v型球阀流量特性/系数/曲线

V 型球阀是球阀的一种，它的关闭件是半球体上开有V字型开口. V 型开口具有锋利的刃口，在球体回转过程中，关闭件之间有擦拭作用，对介质具有强有力的切断力，球体的V型开口与阀座流道形成一个扇形区域，在回转过程中可改变流道裁面积，形成对介质的精确调节，它是一种角回转的调节阀， 其密封性能与普通球阀相同，使它同时具备调节和开关两种功能，与气动或电动执行器配套，广泛使用于工业过程自控系统中。

The segment ball valve is a kind of ball valve with a hemisphere of V-shaped opening as closing part.V-shaped opening has a sharp edge provides a wiping between the closing parts while rotating,andit has a sharpcutoffto the medium.V-shaped opening portand the valve seatformafan-shaped areato change the port cross area,creating a precision adjustment of medium during rotary.It is a kind of adjusting valve with angle rotation, with the same seal performance as common  ball valve,which  makes  it  have a combination of regulation and on-off functions,equipped with  pneumatic or electric actuators,being widely used in industrial process auto-controlsystem.
