A torsion spring 43 is sleeved on the outer wall of the opening plate 42, and the other end of the torsion spring 43 is fixedly mounted on one end of the water inlet 2. The design of the torsion spring 43 is mainly to automatically reset the opening plate 42. A protective pad 44 is fixedly connected to the bottom of the opening plate 42, and the displacement trajectory of the protective pad 44 contacts the bottom of the inner wall of the valve body 1. The design of the protective pad 44 is mainly to avoid the bottom of the inner wall of the valve body 1 from being damaged due to the bottom of the opening plate 42 directly contacting the bottom of the inner wall of the valve body 1 during the rotation process.

[0020] During use, when liquid enters the interior of the valve body 1 through one end of the water inlet 2, it will first be fixed to one side of the opening plate 42 on one side of the rotating shaft 41. Because the other side of the rotating shaft 41 rotates at one end of the water inlet 2, one side of the opening plate 42 will rotate counterclockwise after being impacted by the water flow, and then the water inlet 2 will be expanded through the counterclockwise rotation of the opening plate 42. When the liquid flow ends, the elastic action of the torsion spring 43 mounted on the outer wall of the opening plate 42 will automatically drive the opening plate 42 to reset automatically and then return to the initial angle. The liquid in the inner wall of the valve body 1 is blocked by the opening plate 42, thereby preventing the accident of backflow from one end of the water inlet 2.
