Wherein, the valve ball has an upper hole at an upper end of the longitudinal axis, and one end of the valve stem has a block fixed to the upper hole.

Wherein, the valve ball has a lower card hole at a lower end of the longitudinal axis, and the valve seat pivotally has a rotating member corresponding to the bottom edge of the pivot hole to be fixed to the lower card hole.

With the above, one of the functions of this creation can be achieved. The overall valve ball of the present invention is half-spherical, and the inside of the valve ball has a larger concave portion and a lower concave portion than the conventional one, so that the wall thickness of the valve ball is thinner and more It is close to the hollow shape. Therefore, the overall effect is increased, which can save the manufacturing material of the valve ball, thereby reducing the manufacturing cost of the overall ball valve structure, and is more economical than the conventional one.

With the above, the second effect of this creation is that the valve ball is half-spherical and eccentrically arranged, so that the contact surface between the valve ball and the inner edge of the valve seat is reduced. Therefore, when the valve handle rotates the valve ball, It can reduce the friction between the ball and the inner edge of the seat.

Referring to FIG. 7 and FIG. 8 , when the user wants to perform the creation, the positioning pin 43 between the handle 41 and the pressing member 42 is pulled away, so that pressure can be applied to the pressing member 42 to fix the pressing member 42. The pin 44 is a fulcrum and is separated from the tooth block 14. At this time, the user rotates the handle 41 in a clockwise direction, so that the valve stem 30 can be linked to rotate the valve ball 20, so that the opening 21 and the water inlet hole 11 of the valve seat 10 are generated. The angular deviation, in turn, changes the flow rate of the fluid, and the area of the water outlet hole 12 is reduced by the fan-shaped opening 26. Therefore, in addition to controlling the flow rate of the fluid, the rotating valve ball 20 can also adjust the pressure of the fluid. When the handle 41 is rotated to an angle, the user can secure the pressing member 42 to one of the blocks 14 to achieve fluid flow and pressure.

Since the whole valve ball 20 of the present invention has a semi-spherical shape, and the inside of the valve ball 20 has a concave portion 22 and a lower concave portion 23 compared with the valve ball 2 of the conventional FIG. 1 and FIG. 2, the wall of the valve ball 20 is made. The thickness is thinner and closer to the hollow shape. Therefore, the overall effect is increased, the manufacturing material of the valve ball 20 can be saved, and the manufacturing cost of the overall ball valve structure can be reduced, which is more economical than the conventional one.

In addition, since the valve ball 20 is substantially spherical in shape and eccentrically disposed, the contact surface between the valve ball 20 and the inner edge of the valve seat 10 is reduced. Therefore, when the valve handle 40 rotates the valve ball 20, the valve ball 20 can be reduced. Friction of the inner edge of the valve seat 10.
