Abstract
The utility model relates to a wellhead polished rod sealer which is characterized by mainly comprising a sealing packing device, a rod breaking blowout prevention protector and a bias correcting interface, wherein the rod breaking blowout prevention protector mainly comprises a sealer main body, a support pole seat and a rod breaking blowout prevention device; the sealer main body forms a cross-shaped whole body by two sections of circular pipes which are vertical mutually; an inner hole at the upper end part of the circular pipe positioned at the vertical part is internally provided with the rod breaking blowout prevention device; the rod breaking blowout prevention device mainly comprises a steel ball frame, a steel ball, a spring and a pressure spring cover; a central hole of the steel ball frame is internally provided with a reset main spring; the reset main spring is press-connected with the pressure spring cover which is in thread connection with the sealer main body; and a blind hole is vertically arranged at the central hole of the steel ball and is internally provided with a steel ball spring and the steel ball. The wellhead polished rod sealer has the benefits that the rod breaking blowout prevention protector adopts a sealing mode of the steel ball and a valve seat, resists high pressure, and is reliable in sealing. When an energy-stored spring and the steel ball generate rod breaking, the steel ball can be conveyed to a polished rod fast so as to block the rest space and prevent well fluid from spurting out.
