Abstract

The utility model belongs to well sucker rod sealing devices, in particular to a blowout-preventing offset-regulating multistage-sealing sucker rod sealer which comprises a blowout preventer, an auxiliary sealing device, a main seal cover, an offset-preventing biconical seal rubber block, a main seal base, a secondary sealing device and an offset regulating device. The blowout-preventing offset-regulating multistage-sealing sucker rod sealer is characterized in that the blowout preventer is mounted on the auxiliary sealing device, the main seal cover is disposed at the lower end of the auxiliary sealing device, the offset-preventing biconical seal rubber block is disposed in the main seal base, the main seal cover is connected with the main seal base in a threaded manner, and the secondary sealing device is disposed at the lower end of the main seal base and is disposed on the offset regulating device. The blowout-preventing offset-regulating multistage-sealing sucker rod sealer has the advantages that multistage sealing is effective, the structure is simple, uneven sides of two seal flaps are butt-fastened, offset fastening occurs rarely, replacement is convenient, labor intensity is reduced, blowout is prevented, and pollution is avoided.

Description

The multi-stage sealed pumping rod sealer of blowout prevention tuningout
Technical field
The utility model belongs to the well rod sealing device, particularly the multi-stage sealed pumping rod sealer of a kind of blowout prevention tuningout.
Background technology
At present, existing sucker rod sealing device, loading and unloading are inconvenient, change packing and need stop well, and labour intensity is big, and sealing effectiveness is bad.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of blowout prevention tuningout multi-stage sealed pumping rod sealer, anti-inclined to one side biconial sealed gluing block in the multi-stage sealed pumping rod sealer of this blowout prevention tuningout is to be made of left side sealing lobe and right sealing lobe, and the male and fomale(M﹠F) of two sealing lobes is up and down biconial to being buckled together, middle is circular, be contained on the primary seal base, oil pumper can normally move during replacing, need not stop well, it is convenient to change, good sealing effect.
The technical scheme in the invention for solving the technical problem is: the multi-stage sealed pumping rod sealer of a kind of blowout prevention tuningout, by blowout hookup, auxiliary sealing device, the primary seal lid, anti-inclined to one side biconial sealed gluing block, the primary seal base, two stage sealing device and deviation correcting device are formed, its special character is: blowout hookup is installed on the auxiliary sealing device, the auxiliary sealing device lower end is provided with the primary seal lid, anti-inclined to one side biconial sealed gluing block is contained in the primary seal base, primary seal lid and the screwed connection of primary seal base, primary seal base lower end is provided with two stage sealing device, and two stage sealing device is contained on the deviation correcting device.
The beneficial effects of the utility model are: multi-stage sealed effective, simple in structure, the male and fomale(M﹠F) make-up of two sealing lobes is difficult for button partially, and it is convenient to change, and reduces labour intensity, and blowout prevention is pollution-free.
