一、中國閥門行業發展回顧

我國的閥門行業發展已有幾十年歷史。閥門廠家也由小變大,在研制、開發、生產等各方面都在不斷進步。在上世紀八十年代以前只能生產 600 多個品種系列,2700 多個規格。上世紀末以來,閥門行業有了較大發展,已能生產:閘閥截止閥、節流閥、球閥蝶閥、隔膜閥、旋塞閥止回閥、安全閥、減壓閥疏水閥和其它閥門共 12 大類,3000 多個型號,40000 多個規格的閥門產品。最高使用壓力為 600MPa,最高使用溫度為 650℃(本體)、1200℃(耐火材料襯里),最低使用溫度為 -196℃,最大公稱通徑達到 535Omm。主要市場集中在大型輸油管道市場、核電及其核化工市場、石油石化市場、水務閥門市場、電力市場、煤化工市場以及冶金、化工、造紙、醫藥等市場領域。
