  • 閥門發(fā)展三大瓶頸解析

    閥門發(fā)展三大瓶頸解析

          我國閥門市場(chǎng)競(jìng)爭非常激烈。就閥門市場(chǎng)的分布,主要是依據(jù)工程項(xiàng)目的建設(shè),閥門的*大用戶是石化行業(yè)、電力部門、冶金部門、核電行業(yè)、化工行業(yè)和城市建設(shè)部門。       我國閥門行業(yè)為勞動(dòng)密集型行業(yè)。在中國的出口產(chǎn)品中,勞動(dòng)密集型產(chǎn)品仍然會(huì)在相當(dāng)長的一段時(shí)間里占據(jù)主導(dǎo)地位,同時(shí),也應(yīng)該看到由于各種原因,勞動(dòng)密集型出口截止閥產(chǎn)品的優(yōu)勢(shì)正在緩慢減弱。中國閥門業(yè)要想有長遠(yuǎn)的發(fā)展,必須調(diào)整和優(yōu)化產(chǎn)業(yè)結(jié)構(gòu),既要繼續(xù)充分發(fā)揮傳統(tǒng)閥門產(chǎn)業(yè)的優(yōu)勢(shì),又要大力發(fā)展知識(shí)、技術(shù)密集型產(chǎn)業(yè)和新興產(chǎn)業(yè),以推動(dòng)閥門產(chǎn)業(yè)的升級(jí)。只有這樣,才能盡快縮短中國閥門業(yè)與發(fā)達(dá)國家之間的差距。      目前,我國閥門行業(yè)還是以量的擴(kuò)張為主,形成了在國際市場(chǎng)中同一水平上的過度競(jìng)爭,要改變這一發(fā)展方式,就要堅(jiān)持創(chuàng)新的理念,在產(chǎn)品開發(fā)與技術(shù)改造方面創(chuàng)新,可以積極與科研單位、高等院校進(jìn)行聯(lián)合,共同開發(fā)新產(chǎn)品項(xiàng)目,努力開拓國內(nèi)外市場(chǎng),進(jìn)而克服數(shù)量型增長,提升產(chǎn)品檔次,提高產(chǎn)品的附加值,注重自主品牌建設(shè),以提升我國閥門企業(yè)在全球產(chǎn)業(yè)分工中的地位,提高抗風(fēng)險(xiǎn)能力與自身的“議價(jià)”能力,進(jìn)而增強(qiáng)閥門行業(yè)的可持續(xù)發(fā)展競(jìng)爭力。       目前缺乏專業(yè)人才已成為制約我國閥門行業(yè)進(jìn)一步發(fā)展的瓶頸,這勢(shì)必會(huì)影響我國減壓閥行業(yè)的國際競(jìng)爭力。要解決這個(gè)問題,可以走內(nèi)部開發(fā)和外部引進(jìn)相結(jié)合的道路。一方面,可加強(qiáng)對(duì)企業(yè)現(xiàn)有員工的短期培訓(xùn),以改善現(xiàn)有的人力資源狀況;另一方面,通過各種途徑引進(jìn)高素質(zhì)行業(yè)人才,提升我國閥門行業(yè)的智力資本因素。        中國閥門業(yè)要想有長遠(yuǎn)的發(fā)展,必須調(diào)整和優(yōu)化產(chǎn)業(yè)結(jié)構(gòu),既要繼續(xù)充分發(fā)揮傳統(tǒng)閥門產(chǎn)業(yè)的優(yōu)勢(shì),又要大力發(fā)展知識(shí)、技術(shù)密集型產(chǎn)業(yè)和新興產(chǎn)業(yè),以推動(dòng)閥門產(chǎn)業(yè)的升級(jí)。只有這樣,才能盡快縮短中國閥門業(yè)與發(fā)達(dá)國家之間的差距。

  • 你可知道閥門的歷史?

    你可知道閥門的歷史?

    閥門的使用觸動(dòng)著我們生活中的每一天,當(dāng)我們打開水龍頭喝水或者打開消防栓來澆灌農(nóng)田的時(shí)候,我們和閥門都進(jìn)行著互動(dòng),管道的密集交錯(cuò),背后都有著各種閥門的堅(jiān)守。     閥門的發(fā)展與工業(yè)生產(chǎn)過程的發(fā)展密切相關(guān)。遠(yuǎn)古時(shí)期,人們?yōu)榱苏{(diào)節(jié)河流或小溪的水流量,采用大石塊或樹干來阻止水的流動(dòng)或改變水的流動(dòng)方向。早在戰(zhàn)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(shí),以細(xì)竹作汲鹵筒,插入套管內(nèi),筒底以熟皮作啟閉閥門,一筒可汲鹵數(shù)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(fā)明了幾種原始的閥門類型,用于農(nóng)作物灌溉等。但是,普遍公認(rèn)是古羅馬人為了農(nóng)作物灌溉而開發(fā)了相當(dāng)復(fù)雜的水系統(tǒng),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(fù)雜的水利系統(tǒng)     文藝復(fù)興時(shí)期,在藝術(shù)家和發(fā)明家達(dá).芬奇設(shè)計(jì)的溝渠、灌溉項(xiàng)目和其他大型水力系統(tǒng)項(xiàng)目中使用了閥門,他的許多技術(shù)方案現(xiàn)在仍實(shí)際存在。隨后歐洲因?yàn)殄憻捈夹g(shù)和水利機(jī)械的發(fā)展,對(duì)閥門的要求也逐漸提高,所以創(chuàng)造出了銅制和鋁制的旋塞閥,閥門才進(jìn)入金屬制。達(dá)芬奇機(jī)械設(shè)計(jì)手稿     閥門工業(yè)的現(xiàn)代歷史與工業(yè)革命并行,隨著工業(yè)革命的深入而深入。1705年紐康曼發(fā)明第一臺(tái)工業(yè)蒸汽發(fā)動(dòng)機(jī),對(duì)蒸汽發(fā)動(dòng)機(jī)的運(yùn)行提出了控制要求。1769年瓦特創(chuàng)造了蒸汽機(jī)使閥門正式進(jìn)入了機(jī)械工業(yè)領(lǐng)域,蒸汽機(jī)上很多采用旋塞閥、安全閥、止回閥和蝶閥。     瓦特發(fā)明蒸汽機(jī)是閥門工業(yè)上大量應(yīng)用的開始。18世紀(jì)到19世紀(jì),蒸汽機(jī)在采礦業(yè)、鍛煉、紡織、機(jī)械制造等行業(yè)的迅速推廣,對(duì)閥門數(shù)量以及質(zhì)量日益增加,所以呈現(xiàn)了滑閥。他還發(fā)明了第一臺(tái)調(diào)節(jié)轉(zhuǎn)速的控制器,其后,對(duì)流體流量的控制越來越被人們重視。而相繼呈現(xiàn)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(fā)展中的一次重大突破。這兩類閥門的呈現(xiàn)不只滿意了其時(shí)各個(gè)行業(yè)對(duì)閥門壓力及溫度不斷提高的要求,并且初步滿意了對(duì)流量調(diào)節(jié)的要求。瓦特蒸汽機(jī)模型     歷史上第一個(gè)閥門原則上應(yīng)該是球閥或者球形旋塞閥,時(shí)間可以追溯到19世紀(jì)John.Wallen及John.Charpmen的設(shè)計(jì),但當(dāng)時(shí)并沒有投入生產(chǎn)。      第二次世界大戰(zhàn)后,閥門的發(fā)展是在政府的促進(jìn)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(chǎng)景,進(jìn)行了一系列新的研發(fā)和嘗試,新的閥門技術(shù)也隨著戰(zhàn)火進(jìn)行了新的革新。軍艦中使用的標(biāo)準(zhǔn)止回閥     由于許多國家進(jìn)行戰(zhàn)后重建的需要,同時(shí)因?yàn)楦鞣N特殊資料,包含聚合資料、光滑資料、不銹鋼和鈷基硬質(zhì)合金的開展,陳舊的旋塞閥和蝶閥獲得了新的使用,依據(jù)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(zhì)量進(jìn)步。使得閥門制造業(yè)逐步變成機(jī)械工業(yè)的一個(gè)重要部門。工人在檢測(cè)成品尺寸     60年代,發(fā)達(dá)的工業(yè)化國家經(jīng)濟(jì)相繼走向繁榮發(fā)展時(shí)期,前西德、日本、意大利、法國、英國等國家的產(chǎn)品急于尋找國際市場(chǎng),由成套機(jī)械設(shè)備出口帶動(dòng)了閥門出口。     從60年代末到80年代初,舊殖民地國家紛紛獨(dú)立,急于發(fā)展民族工業(yè)而大量進(jìn)口設(shè)備,包括閥門;以及石油危機(jī)導(dǎo)致各產(chǎn)油國大力投資于高利潤的石油工業(yè)。這一系列原因使國際閥門生產(chǎn)貿(mào)易及發(fā)展迎來了一個(gè)高速增長的時(shí)期,進(jìn)一步推動(dòng)閥門工業(yè)的發(fā)展。      我國閥門工業(yè)生產(chǎn)的起步較晚。在20世紀(jì)60年代開始研制單座閥、雙座閥等產(chǎn)品,主要仿制前蘇聯(lián)的產(chǎn)品。由于機(jī)械工業(yè)落后,機(jī)械加工精度低。因此,產(chǎn)品泄漏量較大,但尚能滿足當(dāng)時(shí)工業(yè)生產(chǎn)過程的一般控制要求。             70年代開始,隨著工業(yè)生產(chǎn)規(guī)模的擴(kuò)大,工業(yè)過程控制要求的提高,一些調(diào)節(jié)閥產(chǎn)品已不能適應(yīng)生產(chǎn)過程控制的要求,例如對(duì)高壓力、高壓降、低溫、高溫和腐蝕介質(zhì)的控制要求。為此,一些大型石油化工企業(yè)在引進(jìn)設(shè)備的同時(shí),也引進(jìn)一些控制閥,例如帶平衡閥芯的套筒閥、偏心旋轉(zhuǎn)閥等,為國內(nèi)的控制閥制造廠商指明了開發(fā)方向。因此,70年代后期,一些制造廠已開始仿制偏心旋轉(zhuǎn)閥等產(chǎn)品。      80年代開始,隨著我國改革開放政策的貫徹和落實(shí),開始組織骨干企業(yè)引進(jìn)國外閥門同類產(chǎn)品的設(shè)計(jì)、工藝等先進(jìn)技術(shù)和加工設(shè)備,使我國的閥門制造技術(shù)和產(chǎn)品質(zhì)量得到了迅速的提高。例如,生產(chǎn)出各種類型的套筒閥、偏心旋轉(zhuǎn)閥,開始研制精小型調(diào)節(jié)閥。隨著大型電站等工業(yè)項(xiàng)目的進(jìn)行,也研制了各種電液執(zhí)行機(jī)構(gòu)、長行程執(zhí)行機(jī)構(gòu)等執(zhí)行機(jī)構(gòu),以適應(yīng)大推力和大推力矩、長行程等控制要求。      90年代,我國的調(diào)節(jié)閥工業(yè)也在引進(jìn)和消化國外的先進(jìn)技術(shù)后開始飛速發(fā)展,填補(bǔ)了一些特殊工業(yè)控制的空白,使我國調(diào)節(jié)閥工業(yè)水平大大提高,縮短了與國外的差距。      目前,國內(nèi)閥門生產(chǎn)骨干企業(yè)已能按ISO國際標(biāo)準(zhǔn)、DIN德國標(biāo)準(zhǔn)、AWWA美國標(biāo)準(zhǔn)等國際標(biāo)準(zhǔn)設(shè)計(jì)制造各種閥門,部分廠家的產(chǎn)品達(dá)到了國際先進(jìn)水平      雖然過去閥門行業(yè)的整體水平有了較大的提高,但質(zhì)量上還不夠穩(wěn)定,如跑、冒、滴、漏現(xiàn)象在國產(chǎn)閥門中經(jīng)常出現(xiàn)。另外,我國閥門的配套能力也與發(fā)達(dá)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(yè)產(chǎn)品我們可以這么說。閥門是一種在管道運(yùn)送體系中的控制部件,從*簡略的截止閥到極為復(fù)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(diào)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(zhì),泥漿,油品,液態(tài)金屬和放射性介質(zhì)等各種類型流體的流動(dòng)。就閥門市場(chǎng)的分布,主要是依據(jù)工程項(xiàng)目的建設(shè),閥門的**用戶是石化行業(yè)、電力部門、冶金部門、化工行業(yè)和城市建設(shè)部門,如城市自來水管道,樓寓建設(shè),城市供熱;輸油管線,制藥行業(yè),食品行業(yè)等。閥門在水處理行業(yè)中使用量較大,主要以低壓閥門產(chǎn)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(jù)結(jié)構(gòu)形式分,閘閥可分為以下類型:閘閥根據(jù)閥桿結(jié)構(gòu)可分為明桿閘閥(升降桿閘閥)和暗桿閘閥(旋轉(zhuǎn)桿閘閥)。 明桿閘閥(升降桿閘閥):通過旋轉(zhuǎn)閥桿螺母帶動(dòng)閥桿升降(不旋轉(zhuǎn))來實(shí)現(xiàn)閘板啟閉的閘閥。這種結(jié)構(gòu)閘閥對(duì)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(zhì)接觸,不受介質(zhì)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(zhuǎn)桿閘閥):閥桿螺母在閥體內(nèi)與介質(zhì)接觸,通過旋轉(zhuǎn)閥桿來實(shí)現(xiàn)閘板啟閉的閘閥。這種結(jié)構(gòu)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(zhì)接觸,要受介質(zhì)溫度和腐蝕性的影響,因而適用于非腐蝕性介質(zhì)以及外界環(huán)境條件較差的場(chǎng)合。示例如下: 螺紋連接暗桿閘閥示例根據(jù)閘板的構(gòu)造,閘閥可分為平行式閘閥和楔式閘閥。 平行式閘閥:兩個(gè)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(jī)構(gòu)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(dǎo)流孔的平板閘閥安裝在管路上還可直接用清管器進(jìn)行清管。同時(shí),由于閘板啟閉時(shí)在兩閥座密封面滑動(dòng),可適用于帶懸浮顆粒的介質(zhì)。另外,平板閘閥不會(huì)因?yàn)殚y桿熱伸長而使密封面過載。但平板閘閥存在以下缺點(diǎn): 當(dāng)介質(zhì)壓力較低時(shí),金屬密封面的密封力不足以達(dá)到滿意的密封性能; 當(dāng)介質(zhì)壓力高時(shí),經(jīng)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(zhì)時(shí),會(huì)產(chǎn)生劇烈振動(dòng); d、在圓形流道上橫向運(yùn)動(dòng)的圓形閘板只有當(dāng)它處在閥門關(guān)閉位置的50%時(shí),才對(duì)流量的控制較敏感。 楔式閘閥:兩個(gè)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(shí)現(xiàn)既能對(duì)高的介質(zhì)壓力密封,也能低的介質(zhì)壓力密封。楔式閘閥的閥體上設(shè)有導(dǎo)向機(jī)構(gòu)(導(dǎo)向筋),可防止閘板在開啟或關(guān)閉時(shí)旋轉(zhuǎn),確保閘板與閥座的密封面相應(yīng)對(duì)準(zhǔn)。同時(shí),楔式閘閥在關(guān)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(diǎn): 密封面易夾雜流動(dòng)介質(zhì)中固體顆粒; 閥桿的熱膨脹可能使密封面產(chǎn)生過載; 閘板不能設(shè)置導(dǎo)流孔。 根據(jù)JB/T 308閘閥結(jié)構(gòu)形式代號(hào)如下:結(jié)構(gòu)形式代號(hào)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(diào)壓閥型號(hào)怎么選擇呢?

    調(diào)壓閥型號(hào)怎么選擇呢?

    ? ? ? 為保證氣動(dòng)自動(dòng)化系統(tǒng)正常工作,選擇使用調(diào)壓閥應(yīng)考慮以下問題:1)根據(jù)要求的工作壓力、調(diào)壓范圍和使用流量的*大值及穩(wěn)壓精度來選擇調(diào)壓閥。根據(jù)系統(tǒng)的使用工作壓力不同,調(diào)壓閥的輸出壓力可分級(jí)供給。調(diào)壓閥的輸出流量是主要性能參數(shù),一般與閥的接管口徑相對(duì)應(yīng)。若沒有足夠大的大口徑閥供選用,可用幾個(gè)調(diào)壓閥并聯(lián)輸出。但需注意相應(yīng)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(wěn)壓精度要求較高時(shí),應(yīng)選用先導(dǎo)式減壓閥。2)在易爆有危險(xiǎn)的場(chǎng)合,應(yīng)選用遙控減壓閥(外部先導(dǎo)式)。通常,遙控減壓閥和小型直動(dòng)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(jīng)DPC空氣過濾器、DPC減壓閥和DPC油霧器后,供給氣動(dòng)裝置。3)儲(chǔ)氣罐設(shè)置在氣動(dòng)自動(dòng)化系統(tǒng)的中間氣動(dòng)裝置有時(shí)為了使工作壓力穩(wěn)定,常需設(shè)置一個(gè)儲(chǔ)氣罐。通常這種儲(chǔ)氣罐容積不大,如儲(chǔ)氣罐尺寸為200 X 800(26L),建議儲(chǔ)氣罐就近設(shè)置在減壓閥上游回路中,如上圖所示。4)安裝維護(hù)調(diào)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?yàn)闅怏w流動(dòng)方向,安裝時(shí)不能將方向搞錯(cuò)。需要時(shí),可擰下氣口堵頭,安裝壓力表。安裝前,連接管道應(yīng)用壓縮空氣將其內(nèi)灰塵、鐵屑等雜物吹掉。為了延長調(diào)壓閥的使用壽命,減壓閥不用時(shí)應(yīng)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(diào)壓閥清洗裝配時(shí),金屬零件應(yīng)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(shí),滑動(dòng)部分的表面要涂潤滑脂。膜片、密封圈極易劃傷,裝配時(shí)要注意。

  • 調(diào)壓閥工作原理是什么?

    調(diào)壓閥工作原理是什么?

          調(diào)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(zhì)通過一個(gè)小孔充到一個(gè)相對(duì)較大的腔里實(shí)現(xiàn)減壓,實(shí)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(gè)固定的壓力,那么出口腔的壓力就會(huì)一直等于這個(gè)壓力,這個(gè)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(shù)、壓力、介質(zhì)工作溫度、特殊用途(即特殊、專用閥)、驅(qū)動(dòng)能源、結(jié)構(gòu)等方式進(jìn)行了分類,其中*常用的分類法是按結(jié)構(gòu)將調(diào)節(jié)閥分為九個(gè)大類,6種為直行程,3種為角行程。
