工作原理：依靠流體自身的力量以及閥瓣的自重，自動啟閉的閥門。顧名思義，它的作用是阻止介質(zhì)倒流。一般裝在水泵出口，防止水錘對水泵造成損壞。供熱工程中常用的有水平升降式，單瓣旋啟式，雙瓣蝶式。止回閥有方向性，***不能裝反。不同形式止回閥，按其結(jié)構(gòu)，都有固定的安裝方式，切不可裝錯。水平升降式只能安裝在水平管路上，且保證閥瓣處于垂直狀態(tài)；單瓣旋啟式也只能安裝在水平管路上，且保證閥瓣轉(zhuǎn)軸處于水平狀態(tài)；雙瓣蝶式可以任意安裝。6、調(diào)節(jié)閥啟閉件（閥瓣）預(yù)定使用在關(guān)閉與全開啟任何位置，通過啟閉件（閥瓣）改變通路截面積，以調(diào)節(jié)流量、壓力或溫度的閥門，也叫節(jié)流閥，是供熱系統(tǒng)二次網(wǎng)的常用閥門。工作原理：外形、結(jié)構(gòu)與截止閥相似。只是密封副不同，調(diào)節(jié)閥的閥瓣和閥座類似暖水瓶的瓶塞和瓶口，新疆陶瓷耐磨閥門批發(fā)廠，通過閥瓣的移動改變過流面積來調(diào)節(jié)流量。在閥軸上有標尺表示相應(yīng)流量。作用：調(diào)節(jié)管路間介質(zhì)流量分配以達到熱力平衡。供熱工程中曾使用的是直通式，但它有一些缺點：流阻大，新疆陶瓷耐磨閥門批發(fā)廠，不宜垂直安裝。于是隨著技術(shù)的進步，平衡閥代替了調(diào)節(jié)閥。7、平衡閥改進型調(diào)節(jié)閥。有方向性，新疆陶瓷耐磨閥門批發(fā)廠，可以水平裝，也可以垂直裝。流道采用直流式，閥座改為聚四氟乙烯；克服了流阻大的缺點。烏魯木齊市高壓油田閥門經(jīng)銷商。新疆陶瓷耐磨閥門批發(fā)廠</p><div

如果焊接上接口，閥門必須打開，如果焊接下接口，閥門必須關(guān)閉，以免閥門內(nèi)部被高熱灼傷。4、蝶閥啟閉件（蝶板）由閥桿帶動，并繞閥桿的軸線作旋轉(zhuǎn)運動的閥門。蝶閥也叫蝴蝶閥，顧名思義，它的關(guān)鍵性部件好似蝴蝶迎風，自由回旋。在供熱系統(tǒng)中，目前是使用*****，種類也**多的一種閥門。蝶閥具有輕巧的特點，比其他閥門要節(jié)省材料，結(jié)構(gòu)簡單，開閉迅速，切斷和節(jié)流都能用，流體阻力小，操作省力。蝶閥，可以做成很大口徑。能夠使用蝶閥的地方，比較好不要使閘閥，因為蝶閥比閘閥經(jīng)濟，而且調(diào)節(jié)性好。目前，蝶閥在熱水管路得到***的使用。工作原理：閥瓣是一個圓盤，通過閥桿旋轉(zhuǎn)，閥瓣在閥座范圍內(nèi)作90℃轉(zhuǎn)動，實現(xiàn)閥門的開關(guān)。它在管路中起關(guān)斷作用，亦可調(diào)節(jié)流量。優(yōu)點：結(jié)構(gòu)簡單，體積輕巧，操作方便，密封性好。缺點：全開時，閥板（密封圈）受介質(zhì)沖蝕。在供熱工程中，用到的蝶閥有三偏心金屬密封蝶閥，橡膠軟密封蝶閥。（1）三偏心金屬密封蝶閥所謂“三偏心”是指閥軸、閥板在閥門內(nèi)相對位置的偏移。普通的蝶閥都是一個偏心，即閥軸中心線與密封面中心線（閥板中心線）偏離；高性能的再加一個偏心，即閥軸中心線與閥門中心線（管道中心線）偏離。新疆烏市各種進口閥門廠家推薦。</p><div

同時增加了兩個優(yōu)點：密封更合理、兼有截止功能。供熱工程中在熱力站二次網(wǎng)上使用，具有優(yōu)異的流量調(diào)節(jié)特性，特別適用于變流量系統(tǒng)。8、自力式平衡閥自力式平衡閥也叫流量控制閥。工作原理：在閥門內(nèi)有一個由彈簧與橡膠膜組成的機構(gòu)，它與閥桿連接。如果流量增大，會在其上產(chǎn)生一個不平衡力，使得閥瓣向關(guān)閉方向移動，以減少過流面積，降低流量，使流量回歸設(shè)定值。反之亦然。由此始終保持閥后流量不變，達到控制流量的目的。安裝在供熱系統(tǒng)的熱人口，分支點。自動消除水力失調(diào)，提高系統(tǒng)效能，實現(xiàn)經(jīng)濟運行。自力式平衡閥有方向性，切勿裝反。9、安全閥當介質(zhì)壓力超過規(guī)定數(shù)值時，閥門能自動開啟并泄壓，當壓力正常后，又能自動閉合，以保證系統(tǒng)正常運行，起這種作用的閥門叫安全閥。按結(jié)構(gòu)分有：彈簧式、杠桿式、脈沖式。按動作量分：閥瓣開啟高度與閥座通徑之比10%以下叫微啟式，20%-30%叫全啟式。按排泄方式分：介質(zhì)通過管道排走叫封閉式，直接排向空中叫敞開式?，F(xiàn)以彈簧式為例作一簡述：彈簧力與介質(zhì)作用于閥瓣的正常壓力相平衡，使密封面閉合；當介質(zhì)壓力過高時，彈簧受到壓縮，閥板開啟，介質(zhì)從中泄出；當壓力回降到正常值時，彈簧力又將閥門關(guān)閉。烏魯木齊工業(yè)管道閥門專賣店。上海工業(yè)管道閥門批發(fā)</p><p

閥門是管路系統(tǒng)中用途**廣的控制部件。在管路中起開通、關(guān)閉、調(diào)節(jié)流量和調(diào)節(jié)壓力的作用。如果管路中沒有閥門，管路的功能就根本無法實現(xiàn)。管路中閥門的配置和安裝不合理，同樣也會影響管路的功能。閥門選用的基本原則選擇閥門首先要清楚工藝要求，要符合壓力、溫度和介質(zhì)特性，其次要清楚功能要求，是自動還是手動，是切斷還是調(diào)節(jié)，是嚴格切斷還是基本切斷。正確、合理的選用閥門，可以獲得**經(jīng)濟的使用壽命和比較好的性能用途。閥門選用的一般通則a、管徑≤50mm，宜采用銅截止閥或銅球閥，管徑≥50cm，宜采用閘閥或蝶閥；b、管徑小宜采用螺紋連接，管徑大宜采用法蘭連接；c、安裝空間小的部位宜采用球閥，如必須采用閘閥，要選暗桿式。d、要求流動阻力小的部位，宜采用閘閥；e、需雙向流動的管段上宜采用閘閥、球閥；f、需調(diào)節(jié)流量、壓力時，宜采用截止閥；g、經(jīng)常啟閉的部位宜采用截止閥，不經(jīng)常啟閉的部位采用閘閥。黃銅球閥優(yōu)點：結(jié)構(gòu)簡單，流動阻力小，啟閉迅速，操作方便，可以作成直通、三通和四通式結(jié)構(gòu)，能輸送帶懸浮顆粒和粘度較大的介質(zhì)。缺點：制造精度要求高，閥體重量大，不能用于含有泥沙和結(jié)晶體的物料輸送，關(guān)斷性差，不調(diào)節(jié)流量功能。
