Das Ventil wird durch den Druck des von der Pumpe geförderten, abfließenden Wassers geöffnet und durch, den Wasserrückfluß beim Aussetzen der Purapenwirkung selbsttätig geschlossen. Es kommt jedoch vor, daß der Eüekflußstroto eine höhere Geschwindigkeit annimmt, wobei die Geschwindigkeit selbst und der Druck der Masse des zurück·» fließenden Wassers das schlagartige Schließen des Klappenventils verursachen, so daß heftige Druckstöße in dem Teil vor dem Ventil unvermeidlich auftreten, die bekannte Störungen an den leitungen, besonders bei häufiger Wiederholung, bewirken·The most common type of valve used in well heads is the flap valve. The valve is activated by the pressure of the The outflowing water conveyed by the pump is opened and through, the water reflux when the Purapen effect is suspended closed automatically. However, it happens that the Eüekflussstroto assumes a higher speed, the speed itself and the pressure of the mass of the back · » flowing water cause the sudden closing of the flap valve, so that violent pressure surges in the part inevitably occur in front of the valve, the known faults on the lines, especially with frequent repetition, cause·

Das Rohrstück 4 ist mit einem Flnasch 4a für die Verbindung des Brunnenkopfes mit dem passenden, am Steigleitungsrohr befindlichen Flansch versehen.The pipe section 4 is with a Flnasch 4a for the connection of the well head with the appropriate one on the riser pipe provided flange.
Die Wirkungsweise des erfindungsgemäßen Brunnenkopfes ist folgende:The mode of action of the well head according to the invention is as follows:
Das durch die Tauchpumpe in die Kammer B des Trichters 8 geförderte Wasser verursacht mit seinem Druck das Anheben des Tellers 18 und fließt durch die Öffnungen 17 in den Hohlraum des Rohrstückes 4 und von hier durch den Abflußstutzen C desselben In die Steigleitung. In dem Augenblick, wo der die 'fauchpumpe antreibende Elektromotor ausgeschaltet wird, fällt plötzlich 4er Druck des von der Pumpe geförderten Wassers in der Kammer B ab und hört ganz auf. Der Teller 18, der im Betrieb durch das von der Pumpe geförderte Wasser angehoben wird, wird jetzt nicht mehr von dem Wasser abgestützt und fällt durch Schwerkraft ab, wobei der Teller die Drucköffnungen 17 schlagartig schließt und ein Zurückfließen des im Raum A vorhandenen bzw. irgendwie aus der am Abflußstutzen C angeschlossenen Steigleitung kommendenThe pressure of the water pumped into the chamber B of the funnel 8 by the submersible pump causes it to rise of the plate 18 and flows through the openings 17 into the cavity of the pipe section 4 and from here through the drainage connection C of the same in the riser. At the moment when the electric motor that drives the hissing pump is switched off the pressure of the water delivered by the pump in chamber B suddenly drops and stops completely. Of the Plate 18, which is raised during operation by the water delivered by the pump, is no longer used by the water supported and falls off by gravity, the plate closing the pressure openings 17 suddenly and a backflow of the existing in room A or somehow coming from the riser connected to the drain connector C.
209827/0567209827/0567
Wassers verhindert. In diesem Zustand wird infolge des augenblicklichen Schließens des aus den Öffnungen 17 und dem Teller 18 bestehenden Yentils das Zurückfließen des Wassers und somit auch jede Möglichkeit eines Druckstoßes in den angeschlossenen Leitungen verhindert.Water prevented. In this state, as a result of the instantaneous closing of the valve consisting of the openings 17 and the plate 18, the backflow of the water and this also prevents any possibility of a pressure surge in the connected lines.
Aus dem oben Gesagten geht die einfache, zuverlässige Funktion des im erfindungsgemäßen Brunnenkopf eingebauten Tentils klar hervor, das durch das Eigengewicht des Tellers 1Θ die öffnungen 17 schließt, sobald der Druck des durch die Pumpe geförderten Wassers aufhört, und diese erst dann wieder öffnet, wenn der Wasserdruck wieder auf einen bestimmten Wert steigt.From what has been said above, the simple, reliable function of the valve built into the well head according to the invention is clear out that by the weight of the plate 1Θ the openings 17 closes as soon as the pressure of the water delivered by the pump ceases, and it only opens again when the Water pressure rises again to a certain value.
Insbesondere verringert sich der ringförmige Zwischenraum für das Durchströmen des Wassers zwischen Teller 18 und Flansch 9 mit dem Abnehmen der Strömungsgeschwindigkeit des Wassers und schließt sich ganz, wenn diese Geschwindigkeit gleich Null wird, und zwar bevor die Geschwindigkeit $©s Wasserrückflueses irgendeinen, sei es auch nur kleinsten Wert annimmt. In dem Augenblick, in dem sich ä@T Zustand einstellt, der ein Zurückfließen des Wassers erläutern w&?de, 1st das Ventil bereits ganz geschlossen, so daß das Eintreten eines Druckstoßes unmöglich gemacht wird.In particular, the annular space for the water to flow through between the plate 18 and the flange 9 decreases with the decrease in the flow velocity of the water and closes completely when this velocity equals zero, before the velocity of the water reflux either, be it only takes on the smallest value. In the moment in which ä @ T state is reached, the w explain a backflow of water & de, the valve 1st already completely closed, so that the occurrence of a pressure surge is impossible.
