AI Technical Summary
Long-distance water transmission and distribution pipelines are prone to leakage under water hammer conditions. Existing protective devices cannot effectively utilize water hammer energy to enhance the interface seal, leading to seal failure and leakage.
The design incorporates an interface energy transmission device and an interface energy discharge device. Water hammer energy is converted into interface air pressure to enhance sealing, and excess gas is discharged through the interface energy discharge device, thus achieving active energy capture and utilization.
It significantly improves the anti-leakage capability of pipe joints under water hammer impact, realizes dynamic adaptive adjustment of sealing force, reduces maintenance costs, and improves the safety and lifespan of pipelines.
