R412006257-AVENTICS氣動(dòng)截止閥
AVENTICS氣動(dòng)截止閥屬于強(qiáng)制密封式閥門，所以在閥門關(guān)閉時(shí)，必須向閥瓣施加壓力，以強(qiáng)制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥六時(shí)，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(kāi)閥門的力大，所以閥桿的直徑要大，否則會(huì)發(fā)生閥桿頂彎的故障。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(jìn)入閥腔，這時(shí)在介質(zhì)壓力作用下，關(guān)閥門的力小，而開(kāi)閥門的力大，閥桿的直徑可以相應(yīng)地減少。同時(shí)，在介質(zhì)作用下，這種形式的閥門也較嚴(yán)密。我國(guó)閥門"三化給"曾規(guī)定，截止閥的流向，一律采用自上而下。
