This invention discloses a flow regulation control valve for hydrogen-blended natural gas and its operating method, belonging to the field of control valve technology. It includes a valve body with a flow channel inside, and a valve seat fixedly installed inside the flow channel. The valve seat has a flow-diverting mechanism inside, including a valve cover fixedly connected inside the valve seat, a valve core inside the valve cover, and a lifting mechanism above the valve body for controlling the height of the valve core.

The lifting mechanism drives the valve core to achieve first-stage throttling, while the regulating mechanism drives the sealing plate to rotate, controlling lateral flow diversion to achieve second-stage fine regulation. With the two stages working together, the flow area is reduced at small openings to lower the flow velocity and suppress oscillations, while the flow area is increased at large openings to ensure flow rate. This solves the problems of poor regulation accuracy and easy valve core oscillation at high hydrogen blending ratios and small openings, achieving precise flow control and stable operation.
