- 摘要:
- 根据高压氧气特殊的化学性质和高压氧气供应系统使用要求，参考航天QJ2889系列37°导管连接件标准，设计了DN4，DN10和DN20的黄铜球头、焊接直通等连接件，并进行了强度校核、强度及密封性试验。系统建设后经正式应用验证，确认黄铜连接件设计满足了高压氧气系统使用要求，解决了黄铜管路与不锈钢管路互连的技术难题。
- Abstract:
- According to the chemistry characteristics of high-pressure oxygen and its supplying system requirements, some brass balls of DN4, DN10, DN20 and straight adapting pieces were designed by referring to Chinese space industry standard QJ2889 series about the adapting piece for 37° conical surface tube. Strength assessment, strength test and encapsulation test of specimens were made. The brass tube adapting pieces were applied in the high-pressure oxygen supplying system and the result satisfied the requirements of the high-pressure oxygen system. The difficulty of connection between brass tube and stainless steel tube was solved.
