    氣動球閥要怎麼控制流量呢?

    [來源:原創] [作者:admin] [日期:15-09-14] [點擊:]

    氣動球閥包括主閥體、副閥體和氣動執行器,産品的主閥體和副閥體固定連接,産品的主閥體和副閥體之間設有環形密封圈,還包括球形閥芯,産品的球形閥芯通過閥杆與氣動執行器相連接,産品的球形閥芯的一側設有與閥杆軸線平行的平面,與産品的平面相對的另一側開設有V形調節槽,産品的V形調節槽的底部與産品的球形閥芯一條直徑重合且與閥杆軸線垂直,産品的球形閥芯與産品的主閥體及副閥體之間各設有閥座,産品的氣動執行器通過支架固定在主閥體上,産品的閥杆的柱面與主閥體之間設有密封件,産品的密封件由一壓蓋壓緊。本裝置制造工藝簡單,成本低廉,密封性能好,在球形閥芯上設置V形調節槽,工作過程中可以通過調節球形閥芯旋轉的角度來控制流量。
    氣動球閥有O型球閥和V型球閥之分。O型球閥采用浮動式結構,球芯為精密鑄件,外表鍍硬鉻處理,閥座采用增強聚四氟乙烯材料,流道口與管道口徑相同,流通能力極大,流阻極小,關閉時無洩漏,一般做開關閥使用,特别适用于高粘度、V型球閥采用固定式結構,球芯上開有V型切口,可實現剪切含纖維、顆粒狀介質根據工藝設備不同可選用氣動或電動執行機構,分别組成氣動球閥和電動球閥,其中氣動球閥如要實現比例調節須配閥門定位器電動球閥如要實現比例調節須選電子式電動執行機構或配伺服放大器等。 從材質上,可以分為:碳鋼球閥,不鏽鋼304球閥,316球閥和銅球閥 ;按壓力,可以分為:高壓球閥和低壓球閥 低壓氣動球閥;主要應用在介質為水等腐蝕性管路上!
