style="text-indent:25px">擇真空閥門的密封結(jié)構(gòu)時(shí)應(yīng)注意以下幾點(diǎn)：a.盡可能減少閥板下高真空側(cè)的放氣因素，例如選用放氣率小的密封墊材料等.b.關(guān)閥后密封圈截面上有比較大的壓縮變形.c.結(jié)構(gòu)力求簡(jiǎn)單；d.制造方便；e.密封元件便于拆卸和修理。閥門關(guān)閉的密封性能好壞決定于密封墊填塞閥座表面不平的程度。影響這種填塞程度的因素有二方面：a.密封墊材料的硬度和壓緊程度；b.閥座表面的粗糙度。通常閥座表面的粗度都高于3.2/Δ，密封墊的硬度都在邵氏硬度55～75之間。密封墊的壓緊程度，根據(jù)試驗(yàn)結(jié)果，當(dāng)橡膠的硬度在邵氏硬度50以上，而表面沒有任何擦傷時(shí)，橡膠墊的高度壓縮比在15%以上就能達(dá)到漏氣率小于1.33×10-7Pa·L/s·cFn。的密封性能。如果考慮到制造精度上允許的偏差·把壓縮比適當(dāng)提高一些是必要的。因此建議真空閥門密封墊的相對(duì)壓縮比通常取為15%～25%。手動(dòng)超高真空擋板閥系列等十多種真空閥門產(chǎn)品。</p><div

style="text-indent:25px">真空的材料的放氣是真空閥門總漏量中的一個(gè)重要組成部分。氣體的來源主要有：吸附于真空閥零件內(nèi)表面的氣體；從金屬內(nèi)部擴(kuò)散出來的氣體以及金屬表面因發(fā)生某種化學(xué)反應(yīng)而釋放出來的氣體。1、不銹鋼的放氣量很小。只及銅的1/10左右，與鋁相比，則*為它的1/100左右；2、橡膠與樹脂的放氣量比金屬材料都要高出100倍左右，比較高的如硅橡膠則要高出1000倍以上。放氣現(xiàn)象與溫度有關(guān)，溫度越高，放氣速率越大。因此用加熱方法除氣是一種十分有效的手段，材料經(jīng)過烘烤后的放氣量要極大低于未烘烤時(shí)的放氣量。根據(jù)材料有不銹鋼、碳鋼、鋁合金為主體材料的真空閥門。合肥GUD型-電動(dòng)高真空球閥</p><p
