style="text-indent:25px">波紋管截止閥這一點(diǎn)就比普通的好，普通截止閥用填料密封，閥桿和填料間會(huì)滑動(dòng)，在低溫下容易泄露。波紋管截止閥內(nèi)部采用波紋管結(jié)構(gòu)，不銹鋼的波紋管下端焊接在閥桿上，以防止工藝流體浸蝕閥桿，另一端置于閥體和閥蓋之間構(gòu)成靜密封。采用雙重的密封設(shè)計(jì)若波紋管失效閥桿填料也會(huì)避免泄漏，波紋管焊于閥桿保持穩(wěn)定的運(yùn)行性能，避免由于閥塞振動(dòng)引起閥桿振動(dòng)。波紋管截止閥是個(gè)比較小的類別，蒸汽截止閥的類別相對(duì)比較大，普通的截止閥也可以用在蒸汽系統(tǒng)上。批發(fā)波紋管波紋管閘閥的結(jié)構(gòu)長(zhǎng)度大于閘閥，同時(shí)流體阻力大，長(zhǎng)期運(yùn)行時(shí)，密封可靠性不強(qiáng)。</p><div

style="text-indent:25px">波紋管易破裂問(wèn)題：平面失穩(wěn)：表現(xiàn)為一個(gè)或幾個(gè)波紋平面相對(duì)于波紋管軸線發(fā)生轉(zhuǎn)動(dòng)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(shí)；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(jì)算模型，位移又集中在某一個(gè)或某幾個(gè)波紋上，將導(dǎo)致波紋管截止閥很快疲勞斷裂。有時(shí)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。波紋管閘閥分為三類：直通式、直角式及直流式斜截止閥。</p><div
