一、『產品描述』
進口高壓法蘭鍛鋼球閥所有部件均為鍛件,采用下裝式閥桿,設備倒密封結構,采用鑲嵌式閥座,閥座背后設備O型圈,確保介質不外漏,密封面采用尼龍 1010,它的磨擦系數通常為巴氏合金的1/3,因此它是一種自然滑性材料。但抗彎曲強度和沖擊強度及較高的延性,與金屬不相上下。
Imported high pressure flange forging steel ball valveproducts all parts are forging, by downloading the stem,equipment fall airproof structure, adopts an embeddedvalve seat, seat O - ring behind equipment, to ensure thatthe media does not leak, sealing surface with nylon 1010,coefficient of friction, it usually Babbitt alloy 1/3, so it is anatural slide materials. But the ductility of flexural strength and impact strength and higher, and the metal be roughly the same.
二、進口法蘭高壓鍛鋼球閥工作原理:
進口法蘭高壓鍛鋼球閥是用帶有圓形通道的球體作啟閉件,球體隨閥桿轉動實現啟閉動作的閥門,既正向旋轉1/4圈(90°)時,閥關斷。反向旋轉1/4圈(90°)時,閥開啟。。球閥的啟閉件是一個有孔的球體,繞垂直于通道的軸線旋轉,從而達到啟閉通道的目的。球閥主要供開啟和關閉管道和設備介質之用。
三、進口法蘭高壓鍛鋼球閥具有以下優(yōu)點:
1、進口法蘭高壓鍛鋼球閥所有部件均為鍛件
2、采用下裝式閥桿,設備倒密封結構
3、采用鑲嵌式閥座,閥座背后設備O型圈,確保介質不外漏
4、密封面采用尼龍或聚四氟乙烯,它的磨擦系數通常為巴氏合金的1/3,因此它是一種自然滑性材料。但抗彎曲強度和沖擊強度及較高的延性,與金屬不相上下。
