style="font-size:16px;">閥門(mén)作為流體管路的控制裝置，是隨著管路的產(chǎn)生而產(chǎn)生的。閥門(mén)的基本的功能是接通或切斷管路介質(zhì)的流通。利用閥門(mén)可以改變管路中的介質(zhì)流動(dòng)方向，調(diào)節(jié)介質(zhì)的壓力和流量以及保護(hù)管路的安全運(yùn)行。腐蝕是造成閥門(mén)損壞的重要元素之一，因此,在閥門(mén)防護(hù)中,閥門(mén)防腐是考慮的重要問(wèn)題。閥門(mén)防腐該如何進(jìn)行?下面為您介紹九個(gè)防腐小妙招！根據(jù)腐蝕介質(zhì)選用耐蝕材料在生產(chǎn)實(shí)際中,介質(zhì)的腐蝕是非常的復(fù)雜的，即使在用一介質(zhì)中使用的閥門(mén)材料樣,介質(zhì)的濃度、溫度、力不同,介質(zhì)對(duì)材料腐蝕也不一樣,介質(zhì)溫度每升高10C,腐蝕速度約增加1~3倍。介質(zhì)濃度對(duì)閥門(mén)材料腐蝕影響很大,如鉛處在濃度小的硫酸中，腐蝕很小，當(dāng)濃度超過(guò)96%時(shí),腐蝕急劇上升。而碳鋼相反,在硫酸濃度為50%左右時(shí)腐蝕嚴(yán)重,當(dāng)濃度增加到6%以上時(shí),腐蝕反而急劇下降。鋁在濃度80%以上的濃硝酸中腐蝕性很強(qiáng),但在中、低濃度的硝酸中腐蝕反而嚴(yán)重。不銹鋼雖說(shuō)對(duì)稀硝酸耐蝕性很強(qiáng),但在95%以上的濃硝酸中腐蝕反而加重</span><span style="font-size:16px;">。從以上幾例可以看出,正確選用閥門(mén)材料應(yīng)根據(jù)具體情況,分析各種影響腐蝕因素,按有關(guān)防腐手冊(cè)選用材料。</span> </p><p> <span style="font-size:16px;">我國(guó)閥門(mén)裝備制造業(yè)前景寬廣，未來(lái)閥門(mén)產(chǎn)業(yè)**化、國(guó)產(chǎn)化，現(xiàn)代化、將是今后閥門(mén)行業(yè)發(fā)展主要方向。閥門(mén)是管路流體輸送系統(tǒng)中控制部件，用來(lái)改變通路斷面和介質(zhì)流動(dòng)方向，具有導(dǎo)流、截止、節(jié)流、止回、分流或溢流卸壓等功能。閥門(mén)的運(yùn)動(dòng)部件在運(yùn)動(dòng)時(shí)不僅會(huì)產(chǎn)生摩擦，造成運(yùn)動(dòng)表面的磨損；而且還會(huì)在工作介質(zhì)的壓力下，增大運(yùn)動(dòng)阻力，使摩擦加劇，磨損加速?gòu)亩归y門(mén)使用壽命縮短；另外在閥門(mén)靜止時(shí)，由于工作介質(zhì)的壓力和閥門(mén)的預(yù)緊力，會(huì)使閥門(mén)的運(yùn)動(dòng)表面發(fā)生冷焊現(xiàn)象，使閥門(mén)操作困難，甚至不能操作。閥門(mén)選擇正確密封潤(rùn)滑</span><span

style="font-size:16px;">選擇閥門(mén)應(yīng)遵循的原則：1、截止和開(kāi)放介質(zhì)用的閥門(mén)流道為直通式的閥門(mén)，其流阻較小，通常選擇作為截止和開(kāi)放介質(zhì)用的閥門(mén)。向下閉合式閥門(mén)（截止閥、柱塞閥）由于其流道曲折，流阻比其他閥門(mén)高，故較少選用。在允許有較高流阻的場(chǎng)合，可選用閉合式閥門(mén)。2、控制流量用的閥門(mén)通常選擇易于調(diào)節(jié)流量的閥門(mén)作為控制流量用。向下閉合式閥門(mén)（如截止閥）適于這一用途，因?yàn)樗拈y座尺寸與關(guān)閉件的行程之間成正比關(guān)系。旋轉(zhuǎn)式閥門(mén)（旋塞閥、蝶閥、球閥）和撓曲閥體式閥門(mén)（夾緊閥、隔膜閥）也可用于節(jié)流控制，但通常只能在有限的閥門(mén)口徑范圍內(nèi)適用。閘閥是以圓盤(pán)形閘板對(duì)圓形閥座口做橫切運(yùn)動(dòng)，它只有在接近關(guān)閉位置時(shí)，才能較好地控制流量，故通常不用于流量控制。</span>
