[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This application provides a ball valve ball for controlling liquid flow with filtration and anti-clogging, which solves the problems of existing ball valves having relatively simple filtration structures, using a single filter screen, resulting in limited filtration effect and easy clogging. This requires frequent disassembly, cleaning, or replacement of filter components, increasing maintenance costs and downtime.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] This utility model discloses a ball valve body for controlling the flow of filtered, anti-clogging liquids.

[0030] According to the appendix Figures 1-5 As shown, it includes a spherical unit 1 and a filter unit 2 installed inside the spherical unit 1. The filter unit 2 includes:

[0031] The fine filtration assembly 21 includes a mounting ring 211 and a filter cone 212. The filter cone 212 is fixedly disposed inside the spherical unit 1 by the mounting ring 211. The filter cone 212 may optionally have multiple filter holes for filtering impurities.

[0032] The coarse anti-clogging component 22 includes a screen 221 and a mounting block 222. The screen 221 is mounted on the end of the filter cone 212 via the mounting block 222, and the screen 221 serves to block large particles of debris.

[0033] The dual filtration structure of the fine filtration assembly 21's filter cone 212 and the coarse anti-clogging assembly 22's screen 221 effectively intercepts large particles and tiny impurities in the liquid, greatly improving the filtration effect and ensuring the cleanliness of the liquid flowing through the ball valve. The screen 221 of the coarse anti-clogging assembly 22 can pre-intercept large particles, reducing the probability of large particles entering the fine filtration assembly 21's filter cone 212 and lowering the risk of clogging in the filter cone 212.

[0034] Furthermore, the spherical unit 1 includes:

[0035] The sphere body 11 has a through hole, and the filter unit 2 is installed inside the through hole;

[0036] The mounting groove 12 is located at one end of the sphere body 11;

[0037] Rotating groove 13 is located at the other end of the sphere body 11.

[0038] The main body 11 of the ball has a through hole through which liquid flows in the ball valve. The filter unit 2 is installed inside the through hole to filter the flowing liquid.

[0039] The mounting groove 12 is provided at one end of the ball body 11 and is used to install the valve stem connector of the ball valve, so as to realize the opening and closing control of the ball valve.

[0040] The rotating groove 13 is located at the other end of the ball body 11 and is used to connect with the interior of the ball valve.

[0041] Furthermore, the end of the filter cone 212 is provided with a mounting surface, and a fixing block 213 is fixedly connected to the mounting surface.

[0042] Furthermore, the mounting block 222 fits tightly against the mounting surface.

[0043] Furthermore, a fixing groove 223 is provided on the side of the mounting block 222, and the fixing block 213 is inserted into the fixing groove 223. The mounting block 222 and the fixing block 213 are fixedly connected by bolts.

[0044] Furthermore, an embedding groove is provided on the other side of the mounting block 222, and a sealing cover 224 is inserted into the embedding groove to seal and protect the bolt.

[0045] Furthermore, the sealing cap 224 is interference-fitted with the inner wall of the embedded groove.

[0046] A fixing block 213 is formed on the end mounting surface of the filter cone 212, and cooperates with the mounting block 222 to install the screen 221. A fixing groove 223 is formed on the side of the mounting block 222, and the fixing block 213 is inserted into the fixing groove 223. Then, the mounting block 222 and the fixing block 213 are fixedly connected by bolts to ensure a stable connection between the screen 221 and the filter cone 212.

[0047] An embedding groove is provided on the other side of the mounting block 222.

The sealing cap 224 is interference-fitted with the inner wall of the embedding groove to ensure a sealing effect.

[0048] When the ball valve is in the open position, liquid flows in from one end of the ball unit 1 and first passes through the screen 221 of the coarse anti-clogging component 22. The screen 221 has large mesh size, which can effectively intercept large particles in the liquid and prevent these large particles from entering the subsequent filtration structure.

[0049] The liquid, after initial filtration by screen 221, continues to flow into the filter cone 212 of the fine filtration assembly 21. The filter cone 212 has multiple small filter holes, capable of finely filtering tiny impurities in the liquid, further purifying it. The clean liquid filtered by the filter cone 212 flows out from the other end of the spherical unit 1, completing the liquid flow control and filtration process.
