It is close that activity is equipped in said structure, between the packing seal intracavitary outer tube internal shoulder left side, graphite packing Seal ring, loose gland outer wall, inner wall are equipped with circumferential groove, be equipped in circumferential groove respectively in housing pipe orifice, rotation The close-fitting y-shaped ring of pipe outer wall, the y-shaped ring opening is towards outer tube internal shoulder;The loose gland with The end face that outer tube internal shoulder left side combines is equipped with axial notch, and sealing ring is equipped in axial notch.
In said structure, it is equipped between the outer tube internal shoulder right side, the outer convex shoulder left side of rotating inner tube right end resistance to Bull ring.
In said structure, butterfly is set on the bolt between the bolt and nut component top nut and gland flange left side Spring component forms elastic self sealing structure.
In said structure, the face that is contacted on the gland with graphite packing is circular conical surface, the larger diameter end court of the circular conical surface To graphite packing.
Compared with prior art, the present invention it has the positive effect that:
1st, packing seal intracavitary is equipped with graphite packing so that the present invention has higher high temperature resistance.
2nd, high-temperature medium sealing ring is split ring, convenient for assembling;The outer wall of the outer convex shoulder of rotating inner tube right end set there are two with First annular slot is gone up, high-temperature medium sealing ring opening staggers in adjacent first annular slot, can in this way, significantly improving present invention sealing By property, the pressure-resistant performance of the present invention is improved.
3rd, loose gland, movable sealing are equipped between packing seal intracavitary outer tube internal shoulder left side, graphite packing Ring outer wall, inner wall are equipped with circumferential groove, are equipped in circumferential groove and are fitted close respectively with housing pipe orifice, rotating inner tube outer wall Y-shaped ring, y-shaped ring opening is towards outer tube internal shoulder, and when there is medium to rush at annular seal space, pressure medium makes Y shape Sealing ring opening is opened, and pressure medium is higher, and y-shaped ring opening Zhang get Yue is opened, i.e., pressure medium is higher, and sealing effect is got over It is good, therefore above-mentioned sealing structure significantly improves the high-voltage resistance capability of whirl compensator, also significantly improves sealing effect, significantly subtracts Few graphite packing leaks;The end face that loose gland is combined with outer tube internal shoulder left side is equipped with axial notch, axial Sealing ring is equipped in groove, further improves sealing reliability and high-voltage resistance capability.
4th, outer tube internal shoulder right side, rotating inner tube right end are equipped with wear ring between outer convex shoulder left side, avoid housing Pipe internal shoulder right side, the outer convex shoulder left side of rotating inner tube right end contact directly abrasion, significantly extend service life of the present invention.
The 5th, elastic self sealing structure is set, can the gap that generates of automatic compensation sealing filler abrasion, without manually adjusting, protect Hold reliable sealing state.
6th, the face contacted on gland with graphite packing is circular conical surface, the larger diameter end of the circular conical surface towards graphite packing, this Sample graphite packing in compaction process is axially and radially squeezed simultaneously so that outer wall of inner tube is tightly embraced in graphite packing, is carried High sealing reliability improves high-voltage resistance capability.
