[0019] The following is a further detailed description of the implementation of the utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Combination Figure 1 , Figure 2 and Figure 3As shown, a clamp butterfly valve includes a valve body 1, the valve body 1 includes a clamp 2, an adjustment component 3 and a sealing component 4, the clamp 2 is used to connect the pipeline; the adjustment component 3 is used to adjust the flow of the medium inside the clamp 2; the sealing component 4 is used to ensure the sealing safety when adjusting the flow of the medium inside the clamp 2. Specifically, the clamp butterfly valve is an important fluid control device, and its design and function ensure the safety and effective operation of the pipeline system. The valve body 1 is the main structure of the butterfly valve, which is usually made of metal material and is used to withstand the pressure and temperature of the medium in the pipeline. It is designed with a channel inside to allow the medium to pass through, and an opening is provided at a specific position so that the closure (usually as part of the adjustment component) can rotate to control the flow of the medium. The clamp 2 is an important component of the clamp butterfly valve and is mainly used to connect the pipeline. Its design allows the valve body to be quickly and easily installed on the pipeline system while ensuring the sealing and stability of the connection. The clamp 2 is usually fixed to the pipeline by bolts or other fasteners to ensure a tight connection between the valve body and the pipeline. The adjustment component 3 is mainly used to adjust the flow of the medium inside the clamp 2. This component usually includes a rotatable closure that can rotate inside the valve body 1 to change the size of the opening through which the medium passes, thereby controlling the flow rate. The adjustment component 3 may also include an operating handle, gears or other drive mechanisms to facilitate manual or automatic operation of the rotation of the closure. The sealing component 4 is used to ensure the sealing and safety of the valve when adjusting the flow of the medium inside the clamp 2. It usually includes a valve seat 6 and sealing materials, which are designed to fit tightly with the closure to prevent the medium from leaking when the valve is closed. The performance of the sealing component 4 directly affects the working effect and safety of the valve. Therefore, factors such as the nature, temperature and pressure of the medium need to be considered when selecting and using sealing materials. In general, the clamp butterfly valve achieves effective control and safe sealing of the medium flow in the pipeline through its unique clamp 2 design, adjustment component 3 and sealing component 4. In industrial fields such as chemical, petroleum, and water treatment, this valve is widely used and is of great significance for ensuring the normal operation and safety of the pipeline system.

[0021] Combination Figure 2 , Figure 3 and Figure 4As shown, the regulating assembly 3 includes a sleeve 5 sleeved on the clamp 2, a valve seat 6 is arranged on the sleeve 5, and a rotating hand wheel 7 is arranged on one side of the valve seat 6. Specifically, the regulating assembly 3 is a key part for controlling the flow of the medium, and its design directly affects the working efficiency and performance of the butterfly valve. The regulating assembly 3 includes a sleeve 5 sleeved on the clamp 2. The sleeve 5 is a supporting and connecting structure, which is firmly installed on the clamp 2, not only providing a stable supporting force, but also ensuring the close fit between the regulating assembly 3 and the valve body 1. The sleeve 5 is provided with a valve seat 6, which is an important component for realizing the sealing function in the butterfly valve. A sealing surface is formed between the valve seat 6 and the closure member. When the closure member is rotated to the closed position, the valve seat 6 ensures that the medium will not leak from both sides of the valve. The design and material selection of the valve seat 6 are crucial to the sealing performance of the butterfly valve. It needs to be able to withstand the pressure, temperature and chemical properties of the medium and maintain a long-term sealing effect. A rotating hand wheel 7 is arranged on one side of the valve seat 6. The rotating hand wheel 7 serves as an operating mechanism, allowing the operator to manually adjust the rotation angle of the closure, thereby controlling the flow of the medium. By rotating the hand wheel 7, the operator can easily adjust the opening of the butterfly valve to adapt to different working conditions. In summary, the adjustment component 3 achieves precise regulation and effective sealing of the medium flow through the coordinated work of the sleeve 5, the valve seat 6 and the rotating hand wheel 7. This design not only improves the working efficiency and reliability of the butterfly valve, but also makes the operation of the butterfly valve more convenient and flexible. In practical applications, this butterfly valve can meet the needs of various complex working conditions, providing important support and guarantee for industrial production and fluid control fields.

[0022] Combination Figure 1 , Figure 2 and Figure 3As shown, the sealing assembly 4 includes a valve stem 41 installed inside the sleeve 5, one end of the valve stem 41 is connected with the rotating hand wheel 7, and the other end of the valve stem 41 is provided with a butterfly plate 42, which is connected with the clamp 2. Specifically, the sealing assembly 4 plays a vital role in the clamp butterfly valve, ensuring the sealing and safety of the valve when adjusting the medium flow. The sealing assembly 4 mainly includes a valve stem 41 installed inside the sleeve 5. The valve stem 41, as a key component connecting the rotating hand wheel 7 and the butterfly plate 42, plays a role in transmitting power and motion. One end of it is connected with the rotating hand wheel 7, so that the operator can drive the rotation of the valve stem 41 by rotating the hand wheel 7. The other end of the valve stem 41 is provided with a butterfly plate 42. The butterfly plate 42 is the main component for adjusting the medium flow, and its shape is usually disc-shaped and can rotate in the valve body 1. When the valve stem 41 rotates, it drives the butterfly plate 42 to perform corresponding rotational motion. The butterfly plate 42 is connected with the clamp 2 to ensure that the butterfly plate 42 can stably maintain its position in the valve body 1 when it rotates, and form an effective sealing match with the valve seat 6. The design of the sealing component 4 takes into account the dual needs of medium flow regulation and sealing. On the one hand, by rotating the hand wheel 7 and driving the valve stem 41, the butterfly plate 42 can easily adjust the opening size to control the flow of the medium. On the other hand, the close fit between the butterfly plate 42 and the valve seat 6 ensures good sealing of the valve in the closed state to prevent medium leakage. In addition, the material selection of the sealing component 4 is also very important. It needs to be able to withstand the corrosion and wear of the medium and maintain long-term stability and reliability. Common materials include stainless steel, alloys, etc., which have good mechanical properties and corrosion resistance and are suitable for various harsh working environments. In summary, the sealing component 4 achieves precise regulation and effective sealing of the medium flow through the coordinated work of the valve stem 41, butterfly plate 42 and other components. It plays a vital role in the clamp butterfly valve and provides reliable support and guarantee for industrial production and fluid control fields.

[0023] Combination Figure 1 and Figure 2As shown, the sleeve 5 is an integrally formed casting, one end of the sleeve 5 is a round tube structure sleeved on the outside of the clamp 2, and the other end of the sleeve 5 is a hollow column structure and is fixedly connected to the valve seat 6 by bolts. Specifically, this design makes the sleeve 5 a component with a solid structure and clear functions, which plays a key role in the overall performance and stability of the butterfly valve. The sleeve 5 is an integrally formed casting, which means that it is formed in a single casting process without welding or other connection methods. This integrally formed structure not only improves the strength and durability of the sleeve 5, but also reduces potential leakage points, thereby enhancing the sealing performance of the valve. One end of the sleeve 5 is designed as a round tube structure, which is sleeved on the outside of the clamp 2. This design ensures a close fit between the sleeve 5 and the clamp 2, while providing sufficient support and stability. The round tube structure also allows the medium to flow smoothly inside the valve, reducing fluid resistance and energy loss. The other end of the sleeve 5 is a hollow column structure, which provides installation space for other components (such as the valve stem 41). The sleeve 5 is fixedly connected to the valve seat 6 by bolts, ensuring the stability and sealing of the valve seat 6. This connection method is simple, reliable, and easy to install and maintain. In summary, as an important component of the clamp butterfly valve, the sleeve 5 has the characteristics of an integrally formed casting design, a round tube structure sleeved on the outside of the clamp 2, and a hollow column structure fixedly connected to the valve seat 6 by bolts, which all reflect its advantages in enhancing the structural strength of the valve, improving the sealing performance, and facilitating installation and maintenance. Such a design helps to ensure that the clamp butterfly valve can operate stably and reliably under various working conditions.

[0024] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the outer diameter of the butterfly plate 42 is equal to the inner diameter of the clamp 2. Specifically, the butterfly plate 42 is a key component of the clamp butterfly valve, and its design has an important impact on the performance and sealing effect of the valve. According to the information you provided, the outer diameter of the butterfly plate 42 is equal to the inner diameter of the clamp 2. First, the outer diameter of the butterfly plate 42 is equal to the inner diameter of the clamp 2, which ensures that the butterfly plate 42 can fit tightly on the inner wall of the clamp 2 during rotation. This tight fit helps to reduce the leakage of the medium when the valve is closed and improve the sealing performance of the valve. Secondly, this design makes the butterfly plate 42 less resistant during rotation, thereby improving the response speed and adjustment accuracy of the valve. Since the gap between the butterfly plate 42 and the clamp 2 is extremely small, the flow resistance of the medium when flowing through the valve is also reduced accordingly, which is conducive to reducing energy consumption and improving system efficiency. In addition, this matching design of the butterfly plate 42 and the clamp 2 also enhances the structural stability of the valve. When the valve is working, the butterfly plate 42 is subjected to the pressure and impact force of the medium, but because its outer diameter is equal to the inner diameter of the clamp 2, it can better disperse these forces and reduce stress concentration, thereby improving the durability and reliability of the valve. Finally, this design is also conducive to the installation and maintenance of the valve. Since the matching relationship between the butterfly plate 42 and the clamp 2 is clear, it is easier to achieve precise alignment during installation, reducing the difficulty and time of installation. At the same time, during the maintenance process, this design also facilitates the inspection and cleaning of the inside of the valve, improving maintenance efficiency. In summary, the outer diameter of the butterfly plate 42 is equal to the inner diameter of the clamp 2, which is an optimized design choice, which helps to improve the sealing performance, response speed, adjustment accuracy and structural stability of the clamp butterfly valve, while reducing the difficulty of installation and maintenance. This design enables the clamp butterfly valve to perform excellent performance under various working conditions, meeting the needs of industrial production and fluid control fields.

[0025] Combination Figure 1 , Figure 2 and Figure 3As shown, the valve stem 41 passes through the clamp 2 and is sleeved with a rotating member 43 on the outer side in contact with the clamp 2. Specifically, the valve stem 41 passes through the clamp 2 and is sleeved with a rotating member 43 on the outer side in contact with the clamp 2. This design plays a key role in the clamp butterfly valve and further improves the performance and reliability of the valve. First, the design of the valve stem 41 passing through the clamp 2 ensures the stability of the valve and the smoothness of operation. As a key component connecting the rotating handwheel 7 and the butterfly plate 42, the valve stem needs to be able to stably pass through the clamp 2 and be able to rotate flexibly. This design enables the valve stem 41 to be firmly fixed inside the valve, while being able to smoothly transmit the rotational force, thereby achieving precise control of the butterfly plate 42. Secondly, the setting of the rotating member 43 further enhances the connection stability and rotation flexibility between the valve stem 41 and the clamp 2. The rotating member is usually made of wear-resistant and corrosion-resistant materials, which can reduce the friction between the valve stem 41 and the clamp 2, reduce wear, and extend the service life of the valve. At the same time, the rotating member 43 can also ensure the stability of the valve stem 41 during the rotation process, prevent it from shaking or offsetting, thereby ensuring the sealing and adjustment accuracy of the valve. In addition, the design of the rotating member 43 also takes into account the maintenance and maintenance of the valve. Since the rotating member 43 can be disassembled and replaced separately, when the valve needs to be repaired, the rotating member 43 can be easily disassembled for inspection and replacement, reducing the difficulty and cost of maintenance. In summary, the design in which the valve stem 41 passes through the clamp 2 and the rotating member 43 is sleeved on the outside not only enhances the structural stability and operational flexibility of the clamp butterfly valve, but also improves the sealing and adjustment accuracy of the valve, while facilitating the maintenance and maintenance of the valve. This design enables the clamp butterfly valve to better adapt to various complex working conditions and provides a more reliable and efficient solution for the field of fluid control.

[0026] Combination Figure 1 , Figure 2 and Figure 3As shown, the valve seat 6 is provided with a mounting cover 8. Specifically, in the design of the clamp butterfly valve, the mounting cover 8 on the valve seat 6 is an important detail, which plays a key role in the overall performance and function of the valve. First, the main function of the mounting cover 8 is to protect the valve seat 6 and its internal sealing structure. The valve seat is a key component responsible for sealing in the butterfly valve, and the mounting cover 8 can provide an additional protective layer to prevent the medium from directly impacting the valve seat, reduce the wear and corrosion of the valve seat 6, and thus extend the service life of the valve. Secondly, the mounting cover 8 can also serve as a support and fixing structure for the valve seat 6. During the installation process, the mounting cover 8 can ensure the accurate installation position of the valve seat 6 to prevent it from moving or misaligning. At the same time, the mounting cover 8 can also enhance the stability of the valve seat 6, so that it can maintain stable sealing performance during the operation of the valve. In addition, the mounting cover 8 can also facilitate the maintenance and overhaul of the valve. When the valve seat 6 needs to be inspected and replaced, the mounting cover 8 can be easily removed to quickly access the valve seat 6 and its related components. This design reduces the difficulty and cost of maintenance and improves the efficiency of the valve. Finally, the material selection of the mounting cover 8 is also very important. It needs to be able to withstand the corrosion and wear of the medium, and at the same time have a certain strength and toughness to ensure its long-term stability and reliability. Common materials include stainless steel, alloys, etc. These materials have good mechanical properties and corrosion resistance and are suitable for various harsh working environments. In summary, the installation cover 8 on the valve seat 6 is an important detail in the design of the clamp butterfly valve. It can not only protect the valve seat 6, improve the sealing performance and service life of the valve, but also facilitate the maintenance and overhaul of the valve. This design makes the clamp butterfly valve more reliable, efficient and easy to maintain in practical applications.

[0027] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the two ends of the clamp 2 are fixedly connected with a pipe interface 9. Specifically, in the design of the clamp butterfly valve, the two ends of the clamp 2 are fixedly connected with a pipe interface 9, and this design is crucial to the overall function and installation of the valve. First, the main function of the pipe interface 9 is to connect the clamp 2 with the pipeline system to ensure that the medium can pass through the valve smoothly. Through the fixed connection method, the pipe interface 9 can be firmly fixed at both ends of the clamp 2 to form a stable connection structure to prevent the medium from leaking during the flow process. Secondly, this design also takes into account the convenience and reliability of installation. Since the pipe interface 9 is directly fixedly connected to the clamp 2, during the installation process, it is only necessary to dock and fix the pipe interface 9 with the pipeline system to achieve rapid installation of the valve. This installation method not only simplifies the installation steps, but also improves the installation efficiency and reduces the installation cost. In addition, the material and structural design of the pipe interface 9 are also very important. It needs to be able to withstand the corrosion and wear of the medium, and at the same time have a certain strength and toughness to ensure its long-term stability and reliability. Usually, the pipe interface 9 will adopt a material that matches the pipeline system, such as stainless steel, carbon steel, etc., and the structure will be optimized according to the actual working conditions to improve its durability and sealing performance. Finally, it is worth noting that during the installation process, it is necessary to ensure that the pipe interface 9 is accurately and tightly connected to the pipeline system, and use appropriate sealing materials and fasteners to fix and seal to prevent medium leakage and ensure the normal operation of the valve. In summary, the design of fixedly connecting the pipe interface 9 at both ends of the clamp 2 makes the clamp butterfly valve more convenient, reliable and efficient during installation and use, and provides a high-quality solution for the field of fluid control.
