J41F、J44F、F45F襯氟里截止閥
一、基本結(jié)構(gòu)
1、塑料襯里J41型直通式、J45型直流式、J44型角式截止閥,具有結(jié)構(gòu)緊湊、啟閉靈活、耐腐蝕性能強(qiáng),行程短(一般為公稱通徑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。2、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。
二、設(shè)計(jì)規(guī)范:遵循GB/T12233,GB/T12235,ANSI B16.34標(biāo)準(zhǔn)
三、驅(qū)動(dòng)方式:手動(dòng)、蝸輪傳動(dòng)、氣動(dòng)(常開或常閉)、電動(dòng)
