Description
Technical field
The utility model is related to a kind of multi-functional plugging devices of reducing, and in particular to a kind of multi-functional plugging device of reducing.
Background technology
Currently, when being blocked to pipeline tapping, generally use blocks air bag to be blocked, but blocking air bag can be by
It is coarse in pipeline and be punctured, it causes to block air bag and occurs to lose heart, and the material for blocking air bag will crack because meeting oil deformation, it is right
Safety in production brings very big hidden danger, and especially for the larger pipeline that is open, such case is particularly evident.Existing plugging device is only
The wellbore of single diameter can be sealed, universal performance is low.
Invention content
To solve the above-mentioned problems, the utility model proposes a kind of multi-functional plugging devices of reducing.
The technical solution of the utility model is：It is cased on the outside of a kind of multi-functional plugging device of reducing, including central tube, central tube
On the left of length 50 millimeters of hose assembly shorter than central tube, hose assembly under the top connection of setting, the setting of hose assembly right side
The lower contact that connector, central tube right end are arranged；The hose assembly includes casing play, inner glue layer, outer glue-line, packing element
Head；Through-hole is provided on the inner glue layer with central tube to be connected；It is provided with through-hole between the outer glue-line and inner glue layer.
Further, the center pipe end is provided with the pipe fitting of connection liquid cylinder pressure.
Further, sealing ring is provided between floating junction and central tube, the sealing ring is O-ring.
Further, the casing play is elastic stainless steel band.
Advantageous effect
A kind of multi-functional plugging device of reducing of the utility model, easily sets and unseals, and residual deformation is small, and pressure-bearing difference is big, fits
Ying Xingqiang, the salable large hole of small dimension plugging device, and it is not stringent to the requirement of wellbore rule degree, segment length is sealed, is had
Certain anchor itself ability, corrosion-resistant, service life is long, and by the liquid feeding pressure into oil pipe, liquid enters through inlet opening in packing element
Chamber insulates oil sets annular space, can adapt to the seal request of the wellbore of different-diameter to make packing element swell.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1- top connections, 2- hose assemblies, 3- central tubes, 4- floating junctions, 5- sealing rings, 6- lower contacts.
Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to a kind of multi-functional plugging device of reducing of the utility model.
As shown in Figure 1, a kind of multi-functional plugging device of reducing, including central tube 3,3 outside of central tube are cased with length and compare center
The lower contact 6 that is arranged on the right side of the top connection 1 that is arranged on the left of the hose assembly that 3 short 50 millimeter of pipe, hose assembly, hose assembly, in
The lower contact 6 of 3 right end of heart pipe setting；The hose assembly 2 includes casing play, inner glue layer, outer glue-line, packing element head；Institute
Through-hole is provided on the inner glue layer stated with central tube 3 to be connected；It is provided with through-hole between the outer glue-line and inner glue layer；Described
3 end of central tube is provided with the pipe fitting of connection liquid cylinder pressure；It is provided with sealing ring between the floating junction 4 and central tube 3
5, the sealing ring 5 is O-ring；The casing play is elastic stainless steel band.
Set process：The liquid feeding pressure out of oil pipe, liquid enter 2 inner cavity of packing element assembly through inlet opening, to make packing element assembly 2
It swells, insulates oil sets annular space.
Deblocking process：Oily overpressure is bled off, packing element assembly 2 withdraws deblocking.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation be not limited to the utility model although the utility model has been disclosed with preferred embodiment as above, it is any ripe
Professional and technical personnel is known, is not being departed within the scope of technical solutions of the utility model, when in the technology using the disclosure above
Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as being without departing from technical solutions of the utility model
Hold, any simple modification, equivalent change and modification made by the above technical examples according to the technical essence of the present invention, still
It is within the scope of the technical solutions of the present invention.
