Sealing ring is as one indispensable critical piece of ultralow temperature equipment, to ultralow temperature equipment dependability, stability Guarantee play an important role.And ultralow temperature equipment sealedly designs Main Basiss API-6D-2008 and Britain both at home and abroad at present BS6364 standards are performed.Gas leakage, sealing effect are easily caused when all kinds of sealing rings are used under ultralow temperature equipment on the market Fruit is not good, although many producers are optimized to sealed structure and material performance, improved, and achieve some effects, but simultaneously Condition not up to needed for ultralow temperature equipment, therefore research and development Subzero valve seal, are the Scientific research equipments such as big science engineering Using and development important guarantee, with very important science and practical significance.
Existing sealing ring in ultralow temperature equipment by pressure when, easily squeeze into equipment space and cause sealing ring to damage It is bad.
Utility model content
The purpose of this utility model is that ultra-low temperature surroundings and non-damageable anti-high pressure can preferably be adapted to by providing one kind Combine general plug sealing ring.
Technical solution adopted in the utility model is:
A kind of anti-high pressure combines general plug sealing ring, including capsul and at least one sealing of the inside provided with turn are kept off Circle, Sealing shield ring is located at inner circumferential or the periphery of capsul, and the cross section of Sealing shield ring is provided with a relatively radially inclined sealing 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.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings:
