The situation of local damage, have impact on sealing effectiveness, so that the liquid in pipeline produces seepage, not only waste pumped (conveying) medium,
Also it have impact on the continuity of pipeline fluid media (medium).
Utility model content
In order to solve the above technical problems, the utility model provides a kind of flange assembly for liquid-transport pipe-line sealing.
The utility model is achieved by the following technical programs.
The utility model provides a kind of flange assembly for seal for pipe joints, including two annular flange dishes and is arranged on two
Annular gasket between individual annular flange dish, radial direction leak stoppage structure, the ring are provided with the mating surface of the ring flange and pad
Shape ring flange is connected as one pad by bolt assembly.
The radial direction leak stoppage structure includes：It is arranged at the ring flange inner peripheral surface and the close side end face of pad one
The transition breach of intersection and the transition projection for being arranged at the pad inner peripheral surface and its both sides face intersection.
The ring flange is additionally provided with boss close to pad side.
Transition breach on the ring flange matches with the transition projection on the pad.
The transition breach is consistent with shape, the size of transition projection.
The axial cross section shape of the transition breach is rectangle, triangle or sector.
The raised axial cross section shape of the transition is rectangle, triangle or sector.
The flange assembly is applied to the seal for pipe joints to conveying phosphoric acid,diluted.
The beneficial effects of the utility model are：Compared with prior art, the utility model changes method in the prior art
The structure of blue disk and annular gasket, by the transition breach and transition bulge-structure being separately positioned on ring flange and pad, add
The strong sealed connection to pipeline, in long-term use of flange assembly, when pad aging or when being corroded, it is not generation office
Portion is damaged and makes the fluid media (medium) seepage in pipeline, avoids the waste of fluid media (medium), maintains the continuity of pipeline.Should
Technical scheme has the advantages that simple in construction, cost is cheap.

Embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
As shown in Figure 1, Figure 2, Figure 6 shows, the utility model provides a kind of flange of seal for pipe joints for trandfer fluid medium
Component, including two annular flange dishes and the annular gasket 2 that is arranged between two annular flange dishes 1, ring flange 1 and pad 2
Mating surface at be provided with radial direction leak stoppage structure, annular flange dish 1 is connected as one pad 2 by bolt assembly.Using so
Radial direction leak stoppage structure, the sealed connection to pipeline is strengthened, in long-term use of flange assembly, when pad aging or by corruption
During erosion, it is not to produce local damage and make the fluid media (medium) seepage in pipeline, avoids the waste of fluid media (medium), maintain pipe
The continuity of road conveying.
As shown in Fig. 3, Fig. 4, Fig. 5, Fig. 7, Fig. 8, Fig. 9, radial direction leak stoppage structure includes：It is arranged at the inner peripheral surface of ring flange 1
With close to the side face intersection of pad 2 transition breach 3 and be arranged at the inner peripheral surface of pad 2 and its both sides end face phase
Transition projection 4 at friendship.The technical scheme for the radial direction leak stoppage structure being engaged using this transition breach 3 with transition projection 4, method
Structure all very simples of the transition breach of blue disk and annular gasket and transition projection, manufacturing cost is cheap, has higher warp
Ji property.
Further, it is preferable to which ring flange 1 is additionally provided with boss close to the side of pad 2, ring flange 1 is set close to the side of pad 2
Boss, during assembling, make the raised head face of ring flange 1 relative, fastened with bolt assembly, then gasket compression, further increase pair
The sealing of pipeline.
Further, the transition breach 3 on ring flange 1 matches with the transition projection 4 on pad 2.Transition breach 3 and mistake
Shape, the size for crossing projection 4 are consistent., can further optimization when transition projection 4 is consistent with shape, the size of transition breach 3
Blue component prevents the fluid spill and leakage in pipeline to the sealing effectiveness of pipeline.
Further, the axial cross section shape of preferably transition breach 3 is rectangle, triangle or sector, preferably transition
The axial cross section shape of projection 4 is rectangle, triangle or sector.
Further, it is preferable to which pad 2 is elastomeric material, there is higher resistance to corrosion using elastomeric material, can be adapted to
Convey the pipeline of multiple fluid.
Further, ring flange 1 is metal material, has higher corrosion resistance using the ring flange of metal material,
There is preferable machining property simultaneously, can be suitably used for the pipeline of multiple fluid.
Further, flange assembly is applied to the seal for pipe joints to conveying phosphoric acid,diluted.
When pipeline is connected and sealed using flange assembly provided by the utility model, make two ring flanges 1 first
Arranged opposite, pad 2 will be stated and be put between two ring flanges 1, make the fit structure of ring flange 1 and pad 2 complete to coordinate；So
Ring flange 1 is fastenedly connected with pad 2 using bolt connecting mode afterwards and is integrated.Using this technical scheme, due to making flange
The fit structure of disk and annular gasket carries out fitted seal, strengthens the effect of seal for pipe joints.
