我國閥門行業現狀及發展趨勢
發布時間:10/10/2013
        

  中國的閥門業經過幾十年的發展後,已經取得了很大的進步,目前的閥門行業已經能為用戶部門提供大約十二大類,3000多個型号、4000多個規格的産品,其性能參數範圍從真空閥門到600Mpa的超高壓閥門,溫度從深冷-196攝氏度到高溫570攝氏度。使用介質為水、蒸汽、尿素、乙烯、易爆等介質。閥門是利潤率低的産品,市場競争非常激烈。閥門在水處理行業中使用量大,主要以低壓閥門産品為主,如蝶閥、閘閥、止回閥。據了解,目前市場上具有一定規模的閥門企業有2000餘家,大多數分布在江浙及中原一帶。

  目前,國内閥門生産骨幹企業已能按ISO國際标準、DIN德國标準、AWWA美國标準等國際标準設計制造各種閥門,部分廠家的産品達到了國際先進水平。雖然過年閥門行業的整體水平有了較大的提高,但質量上還不夠穩定,如跑、冒、滴、漏現象在國産閥門中經常出現。另外,我國閥門的配套能力也與發達國家相比尚存在一定的差距。如何應對閥門業的市場競争。

  從總體來說,我國閥門市場價格比較平穩,每年雖然略有升降,但幅度都很小。近來,太原、天津對閥門市場進行了檢查,發現許多企業為了赢利以次充好,嚴重的擾亂了閥門市場。

  閥門市場主要存在的問題為:

  一、部分經營者購買無廠名廠址的閥門,打印知名廠家的名牌及合格證,對合格閥門企業的聲譽造成嚴重危害。

  二、翻新閥門,部分經營者通過對廢舊閥門重新油漆後第二次銷售,給工程質量帶來嚴重的安全隐患。

  我國閥門市場的趨勢:

  1、建設正像大型化發展,所以需要大口徑及高壓安全閥和減壓閥,同時也需要快速起閉閥門。

  2、能源發展方面就是節能,從節約能源的角度看要發展蒸汽輸水閥,并向亞臨界和超臨界的高參數發展。

  3、城市建設也要向節能和環保方向過渡,以前一般使用低壓閥門,特别是鐵制低壓閥門,現在向環保型的膠闆閥、平衡閥、金屬密封蝶閥以及中線密封蝶閥過渡,輸油和輸氣工程逐漸向管道化發展,需要更多的平闆閘閥和球閥。

  4、針對成套工程的需要,閥門供應廠商的生産應該向多品種多規格發展。一個工程需要的閥門就可以讓一個廠家滿足已經成為一種趨勢。

  我國的閥門市場已基本形成國營、集體、合資、股份及個體民營并存的局面。一個企業若要在激烈的市場競争中求得穩步發展,可以從一下幾個方面着手。

  1、努力降低生産成本、着眼于提高産品性能和效率。

  2、開發上檔次的高新産品或生産單件小批的非标産品。

  3、通過閥門産品的國際品質認證。

  4、閥門産品應向環保、節能方向發展。

  5、在原有閥門品種基礎上,擴大其他品種及型号的閥門生産
