A ball valve includes a body, two side covers, a central shaft, a handle, a ball, and two ball pads. The ball defines a main flow hole and a secondary flow hole perpendicular to and is not communicated with the main flow hole. One ball pad defines a main passage hole and a secondary passage hole corresponding to the main flow hole and the secondary flow hole. One side cover defines a main through hole and a secondary through hole corresponding to the main passage hole and secondary passage hole. When 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.

1. A ball valve structure improvement, comprising: a body (1), a first side cover (2), a second side cover (9), a central shaft (3), a handle (4), a ball (7), a first ball pad (6), and a second ball pad (8), said first ball pad (6) and said second ball pad (8) respectively mounted on two sides of sa
1. A ball valve structure improvement, comprising: a body (1), a first side cover (2), a second side cover (9), a central shaft (3), a handle (4), a ball (7), a first ball pad (6), and a second ball pad (8), said first ball pad (6) and said second ball pad (8) respectively mounted on two sides of said ball (7), said central shaft (3) having a first end extended into said body (1) and inserted into said ball (7) for rotating said ball (7), and a second end extended outward from said body (1) and secured with said handle (4), said first side cover (2) and said second side cover (9) respectively mounted on two sides of said body (1), for sealing said ball (7), said first ball pad (6), and said second ball pad (8) in said body (1), wherein,a main flow hole (70) is defined through said ball (7), a secondary flow hole (71) is eccentrically defined through said ball (7), said secondary flow hole (71) is perpendicular to and is not communicated with said main flow hole (70), said second ball pad (8) mounted on one side of said ball (7) defines a main passage hole (81) located at a position opposite to said main flow hole (70), and a secondary passage hole (82) located at a position opposite to said secondary flow hole (71), said second side cover (9) mounted beside said second ball pad (8) defines a main through hole (90) located at a position opposite to said main passage hole (81), and a secondary through hole (91) located at a position opposite to said secondary passage hole (82) and extended to outside of said ball valve, so that when said ball (7) is rotated to a position where said secondary flow hole (71), said secondary passage hole (82), and said secondary through hole (91) communicate with each other, a fluid contained in a pipe is introduced to outside of said ball valve, so that said fluid contained said pipe can be sampled without having to dismantle said pipe, thereby facilitating a sampling work in each section of said pipe.
