Abstract

The invention belongs to an oil well sucker rod sealing device, in particular to a blowout-prevention deviation-adjusting multi-sealing sucker rod sealer. The blowout-prevention deviation-adjusting multi-sealing sucker rod sealer comprises a blowout-prevention device, an auxiliary sealing device, a main sealing cover, a deviation-prevention biconical sealing rubber block, a main sealing base, a secondary sealing device and a deviation-adjusting device; and the sealer is characterized in that the blowout-prevention device is arranged on the auxiliary sealing device; the main sealing cover is arranged at the lower end of the auxiliary sealing device; the deviation-prevention biconical sealing rubber block is arranged in the main sealing base; the main sealing cover is in screwed connection with the main sealing base; the secondary sealing device is arranged at the lower end of the main sealing base; and the secondary sealing device is arranged on the deviation-adjusting device. The sealer has the advantages of excellent multi-sealing effect, simple structure, and buckled concave and convex surfaces of two sealing flaps; and the sealer is difficult to deviate, convenient to replace, reduces the labor intensity, prevents blowout and is free of pollution.

Description

The multi-stage sealed pumping rod sealer of blowout prevention tuningout
Technical field
The invention belongs to the well rod sealing device, the multi-stage sealed pumping rod sealer of particularly a kind of blowout prevention tuningout.
