| 摘要 |
The invention concerns an energy recovery control valve (1), comprising a valve body (3) and a rotating plug (5) contained in the valve body. In the valve (1), a through duct (7) is arranged suitable for allowing a fluid to be controlled, to pass through the same valve (1). In the rotating plug (5) a movable passage is provided through which the fluid to be controlled can pass through the rotating plug. The valve (1) comprises a transmission system (9) in turn comprising a mechanical power take-off (11) accessible from outside the control valve itself. A rotor (13) is housed in the movable passage (50) arranged for being driven by the fluid to be controlled and in turn for driving the transmission system (9), which is arranged for transmitting the mechanical energy of the fluid to be controlled, transferred to the rotor (13), outside the control valve through the mechanical power take-off (11). |
