Device for clamping a rotatable reaction vessel

摘要

The device according to the invention essentially comprises two concentrically arranged tubes, the one (2) serving as a rotatable gas supply and the other (1), as the reaction tube, being exposed to high temperatures and having to be replaced from time to time. To this end, the large union nut (12) is provided which, via the springs 3 and a few intermediate elements, provides the force necessary for the sealing effect of the O-rings (8) and (28). <IMAGE>
