Description
Technical field
The invention belongs to glass envelope and cut technical field, be specifically related to a kind of envelope segmentation method for gaseous state tritium light source Glass tubing.
Background technology
Gaseous state tritium light source is a kind of self-excitation weak light source without the need to external energy, has long service life, light is soft, radiation dose is low, the advantage such as impact of not climate environment and oil, water medium, has purposes widely in many aspects.The preparation technology of gaseous state tritium light source mainly utilizes and fills tritium system (mouth of pipe external diameter is for being generally several millimeter by being filled with gaseous state tritium light source Glass tubing after valve pipe by tritium gas, end closure under Glass tubing) then envelope is carried out to it and cut, wherein envelope cuts technique is one of its critical process, seals the yield rate that the effect of cutting directly has influence on gaseous state tritium light source.It is only adopt manual single flame envelope to cut that the envelope of traditional gaseous state tritium light source Glass tubing cuts technique, this method depends on experience and the skill level of operator, if operator's skill level is poor, seal the overlong time of cutting, in Glass tubing, when gases are heated, they expand and cause Glass tubing bubbling to leak gas, and the gaseous state tritium light source product aesthetic property that radioactivity tritium gas leaks, yield rate is difficult to be guaranteed and obtain can be caused poor.Therefore, a kind of envelope segmentation method of new gaseous state tritium light source Glass tubing is badly in need of at present.
Summary of the invention
(1) goal of the invention
Problem existing for prior art, the invention provides the envelope segmentation method that a kind of step is simple, envelope is slit into the high gaseous state tritium light source Glass tubing of power.
(2) technical scheme
In order to solve the problem existing for 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 tubing, the method first utilizes to fill tritium system by tritium gas through filling tritium pipe, can entering gaseous state tritium light source Glass tubing by valve pipe, then carry out envelope to gaseous state tritium light source Glass tubing to cut, key is, the step of envelope segmentation method comprises:
1) tapered glass tube of a hollow can welded in valve pipe lower end, and between gaseous state tritium light source Glass tubing and tapered glass tube seal welding the preceding paragraph transitional glass pipe, wherein this transitional glass pipe is hollow cylindrical, and its external diameter is less than the external diameter of gaseous state tritium light source Glass tubing;
2) getting transitional glass pipe both sides same position as treating that envelope cuts place, sealing after it being heated until each employing in the envelope place of cutting flame gun and cutting; The working conditions adjusting these two flame gun is consistent, and adjust these two flame gun apart from corresponding wait to seal cut place position relationship keep identical;
Preferably, described flame gun is cut being installed on locating device seals transitional glass pipe, and this locating device comprises horizontal adjustment parts and lift adjustment parts, waits to seal the distance of cutting place with the height and distance that regulate flame gun.
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 utilized liquefied gas flame welding to weld together to form by the tapered glass tube of 5 sections of heterogeneities, the tapered glass tube of these 5 sections of heterogeneities is all mixtures of high-boron-silicon glass, low borosilicate glass, and according to apart from can valve pipe order from the close-by examples to those far off, in the cone-shaped glass of these 5 sections of heterogeneities, the weight percentage of high-boron-silicon glass, low borosilicate glass be 5:5,6:4,7:3,8:2,9:1 successively.
Preferably, the material of transitional glass pipe and gaseous state tritium light source Glass tubing is high-boron-silicon glass.
(3) beneficial effect
The application cuts on the basis of technique in existing envelope, can cut position and to be heated inequality and the problem such as cause the gas leakage of the glass wall penetration of local, aesthetic property poor, adopting two flame gun envelope to cut for cutting in process in single flame envelope due to envelope.Concrete operations weld at the tritium light source Glass tubing mouth of pipe transition thin glass tube that an external diameter is less than 1mm, the flame of two flame gun and transition thin glass tube is made to wait that the relative position sealing the place of cutting is consistent by locating device, then carry out envelope to it to cut, wherein locating device improves convenience and the stability that envelope cuts operation, the setting of transition thin glass tube, improve envelope and cut speed, avoid envelope and cut the generation that overlong time causes gas in Glass tubing to expand with heat and contract with cold causing the unfavorable conditions such as envelope scarfing bubbling.
Meanwhile, owing to can the material of valve pipe be can valve alloy, directly weld with transitional glass pipe and understand because the coefficient of expansion have big difference, do not ensure welding effect.In order to ensure that the envelope of gaseous state tritium light source Glass tubing cuts effect, applicant can weld a tapered glass tube in valve pipe lower end, and the composition of tapered glass tube is different, reduces the coefficient of expansion of each section, achieve tapered glass tube and can seal welding between valve pipe and transitional glass pipe.
