Abstract
The utility model provides a kind of double acting bleeder, including top connection, lower contact and sealing shroud, and top connection and lower contact pass through the interior concave station of top connection and the outer lug boss axial limiting of lower contact；Sealing shroud is fixed on lower contact top by shear pin, and by the shoulder axial limiting of top connection；Oil leak hole is equipped in top connection.The beneficial effects of the utility model are: structure is simple, latus rectum in tubing string is not changed, do not increase clearance volume, do not change tube column strength, sand face is visited by using tubing string or can open the weighted lever that the investment only into tubing string has dedicated opening tool in such a way that pump truck is suppressed, and bleeder can be opened easy to use.
Description
Technical field
The utility model relates to belong to oil extraction in oil field, well workover supporting tool technical field, more specifically to a kind of double
Act on bleeder.
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 double acting bleeder, is installed on oil well pump
Top, no undergauge, tubing string keeps not draining during normal production, when tubing string maintenance needs draining, need to only use pump truck to tubing string
Just this openable bleeder is inside suppressed, the mode that tubing string spy sand face can also be used opens this bleeder, and structure is simply easy to use.
The purpose of this utility model is achieved by following technical proposals.
A kind of double acting bleeder, including top connection, lower contact and sealing shroud, the top connection pass through with the lower contact
The interior concave station of the top connection and the outer lug boss axial limiting of the lower contact；The sealing shroud by shear pin be fixed on it is described under
Connector top, and by the shoulder axial limiting of the top connection；Oil leak hole is equipped in the top connection.
Further, the empty slot mobile for the sealing shroud is equipped between the lower contact and the top connection.
Further, the lower section that the oil leak hole is located at the sealing shroud is connected with the empty slot.
The utility model has the following beneficial effects: structure is simple, do not change latus rectum in tubing string, does not increase clearance volume, no
Change tube column strength, visit sand face by using tubing string or can be opened in such a way that pump truck is suppressed and only put into band into tubing string
There is the weighted lever of dedicated opening tool, bleeder can be opened easy to use.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the structure of utility model；
Fig. 2 is the state diagram of bleeder draining；
In figure:

2, sealing shroud；3, shear pin；4, lower contact；4.1, outer lug boss；5, empty slot.
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.
As shown in Figure 1, 2, a kind of double acting bleeder, including top connection 1, lower contact 4 and sealing shroud 2, top connection 1 is under
Connector 4 passes through the interior concave station 1.3 of top connection 1 and 4.1 axial limiting of outer lug boss of lower contact 4；Sealing shroud 2 is fixed by shear pin 3
In 4 top of lower contact, and by 1.1 axial limiting of the shoulder of top connection 1；It is equipped between lower contact 4 and top connection 1 for sealing shroud 2
Mobile empty slot 5, when shear pin 3 is cut sealing shroud 2 by pressure, sealing shroud 2 glides in empty slot 5, is equipped with and lets out in top connection 1
Oilhole 1.2, the lower section that oil leak hole 1.2 is located at sealing shroud 2 are connected with empty slot 5.
The course of work: the bleeder is installed on the oil well pump top in pumping pipe string and adopts when oil well overhaul needs draining
Pump truck is suppressed into tubing string, and when pressure reaches certain numerical value, shear pin 3 cuts 2 downlink of sealing shroud and exposes oil leak hole 1.2, tubing string
Inside and outside connection；Tubing string can also be transferred, using tubing string depth sand face, 3 shear pins is cut and exposes the inside and outside connection of the realization tubing string of oil leak hole 1.2.
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.
