Description
Technical field
The utility model relates to a kind of packing box environmental control system, is specifically related to a kind of well mouth of oil well packing box environmental control system.
Background technology
Well mouth of oil well packing box ensures that a kind of device realizing wellhead sealing normally produced by oil well.Along with oil field is continually developed, well water raises year by year, and the corrosivity of formation water is also increasing.The leakage of bare rod corrosion, packing thorn happens occasionally, and can cause light rod-broken time serious, cause pollution in wide area, and increase the workload of oil recovery workman field control, rate when impact drives a well, directly has influence on oil well output.
Utility model content
The utility model is intended to solve the problem, and provide a kind of well mouth of oil well packing box environmental control system, the utility model is easy to connect, has packing box lubrication, seepage oil recovery and the effect of falling polished rod in well anti-pricked.This practical new technical scheme is as follows:
A kind of well mouth of oil well packing box environmental control system, comprise packing gland, one-level packing, one-level packing housing, anti-polluting tube, valve ball, spring, plug, butter hole, secondary packing, sump oil case, oil leak hole, retaining thread hole, described packing gland is threaded with one-level packing housing, described one-level packing is placed in one-level packing housing upper inner chamber, the sidewall of described one-level packing housing is provided with anti-polluting tube and butter hole, valve ball and spring is provided with in described anti-polluting tube, described plug is threaded with anti-polluting tube, plug Compress Spring, spring promotes again valve ball with polish rod rolling, described one-level packing lower housing portion is threaded with sump oil case, the top inner chamber of described sump oil case places secondary packing, sump oil case is simultaneously as secondary packing chamber, described sump oil case sidewall bottom is provided with oil leak hole, described sump oil case diapire is provided with retaining thread hole, described retaining thread hole is used for the utility model to be fixed on above former packing box.
On the basis of technique scheme, the relative position on the sidewall of one-level packing housing is located in described anti-polluting tube and butter hole.
On the basis of technique scheme, described sump oil case sidewall bottom is provided with two oil leak hole.
On the basis of technique scheme, two oil leak hole on described sump oil case sidewall are positioned at the opposite side of bottom.
On the basis of technique scheme, described oil leak hole is provided with internal thread, and oil leak hole is threaded connection outside oil guide pipe, is entered by sump oil in other containers.
On the basis of technique scheme, described sump oil case diapire is provided with four retaining thread holes.
When well mouth of oil well thorn leaks, sump oil enters sump oil case from lower to upper, enters in other containers through oil leak hole, plays antipollution effect.After polished rod takes off because corrosion or load heavily break, spring can eject valve ball, and valve ball drops on longitudinal position of polished rod, thus plays the effect of blowout prevention.
The utility model tool has the following advantages:
1, after packing oil leakage, oil directly imports in other containers, and well head is pollution-free.
2, butter enters cavity Castor Oil polished rod by butter hole, plays antisepsis.
3, manufacture, easy for installation, and cost is low.
