概述:閥門行業在國民經濟發展中,作為準備制造業的一個重要環節,起到非常重要的作用。由于我國國內閥門制造業水平與國際先進水平相比仍有一定差距,好多高參數、高溫高壓、高磅級的關鍵閥門原一直依賴進口,為了力促閥門國產化,在國務院下達的《關于加快振興裝備制造業的若干意見》后,國家有關部門根據國家作出的重大裝備國產化的要求,先后作出了一系列重大部署,并由國家發改委牽頭,中國機械工業聯合會和中國通用機械工業協會一起,部署制訂了相關領域重大裝備的閥門國產化方案,并多次與有關部門協調,如今閥門國產化在國內閥門行業已形成共識,經過20年來特別是近幾年的科研、設計、制造和用戶相結合的共同努力,聯合攻關,已卓有成效。在“西氣東輸”“南水北調”、“三峽水利樞紐”百萬千瓦核電機組、百萬噸乙烯改造工程、超臨界和超超臨界火電機組、油氣管道輸送、煤化工、大型船舶、城市污水處理等重大工程裝備項目和核電、石化、冶金,電站等領域上,除少量高參數安全閥和調節閥需進口外,實現了閥門國產化,從而改變了重大裝備關鍵閥門長久受制于國外的局面。并爭取在短期內盡可能重大工程項目和關鍵閥門實現國產化,或部分實現國產化,使我國閥門制造業走在世界前列。

從零開始加快閥門國產化步伐

我國閥門國產化當初是一無所有的,從零開始,并從核電站和核化工、以及石化設備上開始立足國產化,在 80 年代攻下了第一臺 60 萬核電機組有關工程上關鍵項目,后來在搞秦山核電站時,寧波閥門廠作為核工程管件閥門的國產化試點企業,為閥門國產化作出了貢獻。改革開放后我國加大閥門國產化的力度,隨著閥門行業制造工藝水平不斷提高,許多企業采用了先進的樹脂砂脫箱造型線生產鑄件毛坯,鑄件化學成份采用直讀光譜儀進行快速分析,采用鈷 60γ 射線對鑄件進行缺陷探測;鍛造采用胎模鍛和多向模鍛等先進工藝。在進入 21 世紀后,閥門國產化步伐加快,在有關重大工程項目國產化有了業績。

國內骨干企業積極行動,主動克服困難,為國分憂,挑起研發與制造的核閥國產化重擔。以中核蘇閥、沈陽盛世、大連大高等一批老企業,取得了設計生產核閥的資格,在我國核閥國產化過程中取得成果。目前,國內已有 19 個企業獲得了國家核安全局頒發的民用核承壓設備設計和生產資格許可證,可設計和生產核閥。其設計、生產閥門的種類有閘閥截止閥調節閥等。這 19 個企業中具備設計生產核Ⅰ級閥門的企業有 5 家(中核蘇閥、沈高、大高、上閥、上海良工)。目前,國內已成功研發了壓水堆核島核Ⅰ級電動閘閥、止回閥、電動波紋管截止閥、快中子增殖反應堆用核Ⅱ級電動波紋管鈉截止閥等具有較高水平的核閥。
