And reinforcing ribs are arranged on the inner side of the sealing ring groove of the metal pressure-resistant flange 2 to provide the pressure-resistant capability of the metal pressure-resistant flange 2. The reinforcing rib is provided with a plurality of threaded holes for fixing the internal electronic components.
Four bosses 8 with threaded holes are machined in the circumferential direction of the metal pressure-resistant flange 2 and used for mounting and positioning the electronic cabin; and the length of the threaded hole in the boss 8 is smaller than that of the boss, so that the compressive strength of the metal compressive flange 2 is prevented from being damaged.
