Description
Technical field
The utility model relates to oil field pumping well well head flexible protective corollary apparatus, particularly relates to a kind of bellows formula packing box.
Background technology
General oil well, well head adopts three kinds of packing boxs to seal it usually.One, adopt plain type packing box to seal, its advantage is processing, simple to operate, and shortcoming is that well mouth of oil well can be subjected to displacement phenomenon with the sucker rod position of oil pumper when geology motion change, that is: sucker rod partial wear phenomenon.When eccentric wear phenomenon occurs, because structure does not simply have elasticity, then can damage rubber packing and the packing box that frays, also may fray oil pumping polish rod in addition, causes stopping production.Two, adopt eccentric packing box to seal, its advantage can opposing very freely when generation eccentric wear phenomenon, thus protects polished rod and rubber packing.Shortcoming is processed complex, and during normal production, eccentric disc can wear and tear, and needs often to adjust.But, if adjustment is more loose, then can leakage of oil, adjustment tension, does not have again the effect freely adjusted.Therefore, if use for a long time, still rubber packing and polished rod can be damaged.Three, adopt the sealing of ball bearing type packing box, its advantage is that packing box can swing freely.Shortcoming is that structure, processed complex cost are high.When ball bearing gland is pressed tight, resistance is difficult to greatly activity freely, does not have sealing function during gland pine.When there is well head eccentric wear, being first worn near the rubber packing of ball bearing, until last rubber packing of packing box top is worn and leakage of oil, more threatening polished rod application life simultaneously.
Utility model content
The utility model provides a kind of bellows formula packing box, the technical problem of packing box inner part damage during to solve well head generation eccentric wear phenomenon.
For solving the problems of the technologies described above, the utility model provides a kind of bellows formula packing box, comprising:
Packing pressure cap;
Packing internal gland, is arranged at described packing pressure cap inner;
Rubber packing;
Packing box, is arranged at described packing pressure cap inner, and fastens with described packing internal gland;
Wherein, described rubber packing is arranged on packing box inside;
Packing ejects sleeve pipe, and described packing box fastens;
Polished rod, is arranged at described packing box inner;
Ball bearing supports, and ejects sleeve pipe be connected with described packing;
Elastic corrugated expansion loop, ejects sleeve pipe with described packing and is connected;
Support column, is connected with described ball bearing supporting;
Internal thread connects base, is connected with described elastic corrugated expansion loop;
Rubber gate external screw thread, is connected base and connects with described internal thread;
Wherein, described packing ejects sleeve pipe and is connected base with described internal thread and is connected with described elastic corrugated expansion loop, is formed overall with argon arc welding sealing.
By one or more technical scheme of the present utility model, the utility model has following beneficial effect or advantage:
The utility model provides a kind of bellows formula packing box, comprising: packing pressure cap; Packing internal gland; Rubber packing; Packing box; Packing ejects sleeve pipe; Polished rod; Ball bearing supports; Elastic corrugated expansion loop; Support column; Internal thread connects base; Rubber gate external screw thread.Concrete, packing is ejected sleeve pipe and is connected base with internal thread and is connected with elastic corrugated expansion loop, seal formation entirety with argon arc welding.In order to prevent elastic corrugated expansion loop axially-movable, to combine with support column with ball bearing supporting and making elastic corrugated expansion loop can only in horizontal freely-movable.When eccentric wear phenomenon occurs, the packing box on elastic corrugated expansion loop can horizontal freely-movable.And then avoid the eccentric wear of rubber packing, more effectively extend the application life of polished rod simultaneously.Utilize the in-built packing of packing box to eject sleeve pipe, the push-and-pull packing box of convenient makes the convenient loading of rubber packing, takes out.Thus when well head generation eccentric wear phenomenon, both protected polished rod, rubber seal, also make the convenient loading of rubber packing, take out.
Accompanying drawing explanation
The sectional drawing of a kind of bellows formula packing box that Fig. 1 provides for the utility model embodiment.
Detailed description of the invention
In order to make the utility model the technical staff in the technical field more clearly understand the utility model, below in conjunction with accompanying drawing, by specific embodiment, technical solutions of the utility model are described in detail.
See Fig. 1, it is the sectional drawing of a kind of bellows formula packing box that the utility model embodiment provides.
In FIG, bellows formula packing box comprises:
Packing pressure cap 1; Packing internal gland 2; Rubber packing 3; Packing box 4; Packing ejects sleeve pipe 5; Polished rod 6; Ball bearing supporting 7; Elastic corrugated expansion loop 8; Support column 9; Internal thread connects base 10; Rubber gate external screw thread 11.
Introduce the annexation of all parts below.
Packing internal gland 2, is arranged at described packing pressure cap 1 inner;
Rubber packing 3, is arranged on described packing box 4 inner;
Packing box 4, is arranged at described packing pressure cap 1 inner, and fastens with described packing internal gland 2;
Packing ejects sleeve pipe 5, and described packing box 4 fastens; In addition, described packing ejects sleeve pipe 5 and the described packing internal gland 2 described rubber packing 3 of engaging jointly, makes described rubber packing 3 closely be arranged at described packing box 4 inner.
Polished rod 6, is arranged at described packing box 4 inner; In actual applications, polished rod 6 is stocks, arranges bellows formula packing box inner, and runs through whole bellows formula packing box.
Ball bearing supporting 7, elastic corrugated expansion loop 8 eject sleeve pipe 5 with described packing respectively and are connected;
Support column 9, is connected with described ball bearing supporting 7;
It is inner that elastic corrugated expansion loop 8 is arranged at described support column 9;
