產品概述
一、J41F襯氟截止閥概述：
截止(zhi)閥(fa)是指關閉件（閥(fa)瓣）由閥(fa)桿帶動(dong)并沿閥(fa)座(zuo)中心軸線(xian)做(zuo)升(sheng)降(jiang)運(yun)動(dong)的(de)閥(fa)門，在管路(lu)上主要用來接通或(huo)截止(zhi)斷管路(lu)中的(de)介質，但不能做(zuo)節流用。
二、J41F襯氟截止閥基本結構：
1.氟塑料全襯里J41F46型直通式、J45F46型直流式、J44F46型角式截止閥，具有結構緊湊、啟閉靈活、耐腐蝕性能強，行程短（一般為公稱通徑1/4）等項優點，被廣泛應用在石油、化工等管路系統中做截斷介質用，但需要強調的是氟塑料襯里的截止閥嚴禁用做流量調節，以免節流口處產生的高速介質流沖蝕 破壞密封面。
2.閥瓣與閥桿設計為一體結構，用以防止由于管路壓力波動造成內件沖出閥體的可能性，結構緊湊，使用安全。
