Embodiment
Embodiment 1
As Figure 1-4, a kind of producing well smooth rod break anti-blowout apparatus, described device include one in it and are provided with envelope
The housing of stifled chamber 5, be arranged on housing and respectively positioned at the upside of closure chamber 5 and downside and can be with oil-extractor polish-rod 3
The upper through hole and lower through-hole being slidably matched, the ball sealer 8 for having a diameter larger than through-hole diameter being arranged in closure chamber 5, if
Be placed in ball sealer 8 and block chamber wall 18 between back-moving spring 10, device it is non-closure working condition when ball sealer 8 sphere with
Oil-extractor polish-rod 3 is in rolling contact, and when oil-extractor polish-rod 3 breaks de- closure working condition, ball sealer 8 is in back-moving spring 10 and oil
Ball face sealing is formed with upper through hole in the presence of well pressure, realizes the closure to oil gas leakage；Closure is provided with closure chamber 5
The position limiting structure of ball 8, the position limiting structure are arc-shaped baffle；Small plug wire 9 is provided with the closure chamber wall 18, blocks chamber
Pad 17 is provided between locular wall 18 and small plug wire 9 and seals original paper；The lower ending opening of upper through hole on described big plug wire 16 is
The frustum cone structure of one expansion segment；The upside of closure chamber 5 is combined with one big plug wire 16, big plug wire 16 and stifled chamber by screw thread
Room 5 is provided with pad 17 between upside, and a upper through hole being slidably matched with oil-extractor polish-rod 3 is offered on big plug wire 16,
Ball sealer 8 is hollow ball-shape body, and the inner ring diameter of spring 10 is less than the diameter of ball sealer 8.
When in use, when oil well normally produces, during oil pumper normal operation, oil well sealing is to lean on sealed packing box 4
Complete, because, when oil-extractor polish-rod 3 moves up and down in well bucket, the sealing original paper in the sealed packing box 4 of well head
Tight sealing surface can be formed with the wall of oil-extractor polish-rod 3 so that the oil gas in well bucket can not spray, when sealed packing box 4 is run
When normal, the closure chamber 5 below sealed packing box 4 would be at off position, as shown in figure 1, at this moment, closure
Ball sealer 8 in chamber 5 will contact with the wall of oil-extractor polish-rod 3, because ball sealer 8 is spheroid, when oil-extractor polish-rod is transported about 3
When dynamic, ball sealer 8 can rotate automatically, so on the one hand reduce the resistance to oil-extractor polish-rod 3, while can also prevent from blocking
Ball 8 reduces the mutual abrasion between oil-extractor polish-rod 3, extends the service life of oil-extractor polish-rod 3, at the same can also prevent because
The long term wear modification of ball sealer 8 and have influence on the sealing property of ball sealer 8.
A kind of usually used cylinder produced by special material of the exactly current petroleum industry of oil-extractor polish-rod 3 is in fact
Heart polished rod, its top are connected by cubic clamp 2 with oil pumper lifting rope 1, below be connected with the sucker rod in the well bucket
Connect, the effect of oil-extractor polish-rod 3 is exactly pulling force caused by oil pumper, by lifting rope 1, is delivered on the sucker rod in well bucket
Lower motion, pumps the crude oil of stratum depths, so as to complete pumping operation.
The hollow-core construction of ball sealer 8 can floating upward quickly, when ball sealer 8 is in oil pipeline 12, oil gas after light rod-broken
In the presence of the direction of motion 13 in pipeline, when ball sealer 8 is shifted onto the closure seat that closure chamber 5 exports, ball sealer 5 is complete
Contacted with upper bed-plate, reach fully sealed position, so as to block oil gas outwards to overflow, to reach the purpose of rapid closure well head.
The spring 10 is disconnected de- when oil-extractor polish-rod 3, after slipping into well bucket, ball sealer quickly can be pushed into closure chamber
Room lower inlet seat, promptly and accurately ball sealer 8 is pushed to block the lower inlet seat of chamber 5.
The big plug wire 16, above closure chamber 5, when oil-extractor polish-rod 3 is disconnected de-, ball sealer 8 is in well bucket pressure
And when being moved upwards under return pipe pressure, ball sealer 8 can be bottled up and go out closure chamber, so as to reach closure well head, prevented outside oil gas
Let out.
The pad 17, to seal original paper, ensure the sealing property between each component, high pressure resistant, oil resistant gas corrosion.
The small plug wire 9 is arranged on closure chamber wall 18, and after oil-extractor polish-rod 3 is disconnected to come off into well bucket, ball sealer 8 is complete
After the closure of paired well head, prevent that OIH gas from, from the important function of closure chamber 5 side ejection, being for side on the other hand
Just installation closure chamber 5, after closure chamber 5 is arranged on well head, small plug wire 9 is opened, successively installation ball sealer 8, pad 17,
Spring 10, small plug wire 9 is then loaded onto, be so more beneficial for blocking the installation of chamber, meanwhile, there is this design, be also beneficial to
Regular maintenance and maintenance to blocking chamber 5.
