Description
Hilfsgesteuertes Absperr- oder Steuerventil mit einem Hilfsdruckraum Zusatz zur Anmeldung: H 34578 XII / 47 g -Auslegeschrift 1075 392 Die Erfindung betrifft ein Absperr- oder Steuerventil mit Auslösung durch ein vorzugsweise magnetisch betätigtes Hilfsventil, das mittels Hilfsleitungen den Druckauf- und -abbau in einem Druckraum über einen Servokolben steuert, wobei dem Druckraum ein zusätzlicher Hilfsdruckraum zugeordnet ist, nach Patentanmeldung H 34578 XII / 47 g (deutsche Auslegeschrift 1075 392).Pilot operated shut-off or control valve with an auxiliary pressure chamber Addition to registration: H 34578 XII / 47 g -Auslegeschrift 1075 392 The invention relates to a shut-off or control valve with triggering by a preferably magnetic Actuated auxiliary valve that uses auxiliary lines to build up and reduce pressure in one Controls the pressure chamber via a servo piston, the pressure chamber being an additional auxiliary pressure chamber is assigned, according to patent application H 34578 XII / 47 g (German Auslegeschrift 1075 392).
Die Erfindung hat zur Aufgabe, den Hilfsdruckraum nach einem vorbestimmten Gesetz wahlweise wirksam werden zu lassen oder stillzulegen, um den Anwendungsbereich des Ventils zu erweitern.The invention has for its object, the auxiliary pressure chamber after a predetermined Act either to take effect or to shut down to the scope of the valve to expand.
Nach der Erfindung wird dies dadurch erreicht, daß der Hilfsdruckraum über ein wahlweise ein- und ausschaltbares Ventil an die Hilfsleitung für die Druckmittelzuführung zum Druckraum angeschlossen ist.According to the invention, this is achieved in that the auxiliary pressure chamber Via a valve that can be optionally switched on and off to the auxiliary line for the pressure medium supply is connected to the pressure chamber.
Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further features of the invention emerge from the subclaims.
Wie im einzelnen die Erfindung ausführbar ist, zeigt das Ausführungsbeispiel in der Zeichnung in F i g. 1 und 2 in zwei verschiedenen Stellungen.The exemplary embodiment shows how the invention can be carried out in detail in the drawing in FIG. 1 and 2 in two different positions.
In dem Ventilgehäuse 1 befinden sich das Doppelverschlußstück 2 des Mehrwegeventils und der Servokolben 3 für den Antrieb der Verschlußstücke 2 in dem Druckraum 4. Vom Zulauf 5 dieses Ventils ist eine Hilfsleitung 6 abgezweigt, die zu dem vorzugsweise als Dreiwegeventil ausgebildeten Hilfsventil?, und zwar dem unteren Ventilsitz 8, während der Anschluß 9 in den Rücklauf oder ins Freie geführt ist.In the valve housing 1 are the double locking piece 2 of the Multi-way valve and the servo piston 3 for driving the locking pieces 2 in the Pressure chamber 4. An auxiliary line 6 is branched off from the inlet 5 of this valve, which to the auxiliary valve, which is preferably designed as a three-way valve? lower valve seat 8, while connection 9 is routed into the return or into the open is.
Der dritte Abgang 10 führt zum Druckraum 4 mittels der Leitung 11. An diese Leitung 11 ist eine weitere Leitung 12 angeschlossen, die zu einem Ventil 13 führt, welches vorzugsweise als mittels eines Magneten 14 auslösendes Durchgangsventil ausgebildet ist, dessen Abgang 15 in den Hilfsdruckraum 16 mündet.The third outlet 10 leads to the pressure chamber 4 by means of the line 11. A further line 12 is connected to this line 11 , which leads to a valve 13, which is preferably designed as a straight-way valve triggered by means of a magnet 14, the outlet 15 of which into the auxiliary pressure chamber 16 flows out.
Ist das Ventil 13 nach F i g. 1 geschlossen, dabei das Hilfsventil 7 geöffnet und der Rücklauf 9 dadurch geschlossen, dann wird in den Druckraum 4 ungedrosselt ein Druckaufbau erzeugt, der zur beschleunigten Umstellung des Verschlußstücks 2 führt. Wird das Hilfsventil ? nach Abschaltung mittels der Feder 17 in die dargestellte Stellung zurückgeführt, dann erfolgt auch beschleunigter Druckabbau vor den Servokolben 3 in den Rücklauf 9.If the valve 13 is shown in FIG. 1 closed, while the auxiliary valve 7 is opened and the return line 9 is closed as a result, a pressure build-up is then generated in the pressure chamber 4, unthrottled, which leads to the accelerated changeover of the closure piece 2. Will the auxiliary valve? returned to the position shown after switching off by means of the spring 17, an accelerated pressure reduction then also takes place in front of the servo piston 3 in the return line 9.
Wird aber bei Einschaltung des Hilfsventils 7 nach F i g. 2 gleichzeitig auch das Ventil 13 geöffnet, dann erfolgt der Druckaufbau in dem Raum 4 zeitlich verzögert entsprechend der Füllmenge des Hilfsdruckraums 16. Wird bei geöffnetem Ventil 13 jetzt auch das Hilfsventil 7 wieder nach F i g. 1 auf den unteren Sitz 8 bewegt und dieser geschlossen, dann erfolgt auch ein verzögerter Druckabbau vor dem Servokolben 3 in den Rücklauf 9 entsprechend dem größeren Füllvolumen des zugeschalteten Hilfsdruckraums 16 und gegebenenfalls einer in der Leitung 15 vorgesehenen Drosselstelle 18.But if the auxiliary valve 7 is switched on according to FIG. 2, the valve 13 is also opened at the same time, then the pressure build-up in the space 4 takes place with a time delay according to the filling quantity of the auxiliary pressure chamber 16. If the auxiliary valve 7 is now also shown again according to FIG. 1 moves to the lower seat 8 and this is closed, then there is also a delayed pressure reduction in front of the servo piston 3 in the return line 9 corresponding to the larger filling volume of the connected auxiliary pressure chamber 16 and possibly a throttle point 18 provided in the line 15.
Es sind noch zwei weitere Anwendungsbereiche denkbar, und zwar wenn das Hilfsventil 7 nach F i g. 2 umgeschaltet wird, während das Ventil 13 jedoch geschlossen bleibt. Damit erfolgt ein beschleunigter Druckaufbau vor dem Kolben 3. Wenn jetzt das Hilfsventil 7 wieder nach F i g. 1 umgeschaltet, aber gleichzeitig das Ventil 13 geöffnet wird, kann je nach der Größe der Drosselstelle 18 ein entsprechend verzögerter Druckabbau erfolgen. Auch ein erst verzögerter und dann anschließend beschleunigter Druckabbau sowie die umgekehrte Arbeitsweise ist denkbar.There are two other areas of application conceivable, namely if the auxiliary valve 7 according to FIG. 2 is switched, while the valve 13, however remains closed. This results in an accelerated build-up of pressure in front of the piston 3. If now the auxiliary valve 7 is back to FIG. 1 switched, but at the same time the valve 13 is opened, depending on the size of the throttle point 18, a correspondingly delayed pressure reduction take place. Also a delayed one and then afterwards Accelerated pressure reduction and the reverse mode of operation are conceivable.
