By adopting technique scheme, annular is all arranged in the first convex edge and the second convex edge, in the time that connecting tube is socketed on pipeline, pipeline has the first convex edge axially preventing its relative connecting tube play with the second convex edge, at axial clearance inner circumference some apex sealing strips that distribute, can be in the effect of radially playing fixing tube and connecting tube, effectively prevent rotating in a circumferential direction of the relative flange of pipeline, the first convex edge, cooperation between the second convex edge and apex sealing strip three can be played the effect of closed conduit and connecting tube, strengthen the sealing of pipeline and connecting tube at circumferential and axial simultaneously, reasonable in design.
Further improvement as technique scheme: the external diameter of the external diameter of described the first convex edge and the second convex edge is suitable.
By adopting technique scheme, the external diameter of the first convex edge and the second convex edge can allow the gap connecting between pipeline and connecting tube more even when suitable, and fluid is not easy seepage from the high low gap of the first convex edge and the second convex edge.
The utility model is further set to: the height of the relative connecting tube inwall of described apex sealing strip is suitable with the height of the first relative connecting tube inwall in convex edge.
By adopting technique scheme, the height of the relative connecting tube inwall of apex sealing strip is consistent with the height of the first relative connecting tube inwall in convex edge, also just consistent with the height of the second relative connecting tube inwall in convex edge, between such the first convex edge, the second convex edge and apex sealing strip three, do not have rugged ladder and exist, fluid is not easy seepage between gap.
The utility model is further set to: described flange plate is distributed with some contiguous blocks and some shape quantity suitable connecting groove with it away from one end even circumferential of connecting tube.
By adopting technique scheme, connecting tube and connecting groove are set, while docking between the flange plate of two piping flanges like this, the contiguous block of any one in two flanges will be absorbed in connecting groove, between multiple, fasten, then by the flange plate of two docking after the fastening pieces such as bolt are fastening, between two flange plate, be not easy radial misalignments, and in external force during in circumferential twisting flange, between flange plate, except fastening piece fastening, also have the grafting of contiguous block and connecting groove, fastening piece is not easy fracture and damages.
The utility model is further set to: described flange plate is distributed with two contiguous blocks and two connecting grooves away from one end even circumferential of connecting tube, and described contiguous block and connecting groove interval arrange.
By adopting technique scheme, when two contiguous blocks and connecting groove interval arrange, not only easy to process, and convenient in the time of design and installation hole, in the time of docking two flange, be more prone to.

Embodiment
Referring to figs. 1 through Fig. 3, the utility model piping flange embodiment is described further.
A kind of novel pipeline flange, comprise flange plate 2 and one end connecting tube 1 that one is connected with it, on described flange plate 2, offer some mounting holes 21, described connecting tube 1 convexes with the first convex edge 11 and the second convex edge 12 that all arrange ringwise away from the inwall of flange plate 2 one end, between described the first convex edge 11 and the second convex edge 12, be provided with axial clearance 14, described connecting tube 1 is distributed with some apex sealing strips 13 in the inwall even circumferential at axial clearance 14 places, the axis of the axis of described apex sealing strip 13 and connecting tube 1 be arranged in parallel, conflict and be connected with the first convex edge 11 and the second convex edge 12 respectively in the axial two ends of described some apex sealing strips 13.
By adopting technique scheme, annular is all arranged in the first convex edge 11 and the second convex edge 12, in the time that connecting tube 1 is socketed on pipeline, pipeline has the first convex edge 11 axially preventing its relative connecting tube 1 play with the second convex edge 12, at axial clearance 14 inner circumferences some apex sealing strips 13 that distribute, can be in the effect of radially playing fixing tube and connecting tube 1, effectively prevent rotating in a circumferential direction of the relative flange of pipeline, the first convex edge 11, cooperation between the second convex edge 12 and apex sealing strip 13 threes can be played the effect of closed conduit and connecting tube 1, strengthen the sealing of pipeline and connecting tube 1 at circumferential and axial simultaneously, reasonable in design.
The external diameter of the external diameter of described the first convex edge 11 and the second convex edge 12 is suitable.By adopting technique scheme, the external diameter of the first convex edge 11 and the second convex edge 12 can allow the gap connecting between pipeline and connecting tube 1 more even when suitable, and fluid is not easy seepage from the high low gap of the first convex edge 11 and the second convex edge 12.
The height of described apex sealing strip 13 relative connecting tube 1 inwalls is suitable with the height of the first relative connecting tube 1 inwall in convex edge 11.By adopting technique scheme, the height of apex sealing strip 13 relative connecting tube 1 inwalls is consistent with the height of the first relative connecting tube 1 inwall in convex edge 11, also just consistent with the height of the second relative connecting tube 1 inwall in convex edge 12, between such the first convex edge 11, the second convex edge 12 and apex sealing strip 13 threes, do not have rugged ladder and exist, fluid is not easy seepage between gap.
Described flange plate 2 is distributed with some contiguous blocks 22 and some shape quantity suitable connecting groove 23 with it away from one end even circumferential of connecting tube 1.By adopting technique scheme, connecting tube 1 and connecting groove 23 are set, while docking between the flange plate 2 of two piping flanges like this, the contiguous block 22 of any one in two flanges will be absorbed in connecting groove 23, between multiple, fasten, then by the flange plate of two docking 2 after the fastening pieces such as bolt are fastening, between two flange plate 2, be not easy radial misalignments, and in external force during in circumferential twisting flange, between flange plate 2, except fastening piece fastening, also have the grafting of contiguous block 22 and connecting groove 23, fastening piece is not easy fracture and damages.
Described flange plate 2 is distributed with two contiguous blocks 22 and two connecting grooves 23 away from one end even circumferential of connecting tube 1, and described contiguous block 22 and connecting groove 23 intervals arrange, and mounting hole 21 is arranged between any contiguous block 22 and connecting groove 23.By adopting technique scheme, when two contiguous blocks 22 and connecting groove 23 intervals arrange, not only easy to process, and convenient in the time of design and installation hole 21, in the time of docking two flange, be more prone to, certainly contiguous block 22 and connecting groove 23 can be also three or four etc. accordingly, what mounting hole 21 can be corresponding be arranged in connecting groove 23 and contiguous block 22 on, repeat no more herein.
