絲扣止回閥
【簡單介紹】
【詳細(xì)說明】
內(nèi)螺紋止回閥:閥瓣沿著閥體垂直中心線滑動的止回閥,內(nèi)螺紋止回閥只能安裝在水平管道上,在高壓小口徑止回閥上閥瓣可采用圓球。蝶式止回閥的閥體形狀與截止閥一樣(可與截止閥通用),因此它的流體阻力系數(shù)較大。其結(jié)構(gòu)與截止閥相似,閥體和閥瓣與截止閥相同。閥瓣上部和閥蓋下部加工有導(dǎo)向套簡,閥瓣導(dǎo)向簡可在閥盞導(dǎo)向簡內(nèi)自由升降,當(dāng)介質(zhì)順流時,閥瓣靠介質(zhì)推力開啟,當(dāng)介質(zhì)停流時,閥瓣靠自垂降落在閥座上,起阻止介質(zhì)逆流作用。直通式蝶式止回閥介質(zhì)進出口通道方向與閥座通道方向垂直;立式升降式止回閥,其介質(zhì)進出口通道方向與閥座通道方向相同,其流動阻力較直通式小。止回閥只用于介質(zhì)單向流動的管路上,阻止介質(zhì)回流,以防發(fā)生事故。
適用介質(zhì)為:水、油品、蒸汽、酸性介質(zhì)等。
