[0024] REFERENCE Figures 1-5 A kind of ball valve of high valve opening control degree, including valve body 2, valve body 2 is equipped with round ball 4, the side of round ball 4 is equipped with the water passage that passes through round ball 4 and is connected with valve body 2, the top outer wall of valve body 2 is welded with round tube 7, rotating shaft 8 is rotatably connected in round tube 7, the bottom end of rotating shaft 8 passes through valve body 2 and is fixed with round ball 4, the top end of rotating shaft 8 is fixed with the wrench 10 for making rotating shaft 8 rotate by bolt, the bottom of wrench 10 is equipped with the insert assembly for the fixed rotating shaft 8, the outside of round tube 7 is equipped with multiple indicating line 5 at top position, the outside of wrench 10 is fixed with the indicating needle 14 for indicating indicating line 5 by bolt, the side of valve body 2 water inlet is fixed with filter box 3 by bolt, filter box 3 is equipped with filter assembly, when needing to adjust, make insert assembly no longer fixed rotating shaft 8, at this time, rotating shaft 8 can be rotated by wrench 10, rotating shaft 8 will drive round ball 4 to rotate in valve body 2, and because indicating line 5 on round tube 7 is marked to water flow, so rotating shaft 8 can be observed by indicating needle 14 on wrench 10 at the position of indicating line 5 during the process of rotation to change the water flow of valve body 2, when valve body 2 is adjusted to the appropriate water flow, so as to fix rotating shaft 8 by insert assembly, so as to fix the water flow of valve body 2 adjusted, it is convenient to better observe and control the size of water flow, improve the accuracy of ball valve control.

[0025] In this utility model, the insertion assembly includes an L-shaped groove 9, which is opened on one side of the wrench 10. The L-shaped groove 9 is open downwards. A plug bracket 12 is slidably connected inside the L-shaped groove 9. The top of the round tube 7 is provided with multiple plug holes 6 corresponding to the indicator marks 5, and the plug bracket 12 is inserted into the plug holes 6. Two limiting rods 13 are welded to the bottom of the wrench 10, and the limiting rods 13 pass through the plug bracket 12, allowing the plug bracket 12 to move vertically up and down. Springs 11 are sleeved on the outer sides of the two limiting rods 13, and the two ends of the springs 11 are fixed to the wrench 10 and the plug bracket 12 respectively. When it is necessary to adjust the water flow of the valve body 2, the plug bracket 12 is pressed and moves upward along the limiting rods 13. The plug bracket 12 will move upward in the L-shaped groove 9 and squeeze the springs 11, thereby disengaging the plug bracket 12 from the plug holes 6. At this time, the rotating shaft 8 can be rotated by the wrench 10 to adjust the water flow.

[0026] The filter assembly includes a mounting bracket 16, which contains filter cotton 15. The mounting bracket 16 is installed inside the filter box 3. The top inner wall of the filter box 3 has multiple mounting slots 18. The mounting bracket 16 is fixed in the mounting slots 18 by bolts. U-shaped slots 19 are provided on both sides of the filter box 3 at the top position. U-shaped brackets 17 are welded to both sides of the mounting bracket 16, and the U-shaped brackets 17 are inserted into the U-shaped slots 19. The filter box 3 is installed on one side of the inlet of the valve body 2. At this time, the water entering the valve body 2 will be filtered by the filter cotton 15, thereby cleaning the impurities in the water and ensuring the cleanliness of the water. A flange 1 for installing the valve body 2 is welded to one side of the valve body 2.

[0027] Working principle: When needed, press the insert 12 to move upward along the limit rod 13. The insert 12 will move upward in the L-shaped groove 9 and squeeze the spring 11, thereby disengaging the insert 12 from the socket 6. At this time, the rotating shaft 8 can be rotated by the wrench 10. The rotating shaft 8 will drive the ball 4 to rotate inside the valve body 2. Since the indicator mark 5 on the round tube 7 marks the water flow rate, the water flow rate of the valve body 2 can be observed by the position of the indicator needle 14 on the wrench 10 at the indicator mark 5 during the rotation of the rotating shaft 8. When the valve body 2 is adjusted to the appropriate water flow rate, release the insert 12. At this time, the insert 12 will return to its original position under the action of gravity and the spring 11, thereby inserting the insert 12 into the corresponding socket 6 to fix the rotating shaft 8, thus fixing the water flow rate adjusted by the valve body 2. This facilitates better observation and control of the water flow rate and improves the accuracy of ball valve control.
