Our company's Automatic Butterfly Valve sealing structure uses industry-leading elastic sealing materials, including high-performance rubber and polytetrafluoroethylene (PTFE). These materials not only have excellent elasticity and wear resistance, but also can adapt to the chemical properties of a variety of media, thereby ensuring that the valve can operate stably and long-term under harsh working conditions. Especially when dealing with corrosive, high-temperature or high-pressure media, our company's sealing structure shows excellent performance and meets the needs of various industrial applications.
In the design of the sealing form, our company fully considers the special requirements of different working conditions. For general fluid control applications, our company adopts a soft sealing structure. This structure uses an elastic sealing ring to achieve sealing between the butterfly plate and the valve seat, and has significant advantages such as excellent sealing effect and small opening and closing torque, which is especially suitable for occasions with frequent opening and closing. In addition, the soft sealing structure has good self-adaptability and can automatically compensate for changes in the sealing gap caused by changes in medium pressure or temperature, ensuring that the sealing performance of the valve is consistent.
For application scenarios that require a higher sealing level or handle special media, our company uses a hard sealing structure. This structure usually adopts metal-to-metal sealing, relying on precise machining and heat treatment processes to ensure that the sealing surface between the butterfly plate and the valve seat has excellent matching and hardness. This design can withstand higher pressures and temperatures, and is not easily corroded or worn by the medium, thereby effectively extending the service life of the valve.
In addition to the careful selection of sealing materials and the optimized design of sealing forms, our company also pays special attention to the detailed processing of the sealing structure. For example, on the contact surface between the butterfly plate and the valve seat, our company uses advanced polishing technology to significantly reduce friction resistance and wear. At the same time, at the installation position of the sealing ring, our company has designed a precise guide structure to ensure that the sealing ring will not be damaged or misplaced during installation. In addition, our company has also implemented a double sealing structure, with two sealing rings set between the butterfly plate and the valve seat to further improve the sealing reliability and safety of the valve.
