Abstract
The invention relates to a connector made of a titanium alloy memory material. The connector consists of a cylindrical shell which is made of the titanium alloy memory material, a hollow inner hole which is arranged in the cylindrical shell and a middle layer which is arranged between the cylindrical shell and the hollow inner hole and has certain thickness ranging from 1mm to 10mm. The connector is characterized in that the finish of the external surface of the cylindrical shell and the finish of the surface of the inner hole are required to be above inverted-delta 9 to inverted-delta 10, the finish of the surfaces of the upper mouth edge and the lower mouth edge of the cylindrical shell and an inner wall are required to be above inverted-delta 6 to inverted-delta 7, the middle layer is made of a one-way memory material which consists of an alloy memory material of titanium, nickel, copper and the like, the connector is deformed at lower temperature, and after the connector is heated, the connector can be restored to the shape before deformation to enable a casing to be shrunk to tightly connect pipelines. The connector made of the titanium alloy memory material has the advantages that the connector is simple and convenient to produce; the working efficiency is high and the installation speed is fast, the connector can be recycled and the environmental-friendly effect is good; the application scope is wide and the connector is suitable for all kinds of pipelines; the connector is easy to use and maintain; and the sealing performance, the safety and the reliability are high.
Description
One. technical field
The present invention relates to a kind of metal pipe line material interconnection technique and device, particularly relate to a kind of titanium alloy memory material connector.
Two. technical background
Present metal pipe line material interconnection technique mainly is that use screw button is connected and welding method is main interconnection technique with device; But the accident that leakage that causes therefrom and corrosion problems cause is more and more; The back people improve what make great efforts though have an accident; But the not in addition utilization of technical innovation and science on this body structure of material and the characteristic does not also have a kind of titanium alloy memory material connector in the market.
Three. summary of the invention
Content of the present invention provides titanium alloy memory material connector.It can solve present metal pipe line material connection set mainly is with the connection of screw button and welding method and the leakage and the corrosion problems that cause cause unavoidable accident, a difficult problem that reduces and avoid causing casualties because of accident; For the connection metal pipe line of science safety provides effective guarantee.
A kind of titanium alloy memory material connector.It is the cylinder type shell of being processed by the titanium alloy memory material; The hollow endoporus is arranged in the cylinder type shell; Cylinder type shell and hollow endoporus have the mesosphere of certain thickness 1-10mm; The outer surface and the bore area degree of finish that it is characterized in that the cylinder type shell require to reach more than
; The shell of cylinder type and the upper edge of inwall and end opening require to reach more than
along surface finishment; The one way memory material that the material composition in mesosphere is made up of alloy memory materials such as titanium, nickel, copper; Under lower temperature, be out of shape, the shape before the heating back recoverable deformation makes titanium alloy memory material connector ferrule tighten up connection.
Advantage of the present invention is: (1) makes simple, is convenient to produce; (2) high working efficiency, installation rate is fast; (3) reusable edible, environment protection effect is good; (4) with answering scope wide, using applicable to various pipelines should; (5) be easy to operation and maintenance, (6) good airproof performance is safe and reliable.
Four, description of drawings
Accompanying drawing is a structural representation of the present invention
Five, embodiment
A kind of titanium alloy memory material connector.It is the cylinder type shell of being processed by the titanium alloy memory material 1; Hollow endoporus 2 is arranged in the cylinder type shell 1; Cylinder type shell 1 and hollow endoporus 2 have the mesosphere 3 of certain thickness 1-10mm; The outer surface and the bore area degree of finish that it is characterized in that the cylinder type shell require to reach more than
; The shell of cylinder type and the upper edge of inwall and end opening require to reach more than
along surface finishment; Mesosphere 3; The one way memory material formed by alloy memory materials such as titanium, nickel, copper of material composition; Under lower temperature, be out of shape, the shape before the heating back recoverable deformation makes the sleeve pipe contraction that the pipeline two ends are closely connected.
When using titanium alloy memory material connector; The pipeline two end surfaces water dry sanding papers that will connect earlier will polish smooth; Enlarge about 4% titanium alloy memory material connector and be ready to again will be when low temperature entirely in pipe end; The pipeline two ends socket that will connect during assembling adds boiling water less and waters and scald titanium alloy memory material connector its heating is resiled together, forms to engage closely to accomplish to connect.
