a compact connection with a bypass line for controlling the pressure-controlled control valve.

In
Im Gehäuseteil 11a ist ein Rückschlagventil 25 angeordnet, das in der in
Im hier rechten Gehäuseteil 11c ist zum Einlassbereich 12 hin weiterhin ein Einlassventil 45 mit einem zugeordneten Ventilsitz angeordnet. Das Einlassventil 45 ist ebenfalls durch den Schwenkhebel 50 und durch die Koppelung mit dem Schaltschieber 27 axial verschiebbar, da der Schaltschieber 27 über die Nach-Rechts-Bewegung der Dichtscheibe 24 des Entlüftungsventils 35 in Art einer Folgesteuerung auch einen Ventilschieber 47 des Einlassventils 45 aus der hier gezeigten Schließstellung in die Öffnungsstellung verschiebt, so dass das vom Einlassbereich 12 zuströmende Fluid durch den hohlen Ventilschieber 47 und einen Durchlass in der Dichtscheibe 24 sowie den rohrförmigen Schaltschieber 27 zum Auslass 13 hin fließen kann, da hierbei auch das Rückschlagventil 25 durch den Befülldruck (von der Betankungsanlage oder einer sonstigen Druckquelle/Befüllpumpe) in die Öffnungsstellung gedrückt wird.In the right-hand housing part 11c, an
Wie vorstehend angeführt, ist auf dem Gehäuse 11 (mit darin eingesetztem Einlassventil 45, Entlüftungsventil 35 und Rückschlagventil 25) über ein Zwischengehäuse 19 das Steuerventil 20 aufgesetzt. In diesem ist ein Kolben 21 (umfangsseitig abgedichtet) eingesetzt, der von einer Feder 22 beaufschlagt ist und somit in die hier gezeigte rechte Position gedrückt wird. Die beiden Stirnseiten, die dem jeweiligen Druck in der Bypassleitung 15 ausgesetzt sind, werden dabei bevorzugt gleich bemessen, so dass sich der Kolben 21 bei geringsten Druckunterschieden zwischen rechter (Einlass-) und linker (Auslass-) Seite feinfühlig verschieben kann. Der Ansprechschwellendruck wird dabei durch die Feder 22 bestimmt.
Der Kolben 21 ist zudem durch einen Bolzen 53 mit dem Schwenkhebel 50 gekoppelt, so dass das Steuerventil 20 druckgesteuert über den Schieber 27 die Ventile 35 und 45 betätigen kann.As stated above, the
The
Ist im hier rechten Einlassbereich 12 der Druck höher als auf der Auslassseite 13, wie dies beim Beginn und Andauer der Befüllung der Fall ist, so wird zunächst der Kolben 21 auf die hier linke Seite hin verschoben und der Schieber 27 durch den (entgegen dem Uhrzeigersinn schwenkenden) Schwenkhebel 50 nach rechts verschoben. Dabei wird das Entlüftungsventil 35 geschlossen zu und das Einlassventil 45 aufgedrückt. Wie oben beschrieben, fließt das Fluid dann durch den hohlen Schieber 27 hindurch, drückt das Rückschlagventil 25 auf und strömt über den Auslassbereich 13 zum zu befüllenden Gastank.If the pressure in this case is higher in the right-
Wird dann zum Ende der Befüllung (bei gefülltem Gastank oder Abschalten der Füllpumpe) der Druck auf der Auslassseite größer als der Einlassdruck, so geht der Kolben 21 in die hier gezeigte Ausgangsstellung (rechter Anschlag) zurück, wobei der Schwenkhebel 50 den Schieber 27 wieder nach links bewegt macht, so dass das Einlassventil 45 geschlossen wird, aber dabei das Entlüftungsventil 35 geöffnet wird, um den Zwischenraum zwischen Einlassventil 45 und dem zwischenzeitlich (wegen des fehlenden Einlassdruckes) ebenfalls geschlossenen Rückschlagventil 25 zu entlüften. Bei diesem Verschwenken (im Uhrzeigersinn) des Schwenkhebels 50 wird der Schaltschieber 27 nach links verschoben, so dass sich auch die Dichtscheibe 24 des Entlüftungsventils 35 aus dem Dichteingriff lösen kann. Hierbei trennen sich die Dichtscheibe 24 und die Schaltschieber 27 und Ventilschieber 47 in Axialrichtung geringfügig voneinander, so dass sich der Druck zu einem Druckausgleichsraum 44 hin abbauen kann, der als absatzartiger Ringraum in einer Abstufung am Gehäuseteil 11c um die Dichtscheibe 24 herum ausgebildet ist.Then, at the end of the filling (with filled gas tank or shutdown of the filling pump), the pressure on the outlet side greater than the inlet pressure, the
Beim vorstehend beschriebenen Öffnen des Entlüftungsventils 35 durch den Schaltschieber 27 strömt daher noch anstehendes, im Schaltventil "gefangenes" Druckmedium über den Druckausgleichsraum 44 zu einer Entlüftungsbohrung 43 am Gehäuseteil 11c, um z.B. in einen Rückführschlauch oder Tank oder bei unbedenklichen Fluiden in die Atmosphäre zu münden.In the above-described opening of the
Hinsichtlich des Schwenkhebels 50 sei darauf hingewiesen, dass die Hebellängen beidseits der Schwenkachse 52 unterschiedlich sind, z.B. hier etwa im Verhältnis 3:1, so dass eine Kraftübersetzung erzielt wird. Dadurch kann eine kraftvolle Betätigung des Schiebers 27 und der damit gekoppelten Ventile erzielt werden, selbst bei relativ kleiner Bauweise des Steuerventils 20 (bzw. Durchmesser des Kolbens 21). Diese Übersetzung kann z.B. durch Austausch des Zwischengehäuses 19 und der darin gelagerten Schwenkachse 52 oder Verlängerung des Schwenkhebels 50 relativ einfach verändert werden, z.B. in Anpassung an die jeweiligen Befülldrücke. Damit ist das Schaltventil 10 mit aufgesetztem Steuerventil 20 variabel einsetzbar, zumal der Umbau, falls erforderlich, mittels Schrauben 60 (vgl.
