AI Technical Summary
Technical Problem
Existing safety relief valves cannot adjust the relief pressure according to different needs at any time, and the replacement of consumable parts such as springs is inconvenient.
Method used
An intelligent induction-type safety relief valve was designed. It detects the gas flow rate through a flow meter and automatically adjusts the relief pressure using the cooperation of a return spring and an electric actuator. The return spring can be easily replaced by separating the valve body and valve cover.
Benefits of technology
It enables real-time adjustment of the venting pressure based on flow rate, improves the level of automation, simplifies the replacement process of consumable parts, and ensures the effectiveness of the venting valve.
