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%。</p><p
