Description

Bei bekannten Gasdruckreglern besteht der Nachteil, daß der Gasdruck in der Verbrauchsleitung (Hinterdruck) bei verringertem Verbrauch bis zu Nullentnahme sehr stark ansteigt. Die Kennlinie des Hinterdrucks verläuft von einem gewissen Mindestverbrauch ab, der vom Vordruck abhängig ist, etwa in Form einer steilen Parabel mit kleinem Parameter. Diese Erscheinung rührt daher, daß der hohe Vordruck so lange durch das Ventil schlägt, bis der Hinterdruck groß genug ist, um den erforderlichen Schließdruck auszuüben. Dieser hohe Hinterdruck bei Nullentnahme ist sehr unangenehm, weil die vorhandenen Einrichtungen, z. B. Schlauchanschlüsse, unter Umständen "unzureichend sind, d.h. dem erhöhten Hinterdruck nicht standhalten und zu Gasausströmungen Anlaß geben.Known gas pressure regulators have the disadvantage that the gas pressure in the consumption line (Outlet pressure) increases very sharply with reduced consumption up to zero extraction. The characteristic of the outlet pressure depends on a certain minimum consumption, which depends on the form is, for example, in the form of a steep parabola with a small parameter. This phenomenon is touching therefore that the high admission pressure beats through the valve until the outlet pressure is high is enough to apply the required closing pressure. This high back pressure with zero removal is very uncomfortable because the existing facilities, such. B. Hose connections, under certain circumstances "inadequate i.e. cannot withstand the increased downstream pressure and lead to gas escapes To give reason.

:Man hat bereits vorgeschlagen, an dem Regler einen verstellbaren Magneten vorzusehen, der auf das Regelorgan eine zusätzliche Schließkraft ausübt und mit dem die Größe der zusätzlichen Schließkraft nach Zusammenbau. des Reglers ohne weiteres verstellt werden kann.: It has already been proposed to provide an adjustable magnet on the regulator, which exerts an additional closing force on the control element and with which the size of the additional closing force after assembly. of the controller can be easily adjusted.

Die Erfindung besteht darin, daß bei einem solchen Regler der · Magnet selbst als Schraube ausgebildet ist. In dieser Schraube kann zweckmäßigerweise das Atemloch des Reglers angeordnet sein.The invention consists in that in such a controller the magnet itself as Screw is formed. In this screw, the breathing hole of the Regulator be arranged.

"Die erfindungsgemäße Ausbildung· des Magneten an einem entsprechenden Regler ist in der Zeichnung schematisch dargestellt."The inventive training · des Magnet on a corresponding controller is shown schematically in the drawing.

/ ist der Einlaßstutzen für den Vordruck, g der Auslaß für den Hinterdruck. Das ReglerventilA wird durch die Membran/ getragen, auf die der Vordruck wirkt. Mit der Membran i ist ein Anker k verbunden, der gleichzeitig als Ventilbelastung dient. Der zugehörige Magnet m ist an dem Reglergehäuse befestigt und enthält zugleich die Atemöffnung n. Erforderlichenfalls kann man natürlich Magnet und Anker vertauschen. Um ein Kleben zwischen Magneten und Anker 'zu verhindern, wird zweckmäßig einer dieser Teile mit einer unmagnetischen Schicht, z. B. einem nachgiebigen Gummibelagΰ, versehen. Bei dieser Anordnung sind Magnet und Anker so weit voneinander entfernt, daß sie go erst dann wirksam werden, wenn das Ventil sich der Schließstellung nähert und der Gasverbrauch einen bestimmten Mindestbetrag erreicht bzw. unterschritten hat. Um den Magneten m bequem einstellen zu können, ist er als Schraube ausgebildet./ is the inlet connection for the inlet pressure, g the outlet for the outlet pressure. The regulator valve A is carried by the diaphragm / on which the inlet pressure acts. An armature k is connected to the diaphragm i and simultaneously serves as a valve load. The associated magnet m is attached to the regulator housing and at the same time contains the breathing opening n. If necessary, the magnet and armature can of course be exchanged. In order to prevent sticking between the magnet and armature, one of these parts is expediently coated with a non-magnetic layer, e.g. B. a resilient rubber covering ΰ provided. In this arrangement, the magnet and the anchor are so far apart that they g o become active only when the valve approaches the closed position and the gas consumption has reached a certain minimum amount or undershot. In order to be able to easily adjust the magnet m , it is designed as a screw.
