AI Technical Summary
In existing steam boilers, under long-term high-frequency vibration, threaded connections are prone to loosening, leading to safety hazards such as leakage and pipe detachment.
A steam boiler heat transfer device based on a multi-stage spiral flow channel is adopted. By using fixing devices and locking components, and through the snap-fit structure of toothed discs and toothed blocks, combined with the design of elastic support components and rotating discs, the pipes are firmly fixed and loosened.
It effectively prevents pipelines from loosening and leaking under high-frequency vibration, improves the stability and safety of the device, and facilitates disassembly and maintenance.
