Face paste closes the identical curved surface connecting pin of end curvature, and one end of flange two is the curved surface installation end being bonded with curved surface connecting pin, flange
One is detachably connected with flange two, and the other end of flange two is equipped with shield sealing device.
The other end of the flange two is curved surface welding ends identical with curved surface installation end curvature.
The other end of the flange two is the axially vertical smooth welding ends with flange two.
The shield sealing device is cylinder, and barrel soldering is on flange two.
The flange one is welded on the steel loop of tunnel duct piece inner wall, and flange one and flange two are equipped with several phase interworkings
The bolt hole of conjunction, flange one are connected through a screw thread part and are detachably connected with flange two.
The application of a surface end of the flange one is equipped with welding planar end surface for welding, and flange two is equipped with for screw thread
The connection planar end surface of connector fitting.
The utility model has the beneficial effects that the curved surface connecting flange without cut off connecting flange can meet equipment passage want
It asks, solves the problems, such as that portal welded flange needs repeatedly cutting, provide active and effective solution party for practice of construction
Case substantially increases construction efficiency, effectively reduces enterprise's production cost.
