Description

Sicherung gegen unberechtigte Gasentnahme für Gasmesser mit Schiebersteuerung. Damit bei falsch angeschlossenen Gasmessern mit Schiebersteuerung das Getriebe nicht rückwärts läuft, ist bei diesen Gasmessern gewöhnlich ein Sperrzahn vorgesehen, der die Umdrehung der Steuer- oder Kurbelwelle nur in der zulässigen Drehrichtung gestattet und bei verkehrtem Anschluß den Gasmesser und damit auch das Zählwerk stillsetzt. Wird aber ein gewisser, vom Gewicht der Schieber abhängiger Gasdruck überschritten, dann wirkt die Einrichtung nicht mehr gegen unberechtigte Gasentnahme, weil die Schieber abgehoben werden.Protection against unauthorized gas extraction for gas meters with slide control. This means that if gas meters with valve control are incorrectly connected, the gearbox will not operate runs backwards, these gas meters usually have a ratchet tooth, the rotation of the control or crankshaft only in the permissible direction of rotation permitted and, if the connection is wrong, the gas meter and thus also the counter stops. But there will be a certain gas pressure depending on the weight of the slide exceeded, then the device no longer works against unauthorized gas extraction, because the slides are lifted.

Gegenstand der Exfindung ist eine Einrichtung, die vom Schiebergewicht völlig unabhängig, ist, bei der also die Sicherung nicht von dem Betrage des Schieberdruckes auf den Schieberspiegel abhängt. Der Gasmesser nach der Erfindung kennzeichnet sich dadurch, daß in den ordnungsgemäßen Stromweg des Gases ein bei umgekehrtem Wege den Durchgang verschließendes Rückschlagmittel eingeschaltet isst. Das kann eine Kugel oder ein Ventil oder, was das zweckmäßigste ist, eine Klappe sein. Ein Beispiel eines Gasmessers mit Rückschlagklappe ist auf zier Zeichnung dargestellt. 3 ist die Einströmleitung in den Verteilkasten q. mit dem Schieberwerke 5. Der übergang von der Leitung 3 zum Kasten ¢ geht über einen 'Stutzen 6 vor sich, dessen Mündung 7 abgeschrägt ist. Vor dieser Mündung hängt bei 8 beweglich angeschlossen eine Rückschlagklappe 2.The subject of the invention is a device that depends on the weight of the slide is completely independent, so the backup is not of the The amount of the slide pressure on the slide mirror depends on. The gas meter after the invention is characterized in that in the proper current path of the Gas switched on a non-return means that closes the passage in the opposite direction eats. It can be a ball or a valve or, which is the most convenient, one Shut up. An example of a gas meter with a non-return valve is on the ornamental drawing shown. 3 is the inflow line into the distribution box q. with the gate valve 5. The transition from the line 3 to the box ¢ goes through a 'nozzle 6, whose mouth 7 is beveled. In front of this mouth hangs at 8 movably connected a non-return valve 2.

Ist der Gasmesser falsch angeschlossen, will also das Gas, nachdem es bei verhältnismäßig hohem Drück den Schieber abgehoben hat, in Richtung des gestrichelt eingezeichneten Pfeiles p durch die Leitung 3 abströmen, so schließt die Klappe 2 den Eingang zum Stutzen 6 ab. Entsprechend würde eine Kugel oder ein Ventil bei. geeigneter Anordnung das Rückschlagmittel darstellen. Sie würden dann auf ihren Sitz getrieben und den Durchgang unterbrechen.If the gas meter is connected incorrectly, the gas will after it has lifted the slide at a relatively high pressure, in the direction of the dashed line drawn arrow p flow off through the line 3, the flap closes 2 the entrance to the nozzle 6. Correspondingly, a ball or a valve would be used. represent the non-return device in a suitable arrangement. They would then be on theirs Driven seat and interrupt the passage.

Das Rückschlagmittel kann an beliebiger Stelle im Innern des Gasmessers sitzen, zweckmäßig jedoch so, daß es von außen nicht zugänglich ist und seine offene Stellung sich nicht feststellen läßt.The non-return device can be placed anywhere inside the gas meter sit, but expediently so that it is not accessible from the outside and its open Position cannot be determined.
