Description

Überstromventil, insbesondere Sicherheitsventil Die Erfindung bezieht sich auf ein überstromventil, insbesondere auf ein Sicherheitsventil, welches pneumatisch oder hydraulisch zu betätigen ist.Overflow valve, especially safety valve The invention relates on an overflow valve, in particular on a safety valve, which is pneumatic or is to be operated hydraulically.

Es sind bereits Überdrucksicherheitsventile, insbesondere für Pumpendruckleitungen vorgeschlagen worden, bei denen eine Membran vorgesehen ist, die einerseits vom abzusichemden Druck und andererseits vom Gasdruck beaufschlagt wird.There are already overpressure safety valves, especially for pump pressure lines have been proposed in which a membrane is provided on the one hand from pressure and on the other hand is acted upon by gas pressure.

Durch die Erfindung wird ein überstromventil geschaffen, welches sich durch besonders einfache Bauweise und Betriebssicherheit auszeichnet.The invention provides an overflow valve which characterized by a particularly simple design and operational reliability.

Das überstromventil, insbesondere das Sicherheitsventil gemäß der Erfindung besitzt wie die bekannten Ventile zur Einstellung des Solldruckes eine pneumatisch oder hydraulisch beaufschlagte, als Schließorgan wirkende Membran. Erfindungsgemäß ist der Schließdruck mittels eines pneumatisch oder hydraulisch aufblähbaren Beutels, der an der Membran anliegt, einstellbar.The overflow valve, in particular the safety valve according to the Invention, like the known valves for setting the target pressure, has a pneumatically or hydraulically loaded membrane acting as a closing element. According to the invention is the closing pressure by means of a pneumatically or hydraulically inflatable bag, which rests on the membrane, adjustable.

An Hand der Zeichnung wird die Erfindung näher erläutert. Die Zeichnung zeigt schematisch in einem Ausführungsbeispiel ein überstromventil mit den Merkmalen der Erfindung.The invention is explained in more detail with reference to the drawing. The drawing shows schematically in one embodiment an overflow valve with the features the invention.

Auf einem Glas- oder Keramikventilgehäuse a ist ein halbkugeliges Metallgehäuse b aufgeflanscht. Zwischen die Flansche eingespannt befindet sich eine Membran c aus säureresistentem flexiblem Stoff, beispielsweise aus Polytetrafluofäthylen. Auf dieser Membran c aufliegend befindet sich ein Gummibeutel d innerhalb des Metallgehäuses b. über einen Zuflußstutzen e kann nun Preßluft oder eine Flüssigkeit (öl oder Wasser) in den Gummibeutel gepreßt werden. Die Membran wird dann durch Aufblähen des Gummibeutels fest gegen den überfließstutzen f gepreßt. Das Ventil ist somit geschlossen. A hemispherical metal housing b is flanged onto a glass or ceramic valve housing a. A membrane c made of acid-resistant flexible material, for example made of polytetrafluoroethylene, is clamped between the flanges. A rubber bag d rests on this membrane c inside the metal housing b. Compressed air or a liquid (oil or water) can now be pressed into the rubber bag via an inlet connection e. The membrane is then pressed firmly against the overflow nozzle f by inflating the rubber bag. The valve is thus closed.

Auf dem Gehäuse b befindet sich ferner ein Manometer g, welches den Solldruck innerhalb des Gummibeutels anzeigt. Die Einstellung des überströmdruckes kann mittels des Manometers g kontrolliert werden. Soll sich beispielsweise das Sicherheitsventil erst bei 5 atü öffnen, so muß auch der Vordruck im Gummibeutel 5 atü betragen. Das Ventil läßt sich besonders gut für Ferneinstellung verwenden. In diesem Falle verbindet man den Stutzen e mittels einer Rohrleitung oder eines Schlauches mit dem Bedienungsstand. Das Ventil kann dann aus beliebiger Entfernung mittels Preßluft oder Flüssigkeit probeweise geÖffnet werden. Die Einstellung des auf diese Weise gebauten Sicherheitsventils kann über ein Manometer am Bedienungsstand aus beliebiger Entfernung vorgenommen werden. Der Aufbau des Ventils gemäß dem Ausführungsbeispiel ist derart getroffen, daß alle durch das Ventil strömenden Medien nur mit säureresistenten Werkstoffen, wie Glas und Keramik, in Berührung kommen. Dadurch wird für das Ventil ein großes Anwendungsgebiet erschlossen.On the housing b there is also a manometer g, which shows the target pressure within the rubber bag. The setting of the overflow pressure can be checked using the manometer g. If, for example, the safety valve is to open only at 5 atmospheres, the form in the rubber bag must also be 5 atmospheres. The valve can be used particularly well for remote adjustment. In this case, the nozzle e is connected to the control station by means of a pipe or a hose. The valve can then be opened on a trial basis from any distance using compressed air or liquid. The setting of the safety valve built in this way can be made from any distance using a pressure gauge on the control station. The structure of the valve according to the embodiment is made such that all media flowing through the valve only come into contact with acid-resistant materials such as glass and ceramics. This opens up a large area of application for the valve.
