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攝氏度以下強腐蝕介質(zhì)）尼龍碗狀圈（耐120攝氏度一下氨</span><span

style="font-size:16px;">閥門填料閥門密封的關(guān)鍵因素壓縮填料填料是一種傳統(tǒng)的壓蓋密封,可以采用多種材料制造。用填料裝填填料時,填料在結(jié)構(gòu)上可以為散狀的(通?；旌嫌袧櫥瑒?；制成一定斷面(一般為矩形,但有時也用圓形截面);切成適當(dāng)長度</span><span style="font-size:16px;">繞成螺旋狀的或者作為切制圖,裝在壓蓋上的成型件。無論采用哪種結(jié)構(gòu),都是靠壓緊壓蓋,迫使填料緊壓在密封表面上而取得密封作用的。由于壓緊壓蓋所形成的壓緊力產(chǎn)生一種造成密封效果的徑向壓力。徑向壓力沿整個填料長度按指數(shù)曲線分布。為了保持填料的“干”狀態(tài),內(nèi)側(cè)圈上的徑向壓力至少要等于系統(tǒng)的內(nèi)壓力,這就意味著外側(cè)圈上的徑向壓力高得多,在大多數(shù)用途中是過高的(導(dǎo)致過大的摩擦,軸磨損和氣動密封件失效)。因此,在大多數(shù)使用中,要將壓緊力調(diào)整到允許末一個圈填料稍有一點泄漏,也就是說這個環(huán)上的徑向壓力稍微低于系統(tǒng)的內(nèi)壓力。然而,這樣一來,如果將壓蓋調(diào)整到不產(chǎn)生泄漏的小壓縮程度時,則大多數(shù)填料圈上就將出現(xiàn)一些泄漏。</span> </p><p> <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清潔環(huán)，有些情況下頂部也可安裝一個。截止閥較常采用升桿加旋轉(zhuǎn)運動模式，它的密封難度比較大，因為閥桿會同時在兩個方向上同時運動，盤根組會逐步接觸到整個閥桿的表面。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>
