Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung besteht in der eigenartigen Befestigungsweise des Ventilsitzes bei Absperrventilen, welche eine leichte und bequeme Entfernung desselben bei vollständig zuverlässiger Befestigung gestattet.The invention consists in the peculiar way of fastening the valve seat in shut-off valves, which an easy and convenient removal of the same while being completely reliable Attachment permitted.

Auf der Zeichnung ist ein gemäfs der Erfindung eingerichtetes Absperrventil im Verticalschnitt veranschaulicht. .In the drawing, a shut-off valve set up according to the invention is in vertical section illustrated. .

A ist der Ventilteller, welcher mittels der Spindel B mit Gewinde b und des Handgriffes oder Handrades c in gewöhnlicher Weise geöffnet und geschlossen werden kann. Der Ventilteller A schliefst gegen die obere ringförmige Fläche des Ventilsitzes F und ist mit einem nach unten abnehmenden konischen Ring D versehen, während die Flügel E zum Führen des Ventils dienen. A is the valve disk, which can be opened and closed in the usual way by means of the spindle B with thread b and the handle or handwheel c. The valve disk A closes against the upper annular surface of the valve seat F and is provided with a conical ring D which decreases downwards, while the vanes E serve to guide the valve.

Der Zweck des konischen Ringes D ist, das allmähliche Eintreten des Dampfes u. s. w. zu bedingen, indem durch Heben des Ventiltellers, gleichgiltig wie schnell dies erfolgen möge, der Durchtritt des Dampfes nur allmählich geschehen kann und so das Ventilgehäuse vor Stöfsen schont.The purpose of the conical ring D is to allow the steam to gradually enter and so on by lifting the valve disc, no matter how fast this may take place, the passage of the steam can only happen gradually and so the valve housing in front Stöfsen is gentle.

Die Befestigung des Ventilsitzes geschieht in der Weise, dafs man in dem Ventilgehäuse über dem Sitz Ansätze H formt, gegen welche die in den äufseren Ansätzen bezw. Oehren des Sitzes F verstellbaren Schrauben G angezogen werden und somit den Sitz fest in seiner Stellung halten. Diese Befestigung bietet bei der behufs Reinigung nöthigen Entfernung des Ventilsitzes den ganz besonderen Vortheil, dafs sich die Schrauben G nach deren Lösung unten gegen das Gehäuse anlegen und den Sitz, der nach längerem Gebrauch sich in dem Gehäuse festklemmt, auf diese Weise herausheben. Nach erfolgtem Lösen des Sitzes dreht man denselben, um die Schrauben G aufser Eingriff mit den Ansätzen H zu bringen, und hebt dann den Ring heraus.The fastening of the valve seat is done in such a way that approaches H are formed in the valve housing above the seat, against which the or in the outer approaches. Ears of the seat F adjustable screws G are tightened and thus hold the seat firmly in its position. This fastening offers the very special advantage when removing the valve seat for the purpose of cleaning, that the screws G, after they have been loosened, lie against the bottom of the housing and in this way lift out the seat, which is clamped in the housing after prolonged use. After loosening the seat, turn it to bring the screws G out of engagement with the lugs H , and then lift out the ring.
