Abstract
The utility model provides a stopper for oil pipeline and belongs to a leak stopping device. The stopper is provided with a hook-shaped pipeline clamping claw, the upper surface of the pipeline clamping claw is provided with a movable bar through a thread, the lower end of the movable bar is provided with a joint, and a protective plate is fixed on the upper surface of the pipeline clamping claw. The stopper for oil pipeline has simple structure, easy operation, high leak stopping speed, low cost and reliable leak stopping, and moreover, under the condition that the oil well conducts natural production and the oil transportation pipeline has oil transportation pressure inside, the utility model can block a leakage hole on the oil transportation pipeline and avoid loss due to production stop for leak stopping.
Description
Technical field
The utility model provides a kind of leakage-baffling device, the leakage-baffling device on especially a kind of petroleum transportation pipeline.
Background technique
The petroleum transportation pipeline in oil field (as single well pipeline, outside defeated main line) on, the lawless person often carries out drilling hole of oil stolen.At present, repair when stealing the hole, need the stopping production pressure release, then a pair of semicircle clamp of having dosed rubber is contained on the pipeline outer wall of stealing the place, hole, and pass through bolt.During operation, the rubber of clamp internal surface is easily movable, is difficult for aiming at the central position of clamp, and the surface of pipeline also needs to clean very totally, could seal stealing the hole.Not only operate cumbersomely, and be easy to clamp be pulled down, once more stolen by the lawless person.In addition, the stopping production pressure release not only influences ordinary production, and frequently stopping production can cause sand output well to shake out, and reduces oil well output, increases workover cost.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of petroleum pipeline leak stopping device, to improve convenience, the reliability of plugging operations.
The utility model is achieved in that petroleum pipeline leak stopping device, and it has hook-shaped pipeline claw, by screw thread motion bar is installed above the pipeline claw, and there is joint the motion bar lower end, also is fixed with backplate above the pipeline claw.
Adopt the petroleum pipeline leak stopping device of said structure, simple in structure, easy to operate, blocking speed is fast, cost is low, and leak stopping is reliable, can have in oil well ordinary production, oil transport pipeline under the situation of fuel transfer pressure, stop up the robber hole on the oil transport pipeline, the loss of having avoided the stopping production leak stopping to bring.
Description of drawings
Fig. 1 is the plan view of the utility model structure.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and using method.
As shown in drawings, the petroleum pipeline leak stopping device of the utility model, it has hook-shaped pipeline claw 1, by screw thread motion bar 3 is installed above the pipeline claw, and there is joint 3-1 the motion bar lower end, also is fixed with backplate 4 above the pipeline claw.
During use, on the joint of motion bar lower end, install the awl point 2 of irony.Then, the pipeline claw is stuck in pipeline 8 outsides of stealing the place, hole, makes the robber hole 7 on the sharp align with tube of awl, rotate motion bar then, its drive awl point is injected steal in the hole, will bore point by welding gun after being seated and be welded on the pipeline, block thereby will steal the hole.After having welded, this leak stopping device is taken off.Then, the unnecessary part on the awl point can be sliced off, whole leak stopping process is finished.
Joint can be the square projection below the motion bar, has and this projection corresponding groove on the awl point, and projection injects in the groove, realizes the installation of awl point.
Backplate plays the effect that stops that crude oil sprays to the operator.
Also has handle 5 on described motion bar 3 tops.Can rotate motion bar by handle.Certainly, motion bar also can be by rotations such as pipe wrench.
Claims (2)
