Abstract
The utility model discloses an interim plugging device of large diameter pipeline belongs to the auxiliary fixtures field that reaches before the dry operation of pipeline before pipeline jin kou connects, including the bottom plate, be fixed with the rubber boss on the bottom plate, the periphery of rubber boss is equipped with the installation claw on the bottom plate, and installs formation pipeline grafting chamber between claw and the rubber boss, is equipped with a plurality of fastening bolt that pipeline grafting chamber circumference distributes that follow on the installation claw. Adopt the utility model discloses a plugging device is to steel pipe mouth of pipe shutoff lighting and swiftly changing more, makes things convenient for constructor's operation and used repeatedly to reduce welding equipment's use, reduced construction cost, improved efficiency.
Description
Technical field
Auxiliary mould field before the utility model relates to pipeline Jin Kou connection and before pipeline drying operation, in particular to a kind of large diameter pipeline temporary plugging device.
Background technique
Oil, natural gas line are after main body has been welded, for ease of the pigging & diameter measuring of pipeline, pressure testing and dry construction, and complete at work pressure test, after pipeline carries out Jin Kou connection, all need line up to carry out temporary plugging, enter pipeline to have avoided foreign matter or free water.
At present, the many employings of the pipeline mouth of pipe plectane consistent with pipe diameter carries out the mode of welding, for large diameter pipeline, welding pipeline blind plate of full weld seam, at least needs the operating time of half an hour more than, also needs the construction equipment such as welding machine, power station just can complete, complex operation, efficiency is low.
Model utility content
The purpose of this utility model is to provide a kind of before pressure piping Jin Kou connects or after pipeline pressure test before drying, the conveniently large diameter pipeline temporary plugging device of line up shutoff, with solve existing welding plugging structure exist waste time and energy, inefficient problem.
For realizing the utility model object, the technological scheme adopted is: a kind of large diameter pipeline temporary plugging device, comprise base plate, base plate is fixed with rubber boss, on base plate, the outer of rubber boss is arranged with mounting jaw, and between mounting jaw and rubber boss, forming pipeline grafting chamber, mounting jaw is provided with multiple clamping bolt along pipeline grafting chamber circle distribution.
Further, the end periphery of described rubber boss is outer conical surface.
Further, described mounting jaw is made up of multiple multiple jaws that are outer at rubber boss, that circumferentially distribute, and jaw is arc-shaped, and each jaw arranges described clamping bolt.
Further, described jaw is four, and circumference is uniformly distributed.
Further, described rubber boss is integrally made up of the rubber ring on rubber plate and rubber plate, forms the described pipeline grafting chamber of one end open between the periphery of rubber ring and rubber plate and mounting jaw.
Further, described rubber boss is styrene butadiene rubber boss.
The beneficial effects of the utility model are:
1, when this plugging device uses, steel pipe inserts pipeline grafting chamber, rubber boss enters in steel tube end part, with steel pipe nozzle and fits tightly, tighten clamping bolt namely to achieve before oil, natural gas line Jin Kou connect and before pipeline drying the temporary plugging that steel pipe nozzle carries out, use simple, lighter in weight, convenient and swift, eliminate the operation that resettlement welding machine, power station etc. are more loaded down with trivial details, two people just can complete pipe plugging efficiently, reduce the labor intensity of workmen, more lighting and high-speeding, the operation of convenient construction personnel and reusing;
2, plugging device structure of the present utility model simply, easily realizes, and quick for installation easy, reliability is high, can realize the operation of different operating mode, varying environment, decrease the input of the construction equipments such as welding equipment, provide cost savings in a large number.And unitary design, normative and reasonable, constructability is on-the-spot when not adopting welding, and line up carries out temporary plugging, reduces construction sequence simultaneously, raises labour productivity, and solves the problem that free water enters pipeline preferably.
Accompanying drawing explanation
Fig. 1 is the sectional view of the large diameter pipeline temporary plugging device that the utility model provides;
Fig. 2 is the side view of plugging device shown in Fig. 1.
Embodiment
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1, Fig. 2 show the large diameter pipeline temporary plugging device that the utility model provides, comprise base plate 1, base plate 1 is fixed with rubber boss 2, on base plate 1, the outer of rubber boss 2 is arranged with mounting jaw 3, and between mounting jaw 3 and rubber boss 2, forming pipeline grafting chamber 4, mounting jaw 3 is provided with multiple clamping bolt along pipeline grafting chamber 4 circle distribution.
The end periphery of rubber boss 2 is outer conical surface, and namely end periphery has tapering, as shown in fig. 1, facilitates in smooth and easy insertion steel pipe 5 mouth of pipe.
Mounting jaw 3 is made up of multiple multiple jaws that are outer at rubber boss 2, that circumferentially distribute, and jaw is arc-shaped, and each jaw arranges described clamping bolt, namely between steel pipe 5 mouth of pipe access clamping bolt and rubber boss 2, tightens clamping bolt and realizes fixing.Jaw specifically can be four, and circumference is uniformly distributed.
Rubber boss 2 is integrally made up of the rubber ring 7 on rubber plate 6 and rubber plate 6, and form the described pipeline grafting chamber 4 of one end open between the periphery of rubber ring 7 and rubber plate 6 and mounting jaw 3, the end of rubber ring 7 is described outer conical surface.Rubber boss 2 specifically can be styrene butadiene rubber boss.
When using this plugging device, steel pipe 5 tube wall inserts between mounting jaw 3 and rubber ring 7 outer wall, and operator axially apply certain external force along steel pipe 5, makes to fit tightly with the rubber ring 7 of certain taper and steel pipe 5 mouth of pipe, tightening four clamping bolts of surrounding, reach the effect of line up shutoff.Like this plugging device is inserted steel pipe 5, the mouth of pipe seals by the rubber ring 7 of band certain taper completely, after tightening clamping bolt, avoids arbitrarily being taken off by people or stealing.Structure simply, easily realizes, and quick for installation easy, reliability is high, can realize the operation of different operating mode, varying environment, decrease the construction equipments such as welding equipment, save cost in a large number.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
