Description

Die Erfindung `bezieht sich auf eine Verbesserung der bisher handielsübiichen Druckminderer für Azetylengas. Man ,hatte solche Druckminderer schon mit einer Einrichtung zum Druckregeln versehen, die mit einer federbelasteten Membxan und mit einer die maximale Vorspannung der Feder begrenzenden und von. außen unzugänglichen Sperrvorrichtung arbeitet.The invention `relates to an improvement of the hitherto customary Pressure reducer for acetylene gas. You already had such pressure reducers with a device for pressure regulation provided with a spring-loaded Membxan and with a die maximum bias of the spring limiting and of. externally inaccessible locking device is working.

Es ruß vorangesetzt werden, daß gemäß den Unfallverhütungsvorschriften ein höherer Arbeitsdruck als 1,5 atü nicht einstellbar sein darf.It must be preceded by soot that according to the accident prevention regulations it must not be possible to set a working pressure higher than 1.5 atü.

Die bekannten Einrichtungen di:eseT Art ließen bei einer Grenzsperre ein Wechseln :außerhalb dieser Sperre nicht zu, ;sie waren also für einen vorbestimmten Wert einer vorgesehenen Belastung e.ingerichtet.The well-known institutions of this type left at a border barrier a change: outside of this lock not to,; they were therefore for a predetermined The value of a planned load is established.

Der Gegenstand der Erfindung bezieh -t .sieh auf eine solche Sperre, bei der innerhalb einer nicht überschTeitbaren Grenze (i,5 atü) je nach den verschiedenen Arbeitsbedingungen die Belastung auf o bis maximal 1,5 atü eingestellt werden kann, ohne daß aber dieGrenzsperrevan außenverstellt wenden kann. Hierbeiwird eine an sich bekannte gekonterte Gewindehilllse verwendet.The subject matter of the invention relates to such a lock, with within a limit that cannot be exceeded (i, 5 atü) depending on the various Working conditions the load can be adjusted to o to a maximum of 1.5 atmospheres, but without the barrier being able to turn externally adjusted. Here is a known countered threaded sleeve used.

Die Erfindung äst in .der Zeichnung veranschaulicht.The invention is illustrated in the drawing.

Nach Einlassen des Azetylengases :in :den Hochdruckraum des Ventils wird - nach Ablesen -des Innken Manometers für den Zustand der Flasche -die Regulierschraube, d. h. :die Schraubspindel i, i", am unteren Ende des Ventilgehäuses 2 verschraubt und drückt debei über eine Kugel .und einen Federeinsatz 3 auf die Feder 6, die am Teller 7 *angreift.' Zwischen diesem und einer Druckplatte 9 ist eine Membran S eingeklemmt. An -der Druckplatte 9 sitzt ein Stift io, der am Ventilkegel angreift.After admitting the acetylene gas: into: the high pressure chamber of the valve - after reading the Innken manometer for the condition of the bottle - the regulating screw, d. H. : the screw spindle i, i ″, screwed to the lower end of the valve housing 2 and presses debei over a ball .und a spring insert 3 on the spring 6, the attacks on plate 7 *. ' Between this and a pressure plate 9 is a membrane S pinched. On the pressure plate 9 there is a pin io which engages the valve cone.

In dem Spindelgehärase 2 -ist ein Gewinde 12 an der Innenwand angeordnet, in dem eine Gewindehülse q. verschraubbar angebracht ist, an der nach entsprechender Einstellung im Grenzfall (i,5 atü) der Einsatz 3 anschlägt. Zu der Sperre gehört noch dieKonter-Gewindehülse 5. Der Einsatz 3 kann sich also vom Gehäuseboden bis zur Sperre 4,5 bewegen und damit alle Werte von o his 45 atü einstellen. Die Spiii:del befindet sich in der Abbildung in Höchstlage.In the spindle housing 2 - a thread 12 is arranged on the inner wall, in which a threaded sleeve q. is screwed attached to the corresponding Setting in borderline cases (i, 5 atü) the insert 3 strikes. Belongs to the lock nor dieKonter threaded sleeve 5. The insert 3 can therefore extend from the housing base to move to lock 4,5 and thus set all values from 0 to 45 atü. The Spiii: del is in the highest position in the illustration.
