Embodiment
The electric penetrator of ceramic welding, comprise metallic conductor 4, it also comprises ceramics insulator 5, metal adpting flange 6, described metal adpting flange 6 is separated medium and atmosphere, metallic conductor 4 runs through metal adpting flange 6, metallic conductor 4 and metal adpting flange 6 through part metallic conductor 4 overcoat ceramics insulators 5, and metal adpting flange 6 atmospheric sides are provided with pressure monitoring device 8.
The electric penetrator of ceramic welding is arranged between side medium power cable 1 and atmospheric side power cable 2, plays the effect of separating atmosphere and medium, can effectively avoid medium to large gas leakage simultaneously, and atmospheric side power cable 2 connects power-on box 3.In the electric penetrator of ceramic welding, by metal adpting flange 5, cut off medium and atmosphere, metallic conductor 4 is the power supply of medium motor internal through metal adpting flange, ceramics insulator 5 and the metal adpting flange 6 of metallic conductor 4 overcoats seal 7 by ceramic welding, realize the sealing to interior media.Metal adpting flange 6 atmospheric side setting pressure monitoring devices 8, if any dielectric leakage, can improve warning message in time.
As shown in Figure 4, between metal adpting flange 6 and ceramics insulator 5, commissure is designed with special bevel for welding structure, the ceramic surface of conductor diameter processes structure as shown in Figure 2 simultaneously, when discharging sweating heat stress when guaranteeing metal adpting flange and ceramics insulator assembly welding, can guarantee the electric positiver sealing of seal nipple under cold cycling operating mode that run through.
As shown in Figure 2, for preventing that medium from leaking from middle pressure monitoring cavity and metal adpting flange 6 ends, the hermetically-sealed construction of the present invention's design is that flange face contacts with flange face, middle mounting O-shaped rings, metal wound gasket or general stopper ring, adopt double-screw bolt or bolted, with ordinary couplings comparison, this kind of structure when guaranteeing electric power transfer, reached the sealing function to gas.
