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***，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，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?，昆明HDPE雙壁波紋管推薦。波紋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。由于波紋管的伸展要求較大的容積變化，昆明HDPE雙壁波紋管推薦，因此它的響應(yīng)速度低于波登管。波紋管適于測量低壓，昆明HDPE雙壁波紋管推薦。

,做法詳見《給水排水標(biāo)準(zhǔn)圖集》。對一般的土質(zhì)地段，基底可鋪一層厚度為0.1m的粗砂基礎(chǔ);對軟土地基，且槽底處在地下水位以下時，宜鋪墊厚度不小于0.2m的沙礫基礎(chǔ),亦可分兩層鋪設(shè)，下層用粒徑5~40mm的碎石，上層鋪粗沙，厚度不小于0.05m。 </p> <p> (2)管道基礎(chǔ)在接口部位的凹槽,宜在鋪設(shè)管道時隨鋪隨挖,凹槽長度按管道管徑大小采用,宜為0.4-0.6m,凹槽深度易為0.05-0.1m,凹槽寬度宜為管外徑的1.1倍，在接口完成后，凹槽隨即用砂回填密實。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

PVC雙壁波紋管與PE雙壁波紋管施工方法相同。 </p> <p> （1）橡膠圈安裝位置應(yīng)在插口第二與第三波紋之間槽內(nèi)，安裝密封圈的數(shù)量視設(shè)計要求而定，當(dāng)采用兩只密封圈時建議兩密封圈之間隔一個波紋； </p> <p> （2）接口前應(yīng)先將承口插口內(nèi)外表面清理干凈，在插口套入密封圈，并在承口內(nèi)工作面和橡膠圈表面涂上潤滑劑（一般用肥皂水即可），插入方向為水流方向，對準(zhǔn)承口中心線用人力或設(shè)置木擋板用撬棍將被安裝的管材徐徐插入承口內(nèi)直至底部； </p> <p> （3）接口完成后，隨即用相同土質(zhì)把預(yù)留凹槽處填筑密實； </p> <p> （4）管道應(yīng)直線敷設(shè)，相鄰兩節(jié)管道軸線的允許轉(zhuǎn)角一般不得大于2度。 </p> <p> 五、用途范圍 </p> <p> 除兩種管材共用的領(lǐng)域如市政工程、小區(qū)地下排水排污工程、高速公路工程、農(nóng)田水利灌溉工程外，PE雙壁波紋管還可應(yīng)用于化工礦山流體輸送工程，范圍相對更廣。 </p> </p><div
