Description

  

  Zusatzpatent zum     Hauptpatent    Nr. 337697    Absperrorgan    Vorliegende Erfindung     betrifft    eine Verbesserung  des im Hauptpatent beschriebenen Absperrorgans,  wobei die Schmierschicht ersetzt wird durch eine  Hülse aus Kunststoff.  



  Die Verbesserung besteht darin, dass zur Er  höhung der     Druckbeständigkeit    der Kunststoffhülse  noch weitere     Werkstoffe    in Betracht gezogen werden.  



  In der Beschreibung zum Hauptpatent ist er  wähnt, dass es für gewisse     Kunststoffmaterialien     nötig sein wird, eine     Armierung    von z. B. Blech,  Draht, Gewebe, Asbestfasern, Glasfasern usw. ein  zubauen.  



  Versuche haben erwiesen, dass eine     Armierung     des Kunststoffes für Hähne bei hohem     Druck    vor  teilhaft angewendet wird.  



  Dabei haben sich Graphit und Kohle als Füll  material für die Kunststoffhülse bewährt.



  Additional patent to the main patent no. 337697 shut-off device The present invention relates to an improvement of the shut-off device described in the main patent, wherein the lubricating layer is replaced by a sleeve made of plastic.



  The improvement consists in the fact that other materials are also taken into account in order to increase the pressure resistance of the plastic sleeve.



  In the description of the main patent it is mentioned that it will be necessary for certain plastic materials to reinforce z. B. sheet metal, wire, fabric, asbestos fibers, glass fibers, etc. to build.



  Tests have shown that a reinforcement of the plastic for taps at high pressure is used before geous.



  Graphite and carbon have proven to be useful as filling material for the plastic sleeve.
