AI Technical Summary
When the water flow rate in the existing municipal drainage network confluence node structure is too large, the baffles can easily lead to water flow restriction, causing drainage difficulties and pipe wall corrosion.
The design employs a dual pressure relief system with rollers and baffles, combined with elastic components and limiting structures. The rollers slide to increase the gap when the water pressure is high, while the baffles buffer the impact of the water flow to prevent the water flow from directly impacting the pipe wall. The sliding frame also slides when the water pressure is high to prevent drainage blockage.
It effectively prevents water flow from directly impacting and corroding the pipe wall, ensures smooth drainage, avoids drainage difficulties, and achieves a good pressure relief effect.
