摘要
文章阐述了太阳成像仪镜筒舱内压力控制技术研究,主要包括限流小孔机械尺寸理论分析、慢速泄压阀设计、镜筒压力控制模拟测试等内容。目前,所研制的慢速泄压阀已顺利交付使用,并随46.5 nm极紫外太阳成像仪在中科院空间新技术试验卫星上进行了搭载,实现了在轨顺利开机,验证了太阳成像仪镜筒舱内压力控制手段的正确性。
The paper introduces the research on the pressure control technology in the mirror chamber of solar imager,including theoretical analysis of mechanical dimensions of current-limiting orifice,design of valve for slow pressure relief,and pressure control simulation test of mirror chamber.At present,the developed slow pressure relief valve has been successfully delivered and put into use with the 46.5 nm extreme ultraviolet solar imager carried out on the Chinese Academy of Sciences’Space New Technology Experiment Satellite.
