AI Technical Summary

⚠Technical Problem

Existing online calibrators cannot accurately measure the set pressure and sealing performance of safety valves, and pose safety hazards, especially when handling flammable and explosive media.

⚗Method used

Design an online calibrable safety valve, comprising an online calibrating unit including a switching component, a connecting pipe, a pressure detection component, and an online calibrating technology. The safety valve body is located at the valve inlet. The safety valve calibrating unit includes a switching component and a control valve. The switching component is rotatably mounted at the valve inlet. The connecting pipe passes through the safety valve body and connects to the switching component. The control valve is mounted on the connecting pipe. The switching component has a first state and a second state, realizing the on/off control of the valve inlet and the interior of the safety valve body.

🎯Benefits of technology

It enables accurate online calibration of safety valves, ensures valve seat sealing tests, avoids safety hazards from hazardous media, and improves the accuracy and efficiency of calibration.
