J6S41H氣動帶手動截止閥屬于強制密封式閥門,氣動閥門關(guān)閉時,必須向閥瓣施加壓力,以強制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥瓣時,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。截止閥的介質(zhì)流向就改由閥瓣上方進(jìn)入閥腔,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(yán)密。

J6S41H氣動帶手動截止閥結(jié)構(gòu)特點:
1、選材考究,符合國內(nèi)、外相關(guān)標(biāo)準(zhǔn),結(jié)構(gòu)合理,造型美觀。
2、閥瓣、閥座密封面采用鐵基合金堆焊或司太立(Stellite)鈷基硬質(zhì)合金堆焊而成,耐磨、耐高溫、耐腐蝕、抗擦傷性能好,使用壽命長。
4、閥桿經(jīng)調(diào)質(zhì)及表面氮化處理,有良好的抗腐蝕性和抗擦傷性。
5、可采用各種配管法蘭標(biāo)準(zhǔn)及法蘭密封面型式,滿足各種工程需要及用戶要求。
6、閥體材料品種齊全,填料、墊片可根據(jù)實際工況或用戶要求合理選配,能適用于各種壓力、溫度及介質(zhì)工況。
7、倒密封采用螺紋連接密封座或本體堆焊奧氏體不銹鋼而成,密封可靠,更換填料可在不停機情況下進(jìn)行,方便快捷,不影響系統(tǒng)運行。
