[0002] The handle butterfly valve has a simple structure, small size, and light weight, consisting of only a few parts.

[0003] When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop generated by the valve is very small, thus it has good flow control characteristics. The defects of the existing butterfly valve process are: the product needs to be reassembled, which may increase the time and generate secondary assembly costs. If the assembly is not secure, it will increase the probability of product leakage. It cannot be assembled in one go, which increases the time cost of using the equipment.

[0025] Example 1: A butterfly valve with a clamp handle, such as Figures 1-4 As shown, the device includes a bushing 7 and a clamping connector 8 inserted into the bushing 7. A clamping auxiliary connector 10 is fixedly connected to one side of the clamping connector 8, and the clamping auxiliary connector 10 is inserted into the bushing 7. A valve shaft 6 is inserted into the upper end of the bushing 7, extending out of one side of the bushing 7 and inserted into the clamping connector 8. A support handle 1 is provided above the bushing 7, used to support the device's operation. When the device is running, the clamping auxiliary connectors 10 and clamping connector 8 on both sides are fixedly connected by the connection support of the bushing 7, thus achieving the connection between the clamping auxiliary connector 10 inside the bushing 7 and the clamping connector 8. The protective effect of the clamp joint 8 ensures stable flow sealing inside the clamp auxiliary joint 10 and clamp joint 8. By setting the valve shaft 6 to simultaneously insert with the bushing 7 and clamp joint 8, the stability and sealing integrity of the device during use are guaranteed. The clamp connection method strengthens and widens the device connection, making it easy to install firmly. Furthermore, the cooperation of multiple components eliminates the need for secondary assembly, shortening time and saving costs. This product is assembled in one piece at the original factory, reducing the probability of leakage during secondary assembly.

[0026] like Figures 1-4 As shown, fastening flanges 9 are provided on both sides of the bushing 7. The fastening flanges 9 are threadedly connected to the clamp auxiliary joint 10. The clamp joint 8 is threadedly connected to the fastening flanges 9. A sealing support ring 11 is fixedly connected to the outside of the clamp auxiliary joint 10. The sealing support ring 11 is located on one side of the fastening flanges 9. By rotating the two fastening flanges 9 and with the thread support of the clamp auxiliary joints 10 and clamp joint 8, the stability of rotating the two fastening flanges 9 can be improved, thereby ensuring the reliable position fastening of the bushing 7.

[0027] like Figures 1-4As shown, a sealing auxiliary ring 12 is fixedly connected to the outside of the clamp joint 8, and two fastening flanges 9 are located between the sealing support ring 11 and the sealing auxiliary ring 12. By placing the two fastening flanges 9 between the sealing support ring 11 and the sealing auxiliary ring 12, the stability of the device when connecting to the outer connecting parts is ensured, as well as the reliability of the fixed distance in the middle of the device is ensured.

[0028] Example 2: A butterfly valve with a clamp handle, such as Figures 1-4 As shown, an auxiliary handle 2 is rotatably mounted below the support handle 1. A reset support block 3 is provided between the support handle 1 and the auxiliary handle 2. The reset support block 3 is used for the springback of the auxiliary handle 2. A height connecting frame 4 is fixedly connected to one end of the support handle 1. The height connecting frame 4 is rotatably connected to the auxiliary handle 2. By holding the support handle 1 and pressing the auxiliary handle 2 with the support of the height connecting frame 4, the effect of moving and closing a component is achieved. With the elastic support of the reset support block 3 itself, the auxiliary handle 2 can be automatically reset.

[0029] like Figures 1-4 As shown, several limiting flanges 5 are fixedly connected to the lower end of the height connecting frame 4. The height connecting frame 4 is fixedly connected to the valve shaft 6. The valve shaft 6 is located between the several limiting flanges 5. By setting the valve shaft 6 between multiple limiting flanges 5, the rotation of the height connecting frame 4 can be limited by the limiting flanges 5, ensuring the stability when it drives the valve shaft 6 to move.

[0030] Working principle: By supporting the bushing 7, the auxiliary clamp joints 10 and clamp joints 8 on both sides are fixedly connected, achieving the effect of protecting the connection between the auxiliary clamp joints 10 and clamp joints 8 inside the bushing 7. This ensures stable flow sealing inside the auxiliary clamp joints 10 and clamp joints 8. Furthermore, by setting the valve shaft 6 to simultaneously insert with the bushing 7 and clamp joints 8, the stability and sealing integrity of the device during interlocking are guaranteed. The device connection method is set to a clamp-type connection to strengthen and widen the connection, making it easy to install firmly. With the cooperation of multiple components, the product does not require secondary assembly, shortening time and saving costs. This product is assembled in one piece at the original factory, reducing the probability of leakage during secondary assembly. Moreover, by rotating the fastening flanges 9 on both sides and with the thread support of the auxiliary clamp joints 10 and clamp joints 8 on both sides, the stability of rotating the two fastening flanges 9 can be improved, thereby ensuring a reliable positional fastening of the bushing 7.
