Above-mentioned a kind of alloy flange, is characterized in that: uniformly on described flange disk body offer bolt hole.
Above-mentioned a kind of alloy flange, is characterized in that: described Pipe installing hole is provided with extension tube, and flange disk body and extension tube are welded to connect.
Above-mentioned a kind of alloy flange, is characterized in that: described flange disk body offers with the joint of extension tube and welds groove.
Above-mentioned a kind of alloy flange, is characterized in that: described alloy-layer is 12Cr1MoV alloy-layer.
The utility model compared with prior art has the following advantages:
1, the utility model structure is simple, reasonable in design.
2, the utility model arranges the self-locking block that can stretch under the action of the spring, on pipeline, offer corresponding self-locking grooves simultaneously, make after flange disk body and pipeline are tentatively installed, self-locking after self-locking block press-in self-locking grooves, not only serve the effect of location, self-locking that can also be good, flange plate can not produce and rock in subsequent installation operation.
3, the utility model arranges extension tube, and extension tube outside can be set with large aperture pipeline, and extension tube inside can be set with small aperture pipeline.
4, the utility model to offer with the joint of extension tube at flange disk body and welds groove, and ensure the bonding area of pipeline and flange more greatly by welding groove, it is more firm to weld, and reliability is high.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
