style="font-size:16px;">在流體管道系統(tǒng)中，調(diào)節(jié)閥是控制元件，其投資約占管道工程費(fèi)用的30%～50%。閥門的主要功能為啟閉、節(jié)流、調(diào)節(jié)流量、隔離設(shè)備和管道系統(tǒng)、防止介質(zhì)倒流、調(diào)節(jié)和排泄壓力等。閥門也是管路中**復(fù)雜的元件，它一般由多個(gè)零部件裝配而成，技術(shù)含量高。隨著石油化工工業(yè)的迅速發(fā)展，石油化工生產(chǎn)裝置中的介質(zhì)大多具有毒性大、可燃、易爆和腐蝕性強(qiáng)的特點(diǎn)，運(yùn)行工況較復(fù)雜苛刻，操作溫度和壓力較高，開工周期長，閥門一旦出現(xiàn)故障，輕者導(dǎo)致介質(zhì)泄漏，既污染環(huán)境又造成經(jīng)濟(jì)損失，重者導(dǎo)致裝置停工停產(chǎn)，甚至造成惡性事故。因而，在管</span><span

style="font-size:16px;">閥門尺寸同樣也是影響密封元件選擇的一大因素。就小尺寸閥門而言，閥桿與填料函內(nèi)壁之間的環(huán)形截面較小。有些情況下小不一定是好事，因?yàn)樗鼤拗泼芊庠倪x擇范圍。小型閥門的環(huán)形截面通常*有.125”，很難安裝材質(zhì)堅(jiān)固、設(shè)計(jì)新穎的密封元件。大尺寸閥門也不是說沒問題了。尺寸大可能導(dǎo)致施加在閥桿和盤根組上的載荷過大。閥門振動時(shí)，產(chǎn)生的作用力對于標(biāo)準(zhǔn)密封元件</span><span style="font-size:16px;">可能太**型閥門不同截面部位的溫差也較大，可能導(dǎo)致結(jié)構(gòu)變形。對大多數(shù)類型的閥門而言，填料函尺寸理想的比例是空腔高度大約是橫截面直徑的三至五倍。如果是密封要求不高的直角回轉(zhuǎn)閥，即使填料函較淺也能有效密封。太深的填料函首先意味著密封組件容易固結(jié)，導(dǎo)致密封應(yīng)力損失，進(jìn)而發(fā)生泄漏。其次就是對閥桿的摩擦力較高，在有些應(yīng)用場合會成為阻礙。</span> </p><p> <span style="font-size:16px;">確定閥門的端部連接在螺紋連接、法蘭連接、焊接端部連接中，前兩種常用。螺紋連接的閥門主要是公稱通徑在50mm以下的閥門，如果通徑尺寸過大，連接部的安裝和密封十分困難。法蘭連接的閥門，其安裝和拆卸都比較方便，但是較螺紋連接的閥門笨重，價(jià)格較高，故它適用于各種通徑和壓力的管道連接。焊接連接適用于較荷刻的條件下，比法蘭連接更為可靠。但是焊接連接的閥門拆卸和重新安裝都比較困難，所以它的使用***于通常能長期可靠地運(yùn)行，或使用條件荷刻、溫度較高的場合；閥門材質(zhì)的選擇選擇閥門的殼體、內(nèi)件和密封面的材質(zhì)，除了考慮工作介質(zhì)的物理性能（溫度、壓力）和化學(xué)性能（腐蝕性）外，還應(yīng)掌握介質(zhì)的清潔程度（有無固體顆粒），除此之外，還要參照國家和使用部門的有關(guān)規(guī)定。正確合理的選擇閥門的材質(zhì)可以獲得閥門**經(jīng)濟(jì)的使用壽命和比較好的使用性能。閥體材料選用順序?yàn)椋鸿T鐵-碳鋼-不銹鋼，密封圈材料選用順序?yàn)椋合鹉z-銅-合金鋼-F4。</span>

style="font-size:16px;">閥門類型對密封解決方案的選擇有很大影響。升桿閘閥的開-關(guān)行程通常較長。如果操作較為頻繁，此類長行程線性運(yùn)動會給密封帶來難度。多數(shù)情況下，此類閥門的操作頻度不會超過每星期一次，甚至每年只操作一次。盤根壓蓋、閥桿和填料函之間的間隙非常重要。如果縫隙較大，線性運(yùn)動會導(dǎo)致部分密封元件被擠入，或拖曳雜質(zhì)微粒穿過密封元件。因此可在底部裝一個(gè)清潔環(huán)，有些情況下頂部也可安裝一個(gè)。截止閥較常采用升桿加旋轉(zhuǎn)運(yùn)動模式，它的密封難度比較大，因?yàn)殚y桿會同時(shí)在兩個(gè)方向上同時(shí)運(yùn)動，盤根組會逐步接觸到整個(gè)閥桿的表面。閥桿如有任何偏心或失圓，都可能導(dǎo)致盤根元件破損并泄漏。和閘閥的情況相似，線性運(yùn)動會拖曳雜質(zhì)微粒穿過密封元件，然后進(jìn)入工藝流體。</span>
