    摘要： The inner, gate rotating shaft of a pair of concentric shafts on a driving side of a spherical valve housing rotates a valve gate freely supported for rotation on the same side by the outer, translation shaft of the pair and on the driven side by a single translation shaft. Both translation shafts have an eccentric portion about which the gate valve rotates. An arcuate torsion beam is mechanically coupled at its ends to the two translation shafts and lies to the side of the spherical valve housing opposite that of the gate. By selectively locking the gate rotating lever and driving the gate translation lever or vice versa, the spherical gate is rotated freely about the stationary translation shafts to and from a position outside of the flow path and at right angles thereto or axially cammed into contact with a coaxial valve seat by rotation of both translation shafts. A plurality of overcenter locking clamps couple abutting ends of two such valves to effect a double seal, quick disconnect for a fluid line which couples or disconnects without axial movement.
