the symbols in the figure illustrate: 1. a sleeve head is converted; 2. an inner wall of the port; 3. an inner diameter through hole; 4. a finite block; 5. a straight pipe body; 6. the end part of the sleeve head.
Detailed Description
In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.
As shown in figure 1, the alloy pipeline of the utility model comprises a conversion sleeve head 1 and a straight pipe body 5, wherein the conversion sleeve head 1 comprises a port inner wall 2, a sleeve head end part 6 and an inner diameter through hole 3. Wherein the straight pipe body (5) is internally provided with a limiting block structure.
Bosses are arranged at the upper end and the lower end of the sleeve head end part 6, so that the pipe joint can be fixed conveniently during diameter expansion. The end part 6 of the sleeve head can be designed into a bell mouth with 1:10 taper, so that the contact stress of the conversion sleeve head 1 and a connected pipe is gradually reduced, and the connected pipe is avoidedStress concentration is prevented from forming at the sleeve head end part 6 of the conversion sleeve head 1, and the anti-fatigue capability of the conversion sleeve head 1 is improved. The inner wall 2 of the port of the conversion sleeve head 1 is plated with a layer of Al-Mn alloy, and the contact area of the conversion sleeve head 1 and a pipeline is increased and the interface sealing performance is improved due to good plasticity of the Al-Mn alloy; in addition, the contact surface of the pipeline and the Al-Mn alloy is flat, so that the pipeline joint can be disassembled and reused. The conversion sleeve head 1 can be stored at normal temperature due to the adoption of Ni47Ti44Nb9The wide lag metal makes the transportation and storage of the conversion sleeve head 1 extremely convenient, and accords with the daily life of people. Inside being equipped with of internal diameter through-hole 3 has limiting block 4, can restrict the pipeline position, avoids the pipeline to appear colliding or connect infirm.
The material of the conversion sleeve head 1 and the straight pipe body 5 adopts Ni47Ti44Nb9The alloy has larger phase change lag, and has excellent shape memory effect and superelasticity, so that the port sealing performance is better, and the alloy can bear larger pressure.
The alloy pipeline interface inner diameter through hole 3 is large enough, and is provided with a limiting block 4 to prevent the pipeline from sliding after installation. The outer surfaces of the conversion sleeve head 1 and the straight tube body 5 are coated with a layer of quasicrystal film with better corrosion resistance, so that the leakage at the position of the inner wall 2 of the port caused by underwater corrosion is prevented. In addition, the compressive strength of the pipeline contacted with the Ni-Ti-Nb alloy interface is enough, the conversion sleeve head 1 can shrink inwards during installation to generate larger stress, the inner wall 2 of the pipeline port is plated with Al-Mn alloy and deforms under the action of larger stress, the stress of the joint to the pipeline is reduced, and the alloy joint is heated as long as the outer diameter of the pipeline is smaller than the inner diameter of the alloy joint, and the Ni-Ti-Nb alloy interface is heated as the outer diameter of the pipeline is smaller than the inner diameter of the alloy joint47Ti44Nb9The alloy is subjected to phase change and inward contraction, so that the alloy can be adjusted according to different outer diameters of pipelines and can be widely used.
After the installation, the inner wall 2 of the port is connected with the pipeline, and phase change occurs during heating and installation, so that the port is tightly connected with the pipeline. When liquid flows through the inner diameter through hole 3, the inner wall 2 of the port and the sleeve head end 6 are not easy to be damaged under the action of high pressure because the material has super elasticity and shape memory property. After the installation is finished,if the alloy interface needs to be removed, Ni only needs to be cooled at low temperature47Ti44Nb9The phase change is carried out again, and the alloy joint can be used for multiple times.
It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are intended to be covered by the present invention.
