Description
Den Gegenstand der Erfindung bildet ein Absperrventil, welches in eingebautem Zustand
in einfacher Weise sich wirksam einschleifen und dichten läßt. Dies ist ein Vorzug,
der besonders da in Erscheinung tritt, wo es sich um häufig bediente Ventile handelt,
durch die dicke oder verschmutzte Flüssigkeiten fließen, beispielsweise bei Dampfkesselabschlämmventilen,
ίο Die Wirkungsweise ist folgende:The subject of the invention is a shut-off valve which, when installed, can be effectively ground in and sealed in a simple manner. This is a benefit that is particularly evident where there are frequently operated valves through which thick or dirty liquids flow, for example steam boiler drain valves,
ίο The mode of action is as follows:
Die Ventilspindel α ist bei b in an sich bekannter Weise geteilt und durch die Kupplung c zusammengehalten. Beim öffnen und Schließen des Ventils mittels des Handrades d dreht sich also nur ,der obere Teil der Spindel h, während der untere Teil mit dem Ventilteller e sich nur hebt bzw. senkt.The valve spindle α is divided at b in a manner known per se and held together by the coupling c . When the valve is opened and closed by means of the handwheel d , only the upper part of the spindle h rotates, while the lower part with the valve disc e only rises or falls.
Am Ventilteller e ist die Dichtungsringfläche g zur Dichtungsfläche / des Ventilsitzes exzentrisch angeordnet.On the valve disk e , the sealing ring surface g is arranged eccentrically to the sealing surface / the valve seat.
Wenn nun mittels eines Schraubenschlüssels, der am Sechskant h der unteren Spindel σ angreift, die Spindel bei geschlossenem Ventil gedreht wir.d, dann wird die Dichtungsringes flächeg auf Dichtungsfläche/ eine drehendeIf the spindle is now rotated with the valve closed by means of a wrench that engages the hexagon h of the lower spindle σ, then the sealing ring surface g is turned on the sealing surface / a rotating one

und infolge ihrer Exzentrizität auch schabende Bewegung ausführen, wodurch alle Fremdkörper, wie Kesselstein, Schlamm usw., zerrieben und entfernt werden.and as a result of their eccentricity they also carry out a scraping motion, whereby all of them Foreign matter such as scale, sludge, etc., is crushed and removed.
In Abb. 2 ist die Dichtungsringfläche g kreisförmig und exzentrisch zur Dichtungsfläche / dargestellt. Auch mit einer Dichtungsfläche ovaler, wellenförmiger oder eckiger Form kann die schabende Wirkung beim Einschleifen erzielt werden.In Fig. 2, the sealing ring surface g is shown circular and eccentric to the sealing surface /. The scraping effect when grinding in can also be achieved with a sealing surface of oval, wavy or angular shape.
