Für diese Ventile kann die Spülung daher nur unter Überdruck erfolgen.ahead of the environment. So far, this has been constructive not given for all cylinder valve designs. For these valves, the flushing can therefore only be performed under Overpressure.
In weiterer Ausbildung der Vorrichtung nach dem Hauptpatent (Patentanmeldung P 23 ?3 017.3) wird die Aufgabe gemäß dem Kennzeichen der Patentansprüche 2 und 3 gelöst. In vorteilhaft einfacher Weise kann dabei die Spülung zum Trocknen des Flascheninnenraumes durch Einleiten von Druckgas - es kann dies auch das Atemgas, z.B. Luft, sein - oder auch eines Spülgases erfolgen. Durch die Erwärmung verdampft evtl. vorhandene Flüssigkeit in das unter Druck stehende Gas hinein und wird nach Umschaltung des Dreiwegeventils mit dem Gas herausgespült.In a further development of the device according to the main patent (patent application P 23-3 017.3) the task solved according to the characterizing part of claims 2 and 3. The flushing can be carried out in an advantageously simple manner to dry the inside of the bottle by introducing compressed gas - this can also be done by breathing gas, e.g. air, be - or take place with a purge gas. As a result of the heating, any liquid that may be present evaporates into the lower Pressurized gas enters and is flushed out with the gas after switching the three-way valve.
Mit dem in die Leitung zur Umgebung eingebauten Taupunkthygrometer läßt sich in einfacher und sicherer Weise der noch im Gas vorhandene Feuchtigkeitsgehalt feststellen. Der Spülvorgang kann dann wiederholt werden.With the dew point hygrometer built into the line to the environment the moisture content still present in the gas can be determined in a simple and reliable manner. The rinsing process can then be repeated.
In besonders einfacher Ausführung ist das Taupunkthygrometer ein von dem Spülgas durchströmtes Gfesrohr. Auf diesem ist der beim Durchströmen niedergeschlagene Dampf sehr gut zu erkennen.The dew point hygrometer is a particularly simple design a Gfesrohr through which the purge gas flows. On this one the vapor deposited as it flows through can be seen very clearly.
Eine weitere Ausbildung nach dem Hauptpatent (Patentanmeldung P 23 23 017.3Ϊ erfolgt gemäß dem Kennzeichen des Patentanspruches 5. Hiernach ist das Dreiwegeventil durch einzelne Schaltventile in den beiden Leitungen ersetzt. Dies kann für die Bedarfsfälle- von Vorteil sein, in denen man nach dem Trocknen des Flascheninnenraumes vor dem endgültigen Füllen mit dem Atemgas A further training according to the main patent (patent application P 23 23 017.3Ϊ takes place according to the identifier of claim 5. According to this, the three-way valve is through individual switching valves in the two lines replaced. This can be an advantage if necessary be, in which one after the drying of the bottle interior before the final filling with the breathing gas
