Abstract
Es wird ein Gasventil, insbesondere ein Dosierventil für ein gasförmiges Medium, angegeben, das eine in einem Ventilgehäuse (11) ausgebildete Ventilkammer (12) mit mindestens zwei Kammeröffnungen (13, 14), von denen eine erste Kammeröffnung (13) von einem Ventilsitz (15) ringförmig umschlossen ist, und einen in der Ventilkammer (12) angeordneten Schließkörper (16) aufweist, an dem ein auf den Ventilsitz (15) aufsetzbarer und vom Ventilsitz (15) abhebbarer Dichtsitz (17) ausgebildet ist. Zur Realisierung eines für eine optimale Dosierung des gsförmigen Mediums erforderlichen, druckausgeglichenen Ventils, bei dem der auf die voneinander abgekehrten Stirnseiten des Schließkörpers (16) wirkende Druck bei sich öffnendem Ventil stets gleich ist und somit den Öffnungshub des Schließkörpers (16) nicht beeinflusst, trennt eine am Schließkörper (16) und am Ventilgehäuse (11) festgelegte, flexible Trennwand (28) einen auf der von dem Ventilsitz (15) abgekehrten Rückseite des Schließkörpers (16) liegenden Rückraum (29) von der Ventilkammer (12) gasdicht ab und ist in den Schließkörper (16) mindestens ein den Rückraum (29) mit der ersten Kammeröffnung (13) verbindender Kanal (30) eingebracht.The invention relates to a gas valve, in particular a metering valve for a gaseous medium, which has a valve chamber (12) with at least two chamber openings (13, 14), of which a first chamber opening (13) is formed by a valve seat (11). 15) is annularly surrounded, and in the valve chamber (12) arranged closing body (16), on which a valve seat (15) can be placed and lifted off the valve seat (15) sealing seat (17) is formed. In order to realize a pressure-compensated valve which is required for optimum metering of the gaseous medium and in which the pressure acting on the end faces of the closing body (16) facing away from each other is always the same for the opening valve and thus does not affect the opening stroke of the closing body (16) a on the closing body (16) and the valve housing (11) fixed, flexible partition (28) lying on the back of the valve body (15) rear side of the closing body (16) lying back space (29) from the valve chamber (12) from gas-tight and off at least one channel (30) connecting the rear space (29) with the first chamber opening (13) is introduced into the closing body (16).
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Gasventil, insbesondere einem Dosierventil für ein gasförmiges Medium, nach dem Oberbegriff des Anspruchs 1.The The invention is based on a gas valve, in particular a metering valve for a gaseous medium, according to the generic term of claim 1.
Ein
bekanntes Gasventil zur Dosierung von gasförmigem Brennstoff,
wie Erdgas, Flüssiggas oder Wasserstoff, für Gasmotoren
oder Brennstoffzellenantriebe (
Beim Öffnen des Gasventils entsteht zwischen dem Vordruck auf der Zuströmseite und dem Nachdruck auf der Abströmseite des Ventilsitzes in Verbindung mit der pneumatisch wirksamen Fläche des Dichtelements eine pneumatische Öffnungskraft, die die zum Öffnen des Ventils durch Elektromagnet und Ventilöffnungsfeder bereitgestellte Öffnungskraft stark verändert. Als Folge dessen ist die Größe des Abhebewegs des Dichtelements vom Ventilsitz, also der Ventilhub, stark abhängig von der Größe des Vor- und Nachdrucks und somit die Brennstoffdosierung bei wechselnden Druckverhältnissen nicht ausreichend exakt.When opening the gas valve is created between the inlet pressure on the inflow side and the emphasis on the downstream side of the valve seat in conjunction with the pneumatically effective surface of the Sealing element has a pneumatic opening force, which the to open the valve by solenoid and valve opening spring provided opening force changed greatly. As a result, the size of the Abhebewegs of the sealing element from the valve seat, so the valve lift, highly dependent on the size of the pre- and reprint and thus the fuel dosage at changing pressure conditions not exactly accurate.
Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Gasventil mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass durch die gasdichte Verbindung des Schließkörpers mit dem Ventilgehäuse mittels einer flexiblen Trennwand und durch das Vorsehen eines Verbindungskanals im Schließkörper, der eine Verbindung von dem gemeinsam von der Trennwand und dem Schließkörper abgetrennten Rückraum zur ersten Kammeröffnung herstellt, ein druckausgeglichenes Ventil realisiert wird, bei dem auf beiden Seiten des Schließkörpers der gleiche Gasdruck herrscht, Vor- und Nachdruck am Schließkörper also identisch sind. Dadurch, dass auch die Trennwand am Schließkörper so festgelegt ist, dass ein den Rückraum begrenzender Oberflächenabschnitt auf der einen Seite des Schließkörpers annähernd gleich groß ist wie der von dem Dichtsitz eingegrenzte Oberflächenabschnitt auf der dem Ventilsitz zugekehrten anderen Seite des Schließkörpers, sind die auf die mit dem gleichen Druck beaufschlagten, voneinander abgekehrten Stirnflächen des Schließkörpers in Öffnungs- und Schließrichtung wirkenden Axialkräfte gleich groß und heben sich gegenseitig in ihrer Wirkung auf den Schließkörper auf. Damit ist der Ventilhub beim Öffnen des Ventils unabhängig von den in der Ventilkammer herrschenden Druckverhältnissen und die Brennstoffdosierung kann hochgenau ausschließlich durch Bemessen einer am Schließkörper angreifenden, z. B. elektromagnetisch oder piezoelektrisch erzeugten Hubkraft vorgenommen werden.The Gas valve according to the invention with the features of Claim 1 has the advantage that by the gas-tight connection the closing body with the valve housing by means of a flexible partition and by the provision of a connection channel in the closing body, a joint of the common separated from the partition and the closing body Rear room to the first chamber opening manufactures, a pressure balanced valve is realized, on both sides the closing body of the same gas pressure prevails, Pre- and final pressure on the closing body so identical are. As a result, also the partition on the closing body is set so that the rear space limiting surface portion approximately on one side of the closing body the same size as the one bounded by the sealing seat Surface section on the valve seat facing other side of the closing body, those are on the applied with the same pressure, facing away from each other end faces of the closing body in the opening and closing direction acting axial forces the same size and stand out each other in their effect on the closing body on. Thus, the valve lift when opening the valve is independent from the prevailing pressure in the valve chamber and the fuel metering can be highly accurate exclusively by Measuring a closing body attacking, z. B. electromagnetically or piezoelectrically generated lifting force be made.
Durch die in den weiteren Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Anspruch 1 angegebenen Gasventils möglich.By the measures listed in the further claims are advantageous developments and improvements of the claim 1 specified gas valve possible.
Die flexible Trennwand kann gemäß vorteilhaften Ausführungsformen der Erfindung auf unterschiedliche Weise realisiert werden, z. B. durch eine am Schließkörper und an der Ventilkammer befestigte Membran oder einen am Schließkörper und am Ventilgehäuse festgelegten Faltenbalg oder einen glattwandigen, ein- oder ausbeulbaren Hohlzylinder, dessen eines Stirnende am Schließkörper und dessen anderes Stirnende an der Kammerwand der Ventilkammer befestigt ist, oder durch eine steifen Hohlzylinder, der mit einem Zylinderende am Schließkörper befestigt und mit seinem davon abgekehrten, anderen Zylinderende im Ven tilgehäuse gleitverschieblich und gasdicht aufgenommen ist. Die Trennwand kann aus Metall oder Kunststoff bestehen.The flexible partition may according to advantageous embodiments the invention can be realized in different ways, for. B. by a on the closing body and on the valve chamber attached membrane or one on the closing body and on the valve housing fixed bellows or a smooth-walled, one or dentable hollow cylinder whose one end face on the closing body and its other front end on the chamber wall of the valve chamber is fastened, or by a stiff hollow cylinder, which with a Cylinder end attached to the closing body and with his turned away from it, other cylinder end in Ven tilgehäuse slidable and gas-tight is added. The partition can made of metal or plastic.
