v型(xíng)調節球閥是球(qiú)閥的一種(zhǒng)，它的關閉件(jiàn)是半球體上開有v 字型開(kāi)口，v型開口具(jù)有鋒利的刃(rèn)口(kǒu)，在球(qiú)體回(huí)轉過程中，關閉 件之(zhī)間有擦(cā)拭作用，對介質具(jù)有強(qiáng)有力的切斷力，球體的(de)v型(xíng)開 口與閥座(zuò)流(liú)道形成一(yī)個扇(shàn)形區(qū)域，在回轉過程(chéng)中可改變流道截 面(miàn)積，形(xíng)成對介質(zhì)的精确調節，它(tā)是(shì)一種角(jiǎo)回(huí)轉(zhuǎn)的調(diào)節閥(fá)，其 密(mì)封(fēng)性能與(yǔ)普通球閥相同(tóng)，使它(tā)同時(shí)具備(bèi)調節和(hé)開關兩種功能， 與(yǔ)氣動(dòng)或電動執(zhí)行器配套，廣泛使用(yòng)于工業(yè)過程自控系統(tǒng)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.
