Further, the outer cylinder seat extends to the inner side of the sealing bin, so that the hard sealing seat can be screwed and pressed.
Furthermore, the sucker rod passes through between two soft seal seats, gives soft seal seat pressure through outer barrel casing seat, and soft seal seat can accomplish and lock the sucker rod.
Compared with the prior art, the utility model discloses an aligning deviation-adjusting polished rod sealer improves through its shut-in valve of aligning deviation-adjusting polished rod sealer to can carry out the secondary shut-in when the sucker rod drops off, avoid appearing the oily earth's surface condition of pollution of bleeding.
