Description

Vorrichtung zur gegenseitigen Sperrung von Rohrabsperrvorrichtungen Die Erfindung betrifft eine Vorrichtung zur gegenseitigen Sperrung von Rohrabsperrvorrichtungen mit steigenden Spindeln und an ihnen steigenden Zeigern und besteht in einer senkrecht zu den Spindelachsen und in ihrer Ebene verschiebbaren Verriegelungsplatte mit L-förmigen Schlitzen, in welchen sich die Sperrstifte bewegen.Device for the mutual blocking of pipe shut-off devices The invention relates to a device for the mutual locking of pipe shut-off devices with rising spindles and on them rising pointers and consists in a vertical to the spindle axes and in their plane displaceable locking plate with L-shaped Slots in which the locking pins move.

Im Dampfbetrieb ist es manchmal not-,vendig, einzelne Rohrabsperrungen gegen unbefugtes öffnen zu sichern, solange eine .audere Absperrung geöffnet ist, und umgekehrt. Da solche Absperrungen gewöhnlich an einer gemeinsamen Abz-,veigstelle liegen, sind sie räumlich benachbart, so daß eine einfache mechanische Verriegelung möglich ist. Ferner kann bei benachbarten Absperrorganen eine Sperrung auch dadurch erreicht werden, daß das Handrad des einen Absperrorgans die Betätigung .des anderen Absperrorgans in gewissen Stellungen verhindern. Es ist aber auch möglich, entfernter liegende Vorrichtungen mittels Fernantriebes zu betreiben und die Antriebe nebeneinanderzusetzen.In steam operation it is sometimes necessary, individual pipe shut-offs secure against unauthorized opening as long as another barrier is open, and vice versa. Since such barriers are usually at a common disconnection point lie, they are spatially adjacent, so that a simple mechanical lock is possible. Furthermore, a blockage can also be achieved in the case of adjacent shut-off devices be achieved that the handwheel of one shut-off device actuates the other Prevent shut-off device in certain positions. But it is also possible more distant to operate horizontal devices by means of remote drive and to place the drives next to each other.

In .der Zeichnung ist die erfindungsgemäße Vorrichtung an solchen Fernantrieben .dargestellt; sie kann jedoch auch bei. benachbarten Absperrorganen ebensogut angewendet werden.In .der drawing the device according to the invention is such Remote drives .shown; however, it can also be used at. neighboring shut-off devices can be used just as well.

Von zwei nicht dargestellten Rohrabsperrvorrichtungen sind die verlängerten Spindeln i, 2 mittels Rädergetriebes 3, q. an die Antriebsspindeln 5, 6 der überfiursäulen 7, 8 angeschlossen. Mit Hilfe .der Handräder 9, io werden die Spindeln angetrieben. . Die Antriebsspindeln 5, 6 sind in bek annter Weise mit Schraubengewinde versehen und schleppen die Zeiger i i, 12, welche sich in den achsparallelen Schlitzen 13, 14 der überflursäulen 7, 8 bewegen. Die Zeiger greifen in die L-förmnigen Schlitze 15, 16 der Verriegelungsplatte 17 ein. Dabei sind diese L-förmigen Schlitze im dargestellten Falle so angeordnet, daß jeweils nur ein Zeiger sich lotrecht bewegen kann, wenn die Platte 17 in ihren an den Säulen 7, 8 befindlichen Führungen 18, i9 in die Endlage geschoben wird. Die Verriegelungsplatte ist nur waagerecht verschiebbar und durch die Führungen 18, i 9 gegen Hochschieben gesichert. Auf der Platte 17 sind neben den lotrechten Schlitzen Zeigermarken vorgesehen, aus denen das öffnungsverhältnis der Absperrorgane zu ersehen ist.Of two pipe shut-off devices, not shown, the extended spindles i, 2 by means of gear trains 3, q. connected to the drive spindles 5, 6 of the overfiursäulen 7, 8. The spindles are driven with the aid of the handwheels 9, io. . The drive spindles 5, 6 are provided with screw threads in a well-known manner and drag the pointers ii, 12, which move in the axially parallel slots 13, 14 of the above-ground columns 7, 8. The pointers engage in the L-shaped slots 1 5, 1 6 of the locking plate 17 . In this case, these L-shaped slots are arranged in the illustrated case, so that in each case only a pointer can move vertically, if the plate 1 7 in their on the columns 7, 8 located guides 18, is pushed into the end position i9. The locking plate can only be moved horizontally and is secured against being pushed up by the guides 18, i 9. On the plate 17, next to the vertical slots, pointer marks are provided, from which the opening ratio of the shut-off devices can be seen.

In der Zeichnung sind die L-förmigen Schlitze symmetrisch zueinander angeordnet. Sollren dagegen die Antriebe zugleich gesperrt oder frei werden, so müssen die L-förmigen Schlitze gleichgerichtet sein.In the drawing, the L-shaped slots are symmetrical to each other arranged. If, on the other hand, the drives are to be blocked or released at the same time, see above the L-shaped slots must be aligned.
