| Abstract: | The special sniffing probe and spray probe for leak testing of flange were designed and made.The inside-out testing and hood testing,two overall leak detection methods,were made research on and established.In these methods,the cavity which was ringed by multi-layer tight structures in the flange was used as the vacuum cave in leak detecting.By these means,the sensitivity and reliability of the leak detection for the flange were further improved. |
