JY41W-40R-DN300,JY41W-40R-DN400,不銹鋼氧氣截止閥
JY41W不銹鋼氧氣截止閥采用材質(zhì)優(yōu)良的硅黃銅或不銹鋼鑄造而成,具有機(jī)械強(qiáng)度高,耐磨損、安全性好等優(yōu)點(diǎn)。使用在氧氣管路上,具有**的防爆阻燃性能,消除了氧氣管路上的不安全因素。
氧氣截止閥屬于強(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。近年來,從自密封的閥門出現(xiàn)后,法蘭截止閥的介質(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。我國閥門“三化給”曾規(guī)定,截止閥的流向,一律采用自上而下。
