進(jìn)口氣動(dòng)高壓球閥特點(diǎn)Characteristic
全流量流通，啟閉迅速,從全開到全關(guān)只要旋轉(zhuǎn)90° Full flowcirculation, quick opening and closing, and 90 ° rotation from full opening tofull closing
流體阻力小，全通徑的球閥基本沒有流阻The fluid resistance is small, and the fullbore ball valve basically has no flow resistance
耐高壓，啟閉迅速,扭矩低，無泄漏，不需要手工重調(diào)密封件 Highpressure resistance, quick opening and closing, low
緊密可靠,密封面材料為PTFE，密封性好，能實(shí)現(xiàn)完全密封。在真空系統(tǒng)中也已廣泛使用 Tightatorque, no leakage, no need to manually readjust the sealsnd reliable, thesealing surface material is PTFE, with good sealing performance, and canachieve complete sealing. It has also been widely used in vacuum systems
在全開或全閉時(shí)，球體和閥座的密封面與介質(zhì)隔離，介質(zhì)通過時(shí)，不會(huì)引起閥門密封面的侵蝕When the valve is fully opened or closed, thesealing surfaces of the ball and valve seat are isolated from the medium. Whenthe medium passes through, it will not cause erosion of the valve sealingsurface
