Abstract
Description
Die Erfindung betrifft ein Düsenrückschlagventil für den Einsatz in gas- und/oder flüssigkeitsführenden Rohrleitungen mit einem rotationssymmetrischen Gehäuse, einem darin zentrisch angeordneten rotationssymmetrischen Gehäuseeinsatz und einem zwischen dem Gehäuse und dem Gehäuseeinsatz durch Rippen unterteilten, einen Strömungskanal bildenden Ringraum, der durch einen unter Federdruck gegen die Strömungsrichtung eines Durchflussmediums koaxial aus dem Gehäuseeinsatz herausführbaren und gegen einen auf der Innenseite des Gehäuses angeordneten Ventilsitzring anpressbaren Ventilteller absperrbar ist, wobei der Ventilteller mit einer Führungsstange fest verbunden ist, die im Gehäuseeinsatz koaxial und axial verschiebbar gelagert ist. Eine weitere Ausführung besteht aus einem ringförmigen Dichtkolben mit mehreren Führungen.The The invention relates to a nozzle check valve for the Use in gas and / or liquid-carrying Pipelines with a rotationally symmetrical housing, a Centrally arranged rotationally symmetrical housing insert and one between the housing and the housing insert Ribs divided, a flow channel forming annular space by a spring pressure against the flow direction a flow medium coaxially herausführbaren from the housing insert and against a valve seat ring disposed on the inside of the housing can be shut off pressureable valve plate, wherein the valve plate with a guide rod firmly connected in the housing insert is mounted coaxially and axially displaceable. Another version exists from an annular Sealing piston with several guides.
Derartige
Rückschlagventile
sind seit langem bekannt und werden zum Beispiel von der Inhaberin
der
Düsenrückschlagventile der genannten Bauart sind im allgemeinen Pumpen nachgeschaltet. Arbeitet die Pumpe und erzeugt einen entsprechenden Strömungsdruck, so wird das Ventil hierdurch automatisch geöffnet: Steht die Pumpe still, so schließt das Ventil automatisch – aufgrund der auf den Ventilteller wirkenden Feder. Es kann vorkommen, dass das Ventil bei abgeschalteter Pumpe ganz oder teilweise in seiner Offenstellung bleibt. Das Ventil erfüllt dann nicht mehr seine Funktion als Rückschlagventil. Dies kann dazu führen, dass das Ventil von Medium durchströmt wird, und zwar in Richtung auf die Pumpe. Dies kann zu Schäden an der Pumpe, am Motor, der die Pumpe antreibt oder an der Anlage führen.Nozzle check valves said type are generally downstream of pumps. Works the pump and generates a corresponding flow pressure, this will automatically open the valve: if the pump stops, that concludes Valve automatically - due the spring acting on the valve disk. It may happen that Valve with the pump switched off completely or partially in its open position remains. The valve then fulfills no longer its function as a check valve. This can lead to, that the valve is flowed through by medium, in the direction on the pump. This can cause damage on the pump, on the motor that drives the pump or on the system to lead.
Die genannten Erscheinungen können auf mechanische Mängel des Ventils zurückgehen, beispielsweise auf Korrosion, aber auch auf Ablagerungen von Partikeln, die das Medium mitführt.The mentioned phenomena can on mechanical defects going back of the valve, for example, on corrosion, but also on deposits of particles, which carries the medium.
In jedem Falle ist es für den Betreiber wichtig, die aktuelle Stellung des Ventiltellers zu erkennen. Dies ist bisher nicht möglich.In in any case it is for the operator important to the current position of the valve disk detect. This is not possible so far.
Der Erfindung liegt somit die Aufgabe zugrunde, ein Düsenrückschlagventil der beschriebenen Bauart derart zu gestalten, dass die Position seines Ventiltellers zu jedem Zeitpunkt von außen her zuverlässig erkennbar ist.Of the Invention is therefore the object of a nozzle check valve to design the described type such that the position its valve disc at any time from the outside reliably recognizable is.
Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst. Wichtigstes Element der Erfindung ist einbiegsamer Stab, zum Beispiel eine sogenannte Wurmfeder. Der Stab ist mit seinem ersten Ende an den Ventilteller angeschlossen, am besten an dessen Rückseite, d. h. an jener Seite, die nicht von Medium angeströmt ist. Das andere Ende (zweites Ende) ist durch die Wandung des Gehäuses aus dem Ventil herausgeführt. Dies bedeutet, dass der biegsame Stab zwischen seinem ersten und seinem zweiten Ende umgelenkt wird. Hierzu ist eine Führung vorgesehen, beispielsweise eine Hülse, in welcher der Stab gleiten kann. Das genannte zweite Ende, das aus dem Ventil herausgeführt ist, taucht in eine Kammer ein, beispielsweise in eine am einen Ende geschlossene Hülse. Die Kammer steht mit dem Medium im Ventil in leitender Verbindung und dem gemäß auch unter dem Druck des Mediums. Gegen außen hin ist die Kammer hermetisch abgedichtet.These The object is solved by the features of claim 1. The most important Element of the invention is a flexible rod, for example a so-called Garter spring. The rod is with its first end to the valve plate connected, preferably at the back, d. H. on that side, which was not flown by medium is. The other end (second end) is through the wall of the housing from the Led out the valve. This means that the flexible rod between its first and its second end is redirected. For this purpose, a guide is provided, for example, a sleeve, in which the bar can slide. The said second end, the led out of the valve is immersed in a chamber, for example in one at one end closed sleeve. The chamber is in fluid communication with the medium in the valve and according to also below the pressure of the medium. Against the outside The chamber is hermetically sealed.
Der biegsame Stab kann beispielsweise eine sogenannte Wurmfeder sein. Dies ist eine eng gewickelte Schraubenfeder ohne Abstand zwischen den Wicklungen.Of the For example, a flexible rod can be a so-called worm spring. This is a tightly wound coil spring with no gap between the windings.
Die Erfindung ist anhand der Zeichnung näher erläutert. Darin ist im einzelnen folgendes dargestellt:The The invention is explained in more detail with reference to the drawing. This is in detail the following is shown:
