Efficient plug valve for petroleum drilling

Abstract

The invention relates to the technical field of plug valves, in particular to an efficient plug valve for petroleum drilling, which comprises a fixed seat, the fixed seat is positioned at the bottom end of the whole device, a valve body is mounted at the upper end of the fixed seat, a valve core is mounted in the valve body, an adjusting assembly is mounted on the valve core, a pipeline is mounted on the valve body, and a valve rod is mounted on the pipeline. And a flange plate is fixedly mounted on the pipeline. According to the plug valve, the valve body is driven to rotate automatically through rotation of the first motor, the other side of the second bevel gear is meshed with a fluted disc, the fluted disc is connected with a hand wheel through a rotating shaft, a valve element is adjusted in a manual and automatic integrated mode, and high efficiency of the whole plug valve is guaranteed; an adjusting assembly on a valve element of the plug valve enables adjusting blocks at the two side ends to move outwards or inwards at the same time through rotation of a second motor, the positions of the adjusting blocks are conveniently moved to adjust the size of an opening in the valve element, then the petroleum exploitation efficiency is improved, and the purposes of high efficiency and convenience are achieved.
