角式襯氟截止閥-J44F46角式襯氟截止閥具有結(jié)構(gòu)緊湊、啟閉靈活、耐腐蝕性能強(qiáng)，行程短（一般為公稱(chēng)通經(jīng)1/4）等優(yōu)點(diǎn)。被廣泛應(yīng)用在石油、化工等管路系統(tǒng)中做截?cái)嘟橘|(zhì)用，但塑料襯里的截止閥嚴(yán)禁用做流量調(diào)節(jié)，以免節(jié)流口處產(chǎn)生的高速介質(zhì)流沖蝕破壞密封面。閥瓣與閥桿設(shè)計(jì)為一體結(jié)構(gòu)，用以防止由于管路壓力波動(dòng)造成內(nèi)件沖出閥體的可能性，結(jié)構(gòu)緊湊，使用安全。
設(shè)計(jì)規(guī)范遵循GB/T 12233，GB/T12235，ANSI B 16.34標(biāo)準(zhǔn)
驅(qū)動(dòng)方式手動(dòng)、蝸輪轉(zhuǎn)動(dòng)、氣動(dòng)(常開(kāi)或常閉)、電動(dòng)
