V型調節球閥是球閥的一種，它的關閉件是半球(qiú)體上開有V 字型開(kāi)口，V型開口具(jù)有鋒利的刃(rèn)口，在球體回轉(zhuǎn)過(guò)程中，關閉 件之間有擦(cā)拭作用，對介質具有強(qiáng)有力的切斷力，球體的(de)V型(xíng)開 口與閥座流道形(xíng)成一個扇形區域，在回轉過程中可改變流道截 面積，形成對介質的精确調節，它是一種角回轉的調節閥，其 密封性能與普通球閥(fá)相同，使它同時具備調節(jiē)和開關兩種功能， 與氣動(dòng)或電動執行器配套，廣泛使用于工業過程自控系統中(zhōng)。 

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.
