90 degree flange rotary joint

In industrial pipeline systems, rotary joints are key components responsible for achieving stable transmission of fluid media between fixed pipelines and rotating equipment. However, traditional rotary joints often face problems such as high friction loss, unstable sealing performance, and short service life under right angle rotation conditions. To effectively address these industry pain points, we are pleased to introduce our independently patented 90 degree elbow flange rotary joint. With its groundbreaking technological innovation, it has achieved remarkable results in reducing friction losses during right angle rotation and extending equipment life.

Unique right angle rotation design
This rotary joint adopts a brand new right angle rotation structure, cleverly utilizing a transmission mechanism similar to worm gear or helical bevel gear (spiral bevel gear), to achieve efficient and stable power transmission between two mutually perpendicular axes. In the worm gear transmission mode, the worm (a cylindrical component similar to a thread) meshes precisely with the worm wheel (a disc-shaped component with a toothed surface). When the worm rotates, it drives the worm wheel to rotate synchronously through precise friction, thereby driving the connected pipeline to achieve right angle rotation. This design not only ensures the smoothness of the rotation motion, but more importantly, compared to the traditional direct friction method, it significantly reduces the friction loss during the right angle rotation process. Through authoritative testing and verification, compared with similar products in the market, the right angle rotation friction loss of this rotary joint has been reduced by up to 70%, greatly reducing energy waste and lowering long-term operating costs for enterprises.

Patent sealing structure ensures excellent sealing performance
Multi level sealing components work together: The joint is equipped with multiple levels of sealing components, from inside to outside, including high-precision mechanical sealing rings, high-performance rubber sealing gaskets, and specially designed graphite sealing fillers. The mechanical seal ring is made of advanced silicon carbide material, which has extremely high hardness and wear resistance, and can maintain stable sealing performance in high-speed rotation and high-pressure environments, effectively blocking the leakage of fluid media. Rubber sealing gaskets utilize their excellent flexibility and elasticity to tightly adhere to the gaps at pipeline connections, further enhancing the sealing effect, while also providing cushioning protection for mechanical sealing rings and extending their service life. The outermost graphite sealing filler, with its excellent high temperature resistance, corrosion resistance, and good self-lubricating performance, reduces the friction coefficient between sealing components while preventing external impurities from entering, ensuring the efficient and stable operation of the entire sealing system.
Dynamic adaptive sealing adjustment mechanism: To cope with changes in sealing clearance caused by equipment vibration, pressure fluctuations, and other factors during rotation, we innovatively designed a dynamic adaptive sealing adjustment mechanism. This mechanism monitors the pressure changes inside the sealed chamber in real time through a built-in pressure sensor. Once abnormal pressure fluctuations are detected, the automatic adjustment system is immediately triggered. The regulating system adjusts the clamping force of the sealing components to maintain the optimal sealing gap, ensuring excellent sealing performance under various complex working conditions, effectively avoiding the risk of leakage caused by sealing failure, and ensuring the safe and stable operation of industrial production.
