一、產品概述:上裝偏心半球閥結構設計類似三偏心硬密封蝶閥,具有操作輕便、開啟過程幾乎無磨擦、零泄漏、壽命長等優點。
二、產品特征:
1.壓力損失?。喝_時水損幾乎為零,流道暢通,且介質不會沉積在閥體中腔內;
2.耐顆粒磨損:V形開口的球冠與金屬閥座之間具有剪切作用,于在關閉過程中,只在刻球冠才靠向閥座,不形成磨擦,且閥座用耐磨的鎳合金制成,不易被沖刷磨損,因而適用于含纖維,微小固體顆粒,漿等;
3. 壽命長:無易損部件,由于偏心作用,于閥門啟閉時密封面間無磨擦,則使用壽命長;
4.維修方便:閥門維修時不需從管路上拆下,只要打開閥蓋即可進行維修;
5.廣泛適用不著水,污水,含微小固體顆粒,水,蒸汽,煤氣,開然氣,油品等。
