style="text-indent:25px">在真空閥門設(shè)計(jì)中，材料的冷焊是一個(gè)不可回避的問題，它可能出現(xiàn)在密封面上、法蘭連接處以及螺紋副上。這種冷焊的機(jī)理是，在真空情況下，特別是在超高真空情況下，金屬表面會(huì)失去吸氣層，吸氣層的消失會(huì)導(dǎo)致金屬表面摩擦因數(shù)增加，這樣就有可能造成金屬接觸表面局部或全部焊住。例如，如果把一塊銅試樣置于超高真空系統(tǒng)中，用幾千千克力把它拉斷，再用50～100kgf使其斷開合在一起，結(jié)果裂縫會(huì)自行消失，裂縫處的強(qiáng)度仍可達(dá)到原來強(qiáng)度的96%左右。其他材料也有與此相似的現(xiàn)象。GUQ型-氣動(dòng)高真空球閥生產(chǎn)真空閥門應(yīng)保持清潔并存放在干燥室內(nèi)。</p><div
