- 摘要:
- 为满足某推进分系统压力调节流量范围大、控制要求精度高、可靠性高且需满足长时间在轨使用的要求，研制了一种高精度金属膜片式气体减压阀。对该逆向卸荷金属膜片式气体减压阀的方案设计、结构特点、关键技术以及达到的技术指标进行了总结，并给出了飞行试验验证结果，经飞行试验验证，减压阀飞行工作状态良好，满足使用要求。
- Abstract:
- The pressure regulator is one of the core units in space propulsion systems. The overall scheme design, structural characteristics, key technologies and achieved qualifications of the reverse unloading pneumatic pressure regulator with metal diaphragm are summarized. The key technology breakthrough achieved in the R&D process is described. The verified results in the space flights testing indicate that the pressure regulator works well. Therefore, the research is significant for optimizing the structural parameters and reliable design of the regulator.
