Description
Technical field
The present invention relates to pipeline maintenance device field, particularly relate to a kind of oil pipe leak stoppage checkpost.
Background technique
In oilfield exploitation transport production process, there is the pipeline of various different size, but owing to being subject to the impact of Environmental Conditions and preparation process, general pipeline can be subject to corrosion in various degree after using 3-5, there will be the phenomenons such as pipe perforation and cause crude oil to leak, while befouling environment, cause unnecessary economic loss to oil field.In addition, the destruction that some stolen molecules carry out without restraint in order to steal crude oil from oil transport pipeline to oil transport pipeline, causes pipeline leakage, has a strong impact on crude oil yield and manufacturing schedule.
When the pipeline for oil transportation goes wrong, traditional method for repairing and mending is first place mat one block of rubber plate in the place of pipe perforation, and then two pieces of clamps with radian are withheld at diagonal angle on the position of pipe perforation, and with bolt tightening, until pipeline no longer leaks.But such maintenance mode has the following disadvantages, the repairing time is longer, generally need 2-3 hour, and be difficult to once repair successfully, once repair and need many people to coact and carry out, the manpower and materials of at substantial, and repair after working life shorter, be easy to again seepage occur.
Meanwhile, leak stoppage checkpost of the prior art generally can only realize the effect of leak stopping, and effective row pressure of having no idea adds loaded down with trivial details requisition procedure of getting angry, had a strong impact on the raising of oil extraction efficiency.
Therefore, a kind of oil pipe leak stoppage checkpost is needed in market badly, when pipeline starts a leak, can carry out Rapid-Repair, and can carry out effective row pressure.
Summary of the invention
The object of the invention is to, a kind of oil pipe leak stoppage checkpost is proposed, can repair leak fast when pipeline starts a leak, easy to use, to solve leak stoppage checkpost in use inconvenient operation in prior art, the problem that excessive cannot the discharge of pressure of pipe interior and the pipeline caused repeatedly leak.
For reaching this object, the present invention by the following technical solutions:
A kind of oil pipe leak stoppage checkpost, comprise buckling body and lower buckling body, the first end of described upper buckling body and the first end of lower buckling body link together by twisted axis is rotating, and described upper buckling body and lower buckling body are provided with the fixed hole for fixing afterburning screw mandrel; One end of described afterburning screw mandrel is provided with arc plug, and described arc plug inside is provided with L-type row pressure pipeline, and the described first end of row pressure pipeline is connected with the leak on oil pipe, and the second end of described row pressure pipeline is provided with bolt and is closed by described row pressure pipeline.
Further, be provided with sealing gasket between described arc plug and described oil pipe, described sealing gasket is made by nitrile butadiene rubber vulcanizing material.
Further, be detachably fixed together by joint between one end of described afterburning screw mandrel and arc plug; Be provided with screw thread in described joint, described afterburning screw mandrel is connected with described arc plug by screw thread.
Further, the other end of described afterburning screw mandrel is provided with handle, and described handle is used for tightening described afterburning screw mandrel.
Preferably, described upper buckling body and lower buckling body are respectively provided with 3 fixed holes, and the angle between adjacent described fixed hole is 60 °.
Further, linked together by clamping bolt between the second end of described upper buckling body and the second end of lower buckling body.
Further, the size of the first end of described row pressure pipeline is greater than the size of described row pressure pipeline second end.
Beneficial effect of the present invention is: structure of the present invention is simple, easy to use, be easy to dismounting, the pressure difference inside and outside oil pipe can also be reduced by the opening and closing controlling bolt while leak stopping is carried out to tubing leak place, effectively prevent from causing crude oil leakage because oil pipe internal pressure is excessive.
Carry out leak stopping because the present invention is provided with afterburning screw mandrel to tubing leak place, the power of applying acts directly on leakage part, and leak stopping accurately, rapidly, firmly; Effectively can accelerate maintenance efficiency, greatly save engineering time, and only need two people just can complete maintenance operation, save a large amount of human and material resources, economic benefit is better.
The present invention is provided with the sealing gasket made by nitrile butadiene rubber vulcanizing material between oil pipe and arc plug, the while that sealing effect being better, can effectively prevent crude oil to its oxidation.
