| Abstract: | According to the structural features and seal requirements of the valve disc, the seal mechanization of the valve disc is analyzed comprehensively. A conclusion that the specific pressure should exceed the pressure of the medium was obtained. The research on heat pressing technology of the fluorocarbon valve disc was carried out to seek out right parameters. A formula to compute specific pressure of the valve disc is offered in this paper. The seal specific pressure of valve disc made by heat pressing technology can meet the theoretical and design requirements. The product passed the test and flight assessment. |
