Abstract
The invention discloses a movable flange structure used for pipeline connection. The movable flange structure comprises a unit device lead-out pipe, a sealing rubber strip, an annular plate, a movable flange, a foundation buried pipe, a standard flat-welded steel pipe flange, bolts and nuts, and is characterized in that the unit device lead-out pipe and the standard flat-welded steel pipe flange are fixedly connected with each other; the foundation buried pipe is arranged outside the unit device lead-out pipe; the foundation buried pipe is connected with the unit device lead-out device through the flanges; the movable flange is arranged at the lower end of the standard flat-welded steel pipe flange; the annular plate is arranged between the movable flange and the foundation buried pipe and is pressed by the movable flange; and the bolts are arranged between the movable flange and the standard flat-welded steel pipe flange. The movable flange structure can be suitable for being installed and used in pipeline connection of multiple units, staggered movable flanges in pipeline connection can be adjusted, the requirements for unit pipeline connection and sealing can be met, and the movable flange structure has the beneficial effects of being good in sealing performance, simple and reasonable in structure and convenient to install and adjust.
Description
Technical field
The present invention relates to technical field of hydraulic generators, particularly relate to a kind of pipeline connection flange arrangement alive.
Background technique
At present, flange is flange plate again, for connecting between pipeline, or for carrying out the part be connected between pipeline with valve, is connected to the end of pipe fitting.When units' installation; usually the situation of drawing pipeline and being connected with basic built-in pipe can be run in unit equipment; due to base concrete build time; certain deviation can be there is in pre-buried pipeline position dimension; and unit pipeline is all welded structure or is rigidly connected, cannot adjust, thus there will be unit equipment extraction pipeline and pre-buried pipe interface off(-)center phenomenon; now as connected with paired standard downhand welding steel pipe flanges, be difficult to closing.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, provide a kind of pipeline connection flange arrangement alive, the present invention can be useful in during multiple stage unit pipeline connects and install and use, the flange alive of pipeline connecting staggered can be regulated, meet unit pipeline to connect and seal request, there is good airproof performance, simple and reasonable and be convenient to the advantage of mounting and adjusting.
Technological scheme of the present invention is: a kind of pipeline connection flange arrangement alive, comprise: unit equipment fairlead, sealing rubber strip, ring flat-plate, flange alive, basis built-in pipe, standard downhand welding steel pipe flanges, bolts and nuts, it is characterized in that: described unit equipment fairlead and described standard downhand welding steel pipe flanges are mutually permanently connected, described unit equipment fairlead is outside equipped with basic built-in pipe, described basic built-in pipe and described unit equipment fairlead pass through Flange joint, described standard downhand welding steel pipe flanges lower end is provided with flange alive, ring flat-plate is provided with between described flange alive and basic built-in pipe, described flange screw ring flat-plate alive, bolt is provided with between described flange alive and standard downhand welding steel pipe flanges, be inter-connected via a bolt joint between described flange alive and described standard downhand welding steel pipe flanges, described bolt is provided with nut, sealing rubber strip is provided with between described flange alive and standard downhand welding steel pipe flanges.
Further, described close rubber strip is nitrile butadiene rubber bar.
Beneficial effect of the present invention is:
1. the present invention can be useful in during multiple stage unit pipeline connects and install and use, and meets unit pipeline and connects and seal request, has good airproof performance, simple and reasonable and be convenient to the advantage of mounting and adjusting.
2. sealing rubber strip of the present invention is nitrile butadiene rubber bar, and nitrile butadiene rubber has fabulous oil resistance and water resistence, simultaneously tightness, and wear resistance and heat resistance are also higher.
3. the present invention is owing to leaving certain interval between ring flat-plate and flange alive, when two pipelines have dislocation phenomenon, carries out adjustment two pipeline center by this gap, thus is convenient to mutually align closing between standard downhand welding steel pipe flanges with flange alive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, unit equipment fairlead 2, sealing rubber strip 3, ring flat-plate
4, to live flange 5, basic built-in pipe 6, standard downhand welding steel pipe flanges

Embodiment
Below in conjunction with accompanying drawing, brief description is made to the specific embodiment of the present invention.
As shown in Figure 1, a kind of pipeline connects with flange arrangement of living, comprise: unit equipment fairlead 1, sealing rubber strip 2, ring flat-plate 3, flange 4 alive, basis built-in pipe 5, standard downhand welding steel pipe flanges 6, bolt 7 and nut 8, it is characterized in that: described unit equipment fairlead 1 is mutually permanently connected with described standard downhand welding steel pipe flanges 6, described unit equipment fairlead 1 is outside equipped with basic built-in pipe 5, described basic built-in pipe 5 passes through Flange joint with described unit equipment fairlead 1, described standard downhand welding steel pipe flanges 6 lower end is provided with flange 4 alive, ring flat-plate 3 is provided with between described flange alive 4 and basic built-in pipe 5, described flange alive 4 compresses ring flat-plate 3, bolt 7 is provided with between described flange alive 4 and standard downhand welding steel pipe flanges 6, be interconnected by bolt 7 between described flange alive 4 and described standard downhand welding steel pipe flanges 6, described bolt 7 is provided with nut 8, sealing rubber strip 2 is provided with between described flange alive 4 and standard downhand welding steel pipe flanges 6.
Structure of the present invention is simple, the flange alive of pipeline connecting staggered can be regulated, be welded to each other between standard downhand welding steel pipe flanges and unit equipment fairlead, mutually to weld between ring flat-plate and basic built-in pipe and must not seepage, flange screw ring flat-plate alive, and fastening with standard pipe flange screw bolt and nut, live between flange and standard downhand welding steel pipe flanges and ring flat-plate and seal with sealing rubber strip, thus reach the object of leakproof.Owing to leaving certain interval between ring flat-plate and flange alive, when two pipelines have dislocation phenomenon, carry out adjustment two pipeline center by this gap, thus be convenient to mutually align closing between standard downhand welding steel pipe flanges with flange alive.
Above embodiment, only in order to technological scheme of the present invention to be described, can not limit scope of the present invention with this; To the amendment that the technological scheme described in foregoing embodiments is carried out, or to the equivalent replacement that wherein portion of techniques feature is carried out, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technological scheme, all should still remain within the scope of the patent.
