[0025] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0026] As shown in Figures 1-5 The technical solutions provided by the present application are as follows:

[0027] The adjustable ball valve comprises a ball valve body 1, a joint one 2 and a joint two 3 arranged at the left and right ends of the ball valve body 1 respectively, a joint three 4 arranged at the end of the joint two 3 away from the ball valve body 1, a joint four 5 arranged at the other end of the joint three 4, a rotating sleeve 6 movably arranged between the joint three 4 and the joint four 5, an adjusting mechanism arranged between the rotating sleeve 6 and the joint three 4, the adjusting mechanism comprising an adjusting disc 7, the adjusting disc 7 being fixedly installed on the inner side of the end of the joint three 4 close to the rotating sleeve 6, three flow channels 8 arranged on the adjusting disc 7, a butt joint groove 9 penetratingly arranged on one side of the middle part of the rotating sleeve 6, the diameters of the three flow channels 8 gradually decreasing in the clockwise direction, a positioning mechanism arranged between the rotating sleeve 6 and the joint four 5, a movable groove 10 arranged on the same side of the joint three 4 and the joint four 5, a movable ring 11 movably connected with the movable groove 10 arranged at the outer wall of the two ends of the rotating sleeve 6, the positioning mechanism comprising a pointer 12, the pointer 12 being arranged on the right outer part of the rotating sleeve 6, four positioning lines 13 arranged on the left outer part of the joint four 5 at equal radian, and anti-skid diagonal lines arranged on the outer wall of the rotating sleeve 6.
