質(zhì)量關(guān)|良工閥門(mén)產(chǎn)品通過(guò)-196℃低溫試驗(yàn)良工閥門(mén)集團(tuán)2017-01-08點(diǎn)擊上方“良工閥門(mén)集團(tuán)”關(guān)注我們。低溫閥門(mén)通常是指工作溫度在-40℃以下的閥門(mén),隨著空分、液化天然氣、乙烯石化等工業(yè)的發(fā)展，近年來(lái)，低溫閥門(mén)的市場(chǎng)需求逐年上升,應(yīng)用領(lǐng)域也越來(lái)越***。低溫閥門(mén)已成為閥門(mén)產(chǎn)品中的一個(gè)重要分支，而閥門(mén)的低溫試驗(yàn)裝置是低溫閥門(mén)生產(chǎn)過(guò)程中不可或缺的關(guān)鍵設(shè)備。完整的、符合要求的閥門(mén)低溫試驗(yàn)裝置不僅是低溫閥門(mén)生產(chǎn)和質(zhì)量控制的保證，同時(shí)，也是低溫閥門(mén)生產(chǎn)能力的重要象征。良工閥門(mén)集團(tuán)的低溫閥門(mén)試驗(yàn)裝置主要用來(lái)進(jìn)行低溫閥門(mén)零部件深冷處理和閥門(mén)低溫型式試驗(yàn)。按有關(guān)標(biāo)準(zhǔn)規(guī)定,工作溫度低于-100℃的低溫閥門(mén)，其主要零部件在精加工前應(yīng)進(jìn)行深冷處理，目的是減少由于溫差和金相組織改變而產(chǎn)生的變形。低溫試驗(yàn)主要是檢驗(yàn)在低溫工作環(huán)境下，低溫閥門(mén)的整機(jī)性能，這是一項(xiàng)要定期進(jìn)行的工作。2015年12月26日良工閥門(mén)集團(tuán)有限公司2015年分歲酒在良工閥門(mén)集團(tuán)總部隆重召開(kāi)。良工閥門(mén)集團(tuán)董事長(zhǎng)潘成桃、總經(jīng)理潘成漲、麗水工廠總經(jīng)理潘成曉、副總經(jīng)理陳永春、安全閥工廠總經(jīng)理姜振東、法蘭管件工廠總經(jīng)理黃建國(guó)等領(lǐng)導(dǎo)出席會(huì)議。新疆閥門(mén)銷(xiāo)售廠家烏魯木齊市耐酸堿閥門(mén)公司推薦。</p><div

style="text-indent:25px">閘閥的啟閉件是閘板，閘板的運(yùn)動(dòng)方向與流體方向相垂直，閘閥只能作全開(kāi)和全關(guān)，不能作調(diào)節(jié)和節(jié)流。閘板有兩個(gè)密封面，**常用的模式閘板閥的兩個(gè)密封面形成楔形、楔形角隨閥門(mén)參數(shù)而異，通常為5°，介質(zhì)溫度不高時(shí)為2°52'。楔式閘閥的閘板可以做成一個(gè)整體，叫做剛性閘板；也可以做成能產(chǎn)生微量變形的閘板，以改善其工藝性，彌補(bǔ)密封面角度在加工過(guò)程中產(chǎn)生的偏差，這種閘板叫做彈性閘板。閘閥關(guān)閉時(shí)，密封面可以只依靠介質(zhì)壓力來(lái)密封，即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來(lái)保證密封面的密封，這就是自密封。大部分閘閥是采用密封的，即閥門(mén)關(guān)閉時(shí)，要依靠外力強(qiáng)行將閘板壓向閥座，以保證密封面的密封性。</p><p> 當(dāng)毛細(xì)管的直徑和氣體分子的平均自由度相同時(shí)，氣體分子就會(huì)以自由的熱運(yùn)動(dòng)流進(jìn)毛細(xì)管。因此，當(dāng)我們?cè)谧鲩y門(mén)密封試驗(yàn)的時(shí)候，介質(zhì)一定要用水才能起到密封的作用，用空氣即氣體就不能起到密封的作用。即使我們通過(guò)塑性變形方式，將毛細(xì)管直徑降到氣體分子以下，也仍然不能阻止氣體的流動(dòng)。原因在于氣體仍然可以通過(guò)金屬壁擴(kuò)散。所以我們?cè)谧鰵怏w試驗(yàn)時(shí)，一定要比液體試驗(yàn)更加的嚴(yán)格。泄漏通道的密封原理閥門(mén)密封由散布在波形面上的不平整度和波峰間距離的波紋度構(gòu)成粗糙度兩個(gè)部分組成。閥門(mén)密封由散布在波形面上的不平整度和波峰間距離的波紋度構(gòu)成粗糙度兩個(gè)部分組成。在我國(guó)大部分的金屬材料彈性應(yīng)變力都較低的情況下，如果要達(dá)到密封的狀態(tài)，就需要對(duì)金屬材料的壓縮力提更高的要求，即材料的壓縮力要超過(guò)其彈性。因此，在進(jìn)行閥門(mén)設(shè)計(jì)時(shí)，密封副結(jié)合一定的硬度差來(lái)匹配，在壓力的作用下，就會(huì)產(chǎn)生一定程度的塑性變形密封的效果。如果密封表面都是金屬材料，那么表面不平整的凸出點(diǎn)就會(huì)**早的出現(xiàn)，在**初只需用較小的載荷就可以使這些不平整的凸出點(diǎn)產(chǎn)生塑性變形。當(dāng)接觸面增大時(shí)，表面的不平整就會(huì)變成塑性-彈性變形。這時(shí)處在凹處的兩面粗糙度就會(huì)存在。烏魯木齊各種進(jìn)口閥門(mén)專(zhuān)賣(mài)店。</p><div
