Description
Technical field
The utility model relates to high voltage switchgear manufacturing technology field, be specifically related to a kind of can directly and the Novel sealing T-Ring of crunch seal.
Background technology
In vacuum interrupter, travelling wave tube speed, adjust in the electron tube productions such as pipe, need the technique of a large amount of employing ceramic and metal jointing and corresponding parts, the main material of usual ceramic and metal jointing determines expansion sealing-in teleoseal (be commonly called as and can cut down) with ceramic expansion coefficient similar, as trade mark 4J33,4J34 can cut down.Sealing ring part after processing not only will electroplate one deck nickel, also in hydrogen furnace, will could carry out soldering sealing-in after high-temperature process with pottery etc., and teleoseal is expensive.
Although stainless steel sealed ring is used widely in vacuum interrupter is produced in recent years, between pottery and stainless steel sealed ring, all add the oxygen-free copper transition part of a thickness 0.5 ~ 2mm, to reduce stress of sealing.So not only increase an oxygen-free copper part, also need multiplex a slice silver-copper brazing alloy, add a sealing weld more, have impact on rate of finished products.
Utility model content
The utility model object be to provide a kind of can directly and the Novel sealing T-Ring of crunch seal, to solve many defects that prior art deficiency causes.
A kind of can directly and the Novel sealing T-Ring of crunch seal, described sealing ring comprises the soldering edge of a knife and solder layer, the described soldering edge of a knife is located at ceramic cartridge side, described solder layer is located between the soldering edge of a knife and ceramic cartridge, described sealing ring material is 316L cold-rolling stainless steel sheet material, and the described soldering edge of a knife is featheredge structure, and soldering knife edge thickness is 0.1mm ~ 1mm, knife edge length 3mm ~ 10mm, described solder layer material is silver-bearing copper nickel solder.
Preferably, described sealing ring is cylinder-like structure, is protruding with shoulder laterally bottom sealing ring.
Preferably, be connected with by hypotenuse the first circular platform caved inward bottom described sealing ring.
Preferably, step-like projection is provided with bottom described sealing ring.
Preferably, be connected with by arc-shaped edges the second circular platform caved inward bottom described sealing ring.
The utility model has the advantage of, this kind of sealing ring employing 316L stainless steel cold-rolled plate carrys out alternative teleoseal materials processing and becomes sealing ring, directly weld with ceramic cartridge, do not need transition part, reduce stress of sealing, adopt featheredge transition, length rationally with ceramic cartridge soldering sealing-in position, there is good plastic deformation, and greatly reduce stress of sealing, improve tensile strength and air-tightness; Adopt special solder, stainless steel does not need to carry out electroplating processes and can directly weld with ceramic cartridge, cancels part electroplating technology, reduces the pollution to environment; Adopt special cleaning and electrolytic polishing process, greatly improve the surface cleanliness quality of part, do not need to do surface treatment again after one-step seal-exhaust and just meet instructions for use; Stainless price is well below teleoseal, and cost reduces greatly.
