Diese Aufgabe ist erfindungsgemäss mit der Lehre gemäss dem kennzeichnenden Teil der Ansprüche 1 und 7 gelöst.This task is according to the invention with the teaching according to the characterizing part of claims 1 and 7 solved.
Ausführungsformen dieser Lehre sind in den weiteren abhängigen Ansprüchen umschrieben.Embodiments of this teaching are dependent in the further Claims circumscribed.
Die Erfindung ist in der beiliegenden schematischen Zeichnung beispielsweise dargestellt und nachfolgend beschrieben.The invention is illustrated by way of example in the accompanying schematic drawing and below described.
In der Zeichnung ist eine Zufuhrleitung 1 gezeigt, die mit dem Wassernetz verbunden ist. Die Zufuhrleitung 1 ist mit einer zu spülenden Rohrleitung 2 verbunden, wobei zwischen die beiden Leitungen für den Spülvorgang eine Spülvorrichtung 3 eingesetzt wird. Die Spülvorrichtung 3 weist ein Absperrventil 4, ein Rückschlagventil 5, eine Zuleitung 6 für Luft, einen Steuerblock und eine als handelsübliche Pressluft-Flasche ausgebildete Druckluft-Quelle 8 auf. Der Steuerblock 7 weist ein in der Zuleitung 6 angeordnetes Auf-Zu-Ventil 9 auf, welches durch eine pneumatische Servo-Steuerung 10 periodisch in einstellbaren Zeitintervallen über eine Steuer-Leitung 15 betätigt wird. Die Servo-Steuerung weist ein 5/2-Wege-Pneumatikventil 11 auf, welches wiederum mit zwei 3/2-Wege-Pneumatikventilen 12a und 12b durch die Steuer-Leitungen 13a, 13b und 14a, 14b wirkverbunden ist. Die drei Ventile 11, 12a und 12b werden von der Druckluft-Quelle 8 durchIn the drawing, a supply line 1 is shown, which is connected to the water network. The supply line 1 is connected to a pipeline 2 to be flushed, a rinsing device 3 is used between the two lines for the rinsing process. The flushing device 3 has a shut-off valve 4, a check valve 5, a supply line 6 for air, and a control block and a compressed air source 8 designed as a commercially available compressed air bottle. The control block 7 has a in the Supply line 6 arranged on-off valve 9, which is periodically controlled by a pneumatic servo control 10 is actuated in adjustable time intervals via a control line 15. The servo control has a 5/2-way pneumatic valve 11, which in turn has two 3/2-way pneumatic valves 12a and 12b through the control lines 13a, 13b and 14a, 14b is operatively connected. The three valves 11, 12a and 12b are from the compressed air source 8 through
die Leitungen 16 bzw. 16a, 16b und 16c mit Druckluft beaufschlagt. In den Steuer-Leitungen 13a und 13b ist je eine einstellbare Drossel 17a bzw. 17b und ein, ein bestimmtes Volumen aufweisender Behälter 18a bzw. 18b angeordnet. Durch die einstellbaren Drosseln 17a bzw. 17b und das aufzufüllende Volumen wird eine zeitlich verzögerte Schaltung der Ventile 12a und 12b erreicht, durch welche wiederum eine wechselnde periodische, zeitlich einstellbare Umschaltung des Ventils 11 erfolgt. Durch die Schaltungen des Ventils 11 wird die Zufuhr der Steuer-Luft über die Steuer-Leitung 15 zum Auf-ZuVentil 9 abwechselnd geöffnet und geschlossen, durch welches wiederum die Luftzufuhr durch die Zuleitung in die zu reinigende Rohrleitung 2 periodisch gesteuert wird.compressed air is applied to lines 16 or 16a, 16b and 16c. In each of the control lines 13a and 13b there is an adjustable throttle 17a or 17b and one, one Arranged having a certain volume container 18a or 18b. The adjustable throttles 17a resp. 17b and the volume to be filled is achieved a time-delayed switching of the valves 12a and 12b, by which, in turn, an alternating periodic, time-adjustable switchover of the valve 11 takes place. The switching of the valve 11 causes the supply of the control air via the control line 15 to the open-close valve 9 alternately opened and closed, through which in turn the air supply through the supply line is controlled periodically in the pipe 2 to be cleaned.
Anstelle der Behälter 18a und 18b können auch Schlauchoder Rohrleitungen mit einem entsprechend erforderlichen Volumen verwendet werden.Instead of the container 18a and 18b, hose or pipelines with a correspondingly required Volume can be used.
Die zeitliche Verzögerung der Schaltung der Ventile 12a und 12b hängt von der Grosse des Volumens im Behälter 18a bzw. 18b und dem eingestellten Drosselquerschnitt ab und kann durch Verstellung des Drosselquerschnittes in einem gewissen Bereich verändert werden. Vorzugsweise wird diese rein pneumatisch arbeitende und von elektrischem Strom unabhängige Zeitsteuerung so eingestellt, dass Luft-Druckstösse von 3 bis 10 Sek. Dauer nach jeweils Pausen von 3 bis 10 Sek. Dauer in die Rohrleitung 2 eingeleitet werden. Der Druck wird mittels eines Druckreduzier-Ventils 19 in der Leitung 6 auf ca. 8 bis 10 bar eingestellt. Es hat sich gezeigt, dass durch eine derartige pulsierende DruckluftzuführungThe time delay in switching the valves 12a and 12b depends on the size of the volume in the container 18a or 18b and the set throttle cross-section and can be adjusted by adjusting the throttle cross-section can be changed in a certain area. This is preferably purely pneumatic and time control that is independent of electrical power is set in such a way that air pressure surges of 3 to 10 seconds. Duration after pauses of 3 to 10 seconds duration are introduced into the pipe 2. The pressure will adjusted by means of a pressure reducing valve 19 in the line 6 to about 8 to 10 bar. It has shown, that by such a pulsating compressed air supply
in die Spülflüssigkeit eine gute Reinigungswirkung erreicht wird. Zusätzlich kann auch die Zufuhr der Spülflüssigkeit durch abwechslungsweises Oeffnen und Schliessen des Absperrventils 4 mit periodischen Druckstössen erfolgen. Dies kann entweder von Hand mittels eines am Absperrventil 4 angeordneten Handhebels 20 oder automatisch durch die pneumatische Servo-Steuerung 10 erfolgen. Dafür muss, wie in der Fig. strichpunktiert dargestellt, ein pneumatisch betätigbares Absperrventil 4 verwendet werden, welches mit der Steuer-Leitung 15 wirkverbunden ist. Die Druckstösse der Spülflüssigkeit können gleichzeitig oder abwechselnd mit den Druckstössen der Druckluft erfolgen. A good cleaning effect is achieved in the rinsing liquid will. In addition, the rinsing liquid can also be supplied by alternately opening and closing of the shut-off valve 4 take place with periodic pressure surges. This can either be done manually using an am Shut-off valve 4 arranged hand lever 20 or take place automatically by the pneumatic servo control 10. Therefore a pneumatically operated shut-off valve 4 must be used, as shown in dash-dotted lines in the figure, which is operatively connected to the control line 15. The pressure surges of the flushing liquid can be simultaneous or alternate with the pressure surges of the compressed air.
Durch die Spülung mit Wasser aus dem vorhandenen Wassernetz zusätzlich mit Luft-Druckstössen aus einer leicht transportierbaren Pressluft-Flasche wird ein sehr guter Reinigungseffekt mit einfachen Mitteln erreicht. Die einfach zwischen die Rohrleitung einsetzbare Spülvorrichtung mit dem, die Ventile aufweisenden Steuerblock; braucht dann nur mit der Pressluft-Flasche verbunden werden. Die Spülflüssigkeit wird zusammen mit den abgelösten Verunreinigungen am Ende der zu spülenden Rohrleitung in einem Behälter 21 aufgefangen.By flushing with water from the existing water network, additionally with air pressure surges from an easy transportable compressed air bottle, a very good cleaning effect is achieved with simple means. the flushing device that can be easily inserted between the pipeline and has the control block with the valves; then only needs to be connected to the compressed air cylinder. The rinsing liquid is used together with the Detached contaminants at the end of the pipeline to be flushed are collected in a container 21.
