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。
According to the special chemical properties of high pressure oxygen and high pressure oxygen supply system requirements, reference space QJ2889 series 37. Conduit connector standard, the design of the DN4, DN10 and DN20 brass ball head, straight through the connection such as welding, and conducted a strength check, strength and tightness test. After the system was formally verified by the system construction, the design of the brass connector was confirmed to meet the requirements of the high-pressure oxygen system and the technical problems of interconnecting the brass pipe and the stainless steel pipe were solved.
