V型调节球阀是球阀的一种，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截 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。 

Of V-type regulating ball valve is a kind of ball valve， it shutdown a is half sphere has aV opening， v-shaped opening has a sharp edge， in the process of rotating sphere， wiping， between the closed to the media has a strong cutting force， the sphere of the v-shaped opening port to form a fan-shaped area， with the valve seat can change the port area， in the process of rotary forming of medium precision adjustment， it is a kind of Angle of rotation of the regulator， the same as the common ball valve sealing， make it have a combination of regulation and switch two functions， equipped with pneumatic or electric actuators， widely used in industrial process control system.
