AI Technical Summary
In existing technologies, butterfly valves cannot achieve the positioning and fixation of pipelines while sealing, which makes pipelines prone to displacement, affecting system stability and potentially causing leaks.
A sealing and protective structure was designed, comprising a shell, a guide ring, a U-shaped ring, a pressure plate, an elastic element, a positioning ring, a spring, and a sealing assembly. The guide ring and the U-shaped ring work together to fix the pipe in place, and the sealing assembly improves the sealing performance.
While sealing, it also achieves stable positioning of the pipeline, preventing pipeline displacement, improving sealing performance, and preventing leakage.
