style="text-indent:25px">通常狀態(tài)下，球閥在以下環(huán)境使用要特別注意：耐磨；由于硬密封球閥的閥芯是合金鋼噴焊，密封圈是合金鋼堆焊，所以硬密封球閥在開(kāi)關(guān)時(shí)不會(huì)產(chǎn)生太大的磨損。（它的硬度系數(shù)為65-70）：、密封性能好；由于硬密封球閥的密封是采用人工研磨，直到閥芯與密封圈完全吻合才能使用。所以他的密封性能是可靠的。開(kāi)關(guān)輕；由于硬密封球閥的密封圈底部采用彈簧使密封圈與閥芯緊緊抱在一起，所以在外界力量很過(guò)彈簧的預(yù)緊力時(shí)開(kāi)關(guān)非常輕。使用壽命長(zhǎng)：已普遍應(yīng)用于石油、化工、發(fā)電、造紙、原子能、航空、火箭等各部門(mén)，以及人們?nèi)粘Ｉ钪小?/p><p
