Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of packing box 100, is applied on the oil pumper of oil well.Packing box 100 comprises: large gland 10; Contain the stuffing box 20 of packing, its top 21 wears and is connected in large gland 10; Antitheft stuffing box 30, it can axially movably be set in the bottom 23 of stuffing box 20, between the bottom 23 of stuffing box 20 and the diapire 31 of antitheft stuffing box 30, is filled with oil-leakage-prevention filler.
Specifically, large gland 10 entirety are cylindrical tube shape, and its inside wall 17 is provided with thread segment.Large gland 10 has relative upper end 11 and lower end 13, and its upper end 11 extends radially inwardly and is formed with annular gland extension 15, and the internal ring wall of this gland extension 15 is provided with thread segment.
The upper end 11 of large gland 10 is provided with clamp nut 40.The upper end of clamp nut 40 is threaded on the thread segment of gland extension 15, and its lower end is housed in large gland 10 and is threaded with the inside wall 17 of large gland 10.By rotatably compressing nut 40, clamp nut 40 is axially moved down, thereby can exert pressure to the packing in stuffing box 20.
Stuffing box 20 is cylindrical tube shape substantially, its top 21 lateral walls are threaded mutually with the inside wall 17 of large gland 10, its 21 inner sides, top are equipped with little gland 50, the top 21 inside wall phase interference fits of little gland 50 and stuffing box 20, the lower end of the top of little gland 50 and clamp nut 40 connects, by rotatably compressing nut 40, clamp nut 40 is axially exerted pressure to little gland 50 downwards, makes little gland 50 compress the packing in stuffing box 20.The bottom 23 of stuffing box 20 radially inwardly convexes with extension 27, and the packing being arranged in stuffing box 20 is pressed between little gland 50 and extension 27.Further, the bottom 23 of this stuffing box 20 radially outward convexes with 25, the first stopper sections 25, the first stopper section and is positioned on same level line with extension 27.
Antitheft stuffing box 30 is cylinder barrel shaped substantially, and it can axially movably be set in the bottom 23 of stuffing box 20.The top 33 of antitheft stuffing box 30 radially inwardly convexes with the second stopper section 35, and these the second stopper section 35 contacts are in the lower end 13 of large gland 10.In the utility model, the outside of stuffing box 20 is arranged with flexible member 60, this flexible member 60 can be spring, flexible member 60 is folded between the bottom 23 of stuffing box 20 and the top 33 of antitheft stuffing box 30, specifically, this flexible member 60 is folded between the first stopper section 25 and the second stopper section 35, thereby makes antitheft stuffing box 30 under the resilient force of flexible member 60, can axially movably be set in the bottom 23 of stuffing box 20.
Oil-leakage-prevention filler is installed with in antitheft stuffing box 30, and it is between the diapire 31 of antitheft stuffing box 30 and the extension of stuffing box 20 27, the first stopper section 25.In the present embodiment, oil-leakage-prevention filler is oil immersion asbestos cord.
In the time that large gland 10 is not opened, do not exert pressure to oil-leakage-prevention filler in the extension 27 of stuffing box 20 and the first stopper section 25, and now, oil-leakage-prevention filler is in fluffy state; In the time opening large gland 10, because the top 33 of antitheft stuffing box 30 is no longer subject to the contact of large gland 10, now, second stopper section 35 on antitheft stuffing box 30 tops 33 by under the resilient force at flexible member 60 by axial jack-up upwards, the extension 27 that is positioned at stuffing box 20 bottoms of antitheft stuffing box 30 axially moves down to push oil-leakage-prevention filler with the first stopper section 25 by relative antitheft stuffing box 30, oil-leakage-prevention filler compressed and be sealed on polished rod, effectively preventing leakage of oil.
According to an embodiment of the present utility model, in order to make to there is better sealing effectiveness between stuffing box 20 and antitheft stuffing box 30, between the second stopper section 35 and the sidewall of stuffing box 20, be provided with sealing ring 70, in the time that stuffing box 20 and antitheft stuffing box 30 relative position occurs move, sealing circle 70 can effectively prevent that the situation of crude oil leakage from occurring.
This packing box 100 in use, is arranged on the oil pumper of oil well, and the polished rod of oil pumper is along axially through packing box 100, and antitheft stuffing box 30 is welded on that on oil pumper, to realize packing box 100 entirety fixing.Under the pressure of clamp nut 40, little gland 50 is towards the interior mobile packing that compresses of stuffing box 20, realizes on the polished rod that packing is fitted in oil pumper closely, prevents that crude oil from leaking along polished rod.In the time that large gland 10 is destroyed or be disassembled, clamp nut 40 is no longer exerted pressure to little gland 50, the seal failure of packing to oil-extractor polish-rod, the flexible member 60 being now folded between antitheft stuffing box 30 and stuffing box 20 axially moves down antitheft contact stuffing box 30, so that the relatively antitheft stuffing box 30 of stuffing box 20 axially moves down, thereby make the extension 27 of stuffing box 20 bottoms, the first stopper section 25 compresses the oil-leakage-prevention filler that is positioned at antitheft stuffing box 30 downwards, make oil-leakage-prevention filler tightr, realize the sealing to polished rod, prevent crude oil leakage.
Packing box 100 of the present utility model, in the time that large gland 10 is destroyed or dismantle, realize by axially relatively moving of stuffing box 20 and antitheft stuffing box 30 object that compresses the oil-leakage-prevention filler that is positioned at antitheft stuffing box 30, so that oil-leakage-prevention filler tight seal is on the polished rod of oil pumper, effectively realize the object that prevents that crude oil oil from leaking, and then prevent that crude oil from being stolen.
These are only several embodiment of the present utility model, those skilled in the art can carry out various changes or modification and not depart from spirit and scope of the present utility model the utility model embodiment according to the disclosed content of application documents.
