TAPER KEY JOINT FOR CONNECTING A ROTARY VALVE SHAFT TO A VALVE DISC |
摘要 |
An improved joint connection between a rotary valve shaft (12) and valve closure member (10) for a fluid valve. A tapered key (24) has a flat surface (26) tapered at a small angle with respect to the opposite key surface. The rotary valve shaft (12) includes a groove (32) with a flat surface. The tapered key (24) is wedged into a passageway in the valve closure member to form an interference fit between the closure member (10), key (24) and shaft (12). |
