Description

Kammerwasser- und Schlammheber, dessen Förderkessel unter Vermittelung einer durch Schwimmer bewegten Relaissteuerung abwechselnd mit der Saug- und Druckleitung eines Kompressors in Verbindung gebracht wird. Gemäß dem Hauptpatent soll die Relaissteuerung mit einem Druckspeicher in Verbindung gebracht werden, der während der Druckperiode unter Druck gesetzt wird, um auch während der Saugperiode ein Umsteuern des Hauptorgans ermöglichen zu können. Diese Anordnung erfordert also einen besonderen Druckspeicher, der bei Inbetriebsetzung der Anlage erst auf den notwendigen Druck gebracht werden muß, damit die Relaissteuerung richtig arbeiten kann. Ist dies geschehen, dann arbeitet natürlich die Einrichtung einwandfrei, da der notwendige Druck immer wieder selbsttätig nachgefüllt wird.Aqueous humor and sludge lifter, its conveying tank under mediation a relay control moved by floats alternating with the suction and pressure lines a compressor is associated. According to the main patent, the relay control be associated with a pressure accumulator which is used during the printing period is put under pressure in order to reverse the direction of the main organ even during the suction period to enable. This arrangement therefore requires a special pressure accumulator, which are only brought to the necessary pressure when the system is commissioned must for the relay control to work properly. If this is done, then work Of course, the facility is flawless, as the necessary pressure is always automatic is refilled.

Es hat sich nun bei weiteren Versuchen herausgestellt, daß man unter Umständen den Druckspeicher ganz entbehren kann, und zwar geschieht dies gemäß der Erfindung durch Anordnung eines belasteten Ventils in der Druckleitung zwischen Kompressor und Hauptsteuerorgan in der Art, daß in der Leitung zwischen diesem Ventil und dem Druckstutzen des Kompressors imitier ein bestimmter Mindestdruck herrscht, der Igenügt, uin die Umsteuerung zu bewirken.It has now been found in further experiments that one under Circumstances can dispense with the pressure accumulator entirely, this is done according to the Invention by arranging a loaded valve in the pressure line between Compressor and main control element in the manner that in the line between this valve and the pressure port of the compressor imitates a certain minimum pressure, that is enough to bring about a change of direction.

Abgesehen von dem Vorteil, daß hierbei eiii besonderer Druckspeicher in Wegfall kommt, besitzt dieser Weiterausbau der Erfindung noch den besonderen, daß sofort bei Betriebsbeginn der zum Umsteuern notwendige Druck zur Verfügung steht, da beim Anlassen des Kompressors in dem verhältnismäßig kleinen Raum zwischen Druckstutzen des Kompressors und Ventil sofort der für die Umsteuerung notwendige Druck erzeugt wird. Infolgedessen kann man auch bei Verwendung eines Druckspeichers gemäß dem Hauptpatent den Druckspeicher wesentlich kleiner halten.Apart from the advantage that it has a special pressure accumulator in the absence of this, this further development of the invention still has the special that the pressure required for reversing is available immediately at the start of operation, because when starting the compressor in the relatively small space between the pressure port of the compressor and valve immediately generates the pressure required for the reversal will. As a result, you can also when using a pressure accumulator according to the Main patent keep the pressure accumulator much smaller.

Auf der Zeichnung ist ein Ausführungsbeispiel eines derartigen Ventils in senkrechtem Schnitt dargestellt. An den Druckstutzen i des Kompressors schließt unter Zwischenschaltung eines '['-.Stückes 2 ein Ventil 3 an, dessen andere Seite durch ein Rohr 4 mit dein Hauptsteuerorgan verbunden ist. Der zweite Ast 5 des '['-Stückes 2 führt zur Relaissteuerung.The drawing shows an embodiment of such a valve shown in vertical section. Closes to the pressure port i of the compressor with the interposition of a '[' -.Piece 2, a valve 3, the other side is connected to your main control unit by a pipe 4. The second branch 5 of the '[' piece 2 leads to relay control.

Der mit Doppelsitz ausgestattete Ventilkörper 6 steht mit einem Kolben 7 in Verbin--lung, der in einem iin Ventildeckel 8 vorgesehenen Zylinder arbeitet. Dieser Kolben ist durch ein Gewicht g belastet, das zwecks Einstellung der Belastung auf der Hebelstange io verschiebbar ist.The valve body 6 equipped with a double seat stands with a piston 7, which works in a cylinder provided in valve cover 8. This piston is loaded by a weight g that is used to adjust the load is slidable on the lever rod io.

Sobald der Kompressor in Tätigkeit gesetzt wird, entsteht in dem Rohrstück zwischen Kompressor und Ventil 3 sofort ein Überdruck, da das Ventil unter Einwirkung des Gewichtes g geschlossen ist. Steigt der Druck nach einigen Hüben des Kompressors über ein bestimmtes Maß an, dann wird der Kolben 7 gegen den Druck des Gewichtes g gehoben und mit ihm der Ventilteller 6, so daß nunmehr die Druckluft zum Hauptsteuerorgan gelangt.As soon as the compressor is put into operation, arises in the pipe section an overpressure between the compressor and valve 3 immediately, as the valve is under action of weight g is closed. If the pressure increases after a few strokes of the compressor over a certain amount, then the piston 7 is against the pressure of the weight g lifted and with it the valve disk 6, so that now the compressed air to the main control element got.
