Description
Auslaßventil für Schmelzkessel Bei der Herstellung von Bleirohren, insbesondere von Bleimänteln für Kabel, gelangen in den Bleimantel Unreinigkeiten, welche zu den bekannten Fehlerstellen führen, die die Widerstandsfähigkeit des Bleimantels gegen Druck schwächen, seine Lebensdauer herabsetzen und ihn sogar von vornherein unbrauchbar machen können. Bei Bleipressien mit Bleischmelzkesseln mit wenig geneigtem Bleiauslauf entstehen die Unreinigkeiten vielfach durch die zur Zeit benutzten Ablaßventile der Bleischmelzkessel, in denen sich nach dem Ablassen des Bleies restliches Blei an den wenig geneigten Stellen sammelt und dort oxydiert. Die Bleioxyde werden beim nächsten Ablassen des geschmolzenen Bleies von dem flüssigen Blei mit fortgespült und gelangen auf diese Weise in den Aufnehmer der Bleipresse und von dort in das Erzeugnis.Outlet valve for melting kettle In the manufacture of lead pipes, especially from lead sheaths for cables, impurities get into the lead sheath, which lead to the known flaws that affect the resistance of the lead jacket weaken against pressure, reduce its service life and even prevent it from the outset can render useless. For lead presses with lead melting kettles with a little inclined Lead leakage, the impurities are often caused by the drain valves currently in use the lead melting kettle, in which the lead remains after the lead has been drained collects in the less inclined places and oxidizes there. The lead oxides are at The next discharge of the molten lead is washed away by the liquid lead and in this way get into the pick-up of the lead press and from there into the Product.
Gemäß der Erfindung wird das Entstehen dieser Unreinigkeiten dadurch verhindert, daß im Ventilgehäuse ein Einsatz mit einer derart schrägen Fläche angeordnet ist, daß das Schmelzgut restlos abfließt.According to the invention, this will cause these impurities to arise prevents an insert with such an inclined surface from being arranged in the valve housing is that the melt flows off completely.
Ein Ausführungsbeispiel der Erfindung ist in der Abbildung schematisch dargestellt. An dem Auslaßstutzen i ist das Auslaßrohr 2 mit Hilfe von Schrauben 3 angeschraubt. Das Ausflußrohr z ist :aus einem Stück mit einem Gewindeteil 4 .hergestellt, in welchem der mit Gewinde und einem Vierkant 5 versehene Ventilkegel 6 geführt ist. Damit sich nicht unter dem Auslaßstutzen i Blei sammeln und dort oxydieren kann, ist in dem oberen Teil des Gewindeteiles q. ein Einsatz 7 angeordnet, durch den der Schaft 8 der Ventilspindel hindurchgeführt ist. Der Einsatz 7 hat eine schräge Fläche g, die so stärk geneigt ist, daß kein Schmelzgut auf ihr zurückbleiben kann, sondern daß das gesammelte Schmelzgut abfließen muß. Zum öffnen und Schließen hat die Ventilspindel einen Vierkant 5, auf welchen ein Hebel, ein Schlüssel, ein Handgriff oder ein Handrad oder sonst dergleichen Antriebsvorrichtung gesteckt werden kann.An embodiment of the invention is shown schematically in the figure shown. The outlet pipe 2 is attached to the outlet connection i by means of screws 3 screwed on. The outlet pipe z is: made of one piece with a threaded part 4. in which the threaded valve cone 6 provided with a square 5 is guided is. So that lead does not collect under the outlet connection and oxidize there can is in the upper part of the threaded part q. an insert 7 arranged by which the shaft 8 of the valve spindle is passed through. The insert 7 is inclined Surface g, which is so steeply inclined that no melt material can remain on it, but that the collected melt must flow away. Has to open and close the valve spindle has a square 5 on which a lever, a key, a handle or a handwheel or other similar drive device can be inserted.
