Description

Bei Gasdruckreglern, die mit einem Steuerregler versehen sind, bildet sich beim Einschalten des Vordruckes, besonders wenn ein durch eine größere Leitung bedingter großer Niederdruckraum vorhanden ist, im Steuerraum oberhalb der Membran des Gasdruckreglers ein erheblicher Staudruck, der bis zur Höhe des Vordruckes anwachsen kann. Dabei wird das Ventil des Hauptreglers voll geöffnet. Wird nun niederdruckseitig der durch den Steuerregler eingestellte Druck erreicht, so wird wohl ein weiterer Zustrom des Vordruckes in den Steuerdruckraum des Reglers abgesperrt, aber die Membran des Hauptreglers, die nun in höchster Öffnungsstellung steht, kann nicht sofort und dann nur sehr langsam zurückgehen in dem Maße, wie die enge Dosierungsbohrung zwischen Steuerraum und Arbeitsraum es zuläßt. Inzwischen hat sich aber im Niederdruckraum des Reglers ein höherer Druck gebildet, der bis zur Vordruckhöhe ansteigen kann. Derartige Einschaltspitzen gefährden niederdruckseitig angeschlossene Geräte und müßten darum vermieden werden.In the case of gas pressure regulators that are equipped with a control regulator, forms when switching on the form, especially if a larger line conditional large low-pressure chamber is available, in the control chamber above the membrane the gas pressure regulator creates a considerable back pressure, which grows up to the level of the pre-pressure can. The main regulator valve is fully opened. Is now on the low pressure side reaches the pressure set by the control regulator, it will probably be another The inlet pressure into the control pressure chamber of the regulator is shut off, but the diaphragm of the main regulator, which is now in the highest opening position, cannot immediately and then go back only very slowly to the extent that the narrow metering hole between the control room and the work area. In the meantime, however, in the low-pressure room of the regulator creates a higher pressure that can rise to the pre-pressure level. Such inrush peaks endanger devices and devices connected on the low pressure side should therefore be avoided.

Die Erfindung betrifft eine diesem Zweck dienende Vorrichtung. Sie besteht darin, daß ein in einer Ausgleichleitung zwischen dem Steuerraum des Hauptreglers und dem Niederdruckraum vorgesehenes Ventil mit dem Regelglied (Membran, Kolben o. dgl.) des Steuerreglers so gekuppelt ist, daß bei einem die Belastungseinstellung der Steuermembran überschreitenden Druck dieses Ventil geöffnet wird. Dadurch kann sich bei erreichtem Arbeitsdruck ein überhöhter Steuerdruck sofort ausgleichen, so daß das Hauptventil des Reglers bei der geringsten überschreitung des Arbeitsdruckes abschließt und die Einschaltspitze vermieden wird.The invention relates to a device serving this purpose. she is that one in a compensation line between the control room of the main controller and the low-pressure chamber provided valve with the control element (membrane, piston o. The like.) The control regulator is coupled so that the load setting for one the pressure exceeding the control diaphragm this valve is opened. This can If the working pressure is reached, an excessive control pressure will immediately equalize, so that the main valve of the regulator at the slightest excess of the working pressure completes and the inrush peak is avoided.

Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes in einem- senkrechten Schnitt.The drawing shows an embodiment of the subject matter of the invention in a vertical section.

Es bezeichnet i die Membran, 2 die Entspannungsdüse, 3 den Steuerraum, 4 den Arbeitsraum, den Gaseintrittsstutzen auf der Vordruckseite und 6 den Austrittsstutzen des auf den Arbeitsdruck entspannten Gases auf der Niederdruckseite des Hauptreglers. Vom Arbeitsraum .1 zum Steuerraum 3 führt eine durch die Membran i gehende Dosierungsbohrung 7. Der Steuerregler 8 ist durch eine vor seiner Entspannungsdüse 9 einmündende Leitung io mit der Vordruckseite und durch eine hinter der Entspannungsdüse 9 einmündende Leitung 12 mit der Niederdruckseite des Hauptreglers verbunden.It denotes i the membrane, 2 the expansion nozzle, 3 the control room, 4 the working space, the gas inlet nozzle on the upstream pressure side and 6 the outlet nozzle of the gas expanded to the working pressure on the low-pressure side of the main regulator. From the working chamber .1 to the control chamber 3 there is a metering bore going through the diaphragm i 7. The control regulator 8 is through a line opening in front of its expansion nozzle 9 io with the pre-pressure side and through one opening behind the expansion nozzle 9 Line 12 connected to the low pressure side of the main regulator.

Das Ventil 13 der Entspannungsdüse 9 wird durch die Membran 14 des Steuerreglers geöffnet, die unter der Einwirkung einer auf den Steuerdruck eingestellten Feder 15 steht. Die Membran 14 ist zu diesem Zweck mit einem am Gehäuse 8 gelagerteri einarmigen Hebel 16 verbunden, gegen den die Spindel 17 des Steuerventils 13 kraftschlüssig anliegt. Der Steuerraum 18 des Steuerreglers steht durch eine Leitung i9 in offener Verbindung mit dem Steuerraum 3 des Hauptreglers. Der mit der Membran 14 verbundene Hebel 16 greift auch an der Spindel 20 eines Ventils 21 an, das in einer Leitung 22 angeordnet ist, die den Steuerraum i8 des Steuerreglers mit seinem Gehäuseraum 23 verbindet, der seinerseits durch die Leitung 12 in offener Verbindung mit dem Niederdruckraum des Hauptreglers steht.The valve 13 of the expansion nozzle 9 is through the membrane 14 of the Control regulator opened under the action of a set on the control pressure Spring 15 stands. The membrane 14 is for this purpose with a mounted on the housing 8 one-armed lever 16 connected against which the spindle 17 of the control valve 13 frictionally is applied. The control room 18 of the control regulator is open through a line i9 Connection to control room 3 of the main controller. The one connected to the membrane 14 Lever 16 also engages the spindle 20 of a valve 21 which is in a line 22 is arranged, which the control room i8 of the control regulator with its housing space 23 connects, which in turn through the line 12 in open communication with the The main controller's low-pressure chamber is in place.
