Abstract
The invention relates to a manufacture method of a superconducting tube, comprising the following steps: an interface plug is fixed at an opening of a silica tube, and has a certain distance from the opening and good welding; the silica tube is vacuumized by a metal tube of the interface plug and then injected with superconducting medium and the metal tube is sealed; and a silica sealing plug is added at the opening and welded well with the silica tube. One or a plurality of bosses is/are arranged at the outer edge of the interface plug. The manufacture method is simple and easy to understand, the product has high quality, the service life is long, the degree of temperature resistance can reach 1500 DEG C and the efficiency of heat conduction reaches more than 90 percent.
Description
Technical field
The present invention relates to a kind of preparation method of sealed tube.
Background technology
The manufacturing process of superconducting pipe generally comprises and vacuumizes, fills superconductive medium and seals three steps, and its difficult point is the making of interface.Existing superconducting pipe is generally all made with metal tube, but the superconducting pipe made from metal can not use under corrosive environment.Quartz with corrosion resistance is done superconducting pipe, and it has difficulties the aspect such as sealing, vacuumize.
Summary of the invention
The object of the present invention is to provide a kind of good sealing effect, the preparation method of simple and practical superconducting pipe.The present invention specifically may further comprise the steps:
The interface plug is fixed on the opening part of quartz ampoule, and the interface plug has certain distance apart from opening part, determines as required that apart from size purpose is conveniently to vacuumize and seal, and welds; By interface metal tube beyond the Great Wall, earlier quartz ampoule is evacuated, and then the superconductive medium of annotating inside, closed metal pipe again; Add a quartzy sealing-plug at opening part, weld, guarantee the sealing effectiveness of quartz ampoule with quartz ampoule.
The present invention is owing to adopt dual sealing tech, and first road is the interface of a band metal tube, and second road is that quartz seals, and the first road sealing tech has guaranteed to vacuumize, fill the convenience of operations such as superconductive medium, and the second road sealing tech has guaranteed the quality of sealing.After tested, of the present inventionly high temperature resistantly reach 1500 degrees centigrade, heat transfer efficiency reaches more than 90%.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done more into detailed description.
Embodiment
As shown in Figure 1, the opening part that the making of quartz superconducting tube earlier is fixed on interface plug 3 quartz ampoule 4 is a point inward, also has certain distance apart from opening part simultaneously, conveniently to vacuumize and to seal, welds; By interface metal tube 2 beyond the Great Wall, earlier quartz ampoule is evacuated, and then the superconductive medium of annotating inside, again with metal tube 2 sealings; Add a circle or square quartzy sealing-plug 5 at opening part, weld, guarantee the sealing effectiveness of quartz ampoule with quartz ampoule.The present invention has adopted the interface plug of band metal tube, dual-seal, the service life of having improved quartz superconducting tube.After tested, quartz superconducting tube is high temperature resistant to reach 1500 degrees centigrade, and heat transfer efficiency reaches more than 90%.
The quartz ampoule of invention can be multiple shape, and as among Fig. 3 being circular quartz ampoule, Fig. 4 is square quartz ampoule, and Fig. 5 is the spherical quartz pipe.
