Description
Technical field
The utility model belongs to oil gas downhole operation equipment technical field, more particularly to a kind of compact inverse well-flushing valve.
Background technology
In order to meet backwash well operations needs in oil exploitation, inverse well-flushing valve generally is installed in the production post that recovers the oil, instead
Flushing valve is check valve, it is allowed to which liquid pushes up opening ball valve upwards from the bottom of anti-flushing well, and liquid flows up from backwash valve；Well-flushing is made
After the completion of industry, ball valve is sitting on valve seat again, prevents the liquid in tubing string from being flowed downward out by backwash valve.
The flushing valve majority dimensional structure of oil recovery factory's application at present is larger, can not be applied in small space and complete well-flushing work
Industry；Underground environment is complicated, and part flushing valve can not finally complete clean-out service because the reasons such as long-term corrosion fail.
Utility model content
The purpose of this utility model is that solve the actual conditions that well-flushing is difficult in smaller space, there is provided a kind of compact
Inverse well-flushing valve, it can be used in small space, and sealing property is reliable.
Technical scheme provided by the utility model is：
A kind of compact inverse well-flushing valve, including valve body, through hole is in axial direction provided with the valve body, the through hole
One end is provided with spring base, and the other end is provided with ball seat, is provided with sealing ball and spring in the through hole, and the one of the spring
Hold connecting spring seat, other end connection ball sealer.
Preferably, the through hole has been arranged side by side two.
Preferably, inlet opening is radially offered on the valve body, the inlet opening is provided with ball seat with through hole
One end be connected.
Preferably, the spring base, ball seat, sealing ball and spring are made of stainless steel.
Preferably, sealing gasket is fixedly installed on the ball seat, so that ball seat is in contact with sealing gasket；It is and described close
Packing is made of quality of rubber materials.
Preferably, the inlaid hole of depression is provided with the ball seat, its section is in isosceles trapezoid, and the inlaid hole
Gradually increase from entrance point to inner width；Mosaic block is provided with the sealing gasket, its section is in isosceles trapezoid, described to inlay
Block is identical with the shape of inlaid hole and can be cooperating therewith.
The beneficial effects of the utility model embody in the following areas：
1st, the utility model physical dimension is smaller, can meet the requirement of small space clean-out service, solves small space well-flushing and makees
Many difficulties during industry；
When the 2nd, normally recovering the oil, connection up and down, oil jacket space is closed, does not influence to recover the oil；
3rd, stable performance is corrosion-resistant, can keep reliable sealing and service behaviour for a long time.
Brief description of the drawings
Fig. 1 is compact inverse well-flushing valve top view described in the utility model.
Fig. 2 be in Fig. 1 A-A to sectional view.
Fig. 3 is B-B direction sectional view in Fig. 1.
Fig. 4 is ball seat described in the utility model and sealing gasket matching relationship decomposition view.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model provides a kind of compact inverse well-flushing valve, including valve body 1, the valve
Two through holes in axial direction are arranged side by side in body 1, spring base 2 is provided with one end of the through hole, the other end is set
There is ball seat 3, ball sealer 4 and spring 5, one end connecting spring seat 2 of the spring 5 are provided with the through hole, the other end connects
Ball sealer 4 is connect, is that ball sealer 4 applies the power for being adjacent to ball seat 3 by spring base 2, by ball sealer 4 and ball seat 3 by through hole
Sealing.Inlet opening 6 is radially offered on valve body 1, and the inlet opening 6 is connected with the outside of ball seat 3.
The valve body 1, spring base 2, ball seat 3, ball sealer 4, spring 5 are process with high-quality stainless steel, stable performance
It is corrosion-resistant, reliable sealing and service behaviour can be kept for a long time.
Compact inverse well-flushing valve provided by the utility model using when lower section needed packer and lost circulation prevention device.Normal
In the case of, compact inverse well-flushing valve is connected up and down, and oil jacket space is closed, and does not influence the operation process such as oil recovery.When needing well-flushing
When, connecting pipeline is suppressed from sleeve pipe water filling, due to having packer and lost circulation prevention device, hydraulic pressure to pass through lateral inflow below flushing valve
Ball sealer 4 is opened on the top of hole 6, into oil pipe space, is further returned to ground and is completed clean-out service.
As shown in figure 4, in another embodiment, the one end being in contact on ball seat 3 with ball sealer 4 is provided with sealing gasket 7,
The quality of rubber materials of sealing gasket 7 is made, and the sealing gasket 7 is fixed with ball seat 3 by the way of inlaying, i.e., is set on ball seat 3
There is the inlaid hole 31 of depression, the section of the inlaid hole 31 is in isosceles trapezoid, and the isosceles trapezoid has two parallel sides, wherein
Short side is on the inner side end of ball seat 3, and long side is inside ball seat 3.Mosaic block 71 is provided with the sealing gasket 7, it is described to inlay
The section of block 71 is in isosceles trapezoid, and the isosceles trapezoid has two parallel sides, and wherein short side is connected with sealing gasket 7.It is described
The shape of mosaic block 71 and inlaid hole 31 is completely just as enabling mosaic block 71 to be embedded into inlaid hole 31, by strong during installation
Mosaic block 71 is expressed in inlaid hole 31 by row fashion of extrusion, because the opening of inlaid hole 31 is difficult to than internal pinch, mosaic block 71
Taken out from inlaid hole 31, it is achieved thereby that sealing gasket 7 and ball seat 3 are tightly fastened.Because sealing gasket 7 is elastomeric material, sealing
Ball 4 is in contact with sealing gasket 7, can play better seal effect.
The utility model is simple in construction, and size is smaller, the clean-out service that can be applied in small space, stable performance corrosion resistant
Erosion, reliable sealing and service behaviour can be kept for a long time.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization.It can be applied to various suitable fields of the present utility model completely.For those skilled in the art,
Other modification is easily achieved.Therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new and shown here as the legend with description.
