Den Gegenstand der Erfindung bildet eine. Vorrichtung zum Herausdrücken von Ventilsitzen u. dgl. mit Hilfe einer Schraube, die sich von bekannten ähnlichen Zwecken dienenden Vorrichtungen durch die besondere Bauart der zum Erfassen des Sitzes dienenden Einrichtung kennzeichnet.The subject of the invention is a. Device for pushing out valve seats and the like with the aid of a screw which serve known similar purposes Identifies devices by the special design of the device used to detect the seat.
Auf der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigt The subject of the invention is shown in the drawing, namely shows
ίο Fig. ι die Vorrichtung beim Herausdrücken des Ventilsitzes undίο Fig. ι the device when pushing out of the valve seat and
Fig. 2 die zum Herausdrücken dienende Schraubenspindel mit den an ihr sitzenden Teilen im Querschnitt.2 shows the screw spindle which is used for pushing out and which is seated on it Split in cross section.
Das Gestell α wird auf den oberen Flansch des Ventiles durch Schrauben o. dgl. befestigt und bietet der auf der Schraubenspindel sitzenden Mutter b, die mit zwei Handhaben ausgestaltet ist, eine Unterlage. Die Schraubenspindel c wird von einer Hülse d umfaßt, welche am oberen Teil als Mutter ausgebildet ist. Die zum Erfassen des Ventilsitzes o. dgl. dienenden Klauen e sind an einem am Ende der Schraubenspindel sitzenden Ringe f gelagert, der von zwei Ringen g und h gehalten wird. Die Einstellung der Drückklauen erfolgt durch Drehen der Hülse d, indem die von einem an ihrem Ende sitzenden drehbaren Ringe gehaltenen Streben i, die mit ihnen gelenkig verbundenen Klauen mehr oder weniger weit auseinander spreizen. Soll ein Ventilsitz herausgedrückt werden, so sind die Druckklauen durch die Hülse d so einzustellen, daß diese durch die Bohrung des Sitzes gesteckt werden können. Sodann wird, die Hülse d etwas nach unten geschraubt, wodurch die Klauen e sich schräger stellen und den Ventilsitz von unten erfassen und herausdrücken, wenn die Mutter b gedreht wird.The frame α is fastened to the upper flange of the valve by screws or the like and provides a base for the nut b, which is seated on the screw spindle and is designed with two handles. The screw spindle c is encompassed by a sleeve d , which is designed as a nut on the upper part. The claws e used to grasp the valve seat or the like are mounted on a ring f seated at the end of the screw spindle and held by two rings g and h. The setting of the pressing claws takes place by turning the sleeve d, in that the struts i, which are held by a rotatable ring seated at their end, spread the claws articulated to them more or less far apart. If a valve seat is to be pushed out, the pressure claws are to be adjusted by the sleeve d so that they can be inserted through the bore of the seat. Then the sleeve d is screwed down a little, whereby the claws e are inclined and grasp the valve seat from below and push it out when the nut b is rotated.
