Das dargestellte Absperrventil soll stets dicht bleiben, ohne peinlich genau gearbeitet zu sein. Es gestattet, selbst sehr hohen Druck vollständig abzusperren und bei etwaigem Undichtwerden nur durch verstärktes Andrehen der Spindel wieder die völlige Dichtung herbeizuführen, sowie zufällig beschädigte Theile in kurzer Zeit durch neue zu ersetzen.The shut-off valve shown should always remain tight, without being meticulously worked. It allows even very high pressure to be shut off completely and in the event of a leak to bring about complete sealing again only by turning the spindle more intensely, as well as replacing accidentally damaged parts with new ones in a short time.

Fig. ι zeigt ein geschlossenes Absperrventil, an welchem Zc1 der kegelförmig ausgedrehte,, zur Aufnahme des Kegels k dienende, aus hartem Stoff hergestellte Ventilsitz ist. Der aus weichem Stoff, ζ. Β. Kupfer, gefertigte, mit scharfen Rippen versehene Mantel m umschliefst den Kegelkörper Ic und wird .mittelst der Schraube s festgehalten. Die Uebermutter u dient dazu, den Kegel k auf der Spindel g drehbar festzuhalten, und ist mit einem eingedrehten, mit scharfen Rippen versehenen Dichtungsring d ausgerüstet. In Fig. 3 a bis 3 c ist ein für Flachdruck bestimmter, mittelst Stifte t an der Spindel g- drehbar befestigter Körper k dargestellt, an welchem mittelst, der Ringe r und I ein mit mehreren scharfen Rippen t versehener Dichtungsring d befestigt ist, dazu bestimmt, durch Aufdrücken auf ebene Flächen , einen dichten Abschlufs zu erzielen.Fig. 1 shows a closed shut-off valve, on which Zc 1 is the conically twisted, for receiving the cone k serving, made of hard material valve seat. The one made of soft fabric, ζ. Β. Copper, manufactured jacket m provided with sharp ribs surrounds the cone body Ic and is held in place by means of the screw s . The nut u serves to hold the cone k rotatably on the spindle g and is equipped with a screwed-in sealing ring d provided with sharp ribs. In Fig. 3 a to 3 c intended for planographic printing, by means of pins t rotatably attached to the spindle g body k is shown, to which means of the rings r and I a sealing ring d provided with several sharp ribs t is attached, in addition determined to achieve a tight seal by pressing on flat surfaces.

Durch das mittelst der Spindel g bewirkte Eindrücken des Kegels k in den hohlkegelförmigen Sitz Zc1 legen sich die scharfen Kanten der Rippen i des Mantels ni fest an die sie umschliefsende Wand und bewirken dadurch .-den. dichten Abschlufs. Wenn durch mitgerissenen Schmutz oder harte Körperchen eine der Rippen beschädigt wird, so bewirken die anderen Rippen immer noch den dichten Schlufs. Beim Offenhalten des Ventils wird durch festes Anlegen des Dichtungsringes d an den Deckel ein Entweichen der Flüssigkeit durch die Stopfbüchse verhindert und ein Verpacken der Spindel während des Durchflusses durch das Ventil ermöglicht. '■ As a result of the cone k being pressed into the hollow cone- shaped seat Zc 1 by means of the spindle g , the sharp edges of the ribs i of the shell ni lay firmly on the wall surrounding them and thereby cause the. tight closure. If one of the ribs is damaged by entrained dirt or hard bodies, the other ribs still produce the tight seal. When the valve is kept open, the sealing ring d is firmly attached to the cover to prevent the liquid from escaping through the stuffing box and to allow the spindle to be packed while it is flowing through the valve.
