V型調節球閥是球閥的一種，它的關閉[Bi]件是半球體上開有V 字型開(Kai)口，V型開口具(Ju)有鋒利的刃口，在球(Qiu)體回[Hui]轉過程中，關閉 件之間有擦拭作用，對介質具有強有力(Li)的切斷力，球體的V型開 口(Kou)與閥(Fa)座流道形[Xing]成一個扇形區域，在回轉過程[Cheng]中可改變流(Liu)道截 面積，形[Xing]成對(Dui)介質的(De)精确調節，它(Ta)是一種角回[Hui]轉的調節閥，其 密封性能與普通球閥相同(Tong)，使它同時具備(Bei)調節和開[Kai]關兩種功能， 與氣動(Dong)或電動執行器配套，廣泛[Fan]使用于工業(Ye)過程自[Zi]控系統中(Zhong)。 

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.
