AI Technical Summary

Technical Problem

When inspecting existing multi-layered protective ventilation ducts, the connection between the ventilation pipe and the duct body is inconvenient, resulting in low work efficiency and poor sealing, which affects measurement accuracy and energy consumption.

Method used

The design incorporates limiting and sealing components, including a telescopic rod, spring, contact block, positioning ring, sealing components, and one-way backflow plate. The spring force temporarily positions the vent pipe, and the sealing components engage with the pressure detection pipe to improve connection sealing and stability.

Benefits of technology

It improved work efficiency, enhanced the connection and sealing between the pipeline body and the vent pipe, reduced air leakage, ensured measurement accuracy, and reduced energy consumption.
