| description | The invention belongs to the technical field of ball valves, and particularly relates to a three-section type ball valve of a soft sealing structure. A valve body comprises a sealing pipe, a valve ball, a valve seat, a valve cover and a valve rod, wherein the valve seat is positioned at the lower end of the valve body; the valve cover is positioned at the upper end of the valve body; the valve rod is rotationally connected inside the valve cover in a penetrating way; the lower end of the valve rod extends to the inside of the valve body and is fixed to the valve ball in an embedded connecting way; the sealing pipe rotationally connected with the valve ball is fixed inside the valve body and positioned outside the valve ball; and communicating openings are formed in the left end and the right end of the sealing pipe. According to the three-section type ball valve of the soft sealing structure, the valve ball is completely surrounded by the sealing pipe, and the sealing pipe is clamped, connected and fixed by i |
