Description

Bimetallischer, schraubenförmig gewundener Körper für Wärmemeß- und -regelvorrichtungen. Die Erfindung betrifft einen schraubenförmig gewundenen bimetallischen Körperfür W ärmemeß- und -regelvorrichtungen. Das Neue besteht darin, daß er aus zwei inein# andergesteckten und miteinander fest verbundenen Metallrohren von verschiedenem Wärineausdehnungskoeffizienten besteht, die schraubenförmig aufgeschnitten sind und dadurch die Form eines schraubenförmig aufgewickelten bimetallischen Bandes erhalten. Man hat es hierbei in der Hand, die Schraubengänge breiter oder schmäler zu gestalten, abhängig von der geforderten Stabilität und den Lasten, welche bewegt werden sollen.Bimetallic, helically wound body for heat measurement and -control devices. The invention relates to a helically wound bimetallic Body for heat measuring and regulating devices. The new thing is that he is made of two nested and firmly connected metal pipes of different kinds There is thermal expansion coefficient, which are cut helically and thereby the shape of a helically wound bimetallic tape obtain. You have it in your hand, the screw threads wider or narrower to design, depending on the required stability and the loads that move should be.

In der Abbildung ist eine Ausführungsform beispielsweise dargestellt.An example of an embodiment is shown in the figure.

Abb. i zeigt eine Ansicht des bimetallischen Körpers, welche in diesem Beispiel zylindrisch dargestellt ist, Abb. a einen Querschnitt.Fig. I shows a view of the bimetallic body, which in this Example is shown cylindrical, Fig. A a cross section.

Abb.3 zeigt zwei gleichartige, ineinandergesteckte Arbeitskörper und Abb. q. mehrere ineinandergesteckte Arbeitskörper mit wechselweise angeordneten Metallen.Fig.3 shows two working bodies of the same type and nested one inside the other Fig.q. several nested working bodies with alternately arranged Metals.

Der äußere Teil tt des bimetallischen Ausdehnungskörpers ist mit dem inneren Teil b in bekannter Weise fest verlötet, verschweißt, oder sie sind aufeinandergewalzt; c und d sind am inneren. und äußeren Rohr angebrachte Zeiger, e ist ein Befestigungsstreifen.The outer part tt of the bimetallic expansion body is with the inner part b firmly soldered, welded, or rolled onto one another in a known manner; c and d are on the inside. and pointer attached to the outer tube, e is a fastening strip.

Die Wirkungsweise ist die folgende: Das Medium (Dampf, heißes Wasser, heiße Luft oder wie es sonst heißen mag) umspült den bimetallischen Körper außen, innen und zwischen den einzelnen Schnittflächen und verursacht durch das ungleiche Ausdehnungsvermögen der Metalle eine Drehrichtung, welche je nach dem Verwendungszweck in horizontaler Richtung beibehalten oder in eine vertikale umgesetzt werden kann. Wird das Medium ausgeschaltet, dann kehrt der bimetallische Arbeitskörper in seine Ruhelage zurück.The mode of action is as follows: The medium (steam, hot water, hot air or whatever it may be called) washes around the bimetallic body on the outside, inside and between the individual cut surfaces and caused by the unequal Expansibility of metals a direction of rotation, which depends on the intended use can be maintained in the horizontal direction or converted into a vertical direction. If the medium is switched off, the bimetallic working body returns to its Rest position back.

je enger die Rohre schraubenförmig aufgeschnitten sind, um so größer ist naturgemäß die Wärmeempfindlichkeit.the narrower the tubes are cut in a helical shape, the larger is naturally the sensitivity to heat.
