Inclined-plane is enclosed, capsul includes externally-located and top end opening housing and the turn in the opening of housing, Sealing shield ring
On sealing ring inclined-plane and capsul surface of shell or another Sealing shield ring on sealing ring contact of incline plane.
The improvement of technical solutions of the utility model is further used as, turn includes inner spring and is wrapped in outside inner spring
Outer spring.
The improvement of technical solutions of the utility model is further used as, housing includes superposed U-shaped opening and positioned at U-shaped
Shell base below opening.
The improvement of technical solutions of the utility model is further used as, housing is PTFE materials.
The improvement of technical solutions of the utility model is further used as, the bottom of shell base is tilted provided with one with sealing ring inclined-plane
Angle identical shell bottom inclined-plane, sealing ring inclined-plane is oppositely arranged with shell bottom inclined-plane.
The improvement of technical solutions of the utility model is further used as, the bottom of shell base is horizontally disposed, positioned at shell base
Bottom be provided with two Sealing shield rings that are oppositely arranged, the sealing ring inclined-plane of two Sealing shield rings is oppositely arranged.
The beneficial effects of the utility model:This anti-high pressure combines general plug sealing ring by capsul and an at least Sealing shield ring
Combination is formed, and is caused in the sealing ring of combination formation, at least there is a contact of incline plane radially in each sub-assembly, so that
When combined seal ring is by extruding, it can be let out by the relative slip between Sealing shield ring or between Sealing shield ring and capsul
Pressure, and increase the relative width of combined seal ring, prevent each sub-assembly to be squeezed into equipment space, so as to more adapt to ultralow temperature work
Make environment, and reach more preferable service life.
