Description

Ventil od. dgl. mit Antrieb durch ein Druckmittel und Anzeige der Endstellungen des Verschlußstücks mittels Schaltern Bei ferngesteuerten Ventilen u. dgl. ist es vielfach erforderlich, in den meisten Fällen wenigstens wilnsehenswert, an einem Korrunandostand die Bewegungen des Verschlußstücks und sein Ankommen in den Endstellungen für »AUF« und »ZU« überwachen zu können. Es sind Anordnungen bekannt, bei denen an der Ventilstange feste Anschläge angeordnet sind, durch die beim Schließen des Ventils ein Stromkreis geschlossen wird, so daß die Schließstellung durch Aufleuchten einer Lampe angezeigt wird.Valve or the like with drive by a pressure medium and display of the end positions of the closure piece by means of switches In remote-controlled valves and the like, it is often necessary, in most cases at least worth seeing, the movements of the closure piece and its arrival in the end positions on a corrugated stand to be able to monitor for "OPEN" and "CLOSED". Arrangements are known in which fixed stops are arranged on the valve rod, by means of which a circuit is closed when the valve is closed, so that the closed position is indicated by the lighting of a lamp.

Demgegenüber wird durch die Erfindung die Aufgabe gelöst, beide Endstellungen des Ventils, d. h. die Schließstellung und die Stellung des voll geöffneten Ventils, durch Betätigung von Schaltern anzuzeigen. Würde man bei einem solchen Ventil einfach die den Hubkolben mit dem Absperrkörper verbindende Kolbenstange zur Betätigung der Schalter nach außen führen, so würde dadurch die Bauhöhe des Ventils um die volle Hubhöhe vergrößert. Eine solche Vergrößerung der Bauhöhe des Ventils ist aber stets dann unerwünscht, wenn wenig Raum zur Verfügung steht, wie dies insbesondere beim Bergbau und auf Schiffen der Fall ist. Die Aufgabe, bei einem Ventil od. dgl. mit Antrieb durch ein Druckmittel, das auf einen durch eine Stange mit dem Verschlußstück verbundeneu Kolben od. dgL einwirkt, die Anzeige der Endstellungen des Verschlußstückes mittels Schaltern zu bewirken, die in Abhängigkeit von den Endstellungen desVerschlußstückesbetätigtwerden,ohnedaßdadurch die Bauhöhe des Ventils unzulässig vergrößert wird, wird erfindungsgemäß dadurch gelöst, daß die Kolbenstange an dem dem Kolben od. dgl. zugewandten Ende eine Längsbohrung aufweist, in der sich der Kopf einer Schaltstange für die Schalter mit soviel Spiel bewegt, daß er bei Erreichen der Endstellungen des Verschlußstücks in der entsprechenden Richtung mitgenommen wird und dadurch über die Schaltstange einen der Schalter betätigt. Dabei wird zweckmäßig während der Hubbewegung des Kolbens der Schaltstangenkopf durch abgestimmte Federn in Mittel-oder Ruhelage gehalten.In contrast, the object is achieved by the invention, both end positions of the valve, d. H. display the closed position and the position of the fully open valve by actuating switches. If one were to simply lead the piston rod connecting the reciprocating piston to the shut-off body to the outside for actuating the switch with such a valve, the overall height of the valve would be increased by the full stroke height. Such an increase in the overall height of the valve is always undesirable when there is little space available, as is the case in particular in mining and on ships. The task of a valve or the like with drive by a pressure medium acting on a piston or the like connected by a rod to the locking piece, to effect the display of the end positions of the locking piece by means of switches which are actuated depending on the end positions of the locking piece , without that the height of the valve is increased inadmissibly, is achieved according to the invention in that the piston rod at the end facing the piston od Reaching the end positions of the closure piece is taken along in the corresponding direction and one of the switches is thereby actuated via the switching rod. During the stroke movement of the piston, the switch rod head is expediently held in the central or rest position by coordinated springs.

Die Abbildung zeigt ein Ausführungsbeispiel der Erfindung in einem Längsschnitt.The figure shows an embodiment of the invention in one Longitudinal section.

Die Kolbenstange 1 besitzt zur Führung der Schaltstange 2 eine Längsbohrung 3, welche durch einen Ring 4 verschlossen ist. Der an der Schaltstange 2 befestigte Schaltnocken 5 betätigt die beiden Endschalter 6 a und 6 b, die die Signalabgabe zur Anzeige auslösen. Während der Hubbewegung des Kolbens 9 wird der Schaltnocken 5 durch die beiden Federn 7 und 8 in Mittel- oder Ruhestellung gehalten, in der keine Kontaktbetätigung erfolgt. Die Tiefe der Bohrung 3 ist um das Maß der beiden Schaltwege des Schaltnockens 5 kürzer als der Hub des Kolbens 9, so daß die Schaltstange 2 nur jeweils kurz vor dem Ende der jeweiligen Hubbewegung des Kolbens 9 um das vorbestimmte Maß gedrückt oder gezogen wird, um die Kontakte der Schalter 6a und 6b betätigen zu können.To guide the shift rod 2, the piston rod 1 has a longitudinal bore 3 which is closed by a ring 4. The switch cam 5 attached to the switch rod 2 actuates the two limit switches 6 a and 6 b, which trigger the signal output for the display. During the stroke movement of the piston 9 , the switching cam 5 is held by the two springs 7 and 8 in the central or rest position, in which no contact is actuated. The depth of the bore 3 is shorter than the stroke of the piston 9 by the amount of the two switching paths of the switching cam 5 , so that the switching rod 2 is pushed or pulled by the predetermined amount only shortly before the end of the respective stroke movement of the piston 9 to operate the contacts of switches 6a and 6b.

Die gezeichnete Stellun ' g des Kolbens 9 führt bei weiterer Abwärtsbewegung7zur Mitnahme der Schaltstange 2 nach unten und damit zur Betätigung des Schalters 6b, der die Schließstellung des Verschlußstücks direkt durch Schauzeichen oder Lampe oder ein akustisches Signal anzeigt oder mit Fernübertragung beispielsweise eine Lampe aufleuchten läßt.The drawn Stellun 'g of the piston 9 results in further Abwärtsbewegung7zur entrainment of the shift rod 2 downwardly and thus to actuate the switch 6b indicating the closed position of the closing member directly through shop sign or lamp, or audible signal, or can be illuminated with long-distance transmission such as a lamp.

Bei Einleitung des öffnungsvorganges bewegt sich der Kolben 9 nach oben, der Schaltnocken 5 wird durch seine Federn 7 und 8 in die MitteHage gebracht, wodurch der Kontakt der Endstellung zurückgeht und die Anzeigezeichen verschwinden oder erlöschen. Der' Schalter 6a wird erst betätigt, wenn der aufwärts bewegte Kolben 9 kurz vor seiner Endstellung die Schaltstange 2 hochdrückt, so daß nunmehr dieser Schalter die Offenstellung durch entsprechende Signale anzeigt.When the opening process is initiated, the piston 9 moves upwards, the switching cam 5 is brought into the middle by its springs 7 and 8 , whereby the contact of the end position goes back and the display symbols disappear or go out. The 'switch 6a is only actuated when the upwardly moving piston 9 pushes up the switching rod 2 shortly before its end position, so that this switch now indicates the open position by means of corresponding signals.
