style="text-indent:25px">真空閥門(mén)引起流量不穩(wěn)定的主要原因：節(jié)流閥和單向節(jié)流閥當(dāng)節(jié)流口調(diào)整好并鎖緊后，有時(shí)會(huì)出現(xiàn)流量不穩(wěn)定現(xiàn)象，特別在小穩(wěn)定流量時(shí)更易發(fā)生。引起流量不穩(wěn)定的主要原因是鎖緊裝置松動(dòng)，節(jié)流口部分堵塞，油溫升高，以及負(fù)載壓力發(fā)生變化等。節(jié)流口調(diào)好并鎖緊后，由于機(jī)械振動(dòng)或其它原因會(huì)使鎖緊裝置松動(dòng)，使節(jié)流口過(guò)流面積改變，從而引起流量變化。油液中雜質(zhì)堆積和粘附在節(jié)流口邊上，使過(guò)流面積減小，引起流量減少。當(dāng)壓力油將雜質(zhì)沖掉后，使節(jié)流口又恢復(fù)至原有過(guò)流面積，流量也恢復(fù)至原來(lái)的數(shù)值，因此引起流量不穩(wěn)定。當(dāng)流經(jīng)節(jié)流閥的油液溫度發(fā)生變化時(shí)，會(huì)使油液的粘度發(fā)生變化，也會(huì)引起流量不穩(wěn)定；當(dāng)負(fù)載變化時(shí)，壓力隨之變化，會(huì)使節(jié)流閥的前后油液壓差發(fā)生變化，同樣也會(huì)引起流量不穩(wěn)定。防止流量不穩(wěn)定的措施，除采用防止節(jié)流閥堵塞的方法外，還可以采取加強(qiáng)油溫控制，擰緊鎖緊裝置和盡可能使負(fù)載壓力不發(fā)生變化，或少發(fā)生變化等措施。長(zhǎng)沙滑閥式真空泵真空閥門(mén)可以單獨(dú)使用，配置在真空室與真空泵之間或真空室上。</p><div

style="text-indent:25px">電磁閥卡住。電磁閥的滑閥套與閥芯的配合間隙很小(小于0.008mm)，一般都是單件裝配，當(dāng)有機(jī)械雜質(zhì)帶入或潤(rùn)滑油太少時(shí)，很容易卡住。處理方法可用鋼絲從頭部小孔捅入，使其彈回。根本的解決方法是要將電磁閥拆下，取出閥芯及閥芯套，用CCI4清洗，使得閥芯在閥套內(nèi)動(dòng)作靈活。拆卸時(shí)應(yīng)注意各部件的裝配順序及外部接線位置，以便重新裝配及接線正確，還要檢查油霧器噴油孔是否堵塞，潤(rùn)滑油是否足夠。漏氣。漏氣會(huì)造成空氣壓力不足，使得強(qiáng)制閥的啟閉困難，原因是密封墊片損壞或滑閥磨損而造成幾個(gè)空腔竄氣。</p><p style="text-indent:25px">真空的材料的放氣是真空閥門(mén)總漏量中的一個(gè)重要組成部分。氣體的來(lái)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(lái)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(lái)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(shù)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(guò)烘烤后的放氣量要極大低于未烘烤時(shí)的放氣量。真空閥門(mén)是鑄造體的時(shí)候，有可能會(huì)存在有質(zhì)量不高，閥體和閥蓋體上出現(xiàn)砂眼、松散組織、夾渣等缺陷。</p><div

style="text-indent:25px">常用真空閥門(mén)的密封部有橡膠墊圈密封結(jié)構(gòu)和金屬墊圈密封結(jié)構(gòu)。橡膠墊圈密封結(jié)構(gòu)是利用閥板與閥座壓緊橡膠墊圈，依靠橡膠的彈性變形來(lái)實(shí)現(xiàn)的密封。金屬墊圈密封結(jié)構(gòu)是依靠軟金屬受壓產(chǎn)生塑性變形而達(dá)到密封目的。橡膠墊圈密封結(jié)構(gòu)一般用于中低真空領(lǐng)域；金屬墊圈密封結(jié)構(gòu)一般用于高真空和超高真空領(lǐng)域。真空閥門(mén)的主要性能參數(shù)是導(dǎo)通率、漏氣率、開(kāi)關(guān)動(dòng)作的可靠性和準(zhǔn)確性，以及閥門(mén)的開(kāi)閉時(shí)間。閥門(mén)按照驅(qū)動(dòng)形式分為手動(dòng)和自動(dòng)兩種。自動(dòng)閥門(mén)以壓縮空氣驅(qū)動(dòng)為主，一部分小型閥門(mén)通過(guò)電磁鐵來(lái)驅(qū)動(dòng)。真空系統(tǒng)中常用的閥門(mén)大體有4種形式，即角閥、閘板閥、微調(diào)閥、放氣閥。另外，在氣路中常用到針閥和球閥。各種真空閥門(mén)根據(jù)應(yīng)用的真空領(lǐng)域和使用目的而選定。超高真空閥門(mén)要加強(qiáng)超高真空閥門(mén)的研制和開(kāi)發(fā)。武漢電磁真空閥門(mén)</p><p
