MPa的超高壓閥門(mén),溫度從深冷-196℃到高溫570℃。使用介質(zhì)為水、蒸汽、尿素、乙烯、易爆等介質(zhì)。閥門(mén)是利潤(rùn)率低的產(chǎn)品,市場(chǎng)競(jìng)爭(zhēng)非常激烈。閥門(mén)在水處理行業(yè)中使用量大,主要以低壓閥門(mén)產(chǎn)品為主,如蝶閥、閘閥、止回閥。據(jù)了解,目前市場(chǎng)上具有一定規(guī)模的閥門(mén)企業(yè)有2000余家,大多數(shù)分布在江浙及中原一帶。目前我國(guó)在閥門(mén)市場(chǎng)中，已經(jīng)能夠提供多種產(chǎn)品：例如供熱閥，環(huán)保用閥、建筑用閥門(mén)等等。盡管近些年通過(guò)國(guó)內(nèi)企業(yè)的努力，一些中較高泵閥產(chǎn)品已經(jīng)實(shí)現(xiàn)了國(guó)產(chǎn)化，但是仍有一些產(chǎn)品處于進(jìn)口狀態(tài)。據(jù)我國(guó)通用機(jī)械工業(yè)協(xié)會(huì)提供的數(shù)據(jù)，2013年以來(lái)我國(guó)進(jìn)口量較大的泵產(chǎn)品主要包括：液壓往復(fù)式柱塞泵，其它液壓往復(fù)式排液泵，回轉(zhuǎn)式軸向柱塞泵，轉(zhuǎn)速在10000轉(zhuǎn)/分以下的其它離心泵、液體泵零件、真空泵等。閥門(mén)產(chǎn)品主要包括：減壓閥、油壓傳動(dòng)閥、氣壓傳動(dòng)閥、安全閥或溢流閥、閥門(mén)零件等。在高壓閥門(mén)領(lǐng)域仍然依賴(lài)進(jìn)口，這也是我國(guó)閥門(mén)需要突破的領(lǐng)域。濟(jì)南閥門(mén)電裝批發(fā)價(jià)格檢查閥桿和閥瓣開(kāi)啟是否靈活，有無(wú)卡住和歪斜現(xiàn)象。</p><div

style="text-indent:25px">蝶閥工作原理：蝶板由閥桿帶動(dòng)，若轉(zhuǎn)過(guò)90°，便能完成一次啟閉。改變蝶板的偏轉(zhuǎn)角度，即可控制介質(zhì)的流量。碟閥作用蝶閥適用于發(fā)生爐、煤氣、天然氣、液化石油氣、城市煤氣、冷熱空氣、化工冶煉和發(fā)電環(huán)保、建筑給排水等工程系統(tǒng)中輸送各種腐蝕性、非腐蝕性流體介質(zhì)的管道上，用于調(diào)節(jié)和截?cái)嘟橘|(zhì)的流動(dòng)。試壓方法氣動(dòng)蝶閥的強(qiáng)度試驗(yàn)與截止閥一樣。蝶閥的密封性能試驗(yàn)應(yīng)從介質(zhì)流人端引入試驗(yàn)介質(zhì)，蝶板應(yīng)開(kāi)啟，另一端封閉，注入壓力至規(guī)定值。檢查填料和其他密封處無(wú)滲漏后，關(guān)閉蝶板，打開(kāi)另一端，檢查蝶板密封處無(wú)滲漏為合格。作為調(diào)節(jié)流量用的蝶閥可不做密封性能試驗(yàn)。</p><p
