When the valve needs to be closed, the opening and closing member 2 is reversed to make the opening and closing member 2 reclose the valve body 1, thereby preventing the water flow from passing. When the sediment in the water flow adheres to the inner wall of the water passage 3, the twisting ring 31 is twisted to rotate the twisting ring 31, and the pressure block 33 is driven to rotate synchronously. When the pressure block 33 moves to the outer convex ball 34, the outer convex ball 34 can be pressed to squeeze the elastic tube 32 to be concave and deformed inwardly. At this time, the twisting ring 31 is continuously twisted to make the pressure block 33 pass through the outer convex ball 34. At this time, the elasticity of the elastic tube 32 can be used to quickly restore, and in the process of continuously twisting the twisting ring 31, the elastic tube 32 is repeatedly concave and restored to generate a swing, thereby loosening and shaking off the sediment attached to the inner wall of the elastic tube 32, and cooperating with the impact of the water flow to wash away the attached sediment, so that the valve is not easy to be blocked, and the cleaning of the valve is more convenient and quick;

[0020] The top of the opening and closing member 2 is also provided with a twisting handle 5, which is conducive to making the opening and closing of the opening and closing member 2 more convenient and the force transmission smoother;

[0021] The water passage 3 is also provided with a connecting flange 4 at one end away from the valve body 1, which is conducive to making the connection of external pipe fittings more convenient and quick;

[0022] The outer wall of the twisting ring 31 is provided with a plurality of anti-sliding blocks 36. In this embodiment, forty anti-sliding blocks 36 are provided, which is beneficial to greatly increase the friction between the hand and the twisting ring 31 to avoid slipping during twisting;

[0023] The elastic tube 32 is embedded with a plurality of twisting columns, and six are provided in this embodiment, which is conducive to enabling the elastic tube 32 to produce a greater deformation, thereby obtaining a better mud and sand cleaning effect;

[0024] The inner wall of the elastic tube 32 is also provided with a plurality of vibration blocks 35. In this embodiment, six vibration blocks 35 are provided. The vibration blocks 35 include a fixed sheet 41 provided on the inner wall of the elastic tube 32 and an elastic swinging sheet 42 provided on the fixed sheet 41. When the elastic tube 32 swings, the fixed sheet 41 and the elastic swinging sheet 42 also swing at the same time. Since the elastic swinging sheet 42 has a certain elasticity, it will repeatedly hit the attached mud and sand during the swinging process, thereby making the attached mud and sand looser and easier to fall off.

[0025] A cavity is formed between the fixed plate 41 and the elastic swing plate 42, and a plurality of freely rolling impact balls 43 are arranged in the cavity. In this embodiment, three impact balls 43 are arranged, which is beneficial for the impact balls 43 to repeatedly impact the elastic swing plate 42 during the swinging process, thereby increasing the vibration impact of the elastic swing plate 42 on the attached mud and sand, making it easier to fall off the attached mud and sand.

[0026] Working principle of the utility model: When the utility model is used, the water passage 3 of the valve body 1 is connected to the external pipe fitting, and the water can flow into the water passage 3. When the valve needs to be opened, the opening and closing member 2 is twisted to make it lose the closed valve body 1, so that the water can pass through the valve body 1 and flow to the other side. When the valve needs to be closed, the opening and closing member 2 is reversed to make the opening and closing member 2 re-close the valve body 1, thereby preventing the water from passing. When the mud and sand in the water flow adhere to the inner wall of the water passage 3, the twisting ring 31 is twisted to rotate the twisting ring 31 and synchronously drive the pressure block 3 3, when the pressure block 33 moves to the outer convex ball 34, the outer convex ball 34 can be pressed to squeeze the elastic tube 32 to be concave and deformed inwardly. At this time, the twisting ring 31 is continuously twisted to make the pressure block 33 pass through the outer convex ball 34. At this time, the elasticity of the elastic tube 32 can be used to quickly restore, and in the process of continuously twisting the twisting ring 31, the elastic tube 32 is repeatedly concave and restored to generate swing, thereby loosening and shaking off the mud and sand attached to the inner wall of the elastic tube 32, and cooperating with the impact of water flow to wash away the attached mud and sand, so that the valve is not easily blocked and the valve cleaning is more convenient and quick.
