style="text-indent:25px">氣動高真空球閥作為一種高真空、氣體密性控制閥門，它通過電磁換向閥控制打開關閉、采用活套法蘭、快卸法蘭、螺紋、悍接四鐘不同方式連接。閥體結構為直通式，可在低真空和高真空與低壓的狀態(tài)下使用。高真空球閥可以實現(xiàn)開關氣路，進而改變氣流的流通路線。當高真空球閥的閥門1號與4號關閉、閥門2號開啟時，機械真空泵將開始對真空系統(tǒng)進行真空抽氣，氣流通過管道逐漸抽空:此時，閥門2號關閉，閥門4號開啟，機械泵對擴散泵進行真空抽氣:當閥門1號與4號再次同時打開時，擴散泵與機械泵將同時開始對容器進行抽真空工作。高真空球閥可以改變氣流的大小。閥門1號的開啟角度可以調節(jié)流經(jīng)管道的氣流重大小:當控制者關閉閥門2號與4號時，通過閥門3號給機械泵放氣，并且通過閥門5號高真空球閥來實施容里調節(jié)真空度。</p><p style="text-indent:25px">如何正確地選用各種真空閥門？真空閥門種類的不同，適用的場合也不同，下面就閘閥、截止閥、蝶閥、球閥等不同種類的閥門，講敘閥門的特性及常用區(qū)域。還根據(jù)使用要求的不同如何選擇閥門，比如按照按防止介質倒流選用閥門、按調節(jié)介質參數(shù)選用閥門。閘閥的介紹及選型：閘閥是作為截止介質使用，在全開時整個流通直通，此時介質運行的壓力損失比較小。閘閥通常適用于不需要經(jīng)常啟閉，而且保持閘板全開或全閉的工況。不適用于作為調節(jié)或節(jié)流使用。對于高速流動的介質，閘板在局部開啟狀況下可以引起閘門的振動，而振動又可能損傷閘板和閥座的密封面，而節(jié)流會使閘板遭受介質的沖蝕。從結構形式上，主要的區(qū)別是所采用的密封元件的形式。根據(jù)密封元件的形式，常常把閘閥分成幾種不同的類型，如：楔式閘閥、平行式閘閥、平行雙閘板閘閥、楔式雙閘板閘等。比較常用的形式是楔式閘閥和平行式閘閥。真空擋板閥用于接通或切斷真空管路中的氣流，適用介質為空氣及非腐蝕性氣體。</p><div
