valve ball disassembly and assembly: when the rubber bag (19) is pressurized inside until the rubber bag is completely blocked after being opened, the limiting bolt (37) above the valve body (1) is disassembled, then the limiting frame (3) is taken out, and meanwhile, the valve ball (21) in the valve body (1) is connected with the valve ball (21) through the thread through the threaded rod (34), so that the valve ball (21) is replaced, the valve ball (21) is replaced after being installed in the valve body (1), and then the pressure in the rubber bag (19) is relieved, so that the valve body (1) is started.
8. The method of using a top-loading ball valve for oil transportation according to claim 7, comprising the steps of:
the ball valve freedom degree adjusting method comprises the following steps: the position of the limiting frame (3) is adjusted through the installation positions of the adjusting limiting bolts (37) and the limiting frame (3), so that the lifting height position of the valve ball (21) is adjusted.
