Of the present utility modelly further be set to: described the first projection is provided with projection with respect to the other end of positive flange, and described the second groove is provided with the draw-in groove suitable with projection, described the first projection is conflicted and is connected with the second groove.
By adopting technique scheme, on the end face of the first projection, be also provided with projection, the shape of projection is preferably tri-prism projection, on the second groove, be provided with the draw-in groove suitable with projection simultaneously, both realize clamping when mounted, have strengthened sealing between positive flange and secondary flange, make the pipeline circulation on flange more stable, between the second projection and the first groove, also can be provided with equally projection and draw-in groove, greatly enhanced leaktightness performance simultaneously.
Of the present utility modelly further be set to: on described positive flange, be also provided with through hole step trough is coaxially set, on described secondary flange, be also provided with the annular protrusion suitable with step trough.
By adopting technique scheme, on positive flange, be provided with step trough, step trough position can be positioned on through hole outward edge, step trough can with through hole intercommunication, on secondary flange, be provided with the annular protrusion suitable with step trough simultaneously, annular protrusion is also preferably placed at through hole outer edge, make in the time that docking is installed, annular protrusion and step trough can well carry out clamping, while reducing through hole pipe laying, gap between positive flange and secondary flange becomes better, has improved sealing.
Of the present utility modelly further be set to: described annular protrusion outer surface is provided with raised line, and described step trough is provided with the connecting groove suitable with raised line.
By adopting technique scheme, also be provided with many raised lines at annular protrusion outer surface, step trough and annular protrusion are suitable simultaneously, make to be provided with equally on step trough the connecting groove suitable with raised line, what make when mounted can annular protrusion to contact with step trough is tightr, has strengthened the sealing between positive flange and secondary flange.
Of the present utility modelly further be set to: on described step trough, be also provided with rubber ring.
By adopting technique scheme, on step trough, be also provided with the rubber ring suitable with step trough size shape, because rubber ring has certain ductility, there is certain elasticity simultaneously, can there is deformation, annular protrusion can better be contacted with rubber ring.
The utlity model has following advantage: the first projection on positive flange and the second groove respectively with the second groove and the second projection clamping of secondary flange, annular protrusion and step trough clamping, just the good airproof performance between flange and secondary flange, is difficult for causing leakage.
