The utility model is further set to: the height of the relative connecting tube outer wall of described apex sealing strip is suitable with the height of the first relative connecting tube outer wall in convex edge.
By adopting technique scheme, the height of the relative connecting tube outer wall of apex sealing strip is consistent with the height of the first relative connecting tube outer wall in convex edge, also just consistent with the height of the second relative connecting tube outer wall 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 a plurality of, 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 when design and installation hole, when docking two flange, be more prone to.
