style="text-indent:25px">上海卓帕真空技術(shù)有限公司**介紹，波紋管截止閥大口徑截止閥的關(guān)閉難及密封面易損壞的問題：一般大管徑管線開啟時，都需要對管線進行預(yù)熱，而預(yù)熱過程一般要求很小流量蒸汽通過，使管線緩慢均勻加熱到一定程度后，才能完全開啟截止閥，避免造成管線急速升溫而產(chǎn)生過度膨脹，損壞部分連接部位。但在這過程中，閥門開度往往非常小，從而造成沖蝕率遠遠大于正常使用效果，嚴重降低閥門密封面的使用壽命。上海卓帕真空技術(shù)有限公司生產(chǎn)的產(chǎn)品普遍用于石油、化工、冶金、機械、電力、供水等行業(yè)，深受用戶依賴和好評，歡迎大家前來選購產(chǎn)品。</p><p
