[0002] Valves can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metals and radioactive media. They mainly serve to shut off and throttle in pipelines. A butterfly valve is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening, closing or regulating.

[0003] According to Chinese Patent CN202322980612.9, a butterfly valve for preventing the displacement of the sealing ring is installed in the valve body. The connecting part is inserted into the valve body, the inner side of the sealing part abuts against the outer side of the connecting sleeve, the first limiting part is engaged in the inside of the groove, and the convex ring part is engaged in the inside of the annular groove. The sealing part is fixed to the connecting sleeve by fixing screws, which ensures the stability of the sealing ring and prevents the sealing ring from rotating circumferentially under the torque force of the butterfly plate, thus improving the sealing effect. Existing butterfly valves use multiple sets of screws to limit and fix the sealing ring, which is time-consuming and laborious to disassemble and assemble the sealing ring. At the same time, the screw fixing can damage the sealing ring.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a butterfly valve for preventing the sealing ring from shifting is provided.

[0026] Example 1;

[0027] like Figure 1-6 As shown, the butterfly valve for preventing the sealing ring from shifting according to an embodiment of the present invention includes a butterfly valve body 1, a disc 2 in the butterfly valve body 1, a handle 16 on the outer wall of the butterfly valve body 1, a sealing gasket 3 on the inner wall of the butterfly valve body 1, and sealing gaskets 4 extending to the outside of the butterfly valve body 1 on both sides of the sealing gasket 3. The sealing gasket 3 and the sealing gasket 4 are fixedly connected, and clamping assemblies matching the sealing gasket 4 are provided on both sides of the butterfly valve body 1.

[0028] Example 2;

[0029] like Figure 1-6As shown, the valve includes a butterfly valve body 1, a disc 2 within the body, a handle 16 on the outer wall, a sealing gasket 3 on the inner wall, and two sealing gaskets 4 extending beyond the body on both sides of the sealing gasket 3. The sealing gasket 3 and the sealing gasket 4 are fixedly connected. Clamping assemblies matching the sealing gaskets 4 are provided on both sides of the butterfly valve body 1. An anti-slip rubber sleeve is fitted over the outer wall of the handle 16. Several evenly distributed mounting holes 5 are provided on both sides of the butterfly valve body 1. Several evenly distributed positioning blocks 6 are provided on the outer wall of the sealing gasket 3, and positioning grooves 7 matching the positioning blocks 6 are provided on the inner wall of the butterfly valve body 1. The clamping assembly includes mounting rings 8 on both sides of the butterfly valve body 1. Each mounting ring 8 has a plurality of arc-shaped pieces 9 arranged in a circumferential array on one side, with limiting grooves 10 formed between each pair of arc-shaped pieces 9. The outer wall of the sealing gasket 4 has a limiting block 11 that matches the limiting groove 10. A pressure ring 12 is fitted onto the outer wall of each arc-shaped piece 9. Both sets of mounting rings 8 are fixedly connected to the butterfly valve body 1. The outer wall of each arc-shaped piece 9 has an external thread 13, and the inner wall of the pressure ring 12 has an internal thread 14 that matches the external thread 13. An anti-slip pad 15 that matches the limiting block 11 is provided on one side of the pressure ring 12.

[0030] In practical applications, when installing the sealing gaskets, firstly, insert sealing gasket 3 into the butterfly valve body 1, so that the positioning block 6 on the outer wall of sealing gasket 3 is engaged in the positioning groove 7 on the inner wall of the butterfly valve body 1. Then, place the sealing gaskets 4 on both sides of sealing gasket 3 into the arc-shaped pieces 9 on both sides of the butterfly valve body 1, and engage the limiting block 11 on sealing gasket 4 into the limiting groove 10. Then, cover the arc-shaped piece 9 with the pressure ring 12. Since the pressure ring 12 is threadedly engaged with the arc-shaped piece 9, rotating the pressure ring 12 causes the pressure ring 12 to move on the arc-shaped piece 9. The pressure ring 12 drives the anti-slip pad 15 to squeeze the limiting block 11 and limit it. By setting the clamping assembly, sealing gasket 1 and sealing gasket 2 can be quickly fixed to prevent the sealing gasket from shifting during the use of the butterfly valve. The clamping assembly uses a set of pressure rings to squeeze and fix the sealing gasket, which is more convenient than fixing the sealing gasket with multiple sets of screws, and will not damage the sealing gasket, making it safer and more reliable.

[0031] In summary, by means of the above-mentioned technical solution of this utility model, the sealing gasket one and sealing gasket two can be quickly fixed by setting a clamping component, preventing the sealing gasket from shifting during the use of the butterfly valve. The clamping component uses a set of pressure rings to squeeze and fix the sealing gasket, eliminating the need for multiple sets of screws to fix the sealing gasket, making the operation more convenient and preventing damage to the sealing gasket, thus making it safer and more reliable.
