Abstract
A sealing pipeline connecting device comprises an outer sleeve nut, a spherical washer, a damping pad, a washer, a spherical pipe connector, a spherical bush, a bush, a first pipe connector, a second pipe connector, a first sealing ring, a second sealing ring and an elastic expanding ring. The first pipe connector, the second pipe connector and the outer sleeve nut are tightened, the bush is connected with the spherical bush in a matched mode, the damping pad is arranged between the spherical washer and the washer, the spherical pipe connector is respectively connected with the spherical washer and the first pipe connector in a matched mode, the spherical bush is respectively connected with the spherical washer and the second pipe connector in a matched mode, the first sealing ring is in transition fit with the bush, the second sealing ring is of a three-section structure, and the elastic expanding ring guarantees the fact that the second sealing ring and the bush are in tight contact. The sealing pipeline connecting device has the advantages that cost is lowered, sealing reliability is improved, pipelines are adjustable during mounting, pipeline correcting work is greatly reduced, assembling is easy, and deformation generated by cold-hot state pipelines can be absorbed.
Description
Technical field
The utility model relates to pipeline jointing construction, particularly a kind of sealing pipeline connection set.
Background technique
Gas turbine need to adopt diameter greater than 100mm Large Diameter Pipeline bleed line high-temperature high-pressure fuel gas to be discharged fast usually.When the bleed line of Large Diameter Pipeline adopted metallic hose and be connected the pipe joint connection, metallic hose life and reliability under vibration and hot environment can't meet the demands; When adopting seamless steel pipe and be connecteding the pipe joint connection, the Large Diameter Pipeline seamless steel pipe not only is difficult for the school type to be installed, and has again cold and hot deformation problem.Therefore the pipeline connecting device that the adjustable while can absorb again the cold and hot distortion need to a kind ofly can be installed.
The model utility content
The purpose of this utility model is in order to improve the reliability of line seal, reduces when installing the school type of pipeline, can absorb the amount of deformation of cold and hot pipeline, and the spy provides a kind of sealing pipeline connection set.
The utility model provides a kind of sealing pipeline connection set, it is characterized in that: described sealing pipeline connection set comprises, cap nut 1, spherical washer 2, damping pad 3, packing ring 4, spherical fitting head 5, spherical bushing 6, lining 7, the first pipe joints 8, the second pipe joint 9, the first seal ring 10, the second seal rings 11, spring piston ring 12;
Wherein: the first pipe joint 8, the second pipe joint 9 are tightened with cap nut 1, and lining 7 is connected with spherical bushing 6, have guaranteed that namely having certain compensation rate at the pipeline axial direction when pipeline is installed can absorb again the amount of deformation that the cold and hot pipeline produces.Damping pad 3 is installed between spherical washer 2 and the packing ring 4, spherical fitting head 5 is connected with spherical washer 2 and the first pipe joint 8 respectively, spherical bushing 6 is connected with spherical washer 2 and the second pipe joint 9 respectively, the first seal ring 10 is transition fit with lining 7, the second seal ring 11 is three-stage structure, and spring piston ring 12 is guaranteed the second seal ring 11 and lining 7 close contacts.
Described lining 7 is with flat segments, and relative spherical bushing 6 free-extensions of flat segments.
Advantage of the present utility model:
Sealing pipeline connection set described in the utility model reduces cost, improves the reliability of sealing, and pipeline is adjustable when installing, and has reduced greatly the work to pipeline school type, and assembling is easily simple.The joint of pipeline one end is the flat segments seal form, has guaranteed to absorb the amount of deformation that the cold and hot pipeline produces.
