摘　　要：在稠油热采井口装置中,介质的温度达到370℃,压力达到21MPa,常温平行闸阀的密封结构和密封材料已无法满足使用要求。从密封结构、密封机理和受力角度3个方面对现有热采平行闸阀的现状进行了分析和比较,并对高温工况下密封的难点和未来研究方向进行了分析,供从事热采井口闸阀和相关产品的设计、制造人员参考。For heavy oil thermal recovery wellhead,medium temperature reaches 370 ℃ ,the pres- sure reaches 21 MPa,room temperature parallel gate valve seal structure and sealing materials has been unable to meet the requirements. From the seal structure, sealing mechanism and the force angle, status analysis and comparison were made for thermal recovery of parallel gate valve, and the analysis of sealed difficulties of high-temperature operating conditions, and future research di- rections as well. This can be used as reference for heating wellhead gate valves and related prod- ucts design, and manufacturing.
