Abstract
The present invention provides a kind of controllable bleeder, including main body, main body are non-magnet material；Sealing shroud, spring, regulation ring are equipped in main body successively, sealing shroud outer inclined-plane seals up the discharge orifice on the outer inclined-plane of main body, and spring is arranged between regulation ring and sealing shroud；It is designed with lock ball in lock ball slot in sealing shroud.The beneficial effects of the invention are as follows：Do not change latus rectum in tubing string, do not increase clearance volume, do not change tube column strength, weighted lever of the input with strong magnetic, bleeder could be opened only into tubing string, and open reliable.
Description
Technical field
The present invention relates to oil extraction in oil field, well workover kit technical fields, more specifically to a kind of controllable bleeder.
Background technology
Bleeder is most common kit on flow string, effect be when tubing string overhauls, can before lift pipe string
The oil water mixture in tubing string is released, grease pollutes well site ground during having prevented pipe, improves the work of operating worker
Make environment；
Currently used is hammering oil discharger and reciprocating oil releaser, further includes friction formula bleeder, build the pressure opening
Formula etc., due to being influenced by dirty in solidifying oil, wax deposition, tube column strength and tubing string, it is difficult to open bleeder, some bleeders change
Tubular column structure, if hammering oil discharger increases the clearance volume of reciprocating oil-well pump, reciprocating oil drain pump is easily opened, pipe
There is the deficiencies of undergauge in column.
Invention content
The present invention overcomes deficiencies in the prior art, provide a kind of controllable bleeder, are installed on oil well pump top, nothing
Undergauge, draining need to not only put into the exacerbation of the last one magnetic when tubing string maintenance needs draining into tubing string for tubing string holding during normal production
Bar can open this bleeder, and easy to use, bleeder does not turn off after opening.
The purpose of the present invention is achieved by following technical proposals.
A kind of controllable bleeder, including main body, the main body are non-magnet material；Sealing is equipped in the main body successively
Set, spring, regulation ring, the sealing shroud outer inclined-plane seal up the discharge orifice on the outer inclined-plane of the main body, and the spring setting exists
So that the sealing shroud remains stationary between the regulation ring and the sealing shroud；It is movable in lock ball slot in the sealing shroud
Equipped with lock ball.
Further, the sealing shroud is permeability magnetic material.
Further, the lock ball slot is to change the slot formed to narrow by width.
Further, the both sides of the discharge orifice are equipped with seal groove.
Further, sealing ring is equipped in the seal groove.
Beneficial effects of the present invention are：Do not change latus rectum in tubing string, do not increase clearance volume, do not change tube column strength,
Weighted lever of the input with strong magnetic, bleeder could be opened only into tubing string, and open reliable.

Specific implementation mode
Technical scheme of the present invention is further described below by specific embodiment.
In the following, refer to the attached drawing, makes a more thorough explanation the present invention, shown in the drawings of the exemplary implementation of the present invention
Example.However, the present invention can be presented as a variety of different forms, it is not construed as the exemplary implementation for being confined to describe here
Example.And these embodiments are to provide, it is of the invention full and complete to make, and will fully convey the scope of the invention to this
The those of ordinary skill in field.
The spatially relative terms such as "upper", "lower" " left side " " right side " can be used herein for ease of explanation, for saying
Relationship of the elements or features relative to another elements or features shown in bright figure.It should be understood that in addition in figure
Except the orientation shown, spatial terminology is intended to include the different direction of device in use or operation.For example, if in figure
Device is squeezed, and is stated as being located at other elements or the element of feature "lower" will be located into other elements or feature "upper".Cause
This, exemplary term "lower" can include both upper and lower orientation.Device, which can be positioned in other ways, (to be rotated by 90 ° or is located at
Other orientation), it can be interpreted accordingly used herein of the opposite explanation in space.
A kind of controllable bleeder as shown in Figure 1 and Figure 2, including main body, main body 1 are non-magnet material；It is set successively in main body 1
It is permeability magnetic material to have sealing shroud 2, spring 4, regulation ring 5, sealing shroud 2, and 2 outer inclined-plane of sealing shroud seals up on 1 outer inclined-plane 1.3 of main body
Discharge orifice 1.1, spring 4 is arranged between regulation ring 5 and sealing shroud so that 2 remains stationary of sealing shroud, and the power of spring 4 is more than pipe
The downward power of the sealing shroud 2 generated under 20Mpa pressure in column；It is designed with lock ball 3 in lock ball slot 2.1 in sealing shroud 2, locks
Ball groove 2.1 is to change the slot that is formed to narrow by width, and after 2 downlink of sealing shroud, lock ball 3 moves in lock ball slot 2.1, can will be close
Big envelope 2 is locked on the outer inclined-plane 1.3 of the main body 1, prevents 2 uplink of sealing shroud.
The both sides of discharge orifice 1.1 are equipped with seal groove 1.2, and sealing ring is equipped in seal groove 1.2.
The course of work：The bleeder is installed on oil well pump top in pumping pipe string, when oil well overhaul needs draining, rises
After sucker rod, a weighted lever is put into down-hole oil tube, club head is aggravated and one magnetic block is installed, when the magnetic block passes through the draining
When device, because main body 1 is un-conducted magnetic material, sealing shroud 2 is permeability magnetic material, and sealing shroud 2 is sucked by strong magnetic, therewith downlink,
Oil leak hole 1.1 is opened, and under the action of lock ball 3, is maintained the opening state of sealing shroud 2, is realized pipe column oil drainage.
One embodiment of the present invention has been described in detail above, but the content be only the present invention preferable implementation
Example should not be construed as limiting the practical range of the present invention.It is all according to all the changes and improvements made by the present patent application range
Deng should all still fall within the scope of the patent of the present invention.
