二、调压器的工作能力的估算

Estimation of the regulator operation ability

最大工作能力定义:对于规定的介质,在设计的进出口压力下,调压器的阀口完全打开时的工作能力。

Defines the maximum capacity: provisions of the media, in the design of the import and export pressure, pressure regulator valve is fully open working ability.

可用流量系数(KG)来衡量调压器工作能力的大小:

Available flow coefficient ( KG ) to measure the regulator operation ability: KG(C2)的物理含义是:在标准状态下,介质为天然气(密度=0.38kg/m3(RMG)、0.78kg/m3(ELSTE)、0.72kg/m3(TARTARINI) ),进口压力为1bar(相对),出口压力为常压,调压器的最大工作能力。

KG ( C2 ) physical meaning is: in the standard state, medium is natural gas ( density =0.38kg/m3 ( RMG ), 0.78kg/m3 ( ELSTE ), 0.72kg/m3 ( TARTARINI ) ), 1bar ( relative ) inlet pressure, outlet pressure is atmospheric pressure, the maximum working capacity regulator.
