style="text-indent:25px">上海卓帕真空技術(shù)有限公司**介紹，波紋管截止閥提高了對(duì)出口壓力變化的傳感效能，提高了靈敏度，極大降低了因上游壓力變化，流量變化等因素引起的壓力偏差。改善了流線分布，降低了噪聲。波紋管截止閥適用于公稱壓力PN1．6～16MPa，工作溫度-29～350℃的易燃、易爆、du性流體、高溫導(dǎo)熱油、液氨等介質(zhì)。上海卓帕真空技術(shù)有限公司主要生產(chǎn)鍛鋼閘閥、截止閥、止回閥、球閥、波紋管等。產(chǎn)品采用ISO、API、ANSI、BS、DIN、NF、JIS、JPI、GB、JB等國內(nèi)外先進(jìn)標(biāo)準(zhǔn)生產(chǎn)，產(chǎn)品通徑為3/8“-2”(DN10mm-50mm)，壓力等級(jí)為150Lb-2500Lb(0.1Mpa-42.0Mpa)，工作溫度為-196℃-680℃。閥門主體材料有碳鋼、合金鋼、不銹鋼、蒙乃爾、20號(hào)全金等。并且可以根據(jù)用戶要求進(jìn)行制造。</p><p 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。鋼帶波紋管在墻壁內(nèi)暗裝供水支管時(shí)，有必要根據(jù)設(shè)置計(jì)劃和施工現(xiàn)場(chǎng)的具體環(huán)境，高精度地制作。</p><div
