For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of alloy flange, it is characterized in that: include flange disk body, described flange disk body is provided centrally with Pipe installing hole, it is characterized in that: uniform on described flange disk body offer three through holes, described through hole is extended to Pipe installing hole by the outer circumferential edges of flange disk body, it is disposed with self-locking nut from the outer circumferential edges of flange disk body to the direction in Pipe installing hole in described through hole, upper block, self-locking spring, lower block and self-locking block, the two ends of described self-locking spring are connected with upper block and lower block respectively, described self-locking block is fixedly installed on the lower section of lower block, described self-locking block is vertebral body shape, in described Pipe installing hole, pipeline is set, on the outer wall of described pipeline and the position corresponding with described self-locking block is provided with the self-locking grooves for self-locking block embeds pipeline outer wall, described flange disk body is three-decker, including the first wearing layer, the second wearing layer, and the alloy-layer between the first wearing layer and the second wearing layer.
Above-mentioned a kind of alloy flange, it is characterised in that: uniform on described flange disk body offer bolt hole.
Above-mentioned a kind of alloy flange, it is characterised in that: being provided with extension on described Pipe installing hole, flange disk body and extension are welded to connect.
Above-mentioned a kind of alloy flange, it is characterised in that: described flange disk body offers with the junction of extension and welds groove.
Above-mentioned a kind of alloy flange, it is characterised in that: described alloy-layer is 12Cr1MoV alloy-layer.
The present invention compared with prior art has the advantage that
1, present configuration is simple, reasonable in design.
2, the present invention arranges the self-locking block that can stretch under the action of the spring, on pipeline, offer the self-locking grooves of correspondence simultaneously, make after flange disk body and pipeline are tentatively installed, self-locking after self-locking block press-in self-locking grooves, not only act as the effect of location, self-locking that can also be good, ring flange will not produce to rock in subsequent installation operation.
3, the present invention arranges extension, can be set with large aperture pipeline outside extension, can be set with small-bore pipeline inside extension.
4, the present invention offers with the junction of extension at flange disk body and welds groove, ensures that pipeline is bigger with the bonding area of flange by welding groove, and it is more firm weld, reliability height.
Below by drawings and Examples, technical scheme is described in further detail.
