AI Technical Summary
Existing gas pipeline connections are prone to loosening, resulting in loose connections, corrosion spots, and inconvenient maintenance.
The system employs a combination of plug-in rings and threaded connecting rings, combined with silicone rubber plug-in rings and a nano-composite coating to enhance the connection sealing performance. It uses an annular airbag and a pressure sensor to control the sealing effect, and optimizes the operation of the air pump through a PID algorithm to form a closed-loop sealing system.
It improves the sealing effect of gas pipeline connections, prevents leakage and corrosion, and enables quick connection and disassembly for easy maintenance.
