[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve used for on / off control of low-pressure pipeline media. A butterfly valve is defined as a valve whose closing element is a disc that rotates around the valve shaft to achieve opening and closing. However, existing butterfly valves are connected to the pipeline via flanges during installation, requiring multiple screws for fixation. This cumbersome process, involving repeated tightening of screws, reduces installation efficiency. Therefore, we propose a butterfly valve structure with optimized sealing performance.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 , Figure 2This utility model provides a technical solution: a butterfly valve structure with optimized sealing performance, including a butterfly valve body 1, with connecting pipes 2 at both ends of the butterfly valve body 1, and a connecting assembly between the butterfly valve body 1 and the connecting pipes 2. The connecting assembly includes fixed sleeves 3 fixed to the surfaces of both ends of the butterfly valve body 1, a fixed ring 4 fixedly connected to the surface of the connecting pipe 2, and a movable sleeve 5 provided on the side of the fixed ring 4 away from the fixed sleeve 3. The movable sleeve 5 is fitted onto the surface of the connecting pipe 2, and an external thread 6 is provided on one side of the surface of the movable sleeve 5. The inner surface of the fixed sleeve 3 is provided with an internal thread 7 that matches the external thread 6. A rotating ring 8 is fixedly fitted on the other side of the surface of the movable sleeve 5. The fixed sleeve 3, fixed ring 4, movable sleeve 5, and rotating ring 8 are all made of aluminum alloy, making the connection between the butterfly valve body 1 and the connecting pipe 2 more secure. The rotating ring 8 is fitted with an anti-slip sleeve, providing good anti-slip effect when rotated, allowing for easier rotation. When connecting the butterfly valve body 1 to the connecting pipe 2, the operator first places the butterfly valve body 1 on... The butterfly valve body 1 is positioned so that its end aligns with the end of the connecting pipe 2. Then, the movable sleeve 5 is moved along the surface of the connecting pipe 2 until its side is inside the fixed sleeve 3. The rotating ring 8 is then rotated, causing the movable sleeve 5 to rotate simultaneously. Through the interaction of the external thread 6 and the internal thread 7, the movable sleeve 5 and the fixed sleeve 3 are firmly connected. When the movable sleeve 5 reaches the appropriate position, its inner end face presses against the side of the fixed ring 4, completing the connection between the butterfly valve body 1 and the connecting pipe 2. Existing butterfly valves are installed by connecting to the connecting pipe via a flange, requiring multiple screws for fixing. This cumbersome process involves repeatedly tightening multiple screws, reducing installation efficiency. By designing a butterfly valve body 1, connecting pipe 2, and connecting components, the butterfly valve body 1 and connecting pipe 2 can be quickly connected. This simple, time-saving, and labor-saving design effectively improves installation efficiency. The compact overall structure makes it worthy of widespread adoption.

[0018] In this embodiment, preferably, please refer to... Figure 2 , Figure 3As shown, it also includes a sealing assembly, which includes a first sealing ring 9 fixed to the end of the butterfly valve body 1. A first sealing groove 10 adapted to the first sealing ring 9 is opened on the side of the connecting pipe 2 near the butterfly valve body 1. A first sealing rubber gasket 11 is provided inside the first sealing groove 10. A second sealing ring 12 is also fixedly connected to the side of the connecting pipe 2 near the butterfly valve body 1. A second sealing groove 13 adapted to the second sealing ring 12 is also opened on the end surface of the butterfly valve body 1. A second sealing rubber gasket 14 is provided inside the second sealing groove 13. The outer diameter of the first sealing ring 9 is 1.1 times that of the second sealing ring 12, ensuring that the first sealing ring 9 and the second sealing ring 12 will not touch during the connection between the butterfly valve body 1 and the connecting pipe 2. By designing the sealing components, after the butterfly valve body 1 is connected to the connecting pipe 2, the double barrier effect of the first sealing ring 9 and the first sealing rubber gasket 11, and the second sealing ring 12 and the second sealing rubber gasket 14, makes the sealing performance of the butterfly valve better after installation. Compared with the existing sealing structure, it is more optimized and ensures a stronger sealing performance of the butterfly valve after installation.
