style="text-indent:25px">彈性節(jié)（脹節(jié)操）首要用于補償管道因溫度改變而發(fā)作的彈性變形，也用于管道因設(shè)備調(diào)整等需求的長度補償，首要分為彎管式脹節(jié)操、波紋管脹節(jié)操和套管彈性節(jié) 3種結(jié)構(gòu)辦法。彎管式脹節(jié)操將管子彎成U形或其他形體（圖1[彎管式脹節(jié)操]），北京伸縮節(jié)直銷，并運用形體的彈性變形才能進行補償?shù)囊环N脹節(jié)操。它的利益是強度好、壽數(shù)長、可在現(xiàn)場制造，北京伸縮節(jié)直銷,缺點是占用空間大、消耗鋼材多和摩擦阻力大這種脹節(jié)操廣（guang）泛用于各種蒸汽管道和長管道上。波紋管脹節(jié)操用金屬波紋管制成的一種脹節(jié)操。它能沿軸線方向彈性，北京伸縮節(jié)直銷，也容許少數(shù)曲折。圖2[波紋管脹節(jié)操]為常見的軸向式波紋管脹節(jié)操，用在管道上進行軸向長度補償。</p><div

style="text-indent:25px">套管彈性節(jié)由可以作軸向相對運動的表里套管組成。表里套管之間采用填料函密封。使用時堅持兩頭管子在一條軸線上移動。在彈性節(jié)的兩頭裝設(shè)導(dǎo)向支架。它的長處是對流體的活動摩擦阻力小，結(jié)構(gòu)緊湊；缺點是密封性較差，對固定支架推力較大。套管彈性節(jié)主要用于水管道和低壓蒸汽管道。合理的設(shè)計管路體系中的支座，是確保波紋管彈性節(jié)正常發(fā)揮作用的條件，不同類型的波紋管彈性節(jié)，關(guān)于管系的支座有不同的要求。主固定支座是安裝在具有一個或者幾個無約束波紋管彈性節(jié)的管系上，它接受由與它相連接的每一管段上所施加在它上面的力和力矩。</p><div
