style="text-indent:25px">金屬波紋管的工作溫度范圍為（-253~600）℃。（在高溫下工作的波紋管所使用的材料要有足夠的熱穩(wěn)定性。工作溫度升高，材料的彈性模量下降，從而導致波紋管的剛度、耐壓力和疲勞壽命的降低。在低溫下使用的波紋管材料，需有良好的低溫性能。在低溫下，材料的脆性對表而缺點敏感，因此，對材料的表面質(zhì)量應嚴格控制）。是指沿著軸向剖開后的波紋型式和形狀，波紋管的波紋形狀影響著波紋管的剛度、位移和承壓能力。按幾何形狀波型可分為U型、C型、S型、V型Ω型等。波紋管閘閥只許介質(zhì)單向流動，安裝時有方向性。</p><div

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度和疲勞強度。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，設備精良，工藝先進，全部采用現(xiàn)代化精密數(shù)控機床及各種專業(yè)加工機器進行加工生產(chǎn)，擁有各類加工及檢測設備30多臺，公司通過了ISO9001認證，歡迎大家前來選購產(chǎn)品。波紋管密封截止閥雙重的密封設計（波紋管+填料），若波紋管失效，閥桿填料也會避免；熱鍍鋅波紋管生產(chǎn)</p><p
