Feed liquor runner, the second annular reservoir 412 can be in communication with the outside by liquid-passing hole 511 and feed liquor runner.Specifically, liquid storage
Feed liquor runner is offered in sealing shroud 1 and goes out liquid stream road, and one is feed liquor runner, and one is liquid stream road, is replacing sealing fluid
When body, sealing liquid is inwardly filled with from feed liquor runner, then collect from go out liquid stream road flow out liquid, when go out liquid stream road outflow
When liquid is pollution-free, liquid stream road is closed out, then liquid storage sealing shroud 1 is full of by feed liquor runner.
Wherein, 1 outer wall of liquid storage sealing shroud is provided with the first removable seal blocking piece 711, the first removable seal blocking piece 711
For blocking feed liquor runner, can be connected through a screw thread between the first removable seal blocking piece 711 and feed liquor runner.
1 outer wall of liquid storage sealing shroud is provided with the second removable seal blocking piece 712, and the second removable seal blocking piece 712 is used for
It blocks out liquid stream road, the second removable seal blocking piece 712 and goes out between liquid stream road and can be connected through a screw thread.
It is equipped in the alternative of the present embodiment, between annular scraper 8 and first annular reservoir 411 and is surrounded on internal layer brill
Seal assembly outside bar 2.
Seal assembly includes packing seal element 911, sealing ring 912；Wherein annular scraper 8 takes the lead in stopping mud, and ring
Shape scraper plate 8 has certain hardness, ensures that annular scraper 8 is fitted closely with 2 outer wall of internal layer drilling rod, and annular scraper 8 is to interior
Layer drilling rod 2 also has certain lubricant effect, reduces the damage that its outer wall is subject in sliding of internal layer drilling rod 2.And filler is close
Sealing 911 has certain corrosion resistance, slows down the rate that packing seal element 911 goes bad under the action of mud, outer to improve
Sealing effect between layer drilling rod 3 and internal layer drilling rod 2.
After the sealing device installation of drilling rod connection, sealing ring 912 is in compressive state, can release stress outward,
Specifically, sealing ring 912 is in the state that fits closely with packing seal element 911, therefore sealing ring 912 can be to packing seal element
911 release stress, and so that 911 moment of packing seal element is in impaction state, preferably realize sealing effect.
Because packing seal element 911 during sealing operation, will produce centainly by the pressure and pulling force of internal layer drilling rod 2
Deformation, so that 911 some regions of packing seal element is in relaxed state, the application passes through sealing ring 912 and packing seal element
911 connections, it is ensured that packing seal element 911 keeps impaction state, makes close between packing seal element 911 and internal layer drilling rod 2
Effect moment holding optimum state is sealed, to improve the sealing effect between outer layer drilling rod 3 and internal layer drilling rod 2.
Along run of steel direction, sealing ring 912, packing seal element 911 and annular scraper 8 are set gradually, and sealing ring
912, packing seal element 911 is respectively positioned between annular scraper 8 and first annular reservoir 411；Sealing ring 912 and packing seal element
911 fit closely.
Hard baffle ring 913 is provided between sealing ring 912 and packing seal element 911.
Specifically, annular scraper 8 withstands packing seal element 911 upwards, sealing ring 912 downwardly against packing seal element 911,
So that packing seal element 911 is in compacting tightening state, improves the sealing effect of packing seal element 911.
When sealing ring 912 is directly contacted with packing seal element 911, because sealing ring 912 has elasticity, 912 meeting of sealing ring
From on packing seal element 911 certain point or a certain region to packing seal element 911 provide pressure, rather than comprehensively uniformly to
Packing seal element 911 provides pressure, simultaneously as packing seal element 911 is not homogeneous hard material, so in this way
911 unbalance stress of packing seal element can be caused, so that some regions of packing seal element 911 is in compaction state, some regions are still
So relaxation, to influence sealing effect.Therefore hard baffle ring 913 is set between sealing ring 912 and packing seal element 911, it is close
Seal 912 is released stress to hard baffle ring 913, and hard baffle ring 913 is whole to be moved down, to which sealing ring 912 can be to filler
Sealing element 911 provides uniform pressure, makes packing seal element 911 generally in compacting tightening state, improves packing seal element
911 sealing effect.
Wherein, between more than 8 person of ring skeleton 5- sealing rings 912- hard baffle ring 913- packing seal element 911- annular scrapers
It sets gradually, and upper-lower compacting coordinates.
