This not only increases the difficulty of operation but also adversely affects the production process. Therefore, developing an adjustable ball valve that can effectively solve the above problems is of significant practical importance. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-3 This utility model provides a technical solution:

[0034] Example 1: An adjustable ball valve includes a valve unit 1, and an anti-deflection unit 2 is provided on the valve unit 1;

[0035] Valve unit 1 includes:

[0036] Valve body 11;

[0037] Valve cover 13 is located above valve body 11, and multiple limiting holes 131 are equidistantly opened on the circumference of valve cover 13;

[0038] Adjusting element 15 is disposed above valve cover 13 and is used to adjust the liquid flow rate of the ball valve.

[0039] Anti-deflection unit 2 includes:

[0040] Limiting block 21 is movably engaged within limiting hole 131;

[0041] The bottom end of the slide rod 22 is fixedly connected to the limiting block 21, and the slide rod 22 is slidably connected to the adjusting member 15.

[0042] Spring 23 is sleeved on the outside of slide bar 22 and is used to press the limit block 21 to engage with valve cover 13.

[0043] Furthermore, valve unit 1 also includes:

[0044] Flange 12, two sets of flange 12 are provided, and the two sets of flange 12 are respectively fixedly connected to both sides of valve body 11;

[0045] A valve stem 14 is rotatably connected to the valve cover 13. The top end of the valve stem 14 is fixedly connected to the adjusting member 15, and the bottom end of the valve stem 14 is provided with a V-shaped valve disc. When the adjusting member 15 rotates, the valve stem 14 drives the V-shaped valve disc to rotate within the valve body 11, changing the cross-sectional area of ​​the fluid passage and thus achieving flow regulation.

[0046] Furthermore, a V-shaped valve disc is fixedly connected to the bottom end of the valve stem 14, and the V-shaped valve disc is rotatably connected inside the valve body 11. The adjusting component 15 is located above the valve cover 13. By rotating the adjusting component 15, the valve stem 14 can be rotated, thereby controlling the opening degree of the V-shaped valve disc inside the valve body 11, thus regulating the liquid flow rate.

[0047] Furthermore, a fixing block 132 is fixedly connected to the valve cover 13, which is used to limit the rotation angle of the adjusting member 15.

[0048] Example 2: An adjustable ball valve, including a valve unit 1, wherein an anti-deflection unit 2 is provided on the valve unit 1;

[0049] Valve unit 1 includes:

[0050] Valve body 11;

[0051] Valve cover 13 is located above valve body 11, and multiple limiting holes 131 are equidistantly opened on the circumference of valve cover 13;

[0052] Adjusting element 15 is disposed above valve cover 13 and is used to adjust the liquid flow rate of the ball valve.

[0053] Anti-deflection unit 2 includes:

[0054] Limiting block 21 is movably engaged within limiting hole 131;

[0055] The bottom end of the slide rod 22 is fixedly connected to the limiting block 21, and the slide rod 22 is slidably connected to the adjusting member 15.

[0056] Spring 23 is sleeved on the outside of slide bar 22 and is used to press the limit block 21 to engage with valve cover 13.

[0057] Furthermore, the anti-deflection unit 2 also includes:

[0058] Pull block 24 is fixedly connected to the top of slide bar 22;

[0059] Sleeve block 25 is located below pull block 24 and is slidably connected to slide rod 22;

[0060] Positioning component 26 is disposed on one side of sleeve block 25. Positioning component 26 is movably engaged with slide rod 22 and is used to fix the position of slide rod 22. The positioning component 26 ensures that during the rotation adjustment of adjusting component 15, limiting block 21 is fixed below adjusting component 15, which will not affect the adjustment of adjusting component 15 and ensures the stability of ball valve adjustment.

[0061] Furthermore, one end of the spring 23 is fixedly connected to the limiting block 21, and the other end of the spring 23 is fixedly connected to the adjusting member 15.

[0062] Furthermore, the sleeve block 25 is fixedly connected to the adjusting component 15. When it is necessary to adjust the liquid flow rate, the user first pulls the pull block 24, causing the slide rod 22 to drive the limiting block 21 away from the limiting hole 131. Then, the positioning component 26 fixes the position of the slide rod 22, while the limiting block 21 is fixed above the limiting hole 131. At this time, the adjusting component 15 can rotate freely. After adjustment, the positioning component 26 is separated from the slide rod 22, and then the pull block 24 is released. The spring 23 returns to its original deformation, and the spring 23 presses the limiting block 21 to engage again in the limiting hole 131, fixing the position of the adjusting component 15. By using the spring 23 to press the limiting block 21 into the limiting hole 131 of the valve cover 13, the rotation of the adjusting component 15 under the pressure of the water flow is effectively prevented, thereby ensuring the stability of the liquid flow rate.
