The invention provides a bisecting flange ball valve, relates to the technical field of flange ball valves, and solves the problems of locking a rotating disc and locking bolts and the problems of reinforcing the flange ball valve and locking fixing bolts, the bisecting flange ball valve comprises a flange ball valve, and the flange ball valve is jointly composed of a left sealing pipeline, a right sealing pipeline and an extrusion block; the left sealing pipeline and the right sealing pipeline are fixedly connected through bolts, pressing rings are installed on the outer sides of the extrusion blocks, the extrusion blocks are arranged above the left sealing pipeline and the right sealing pipeline respectively, and the extrusion blocks are of an arc inclined structure. Locking of the rotating disc is achieved through the pressing base and the positioning base, the rotating disc is prevented from rotating due to the fact that the rotating disc is touched by the outside and mistakenly, the one-way teeth are arr
