Abstract
The utility model provides a kind of controllable bleeder, including main body, and main body is non-magnet material；It is successively arranged sealing shroud, spring in main body, adjusts ring, sealing shroud outer inclined-plane seals up the discharge orifice on the outer inclined-plane of main body, and spring setting is being adjusted between ring and sealing shroud；Design has lock ball in lock ball slot in sealing shroud.The beneficial effects of the utility model are: not changing latus rectum in tubing string, do not increase clearance volume, do not change tube column strength, investment has the weighted lever of strong magnetic only into tubing string, and bleeder could be opened, and opens reliable.
Description
Technical field
The utility model relates to oil extraction in oil field, well workover supporting tool technical field, controllably let out more specifically to one kind
Oily device.
Background technique
Bleeder is most common supporting tool on flow string, effect be in tubing string maintenance, can before lift pipe string
The oil water mixture in tubing string is released, has prevented grease during pipe from polluting to well site ground, has improved 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. is difficult to open bleeder, some bleeders change due to being influenced by dirty in solidifying oil, wax deposition, tube column strength and tubing string
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.
Summary of the invention
The utility model overcomes deficiency in the prior art, provides a kind of controllable bleeder, is installed on oil well pump
Portion, no undergauge, tubing string keeps not draining during normal production, and when tubing string maintenance needs draining, the last one need to be only put into tubing string
Magnetic weighted lever is with regard to this openable bleeder, and easy to use, bleeder does not turn off after opening.
The purpose of this utility model is achieved by following technical proposals.
A kind of controllable bleeder, including main body, the main body are non-magnet material；Sealing is successively arranged in the main body
Set, spring adjust ring, and the sealing shroud outer inclined-plane seals up the discharge orifice on the outer inclined-plane of the main body, and the spring setting exists
So that the sealing shroud is remain stationary between the adjusting ring and the sealing shroud；It is movable in the 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 two sides of the discharge orifice are equipped with seal groove.
Further, sealing ring is equipped in the seal groove.
The utility model has the following beneficial effects: not changing latus rectum in tubing string, do not increase clearance volume, it is strong not change tubing string
Degree, investment has the weighted lever of strong magnetic only into tubing string, and bleeder could be opened, and opens reliable.
Detailed description of the invention

Specific embodiment
The technical solution of the utility model is further described below by specific embodiment.
In the following, being made a more thorough explanation with reference to attached drawing to the present invention, shown in the drawings of exemplary implementation of the 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, to keep the present invention full and complete, and it 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" may 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 successively set in main body 1
There are sealing shroud 2, spring 4, adjust ring 5, sealing shroud 2 is permeability magnetic material, and 2 outer inclined-plane of sealing shroud seals up on the outer inclined-plane 1.3 of main body 1
Discharge orifice 1.1, the setting of spring 4 adjusting between ring 5 and sealing shroud so that sealing shroud 2 is remain stationary, and the power of spring 4 is greater than pipe
The downward power of the sealing shroud 2 generated under 20Mpa pressure in column；Design has lock ball 3 in the 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 two sides of discharge orifice 1.1 are equipped with seal groove 1.2, are equipped with sealing ring 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 utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
