This application discloses a multifunctional blowout preventer sealer for the wellhead of a pumping unit, which includes an upper gland, a packing box main body, and a lower gland. The universal ball mechanism is located between the packing and the lower gland. The first universal ball mechanism includes a first hemisphere and a first ball seat with a hemispherical groove. The first hemisphere and the first ball seat are provided with a light supply rod. Through the first through hole, the plane part of the first hemisphere is in contact with the packing, the spherical part of the first hemisphere is located in the hemispherical groove, and the end of the first ball seat away from the hemispherical groove is in contact with the lower gland When the first hemisphere receives the eccentric force of the polished rod and rotates in the hemispherical groove, the packing rotates with the first hemisphere so that the axes of the first hemisphere, the packing and the polished rod are on the same straight line. Such setting solves the problem that the existing blowout preventer sealer needs to be corrected forcibly, the deviation correcting effect is poor, time-consuming and laborious, the wear degree of the polished rod and the filler is easily aggravated, and the service life of the polished rod is shortened.
Description
technical field [0001] The present application relates to the technical field of oil pumping units, and more specifically, relates to a multifunctional blowout prevention sealer for the wellhead of the pumping unit. Background technique [0002] Pumping unit is a kind of machinery and equipment for oil extraction, commonly known as "kowtow machine". The pumping unit is the most important lifting equipment in the rod pumping system. The problem of eccentric wear between the polished rod of the pumping unit and the sealer is common in the production process. During the up and down operation of the polished rod of the pumping unit, the one-sided wear of the sealing packing in the sealer will accelerate and affect production. Generally, the correction device is forced to correct the deviation. In the case of eccentricity of the polished rod, it is necessary to use a pipe wrench to correct it. The service life of the oil well increases the frequency of replacing the polished ro...
