Gasdruckregler mit Atmungsdüsen als DatnpfungsexnrichtungGas pressure regulator with breathing nozzles as a dumping device
Die Erfindung betrifft einen Gasdruckregler mit einem Ventil und mindestens einer Membran, dem ein schnell arbeitendes Elektromagnetventil nachgeschaltet ist, wobei ein Druckraum oberhalb der Membran des Gasdruckreglers eine nach außen führende Atmungsdüse besitzt. The invention relates to a gas pressure regulator with a valve and at least one membrane to which a fast-working electromagnetic valve is connected downstream, wherein a pressure space above the membrane of the gas pressure regulator has a breathing nozzle leading to the outside.
Gasdruckregler mit einer Atmungsdüse sind bekannt. Eine Norm schreibt vor, daß beim Bruch einer Membran maximal 30 lt/h entweichen dürfen. Das ergibt bei einem Druck von 100 mb eine. Düsenbohrung von 0,3 mm, die nicht unterschritten werden sollte, da sie zum Verstopfen neigt.Gas pressure regulators with a breathing nozzle are known. A standard stipulates that if a membrane breaks, a maximum of 30 lt / h can escape to be allowed to. At a pressure of 100 mb this results in a. Nozzle bore of 0.3 mm, which should not be undercut, because it tends to become clogged.
Ein Gasdruckregler besitzt deshalb eine verhältnismäßig große Bohrung, in die eine gewendelte Feder eingesetzt, eine gewisse Dämpfung erreicht.A gas pressure regulator therefore has a relatively large bore into which a coiled spring is inserted, a certain amount Attenuation achieved.
Ein anderer bekannter Druckregler besitzt dafür eine Tellerplatte mit einer darin befindlichen kleinen· Bohrung, wobei sich beim Bruch der Membran der Teller sofort verschließend anlegt und danach nur die kleine're Bohrung die erlaubte kleine Menge noch frei läßt.Another known pressure regulator has for this purpose a plate plate with a small hole in it Rupture of the membrane of the plate immediately closes and then only the smaller hole the allowed small amount still free.

Bei den genannten Gasdruckreglern soll nur bei Bruch der Membrane verhindert werden, daß mehr Gas als erlaubt ausströmen kann..In the case of the gas pressure regulators mentioned, this should only occur if the diaphragm ruptures prevent more gas from escaping than is permitted ..
Demgegenüber hat die Erfindung bei einem Gasdruckregler der genannten Art, in Verbindung mit einem schnellschaltenden Ventil, eine wirksame Verzögerung zu schaffen.'In contrast, the invention has the aforementioned for a gas pressure regulator Kind of, in conjunction with a quick-acting valve, to create an effective delay. '
Dies wird unter Zuhilfenahme der nach der Norm genau definierten Atmungsdüse, erfindungsgemäß dadurch erreicht, daß zwei oder mehrere Atmungsdüsen, im Abstand voneinander, hintereinander geschaltet sind.This is precisely defined with the aid of the standard Breathing nozzle, according to the invention achieved in that two or several breathing nozzles are connected in series at a distance from one another.
Durch diese Maßnahme wird eine Art Kaskadenschaltung erreicht, da bei jeder Düse ein Druckabfall hervorgerufen wird und die nächste Düse gleich mit einem geringeren Druck beaufschlagt wird. Das hat zur Folge, daß in Verbindung mit einem schnellöffnenden Ventil der Gasdruckregler seinen Ventilteller langsam bewegt, weil der Raum unter der Membran sich nur gebremst ausgleichen kann.A kind of cascade connection is achieved by this measure, since a pressure drop is caused at each nozzle and the the next nozzle is immediately subjected to a lower pressure. This has the consequence that in connection with a quick opening The valve of the gas pressure regulator moves its valve disk slowly because the space under the diaphragm only slows down can compensate.
Weitere erfindungsgemäße Maßnahmen sind in den Ansprüchen 2 bis 6 beschrieben.Further measures according to the invention are set out in claims 2 to 6 described.
Die Erfindung wird nun anhand der ein Ausführungsbeispiel zeigenden
Zeichnung näher erläutert.

Die Figur 1 zeigt einen Gasdruckregler 1, der eine Feder 2, eine Membran 3, ein Ventil 4 und oberhalb eines Raumes 5 mehrere Atmungsdüsen 6 besitzt. Dem Gasdruckregler 1 nachgeschaltet befindet sich ein handelsübliches, schnell arbeitendes Elektromagnetventil 7.FIG. 1 shows a gas pressure regulator 1, which has a spring 2, a membrane 3, a valve 4 and above a space 5 has several breathing nozzles 6. Downstream of the gas pressure regulator 1 there is a commercially available, fast-working one Solenoid valve 7.
In Figur 2 sind die Atmungsdüsen 6 als einzelne Düsenkörper mit 6a, 6b und 6c und die Zwischenräume mit 8a und 8b bezeichnet. Ein Filter 9 schützt die Düsenanordnung.In Figure 2, the breathing nozzles 6 are designated as individual nozzle bodies with 6a, 6b and 6c and the spaces with 8a and 8b. A filter 9 protects the nozzle arrangement.
In Figur 3 ist eine der Atmungsdüsen 6a, 6b, 6c mit einem zusätzlichen Einstellglied 10 dargestellt. Mit diesem läßt sich der freie Durchlaß der Bohrung der Atmungsdüse verändern, das heißt, er kann eingestellt werden.In FIG. 3, one of the breathing nozzles 6a, 6b, 6c with an additional adjusting member 10 is shown. With this lets change the free passage of the bore of the breathing nozzle, that is, it can be adjusted.
Die Arbeitsweise ist folgende:The way it works is as follows:
Der Pfeil A deutet den Eingang an. Wenn das Elektromagnetventil 7 geschlossen ist, baut sich ein Druck auf, der auch die Membran 3 entgegen der Feder 2 beaufschlagt und sein Ventil 4 schließt. In dem Moment, wo das Elektromagnetventil 7 schnell öffnet, versucht die Membran 3 die Abwärtsbewegung gleichzeitig mitzumachen und ihr Ventil 4 zu öffnen, woran sie aber gehindert wird. Denn die Atmungsdüsen 6a, b, c lassen nur einen langsamen Ausgleich des Raumes 5 zu. Wobei die Membran 3 - mit Unterstützung der Feder 2 - ihren Ventilteller 4 langsam absenken kann, so daß ein langsames öffnen der gesamten Absperr- und Regeleinrichtung erfolgt.The arrow A indicates the entrance. When the solenoid valve 7 is closed, a pressure builds up, too the membrane 3 is applied against the spring 2 and its valve 4 closes. The moment the solenoid valve 7 opens quickly, the membrane 3 tries to follow the downward movement at the same time and to open its valve 4, whereupon but she is hindered. This is because the breathing nozzles 6a, b, c only allow the space 5 to be balanced out slowly. Whereby the membrane 3 - with the support of the spring 2 - can slowly lower its valve disk 4, so that a slow opening the entire shut-off and control device.
