Abstract
An automatic deviation regulation type wellhead packing box comprises a pressing cap, a pressing cover, a packing box body, a sealing packing, a deviation regulation box pressing cap, a deviation regulation box upper packing, a deviation regulation box and a deviation regulation box lower packing, and is characterized in that the packing box body is cylindrical, a deviation regulation seat is arranged at the lower end of the packing box body, a polish rod hole is formed in the center of the deviation regulation seat, and male threads are arranged on the upper portion; the sealing packing is arranged in the packing box body, the pressing cover is arranged above the sealing packing, the pressing cap connected with the packing box body through threads is arranged above the pressing cover, and the deviation regulation seat is arranged in the deviation regulation box; and the upper portion of the deviation regulation box is connected with the deviation regulation box pressing cap through threads, the lower portion of the deviation regulation box is connected with a wellhead tee joint, the deviation regulation box upper packing is arranged above the deviation regulation seat, and the deviation regulation box lower packing is arranged below the deviation regulation seat. According to the packing box, the deviation regulation seat can drive the packing box to integrally move along with thrust direction depending on thrust generated when a polish rod deviates towards arbitrary directions of the periphery, the polish rod does not deviate from the sealing packing in the packing box eccentrically, service life of the sealing packing is prolonged, and wellhead leakproofness and oil well production efficiency are improved.
Description
Technical field
The utility model relates to a kind of oilfield pumping well wellhead sealing device, specifically a kind of automatic deflection adjusting formula wellhead packing box.
Background technology
Oil pumping oil machine well wellhead packing box all is fixedly connected with well head at present, the function that does not possess tuningout, polished rod will the eccentric wear packing in oil pumper suspension point, polished rod and 3 decentraction of well head, the sealing of packing is reduced, cause the well head leakage of oil, pollute well head, waste crude oil, increase the workload of sanitation and hygiene and the workload of replacing packing, reduced the production time efficiency of oil well.
Summary of the invention
The purpose of this utility model is to provide a kind of automatic deflection adjusting formula wellhead packing box, overcomes the defective that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
