原污水泵浦系統O500橡膠閥瓣逆止閥消除水鎚改進計算

Rubber Flapper Swing Check Valve

摘要


本案是大尺寸的逆止閥計算起來更不容易,無論法規方面要考慮符合業主規定的ASME code,SecⅡ、Sec Ⅷ及AISC code外,或可按一般的機械設計來做設計,逆止閥使用時各零組件所承受的工作應力各自不同,諸如彎曲力矩、剪力、壓力、拉力以及扭轉力矩等,承包商為確保設計及製造施工之成功,不但要節約製造及施工成本,而且一定要確保在動水使用中,各零組件能承受各組合應力,並能確保使用壽命,可見設計工作是工程是否成功的首要關鍵。

It is not so easy to analyze the dynamic strength of the check valve under high dynamic pressure, complicate situations. The design has not only to meet the requirements of ASME and AISC Code set forth by owner, but also apply the general mechanical engineering practice, to guarantee the product quality and have had profit. Therefore the mechanical engineering design plays a very important role in whether the product succeeded or not, because the equipment will be operating by owner day and night.
