style="text-indent:25px">上海卓帕真空技術(shù)有限公司**介紹，波紋管截止閥材質(zhì)和閥桿材質(zhì)不同，可焊接性能不同，焊接在一起時容易造成焊接缺點，而導(dǎo)致波紋管容易穿孔。柱失穩(wěn)：指波紋管的波紋連接發(fā)生橫向偏移，使波紋管偏移后的實際軸線成弧形或成s形。波紋管因總厚度不夠，難以抵御試驗壓力或運行壓力，波紋管波數(shù)過多及波紋管同軸度偏差大等都容易產(chǎn)生柱失穩(wěn)。上海卓帕真空技術(shù)有限公司生產(chǎn)的產(chǎn)品普遍用于石油、化工、冶金、機(jī)械、電力、供水等行業(yè)，深受用戶依賴和好評，歡迎大家前來選購產(chǎn)品。</p><p style="text-indent:25px">波紋管易破裂問題：平面失穩(wěn)：表現(xiàn)為一個或幾個波紋平面相對于波紋管軸線發(fā)生轉(zhuǎn)動而傾斜，但波紋管的圓心還基本在波紋管的軸線上。平面失穩(wěn)的原因是由于在內(nèi)壓產(chǎn)生的子午向彎曲應(yīng)力和周向膜應(yīng)力的合力的作用下，波紋管發(fā)生了塑性變形，平面失穩(wěn)多發(fā)生于波紋管處于壓縮狀態(tài)時；柱失穩(wěn)或平面失穩(wěn)得不到控制，波紋形狀發(fā)生較大的變化脫離了原有的計算模型，位移又集中在某一個或某幾個波紋上，將導(dǎo)致波紋管截止閥很快疲勞斷裂。有時雖不至于立即破裂，但它極大降低了波紋管的疲勞壽命和承受壓力的能力。想要了解波紋管閘閥使用注意事項，歡迎咨詢上海卓帕真空技術(shù)有限公司客服人員。</p><div
