Abstract

The objective of the present invention is to provide a ball valve auxiliary device capable of being remotely adjusted. The opening degree of a valve can be directly adjusted according to the positionof the valve and through remote location. According to a folding type supporting adjusting leg, through ingenious combination of supporting legs, a connecting plate, a spring and other devices, the folding effect of the supporting legs can be achieved. When the folding type supporting adjusting leg does not need to work, the supporting legs are folded, telescopic rods are contracted, and space issaved; during work, the supporting legs are easily straightened to achieve the supporting effect, the telescopic rods are unfolded, remote accurate positioning is achieved according to the position ofthe valve, the opening degree of the valve can be directly adjusted, and operation is convenient and fast. In the opening and closing process, a gear box can adjust the backlash of a transmission pair by axially moving a variable-tooth-thickness involute gear based on the equivalent principle of axial movement and circumferential rotation of a spiral surface, so that the efficiency of the transmission pair is improved, and accurate adjustment of the valve is achieved.
