Improved all-welded ball valve rod

The utility model relates to the technical field of all-welded ball valves, in particular to an improved all-welded ball valve rod which comprises flanges and a valve body, the flanges are installed on the two sides of the valve body respectively, a spherical valve plate is arranged in the middle of the valve body, the valve rod is arranged on the top of the spherical valve plate, and the top of the valve rod is attached to a sleeve rod. The pressing rod drives the conical block to move downwards, the conical block drives the spring to be compressed along the outer wall of the sliding rod, meanwhile, the conical block and the spherical block are released, then the sleeve rod is pulled to move through the handle and is separated from the valve rod, and therefore the handle is detached. The situation that a non-professional worker easily rotates the all-welded ball valve when the all-welded ball valve is unattended is prevented, when the valve rod needs to be rotated, the pressing rod is pressed, then the sleev
