Description
Mischvorrichtung für Dampf aus verschiedenen Leitungen mit verschiedenem Druck und verschiedener Temperatur Es sind verschiedene Vorrichtungen bekannt geworden, nicht nur den Druck des Dampfes, sondern auch die Temperatur desselben irgendwelchen Bedingungen des zu verwendenden Dampfes anzupassen.Mixing device for steam from different lines with different Pressure and different temperature Different devices have become known, not only the pressure of the steam, but also the temperature of any To adapt the conditions of the steam to be used.
In Dampfkraftanlagen tritt nun häufig der Fall ein, daß nicht nur ein Dampf bestimmten Druckes zur Verwendung gelangt, sondern mehrere Dämpfe von ganz verschiedener Art. Vorliegende. Erfindung ermöglicht die Ausnutzung und Verwendung beider Dampfarten für einen bestimmten Zweck, und, zwar betrifft die Erfindung ein Verfahren zum Mischen und Entspannen von Dämpfen verschiedener Temperaturen, wie z. B. der Sättigungs- und der Überhitzungstemperatur. Das Verfahren besteht darin, daß die beiden verschieden heißen Dämpfe vorerst zwecks Erreichung der verlangten Endtemperatur gemischt und darauf der gemischte Dampf auf den verlangten Druck entspannt wird.In steam power plants, the case now often occurs that not only a vapor of a certain pressure is used, but several vapors of of very different kinds. Invention enables exploitation and use Both types of steam for a specific purpose, namely, the invention relates to a Process for mixing and releasing vapors at different temperatures, such as z. B. the saturation and superheating temperature. The procedure consists in that the two vapors of different temperatures were initially required in order to achieve the required Mixed final temperature and then the mixed steam is released to the required pressure will.
Ap Hand der Zeichnung sei die Erfindung näher erläutert.The invention is explained in more detail in the drawing.
Die Abbildung zeigt eine beispielsweise Ausführung zur Durchführung des oben beschriebenenVerfahrens. DieDampfzuleitungi führt beispielsweise Dampf niedrigerer Temperatur, die Dampfzuleitung 2 solchen höherer Temperatur. Durch den eingebauten Temperaturregler 3 wird infolge größerer oder kleinerer Ausdehnung der eingeschlossenen Flüssigkeit die Membran 4 mehr oder weniger nach unten gedrückt und durch den Ventilkegel 5 mehr oder weniger Drucköl weggelassen, so daß die Feder 6 des Mischventils 7 den Kolben 8 verschiebt und je nachdem die Durchflußflächen 9 und io beidseitig des Schiebers i i entsprechend öffnet cder schließt. Nimmt die Temperatur auf der Abflußseite aus irgendeinem Grunde zu so geht die Membran 4 nach unten, der Olabfluß durch den Kegel 5 wird vergrößert, der Öldruck sinkt und der Kolben 8 wind durch die Feder 6 nach unten gedrückt; der Durchflußspalt bei 9 wird vergrößert, derjenige bei io verkleinert, so daß mehr Dampf geringerer Temperatur zuströmt und auf diese Weise auch die Mischungstemperatur verringert wird. Bei einem Fallen der Temperatur wird umgekehrt die Membran 4 durch die Feder nach oben gedrückt, der Ventilkegel s läßt weniger Drucköl abfließen und der Schieber i i wird nach ob-en geschoben.The illustration shows an example of the implementation of the method described above. The steam supply line carries steam, for example lower temperature, the steam supply line 2 such a higher temperature. Through the built-in temperature controller 3 is due to larger or smaller expansion of the trapped liquid pressed the membrane 4 more or less downwards and omitted by the valve cone 5 more or less pressure oil, so that the spring 6 of the mixing valve 7 moves the piston 8 and depending on the flow areas 9 and io on both sides of the slide i i opens cder closes accordingly. Take the Temperature on the outflow side for some reason too so the membrane 4 goes behind below, the oil outflow through the cone 5 is increased, the oil pressure drops and the Piston 8 is pressed down by the spring 6; the flow gap at 9 becomes increased, the one at io decreased, so that more steam at lower temperature flows in and in this way the mixture temperature is also reduced. At a Conversely, if the temperature falls, the membrane 4 is pushed upwards by the spring, the valve cone s allows less pressure oil to flow off and the slide i i slows down pushed up.
Der durch das Mischventil auf die richtige Temperatur gebrachte Dampf wird nunmehr durch das Druckminderventil 12 auf den richtigen Dampfdruck heruntergedrosselt. Mit dem abdampfgeitigen Raum wird durch die Leitung 13 der Druck auf die Membran 14 übertragen, welche ihrerseits den Öl.ablaßkege115 betätigt. Steigt der Druck in der besagten Leitung, so wird die Membran !q. nach unten gedrückt, und der Kegel 15 läßt mehr Drucköl wegfließen, so d2.ß die Feder r6 .des Druckminderventils 12 den Kolben 17 und damit das Ventil 18 nach unten drückt und durch größere Drosselung eine Druckverringerung erreicht. Umgekehrt wird bei Druckabnahme die Membran 14 durch die Feder nach oben gedrückt, der Öldruck steigt infolge verringerten Abflusses des Kegels 15, der Ölkolben 17 samt Ventil 18 werden gehoben und die Drosselung verringert.The steam brought to the correct temperature by the mixing valve is now throttled down to the correct steam pressure by the pressure reducing valve 12. With the space on the side of the vapor, the pressure is transmitted through the line 13 to the membrane 14, which in turn actuates the Öl.ablaßkege115. If the pressure in said line increases, the membrane becomes! Q. pressed down, and the taper 1 5 can more pressure oil to flow away, so d2.ß the spring r6 .of the pressure reducing valve 12, the piston 17 and thus pushes the valve 18 down and achieved by throttling a greater pressure reduction. Conversely, when the pressure drops, the diaphragm 14 is pressed upwards by the spring, the oil pressure rises as a result of the reduced outflow of the cone 15, the oil piston 17 together with the valve 18 are raised and the throttling is reduced.
Der notwendige ölbedarf wird durch die Pumpe 19, welche von einem Elektromotor 2o angetrieben wird, geliefert, welche das Öl aus dem Behälter 21 ansaugt; hier münden auch die Abflüsse der Regelvorrichtungen.The necessary oil requirement is through the pump 19, which is from a Electric motor 2o is driven, which sucks the oil from the tank 21; the outflows of the regulating devices also flow here.
