Description
Technical field
The invention belongs to glass envelope to cut technical field, and in particular to a kind of envelope side of cutting for gaseous state tritium light source glass tube
Method.
Background technology
Gaseous state tritium light source is a kind of self-excitation weak light source without external energy, with service life is long, light is soft, spoke
The advantages that penetrating low dosage, influence of not climate environment and oil, aqueous medium, there is extensive purposes in many aspects.Gaseous state tritium
The preparation technology of light source, which mainly utilizes, fills tritium system by tritium gas by that can be filled with gaseous state tritium light source glass tube (outside the mouth of pipe after valve pipe
Footpath is generally several millimeters, end closure under glass tube) and then envelope carried out to it cut, wherein envelope cut technique be its critical process it
One, seal the yield rate that the effect cut directly influences gaseous state tritium light source.The envelope of traditional gaseous state tritium light source glass tube cuts technique only
Only it is to be cut using manual single flame envelope, the method depends on the experience and qualification of operating personnel, if the skilled journey of operating personnel
Spend poor, seal the overlong time cut, when gases are heated, they expand and causes glass tube bubbling gas leakage in glass tube, can cause radioactivity tritium
Gas leakage, yield rate are difficult to be guaranteed and obtained gaseous state tritium light source product aesthetic property is poor.Therefore, it is badly in need of at present a kind of
The envelope segmentation method of new gaseous state tritium light source glass tube.
The content of the invention
(1) goal of the invention
According to the problems of prior art, the invention provides a kind of step is simple, envelope is cut into the high gaseous state of power
The envelope segmentation method of tritium light source glass tube.
(2) technical scheme
In order to solve the problems of prior art, the present invention is achieved by the following technical solutions：
A kind of envelope segmentation method for gaseous state tritium light source glass tube, this method are first with filling tritium system by tritium gas through filling tritium
Pipe, can valve pipe enter gaseous state tritium light source glass tube, envelope then is carried out to gaseous state tritium light source glass tube and cut, it is critical that seal the side of cutting
The step of method, includes：
1) can valve pipe lower end weld a hollow tapered glass tube, and in gaseous state tritium light source glass tube and cone-shaped glass
Sealing welding the preceding paragraph transitional glass pipe between pipe, wherein the transitional glass pipe are hollow cylindrical, and its external diameter is less than gaseous state tritium
The external diameter of light source glass tube；
2) take the same position conduct of transitional glass pipe both sides to treat that envelope cuts place, locate one flame gun of each use to it treating that envelope is cut
Envelope is cut after heating；The condition of work for adjusting two flame guns is consistent, and adjusts two flame guns away from accordingly treating that envelope is cut
The position relationship at place keeps identical；
Preferably, described flame gun to transitional glass pipe seal and cut on positioner is installed on, the positioning
Device includes Level tune part and lift adjustment part, treats that envelope cuts the distance at place to adjust the height of flame gun and distance.
Preferably, the external diameter of transitional glass pipe is less than 1mm.
Preferably, in step 1) can valve pipe lower end welding tapered glass tube, it is by the taper glass of 5 sections of heterogeneities
Glass pipe welds together composition using liquefied gas flame welding, the tapered glass tubes of 5 sections of heterogeneities be high-boron-silicon glass,
The mixture of low Pyrex, and according to away from can the order of valve pipe from the close-by examples to those far off, it is high in the cone-shaped glass of 5 sections of heterogeneities
Pyrex, the weight of low Pyrex are 5 than successively:5、6:4、7:3、8:2、9:1.
Preferably, the material of transitional glass pipe and gaseous state tritium light source glass tube is high-boron-silicon glass.
(3) beneficial effect
The application be on the basis of existing envelope cuts technique, for single flame envelope cut during can due to envelope cut position by
It is hot uneven and cause local glass wall penetration gas leakage, the problems such as aesthetic property is poor, cut using double flame guns envelope.Concrete operations are
Transition thin glass tube of the external diameter less than 1mm is welded in the tritium light source glass tube mouth of pipe, double flame guns are made by positioner
The relative position that flame is waited to seal the place of cutting with transition thin glass tube is consistent, and then carrying out envelope to it cuts, and wherein positioner carries
High envelope cuts the convenience and stability of operation, the setting of transition thin glass tube, improves envelope and cuts speed, avoids envelope and cut the time
It is long to cause the generation that gas expands with heat and contract with cold a problem that causing to seal scarfing bubbling in glass tube.
Simultaneously as can valve pipe material for can valve alloy, directly with transitional glass pipe welding can be due to coefficient of expansion phase
Difference is excessive, can not guarantee welding effect.In order to ensure that the envelope of gaseous state tritium light source glass tube cuts effect, applicant is can valve pipe lower end
A tapered glass tube is welded, and the composition of tapered glass tube is different, reduces each section of the coefficient of expansion, realizes cone-shaped glass
Sealing welding between Guan Yuke valves pipe and transitional glass pipe.
