以航天伺服机构使用的充气阀为例，分析了45度分模面安装方向对O形密封圈的密封效果影响，提出了安装时45度分模面背对受力方向的安装技巧，可显著提高密封性能和生产合格率。
以航天伺服機構使用的充氣閥為例，分析瞭45度分模麵安裝方嚮對O形密封圈的密封效果影響，提齣瞭安裝時45度分模麵揹對受力方嚮的安裝技巧，可顯著提高密封性能和生產閤格率。
이항천사복궤구사용적충기벌위례，분석료45도분모면안장방향대O형밀봉권적밀봉효과영향，제출료안장시45도분모면배대수력방향적안장기교，가현저제고밀봉성능화생산합격솔。
With gas charging valves in aerospace servo-mechanisms as an example, the effect of instalation direction of a 45 degree parting line on O rings seals is ilustrated. The skil of inserting O rings with the 45 degree parting against instalation direction is proposed and verified. With this simple skil, the sealing effect and production acceptance rate have been upgraded.
