Description
Die Erfindung betrifft einen Verdampfungsthermostat zur Regelung des Durchflusses von strömenden Medien, deren Temperaturen in der Nähe ihrer Siedepunkte liegen, bestehend aus einem im strömenden Medium liegenden Dehnkörper, der nur teilweise mit einer abgemessenen Menge Verdampfungsflüssigkeit gefüllt ist, deren Siedetemperaturen bei allen betriebsmäßig vorkommenden Drücken ganz oder annähernd mit denjenigen des durchströmenden Mediums übereinstimmen.The invention relates to an evaporation thermostat for controlling the Flow rate of flowing media whose temperatures are close to their boiling points lying, consisting of a stretch body lying in the flowing medium, which is only partially is filled with a measured amount of evaporation liquid, its boiling point for all operationally occurring pressures completely or approximately with those of the medium flowing through.
Bei derartigen Verdampfungsthermostaten ist es erforderlich, die einzubringende Verdampfungsflüssigkeit richtig zu bemessen, da schon kleine überschüsse bei Überhitzung zu Überdruck und dadurch zum Zerplatzen des Thermostaten führen und geringe Unterschreitungen der festgelegten Füllmenge seine Regeleigenschaften nachteilig verändern. Um dieser Schwierigkeit zu begegnen ist es bekannt, zum überlastungsschutz des Dehnkörpers der Verdampfungsflüssigkeit einen vielfach größeren Anteil einer Zusatzflüssigkeit beizugeben, deren Verdampfungstemperatur wesentlich höher liegt als die des durchströmenden Mediums.With such evaporation thermostats it is necessary to introduce the Correctly dimensioning the evaporation liquid, as there are even small surpluses in the event of overheating lead to overpressure and thus to bursting of the thermostat and small undershoots change its control properties disadvantageously in relation to the specified filling quantity. To this Difficulty encountered, it is known to protect the strainer from overload the evaporation liquid a much larger proportion of an additional liquid to be added, the evaporation temperature of which is significantly higher than that of the flowing through Medium.
Es ist jedoch sehr schwierig, bei derartigen Thermostaten die erforderliche Menge Füllmediums genau zu bemessen und in den Thermostaten einzubringen.However, it is very difficult to obtain the required temperature in such thermostats Measure the amount of filling medium precisely and introduce it into the thermostat.
Die Erfindung hat sich nun die Aufgabe gestellt, das dosierte Füllen von Verdampfungsthermostaten Im Behälter befindet sich unterhalb der Thermostaten der Füllstoff. Der Behälter wird sodann geschlossen, evakuiert und das Kippregal von außen betätigt. Die Thermostaten fallen in den Füllstoff, welcher die Auswölbungen 10 auffüllt. Darauf wird der Behälter geöffnet, die Thermostaten herausgenommen und verschlossen.The invention has now set itself the task of the metered filling of evaporation thermostats. The filler is located in the container below the thermostats. The container is then closed, evacuated and the tilting rack operated from the outside. The thermostats fall into the filler, which fills the bulges 10. The container is then opened, the thermostats removed and closed.
Das Füllmedium kann z. B. aus einem Gemisch von beispielsweise 2,14g Wasser/Verdampfungsflüssigkeit und 100 g Glyzerin als zusätzliche Flüssigkeit bestehen.The filling medium can, for. B. from a mixture of for example 2.14g Water / evaporation liquid and 100 g glycerine as an additional liquid.
Die Verdampfungsflüssigkeit ist hierbei so bemessen, daß sie bei Sättigungstemperatur des umgebenden Mediums restlos verdampft. Tritt in der betreffenden Dampfanlage überhitzter Dampf auf, der den Thermostaten umspült, so kann keine weitere Flüssigkeit im Thermostaten verdampfen und diesen etwa zum Platzen bringen. Die zusätzliche FIüssfgkeit kann hierbei ein beliebiges hohes Vielfaches der Verdampfungsflüssigkeit betragen.The evaporation liquid is dimensioned so that it is at saturation temperature of the surrounding medium evaporated completely. Occurs in the steam system concerned superheated steam, which washes around the thermostat, so no more liquid can evaporate in the thermostat and cause it to burst. The additional The liquid can be any high multiple of the evaporation liquid be.
Selbstverständlich ist dieses Verfahren und diese Anordnung auch für Verdampfungsthermostaten geeignet, deren Verdampfungsflüssigkeit anders zusammengesetzt ist als in dem erwähnten Beispiel oder deren Füllung ausschließlich aus Verdampfungsflüssigkeit besteht.Of course, this method and this arrangement is also for Evaporation thermostats are suitable whose evaporation liquid has a different composition is as in the example mentioned or its filling exclusively from evaporation liquid consists.
