Abstract
The invention relates to a wolfram rod and quartz direct sealing-type super high pressure capillary mercury lamp in the field of electron vacuum. It can effectively avert the lamp frying and gas leakage. It changes the traditional transition attended mode which adds molybdenum and platinum between the electrode and the lead wire.
Description
Technical field
The present invention relates to the electronic vacuum technical field.
Background technology
Ultra-high voltage capillary mercury lamp commonly used, sealing-in between its electrode and the quartz ampoule, be to adopt the sealing-in of molybdenum platinum transient mode, be that sealing surface is that molybdenum platinum is with quartzy, its tungsten electrode is connected with molybdenum platinum, molybdenum platinum is connected with molybdenum rod lead-in wire again, and this cumbersome connected mode, manufacturing process complexity, qualification rate is low, cost is higher, is difficult to the working condition under the adaptation superhigh pressure.
Summary of the invention
Purpose of the present invention just provides a kind of simple in structure, reliable in quality, long-life capillary quartz burner, and it can prevent effectively that fluorescent tube from bursting and leak gas.
In order to achieve the above object, technical scheme of the present invention is to have changed the transition connected mode that adds molybdenum platinum between traditional electrode and the lead-in wire, and the form of employing electrode, lead-in wire, the integrated tungsten bar of sealing surface, generally speaking, can not directly carry out vacuum seal between tungsten bar and the quartz ampoule, can cause quartz ampoule to burst like that or sealing surface gas leakage.In order to overcome the directly contradiction of sealing-in of quartz ampoule and tungsten bar, we have adopted the method that adds transition zone between quartz ampoule and tungsten bar, promptly make a kind of macromolecule sealing surface that is referred to as on tungsten bar surface, this sealing surface is under the fusing of oxyhydrogen flame, form a kind of likeness in form quartz glass pearl, the tungsten electrode that puts this quartz glass pearl can be organically and the quartz ampoule sealing-in.
Adopt this mode that adds transition zone, have many good qualities, one has been avoided cumbersome connection the between tungsten electrode and molybdenum platinum, the molybdenum lead-in wire, make simple to operately, its two sealing surface can not burst or leak gas, and it is three because conductive cross-sectional area has increased, so high pressure resistant impact property has been strengthened, it four is to have increased mechanical strength, and anti-poly-cold heat build-up performance has improved, effectively the useful life of prolonging lamp tube.It five is to have saved transition to connect some used precious metal materials, as tantalum piece, molybdenum platinum, molybdenum rod etc., cost has been reduced.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
1 transformer, 2 tungsten electrodes, 3 quartz glass pearls, 4 quartz capillaries among the figure.
Embodiment
Quartz glass pearl 3 is made like this, quartz sand, borax, tungsten powder, sodium oxide molybdena, aluminium oxide, calcium oxide, barium monoxide etc. is mixed stir, and forms through the oxyhydrogen flame high-temperature melting after the grinding.Tungsten electrode 2 fuses together in oxyhydrogen flame high temperature with quartz capillary 4.The quartz burner that sealing-in is good will insert in the vacuum system by technological requirement, carries out exhaust, electrode brightnessization, fills mercury etc.After exhaust is qualified, from vacuum system, separate.Seal blast pipe at last, quartz capillary has just been made like this, and the capillary that makes will insert burn-in test in 4500 volts of transformers 1.
Claims (3)
1. tungsten bar and quartz direct sealed type ultra-high voltage capillary mercury lamp is characterized in that the lead-in wire of capillary mercury lamp, sealing-in place and tungsten electrode form a kind of one tungsten bar structure, and one tungsten bar scribbles the transition zone that special material forms with thereafter quartzy sealing-in place.
2. tungsten bar according to claim 1 and quartz direct sealed type ultra-high voltage capillary mercury lamp is characterized in that, described transition zone forms a kind of crystalline solid---quartz glass pearl behind the oxyhydrogen flame high-temperature melting.
