[0002] A ball valve is a kind of valve, and its opening and closing part (ball) is driven by a valve stem and rotates around the axis of the valve stem. The main function of the ball valve is to control the flow direction and flow rate of the fluid, including uses such as on-off and cut-off valves. The advantages of the ball valve include small fluid resistance, not being easily eroded by the medium, and only requiring a 90-degree rotation operation and a very small rotational torque in the pipeline to close tightly.

[0025] When it is necessary to control the flow of hard water through the adjusting rod 5 and use the valve ball 4 in the valve ball groove 3, align the sealing ring 8 on the side wall of the mounting plate 9 with the sealing ring 8 on the side wall of the valve seat body 1 in advance, and then place the first connecting piece 13 against the side wall of the mounting plate 9. At this time, the positions of the four No. 1 threaded holes 14, the No. 2 threaded holes 15, and the first threaded groove 6 match, and then four mounting bolts 19 are used to thread into the No. 1 threaded holes 14, the No. 2 threaded holes 15, and the first threaded groove 6 to achieve threaded fixation of the first connecting piece 13, the mounting plate 9, and the valve seat body 1. When hard water enters the mounting plate 9 through the first connecting piece 13 in the water inlet pipe 12, it will be filtered by the ion exchange resin filter screen 11. The ion exchange resin in the ion exchange resin filter screen 11 will remove heavy metal ions and impurities in the water and can adjust the hardness of the water. At this time, the filtered water will not form scale in the valve ball groove 3 after entering the valve seat body 1, thereby avoiding scale deposition in the valve ball groove 3 to corrode metal substances and prolonging the service life of the valve seat body 1.

[0026] Furthermore, an adjusting disk is fixedly connected to the upper end of the adjusting rod 5, and the adjusting disk is a metal rotating disk.

[0028] Furthermore, four second thread grooves 7 are opened on the side wall of the valve seat body 1 away from the first thread groove 6, and a second connecting member 16 is arranged outside the valve seat body 1. A water outlet pipe 18 is fixedly connected to the side wall of the second connecting member 16, and four No. 3 threaded holes 17 matching the second thread grooves 7 are opened on the side wall of the second connecting member 16.

[0029] By providing the second thread groove 7, the second connecting piece 16, and the No. 3 threaded hole 17, when the valve seat body 1 needs to be connected to the water outlet pipe 18, the second connecting piece 16 is pressed against the side wall of the valve seat body 1 and the four No. 3 threaded holes 17 are matched with the positions of the four second thread grooves 7. At this time, the mounting bolts 19 are threaded into the four No. 3 threaded holes 17 and the four second thread grooves 7. At this time, the second connecting piece 16 is fixedly connected to the side wall of the valve seat body 1, so that the water flow in the valve seat body 1 can enter the water outlet pipe 18 through the second connecting piece 16, and the connection between the valve seat body 1 and the water outlet pipe 18 is more convenient;

The ion exchange resin in the ion exchange resin filter plate 11 will remove heavy metal ions and impurities in the water and can adjust the hardness of the water. At this time, the filtered water will not form scale in the valve ball groove 3 after entering the valve seat body 1, avoiding the corrosion of metal substances due to the deposition of scale in the valve ball groove 3 and extending the service life of the valve seat body 1.
