V型調節球閥[Fa]是球[Qiu]閥的一種,它的(De)關閉件是半球(Qiu)體上開有V 字型開[Kai]口,V型開口具[Ju]有鋒利的刃口[Kou],在球體回轉過程中,關(Guan)閉(Bi) 件之間有擦拭作(Zuo)用,對介質具有強[Qiang]有力(Li)的切斷(Duan)力,球體的V型(Xing)開 口與閥座[Zuo]流道形成一個[Ge]扇形區(Qu)域[Yu],在回轉過程中可改變流道截 面積,形成對(Dui)介質的精确調節,它是一種角回轉的調[Diao]節閥,其 密封(Feng)性能與[Yu]普通球閥相同(Tong),使它同時具備調節[Jie]和開(Kai)關兩種[Zhong]功能, 與氣動[Dong]或電動執行器配套,廣泛使用于工業過程自控系統中。
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.
