  Niederschraubventil für hochgespannten Sauerstoff. 



   Bei den Niederschraubventilen, die z. B. an Behältern für hochgespannten Sauerstoff angebracht sind, ist im   Ventilkörper eine   kleine Dichtung eingelegt, die von einem Hart-   gummipiättchen gebildet   wird. Es hat sich nun gezeigt, dass dieses Ilartgummiplättehen die 
 EMI1.1 
 Absperrung von Gasen handelt, die die Entzündung befordern oder begünstigen. 



   Um diesen Übelstand zu verhindern, wird nach der Erfindung für diese Dichtungplatte ein Material verwendet, das nicht die hohe Entzündbarkeit des Hartgummi. wohl aber die zur Erzielung einer guten und sicheren Abdichtung erforderliche Elastizität besitzt, niimlich Elfenbein. Eine daraus gefertigte Dichtungsscheihe kann nicht nur wegen ihrer geringen Brennbarkeit nicht zur   Entzündung gebracht   werden, sondern die Gefahr wird schon dadurch eine geringere, dass Elfenbein die Wärme schneller ableitet und   mithin   nicht in   dem Masse   in sich aufspeichern kann, wie es bei dem sehr schlechten Wärmeleiter   Hartgummi   der Fall ist. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Screw-down valve for high-pressure oxygen.



   In the screw-down valves that z. B. are attached to containers for high-tension oxygen, a small seal is inserted in the valve body, which is formed by a hard rubber plate. It has now been shown that this Ilartgummeplättehen the
 EMI1.1
 Shutting off gases that promote or promote ignition.



   In order to prevent this inconvenience, according to the invention, a material is used for this sealing plate which does not have the high flammability of hard rubber. but has the elasticity required to achieve a good and secure seal, namely ivory. A sealing sheet made from it cannot ignite only because of its low flammability, but the risk is reduced because ivory dissipates heat more quickly and therefore cannot store it in the same mass as the very poor heat conductor Hard rubber is the case.
