    隨著我國經濟的快速發展,閥門業作為一個民族產業,歷經數年風雨,在全國各地得以快速發展,成為國內機械行業發展較快的主要產業之一,我國閥門行業雖發展步伐較快,但出現的問題也較多,行業發展水平低,產品技術含量低,控制閥好多產品還是低檔的多。由于國內閥門行業起步晚,目前還處于發展階段、閥門設計、制造、生產和試驗能力低于國外先進水平,好多關鍵閥門還依賴進口,許多閥門沒有核心技術,加上自動化控制水平的限制,在高端閥門技術方面與發達國家相比有一定差距,出現如此問題究竟原因何在?
      
      在我國目前的閥門市場上,除了低壓閥門已經達到國際市場能接受的水平外,高壓閥門仍然要依靠進口。在宏觀經濟持續看好的形勢下,閥門行業的大部分生產和銷售指標都保持了較快的增長,但是由于價格戰的影響,行業銷售收入和利潤都較去年大幅下降。
      
      隨著世界經濟的回暖,我國閥門產品的進出口也有所增長,但是國際閥門市場的競爭也在不斷加劇。由于在高端技術上與國外的大廠商仍有較大的差距,因此在今后一段時期內,產品技術將成為制約我國閥門產品發展的一個瓶頸。
      
      閥門是石油、化工、電站、長輸管線、造船、核工業、各種低溫工程、宇航以及海洋采油等國民經濟各部門不可缺少的流體控制沒備。據泵閥英才網專家調查發現,經過多年的發展,我國的閥門企業數量居全世界第一,各種大小閥門企業約6000余家,其中年產值超過500萬元的有900家。從產品情況來看,我國閥門行業目前已經能生產十幾大類產品,如閘閥、截止閥、球閥、蝶閥、安全閥、止回閥、節流閥、旋塞閥、減壓閥、隔膜閥、疏水閥、緊急切斷閥等,最高使用溫度達到570℃,最低為-196℃、最高壓力為600Mpa,最大通徑達到5350毫米。
      
      另外,根據相關部門統計,我國每年閥門市場成交額高達500億元左右,其中100多億元的市場卻被國外閥門企業占領。雖然我國閥門行業經過改革開放后的大力發展,已經取得了不小的成績。但目前,我國閥門行業仍然還存在著一些問題,如目前我國閥門企業主要以低層次、小規模、家庭作坊式企業為主。
      
      在產品上,由于重復投資,技術投資、引進不夠,我國閥門企業的主導產品仍然是低質量的大眾產品。目前我國企業生產的各種閥門普遍存在著外漏、內漏、外觀質量不高、壽命短、操作不靈活以及閥門電動裝置和氣動裝置不可靠等缺點,部分產品只相當于上個世紀八十年代初的國際水平。而一些高溫高壓和關鍵裝置上需要的閥門依然依賴進口,另外,我國閥門行業在產業結構、閥門工業的產業鏈,以及行業的專業化程度均同國外企業存在較大的差距。造成國內閥門產品質量低下的原因在于:由于市場急速擴大,而原有國營閥門企業紛紛關停并轉,本來機械工業水平就不高,鄉鎮企業(民營企業)迅速發展起來。但是鄉鎮企業起點低,技術力量非常薄弱,設備簡陋,產品大多數都是模仿生產,特別是給排水用的低壓閥門,問題嚴重。
      
      目前我國閥門行業與國外閥門行業差距較為明顯,主要存在四大綜合性差距:一是技術創新能力上的差距;二是加工工藝上的差距;三是質量管理及設備方面的差距;四是流程管理上的差距。這也讓我們看到自身的不足,以此找到差距與問題實質,從而改進與提高。
