AI Technical Summary

Technical Problem

Existing packing structures do not provide good sealing performance under small molecule gases, toxic and harmful gases, and high pressure conditions, posing a risk of leakage and making it difficult to meet the sealing requirements of miniaturized equipment.

Method used

The system employs a combined packing structure, including a throttling ring assembly, a main sealing ring assembly, and a nitrogen-filled leak-proof sealing ring assembly. The throttling ring assembly reduces pressure, the main sealing ring assembly seals the conveying gas, and the nitrogen-filled leak-proof sealing ring assembly recovers leaked gas. Combined with PEEK polyether ether ketone material and a tension spring structure, the system enhances sealing performance and safety.

Benefits of technology

It achieves effective sealing under high pressure and small molecule gas conditions, prevents leakage of toxic and harmful gases, ensures safe production, and improves sealing reliability by controlling temperature through circulating cooling.
