Abstract
The utility model relates to a high-density polyethylene pipeline flange connecting part, which comprises a flange joint and a flange plate. The flange joint is made of high-density polyethylene materials; a stepped structure is arranged on the inner wall of the flange joint; and the inner diameter of connecting ends of the flange joint and a polyethylene pipeline is slightly smaller than the outer diameter of the polyethylene pipeline. The connecting part has the advantages that a high-density polyethylene pipe is in butt joint with the flange joint by adopting hot melting socket, the wall thickness of a joint position is comparatively large, and the connecting part has large butt fusion space and high safety.
Description
Technical field
The utility model relates to a kind of plastic pipe, particularly a kind of high-density polytene pipeline flange connector.
Background technique
The high-density polytene pipeline flange connector adopts the flange connecting head to be connected with pipe hot melting butt joint or electric smelting at present.Adopt the method for hot melt butt joint, the interior external diameter of flanged joint is suitable with external diameter in the pipeline, the wall thickness part is butt-fusion directly, have dislocation slightly and will directly cause joint thickness littler than the actual wall thickness of pipeline, occur leakage accident when line transportation pressure fluid or gas easily, and adopt the electric smelting link cost higher.
The purpose of this utility model is that a kind of safe and reliable high-density polytene pipeline flange connector will be provided.
For achieving the above object, the technical solution of the utility model is: the high-density polytene pipeline flange connector is made up of flange connecting head and flange plate, the flange connecting head is a high-density polyethylene material, inwall is provided with hierarchic structure, and the connecting end internal diameter of flanged joint and polyethylene pipe is slightly less than the polyethylene pipe external diameter.Advantage of the present utility model is that high density polyethylene pipe and flanged joint adopt thermofusible spigot to dock, and the joint wall thickness is thicker, and the welding area is big, and is safe.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model and schematic representation after pipeline is connected;
Specific embodiments
For achieving the above object, the technical solution of the utility model is: as shown in Figure 1, the high-density polytene pipeline flange connector is made up of flanged joint 1 and flange plate 2, flanged joint 1 is a high-density polyethylene material, inwall is provided with hierarchic structure 3, the connecting end internal diameter of flanged joint and polyethylene pipe is slightly less than the polyethylene pipe external diameter, as shown in Figure 2, polyethylene pipe 4 and flanged joint 1 are after the heating plant heating, be in molten state on polyethylene pipe 4 end outer surface and the cross section certain thickness, be in molten state on the internal surface of flanged joint 1 and polyethylene pipe 4 butt ends and the hierarchic structure 3 cross section certain thickness, dock flanged joint 1 this moment with polyethylene pipe 4 thermofusible spigots, because flanged joint 1 is slightly less than polyethylene pipe 4 external diameters with the connecting end internal diameter of polyethylene pipe 4, therefore, the connecting end internal surface of flanged joint 1 and polyethylene pipe 4 and polyethylene pipe 4 outer surface weldings under external force are unusual close and firm, and the cross section of hierarchic structure 3 and polyethylene pipe 4 ends also firmly is welded together simultaneously.Advantage of the present utility model is that high density polyethylene pipe and flanged joint adopt thermofusible spigot to dock, and the joint wall thickness is thicker, and the welding area is big, and is safe.
