Abstract
A magnetron repairing method is disclosed. A method for repairing a nitrogen charging valve used on equipment for producing magnetrons includes a first step of shearing damaged bellows in the valve along a vertical direction of a diameter of the bellows; a second step of grinding two edges of a corrugated sheet; a third step of applying a high vacuum glue to bind two edges of the corrugated sheet, using a fixture to compress the two edges of the corrugated sheet, and enabling the glue to fill full of seams of the corrugated sheet; a fourth step of placing the corrugated sheet in the room temperature for airing, thus to let the corrugated sheet be bound firmly; a fifth step of grinding and finishing the vacuum glue for ensuring evenness of the vacuum glue, thus to let the corrugated sheet stretch out and draw back freely; and a sixth step of setting the repaired valve on a leakage tester for leakage testing, thus to enable the repaired valve to achieve technical requirements for valves.
Description
Technical field
The present invention relates to one
magnetron repairing method.
Background technique
a kind of magnetron repairing method,the method of this reparation valve for filling nitrogen in manufacturing equipment of magnetron.Restorative procedure of the present invention comprises the steps: 1) Vertical direction of the bellows damaged in valve along caliber is cut off; 2) are polished in the both sides of corrugated plate; 3) with high vacuum glue bond both sides corrugated plate, use the both sides of clamp pressing corrugated plate, allow high vacuum glue fully fill up corrugated plate gap; 4) placement is at room temperature dried, and makes it bonding firm; 5) polish, repair unnecessary vacuum glue, guarantee that vacuum glue is smooth, bellows is capable of expansion and contraction; 6) valve of reparation is contained on leak tester hunts leak, make it the technical requirements reaching valve.After nitrogen fill valve door is repaired by method of the present invention.
Summary of the invention
a kind of magnetron repairing method,the method of this reparation valve for filling nitrogen in manufacturing equipment of magnetron.Restorative procedure of the present invention comprises the steps: 1) Vertical direction of the bellows damaged in valve along caliber is cut off; 2) are polished in the both sides of corrugated plate; 3) with high vacuum glue bond both sides corrugated plate, use the both sides of clamp pressing corrugated plate, allow high vacuum glue fully fill up corrugated plate gap; 4) placement is at room temperature dried, and makes it bonding firm; 5) polish, repair unnecessary vacuum glue, guarantee that vacuum glue is smooth, bellows is capable of expansion and contraction; 6) valve of reparation is contained on leak tester hunts leak, make it the technical requirements reaching valve.Nitrogen fill valve door can greatly reduce the consumption of nitrogen, shorten the period of exhaust of high vacuum exhaustion platform after repairing by method of the present invention, and every platform machine does not shorten 5-10 minute not etc.; Alleviate the load of cryopump, improve the degree of vacuum of product, ensure to produce, guarantee product quality, and save expensive spare part expense.The present invention is easy to operate, simple.
