AI Technical Summary

Technical Problem

Traditional gate valves cannot dynamically adjust their sealing structure under complex operating conditions, leading to a decline in sealing performance. Furthermore, the lack of comprehensive sealing status monitoring results in a high risk of leakage, especially in corrosive media environments where the risk of leakage increases significantly.

Method used

The self-compensating sealing control component integrates parameter acquisition, signal preprocessing, master control decision-making, electronic control execution, and feedback verification modules. It monitors seal wear, media characteristics, and environmental conditions through multi-dimensional sensors, calculates the seal compensation amount using a fuzzy PID algorithm, and dynamically adjusts the seal pressure and displacement through an electric actuator and a micro air pump to achieve closed-loop control.

Benefits of technology

It effectively reduces leakage risk, extends service life, adapts to complex working conditions, improves sealing performance and operational stability, and reduces maintenance costs.
