Abstract

The utility model relates to the technical field of control valves, in particular to an automatic control multi-stage adjustable duplex V-shaped hemisphere adjusting ball valve, which comprises a valve body component (1), a valve seat component (3), a valve rod component (4), a lengthened valve cover component (6), a transmission component (7), a rack transmission position adjusting mechanism (8) and a power mechanism (9). The valve rod assembly (4) is arranged on the valve body assembly (1), and the transmission assembly (7) drives the valve rod assembly (4) to rotate under the action of the rack transmission position adjusting mechanism (8) and the power mechanism (9) so that the valve body assembly (1) can be opened or closed. The ball valve has the advantages of being compact in structure, light in weight, high in adjusting precision, high in sealing performance and capable of achieving automatic control, meanwhile, a multi-stage flow adjusting mode is achieved, and accurate flow control can be achieved under various severe working conditions.
