Description

Differentialmanometer Differentialmanometer für Dampfmesser und ähnliche Strömungsmesser werden vorherrschend mit einem [)-Rohr, wenn auch in den mannigfachsten Abwandlungen, gebaut. Bei einer häufig verwendeten Bauart wird der eine Schenkel von dem anderen Schenkel umschlossen, wie es die Abbildung zeigt. In das äußere Gefäß i ist ein Schwimmertopf a so eingepaßt, daß die oberen Ränder bündig miteinander abschließen. Eine gemeinsame Dichtung 3, welche durch das Kopfstück aufgepreßt wird, dichtet dann ,sowohl beide Gefäße gegen die äußere Atmosphäre wie auch gegen den zwischen ihnen herrschenden Differenzdruck.Differential manometer Differential manometer for steam gauges and similar Flow meters are predominantly made with a [) tube, albeit in the most varied of ways Modifications, built. One of the legs is a frequently used type of construction enclosed by the other leg, as shown in the illustration. In the outer In vessel i, a float bowl a is fitted in such a way that the upper edges are flush with one another to lock. A common seal 3, which is pressed on through the head piece, then seals both vessels against the external atmosphere as well as against the differential pressure between them.

Auch bei derartigen Bauarten war es bisher üblich, die Kurzschlußv erbindung, welche bei allen Strömungsmanometern zum Druckausgleich bei der Prüfung des Nullpunktes benötigt wird, in den äußeren Zuleitungen zum Meßgerät anzubringen. Das ergibt jedoch immer eine umständliche und kostspielige Rohrführung und außerdem ein Zusatzgerät, welches nicht mit dem eigentlichen Meßgerät organisch verbunden ist.Even with such types of construction, it has been customary to use the Kurzschlussv connection, which is used on all flow manometers to equalize pressure during the test of the zero point is required to be attached in the external supply lines to the measuring device. However, this always results in a cumbersome and expensive pipe routing and also an additional device which is not organically connected to the actual measuring device is.

Erfindungsgemäß wird der gleiche Zweck auf einfachere Weise dadurch erreicht, daß die Kurzschlußverbindung durch eine Öffnung 6 in der Wand des Schwimmertopfes gebildet wird. Während des Betriebes ist diese Öffnung durch einen Ventilkegel verschlossen, dessen Schaft 7 durch eine Stopfbüchse 5 in der Wand des äußeren Gefäßes herausgeführt ist. Will man die Kurzschlußverbindung herstellen, so schraubt man einfach den Ventilkegel 6 auf.According to the invention, the same purpose is thereby achieved in a simpler manner achieved that the short-circuit connection through an opening 6 in the wall of the float pot is formed. During operation, this opening is closed by a valve cone, the shaft 7 of which is led out through a stuffing box 5 in the wall of the outer vessel is. If you want to make the short-circuit connection, you simply screw the valve cone 6 on.

Da bei der beschriebenen Bauweise das äußere Gefäß i und der Schwimmertopf z mit metallischen Paßflächen aufeinandersitzen, kann auch ein Nachziehen der Dichtung 3 keine nachträgliche Verschiebung der beiden Gefäße gegeneinander hervorrufen.Since in the construction described the outer vessel i and the float bowl z with metallic mating surfaces on top of each other, the seal can also be tightened 3 do not cause any subsequent displacement of the two vessels against each other.
