| description | The invention relates to a ball valve, in particular to an energy-saving eccentric semi-ball valve, which comprises a valve body. An eccentric valve shaft is arranged in the valve body and is provided with a sealing ball crown. The energy-saving eccentric semi-ball valve is characterized by also comprising an adjustable valve seat matched with the sealing ball crown, wherein the valve seat is arranged on the inner side of the side wall of a medium outlet of the valve body; the side wall of the medium outlet of the valve body and the corresponding peripheral part of the valve seat are provided with two groups of screws, one group of screws pass through through holes on the side wall of the valve body and are in threaded connection with screw holes on the end face of the valve seat, and the other group of screws pass through screw holes on the side wall of the valve body and the front ends of the crews are used for pressing against the end face of the valve seat; the two groups of screws are arranged at interva |
