      • 閥門發展三大瓶頸解析

        閥門發展三大瓶頸解析

              我國閥門市場競爭非常激烈。就閥門市場的分布,主要是依據工程項目的建設,閥門的*大用戶是石化行業、電力部門、冶金部門、核電行業、化工行業和城市建設部門。       我國閥門行業為勞動密集型行業。在中國的出口產品中,勞動密集型產品仍然會在相當長的一段時間里占據主導地位,同時,也應該看到由于各種原因,勞動密集型出口截止閥產品的優勢正在緩慢減弱。中國閥門業要想有長遠的發展,必須調整和優化產業結構,既要繼續充分發揮傳統閥門產業的優勢,又要大力發展知識、技術密集型產業和新興產業,以推動閥門產業的升級。只有這樣,才能盡快縮短中國閥門業與發達國家之間的差距。      目前,我國閥門行業還是以量的擴張為主,形成了在國際市場中同一水平上的過度競爭,要改變這一發展方式,就要堅持創新的理念,在產品開發與技術改造方面創新,可以積極與科研單位、高等院校進行聯合,共同開發新產品項目,努力開拓國內外市場,進而克服數量型增長,提升產品檔次,提高產品的附加值,注重自主品牌建設,以提升我國閥門企業在全球產業分工中的地位,提高抗風險能力與自身的“議價”能力,進而增強閥門行業的可持續發展競爭力。       目前缺乏專業人才已成為制約我國閥門行業進一步發展的瓶頸,這勢必會影響我國減壓閥行業的國際競爭力。要解決這個問題,可以走內部開發和外部引進相結合的道路。一方面,可加強對企業現有員工的短期培訓,以改善現有的人力資源狀況;另一方面,通過各種途徑引進高素質行業人才,提升我國閥門行業的智力資本因素。        中國閥門業要想有長遠的發展,必須調整和優化產業結構,既要繼續充分發揮傳統閥門產業的優勢,又要大力發展知識、技術密集型產業和新興產業,以推動閥門產業的升級。只有這樣,才能盡快縮短中國閥門業與發達國家之間的差距。

        你可知道閥門的歷史?

        閥門的使用觸動著我們生活中的每一天,當我們打開水龍頭喝水或者打開消防栓來澆灌農田的時候,我們和閥門都進行著互動,管道的密集交錯,背后都有著各種閥門的堅守。     閥門的發展與工業生產過程的發展密切相關。遠古時期,人們為了調節河流或小溪的水流量,采用大石塊或樹干來阻止水的流動或改變水的流動方向。早在戰國末年,秦蜀郡太守李冰(生卒年不詳)就已在成都平原開鑿鹽井,汲鹵煎鹽。取鹵時,以細竹作汲鹵筒,插入套管內,筒底以熟皮作啟閉閥門,一筒可汲鹵數斗,井上豎大木架,用轆轤、車盤提取鹵水將竹子桶空在一端裝上木制的柱塞閥防止走漏,子放入井中汲鹵以制鹽。井鹽汲鹵     埃及和希臘文明發明了幾種原始的閥門類型,用于農作物灌溉等。但是,普遍公認是古羅馬人為了農作物灌溉而開發了相當復雜的水系統,采用旋塞閥和柱塞閥,并使用逆止閥防止水的逆流。古羅馬復雜的水利系統     文藝復興時期,在藝術家和發明家達.芬奇設計的溝渠、灌溉項目和其他大型水力系統項目中使用了閥門,他的許多技術方案現在仍實際存在。隨后歐洲因為鍛煉技術和水利機械的發展,對閥門的要求也逐漸提高,所以創造出了銅制和鋁制的旋塞閥,閥門才進入金屬制。達芬奇機械設計手稿     閥門工業的現代歷史與工業革命并行,隨著工業革命的深入而深入。1705年紐康曼發明第一臺工業蒸汽發動機,對蒸汽發動機的運行提出了控制要求。1769年瓦特創造了蒸汽機使閥門正式進入了機械工業領域,蒸汽機上很多采用旋塞閥、安全閥、止回閥和蝶閥。     瓦特發明蒸汽機是閥門工業上大量應用的開始。18世紀到19世紀,蒸汽機在采礦業、鍛煉、紡織、機械制造等行業的迅速推廣,對閥門數量以及質量日益增加,所以呈現了滑閥。他還發明了第一臺調節轉速的控制器,其后,對流體流量的控制越來越被人們重視。而相繼呈現的帶螺紋閥桿的截止閥和帶梯形螺紋閥桿的楔式閘閥,是閥門發展中的一次重大突破。這兩類閥門的呈現不只滿意了其時各個行業對閥門壓力及溫度不斷提高的要求,并且初步滿意了對流量調節的要求。瓦特蒸汽機模型     歷史上第一個閥門原則上應該是球閥或者球形旋塞閥,時間可以追溯到19世紀John.Wallen及John.Charpmen的設計,但當時并沒有投入生產。      第二次世界大戰后,閥門的發展是在政府的促進下完成的,美國海軍是James Bury閥門用于潛艇的早期倡議者。于是圍繞閥門使用的場景,進行了一系列新的研發和嘗試,新的閥門技術也隨著戰火進行了新的革新。軍艦中使用的標準止回閥     由于許多國家進行戰后重建的需要,同時因為各種特殊資料,包含聚合資料、光滑資料、不銹鋼和鈷基硬質合金的開展,陳舊的旋塞閥和蝶閥獲得了新的使用,依據旋塞閥演化的球閥和隔膜閥得到迅速開展。截止閥、閘閥和其他閥門種類添加,質量進步。使得閥門制造業逐步變成機械工業的一個重要部門。工人在檢測成品尺寸     60年代,發達的工業化國家經濟相繼走向繁榮發展時期,前西德、日本、意大利、法國、英國等國家的產品急于尋找國際市場,由成套機械設備出口帶動了閥門出口。     從60年代末到80年代初,舊殖民地國家紛紛獨立,急于發展民族工業而大量進口設備,包括閥門;以及石油危機導致各產油國大力投資于高利潤的石油工業。這一系列原因使國際閥門生產貿易及發展迎來了一個高速增長的時期,進一步推動閥門工業的發展。      我國閥門工業生產的起步較晚。在20世紀60年代開始研制單座閥、雙座閥等產品,主要仿制前蘇聯的產品。由于機械工業落后,機械加工精度低。因此,產品泄漏量較大,但尚能滿足當時工業生產過程的一般控制要求。             70年代開始,隨著工業生產規模的擴大,工業過程控制要求的提高,一些調節閥產品已不能適應生產過程控制的要求,例如對高壓力、高壓降、低溫、高溫和腐蝕介質的控制要求。為此,一些大型石油化工企業在引進設備的同時,也引進一些控制閥,例如帶平衡閥芯的套筒閥、偏心旋轉閥等,為國內的控制閥制造廠商指明了開發方向。因此,70年代后期,一些制造廠已開始仿制偏心旋轉閥等產品。      80年代開始,隨著我國改革開放政策的貫徹和落實,開始組織骨干企業引進國外閥門同類產品的設計、工藝等先進技術和加工設備,使我國的閥門制造技術和產品質量得到了迅速的提高。例如,生產出各種類型的套筒閥、偏心旋轉閥,開始研制精小型調節閥。隨著大型電站等工業項目的進行,也研制了各種電液執行機構、長行程執行機構等執行機構,以適應大推力和大推力矩、長行程等控制要求。      90年代,我國的調節閥工業也在引進和消化國外的先進技術后開始飛速發展,填補了一些特殊工業控制的空白,使我國調節閥工業水平大大提高,縮短了與國外的差距。      目前,國內閥門生產骨干企業已能按ISO國際標準、DIN德國標準、AWWA美國標準等國際標準設計制造各種閥門,部分廠家的產品達到了國際先進水平      雖然過去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、漏現象在國產閥門中經常出現。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。    如果簡要地概述閥門這一工業產品我們可以這么說。閥門是一種在管道運送體系中的控制部件,從*簡略的截止閥到極為復雜的自控體系中所用的各種閥門,包含球閥、蝶閥、閘閥、截止閥、止回閥、調理閥、安全閥、旋塞閥、隔膜閥等。閥門可用于控制空氣,水,蒸汽,各種腐蝕性介質,泥漿,油品,液態金屬和放射性介質等各種類型流體的流動。就閥門市場的分布,主要是依據工程項目的建設,閥門的**用戶是石化行業、電力部門、冶金部門、化工行業和城市建設部門,如城市自來水管道,樓寓建設,城市供熱;輸油管線,制藥行業,食品行業等。閥門在水處理行業中使用量較大,主要以低壓閥門產品為主,如蝶閥、閘閥、止回閥。

      • 史上*全的閘閥分類

        史上*全的閘閥分類

        根據結構形式分,閘閥可分為以下類型:閘閥根據閥桿結構可分為明桿閘閥(升降桿閘閥)和暗桿閘閥(旋轉桿閘閥)。 明桿閘閥(升降桿閘閥):通過旋轉閥桿螺母帶動閥桿升降(不旋轉)來實現閘板啟閉的閘閥。這種結構閘閥對閥桿潤滑有利,閘板開度清楚,閥桿螺紋與閥桿螺母不與介質接觸,不受介質溫度和腐蝕性的影響。示例如下:明桿閘閥示例暗桿閘閥(旋轉桿閘閥):閥桿螺母在閥體內與介質接觸,通過旋轉閥桿來實現閘板啟閉的閘閥。這種結構閘閥,閥門的高度尺寸小,但它的啟閉行程難以控制,需增加指示器,閥桿螺紋及閥桿螺母與介質接觸,要受介質溫度和腐蝕性的影響,因而適用于非腐蝕性介質以及外界環境條件較差的場合。示例如下: 螺紋連接暗桿閘閥示例根據閘板的構造,閘閥可分為平行式閘閥和楔式閘閥。 平行式閘閥:兩個密封面相互平行,且與閥體通道中心線垂直的閘閥。其啟閉件(閘板)可以是單閘板或是帶有撐開機構的雙閘板。平板閘閥流阻小,不縮口的平板閘閥其流阻與短直管相似。帶導流孔的平板閘閥安裝在管路上還可直接用清管器進行清管。同時,由于閘板啟閉時在兩閥座密封面滑動,可適用于帶懸浮顆粒的介質。另外,平板閘閥不會因為閥桿熱伸長而使密封面過載。但平板閘閥存在以下缺點: 當介質壓力較低時,金屬密封面的密封力不足以達到滿意的密封性能; 當介質壓力高時,經常啟閉可能使密封面磨損過大; 閘板在切斷高速和高密度介質時,會產生劇烈振動; d、在圓形流道上橫向運動的圓形閘板只有當它處在閥門關閉位置的50%時,才對流量的控制較敏感。 楔式閘閥:兩個密封面成楔形的閘閥。使用楔形的目的是為了提高輔助密封載荷,實現既能對高的介質壓力密封,也能低的介質壓力密封。楔式閘閥的閥體上設有導向機構(導向筋),可防止閘板在開啟或關閉時旋轉,確保閘板與閥座的密封面相應對準。同時,楔式閘閥在關閉之前不與閥座摩擦,從而減少密封面的磨損。 但楔式閘閥存在以下缺點: 密封面易夾雜流動介質中固體顆粒; 閥桿的熱膨脹可能使密封面產生過載; 閘板不能設置導流孔。 根據JB/T 308閘閥結構形式代號如下:結構形式代號閥桿升降式 (明桿)楔式閘板彈性閘板0剛性閘板單閘板1雙閘板2平行式閘板單閘板3雙閘板4閥桿非升降式(暗桿)楔式閘板單閘板5雙閘板6平行式閘板單閘板7雙閘板8

      • 調壓閥型號怎么選擇呢?

        調壓閥型號怎么選擇呢?

        ? ? ? 為保證氣動自動化系統正常工作,選擇使用調壓閥應考慮以下問題:1)根據要求的工作壓力、調壓范圍和使用流量的*大值及穩壓精度來選擇調壓閥。根據系統的使用工作壓力不同,調壓閥的輸出壓力可分級供給。調壓閥的輸出流量是主要性能參數,一般與閥的接管口徑相對應。若沒有足夠大的大口徑閥供選用,可用幾個調壓閥并聯輸出。但需注意相應的輸入、輸出管道截面積之和不得小于減壓閥公稱通徑截面積之和。穩壓精度要求較高時,應選用先導式減壓閥。2)在易爆有危險的場合,應選用遙控減壓閥(外部先導式)。通常,遙控減壓閥和小型直動式減壓閥配套,將小型減壓閥和壓力表安裝在控制盤上,壓縮空氣經DPC空氣過濾器、DPC減壓閥和DPC油霧器后,供給氣動裝置。3)儲氣罐設置在氣動自動化系統的中間氣動裝置有時為了使工作壓力穩定,常需設置一個儲氣罐。通常這種儲氣罐容積不大,如儲氣罐尺寸為200 X 800(26L),建議儲氣罐就近設置在減壓閥上游回路中,如上圖所示。4)安裝維護調壓閥可在任意位置安裝,但*好能垂直安裝,以便于操作。閥體上的箭頭方向為氣體流動方向,安裝時不能將方向搞錯。需要時,可擰下氣口堵頭,安裝壓力表。安裝前,連接管道應用壓縮空氣將其內灰塵、鐵屑等雜物吹掉。為了延長調壓閥的使用壽命,減壓閥不用時應旋松手柄回零,以免使膜片長期受壓引起塑性變形。在空氣中塵埃較多的地方使用減壓閥,必須在閥前安裝過濾器。調壓閥清洗裝配時,金屬零件應用礦物油洗凈,橡膠件用肥皂液清洗后用水洗凈并吹干。裝配時,滑動部分的表面要涂潤滑脂。膜片、密封圈極易劃傷,裝配時要注意。

      • 調壓閥工作原理是什么?

        調壓閥工作原理是什么?

              調壓閥基本可以說是減壓閥,減壓閥的工作原理如下:高壓介質通過一個小孔充到一個相對較大的腔里實現減壓,實際上是靠截流減壓,膜片或活塞的兩面一面是出口腔,一面是人為給的壓力,并且控制小孔大小的閥桿和膜片(活塞)相連,這樣只要給一個固定的壓力,那么出口腔的壓力就會一直等于這個壓力,這個人為給定的壓力可以由彈簧或氣源或液壓源來提供按用途和作用、主要參數、壓力、介質工作溫度、特殊用途(即特殊、專用閥)、驅動能源、結構等方式進行了分類,其中*常用的分類法是按結構將調節閥分為九個大類,6種為直行程,3種為角行程。

      • 什么是安全閥?

        什么是安全閥?

              全閥是一種安全保護用閥,它的啟閉件受外力作用下處于常閉狀態,當設備或管道內壓力超過安全閥設定壓力時,通過調整閥門中的彈簧力長短,來調節壓緊力,當管路中壓力高于設定值時,彈簧被反向壓迫,油液泄漏流出,從而控制管路中的壓力不會超過某一限定值,保證設備和管道內介質壓力在設定壓力之下,保護設備和管道正常工作,防止發生意外,減少損失。
