Abstract

The invention discloses a high-performance gap elbow. The high-performance gap elbow comprises a first joint and a second joint; the first joint and the second joint are connected through a bending pipe; the bending pipe is a multilayer structure consisting of a titanium pipe, a copper pipe and a carbon steel pipe in sequence from inside to outside; the titanium pipe, the copper pipe and the carbon steel pipe are fused with each other; the pipe wall of the copper pipe is a composite casting structure; multiple stainless steel ribs are arranged in the pipe wall of the copper pipe in the radial direction of the pipe body; the stainless steel ribs are distributed by center symmetry with the center shaft of the copper pipe as center; and the ratio of the diameters of the stainless steel ribs to the thickness of the copper pipe is 1: 2. The high-performance gap elbow is mainly formed by fusing three layers of pipes, wherein the copper pipe in middle is not a homogeneous metal pipe; multiple stainless steel ribs are fused in the pipe wall of the copper pipe through a composite casting mode; the stainless steel ribs greatly improve the mechanical performance and the toughness of the whole elbow bending part; and even if a larger angle is bent, the breakage is not easy to generate.

Example Embodiment

[0012] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention will be defined more clearly.
[0013] Such as figure 1 , figure 2 As shown, a high-performance seam elbow 1 includes a first interface 10 and a second interface 20. The first interface 10 and the second interface 20 are connected by a bending tube 30, the bending tube 30 is a multi-layer structure. From the inside to the outside, there are titanium pipe 31, copper pipe 34 and carbon steel pipe 32 in order. The titanium pipe 31, copper pipe 34 and carbon steel pipe 32 are welded to each other. The wall of the copper pipe 34 is a composite casting structure. The wall of the copper tube 34 is provided with a plurality of stainless steel ribs 33 along the radial direction of the tube body. The stainless steel ribs 33 are distributed symmetrically around the central axis of the copper tube 34. The ratio of the diameter of the stainless steel rib 33 to the thickness of the copper tube 34 is 1:2.
[0014] As a further improvement to the present invention, the thickness ratio of the titanium tube 31, the copper tube 34 and the carbon steel tube 32 is 1:5:2.
[0015] As a further improvement to the present invention, the angle between the first interface 10 and the second interface 20 is 45-90 degrees.
[0016] The high-performance seam elbow of the invention is mainly formed by welding three layers of pipes. The copper pipe in the middle is not a homogeneous metal pipe. The copper pipe wall is melted with multiple stainless steels by compound casting. Ribs, these stainless steel ribs greatly improve the mechanical properties and toughness of the entire elbow bending part, and it is not easy to break even if it is bent at a large angle.
[0017] The above is only one embodiment to illustrate the design idea of ​​the present invention. If the system allows, the present invention can be extended to connect more functional modules at the same time, thereby maximizing its function.
[0018] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through creative work shall be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
