Description

Ablaßventil für Förderrohrleitungen von Senkpumpen Bei den mit der Förderrohrleitung in das Bohrloch herabgelassenen Senkpumpen bleibt nach Stillsetzen der Pumpe die Förderrohrleitung bis oben hin mit Flüssigkeit gefüllt, so daß bei den zum Ausbauen der Pumpe erfolgten Lockern der Verbindungsstelle der einzelnen Rohrschüsse die in dem betreffenden Rohrschuß befindliche Flüssigkeit an der Verbindungsstelle ausströmt und das Arbeiten erheblich erschwert.Drain valve for delivery pipes of lowering pumps For those with the Production pipeline lowered into the borehole remains after shutdown the pump filled the delivery pipeline with liquid up to the top, so that at the loosening of the connection point between the individual pumps that was carried out to remove the pump Pipe sections the liquid located in the pipe section in question at the connection point flows out and makes work considerably more difficult.

Die Erfindung betrifft nun ein Ablaßventil, das in das untere Ende der Förderrohrleitung eingebaut wird und vor dem Ausbauen der Senkpumpe geöffnet wird, wodurch die in der Rohrleitung befindliche Flüssigkeit abfließen kann. Das gemäß der Erfindung ausgebildete Ablaßventil besteht aus einer Membran oder Scheibe, die normalerweise die Ablaßöffnung verschließt und beim Überschreiten des normalen Förderdruckes zersprengt wird und hierdurch die Ablaßöffnungen freigibt. Den zum Öffnen des Ventils erforderlichen Druck kann man über Tage durch Abdrosseln der geförderten Flüssigkeit erzeugen. Man kann zu diesem Zweck aber auch von über Tage aus mittels einer kleinen Pumpe die in der Förderrohrleitung enthaltene Flüssigkeit unter höheren Druck setzen.The invention now relates to a drain valve which is in the lower end the delivery pipe is installed and opened before removing the lowering pump which allows the liquid in the pipeline to flow away. That according to the invention designed drain valve consists of a membrane or disc, which normally closes the drain opening and when exceeding the normal Delivery pressure is burst and thereby releases the drainage openings. The for Opening the valve required can be done by throttling off the pressure for days Generate pumped liquid. For this purpose, however, you can also use it from above ground from the liquid contained in the delivery pipe by means of a small pump put under higher pressure.

In der Abbildung ist ein Ausführungsbeispiel der Erfindung im Längsschnitt dargestellt. Die beiden Rohrschüsse ii der Förderleitung sind durch eine Muffe 12 miteinander verbunden, die mit einer Bohrung 13 versehen ist. In diese Bohrung ist ein Rohrnippel 1q. eingeschraubt,. an dessen anderem Ende eine beispielsweise aus dünnem Messingblech bestehende Membran 15 durch die mit der Öffnung 17 versehene Überwurfmutter 16 befestigt ist. Die Membran 15 widersteht dem normalen Förderdruck, wird aber bei Überschreiten des Druckes zersprengt und gibt die Ablaßöffnung 17 frei.In the figure is an embodiment of the invention in longitudinal section shown. The two pipe sections ii of the delivery line are connected by a sleeve 12 connected to one another, which is provided with a bore 13. In this hole is a pipe nipple 1q. screwed in. at the other end, for example, one off thin brass sheet existing membrane 15 through the provided with the opening 17 Union nut 16 is attached. The membrane 15 withstands the normal delivery pressure, but is burst when the pressure is exceeded and opens the drain opening 17 free.

Die Erfindung hat den Vorteil eines äußerst einfachen Aufbaues und verengt den Förderquerschnitt der Rohrleitung ii nicht, so daß der Widerstand der Rohrleitung ii für die Förderflüssigkeit in keiner Weise vergrößert wird.The invention has the advantage of an extremely simple structure and does not narrow the delivery cross-section of the pipeline ii, so that the resistance of the Pipeline ii for the delivery liquid is in no way enlarged.
