Based on the specific embodiments of the present utility model, all other specific embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0033] Refer to Figures 1-5 , the present utility model provides a specific embodiment: a ball valve with automatic cleaning, including a first valve body 1, a second valve body 2 and a ball 7.

The cleaning mechanism 8 includes two first brackets 801, a first reciprocating lead screw 802, four second brackets 805 and two second reciprocating lead screws 806. The front end and the rear end of the outer wall of the rod body of the first reciprocating lead screw 802 are rotatably connected to the first brackets 801. A first scraping ring 803 is threadedly connected to the middle of the outer wall of the rod body of the first bracket 801;
[0034] The front end of the first reciprocating lead screw 802 penetrates through the first bracket 801 and is fixedly connected to a first impeller 804. The front and rear ends of the outer wall of the rod body of the second reciprocating lead screw 806 are rotatably connected to the second bracket 805. The middle parts of the outer wall of the rod body of the second reciprocating lead screw 806 are threadedly connected with second scraping rings 807. The front ends of the second reciprocating lead screws 806 penetrate through the second brackets 805 and are fixedly connected to second impellers 808. The upper end of the sphere 7 is fixedly connected to a valve stem 11.
[0035] Since the first impeller 804 and the second impeller 808 in the cleaning mechanism 8 are fixedly connected to the first reciprocating lead screw 802 and the second reciprocating lead screw 806, the first impeller 804 and the second impeller 808 are driven by the fast-flowing fluid, driving the first reciprocating lead screw 802 and the second reciprocating lead screw 806 to rotate. By using the fact that the first scraping ring 803 and the second scraping ring 807 are threadedly connected to the first reciprocating lead screw 802 and the second reciprocating lead screw 806, the first scraping ring 803 and the second scraping ring 807 clean the impurities attached to the inner walls of the sphere 7, the first valve body 1 and the second valve body 2 back and forth, preventing them from adhering firmly to the inner walls, which is convenient for subsequent workers to clean the ball valve.
[0036] A first fixing plate 3 is fixedly connected to the rear end of the outer wall of the first valve body 1, and a second fixing plate 4 is fixedly connected to the front end of the outer wall of the second valve body 2.

The front end and the rear end of the inner wall of the ball 7 are both fixedly connected to the first bracket 801. The front end of the inner wall of the first valve body 1 and the rear end of the inner wall of the second valve body 2 are both fixedly connected to two second brackets 805. By fixing the two first brackets 801 in the ball 7 and fixing the four second brackets 805 in groups of two in the first valve body 1 and the second valve body 2, stable support is provided for the first reciprocating screw rod 802 and the second reciprocating screw rod 806.

The inner walls on both sides of the first valve body 1 and the inner walls on both sides of the second valve body 2 are slidably connected to the outer walls on both sides of the second scraping ring 807. By making the first scraping ring 803 slidably connected to the ball 7 and making the two second scraping rings 807 slidably connected to the first valve body 1 and the second valve body 2 respectively, when the first scraping ring 803 and the second scraping ring 807 move along the first reciprocating screw rod 802 and the second reciprocating screw rod 806, they will not rotate, and the scraping operation can be carried out stably. First sealing blocks 9 and second sealing blocks 10 are respectively fixedly connected to the inner walls on one side of the first valve body 1 and the second valve body 2 close to the center of the ball 7. The outer walls at the front end and the rear end of the ball 7 are respectively in close contact with the first sealing block 9 and the second sealing block 10. By the close contact of the first sealing block 9 and the second sealing block 10 fixedly connected inside the first valve body 1 and the second valve body 2 with the ball 7, when the opening of the ball 7 is perpendicular to the flow channel of the valve body, the sealing performance can be improved to prevent the fluid from flowing continuously. The upper end of the valve stem 11 penetrates through the second valve body 2 and is fixedly connected to a handle 12. A second sealing ring 14 is fixedly connected to the top surface inside the second valve body 2, and the lower end of the second sealing ring 14 is in close contact with the valve stem 11. By the fixed connection between the valve stem 11 and the ball 7, the ball 7 can be driven to rotate inside the second valve body 2 by using the handle 12 to change the opening and closing of the valve. And by the close contact between the second sealing ring 14 inside the second valve body 2 and the valve stem 11, the sealing performance between the valve stem 11 and the second valve body 2 is improved to prevent fluid leakage. A first sealing ring 13 is fixedly connected to the outer wall at the rear end of the first valve body 1, and the rear end of the first sealing ring 13 is in close contact with the second valve body 2. By making the first sealing ring 13 fixedly connected to the first valve body 1 in close contact with the second valve body 2, after the first valve body 1 and the second valve body 2 are closed,The sealing performance therebetween is improved to prevent the fluid in the valve body from leaking.
[0037] Working principle: When using the ball valve with automatic cleaning, first, the staff use multiple bolts and nuts to cooperate with the first flange 5 and the second flange 6 to connect with the external pipeline, and connect the valve to the pipeline system. Then, the staff use the handle 12 to drive the ball 7 to rotate through the valve stem 11, change the orientation of the opening on the ball 7, and control the opening and closing of the valve. Secondly, the fast-flowing fluid drives the first impeller 804 and the second impeller 808 to rotate, so that the first reciprocating lead screw 802 and the second reciprocating lead screw 806 rotate on the first bracket 801 and the second bracket 805. The first scraping ring 803 and the second scraping ring 807 are threadedly connected to the first reciprocating lead screw 802 and the second reciprocating lead screw 806, so that the first scraping ring 803 and the second scraping ring 807 clean the impurities attached to the inner walls of the ball 7, the first valve body 1 and the second valve body 2 back and forth.
