AI Technical Summary

Technical Problem

The metal material of existing compressor valve plates leads to rapid heat transfer, high noise, and poor sealing performance, which affects refrigeration efficiency and valve plate reliability.

Method used

The valve plate adopts an embedded design with an embedded opening on the valve plate body. The embedded part is made of engineering plastic and forms a "sandwich" structure through protrusions and grooves. Combined with the limiting claw, it achieves sealing and heat insulation. The embedded part is made of polyetheretherketone material to reduce noise and absorb impact loads.

Benefits of technology

It improves the sealing performance at the interface between metal and engineering plastic, reduces heat transfer, lowers noise, extends valve life, and enhances refrigeration efficiency and energy efficiency.
