Description

DEUTSCHESGERMAN

Die vorliegend beschriebene Erfindung betrifft ein hilfsgesteuertes Membranventil, das gegen die Strömungsrichtung schließt und in der Schließbewegung durch eine zusätzliche Drosselung des auf die Rückseite der Membran führenden Kanals gebremst wird.The presently described invention relates to an auxiliary-controlled diaphragm valve that operates against the direction of flow closes and in the closing movement by an additional throttling of the on the back the membrane leading channel is braked.

Es sind solche Ventile bekannt, die aber mit einem Kolben arbeiten, der eine den Zuflußraum mit dem Raum über dem Kolben verbindende Bohrung aufweist. Durch einen in diese Bohrung hineinragenden Stift, der sich an der Innenseite des Gehäuses abstützt, kann je nach Wahl des Durchmessers des Stiftes bzw. der Größe der Bohrung der Zulauf zur Rückseite des Kolbens und damit die Öffnungs- und Schließgeschwindigkeit geändert werden.There are such valves known, but they work with a piston, the one with the inflow chamber Has space above the piston connecting bore. Through a protruding into this hole The pin, which is supported on the inside of the housing, can, depending on the choice of the diameter of the pin or the size of the bore of the inlet to the back of the piston and thus the opening and closing speed be changed.

Ein ähnliches Ventil sieht einen in die zum Abtlußraum führende Bohrung hineinragenden verstellbaren konischen Stift vor, durch welchen die Bewegungen des Ventils entsprechend der Ausbildung und Einstellung des Stiftes verändert werden kann.A similar valve looks into the drainage room leading bore protruding adjustable conical pin through which the movements of the valve can be changed according to the design and setting of the pin.

Erfindungsgemäß besitzt die Membran einen in den Zuflußraum hineinragenden, zusammendrückbaren Ansatz, der für den Zulauf des Druckmittels auf die Rückseite der Membran mit einer gedrosselten Bohrung versehen ist, welche beim Aufsetzen auf den Boden des Ventilgehäuses verschlossen wird. Dadurch wird eine zusätzliche Bremsung des Schließvorganges erreicht.According to the invention, the membrane has a compressible one which projects into the inflow space Approach for the inlet of the pressure medium to the back of the membrane with a throttled bore is provided, which is closed when placed on the bottom of the valve housing. Through this an additional braking of the closing process is achieved.

Weitere Merkmale der Erfindung sind in der nachfolgenden Beschreibung und Zeichnung sowie in den Ansprüchen enthalten.Further features of the invention can be found in the following description and drawing as well as in FIGS Claims included.

Fig. 1 zeigt das Ventil in geschlossenem Zustand.Fig. 1 shows the valve in the closed state.

Das Ventil wird gebildet von dem Gehäuseunterteil 1, dem Oberteil 2 mit Führungsrohr 3, der Magnetspule 4, dem Magnetanker 5 und der Membran 6. welche durch ein eingebettetes Metallteil an der Sitzfläche verstärkt werden kann. Die Membran 6 besitzt einen in den Zuflußraum hineinragenden zusammendrückbaren Ansatz 7, der mit einer den Zuflußraum des Ventils mit dem Raum über der Membran 6 verbindenden Bohrung 8 versehen ist. Eine weitere Bohrung 9 stellt die Verbindung des Raumes oberhalb der Membran 6 mit dem Abflußraum des Ventils her. Die Bohrung 8 besitzt eine zusätzliche kleine, seitliche Anschlußbohrung 10, die durch ein Sieb 11 gegen Verunreinigungen geschützt ist. Gegen große Drücke wird die Membran 6 durch eine ringförmige Stütze 12, die der Membranform angepaßt ist, geschützt. Beim öffnen des Ventils wird durch den Magnetanker 5 die Bohrung 9 freigegeben; der Druck oberhalb der Membran 6 entspannt sich über die Bohrung 9, und der von unten gegen die Membran 6 wirkende Druck des Mediums öffnet nunmehr das Ventil. Die Öffnungszeit ist wesentlich vom Größenverhältnis der beiden Bohrungen 8 und 9 abhängig.The valve is formed by the lower part of the housing 1, the upper part 2 with the guide tube 3 and the solenoid 4, the armature 5 and the membrane 6. which by an embedded metal part on the seat can be reinforced. The membrane 6 has a compressible one protruding into the inflow space Approach 7, which connects the inflow space of the valve with the space above the membrane 6 with a Hole 8 is provided. Another hole 9 connects the space above the membrane 6 with the outflow space of the valve. The hole 8 has an additional small, lateral one Connection bore 10, which is protected against contamination by a sieve 11. Against great pressures the membrane 6 is protected by an annular support 12 which is adapted to the shape of the membrane. When the valve is opened, the hole 9 is released by the magnet armature 5; the pressure above the membrane 6 relaxes via the bore 9, and that from below against the membrane 6 Acting pressure of the medium now opens the valve. The opening time depends largely on the size of the two holes 8 and 9.

Beim Schließen sperrt der Magnetanker 5 die Bohrung 9, der Raum oberhalb der Membran 6 steht jedoch mit dem Zuflußraum über die Bohrungen 10 und 8 in Verbindung, wodurch ein Nachströmen des Mediums in den Raum über der Membran 6 ermöglicht ist. Dadurch wird die Membran 6 entgegengesetzt der Strömungsrichtung des Mediums in Bewegung gesetzt. Die Zeit dieser Schließbewegung ist dabei zwangläufig vom Querschnitt der Bohrung 8 abhängig. Kurz vor der Schließstellung sperrt das Gehäuse 1 die Bohrung 8 des Ansatzes 7, so daß nunmehr die Schließbewegung von der Durchflußmenge, die durch die kleinere Seitenbohrung 10 noch fließt, bestimmt wird. Gleichzeitig wird durch die Zusammendrückung des Ansatzes 7 eine weitere Bremsung erreicht. Der die Bohrung 10 tragende Teil der Membran 6 wird bei der restlichen Schließbewegung kurz vor dem völligen Abschluß der Strömung geringfügig zusammengedrückt. When closing, the armature 5 blocks the bore 9, but the space above the membrane 6 is with the inflow space via the bores 10 and 8 in connection, whereby an after-flow of the medium is made possible in the space above the membrane 6. As a result, the membrane 6 is opposite to that Direction of flow of the medium set in motion. The time of this closing movement is inevitable depends on the cross-section of the bore 8. Shortly before the closed position, the housing 1 blocks the Bore 8 of the approach 7, so that now the closing movement of the flow rate through the smaller side bore 10 is still flowing, is determined. At the same time is due to the compression the approach 7 achieved a further braking. The part of the membrane 6 carrying the bore 10 becomes slightly compressed during the rest of the closing movement shortly before the flow is completely closed.

In Fig. 2 ist das Ventil entsprechend der Fig. 1 in geöffneter Stellung dargestellt.In Fig. 2, the valve is shown in accordance with FIG. 1 in the open position.

Fig. 3 zeigt dasselbe Ventil mit einer zusätzlichen einstellbaren Drosselschraube 13 und Dichtung 14. Hierdurch ist es möglich, die Bremsung besonders fein einzustellen. Dabei kann durch eine konische Ausbildung der Spitze der Drosselschraube 13 die Bremsung stetig geändert werden.3 shows the same valve with an additional adjustable throttle screw 13 and seal 14. This makes it possible to set the braking particularly finely. This can be done by a conical Formation of the tip of the throttle screw 13, the braking can be changed steadily.
