[0002] Electric ball valves are important actuators in industrial automation control systems. An electric ball valve is a valve in which the valve disc rotates around the axis of the valve stem. The change in the valve seat opening is directly proportional to the valve disc stroke. They are mainly used to cut off or connect the medium in pipelines, and can also be used for fluid regulation and control, making them a type of pipeline pressure component in industrial automation process control.

[0003] The filtration function of existing electric ball valves is usually achieved through a built-in filter. However, when too much debris accumulates, the filter needs to be cleaned regularly, which is extremely inconvenient.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 This is a schematic diagram of the overall structure of the flow-adjustable electric ball valve of this utility model; Figure 2 This is a schematic diagram of the internal structure of the flow-adjustable electric ball valve of this utility model. Figure 3 This is a schematic diagram of the filter screen structure of the flow-adjustable electric ball valve of this utility model; Figure 4 A schematic diagram of the arc-shaped clamping bar structure of the flow-adjustable electric ball valve provided by this utility model. The flow-adjustable electric ball valve includes: a valve body 1, a connecting pipe 2 fixedly connected to the top of the valve body 1, a housing 3 fixedly connected to the top end of the connecting pipe 2, an actuator provided inside the housing 3, and a filtering mechanism provided on the valve body 1;

[0024] The actuator includes a drive motor 4, which is fixedly installed inside the housing 3. The output end of the drive motor 4 is fixedly connected to a worm gear 5, and the other end of the worm gear 5 is rotatably connected to the inner wall of the housing 3. A valve stem 6 is rotatably connected through the housing 3, and a worm wheel 7 is fixedly sleeved on the valve stem 6. The worm wheel 7 meshes with the worm gear 5, and a ball 8 is fixedly connected to the bottom end of the worm wheel 7.

[0025] The filtration mechanism includes a filter screen 9, which is fixedly connected to the inner wall of the sphere 8. A U-shaped plate 10 is provided below the valve body 1, and a circulation pump 11 is fixedly installed on the U-shaped plate 10. A main pipe 12 is fixedly connected to the outlet end of the circulation pump 11, and the main pipe 12 is connected to the valve body 1. A secondary pipe 13 is fixedly installed on the other side surface of the valve body 1, and a filter tube 14 is installed on the secondary pipe 13. A water storage tank 15 is fixedly connected to the U-shaped plate 10. The inlet end of the circulation pump 11 is connected to the water storage tank 15, and the other end of the filter tube 14 is connected to the water storage tank 15.

[0026] like Figure 4As shown, two arc-shaped strips 16 are fixedly connected to both ends of the shaped plate 10. An arc-shaped clamping strip 17 is hinged to the top of the arc-shaped strip 16, and a bolt 18 is threaded onto the arc-shaped clamping strip 17.

[0027] The filter mechanism can be fixed to the valve body 1 by means of the arc-shaped clamp 17 and the bolt 18, which facilitates the disassembly of the filter mechanism.

[0028] like Figure 4 As shown, the outer wall of the water storage tank 15 is fixedly fitted with a fixing sleeve 19, and the bottom of the fixing sleeve 19 is fixedly connected to the bottom surface of the U-shaped plate 10 by screws.

[0029] By setting the fixing sleeve 19, the stability of the water storage tank 15 can be enhanced, and the water storage tank 15 can be prevented from becoming loose.

[0030] like Figure 4 As shown, a second fixing sleeve 20 is fixedly sleeved on the circulating pump 11, and the bottom of the second fixing sleeve 20 is fixedly connected to the U-shaped plate 10 by screws;

[0031] By setting the fixing sleeve 20, the circulation pump 11 can be securely installed on the U-shaped plate 10.

[0035] The use of stainless steel filter screen 9 extends its service life and eliminates the need for replacement.

[0036] The working principle of the flow-adjustable electric ball valve provided by this utility model is as follows:

[0037] First step: When in use, the drive motor 4 starts after receiving the signal, driving the worm 5 to rotate. The worm 5 drives the worm wheel 7 to rotate, thereby driving the ball 8 to rotate, realizing the flow regulation of the valve body 1. At the same time, when the valve body 1 has been flowing with water for a long time and too much debris is blocked on the filter screen 9, the drive motor 4 is started to drive the ball 8 to rotate, rotating the water passage in the ball 8 to the secondary pipe 13, while cutting off the water flow in the valve body 1, and making the main pipe 12, the secondary pipe 13 and the water passage in the ball 8 form a connected pipeline.

[0038] The second step: Then start the circulation pump 11 to transport the cleaning water in the water storage tank 15 from the main pipe 12 to the ball 8, thereby washing the debris on the filter screen 9 into the filter tube 14. Then the worker replaces the filter tube 14 to complete the cleaning of the filter screen 9. Finally, start the drive motor 4 again to rotate the ball 8 back to its original position.

[0039] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model.
