[0021] Combination Figure 1-Figure 4 A regulating valve with water purification function includes a water flow pipe 1 and a filter body 2. The filter body 2 is arranged at the lower end of the water flow pipe 1. The filter body 2 and the water flow pipe 1 are connected. One end of the water flow pipe 1 is an inlet 11, and the other end is an outlet 13. A blocking block 12 is fixed between the inlet 11 and the outlet 13. The water flow must first flow into the filter body 2 from the inlet 11, and then flow from the filter body 2 to the outlet 13. An annular groove 21 is provided on the inner side of the upper end of the filter body 2. A perforated circular plate 3 is provided in the annular groove 21. A large circular hole 31 is provided on the perforated circular plate 3. A small circular hole 31 is provided on one side of the large circular hole 31. A sealing ring 33 is provided on the outer fixed sleeve of the perforated circular plate 3 to prevent water from flowing into the edge gap of the perforated circular plate 3. A rotating ring 4 is provided at the lower end of the perforated circular plate 3. The rotating ring 4 is rotatably arranged in the annular groove 21. A large circular piece 41 is fixedly arranged in the rotating ring 4. A small circular piece 42 is fixedly arranged on one side of the large circular piece 41. A rotating shaft 5 is fixedly arranged between the large circular piece 41 and the small circular piece 42. The rotating shaft 5 passes through the blocking block 12 and the perforated circular plate 3 and is rotatably connected thereto. By rotating the rotating ring 4, different covering effects are achieved on the large circular hole 31 and the small circular hole 32, thereby realizing the opening and closing of water flow and the regulation of water flow.

[0022] The diameter of the large disc 41 is larger than the aperture of the large circular hole 31, and the diameter of the small disc 42 is larger than the aperture of the small circular hole 32. A fixing ring 6 is provided at the lower end of the rotating ring 4, and a fixing strip 61 is fixedly provided in the middle of the fixing ring 6. A filter screen 7 embedded in the fixing strip 61 and the inner wall of the filter body 2 is provided on one side of the lower end of the fixing strip 61. The filter screen 7 is arranged on the side of the perforated circular plate 3 that is biased towards the small circular hole 32. A turntable 51 is fixedly provided at the upper end of the rotating shaft 5, and a protrusion 52 is fixedly provided on the turntable 51. A threaded funnel 8 is provided at the lower end of the filter body 2, and a threaded groove 81 is provided on the inner side of the threaded funnel 8. The threaded funnel 8 is threadedly connected to the filter body 2, and a sealing ring 82 is fixedly provided at the lower end of the side wall of the filter body 2. The lower end of the threaded funnel 8 is conical, and a threaded cover 9 is provided at the lower end of the threaded funnel 8. A threaded groove 81 is provided on the inner side of the threaded funnel 8. The threaded funnel 8 is threadedly connected to the filter body 2. A sealing ring 82 is fixedly provided at the lower end of the side wall of the filter body 2. The lower end of the threaded funnel 8 is conical, and a threaded cover 9 is provided at the lower end of the threaded funnel 8.

Groove 2 91, threaded cover 9 is threadedly connected to the lower end opening of threaded funnel 8, and a sealing ring 2 92 is fixed in threaded cover 9. When rotating shaft 5 makes large circular hole 31 and small circular hole 32 covered, water flow cannot pass through the regulating valve. When rotating shaft 5 makes large circular hole 31 and small circular hole 32 not completely covered, water flow flows into filter body 2 from inlet 11, and then flows to outlet 13 from filter body 2. Water flow to outlet 13 is filtered by filter screen 7 in filter body 2. When rotating shaft 5 makes small circular hole 32 covered but large circular hole 31 not completely covered, threaded cover 9 is unscrewed to make water flow enter filter body 2 and impact filter screen 7 and impurities in filter body 2. If filter screen 7 needs to be replaced, rotating shaft 5 makes large circular hole 31 and small circular hole 32 covered to block water flow, and then threaded funnel 8 is removed and replaced.

[0023] Working principle: when the rotating shaft 5 is rotated so that both the large circular hole 31 and the small circular hole 32 are covered, water cannot flow through the regulating valve; when the rotating shaft 5 is rotated so that both the large circular hole 31 and the small circular hole 32 are not completely covered, water flows from the inlet 11 into the filter body 2, and then flows from the filter body 2 to the outlet 13, and the water flowing to the outlet 13 is filtered by the filter screen 7 in the filter body 2; when the rotating shaft 5 is rotated so that the small circular hole 32 is covered but the large circular hole 31 is not completely covered, the threaded cover 9 is unscrewed to allow water to flow into the filter body 2 and impact the filter screen 7 and impurities in the filter body 2; if the filter screen 7 needs to be replaced, the rotating shaft 5 is rotated so that both the large circular hole 31 and the small circular hole 32 are covered to block the water flow, and then the threaded funnel 8 is removed and replaced.
