Cv為額定流量系數,定義是閥門開到最大,在閥門的兩邊壓差1PSI情況下,華氏60度清水時每分鐘流經調節閥的流量數,以加侖/分計。
KV定義也是一樣,只不過單位不一樣,1BAR 的壓差,每小時流過去水的禮服數。
換算為。CV=1.167*KV
Cv決定了閥門的流通能力,通過公式可以把你現場的工藝參數計算到標準的CV數值,從而對照閥門的額定CV 進行選擇。
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.
