V型調節球閥是球閥的一種,它的關閉件是半球體上開有V 字型開口,V型開口具有鋒利的刃口,在球體回轉過程中,關閉 件之間有擦拭作用,對介質具有強有力的切斷力,球體的V型開 口與閥座流道形成一個扇形區域,在回轉過程中可改變流道截 面積,形成對介質的精確調節,它是一種角回轉的調節閥,其 密封性能與普通球閥相同,使它同時具備調節和開關兩種功能, 與氣動或電動執行器配套,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.
