Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model preferred embodiment is elaborated:

Sealing surface displacement as shown in Figure 1 to 11 can detect black box 100, and it is arranged between the first flange 200 and the second method 300, mainly comprises ring body 1, main seal ring 2 and pressure sensor 4.

Wherein, ring body 1 comprises interior ring 11 and outer shroud 12. Main seal ring 2 is located between interior ring 11 and outer shroud 12, and what it adopted is O-ring seal, and its upper and lower end face forms two ends for sealing with parts to be sealed the hermetically-sealed construction contacting. Leak collection sealing ring 3 and be located on the upper and lower end face of outer shroud 12, i.e. leakage collection sealing ring 3 is positioned at radial outside or the inner side of hermetically-sealed construction. Drawing small opening 5 and mozzle 6 is all opened on outer shroud 12; Draw small opening 5 at main seal ring 2 and leak on the ring body 1 of collecting between sealing ring 3, it communicates (in the present embodiment with the axial both ends of the surface of ring body 1, what in outer shroud 12 both ends of the surface on axially, also offer respectively ring-type draws bakie 9, this draws bakie 9 collects between sealing ring 3 and the hermetically-sealed construction of main seal ring 2 leaking, and both sides draw bakie 9 all with draw small opening 5 and be connected; If leak at hermetically-sealed construction place like this, just the leak materials leaking out can through draw bakie 9 be pooled to draw in small opening 5); Mozzle 6 with draw small opening 5 and be connected, it radially extends on outer shroud 12.
