Description
Technical field
The invention belongs to a kind of quartz ampoules to manufacture ancillary equipment, specifically, more particularly to a kind of quartz continuous melting furnace core bar
Stable gas pressure device.
Background technology
Existing fused quartz melt trombone slide technology is that quartz ampoule is directly pulled out from fire door, and is cut to quartz ampoule in lower section
It cuts, during cutting, pipe range is continuously increased, and pressure gradually changes, and is especially cut pipe cut-out and is caused gas band inside and outside pipe
The violent draught head variation come, can cause to impact to the forming process of production of quartz tubes key, be controlled in high precision tube wall
Under, it causes quartzy pipe outside diameter, the stage up and down of wall thickness equal-specification to have notable difference, the quality control of product is brought very big
Influence.Minimum gas is passed in production process to core bar to stablize air pressure, unstable is that long intraductal atmospheric pressure is big, works as cut-out
After one section, rostrum so shortens, and air pressure becomes smaller suddenly, and air demand does not catch up with the variation of pipe internal volume, and the suddenly change of air pressure can make
The root (i.e. the junction of prepattern and sizing) of pipe is thick or thin regular variation, if Pipe Cutting length stabilisation, frequency are steady
It is fixed, regular variation will be coarse and fine on the pipe cut, in spite of plant equipment it is more superior, control means one
Point, precision is high not to be sexually revised a little at all, and up to the present this problem is in the industry cycle or global problem.
Invention content
It is an object of the present invention to provide a kind of quartz continuous melting furnace core bar stable gas pressure devices, to overcome quartz drawing in the prior art
The core bar air pressure unstable defect for be easy to causeing the fluctuation of tubing size heterogeneity when being cut to quartz ampoule in pipe production process.
Realization that the present invention adopts the following technical solutions：
A kind of quartz continuous melting furnace core bar stable gas pressure device, including gas pressure detection instrument, control magnet valve, gas flow
Meter, pressure maintaining valve, internal iron device, magnetic device, the gas pressure detection instrument is located at quartzy stove for drawing tube fire door, for detecting
The gas pressure of quartzy stove for drawing tube fire door, the control magnet valve is connect with gas pressure detection instrument, according to gas pressure detection
The flow of the pressure signal control input gas of instrument, the iron device in inside are respectively provided at the inside of quartzy tube wall with magnetic device
And outside, and synchronization action, the magnetic device are connect with gas pressure detection instrument, according to the pressure of gas pressure detection instrument
Signal controls floating up and down for itself, and the control magnet valve, gas flowmeter and pressure maintaining valve are connected on appendix.
The iron device in inside includes Circular Plate, and the Circular Plate bosom is equipped with one layer of former, internal iron dress
Global sections are set in I-shaped.
The Circular Plate upper and lower ends are respectively equipped with protection ring.
The protection ring remains less than the gap of 0.9mm with quartzy tube wall.
The protection ring is graphite annulus.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention plays quartzy trombone slide pipe internal core rod air pressure fluctuation
Effective control has been arrived, a stable air pressure is kept in pipe, tubing specification caused by greatly reducing intraductal atmospheric pressure fluctuation is poor
Different fluctuation greatly reduces cost waste, improves product qualification rate, there is extraordinary product quality to promote effect.

Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of quartz continuous melting furnace core bar stable gas pressure device, including gas pressure detection instrument 1, control magnet valve
2, gas flowmeter 3, pressure maintaining valve 4, internal iron device 5, magnetic device 8, the gas pressure detection instrument 1 are located at quartzy stove for drawing tube
At fire door 10, the gas pressure for detecting quartzy stove for drawing tube fire door 10, the control magnet valve 2 connects with gas pressure detection instrument 1
It connects, the flow of input gas is controlled according to the pressure signal of gas pressure detection instrument 1, the iron device 5 in inside is filled with magnetic
It sets 8 and is respectively provided at the inside and outside of quartzy tube wall 6, and synchronization action, the magnetic device 8 connects with gas pressure detection instrument 1
It connects, floating up and down for itself, the control magnet valve 2, gas flowmeter is controlled according to the pressure signal of gas pressure detection instrument 1
3 and pressure maintaining valve 4 be connected on appendix, quartzy stove for drawing tube fire door 10 is continuously in appendix and inputs gas, and in quartz ampoule
Form stabilizing gas 9.
As shown in Fig. 2, internal iron device 5 is located inside quartzy tube wall 6, internal iron device 5 includes Circular Plate 12, circle
12 bosom of ring is equipped with one layer of former 11, and internal iron 5 global sections of device are in I-shaped.The upper and lower end of Circular Plate 12
Each band one encloses protection ring 7, and protection ring 7 is kept with quartzy tube wall 6 at a distance within grade about 0.9mm, to prevent from scratching inner tube
Wall, wherein protection ring 7 preferably uses the good graphite annulus of anti-scratch effect.
