J41F3/J45F3-J44F3襯氟塑料里截止閥
J41F3/J45F3-J44F3襯氟塑料里截止閥介紹:
J41F3/J45F3-J44F3襯氟塑料里截止分為:直通式襯氟截止閥、直流式襯氟截止閥、角式襯氟截止閥,具有結(jié)構(gòu)緊湊、啟閉靈活、耐腐蝕性強(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)作用,但需要強(qiáng)調(diào)的是襯氟截止閥嚴(yán)禁做流量調(diào)節(jié),以免節(jié)流口出產(chǎn)生的高速介質(zhì)流沖蝕破壞密封面。
J41F3/J45F3-J44F3襯氟塑料里截止閥特點(diǎn):
1、塑料襯里J41型直通式、J45型直溜式、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。
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。
