Pipeline instrument valve hole driller with pressureTechnical field
A kind of pipeline punching device under pressure is the utility model is related to, more particularly to a kind of pipeline instrument valve press and open holesDevice.
Background technology
The pipeline tapping of instrument valve, which is operated in actual production, to happen occasionally, and is that manometer is in oil transportation production firstInstrument the most universal, and the installation of all instrument is required for pipeline tapping operation, particularly renovates transformation in the hidden danger of pipelinePeriod, often have in the perforate operation of instrument pressure port on pipeline and in-service pipeline of not going into operation.
The effect that the perforate of instrument valve is even more important is embodied in emergency repair aspect.Pipeline " paraffin blockage " and " solidifying pipe " eventIt is production accident more serious in oil transportation production.Once " paraffin blockage " and " solidifying pipe " accident occurs, it is often the case that take " boostingExtrude " and " pipe is changed in closure " method.The most key link is promptly and accurately to judge thing in the disposal process of such accidentTherefore specific pipeline section.General way is to open instrument hole in doubtful pipeline many places, and installs manometer.Then operation oil transfer pump carriesHigh pipeline pressure.Now pass through the pressure change of many places manometer, it is possible to accurately locking accident pipeline section.Due toThe Temperature Field of the Near Pipelines of " paraffin blockage " and " solidifying pipe " can be eliminated slowly, once without Temperature Field, accident will be serious rapidlyTo solidifying pipe, it can only now block and change pipe, this will bring immeasurable loss to enterprise.
The content of the invention
The purpose of this utility model is aiming at drawbacks described above existing for prior art, there is provided a kind of pipeline instrument valve bandPress hole making drill, it can be ensured that Temperature Field is less impacted, completes the perforate operation in instrument hole, and quick lock in thing in a short timeSend out pipeline.
Its technical scheme is：Including valve connection sleeve pipe（1）, feed sleeve（2）, drilling rod（3）, side valve door（4）, connector（5）, plug（6）, the valve connection sleeve pipe（1）One end be provided with connector（1.1）, in connector（1.1）Outside connectionSide valve door（4）, in connector（1.1）Inner chamber be provided with internal thread, with pipeline（9）The pipe nipple of welding（7）It is connected through a screw thread, instituteState valve connection sleeve pipe（1）Outside be cased with feed sleeve（2）, the feed sleeve（2）It is interior to be provided with drilling rod（3）, drilling rod（3）'sOne end is provided with drill bit, and the other end is provided with rotating handles, and passes through plug at rotating handles（6）It is tightly connected.
Above-mentioned pipe nipple（7）It is provided with main valve（8）.
Above-mentioned feed sleeve（2）One end be provided with groove, pass through groove and connector（5）It is connected；Feed sleeve（2）The other end be provided with plug groove, with plug be connected.
Above-mentioned plug（6）With feed sleeve（2）Between be provided with sealing ring.
The beneficial effects of the utility model are：Stopping transportation pressure perforate is realized, and the maximum pressure for testing proof canTo reach 3.6 Mpa, operating pressure is typically in 3.6 below MPa during pipeline perforate）.The exploitation of the achievement thoroughly solves pipelineThe dangerous problem of perforate, but also crude oil seepage or injection caused by Tapping procedures can be avoided.The emergency repair energy of maintenance crewTherefore power has also obtained certain raising, grasped pipeline paraffin blockage or solidifying pipe accident handling quickly determines the preferable of accident pipeline section positionMethod.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model；
Accompanying drawing 2 is that the utility model applies schematic diagram in pipeline；
In figure：Valve connection sleeve pipe 1, feed sleeve 2, drilling rod 3, side valve door 4, connector 5, plug 6, pipe nipple 7, main valve8th, pipeline 9, connector 1.1.
Embodiment
With reference to attached Fig. 1 and 2, the utility model will be further described：
The utility model includes valve connection sleeve pipe 1, feed sleeve 2, drilling rod 3, side valve door 4, connector 5, plug 6, instituteThe one end for stating valve connection sleeve pipe 1 is provided with connector 1.1, in the outside connecting side valve 4 of connector 1.1, in connector 1.1Inner chamber is provided with internal thread, and the pipe nipple 7 welded with pipeline 9 is connected through a screw thread, and the outside of the valve connection sleeve pipe 1 is cased with feedSleeve 2, the feed sleeve 2 is interior to be provided with drilling rod 3, and one end of drilling rod 3 is provided with drill bit, and the other end is provided with rotating handles, and rotatesIt is tightly connected at handle by plug 6.
Wherein, pipe nipple 7 is provided with main valve 8, and one end of above-mentioned feed sleeve 2 is provided with groove, passes through groove and connector 5It is connected；The other end of feed sleeve 2 is provided with plug groove, is connected with plug.
In addition, sealing ring is provided between plug 6 and feed sleeve 2.
It is of the present utility model as follows using step：
1st, valve connection sleeve pipe 1 is connected with the pipe nipple 7 being arranged on pipeline 9 by thread seal；
2nd, broach shell cylinder 2 is rotated into, drives drilling rod 3 to push ahead, until drill bit presses close to pipeline 9；
3rd, by rotary handle rotary drill rod 3 and coordinate feed sleeve drive drill bit perforate；
4th, perforate progress is confirmed by the side valve door 4 in valve connection sleeve pipe, can be from side valve door if perforate successTrickle, the main valve 8 of pipeline installation is closed after perforate success is confirmed, perforate is completed, removes hole making drill, then pipeline is installedInstrument, such as pressure gauge.
For the work in every performance for suppressing hole making drill that fully checking is developed, it is blind dead using homemade two to rob maintenance crewPipeline section has carried out water filling and suppressed, up to line pressure to 3.6MPa.Pipeline perforate experiment is carried out in this case.From start beatMill pipeline is completed to final perforate, has only been used 20 minutes, and whole process just only has two people to operate completion.It is important to be mentioned thatThere is no any water to overflow in perforate operation process, it is sufficient to demonstrate the instrument hole with pressure drilling tool newly researched and developed and possess peaceEntirely, the characteristics of quick, easy to operate.
It is described above, only it is preferred embodiment of the present utility model, any those skilled in the art may profitEquivalent technical scheme is changed the utility model or is revised as with the technical scheme of above-mentioned elaboration.Therefore, foundationAny simple modification or substitute equivalents that the technical solution of the utility model is carried out, belong to the greatest extent the requires of the utility model protectionScope.
