style="text-indent:25px">氣動(dòng)高閥的安裝事項(xiàng)；1.打開包裝，首先檢查氣動(dòng)高真空擋板閥表面是否完整無損，查看氣缸是否完好無損無裂痕，并查看電磁閥電壓是否和訂貨時(shí)電壓一致。2.查看高真空擋板閥連接法蘭是否與訂貨時(shí)尺寸一致，法蘭連接密封面和閥腔閥座密封面是否光滑無毛刺，在查看配套0型圈是否正確無誤。3.通過空壓機(jī)氣泵氣管連接閥門，通過電磁換向閥開關(guān)，打開和關(guān)閉閥門，測(cè)試看閥板是否能正常打開和關(guān)閉:如正常打開和關(guān)閉就表示閥門可以正常運(yùn)行。4.檢查完以上幾點(diǎn)，氣動(dòng)高閥可以進(jìn)行設(shè)備安裝了，在安裝前檢查下氣動(dòng)高真空擋板閥的閥腔是否有殘留顆?；蜻z留物。接著對(duì)分子泵接口法蘭和真空設(shè)備接口法蘭這個(gè)法蘭面和通道要清理干凈，包括污垢，油漬，油污殘留等(用酒精和香蕉水粘干凈的抹布擦拭)。5.法蘭面清潔干凈后，法蘭面涂上少里真空脂，接著把0型圈或中心支架放入密封槽內(nèi)，將連接面處兩個(gè)法蘭校正平整無誤，在用螺栓，卡鉗，卡箍等方式進(jìn)行連接固定。真空閥門歸于現(xiàn)場(chǎng)儀表，要求環(huán)境溫度應(yīng)在-25～60℃范圍，相對(duì)濕度≤95%。</p><div
