text: a secondary passage hole located at a position opposite to the secondary flow hole, the second side cover mounted beside the second ball pad defines a main through hole located at a position opposite to the main passage hole, and a secondary through hole located at a position opposite to the secondary passage hole and extended to outside of the ball valve, so that when the ball is rotated to a position where the secondary flow hole, the secondary passage hole, and the secondary through hole communicate with each other, a fluid contained in a pipe is introduced to outside of the ball valve, so that the fluid contained the pipe can be sampled without having to dismantle the pipe, thereby facilitating a sampling work in each section of the pipe.
