style="font-size:16px;">選擇閥門應遵循的原則：1、截止和開放介質(zhì)用的閥門流道為直通式的閥門，其流阻較小，通常選擇作為截止和開放介質(zhì)用的閥門。向下閉合式閥門（截止閥、柱塞閥）由于其流道曲折，流阻比其他閥門高，故較少選用。在允許有較高流阻的場合，可選用閉合式閥門。2、控制流量用的閥門通常選擇易于調(diào)節(jié)流量的閥門作為控制流量用。向下閉合式閥門（如截止閥）適于這一用途，因為它的閥座尺寸與關(guān)閉件的行程之間成正比關(guān)系。旋轉(zhuǎn)式閥門（旋塞閥、蝶閥、球閥）和撓曲閥體式閥門（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口徑范圍內(nèi)適用。閘閥是以圓盤形閘板對圓形閥座口做橫切運動，它只有在接近關(guān)閉位置時，才能較好地控制流量，故通常不用于流量控制。</span> </p><p> <span style="font-size:16px;">閥門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。閥門的基本的功能是接通或切斷管路介質(zhì)的流通。利用閥門可以改變管路中的介質(zhì)流動方向，調(diào)節(jié)介質(zhì)的壓力和流量以及保護管路的安全運行。腐蝕是造成閥門損壞的重要元素之一，因此,在閥門防護中,閥門防腐是考慮的重要問題。閥門防腐該如何進行?下面為您介紹九個防腐小妙招！根據(jù)腐蝕介質(zhì)選用耐蝕材料在生產(chǎn)實際中,介質(zhì)的腐蝕是非常的復雜的，即使在用一介質(zhì)中使用的閥門材料樣,介質(zhì)的濃度、溫度、力不同,介質(zhì)對材料腐蝕也不一樣,介質(zhì)溫度每升高10C,腐蝕速度約增加1~3倍。介質(zhì)濃度對閥門材料腐蝕影響很大,如鉛處在濃度小的硫酸中，腐蝕很小，當濃度超過96%時,腐蝕急劇上升。而碳鋼相反,在硫酸濃度為50%左右時腐蝕嚴重,當濃度增加到6%以上時,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,但在中、低濃度的硝酸中腐蝕反而嚴重。不銹鋼雖說對稀硝酸耐蝕性很強,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,正確選用閥門材料應根據(jù)具體情況,分析各種影響腐蝕因素,按有關(guān)防腐手冊選用材料。</span> 要求削弱關(guān)閉水錘時，宜選用速閉消聲止回閥或有阻尼裝置的緩閉止回閥。</p><div style="width:100%;text-align: center;"><img

style="font-size:16px;">大型閥門的設(shè)置要求大型閥門的操作應使用帶齒輪傳動機構(gòu)，設(shè)置時應考慮傳動機構(gòu)所需空間位置。通常，閥門的尺寸大于下列等級的尺寸應考慮使用帶齒輪傳動機構(gòu)的閥門。大型閥門應在閥門的一側(cè)或兩側(cè)設(shè)置支架，該支架不應設(shè)在檢修時需要拆卸的短管上，并考慮拆下閥門時不應影響管道的支承。一般支架與閥門法蘭的距離應大于300mm。大型閥門的安裝位置要有使用吊</span><span style="font-size:16px;">車的場地，或考慮設(shè)吊柱、吊梁。4水平管道上閥門的設(shè)置要求除工藝另有特殊要求外，一般水平管道上安裝的閥門手輪不得朝下，尤其是危險介質(zhì)管道上的閥門嚴禁手輪朝下。閥門手輪的方位按下列順序確定：垂直向上；水平；垂直向上的左、右傾斜45°；垂直向下的左、右傾斜45°；不得垂直向下。水平安裝的明桿式閥門，當閥門開啟時，閥桿不得影響通行，特別是閥桿位于操作人員的頭部或膝部時更要注意。</span>閥門的種類多種多樣，各種閥門還有各自獨特的地方。古浪閥門廠家價格</p><p

style="font-size:16px;">閥門的密封性能是指閥門各密封部位阻止介質(zhì)泄漏的能力，它是閥門重要的技術(shù)性能指標。閥門的密封部位有三處：啟閉件與閥座兩密封面間的接觸處；填料與閥桿和填料函的配和處；閥體與閥蓋的連接處。其中前一處的泄漏叫做內(nèi)漏，也就是通常所說的關(guān)不嚴，它將影響閥門截斷介質(zhì)的能力。對于截斷閥類來說，內(nèi)漏是不允許的。后兩處的泄漏叫做外漏，即介質(zhì)從閥內(nèi)泄漏到閥外。外漏會造成物料損失，污染環(huán)境，嚴重時還會造成事故。對于易燃易爆、有毒或有放射的介質(zhì)，外漏更是不能允許的，因而閥門必須具有可靠的密封性能。介質(zhì)流過閥門后會產(chǎn)生壓力損失（既閥</span><span style="font-size:16px;">門前后的壓力差），也就是閥門對介質(zhì)的流動有一定的阻力，介質(zhì)為克服閥門的阻力就要消耗一定的能量。從節(jié)約能源上考慮，設(shè)計和制造閥門時，要盡可能降低閥門對流動介質(zhì)的阻力。</span> 古浪閥門廠家價格</p><p
