style="text-indent:25px">真空閥門(mén)是在真空系統(tǒng)中用來(lái)隔離（切斷）氣流、調(diào)節(jié)氣流流量、分配氣流的真空元件。種類(lèi)繁多的真空裝置（亦稱(chēng)真空工程設(shè)備）都離不開(kāi)真空系統(tǒng)。真空閥門(mén)不論在簡(jiǎn)單或復(fù)雜的真空系統(tǒng)中都占有重要的地位。通常在真空系統(tǒng)設(shè)計(jì)時(shí)，要根據(jù)真空裝置的要求和真空系統(tǒng)的特點(diǎn)來(lái)選擇不同類(lèi)型的真空閥門(mén)。例如，真空放氣閥，是用來(lái)給真空系統(tǒng)放入大氣用的。真空裝置完成真空作業(yè)后，若要更換工件或取出樣品，必須將大氣放入真空室，使真空室大門(mén)兩側(cè)沒(méi)有壓差，才能打開(kāi)大門(mén)進(jìn)行工件更換。而針閥是向真空系統(tǒng)中充氣，并能調(diào)節(jié)氣體流量的真空閥門(mén)。</p><p style="text-indent:25px">如何正確地選用各種真空閥門(mén)？真空閥門(mén)種類(lèi)的不同，適用的場(chǎng)合也不同，下面就閘閥、截止閥、蝶閥、球閥等不同種類(lèi)的閥門(mén)，講敘閥門(mén)的特性及常用區(qū)域。還根據(jù)使用要求的不同如何選擇閥門(mén)，比如按照按防止介質(zhì)倒流選用閥門(mén)、按調(diào)節(jié)介質(zhì)參數(shù)選用閥門(mén)。閘閥的介紹及選型：閘閥是作為截止介質(zhì)使用，在全開(kāi)時(shí)整個(gè)流通直通，此時(shí)介質(zhì)運(yùn)行的壓力損失比較小。閘閥通常適用于不需要經(jīng)常啟閉，而且保持閘板全開(kāi)或全閉的工況。不適用于作為調(diào)節(jié)或節(jié)流使用。對(duì)于高速流動(dòng)的介質(zhì)，閘板在局部開(kāi)啟狀況下可以引起閘門(mén)的振動(dòng)，而振動(dòng)又可能損傷閘板和閥座的密封面，而節(jié)流會(huì)使閘板遭受介質(zhì)的沖蝕。從結(jié)構(gòu)形式上，主要的區(qū)別是所采用的密封元件的形式。根據(jù)密封元件的形式，常常把閘閥分成幾種不同的類(lèi)型，如：楔式閘閥、平行式閘閥、平行雙閘板閘閥、楔式雙閘板閘等。比較常用的形式是楔式閘閥和平行式閘閥。如果真空閥門(mén)系機(jī)械待動(dòng)，要按時(shí)對(duì)變速箱添加潤(rùn)滑油。</p><div
