J941H-16C DN125電動截止閥
簡介
J941H電動截止閥屬于強制密封式閥門,所以在閥門關閉時,必須向閥瓣施加壓力,以強制密封面不泄漏。當介質由閥瓣下方進入閥門時,操作力所需要克服的阻力,是閥桿和填料的摩擦力與由介質的壓力所產生的推力,關閥門的力比開閥門的力大,所以閥桿的直徑要大,否則會發生閥桿頂彎的故障。近年來,從自密封的閥門出現后,截止閥的介質流向就改由閥瓣上方進入閥腔,這時在介質壓力作用下,關閥門的力小,而開閥門的力大,閥桿的直徑可以相應地減少。同時,在介質作用下,這種形式的閥門也較嚴密。我國閥門“三化給”曾規定,截止閥的流向,一律采用自上而下。
結構特點
1、選材考究,符合國內、外相關標準,結構合理,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、閥桿經調質及表面氮化處理,有良好的抗腐蝕性和抗擦傷性。
5、可采用各種配管法蘭標準及法蘭密封面型式,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行,方便快捷,不影響系統運行。
8、配有DZW系列多回轉式電動裝置,具有殼體小,重量輕,功能全,并可與遠程電腦配套使用,也可按用戶要求選配電動裝置。
