摘要（英）：

The invention provides an electric initiating explosive device sealing part for a high pressure-bearing aerospace propulsion unit. The electric initiating explosive device sealing part comprises a sealing part shell, a glass tube and a metal pin, wherein the sealing part shell is prepared by adopting a high-temperature alloy GH4169; the sealing part shell, the glass tube and the metal pin are sintered together under inert atmosphere protection; sintering process requirements are as follows: the inert gas adopts nitrogen with the purity of 99.999%, the sintering temperature is 970-1030 DEG C, and the temperature is maintained for 15-35 minutes after sintering. The electric initiating explosive device sealing part disclosed by the invention is simple in structure, the production process is simple, and the product has excellent overall properties such as pressure-bearing airtightness and the like.
