style="font-size:16px;">選擇閥門的依據(jù)在了解掌握選擇閥門步驟的同時，還應(yīng)進(jìn)一步了解選擇閥門的依據(jù)。（1）所選用閥門的用途、使用工況條件和操縱控制方式。（2）工作介質(zhì)的性質(zhì)：工作壓力、工作溫度、腐蝕性能，是否含有固體顆粒，介質(zhì)是否有毒，是否是易燃、易爆介質(zhì)，介質(zhì)的黏度等等。（3）對閥門流體特性的要求：流阻、排放能力、流量特性、密封等級等等。（4）安裝尺寸和外形尺寸要求：公稱通徑、與管道的連接方式和連接尺寸、外形尺寸或重量限制等。（5）對閥門產(chǎn)品的可靠性、使用壽命和電動裝置的防爆性能等的附加要求。在選定參數(shù)時應(yīng)注意：如果閥門要用于控制目的，必須確定如下額外參數(shù)：操作方法、比較大和**小流量要求、正常流動的壓力降、關(guān)閉時的壓力降、閥門的比較大和**小進(jìn)口壓力。根據(jù)上述選擇閥門的依據(jù)和步驟，合理、正確地選擇閥門時還必須對各種類型閥門的內(nèi)部結(jié)構(gòu)進(jìn)行詳細(xì)了解，以便能對優(yōu)先選用的閥門做出正確的抉擇。管道的終控制是閥門。閥門啟閉件控制著介質(zhì)在管道內(nèi)的流束方式，閥門流道的形狀使閥門具備一定的流量特性，在選擇管道系統(tǒng)**適合安裝的閥門時必須考慮到這一點。</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(hù)管路的安全運(yùn)行。腐蝕是造成閥門損壞的重要元素之一，因此,在閥門防護(hù)中,閥門防腐是考慮的重要問題。閥門防腐該如何進(jìn)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(fù)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(dāng)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(yán)重,當(dāng)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(qiáng),但在中、低濃度的硝酸中腐蝕反而嚴(yán)重。不銹鋼雖說對稀硝酸耐蝕性很強(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)防腐手冊選用材料。</span> 有的閥門，除了必要的保護(hù)設(shè)施外，還要有旁路和儀表。西和閥門廠家電話</p><p

style="font-size:16px;">有的閥門，除了必要的保護(hù)設(shè)施外，還要有旁路和儀表。安裝了旁路。便于疏水閥檢修。其他閥門，也有安裝旁路的。是否安裝旁路，要看閥門狀況，重要性和生產(chǎn)上的要求而定。填料更換庫存閥門，有的填料已不好使，有的與使用介質(zhì)不符，這就需要換填料。閥門制作廠無法考慮使用單位千門萬類的不同介質(zhì)，填料函內(nèi)總是裝填普通盤根，但使用時，必須讓填料于介質(zhì)相適應(yīng)。在更換填料時，要一圈一圈地壓入。每圈接縫以45度為宜，圈與圈接開180度。填料高度要考慮壓蓋繼續(xù)壓緊的余地，現(xiàn)時又要讓壓蓋下部壓填料室適當(dāng)深度，此深度一般可為填料室總深度的10-20%。對于要求高的閥門，接縫角度為30度。圈與圈之間接縫錯開120度。除上述填料之外，還可根據(jù)具體情況，采用橡膠O形環(huán)（天然橡膠耐60攝氏度以下弱堿，丁晴橡膠耐80攝氏度以下油晶，氟橡膠耐150攝氏度以下多種腐蝕介質(zhì)）三件疊式聚四氟乙烯圈（耐200攝氏度以下強(qiáng)腐蝕介質(zhì)）尼龍碗狀圈（耐120攝氏度一下氨</span><span
