Description

  

      Auslaufventil    ohne     Stopfbüchse.       Vorliegende Erfindung bezieht sich auf  ein Auslaufventil ohne Stopfbüchse mit  kolbenartig ausgebildetem, geführtem Ventil  körper und einem     Sickerwasserraum        imVentil-          gehäuse,    aus. dem das     Sickerwasser    durch ein  im Innern des Ventils vorgesehenes Absauge  röhrchen abgeführt wird.

   Zahlreiche Bau  arten solcher Auslaufventile sind bekannt;  da jedoch die     Absaugewirkung    des Röhr  chens ungenügend war, konnten sie sich nicht       eint'     Bei der vorliegenden Erfindung wird eine  gute Saugwirkung des an den     Sickerraum     angeschlossenen und zum Beispiel im Aus  laufraum des Ventils ausmündenden Röhr  chens dadurch erzielt, dass es vor seinem  Ende mit seitlichen     C)ffnungen    versehen ist,  durch welche Wasser in Glas     Innere    des  Röhrchens eintreten und dort eine     Ejektor-          wirkung    hervorrufen kann, durch die die  Saugkraft des Röhrchens bedeutend erhöht  und so jeder Austritt von Wasser an der  Spindel verhütet wird.

    



  Auf der Zeichnung ist ein     Ausführungs-          beispiel    des Erfindungsgegenstandes darge  stellt.    In dem Ventilgehäuse 1 ist der kolben  artig ausgebildete, geführte Ventilkörper 2  angeordnet, der in bekannter Weise durch  eine mit Gewinde versehene Spindel 3 be  wegt wird. Das Gewinde der Spindel 3 ist  in einem entsprechenden Muttergewinde des  Oberteils 4 gelagert, das am Ventilgehäuse 1.  verschraubt ist. Die Ventildichtung ist mit  5, das     Zuflussloch    mit 6 und der Ventilsitz  mit 7 bezeichnet.  



  An den     Sickerwasserraum    8     ist    das Ab  saugerohr 9 angeschlossen, das mit seinem  freien Ende im Auslaufraum des Ventils  ausmündet. Zur Erzielung einer guten Saug  wirkung, die für derartige Ventile Bedingung  ist, ist das Rohr 9 vor seinem Ende mit     Öff-          nungen    10 versehen, durch die Wasser in  das Innere des Röhrchens 9 hineintritt und  nach Art eines     Ejektors    auf das Sickerwas  ser eine Saugwirkung ausübt. Es wird da  durch nicht bloss das an der Kolbenführung  durchsickernde Wasser abgeführt, sondern  noch Aussenluft von der     Spindelseite    her ein  gesaugt, so dass jedes Austreten von Wasser  an der Spindel     ausgeschlossen    ist.

   Bei Durch  führung des Röhrchens bis an das Ventil-      ende wird das freie Ende des Rohres 9  gegenüber dem Ventil zweckmässig     durcb     Rippen 11, die als herumlaufendes, gewell  tes und federndes Blechband ausgebildet sein  können, gesichert. Die Rippen dienen gleich  zeitig in bekannter Weise als     Strahlregler.  



      Outlet valve without stuffing box. The present invention relates to an outlet valve without a stuffing box with a piston-like, guided valve body and a seepage water space in the valve housing. which the seepage water is discharged through a suction tube provided inside the valve.

   Numerous types of construction of such outlet valves are known; However, since the suction effect of the Röhr chens was insufficient, they could not unite. In the present invention, a good suction effect of the Röhr chens connected to the seepage chamber and, for example, in the outlet chamber of the valve is achieved by having it in front of its end with lateral C) openings are provided through which water can enter the glass inside the tube and cause an ejector effect there, through which the suction force of the tube is significantly increased and thus any leakage of water at the spindle is prevented.

    



  An exemplary embodiment of the subject matter of the invention is shown in the drawing. In the valve housing 1 of the piston-like, guided valve body 2 is arranged, which is moved in a known manner by a threaded spindle 3 be. The thread of the spindle 3 is mounted in a corresponding nut thread of the upper part 4, which is screwed to the valve housing 1. The valve seal is denoted by 5, the inflow hole by 6 and the valve seat by 7.



  From the suction pipe 9 is connected to the seepage water space 8, which opens with its free end in the outlet space of the valve. To achieve a good suction effect, which is a condition for such valves, the pipe 9 is provided with openings 10 in front of its end, through which water enters the interior of the pipe 9 and exerts a suction effect on the seepage water in the manner of an ejector . Not only is the water seeping through on the piston guide removed, but outside air is also sucked in from the spindle side, so that any leakage of water at the spindle is excluded.

   When the tube is guided through to the valve end, the free end of the tube 9 is suitably secured with respect to the valve by ribs 11, which can be designed as a corrugated and resilient sheet metal strip running around. The ribs also serve as a jet regulator in a known manner.
