Envelope cone is set in end；Described envelope cone includes integrally formed stick harness, sealing round platform and work successively from front end to end
Dynamic post, stick harness small―gap suture, which is arranged on, to be sealed in cone seals set, and sealing round platform is arranged on outside cone seals set, seals the diameter of round platform
More than the internal diameter of envelope cone seals set, being fed through on envelope cone through hole, movable post for movable post activity is arranged spring taper, cone
The front end of spring and end difference top tight sealing round platform and stop collar；The location mid-shaft of the stick harness opens up the blind hole of one, blind
Hole opens up the multiple fluid through-holes of connection to the side wall of stick harness.
O-ring seal is provided between described housing and envelope cone seals set.
It is described cross oil hole ring-type be arranged at equal intervals stop collar it is cylindrical on, the number for crossing oil hole is 4.
Described fluid through-hole is symmetrical on stick harness to set 4.
The beneficial effects of the utility model：
1st, the utility model Simple oil extraction wellhead single flow device structure is novel, on production wellhead, when underground annex
After leaking, it can effectively prevent extraction crude oil recharge in pit shaft, it is to avoid the huge waste of the energy；
The 2nd, pressure gauge is set respectively on the both sides pipeline of the utility model Simple oil extraction wellhead single flow device, and single flow device is prevented
Under reflux working condition, the working condition in oil well can be intuitively judged according to the change of two gage pressures, and then quickly
Pinpoint the problems oil well, alleviate the workload of artificial investigation problem oil well, improve operating efficiency；
3rd, the utility model Simple oil extraction wellhead single flow device small volume, easy for installation, belongs to well head standard size accessory.

Embodiment
The utility model is further detailed below in conjunction with the accompanying drawings, referring to a kind of Simple exploitation shown in Fig. 1-Fig. 3
Oil well mouthful single flow device, is arranged on production wellhead pipeline, described single flow device include housing 1, stop collar 2, envelope cone 3,
Seal cone seals set 4 and envelope spring taper 5；The end of the housing 1 sets oil-out 6, and the front end nesting of housing 1 sets sleeve
Cone seals set 4, stop collar 2 is embedded in the inside stage casing of housing 1, and the middle position of stop collar 2 opens up envelope cone through hole 7, stop collar 2
Cylindrical position opens up multiple oil holes 8 excessively；The front end of the envelope cone seals set 4 sets oil inlet 9, envelope cone seals to cover 4
Envelope cone 3 is set in end；Described envelope cone 3 includes integrally formed stick harness 10, sealing round platform successively from front end to end
11 are arranged in envelope cone seals set 4 with movable post 12, the small―gap suture of stick harness 10, and sealing round platform 11 is arranged on cone seals and covered outside 4,
