style="text-indent:25px">波紋管閥是什么？上海卓帕真空技術(shù)有限公司**介紹，波紋管閥的英文名稱是bellowsvalve，是用波紋管作為閥桿密封元件的閥門。波紋管閥常用于對閥桿密封要求嚴(yán)格的場合，如用于高真空的場合和核工業(yè)中。采用波紋管代替普通閥門上的填料函或與填料函并用，可使閥桿部位無泄漏，以防止放射性物質(zhì)或貴重物質(zhì)外漏，或保持高真空。波紋管閥的比較高工作壓力取決于波紋管的耐壓強(qiáng)度和疲勞強(qiáng)度。波紋管閥隨閥桿的升降而伸縮。上海卓帕真空技術(shù)有限公司座落于浙江溫州永嘉甌北，是一家集科研，生產(chǎn)及銷售鍛鋼閥門的專業(yè)生產(chǎn)產(chǎn)家。公司技術(shù)力量雄厚，設(shè)備精良，工藝先進(jìn)，全部采用現(xiàn)代化精密數(shù)控機(jī)床及各種專業(yè)加工機(jī)器進(jìn)行加工生產(chǎn)，擁有各類加工及檢測設(shè)備30多臺，公司通過了ISO9001認(rèn)證，歡迎大家前來選購產(chǎn)品。想要知道波紋管截止閥的損壞原因，歡迎咨詢上海卓帕真空技術(shù)有限公司專業(yè)人員。</p><div
