  Verfahren zum Abdichten der   Rückschlagventile   von   Drucitmittelbehältern.   



   Die Erfindung betrifft ein Verfahren zum Abdichten von von innen her durch Rückschlagventile verschlossenen Druckmittelbehältern. Das Veifahren besteht darin, dass der   Verschlusskölper   von innen her durch bedeutende Erhöhung des Innendruckes mittels   Erwärmung so fest auf seinen Sitz gepresstwird,   dass eine einer homogenen Verbindung   gleichkommende Anlagerung   der gepressten und hiedurch dauernd veränderten Stellen stattfindet. 



   Die Zeichnung veranschaulichtin Fig. 1 teilweise im Schnitt eine   Ausführungsform   eines zur Durchführung des Verfahrens geeigneten Druckmittelbehälters. Fig. 2 zeigt einen solchen   Druckmittelbehälter   in einem Gefäss mit heisser Flüssigkeit liegend. 



   In Fig. 1 ist a der z. B. mit flüssiger Kohlensäure gefüllte, mittels des Kugelventil k abgedichtete Druckmittelbehälter. Wird ein solcher Behälter in das heisse Flüssigkeit enthaltende Gefäss eingelegt, so wird sein Innendruck durch die Erwärmung auf mehrere hundert Atmosphären gesteigert und die   Verschlusskugel   7c um eine gewisse Strecke tiefer in ihren z. B. konischen Sitz gepresst, wodurch dann die beabsichtigte, einer homogenen Verbindung gleichkommende Anlagerung der gepressten Stellen stattfindet.

   Ob das   erforderliche Mass   des Anpressungsdruckes bei der Ausführung des Verfahrens erreicht mithin das Ventil um das zur Erreichung der homogenen Anlagelung notwendige Stück tiefer in seinen Sitz hineingepresst worden ist, lässt sich mittels eines in die Mündung des Druckmittelbehälters bis an das Ventil heran eingeführten Stichmasses feststellen.

  Method for sealing the check valves of pressure medium containers.



   The invention relates to a method for sealing pressure medium containers closed from the inside by check valves. The process consists in that the sealing body is pressed so tightly onto its seat from the inside by means of a significant increase in the internal pressure by means of heating that the pressed and thus permanently changed areas are deposited, which is equivalent to a homogeneous connection.



   The drawing illustrates in FIG. 1, partially in section, an embodiment of a pressure medium container suitable for carrying out the method. Fig. 2 shows such a pressure medium container lying in a vessel with hot liquid.



   In Fig. 1, a is the z. B. filled with liquid carbon dioxide, sealed by means of the ball valve k pressure medium container. If such a container is placed in the hot liquid-containing vessel, its internal pressure is increased by the heating to several hundred atmospheres and the locking ball 7c is a certain distance deeper in its z. B. pressed conical seat, which then takes place the intended, a homogeneous connection equivalent to accumulation of the pressed points.

   Whether the required amount of contact pressure is reached when the method is carried out, the valve has been pressed deeper into its seat by the amount necessary to achieve homogeneous contact, can be determined by means of a gauge introduced into the mouth of the pressure medium container up to the valve.



   Instead of the ball, another closure body, e.g. B. a valve cone, use. The spring t drawn in the container a, which acts on the ball by means of a funnel t,

  This is unnecessary when using a leaded valve body.



     PATENT CLAIMS:
1. A method for sealing the non-return valves of pressure medium containers, characterized in that the valve body is pressed so tightly onto its seat from the inside by increasing the internal pressure by means of heating that a homogeneous connection occurs between the pressed and constantly changing places.
