In said structure, described rotating inner tube annular outer platform outer surface is provided with annular groove II, is provided with sealing ring in annular groove II II, sealing ring II closely cooperates with outer sleeve inner surface, constitutes radial seal structure II.
In said structure, the bolt assembly stretching out sealed pressing sleeve flange right side is provided with butterfly spring assembly, presses with sealing The elastic self sealing structure of set composition together.
In said structure, described airtight and watertight padding is several v-rings axially arranged, described v-ring opening Towards trocar sheath internal shoulder.
This utility model compared with prior art, has the positive effect that:
1. it is provided with radial seal structure I between trocar sheath internal shoulder inner surface and rotating inner tube outer surface, defines the 3rd Road seals, and stops medium to enter sealed pressing sleeve left side, outer sleeve inner surface, rotating inner tube outer surface, trocar sheath annular convex In annular seal space between platform right side, significantly improve voltage endurance capability of the present utility model.
2. it is provided with radial seal structure II between rotating inner tube annular outer platform outer surface and outer sleeve inner surface, defines 4th road seals, and stops medium to enter rotating inner tube outer surface, outer sleeve inner surface, trocar sheath annular inner convex platform left side, rotation Turn in the annular seal space between inner tube annular outer platform right side, improve voltage endurance capability of the present utility model further.
3. on the bolt assembly stretching out sealed pressing sleeve flange right side, it is provided with butterfly spring assembly, forms together with sealed pressing sleeve Elastic self sealing structure, can make airtight and watertight padding keep coordinating shape closely with rotating inner tube outer surface, outer sleeve inner surface all the time State, reaches the most elastic self sealss state, high pressure resistant, seals persistently, reliably.
4. airtight and watertight padding is v-rings of several axial arrangements, v-ring opening towards trocar sheath internal shoulder, So, can radially expand during pressurized set axial compression, while forming axial seal, produce preferable radial seal, further Improve this utility model high temperature high voltage resistant performance;V-ring opening is towards trocar sheath internal shoulder, close when there being pumped (conveying) medium to enter In envelope annular seal space between gland left side, outer sleeve inner surface, rotating inner tube outer surface, trocar sheath annular inner convex platform right side Time, under pumped (conveying) medium pressure effect, v-ring opening opens, in v-ring and rotating inner tube outer surface, trocar sheath Surface fits more closely against, and further improves this utility model high voltage performance.
