Description

Geibergeräte für Elüssigkeitsstände, welche durch elektrische Kontaktgabe die angeschlossenen Apparate steuern und deren Arbeitsweise darin besteht, daß sich in einem zur Flüssigkeit hin abgeschlessenen. Schutzrohr Quecksilberschalter befinden, die dadurch einen auf dem Schutzrohr entlang laufenden Schwimmer, welcher einen Dauermagnet enthält, betätigt werden, sind bereits bekannt (Patent 658 66Z). Der Nachteil der dort beschriebenen Anordnung besteht darin, daß sich der Schwimmer auf dem Schutzrohr nicht verdrehen darf, damit der Magnet die Quecksilberschalter sicher betätigt. Zu diesem Zweck wird meist entweder eine rechteckige Form des Schutzrohrs gewählt oder aber bei einem runden Schutzrohr ist eine Führung notwendig, die in eine entsprechende Nut des Schwimmers eingreift. Geibergeräte for Elüssigkeitsstands, which by making electrical contact control the connected devices and the way they work is that in one closed off towards the liquid. Mercury switch are located which thereby a float running along the protective tube, which a Permanent magnet, which are actuated, are already known (patent 658 66Z). Of the The disadvantage of the arrangement described there is that the float must not twist on the protective tube so that the magnet hits the mercury switch safely operated. For this purpose, either a rectangular shape of the protective tube is usually used selected or with a round protective tube a guide is necessary, which is shown in a corresponding groove of the float engages.

Um diese Nachteile, die fertigungstechnisch Schwierigkeiten machen und bei Anwendung der Anordnung in Druckgefäßen die Festigkeit nachteilig beeinflussen können, zu vermeiden, wird deshalb vorgeschlagen, an sich bekannte Quecksilberschaltröhren mit Hub-oder Tauchanker zu verwenden, die durch einen fing- -förmigen, im Schwimmer untergebrachten :tauermagnet betätigt werden. Auf diese Weise wird erreicht, daß sich der Schwimmer auf dem nun rund ausgebildeten, glatten Schutzrohr beliebig verdrehen kann, ohne die Arbeitsweise der Quecksilberschaltröhren nachteilig zu beeinflussen. Gleichzeitig wird mit der beschriebenen Kombination eine Verringerung des Rohrdurchmessers und damit eine nicht unwesentliche Werkstoffersparnis erzielt. To these disadvantages, which make manufacturing difficulties and adversely affect the strength when the arrangement is used in pressure vessels It is therefore proposed to avoid mercury interrupter tubes which are known per se With lifting or diving anchors to be used by a finger-shaped, in the float housed: dew solenoid operated. In this way it is achieved that the float can turn as desired on the smooth protective tube, which is now round can without adversely affecting the operation of the mercury interrupter tubes. At the same time, the combination described results in a reduction in the pipe diameter and thus achieved a not insignificant material saving.

Die Zeichnung erklärt- die Wirkungsweise: In dem unmagnetischen Schutzrohr a, das in die Flüssigkeit eintaucht und nach dieser hin lurch einen Boden abgeschlossen ist, befinden sich an geeigneten Stellen Quecksilberschaltröhren b mit in der Achsrichtung des Schutzrohrs verschiebbaren Ankern c, welche je nach ihrer Stellung eine leitende Verbindung zwischen den Elektroden d und e über die Quecksilberfüllungf herstellen. Um das Schutzrohr a liegt ein Schwimmer g mit einem gewissen Spiel, so daß dieser sich, auf dem Flüssigkeitsspiegel schwimmend, entsprechend dem Flüssigkeitsstand auf dem Schutzrohr a auf und ab bewegen kann. In dem Schwimmer g ist konzentrisch zum Schutzrohr a ein Dauermagnet Zt in: Form eines. Hohlzylinders mit den Polen an den Enden desselben untergebracht. Kommt bei Flüssigkeitsstandänderungen der Schwimmer g mit dem Dauermagnet h in die Nähe einer Quecksilberschaltröhre b, so wird deren Anker c in das magnetische Feld des Dauer-,magnets gezogen und führt den Stromschluß zwischen - den Elektroden d und e herbei, wie dies im unteren Teil der Zeichnung dargestellt ist. Wandert der Schwimmer g aus dem Bereich der Quecksilberschaltröhre- heraus, so geht deren Anker infolge des nunmehr fehlenden magnetischen Feldes wieder in seine Ruhelage zurück (s. obere Quecksilberschaltröhre). The drawing explains how it works: In the non-magnetic protective tube a, which is immersed in the liquid and then closed off by a bottom there are mercury interrupter tubes b at suitable points in the axial direction of the protective tube sliding armature c, which depending on their position a conductive Establish a connection between electrodes d and e via the mercury filling f. To the protective tube a is a float g with a certain amount of play, so that this floating on the liquid level according to the liquid level can move up and down on the protective tube a. In the float g is concentric to the protective tube a a permanent magnet Zt in: form of a. Hollow cylinder with the poles housed at the ends of the same. When the fluid level changes, the Float g with the permanent magnet h in the vicinity of a mercury interrupter b, see above whose armature c is drawn into the magnetic field of the permanent magnet and leads the current connection between - the electrodes d and e, as shown in the lower part the drawing is shown. If the float g moves out of the area of the mercury interrupter out, its anchor goes again due to the now missing magnetic field back to its rest position (see upper mercury interrupter).

An Stelle von Quecksilberschaltröhren, bei denen in Ruhestellung die elektrische Verbindung zwischen den Elektroden unterbrochen ist, können auch solche verwendet werden, bei denen in Ruhestellung die Elektroden leitend überbrückt sind oder auch Ausführungen Verwendung finden, bei denen der Anker auf mechanischem oder magnetischem Wege in derjenigen Lage gehalten wird, die er beim Auswandern des durch den Magnet FY hervorgerufenen Feldes einnahm. Instead of mercury interrupter tubes, which are in the rest position the electrical connection between the electrodes is interrupted, can also those are used in which the electrodes are conductively bridged in the rest position are or designs are used in which the anchor on mechanical or is held magnetically in the position in which it was when emigrating of the field caused by the magnet FY.
