J941H精小型電動截止閥結構特點、用途及注意事項
SANSE雙雄閥門可以安裝在管道的任何位置上,介質從下往上流,產品設計制造按國家標準GB12235結構合理,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的管道上,有良好的防腐性的足夠的強度 。
精小型電動截止閥其特點如下:
① 閥瓣、閥座密封面用硬質合堆焊而成,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,能適用于各種壓力、溫度及介質工況。
⑤ 安裝閥門時注意介質的流向,嚴格按閥門流...
