v型(xíng)調節(jiē)球閥是球(qiú)閥的(de)一種，它的(de)關閉(bì)件(jiàn)是半球體上開有v 字型(xíng)開(kāi)口，v型開口具(jù)有鋒利的刃口，在球體回轉過(guò)程中，關閉 件之(zhī)間有擦(cā)拭作用(yòng)，對介質(zhì)具(jù)有強(qiáng)有力的(de)切斷力，球體(tǐ)的v型(xíng)開 口與閥座流(liú)道形(xíng)成一(yī)個扇形區(qū)域(yù)，在(zài)回轉(zhuǎn)過程(chéng)中可改變(biàn)流道截 面積，形(xíng)成對(duì)介質的精确調(diào)節，它(tā)是一種角(jiǎo)回轉的調節閥(fá)，其 密封(fēng)性(xìng)能與普通球閥(fá)相同(tóng)，使它同時具備(bèi)調節和開(kāi)關兩(liǎng)種功(gōng)能， 與(yǔ)氣動(dòng)或電動執行(háng)器(qì)配套，廣泛使用(yòng)于工業過(guò)程自(zì)控系(xì)統中。 

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.
