PATENTAMT.PATENT OFFICE.
Bei manchen Verdampfungs- oder Kondensationsapparaten macht sich das Bedürfnis fühlbar, den der wahren Dampftemperatur (Uberhitzungstemperatur) entsprechenden Druck sowohl als auch den der Sattdampftemperatur entsprechenden Druck miteinander vergleichen zu können. Hierzu dient das Doppelmanothermometer, welches Gegenstand der vorliegenden Erfindung ist. Dasselbe stellt eine VereinigungThe need arises with some evaporation or condensation apparatus sensible, the pressure corresponding to the real steam temperature (superheating temperature) compare both the pressure and the pressure corresponding to the saturated steam temperature to be able to. The double manothermometer, which is the subject of this Invention is. The same thing represents a union
ίο zweier Manometer dar, auf dessen Skala die oben angegebenen Drucke bzw. die ihnen entsprechenden Temperaturen abgelesen werden können, und zwar mit Hilfe von zwei Zeigern, welche in bekannter Weise um dieselbe Achse drehbar angeordnet sind. Der eine Zeiger folgt dem Drucke, welcher der Sattdampftemperatur entspricht, zeigt also die Drucke gesättigter Dämpfe an, der andere Zeiger folgt dem Druck, weichet der wahren Dampftemperatur entspricht. ίο two pressure gauges, on whose scale the Above specified pressures or the corresponding temperatures can be read off can, with the help of two pointers, which in a known manner around the same axis are rotatably arranged. One pointer follows the pressure, which follows the saturated steam temperature corresponds, so shows the pressures of saturated vapors, the other pointer follows the pressure, which corresponds to the true steam temperature.
Die Zeichnung veianschaulicht das Doppelmanothermometer. Das Innere der Bouidonröhre α steht in offener Verbindung mit dem Innern des Dampfrohres oder Dampfgefäßes irgendwelcher Art b, so daß der in b herrschende Diuck den Zeiger S einstellt. Das Innere der Bourdon röhre c steht in Verbindung mit dem Innern des Gefäßes d, welches Flüssigkeit und Sattdampf aus dieser Flüssigkeit enthält und von den in b strömenden Dämpfen umgeben ist, so daß im Gefäß d dieselbe Temperatur vorhanden ist wie in b. Der in d herrschende Druck wird durch Zeiger U angegeben. Ist die Flüssigkeit in d von gleicher Art wie der in b enthaltene Dampf (7. B. Ammoniak), so entsteht bzw. herscht in d und c ein Druck, welcher der wahren Dampftemperatur in b entspricht und den Zeiger U einstellt. Auf der Skala sind die den Sattdampftemperaturen entsprechenden Drucke angegeben, so daß der eine Zeiger den Druck gesättigten Dampfes anzeigt, während der andere Zeiger den der wahren Dampftemperatur entsprechenden Druck anzeigt.The drawing shows the double manothermometer. The interior of the bouidon tube α is in open communication with the interior of the steam pipe or steam vessel of any kind b, so that the pressure prevailing in b sets the pointer S. The interior of the Bourdon tube c is in communication with the interior of the vessel d, which contains liquid and saturated steam from this liquid and is surrounded by the vapors flowing in b , so that the same temperature is present in the vessel d as in b. The pressure prevailing in d is indicated by the pointer U. If the liquid in d is of the same type as the vapor contained in b (7. B. ammonia), a pressure arises or prevails in d and c which corresponds to the true vapor temperature in b and which sets the pointer U. The pressures corresponding to the saturated steam temperatures are indicated on the scale, so that one needle shows the pressure of saturated steam, while the other needle shows the pressure corresponding to the true steam temperature.
