Description
Technical field
The utility model relates to oil field equipment, particularly relates to a kind of self-pressure adjustable offset oil well head blowout prevention box.
Background technology
Rod-pumped well in process of production, due to the impact of multiple external factor, there will be the deflection of polished rod and well head usually; and then cause between polished rod and well head packing eccentric wear occurs; cause well head packing to wear and tear comparatively large, application life is short, and the replacement cycle is short, the input that adds cost of production.Also there will be the problem of well head leakage of oil simultaneously; thus certain pollution is caused to surrounding enviroment; the general set screw adjusting oil pumper axis by school machine adjusts at present; but it is very inconvenient to operate; comparatively easy way installs deviation correcting device at well head, but existing deflection-regulating device of well head complex structure, price is relatively high; and there is no blowout prevention function, there is the more with Non-follow control of blowout hookup.
Utility model content
The utility model is intended to the deficiency for existing in background technology, and proposes self-pressure adjustable offset oil well head blowout prevention box.
Self-pressure adjustable offset oil well head blowout prevention box of the present utility model, by sealed body, tuningout hand lever, spray-proof ball and packing gland are formed, its gland for packing box is connected with packing box cutting ferrule and is connected and fixed with sealed body screw socket suitable for reading, lower cover is connected with tube connector cutting ferrule and is connected and fixed with sealed body end opening screw socket, described packing box is built-in with packing, top is sealed by packing gland screw socket, the both sides of sealed body top radial direction are respectively equipped with the tuningout seat with its inner space, tuningout hand lever is equipped with in tuningout seat, the inner of tuningout hand lever is all fixed with the nylon ring in sealed body inner chamber, the outer end of described tuningout seat is equipped with tuningout gland, sealed body lower outside is provided with the blowout-preventing ball seat communicated with its inner chamber, blowout-preventing ball seat is built-in with spray-proof ball, the outer end of blowout-preventing ball seat is provided with ball seat gland, low elasticity spring is provided with between described spray-proof ball and ball seat gland, spray-proof ball is connected with one end of pull bar, the other end of pull bar is placed in the outer end of blowout-preventing ball seat through ball seat gland.
As further improvement of the utility model, in described tuningout seat, the front end of tuningout hand lever is equipped with sealing ring.
As further improvement of the utility model, in described packing box, the top of packing is provided with nylon packing.
As further improvement of the utility model, the periphery of described spray-proof ball is provided with abrasionproof gum cover.
Self-pressure adjustable offset oil well head blowout prevention box of the present utility model, structure is simple, cost is low, have the dual-use function of blowout prevention box tuningout, difficult problem is solved when enormously simplify polished rod and packing generation eccentric wear, effectively reduce packing wearing and tearing, contribute to the application life extending packing, reduce cost of production, blowout hookup self-pressure starts, and rapidly fast, can realize blowout prevention function the very first time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 to self-pressure adjustable offset oil well head blowout prevention box of the present utility model, be described further.
Self-pressure adjustable offset oil well head blowout prevention box of the present utility model, be made up of sealed body 1, tuningout hand lever 2, spray-proof ball 3 and packing gland 4, its gland for packing box 5 be connected with packing box 6 cutting ferrule and be connected and fixed with sealed body 1 screw socket suitable for reading, lower cover 7 is connected with tube connector 8 cutting ferrule and is connected and fixed with sealed body 1 end opening screw socket.Described packing box 6 is built-in with packing 9, top is sealed by packing gland 4 screw socket, the both sides of sealed body 1 top radial direction are respectively equipped with the tuningout seat 10 with its inner space, tuningout hand lever 2 is equipped with in tuningout seat 10, the inner of tuningout hand lever 2 is all fixed with the nylon ring 11 in sealed body 1 inner chamber, carries out tuningout by regulating tuningout hand lever 2 pairs of polished rods 20.The outer end of described tuningout seat 10 is equipped with tuningout gland 12, and tuningout hand lever 2 is through tuningout gland 12.Sealed body 1 lower outside is provided with the blowout-preventing ball seat 13 communicated with its inner chamber, blowout-preventing ball seat 13 is built-in with spray-proof ball 3, the outer end of blowout-preventing ball seat 13 is provided with ball seat gland 14, the outer end that spray-proof ball 3 is connected with one end of pull bar 16, the other end of pull bar 16 is placed in blowout-preventing ball seat 13 through ball seat gland 14, the pull bar 16 in ball seat gland 14 is provided with low elasticity spring 15.In tuningout seat 10, the front end of tuningout hand lever 2 is equipped with sealing ring 17.In packing box 6, the top of packing 9 is provided with nylon packing 18, and the periphery of spray-proof ball 3 is provided with abrasionproof gum cover 19, farthest reduces the friction of spray-proof ball and polished rod 20.
After polished rod 20 comes off, spray-proof ball 3, by the thrust of low elasticity spring 15, is pushed in the inner chamber of sealed body 1, thus realizes blowout prevention function by spray-proof ball, during from new installation polished rod 20, manually pulls pull bar 16 to be returned to by spray-proof ball in blowout-preventing ball seat 13.
