style="text-indent:25px">常用真空閥門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。真空閥門的主要性能參數(shù)是導(dǎo)通率、漏氣率、開關(guān)動(dòng)作的可靠性和準(zhǔn)確性，以及閥門的開閉時(shí)間。閥門按照驅(qū)動(dòng)形式分為手動(dòng)和自動(dòng)兩種。自動(dòng)閥門以壓縮空氣驅(qū)動(dòng)為主，一部分小型閥門通過電磁鐵來驅(qū)動(dòng)。真空系統(tǒng)中常用的閥門大體有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。各種真空閥門根據(jù)應(yīng)用的真空領(lǐng)域和使用目的而選定。</p><p

style="text-indent:25px">如何正確地選用各種真空閥門？蝶閥的介紹及選型：蝶閥的蝶板安裝于管道的直徑方向。在蝶閥閥體圓柱形通道內(nèi)，圓盤形蝶板繞著軸線旋轉(zhuǎn)，旋轉(zhuǎn)角度為0°~90°之間，旋轉(zhuǎn)到90°時(shí)，閥門則牌全開狀態(tài)。蝶閥結(jié)構(gòu)簡(jiǎn)單、體積小、重量輕，只由少數(shù)幾個(gè)零件組成。而且只需旋轉(zhuǎn)90°即可快速啟閉，操作簡(jiǎn)單，同時(shí)該閥門具有良好的流體控制特性。蝶閥處于完全開啟位置時(shí)，蝶板厚度是介質(zhì)流經(jīng)閥體時(shí)的阻力，因此通過該閥門所產(chǎn)生的壓力降很小，故具有較好的流量控制特性。蝶閥有彈密封和金屬的密封兩種密封型式。彈性密封閥門，密封圈可以鑲嵌在閥體上或附在蝶板周邊。石家莊滑閥真空泵</p><p
