Description
für den Schnellschluß.for the quick closing.
Die Erfindung betrifft ein Spindelventil, insbesondere für Druckleitungen, das in bekannter Weise mit einer zwischen Spindel und Ventilteller angeordneten lösbaren Kupplung für den schnellen Abschluß versehen ist. Die Erfindung bezweckt, den erforlichen, augenblicklichen Abschluß des Ventils von der Reibung der Ventilspindel an der Stopfbuchse unabhängig zu machen. Dies wird dadurch er-ίο reicht, daß in der hohlen Spindel eine Stange angeordnet ist, die zwischen Kugeln eingeschoben wird, die in bekannter Weise die Spindel mit dem Ventilteller kuppeln.The invention relates to a spindle valve, in particular for pressure lines, which is known in Way with a releasable coupling arranged between the spindle and the valve plate is provided for a quick conclusion. The invention aims to provide the necessary, instantaneous Closure of the valve independent of the friction of the valve spindle on the stuffing box close. This is achieved by a rod in the hollow spindle is arranged, which is inserted between balls, the spindle in a known manner couple with the valve disc.
In der Zeichnung ist ein Beispiel der Erfindung dargestellt, und zwar zeigenIn the drawing, an example of the invention is shown, namely show
Abb. ι einen Längsschnitt eines Durchgangsventils, Fig. Ι a longitudinal section of a through valve,
Abb. 2 die Kupplung in einer anderen Ausführungsform. Fig. 2 the coupling in another embodiment.
ι ist der Ventilteller und 2 die Spindel, die hohl ausgeführt ist. Im Hohlraum der Spindel 2 ist eine Stange 3 angeordnet, welche mit dem verjüngten Ende 4 die Kugeln 5, die z. B. paarweise in einer wagerechten Bohrung der Spindel 2 untergebracht sind, in die Hohlkehle des Ventiltellerhalses hineindrückt.ι is the valve plate and 2 is the spindle, which is made hollow. In the cavity of the spindle 2 a rod 3 is arranged, which with the tapered end 4, the balls 5, the z. B. are housed in pairs in a horizontal bore of the spindle 2, in the groove of the valve plate neck.
In der gezeichneten Lage ist der Ventilteller mit der Spindel verkuppelt und kann durch entsprechende Drehung des Handrades 6 sowohl gehoben als auch gesenkt, das Ventil also geöffnet und geschlossen werden. Zu einem augenblicklichen Abschluß des Ventils ist nur erforderlich, die Stange 3 so weit zu heben, daß sie mit ihrem unteren verjüngten Ende außer Berührung mit den Kugeln kommt. Da diese nur mit einem sehr kleinen Segment in die Hohlkehle des Ventiltellerhalses hineingreifen, so werden sie durch das Eigengewicht des Ventiltellers sofort gegen die Mittelachse der Spindel 2 gedrückt, und der nun durch keine Kraft mehr gehaltene Ventilteller fällt unter dem Einfluß seines Gewichtes und der Saugwirkung des Druckflüssigkeitsstromes sofort auf seinen Sitz im Gehäuse. Um das Ventil wieder öffnen zu können, wird die Spindel durch entgegengesetzte Bewegung des Handrades auf die untere Endlage niedergeschraubt und dann die Stange 3 ebenfalls in die untere Endlage zurückgestoßen. Dadurch ergibt sich dann wieder die in Abb. 1 gezeigte Stellung.In the position shown, the valve plate is coupled to the spindle and can by corresponding rotation of the handwheel 6 both raised and lowered the valve so be opened and closed. To an instantaneous closure of the valve it is only necessary to lift the rod 3 so far that it tapered with its lower End out of contact with the balls. Since this only has a very small segment reach into the groove of the valve plate neck, so they are due to their own weight of the valve disk immediately pressed against the central axis of the spindle 2, and the now through No more force held valve head falls under the influence of its weight and the Suction effect of the hydraulic fluid flow immediately on its seat in the housing. To be able to open the valve again, the spindle is moved to the lower end position by moving the handwheel in the opposite direction screwed down and then the rod 3 also pushed back into the lower end position. This then results in the position shown in Fig. 1 again.
Die Ausführungsform nach Abb. 2 unterscheidet sich von der ersten nur durch die Ausbildung der Verjüngung 4 der Stange 3, welche etwas oberhalb des unteren Endes angeordnet ist. Infolgedessen erfolgt die Kupplung der Spindel 2 mit dem Ventilteller 1 umgekehrt durch Heben und die Entkupplung durch Senken der Stange 3.The embodiment according to Fig. 2 differs from the first only by the Formation of the taper 4 of the rod 3, which is arranged slightly above the lower end is. As a result, the spindle 2 is coupled to the valve disk 1 vice versa by lifting and uncoupling by lowering the rod 3.
Bei den dargestellten Beispielen wird die Kupplung von außerhalb des Druckraumes her gelößt und eingerückt. Die Erfindung umfaßt aber auch die Fälle, in denen die eine oder andere "Art, oder beide zusammen, die Kupplung einzurücken auch von anderer Stelle aus, z. B. von innen, wie es beim Eintreten von Rohrbrüchen notwendig ist, erfolgen kann. In diesem Falle wird die Stange 3 durch den Ventilteller hindurch nach unten so weit verlängert, daß er in den Wirkungskreis eines Kolbens kommt, der in einem im Abschlußraum angeordneten Zylinder bei plötzlicher Druckänderung infolge von Rohrbrüchen sich bewegt und an die Stange stößt, die dann die Entkupplung einleitet.In the examples shown, the clutch is operated from outside the pressure chamber released and indented. The invention also includes the cases in which the one or another "way, or both together, the clutch can also be engaged from another point off, e.g. B. from the inside, as is necessary when pipe bursts occur, can be done. In this case, the rod 3 is extended downward through the valve disk so far, that he comes into the sphere of action of a piston, which in a cylinder arranged in the closing chamber when suddenly Pressure change due to pipe ruptures moves and hits the rod, which then initiates decoupling.
