style="text-indent:25px">真空閥門的特性：主要是指真空閥門外殼對(duì)大氣的真空密封性，衡量真空密封性的性能主要有兩個(gè)技術(shù)指標(biāo)，即真空閥門的流導(dǎo)和真空閥門的閥座漏氣率（簡(jiǎn)稱漏率）。1、真空閥門的流導(dǎo)在閥門打開(kāi)狀態(tài)下的氣體流動(dòng)的流導(dǎo)。需要指出的是，在樣本中，真空閥門的流導(dǎo)通常以“當(dāng)量管長(zhǎng)度”列出，這里設(shè)管的公稱尺寸與閥門的公稱尺寸相同。2、真空閥門的閥座漏氣率在關(guān)閉狀態(tài)下由閥座漏入的氣體流率。它取決于氣體種類、壓力、溫度和閥門進(jìn)、出口的壓差。</p><p style="text-indent:25px">真空閥門維修工作一般有主要內(nèi)容：①閥的清洗——檢修從工藝管線上拆開(kāi)下來(lái)的閥，把它上面所有被工藝介質(zhì)浸漬過(guò)的零部件清洗潔凈。以免某些有腐蝕性或其他傷害作用的流體對(duì)人和設(shè)備形成丟失。一起應(yīng)零部件顯露外表的銹蝕。②電動(dòng)單座調(diào)節(jié)閥的拆開(kāi)——為了對(duì)全體零部件作查看以決議修補(bǔ)和替換的范圍。首要應(yīng)把執(zhí)行組織和閥卸開(kāi)。拆開(kāi)時(shí)保護(hù)好經(jīng)過(guò)精細(xì)加工如閥芯、閥座、閥桿、推桿、軸套等零件以及所有零部件的精細(xì)加工面，防止損壞，以使檢修費(fèi)用低，拆開(kāi)閥座應(yīng)該用**工具。③主要零部件的檢修——電動(dòng)單座調(diào)節(jié)閥閥芯的節(jié)流外表以及閥芯和閥座的密封面如有小的銹斑和磨損。尚可用一般的機(jī)械加工和研磨方法來(lái)修。假如損壞嚴(yán)重，則替換新的零件。修補(bǔ)時(shí)要求保證好閥芯和閥座的同軸度。氣動(dòng)高真空蝶閥的優(yōu)點(diǎn)：氣動(dòng)高真空蝶閥的主要優(yōu)點(diǎn)，結(jié)構(gòu)簡(jiǎn)單，體積小重量輕，造價(jià)低。</p><div
