球式水温表的铜导管断裂后,乙醚流失,水温表失效。要修复它,只有将铜管焊接好,重新向感温球内灌注乙醚,并切实封住。然而乙醚是一种沸点很低,极易蒸发的液体。当乙醚灌到感温球内后,直接用焊锡焊封注入口时,烙铁与注入口一接触,乙醚就受热,变成一股强烈的气流将熔化了的焊锡吹开,大部分从管口跑掉,很难将其封在管内,不能达到要求。 Ball water temperature gauge copper catheter rupture, the loss of ether, water temperature table failure. To fix it, only the brass is welded and the ether is re-infused into the temperature-sensitive bulb and sealed. However, ether is a very low boiling, highly volatile liquid. When the ether is filled into the temperature-sensitive ball, the soldering iron is directly injected into the soldering port. When the soldering iron touches the injecting port, the ether is heated and becomes an intense air stream, which blows away the melted soldering solder, Run away, it is difficult to seal it in the tube, can not meet the requirements.
