The calculation of valve's KV can therefore be related to the pressure loss Conversion tool kV KVS and CV valve in mecaflux.This tool is used to test the authority of a valve for a section, which you computed the head loss, or to establish the KV or KVS or CV of a valve...
Flow field through a gate valve installed in a circular pipe and loss coefficient the gate-plate height, which is the height from the inner-wall surface to the head along the center line of the valve plate, to the pipe diameter... H Yamada,Y Nakahara,T Tsuchiya - 《Transactions of the...
上述方法能够有效的解决目前国内抽水蓄能电站主球阀过流特性试验数据缺乏的问题.%The flow coefficient of ball valve in pumped storage power station is the basic data of main valve involving in load rejection research, and it also directly affects the magnitude and change of hammer pressure of water ...
level by eliminating the restrictive valve seat and substantially increasing the valve’s open area and flow coefficient (Cv). They are ideal for application in vacuum pumps, compressed air and gas systems as well as in water systems where low head loss and elimination of water hammer are ...
