[0002] An air duct flexible joint is a flexible connecting component specifically designed for air duct systems. It is made of high-quality materials and has good elasticity, corrosion resistance, high-temperature resistance, and sealing performance. Through its unique structural design, the air duct flexible joint can achieve flexible connection between air ducts, effectively absorb system vibration, reduce noise transmission, and allow a certain degree of axial, angular, and lateral displacement to adapt to the complex layout and dynamic changes of the air duct system. In the fields of heating, ventilation, air conditioning, ventilation, and smoke exhaust, the air duct flexible joint plays a crucial role in ensuring the stable operation and high efficiency of the air duct system.
