Technical field
The utility model belongs to oil exploitation fixture technology field, and in particular to a kind of preventer of eccentric abrasion prevention formula.
Background technology
In oil exploitation utensil, polished rod is to realize the connection between sucker rod and polished rod eye and special " oil pumping
Bar ".Because the topmost in sucker rod, stress is maximum, so the diameter of polished rod is bigger than oil pumping shank diameter, the rank of steel will
Height, surface are more smooth.Main function is：1st, combined with the packing in packing box, sealing wellhead, prevent oil, gas and water leakage.2、
Realize the link transition between sucker rod and polished rod eye.3rd, indicator diagram measurement is completed.4th, the various operations of well head are realized.Such as touch pump,
Adjust pump extension etc..
At present, when oil mining operation operates, due to the effect of lifting system, polished rod moves in extracting device of oil；Adopt
When oily, if the position that polished rod skew extracting device of oil is original, easy to wear when polished rod is up and down reciprocatingly run, polished rod and blowout prevention are caused
Device is scrapped；In addition, having certain gap between blowout prevention box and polished rod, easily there is oil leak thing in the reciprocal running of polished rod
Therefore increase oil recovery work labor intensity and problem of environmental pollution.
Utility model content
The purpose of this utility model is to provide a kind of preventer of eccentric abrasion prevention formula, solves the easy eccentric wear of polished rod in oil producing operation
The problem of.
The utility model is the technical scheme adopted is that a kind of preventer of eccentric abrasion prevention formula, including pillar buoy, outside pillar buoy
Sealing drum is socketed with, two parallel anti-deflection devices are offered on the barrel of pillar buoy, each anti-deflection device is prevented including at least three
Inclined hole, anti-bias hole are evenly distributed on pillar buoy circumference, there is adjustment spring in anti-bias hole, adjustment spring one end connection sealing drum
Inwall, adjusts another end in contact connection ball of spring, and ball is exposed to the inwall of pillar buoy, pillar buoy both ends inwall connection oil
Water-stop device.
The characteristics of the utility model, also resides in：
Anti-bias hole is not more than the diameter of ball in the aperture of pillar buoy inwall.
Some seal grooves are offered on the outer tube wall of pillar buoy.
Seal groove at least 3, and positioned at the both sides in every group of anti-bias hole.
Seal groove interior sealing connects sealing ring, and sealing ring connects the inwall of sealing drum.
The both ends of sealing drum offer taper button.
The beneficial effects of the utility model are：
Eccentric abrasion prevention formula blowout preventer of the present utility model replaces sliding friction by rolling friction, in the thrust of spring
Under righting by force, polished rod is in center, effectively reduce or prevent polished rod partial wear caused by by eccentric wear
Evil, avoids the abrasion of polished rod, extends the service life of polished rod；In addition, sealing ring is between pillar buoy and sealing drum, carry
High integrally-built sealing, prevents the generation of oil accident；Eccentric abrasion prevention formula blowout preventer of the present utility model also has
Have a safety feature, be simple in construction, be green, be easy for installation, being easy to carry.

Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of preventer of eccentric abrasion prevention formula of the utility model, as shown in figure 1, including pillar buoy 1, as shown in Figures 2 and 3,
Sealing drum 7 is socketed with outside pillar buoy 1, two parallel anti-deflection devices, each anti-deflection device bag are offered on the barrel of pillar buoy 1
The anti-bias hole 6 of at least three is included, anti-bias hole 6 is evenly distributed on the circumference of pillar buoy 1, there is adjustment spring 2, adjustment in each anti-bias hole 6
The one end of spring 2 connects the inwall of sealing drum 7, another end in contact connection ball 3 of adjustment spring 2, and ball 3 is exposed to pillar buoy 1
Inwall, the both ends inwalls connection profit sealer 4 of pillar buoy 1.
Anti-bias hole 6 is not more than the diameter of ball 3 in the aperture of the inwall of pillar buoy 1.
Some seal grooves 5 are offered on the outer tube wall of pillar buoy 1.
Seal groove 5 at least 3, and positioned at the both sides in every group of anti-bias hole 6.
The interior sealing of seal groove 5 connects sealing ring 8, and sealing ring 8 connects the inwall of sealing drum 7.
The both ends of sealing drum 7 offer taper button.
A kind of application method of the preventer of eccentric abrasion prevention formula of the present utility model is：
In use, then polished rod is positioned in pillar buoy 1, and in the axial direction, the both ends of sealing drum 7 are passed through into cone respectively
Shape button connection blowout prevention box, well head oil tubing string.It is corresponding to adjust spring if occurring during moving up and down to a direction eccentric wear
2 stress, while ball 3 will be promoted to act on polished rod, because polished rod moves just in the presence of ball 3；Polished rod moved up and down
Cheng Zhong, profit sealer 4 are tightly bonded polished rod, can remove the liquid on polished rod, prevent polished rod from being corroded, also function to simultaneously
The effect of sealing；Sealing ring 8 can strengthen its sealing on the outer wall of pillar buoy 1, additionally it is possible to damping.
A kind of effect of each part of preventer of eccentric abrasion prevention formula of the present utility model is as follows：
The outer wall of pillar buoy 1 offers seal groove 5, there is sealing ring 8 in seal groove 5, sealing ring 8 can reduce pillar buoy 1 with
Sealing drum 7 shakes, while can seal the gap between pillar buoy 1 and sealing drum 7.
Pillar buoy 1 has two groups of anti-bias holes 6, and every group of at least 3, anti-bias hole 6, every group of anti-bias hole 6 is evenly distributed on same circle
Zhou Shang, when polished rod does not have eccentric wear, polished rod uniform force in pillar buoy 1, when polished rod eccentric wear, eccentric wear direction stress can be made
It is larger, polished rod will be made to move just.
By the above-mentioned means, a kind of preventer of eccentric abrasion prevention formula of the present utility model, it is easy to solve polished rod in oil producing operation
The problem of eccentric wear, by the proportionality action of multiple adjustment springs and ball, the position of polished rod is aligned, effectively avoids polished rod
Abrasion, extend the service life of polished rod；In addition, sealing ring is between pillar buoy and sealing drum, overall structure is improved
Sealing, prevent oil accident；And have a safety feature, it is simple in construction, it is green, it is easy for installation to be easy to carry.
