1、j941電動法蘭截止閥結(jié)構(gòu)特點、用途及注意事項
可以安裝在管道的任何位置上,介質(zhì)從下往上流。產(chǎn)品設(shè)計制造按國家標(biāo)準(zhǔn)GB12235,結(jié)構(gòu)合理,密封可靠,性能優(yōu)良,造型美觀。合金鋼截止閥適用于耐高溫的蒸汽、油品管道上,具有耐高溫特點。不銹鋼截止閥適用于各類腐性介質(zhì)的管道上,有良好的防腐性的足夠的強度。
j941電動法蘭截止閥其特點如下:
①閥瓣、閥座密封面用硬質(zhì)合堆焊而成,耐磨、耐高溫、耐腐蝕、抗擦傷性好、使用壽命長。
②閥桿材料為滲氮鋼,滲氮后的閥桿表面硬度高、耐磨、抗擦傷,抗腐蝕。
③由于溫度、壓力等原因,閥門口徑DN50以下的閥體、閥蓋為模鍛件、DN65以上的閥體、閥蓋為鑄鋼件。
④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,能適用與各種壓力、溫度及介質(zhì)工況。
⑤安裝閥門時注意介質(zhì)的流向,嚴(yán)格按閥門流向箭頭指示的方向安裝。
⑥電動截止閥盡量垂直安裝,閥桿向上。
