Cv為額定流量系數(shù),定義是閥門開到最大,在閥門的兩邊壓差1PSI情況下,華氏60度清水時(shí)每分鐘流經(jīng)調(diào)節(jié)閥的流量數(shù),以加侖/分計(jì)。
KV定義也是一樣,只不過(guò)單位不一樣,1BAR 的壓差,每小時(shí)流過(guò)去水的禮服數(shù)。
換算為。CV=1.167*KV
Cv決定了閥門的流通能力,通過(guò)公式可以把你現(xiàn)場(chǎng)的工藝參數(shù)計(jì)算到標(biāo)準(zhǔn)的CV數(shù)值,從而對(duì)照閥門的額定CV 進(jìn)行選擇。
Cv is the rated flow coefficient, defined as the valve open to the maximum, the pressure difference in both sides of the 1PSI valve, 60 degrees of water per minute through several flow control valve, in gallons per minute meter.
The definition of KV is the same, but the unit is not the same, 1BAR differential pressure, flow of water per hour to dress number.
The conversion is. CV=1.167*KV
Cv determines the valve flow capacity, through the formula can take CV numerical calculation process parameters on your site to the standard, so as to control the rated CV valve selection.
