AI Technical Summary
The existing connection structure between the original gas odor analyzer and the gas mass flow meter has insufficient sealing, resulting in a large deviation between the measured flow rate and the actual value. This makes it impossible to accurately verify the flow rate and affects the odor assessment by the odor analyzer.
The threaded connection structure, combined with trapezoidal stacked seals and bellows seals, enhances the sealing performance between the connectors. The positioning rod and balance tube improve the stability and sealing of the connection, reducing gas leakage.
It improves the measurement accuracy of gas mass flow meters, reduces gas leakage, ensures the reliability and accuracy of odor assessment data, and reduces installation difficulty and work efficiency.
