Smoke flue regulating and shutoff valve is coupled to drive shaft by flush-joinable plates allowing blade removal and framework collapse for manageable transport.

摘要

The couplings (7,8) joining blades (2) to the drive shafts (3) allow all the blades to be removed and the frame of the housing to be broken down into frame parts (1.1) for transport. The drive shafts and their actuator linkage (5) remain on their respective frame part for transport and are designed as plug-in shafts to fit into entering points on the blade in question. The couplings consist of a plate (7) nonrotatably fixed to the shaft and a second plate (8) nonrotatably fixed to the blade (2) so the plates fit flush to one another when the blades are installed and are (7,8) fixed together by fasteners, specifically pin and/or screw.
