Description

Die Erfindung-,betrifft eine weitere Ausbildung eines Niederdruckgasreglers nach Patent 815 938, bei dem ein zuverlässiger Abschluß der Drosselklappe durch eine elastische Dichtung aus Gummi od. dgl. gesichert ist. Nach dem Hauptpatent ist in die Drosselklappe eine elastische Scheibe eingesetzt, die sich beim Schließen der Drosselklappe dichtend an die Wand des Durchflußkanales legt. Damit der beabsichtigte Zweck eines zuverlässigen Abschlusses erreicht wird, muß die Drosselklappe eine genau passende elliptische Form haben. Tritt im Gebrauch eine Abnutzung der Drosselklappe ein, so kann dies dazu führen, daß die Drosselklappe nicht mehr an ihrem ganzen Umfang dicht anliegt.The invention relates to a further embodiment of a low-pressure gas regulator according to patent 815 938, in which a reliable closure of the throttle valve by an elastic seal made of rubber od. The like. Is secured. According to the main patent an elastic washer is inserted into the throttle valve, which moves when it is closed the throttle valve places sealingly on the wall of the flow channel. So the intended The purpose of a reliable conclusion is achieved, the throttle valve must have a have a perfectly fitting elliptical shape. If the throttle valve wears out during use one, this can mean that the throttle valve is no longer in its entirety Circumference fits tightly.

Die Erfindung vermeidet diese Schwierigkeiten. Sie besteht darin, daß die Abdichtung zwischen der Drosselklappe und der Wand des Durchflußkanales durch eine in die Kanalwand eingelegte Muffe aus Dichtungsmaterial erfolgt, so daß eine einfache Drosselklappe ohne Dichtungseinlage Verwendung finden kann. Durch ein Einschmiegen der Drosselklappe in die Muffe aus Dichtungsmaterial ist ein zuverlässiger Abschluß auch dann gesichert, wenn der elliptische Rand der Drosselklappe gewisse Ungenauigkeiten aufweist.The invention avoids these difficulties. It consists in that the seal between the throttle valve and the wall of the flow channel takes place through a sleeve made of sealing material inserted into the duct wall, so that a simple throttle valve without a sealing insert can be used. By nestling of the throttle valve in the sleeve made of sealing material is a reliable one Completion also secured when the elliptical edge of the throttle valve is certain Has inaccuracies.

Die Zeichnung zeigt in vereinfachter Darstellung einen senkrechten Schnitt durch den Regler. Die durch eine Membran r gesteuerte Drosselklappe 2 des Reglers ist im Eintrittsstutzen 3 des Reglergehäuses 4 eingebaut. Ihr Lager 5 befindet sich innerhalb einer im Stutzen 3 eingesetzten Büchse 6, die den zu regelnden Durchflußkanal umschließt. In diese Büchse ist eine zylindrische Muffe 2r aus Gummi oder einem anderen geeigneten Dichtstoff eingelegt. An dieser Muffe dichtet die Drosselklappe 2 in der dargestellten Schließstellung ab.The drawing shows a simplified representation of a vertical Section through the regulator. The throttle valve 2 of the controlled by a membrane r The regulator is installed in the inlet connection 3 of the regulator housing 4. Your warehouse 5 is located inside a sleeve 6 inserted in the nozzle 3, which controls the flow channel encloses. In this sleeve is a cylindrical sleeve 2r made of rubber or a another suitable sealant inserted. The throttle valve seals against this sleeve 2 in the illustrated closed position.

Die Einstellung der Drosselklappe erfolgt wie bei dem Hauptpatent durch einen Kniehebel, dessen einer Schenkel 13 gelenkig mit der Drosselklappe verbunden und dessen anderer Schenkel 14 an einem am Gehäuse befestigten Bock 15 gelagert ist. Am Gelenk 16 des Kniehebels greift eine mit dem Membranteller 22 verbundene Stange 17 an.As in the main patent, the throttle valve is adjusted by a toggle lever, one leg 13 of which is articulated to the throttle valve and the other leg 14 of which is mounted on a bracket 15 attached to the housing. A rod 17 connected to the diaphragm plate 22 acts on the joint 16 of the toggle lever.
