Abstract
The utility model relates to a special hole sealing tee for pipeline, in particular to the technical field of pipeline transportation. The special hole sealing tee comprises a tee body(1), a blind plate(2), a sealing fitting(3).The sealing fitting(3)comprises a jaw(3-1) and a card board(3-2). The sealing fitting is fixed inside the upper end of the tee body(1) in a clamping mode through the card board. The blind plate is fixedly arranged on the upper end of the tee body(1) by a bolt. The card board(3-2) is placed inside the edge of the sealing fitting(3). The jaw(3-1) is placed on the outside of the edge of the sealing fitting(3). The jaw(3-1)is connected with the card board(3-2). The special hole sealing tee for pipeline utilizes the inner card board structure, the flange outside surface of the fitting is free from hidden leaking danger resulting from a locking pin and a locking ring hole, safety is improved, and operation risks are avoided.
Description
Technical field:
The utility model relates to a kind of shutoff threeway, is specifically related to the not special-purpose plugging holes threeway of stopping transportation of a kind of pipeline.
Background technique:
The plugging holes construction of oil, petrochemical industry conveyance conduit (the deoxygenation gas medium can not be constructed), gas transmission ﹠ distribution pipeline pipe network and water supply, heat supply pipeline requires not stopping transportation work of pipeline usually.Because construction operation and economic loss that stopping transportation causes and the harmful effect that the social production life is caused, there is potential safety hazard in traditional operation with pressure.Leakage hidden danger is caused easily because of old-fashioned pipe fitting latch-locking or lock ring hole in existing flange excircle surface.
The model utility content:
The purpose of this utility model provides the not special-purpose plugging holes threeway of stopping transportation of a kind of pipeline, holding plate type structure in it adopts, the leakage hidden danger that pipe fitting upper flange outer round surface is not caused because of old-fashioned pipe fitting latch-locking or lock ring hole improves Security, avoids operating risk.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises threeway body 1, blind plate 2, shutoff pipe fitting 3, shutoff pipe fitting 3 comprises claw 3-1 and clamp 3-2, it is inner that shutoff pipe fitting 3 is fixed on threeway body 1 upper end by clamp 3-2, and blind plate 2 is bolted on the upper end of threeway body 1.
Described clamp 3-2 is arranged on the inside, edge of shutoff pipe fitting 3, and claw 3-1 is arranged on the outside, edge of shutoff pipe fitting 3, and claw 3-1 is connected with clamp 3-2.
The utility model is fixed on inside, threeway body 1 upper end by stirring claw 3-1 so that clamp 3-2 ejects before installation, and then adds a cover blind plate 2 in threeway body 1 upper end, by bolt blind plate 2 is fixedly connected with threeway body 1 at last.
Holding plate type structure in the utility model adopts, the leakage hidden danger that pipe fitting upper flange outer round surface is not caused because of old-fashioned pipe fitting latch-locking or lock ring hole improves Security, avoids operating risk.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan view after Fig. 1 removes blind plate 2;
Fig. 3 is the structural representation of shutoff pipe fitting 3.
Embodiment:
Referring to Fig. 1-Fig. 3, this embodiment is by the following technical solutions: it comprises threeway body 1, blind plate 2, shutoff pipe fitting 3, shutoff pipe fitting 3 comprises claw 3-1 and clamp 3-2, it is inner that shutoff pipe fitting 3 is fixed on threeway body 1 upper end by clamp 3-2, and blind plate 2 is bolted on the upper end of threeway body 1.
Described clamp 3-2 is arranged on the inside, edge of shutoff pipe fitting 3, and claw 3-1 is arranged on the outside, edge of shutoff pipe fitting 3, and claw 3-1 is connected with clamp 3-2.
This embodiment is fixed on inside, threeway body 1 upper end by stirring claw 3-1 so that clamp 3-2 ejects before installation, and then adds a cover blind plate 2 in threeway body 1 upper end, by bolt blind plate 2 is fixedly connected with threeway body 1 at last.
Holding plate type structure in this embodiment adopts, the leakage hidden danger that pipe fitting upper flange outer round surface is not caused because of old-fashioned pipe fitting latch-locking or lock ring hole improves Security, avoids operating risk.
