The invention relates to the technical field of ball valves, in particular to a hydraulic drive ball valve which comprises a sealing module, a pressurizing module and a pressurizing module, and the sealing module comprises a hydraulic ball valve connected with the sealing module and two channels connected with the hydraulic ball valve in an inserted mode. According to the device, synthetic rubber is conveyed into a melting hopper, after the synthetic rubber becomes liquid, an electromagnetic valve is turned on, the liquid enters an annular cooling cavity along a conveying pipe, then a double-shaft motor is turned on, the double-shaft motor enables a piston rod to move through a gear, the piston rod presses air in an air inlet pipe into an annular liquid accumulation cavity, and then the liquid enters the annular cooling cavity; liquid is cooled to form a sealing ring, then the sealing ring is continuously inserted into a piston rod of the air inlet pipe, so that the internal pressure of the annular liquid acc
