Description
Technical field
This utility model belongs to a kind of quartz ampoule and manufactures auxiliary equipment, specifically, particularly relates 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 directly pulls out from fire door, and cuts quartz ampoule in lower section
Cutting, during cutting, pipe range is continuously increased, and pressure gradually changes, and particularly cutting pipe cuts off and causes the inside and outside gas band of pipe
The violent draught head change come, can impact the forming process that production of quartz tubes is crucial, controls at made with high precision tube wall
Under, cause quartz ampoule external diameter, the stage up and down of wall thickness equal-specification has notable difference, brings the biggest to the quality control of product
Impact.To pass to minimum gas with stable air pressure to core bar in production process, unstable is that long intraductal atmospheric pressure is big, works as cut-out
After one joint, rostrum so shortens, and air pressure diminishes suddenly, and air demand does not catches up with the change of pipe internal volume, and the unexpected change of air pressure can make
Root (i.e. prepattern and the junction of sizing) the thick or thin regular change of pipe, if Pipe Cutting length stabilisation, frequency is steady
Fixed, will slightly have thin regular change at the Guan Shangyou cut, despite plant equipment more superior, control device one
Point, precision is high does not a little have essence to change, up to the present this problem in the industry cycle still global problem.
Utility model content
This utility model purpose is to provide a kind of quartz continuous melting furnace core bar stable gas pressure device, to overcome stone in prior art
When in English trombone slide production process cutting quartz ampoule, core bar air pressure instability easily causes the defect of tubing size heterogeneity fluctuation.
This utility model realizes by the following technical solutions:
A kind of quartz continuous melting furnace core bar stable gas pressure device, including gas pressure detection instrument, controls magnet valve, gas flow
Meter, pressure maintaining valve, internal iron device, magnetic device, described gas pressure detection instrument is located at quartz stove for drawing tube fire door, is used for detecting
The gas pressure of quartz stove for drawing tube fire door, described control magnet valve is connected with gas pressure detection instrument, and it is according to gas pressure detection
The pressure signal of instrument controls the flow of input gas, and the iron device in described inside and magnetic device are respectively provided at the inside of quartz tube wall
And outside, and synchronization action, described magnetic device is connected with gas pressure detection instrument, and it is according to the pressure of gas pressure detection instrument
Signal controls fluctuating of self, and described control magnet valve, gas flowmeter and pressure maintaining valve are connected on appendix.
The iron device in described inside includes that Circular Plate, described Circular Plate bosom are provided with one layer of former, internal iron dress
Put global sections in I shape.
Described Circular Plate is respectively arranged at two ends with protection ring up and down.
