High-tightness five-eccentric ball valve

A high-tightness five-eccentric ball valve structurally comprises a valve body, a connecting positioning ring is arranged at each of two ends of the valve body, a driving end is arranged at the top of the valve body, outer rings of the connecting positioning rings are in threaded connection with threaded fixing sleeves, sealant storage cavities are formed in the threaded fixing sleeves, and sealing bolts are screwed on the outer walls of the threaded fixing sleeves. A pipeline with threads at the end is in butt joint with the connecting positioning ring, then the threaded fixing sleeve is rotated to be screwed to the end of the pipeline from the connecting positioning ring, the pipeline and the threaded fixing sleeve are connected and fixed, and then the sealing bolt is screwed out, the bottom of the sealing bolt is moved out of the liquid outlet channel, and a flow guide hole in the outer side enters the sealant storage cavity. And the sealant flows into the liquid outlet channel through the flow guide hole
