原裝進口截止閥|進口截止閥品牌|進口截止閥上海樹典閥門
截止閥、上海樹典閥門: 的啟閉件是塞形的閥瓣,密封面呈平面或錐面,閥瓣沿流體的中心線作直線運動。閥桿的運動形式,有升降桿式(閥桿升降,手輪不升降),也有升降旋轉(zhuǎn)桿式(手輪與閥桿一起旋轉(zhuǎn)升降,螺母設(shè)在閥體上)。截止閥只適用于全開和全關(guān),不允許作調(diào)節(jié)和節(jié)流。 截止閥屬于強制密封式閥門,所以在閥門關(guān)閉時,就要閥瓣施加壓力,以強制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進入閥六時,操作力所需要克服的阻力,是閥桿和填料的磨擦力與由介質(zhì)的壓力所產(chǎn)生的推力,關(guān)閥門的力比開閥門的力大,所以閥桿的直徑要大,否則會發(fā)生閥桿頂彎的故障。近年來,從自密封的閥門出現(xiàn)后,截止閥的介質(zhì)流向就改由閥瓣上方進入閥腔,這時在介質(zhì)壓力作用下,關(guān)閥門的力小,而開閥門的力大,閥桿的直徑可以相應(yīng)地減少。同時,在介質(zhì)作用下,這種形式的閥門也較嚴密電話:021-54094367/51877628 手機18916979927 傳真:54094227 E-mail:651292261@qq.com
