Abstract: The high temperature valve installed on the high temperature flue gas pipe from 800 ℃ to 1 000 ℃ is the core component of thermal energy control in the heating process of low concentration gas thermal storage and oxidation shaft, in order to meet the technical requirements of low failure rate and small leakage, the material and structure requirements of high temperature valve were analyzed. It is concluded that high temperature valve should be made of superalloy steel as the main material, stainless steel surfacing alloy as the internal material, Wood sealing structure and appropriate casting process. The developed high temperature valve has good operation effect in the actual heating process of Xiaonanzhuang gas thermal storage oxidation shaft in Yangquan No.5 Coal Mine, which can meet the performance requirements of process thermal energy regulation, and improve the economy and safety of the project process.
