style="font-size:16px;">閥門的布置原則閥門應(yīng)根據(jù)管道及儀表流程圖（PID）上所示類型及數(shù)量設(shè)置。當(dāng)PID對某些閥門的安裝位置有具體要求時，應(yīng)按工藝要求設(shè)置。閥門應(yīng)布置在容易接近、便于操作、維修的地方。成排管道上的閥門應(yīng)集中布置，并考慮設(shè)置操作平臺或梯子。2閥門的安裝位置要求進出裝置的管廊管道在與全廠管廊上的主管相接時，均須設(shè)置切斷用閥門。閥門的安裝位置應(yīng)集中布置在裝置區(qū)一側(cè)，并設(shè)置必要的操作平臺或檢修平臺。需要經(jīng)常操作、維修和更換的閥門，應(yīng)位于地面、平臺或梯子容易接近處。氣動和電動閥也同樣應(yīng)布置在容易接近處。不需要經(jīng)常操作的閥門（只在開停車時使用），如果在地面上無法操作時，也應(yīng)布置在能架設(shè)臨時梯子的地方。閥門手輪的中心距操作面的高度為750～1500mm之間，適宜的高度為1200mm，不需要經(jīng)常操作的閥門安裝高度可達1500～1800mm。當(dāng)安裝高度無法降低且又需要經(jīng)常操作時，設(shè)計時應(yīng)設(shè)置操作平臺或踏步。危險介質(zhì)的管道和設(shè)備上的閥門，不得在人的頭部高度范圍內(nèi)設(shè)置。閥門手輪的中心距操作面的高度超過1800mm時，宜設(shè)置鏈輪操作，鏈輪的鏈距地面宜為800mm左右，并應(yīng)設(shè)鏈輪掛鉤，</span><span style="font-size:16px;">將鏈子下端掛在附近的墻上或柱子上，以免影響通道的通行設(shè)置在管溝內(nèi)的閥門。</span> </p><p> <span style="font-size:16px;">有的閥門，除了必要的保護設(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;">閥門電動裝置是實現(xiàn)閥門程控、自控和遙控不可缺少的設(shè)備，其運動過程可由行程、轉(zhuǎn)矩或軸向推力的大小來控制。由于閥門電動裝置的工作特性和利用率取決于閥門的種類、裝置工作規(guī)范及閥門在管線或設(shè)備上的位置，因此，正確選擇閥門電動裝置，對防止出現(xiàn)超負荷現(xiàn)象（工作轉(zhuǎn)矩高于控制轉(zhuǎn)矩）至關(guān)重要。閥門電動裝置有其特殊要求，即必須能夠限定轉(zhuǎn)矩或軸向力。通常閥門電動裝置采用限制轉(zhuǎn)矩的連軸器。當(dāng)電動裝置規(guī)格確定之后，其控制轉(zhuǎn)矩也就確定了。一般在預(yù)先確定的時間內(nèi)運行，電機不會超負荷。但如出現(xiàn)下列情況便可能導(dǎo)致超負荷：一是電源電壓低，得不到所需的轉(zhuǎn)矩，使電機停止轉(zhuǎn)動；二是錯誤地調(diào)定轉(zhuǎn)矩限制機構(gòu)，使其大于停止的轉(zhuǎn)矩，造成連續(xù)產(chǎn)生過大轉(zhuǎn)矩，使電機停止轉(zhuǎn)動；三是斷續(xù)使用，產(chǎn)生的熱量積蓄，超過了電機的允許溫升值；四是因某種原因轉(zhuǎn)矩限制機構(gòu)電路發(fā)生故障，使轉(zhuǎn)矩過大；五是使用環(huán)境溫度過高，相對使電機熱容量下降。</span>
