V型調節球閥是球閥的一種(zhǒng)，它的關閉件是半球(qiú)體上開有V 字型開口，V型開口具有鋒利的刃口，在球體回轉(zhuǎn)過程中，關閉 件之間有擦拭作用(yòng)，對介質具有強(qiáng)有力的切斷力，球體的V型開 口與閥座流道形成一(yī)個扇形區域，在回轉過程中可改變流(liú)道截 面積，形(xíng)成(chéng)對介質的精(jīng)确調節，它(tā)是一種角(jiǎo)回轉的調節閥，其 密封(fēng)性能與普通球閥(fá)相同(tóng)，使它同時具備調節和開關兩種功能， 與氣動或(huò)電動執行器(qì)配套(tào)，廣泛使用于工業(yè)過程自(zì)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.
