An anti-clogging ball valve includes a valve body 1, a valve ball 2 inside the valve body 1, a valve stem 3 fixedly connected to the top of the valve ball 2, a handle 4 fixedly connected to the valve stem 3 extending from the top of the valve body 1, a concave ring 5 on one side of the valve body 1, and a water inlet pipe 6 on the side of the concave ring 5 away from the valve body 1; a circular ring 501 is fixed on the concave ring 5, a limit ring 502 is fixed inside the circular ring 501, a filter ring 503 is disposed inside the circular ring 501, a filter screen 504 is fixed inside the filter ring 503, a fixed ring 505 is disposed on the side of the circular ring 501 away from the concave ring 5, a compression ring 506 is fixed on one side of the fixed ring 505, the compression ring 506 overlaps with the filter ring 503, and several screws 507 are fixed on one side of the circular ring 501. One end of each screw 507 passes through a through hole 508 in the fixed ring 505 and is locked with a nut 509 on its outer side.

[0023] With the above technical solution, before the valve body 1 is used, the filter ring 503 and the filter screen 504 are installed inside the ring 501. Then, the fixing ring 505 is fixed on the ring 501 by the cooperation of the screw 507 and the nut 509. The two sides of the filter ring 503 are fixed by the cooperation of the limiting ring 502 and the squeezing ring 506. Then, the concave ring 5 is installed on the valve body. At the same time, the ring 501 is inserted into the valve body 1, so that when the valve body 1 is in use, the filter screen 504 can filter impurities in the fluid, avoid impurities from clogging the valve ball 2, and enable the valve body 1 to be used normally.

[0024] Reference Figure 1 and Figure 3 A first threaded ring 510 is fixed on the concave ring 5, and a first sealing ring 101 is fixed on one end of the valve body 1. The first threaded ring 510 passes through the first sealing ring 101 and is screwed into the first threaded groove 102 opened in the valve body 1. By screwing the first threaded ring 510 into the first threaded groove 102, the concave ring 5 can be installed and fixed on the valve body 1, making the installation of the concave ring 5 and the valve body 1 more convenient. The first sealing ring 101 is used to improve the sealing performance at the connection between the concave ring 5 and the valve body 1 to prevent fluid leakage.

[0025] Reference Figure 1 and Figure 2 A second threaded ring 601 and a second sealing ring 602 are fixed on one side of the water inlet pipe 6. The second threaded ring 601 is screwed into the second threaded groove 511 of the concave ring 5. After the concave ring 5 is installed on the valve body 1, the second threaded ring 601 on one side of the water inlet pipe 6 is screwed into the second threaded groove 511. Through the cooperation between the second threaded ring 601 and the second threaded groove 511, the water inlet pipe 6 can be installed on one side of the concave ring 5, making the installation of the water inlet pipe 6 more convenient. The second sealing ring 602 is used to improve the sealing performance at the connection between the concave ring 5 and the water inlet pipe 6 to prevent fluid leakage.

[0026] Reference Figure 4 and Figure 5 Several filter rings 503 are provided, and the filter rings 503 are symmetrically distributed inside the ring 501. Several connecting rods 512 are provided between adjacent filter rings 503. Both ends of the connecting rods 512 are inserted into the slots 513 opened in the filter rings 503. The filter holes of the filter screens 504 in the filter rings 503 decrease in size from right to left, which can effectively improve the filtration effect of impurities in the fluid. Furthermore, the filter rings 503 can be connected together by the cooperation of the connecting rods 512 and the slots 513, making the filter rings 503 more stable during use.

[0027] Reference Figure 5The connecting rod 512 has a movable groove 514 inside. A spring 515 is fixedly connected to the bottom wall of the movable groove 514. A limit plate 516 is fixedly connected to the top of the spring 515. A fixing rod 517 is fixedly connected to the top of the limit plate 516. The top of the fixing rod 517 passes through the insertion hole 518 of the connecting rod 512 and is inserted into the fixing hole 519 of the filter ring 503. Pressing the fixing rod 517 in the fixing hole 519 causes the fixing rod 517 to disengage from the fixing hole 519 and enter the movable groove 514, releasing the restriction of the fixing rod 517 on the connecting rod 512. Then the connecting rod 512 can be removed from the slot 513, allowing the replacement of a single filter ring 503. After replacement, the connecting rod 512 is inserted into the slot 513. The connecting rod 512 is fixed in the slot 513 by the cooperation of the fixing rod 517 and the fixing hole 519, thus completing the installation of the new filter ring 503 and making the replacement of the filter ring 503 more convenient.

[0028] The implementation principle of an anti-clogging ball valve according to an embodiment of this utility model is as follows: Before the valve body 1 is used, the filter ring 503 and the filter screen 504 are installed inside the ring 501. Then, the fixing ring 505 is fixed on the ring 501 by the cooperation of the screw 507 and the nut 509. The two sides of the filter ring 503 are fixed by the cooperation of the limiting ring 502 and the squeezing ring 506. Then, the concave ring 5 is installed on the valve body. At the same time, the ring 501 is inserted into the valve body 1, so that when the valve body 1 is in use, the filter screen 504 can filter impurities in the fluid, avoid impurities from clogging the valve ball 2, and enable the valve body 1 to be used normally.
