| Abstract: | Spherical sealing joint is an important joint in the propulsion system of satellite. Its sealing ability is studied by experiments. An experiment system with puffing facility, detector and wrench is designed. The results show that the sealing performance is affected by the machining quality of the sphere surface and the cone-shape surface of the spherical sealing joint, and the assembling quality. |
