Description
Technical field
The invention belongs to a kind of quartz ampoule and manufacture auxiliary equipment, specifically, particularly relate to a kind of quartz continuous melting furnace core bar air pressure steady
Determine 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, is cutting
During cutting, pipe range is continuously increased, and pressure gradually changes, and particularly cutting pipe cuts off cause the inside and outside gas of pipe to bring violent
Draught head changes, and can impact the forming process that production of quartz tubes is crucial, under made with high precision tube wall controls, causes stone
English pipe external diameter, the stage up and down of wall thickness equal-specification have notable difference, and the quality control of product is brought the biggest impact.Raw
To pass to minimum gas with stable air pressure to core bar during product, unstable is that long intraductal atmospheric pressure is big, after cutting off a joint, and pipe
Suddenly shortening, 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 the root of pipe (i.e.
Prepattern and the junction of sizing) thick or thin regular change, if Pipe Cutting length stabilisation, frequency stable, will cut
Under Guan Shangyou slightly have thin regular change, despite plant equipment more superior, control device is better, and precision is high by one
Point, does not has essence to change, up to the present this problem in the industry cycle still global problem.
