valve)問世于20世紀50年代，隨著科學技術的飛速發(fā)展，生產(chǎn)工藝及產(chǎn)品結構的不斷改進，在短短的40年時間里，已迅速發(fā)展成為一種主要的閥類。在西方工業(yè)發(fā)達的國家，球閥的使用正在逐年不斷的上升。</p><p style="text-indent:25px">球閥按結構形式可分：通常在與球體的上、下軸上裝有軸承，操作扭距小，適用于高壓和大口徑的閥門。為了減少球閥的操作扭矩和增加密封的可靠程度，出現(xiàn)了油封球閥，既在密封面間壓注特制的潤滑油，以形成一層油膜，即增強了密封性，又減少了操作扭矩，更適用高壓大口徑的球閥。彈性式球閥:球閥的球體是彈性的。球體和閥座密封圈都采用金屬材料制造，密封比壓很大，依靠介質本身的壓力已達不到密封的要求，必須施加外力。這種閥門適用于高溫高壓介質。球閥可以普遍應用于化工和食品行業(yè)。</p><div
