波紋管是指用可折疊皺紋片沿折疊伸縮方向連接成的管狀彈性敏感元件。波紋管在儀器儀表中應(yīng)用大面積，主要用途是作為壓力測量儀表的測量元件，將壓力轉(zhuǎn)換成位移或力。波紋管管壁較薄，靈敏度較高，測量范圍為數(shù)十帕至數(shù)十兆帕。它的開口端固定，密封端處于自由狀態(tài)，并利用輔助的螺旋彈簧或簧片增加彈性。工作時在內(nèi)部壓力的作用下沿管子長度方向伸長，遂寧聚乙烯波紋管批發(fā)，使活動端產(chǎn)生與壓力成一定關(guān)系的位移?；顒佣藥又羔樇纯芍苯又甘緣毫Φ拇笮　２y管常常與位移傳感器組合起來構(gòu)成輸出為電量的壓力傳感器，有時也用作隔離元件，遂寧聚乙烯波紋管批發(fā)。由于波紋管的伸展要求較大的容積變化，遂寧聚乙烯波紋管批發(fā)，因此它的響應(yīng)速度低于波登管。波紋管適于測量低壓。

金屬波紋管及翅片式波紋管在內(nèi)燃機(jī)冷卻器中的應(yīng)用，在汽柴油發(fā)動機(jī)冷卻器殼體內(nèi)或冷卻芯子的兩管板間安裝1－1000根帶有間斷性凸凹狀金屬波紋管，采用擴(kuò)管法、焊接法等方法將其固定在一端管板上，使冷卻介質(zhì)的流動狀態(tài)發(fā)生改變，達(dá)到提高傳熱系數(shù)，增加傳熱效率。該發(fā)明構(gòu)思新奇、工藝實(shí)用、成本低廉、性能可靠、傳熱效率高、不結(jié)垢、壽命長、熱應(yīng)力小。1、壓力根據(jù)軟管實(shí)際工作壓力，再查詢波紋的公稱通徑與壓力表,決定是否使用不銹鋼網(wǎng)套類型的。2、尺寸軟管公稱通徑，選用接頭型式（主要有法蘭聯(lián)接、螺紋連接、快速接頭連接）及的尺寸，軟管長度。

金屬波紋管設(shè)計(jì)的理論基礎(chǔ)是板殼理論、材料力學(xué)、計(jì)算數(shù)學(xué)等。波紋管設(shè)計(jì)的參數(shù)較多，由于波紋管在系統(tǒng)中的用途不同，其設(shè)計(jì)計(jì)算的重點(diǎn)也不一樣。例如，波紋管用于力平衡元件，要求波紋管在工作范圍內(nèi)其有效面積不變或變化很小，用于測量元件，要求波紋管的彈性特性是線性的；用于真空開關(guān)管作真空密封件，要求波紋管的真空密封性、軸向位移量和疲勞壽命；用于閥門作密封件，要求波紋管應(yīng)具有一定的耐壓力、耐腐蝕、耐溫度、工作位移和疲勞壽命。根據(jù)波紋管的結(jié)構(gòu)特點(diǎn)，可以把波紋管當(dāng)作圓環(huán)殼、扁錐殼或圓環(huán)板所組成。設(shè)計(jì)計(jì)算波紋管也就是設(shè)計(jì)計(jì)算圓外殼、扁錐殼或團(tuán)環(huán)板。計(jì)算的參數(shù)為剛度、應(yīng)力、有效面積、失穩(wěn)、允許位移、耐壓力和使用壽命。
