关于full area trim 与 0.4 factor trim? 在 Masoneilan Regulators Steam,Gas,or Liquid Service Model 525 and 526 样本第5页上有这么一句话: This Regulator Capacity Table is based on full area trim. Multiply capacity by 0.4 when using (0.4) facotor trim 这句话是什么意思? 在第四页有一个表,我打出来,供大家参考: Flow Coefficients-Rated Cv Trim Size 1/2 3/4 1 1 1/2 Full area 2.7 6 9 21 0.4 Factor ---- --- 3.6 critical flow factor- FL Full area trim-FL=0.9 0.4 facotr trim-FL=0.95 ( 注: "L "为下标 ) 另:关于CV的定义,可参阅: http://www.kongf.com/bbs/dispbbs.asp?boardid=87&Id=7490 查看更多2个回答 . 3人已关注
