Description
Klemmbuchse aus Kunststoff für Wasserzähler.Clamping sleeve made of plastic for water meters.
Gegenstand der Erfindung ist eine Buchse aus Kunststoff, die zur elektrischen Isolierung einer Stellschraube gegenüber dem Wasserzählergehäuse dient.The invention relates to a socket made of plastic, which is used for electrical Is used to isolate an adjusting screw from the water meter housing.
Im Wasserzählerbau ist häufig die Aufgabe gestellt, eine vom Wasser umströmte Stellschraube im Gehäuse anzuordnen. Beispiele hierfür sind die Befestigun4 des Grundstifts, die Regulierschraube und die Stellschraube zum Befestigen des Umschalteinsatzes bei Verbundzählern. Da nun meistens Stellschraube und Gehäuse aus verschiedenen metallischen Werkstoffen beispielsweise Stahl und Messing, Messing und Grauguß bestehen, fließt von dem Maschinenteil mit elektrochemisch höherem Potential zu dem Teil mit elektrochemisch niedrigerem Potential ein elektrischer Strom, der starke Korrosionserscheinungen hervorruft.In water meter construction, the task is often to get one from the water to arrange around the set screw in the housing. Examples of this are fastening4 the base pin, the regulating screw and the adjusting screw for fastening the switchover insert for compound meters. Since now mostly adjusting screw and housing are made of different metallic materials such as steel and brass, brass and gray cast iron, flows from the machine part with an electrochemically higher potential to the part electrochemically lower potential an electric current, the strong corrosion phenomena evokes.
Dieser korrodierende elektrische Strom ist besonders stark, Wenn das Wasser einen hohen Chlorid-und Sulfatgehalt hat.This corrosive electric current is especially strong when that Water has a high chloride and sulphate content.
Um diesem Übel abzuhelfen, wird erfindungsgemäß das Gehäuse gegenüber der Stellschraube durch eine Klemmbuchse aus Kunststoff, die an ihrer einen Seite einen Innenkonus und Schlitze aufweist, elektrisch isoliert. Die Stellschraube wird beim Einsohrauben in die Klemmbuchse~durch das Aufweiten des Innenkonus verspannt und so gegen selbständiges Lösen gesichert.To remedy this evil, according to the invention, the housing is opposite the adjusting screw through a clamping sleeve made of plastic on one side has an inner cone and slots, electrically insulated. The set screw will when screwing into the clamping bush ~ braced by expanding the inner cone and thus secured against unintentional loosening.
Auf diese Weise ist eine Arretierung der Stellachraube in Jeder gewtinschten Einschraubstellung gewährleistet.In this way, locking of the adjusting screw is desired in each case Screw-in position guaranteed.
In Fig. 1 und Fig. 2 ist ein Ausführungsbeispiel der Erfindung dargestellt.In Fig. 1 and Fig. 2, an embodiment of the invention is shown.
Die Klemmbuchse 1 ist in das Gehäuse 2 bis zum Anschlag des Bundes 3 eingeschraubt. Die Stellschraube 4 weitet beim Einschrauben in die glemmbuchse 1 den Innenkonus 5, der mit Schlitzen 6 versehen ist, auf und bewirkt sowohl ein Verspannten der Klemmbucbse 1 im Gehäuse 2 als auch eine Sicherung der Stellschraube 1 gegen selbständiges Lösen. Im Innenkonus 5 kann auch ein Innengewinde vorhanden sein, das zum Gewinde der Stellschraube 4 paßt. Gleichzeitig wird durch die Verwendung eines Kunststoffs für die Klemmbuchse 1 das Gehäuse 2 gegenüber der Stellschraube 4 elektrisch isoliert. The clamping sleeve 1 is in the housing 2 up to the stop of the federal government 3 screwed in. The adjusting screw 4 expands when it is screwed into the clamp socket 1 the inner cone 5, which is provided with slots 6, and causes both a Braced the clamping bushing 1 in the housing 2 as well as securing the adjusting screw 1 against independent loosening. An internal thread can also be present in the inner cone 5 that matches the thread of the set screw 4. At the same time through the use a plastic for the clamping sleeve 1, the housing 2 opposite the adjusting screw 4 electrically isolated.
