Abstract
The utility model relates to an under-pressure welding and leakage blocking tool for pipelines, in particular to the tool for under-pressure welding operation. The under-pressure welding and leakage blocking tool for the pipelines comprises a U-shaped clamp. The outer surfaces of the two tail ends of the U-shaped clamp are of threaded structures. The corresponding portion of a pressing plate is provided with a through hole for the U-shaped clamp to pass through. The two tail ends of the U-shaped clamp penetrate through the through hole and are connected with fixing nuts in a threaded mode. A crank penetrates through the pressing plate and is connected with the pressing plate in a threaded mode. The tool is simple in structure, ingenious in design concept, convenient to use and maintain, and capable of carrying out all-dimensional under-pressure repair welding operation, and dealing with leakage accidents fast.
Description
Technical field
The utility model relates to a kind of pipeline blockage instrument, relates in particular to weld job instrument with pressure.
Background technique
Article one, the pipeline of sealing can exist and leak perforation under the effects such as oxidation that are subject to inner corrosion and outside.Fact proved, the leakage of seal arrangement is just many or few, light or heavy.The damage of the loss of material, equipment but leakage can cause the waste of the energy,, the pollution of environment even can cause fire, sets off an explosion, and causes stopping production, crisis personal safety.
In the past, after oil/water well pipeline perforation, owing to there being overbottom pressure in pipeline, generally need to bleed off pressure, the time that not only bleeds off pressure is long, affect crude oil production, and causes crude output loss and surface pollution in large area.
Summary of the invention
The utility model is exactly for the deficiencies in the prior art, and a kind of instrument that carries out pressure sealing operation is provided.
Pipeline seam leakage blinding instrument with pressure, comprise U-shaped card, two distal outer surface of described U-shaped card are worm structure, on pressing plate, relevant position is provided with the through hole that can pass U-shaped card, two ends of described U-shaped card are threaded with set screw nut through through hole, and crank passes pressing plate and is threaded with pressing plate.
Concrete, described pressing plate is provided with the hole matching with described crank, and internal surface of hole is worm structure.
Concrete, on described pressing plate, be provided with gland nut with crank matches, and on pressing plate, relevant position is provided with the through hole that can pass crank.
The utility model is simple in structure, and design concept is ingenious, easy to use, is convenient to safeguard, can carry out comprehensive repair welding operation with pressure, fast processing leakage accident.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
1 pipeline 2U type card 3 pressing plate 4 set screw nut 5 gland nut 6 crank 7 pads.
Embodiment
As shown in the figure, pipeline seam leakage blinding instrument with pressure, comprises U-shaped card, and two distal outer surface of described U-shaped card are worm structure, on pressing plate, relevant position is provided with the through hole that can pass U-shaped card, and two ends of described U-shaped card are threaded with set screw nut through through hole.
On described pressing plate, be fixedly installed gland nut and crank matches, and on pressing plate be provided with can be through the through hole of crank in relevant position.
During use, by U-shaped, be fastened on pipeline, then the end of U-shaped cutting ferrule passed to pressing plate and is adjusted to correct position with the set screw nut of screwing on.Then crank is screwed in gland nut, when crank withstands pipeline soon, pad is placed between crank and pipeline, continues precession crank, until the end of crank and pipeline dieback.Finally carry out weld job, pad is welded on to the seepage portion of pipeline.Complete after weld job, U-shaped card is taken off.The utility model is reusable.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characteristics is equal to replacement embodiment of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope that the utility model asks for protection.
