Description

Dampfmesser mit Schwebekegel .in ringförmiger IVießöffnung. Die Erfindung betrifft einen Dampfmesser, bei dem in einer ,Meßöffnung ein Kegel durch den Strömungsdruck in der Schwebe gehalten wird, dergestalt, daß die Stellung dieses Kegels ein Maß für die Menge des in der Zeiteinheit durchströmenden Dampfes ist.Steam meter with floating cone in a ring-shaped pouring opening. The invention relates to a steam meter in which a cone in a measuring opening is caused by the flow pressure is held in suspension in such a way that the position of this cone is a measure is the amount of steam flowing through in the unit of time.

Die Erfindung besteht darin, daß der Dampfstrom durch zwei Meßöffnungen von verschiedenem Querschnitt mit je einem Schwebekegel, die starr miteinander verbunden sind, geteilt wird und die Teilströme hinter den Meßöffnungen wieder vereinigt werden. Hierdurch wirkt auf diesen Doppelkegel nur der Unterschied der Strömungsdrücke, die für jeden Einzelkegel in Frage kommen. Durch geeignete Bemessung des Unterschieds im Querschnitt der beiden Meßöffnungen hat man es in der Hand, die Größe des resultierenden Druckes auf den Doppelkegel beliebig zu gestalten..The invention consists in that the steam flow through two measuring openings of different cross-sections, each with a floating cone, which are rigidly connected to one another are divided and the partial flows are reunited behind the measuring openings. As a result, only the difference in flow pressures acts on this double cone, which come into question for each individual cone. By properly measuring the difference In the cross-section of the two measuring openings you have it in your hand, the size of the resulting Pressure on the double cone as desired.

Wenn z. B. bei den älteren Bauarten mit einer Meßöffnung von maximal ioo qcm ein zulässiger Strömungsüberdruck von o,3 kg/qcm zugrunde gelegt wurde, so entstand ein Gesamtdruck auf den Kegel von 3o kg. Das Schwebegleichgewicht konnte daher nur durch einen Kegel von 30 kg Gewicht erzielt werden. Dies ergab ungünstige Massenwirkungen und großen Raumbedarf. Beim Gegenstand der Erfindung kann man das Gewicht *des Kegels leicht auf den zehnten Teil vermindern, indem man z. B. der oberen Öffnung 55 qcm, der unteren 45 qcm maximalen Durchströmungsquerschnitt gibt. Der Strömungsdruck von 0,3 kg/qcm wird dann nur für 55 - 45 = io qcm wirksam, es genügt also schon ein Doppelkegel von 3 kg Gewicht zur Erzielung des Schwebe-Bleichgewichts. Die Bauart wird gedrungener, und ihre Einzelteile werden leichter.If z. If, for example, a permissible excess flow pressure of 0.3 kg / cm 2 was used as a basis for the older designs with a measuring opening of a maximum of 100 square cm, a total pressure of 30 kg was created on the cone. The levitation equilibrium could therefore only be achieved with a cone weighing 30 kg. This resulted in unfavorable mass effects and large space requirements. When the subject of the invention you can easily reduce the weight * of the cone to the tenth part by z. B. the upper opening 55 sq cm, the lower 45 sq cm maximum flow cross-section. The flow pressure of 0.3 kg / square cm is then only effective for 55 - 45 = 10 square cm, so a double cone weighing 3 kg is sufficient to achieve the floating bleaching weight. The design becomes more compact and its individual parts are lighter.

Die Zeichnung stellt ein Ausführungsbeispiel des Erfindungsgegenstandes dar. Der Dampf strömt durch den Flansch i .in den Dampfmesser in der Pfeilrichtung ein, teilt sich und durchströmt nach oben und unten die beid Meßöffnungen 2 und 3, in denen die starr v# bundenen beiden Kegel 4 und 5 sich auf und ab bewegen können. Der geteilte Dampfstrom vereinigt sich wieder und verläßt den Messer durch Flansch 6. Die Stellung des Doppelkegels 4, 5 wird in bekannter Weise außen an einem Zeigerwerk sichtbar gemacht, indem der Schwebekegel bei seinem Ausschlag mittels der Verbindungsstange io einen in einer Drehstopfbüchse 7 gelagerten Hebel 8 dreht, auf dessen Achse außen der Zeiger 9 sitzt. Eine bekannte Dämpfungseinrichtung ix. verhindert ruckweise Bewegungen des Doppelkegels 4, 5. Die Kegel können durch flache Scheiben, die in konischen Öffnungen sich bewegen, ersetzt werden, - auch können flache Scheiben über zylindrische Öffnungen schweben. Der Messer kann ferner auch der Messung von Gas- oder Flüssigkeitsmengen dienen. .The drawing represents an embodiment of the subject matter of the invention The steam flows through the flange i. into the steam meter in the direction of the arrow one, divides and flows through the two measuring openings 2 and upwards and downwards 3, in which the rigidly connected two cones 4 and 5 can move up and down. The split steam stream reunites and exits the knife through the flange 6. The position of the double cone 4, 5 is in a known manner on the outside of a pointer mechanism made visible by the floating cone at its deflection by means of the connecting rod io a lever 8 mounted in a rotary stuffing box 7 rotates on the outside of its axis the pointer 9 is seated. A known damping device ix. prevents jerks Movements of the double cone 4, 5. The cones can be replaced by flat washers that are in conical openings can move, be replaced, - also can flat disks float over cylindrical openings. The knife can also measure Serve gas or liquid quantities. .
