D634-371C?R24K02MONSS2????為了保證閥門的密封性能，要求閥板壓緊密封圈時能自動均壓;當大氣壓壓到閥板上時能允許進一步壓緊;又因為密封圈和其它傳動件的加工制造差不可避免，所以閥板壓緊程度必須可調(diào)。這就是壓緊裝置的均壓、續(xù)壓和調(diào)壓問題。在圖11所示的真空閥門中，通過錐面閥座和與之配合的錐面閥板及鉸銷壓緊來自動調(diào)均對膠墊的壓力;利用壓桿頭(兼作導向桿8)與閥板螺紋聯(lián)接來達到壓緊程度可調(diào);利用初壓后活塞達不到氣缸底來實現(xiàn)大氣壓壓到閥板時，閥板繼續(xù)壓緊密封圈。4WEH16J70/6EG24N9K4/B08P4.5

??上述的均壓措施在鉸銷軸方向不能自動均壓，需要在裝配中人工調(diào)好。對于口徑較小的閥門，由于絕對誤差量較小，在裝配中容易調(diào)好，但對于口徑較大的閥門，就困難得多。因此對于大口徑閥門應采用完全自動均壓的措施。例如圖28所示的結(jié)構(gòu)，采用球而壓頭就能完全自動均壓。DGMR1-3-PP-AW-B-40

??(4)閥板的傳動機構(gòu)

????對于真空翻板閥，閥門開啟時閥板翻轉(zhuǎn)一個角度，對閥板運動的特殊要求是：①閥板壓緊或松開密封墊圈時，需要直起直落;②開啟閥板時，需要翻轉(zhuǎn)較大的角度，最好達到90°;③在閥板翻轉(zhuǎn)過程中，閥板不能與閥座相碰。目前國內(nèi)主要采用三種翻轉(zhuǎn)機構(gòu)，即擋桿擋翻、四連桿機構(gòu)和蚌線機構(gòu)。

????真空閥門的傳動動力主要有手動、磁動、氣動、電動和液動。選擇閥門動力主要考慮①操作方便;②工作可靠。例如手動適合于小型的，自動化程度要求不高的和試驗用的設(shè)備上應用的閥門;而大型工業(yè)生產(chǎn)用的自動化程度高的設(shè)備上的閥門，則必須用磁動、氣動、電動或液壓的。一般說來，磁動閥門口徑都較小，RZMO-A-030/100/18
