Abstract
The invention discloses a high-pressure large-caliber duplex ball valve belonging to the valve field. The high-pressure large-caliber duplex ball valve comprises a high-pressure large-caliber ball valve and a second high-pressure large-caliber ball valve, wherein fluid center lines of balls of the two valves are consistent. Such a valve has the effects of replacing upstream sealing high-pressure ball valves having effects of four single pistons or replacing high-pressure ball valves having effects of two double pistons. When the valve is installed on a pipeline and the pipeline is to be cut off, the cutoff of the pipeline can be completed by simply rotating one ball, and the other ball can not be operated until a valve base seal assembly of the ball fails. Also, the two balls can be alternately operated, so that the valve can have longer service life, achieve the function of at least two high-pressure large-caliber ball valves and achieve the effects of double insurance and double cutoff for pipeline use. Since the two high-pressure ball valves are integrally molded, temporary regulation of the flow center lines of the two ball valves in the installing process is unnecessary, and a connection point and a leakage point in the direct serial installation of the two high-pressure ball valves are also reduced, thereby ensuring safety and reliability.
