結(jié)構(gòu)特點(diǎn)
(1).國(guó)標(biāo)截止閥設(shè)計(jì)制造按國(guó)家標(biāo)準(zhǔn)GB/T 12235,結(jié)構(gòu)合理,密封可靠,性能優(yōu)良,造型美觀。
(2).閥瓣、閥座密封面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(zhǎng)。
(3).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。
(4).可采用各種配管法蘭標(biāo)準(zhǔn)及法蘭密封面形式,滿足各種工程需要和用戶要求。
(5).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,填料與日俱更換可在不停機(jī)情況下進(jìn)行方便快捷不影響系統(tǒng)運(yùn)行。
