style="text-indent:25px">球閥按結構形式可分為浮動球球閥、固定球球閥、彈性球球閥； ①浮動球球閥：球閥的球體是浮動的，在介質壓力作用下，球體能產生一定的位移并緊壓在出口端的密封面上，保證出口端密封。浮動球球閥的結構簡單，密封性好，但球體承受工作介質的載荷全部傳給了出口密封圈，因此要考慮密封圈材料能否經受得住球體介質的工作載荷。這種結構，大范圍用于中低壓球閥。 ②固定球球閥:球閥的球體是固定的，受壓后不產生移動。固定球球閥都帶有浮動閥座，受介質壓力后，閥座產生移動，使密封圈緊壓在球體上，角座閥，以保證密封。通常在與球體的上、下軸上裝有軸承，操作扭距小，適用于高壓和大口徑的閥門。為了減少球閥的操作扭矩和增加密封的可靠程度，出現了油封球閥，密封面間壓注特制的潤滑油，以形成一層油膜，即增強了密封性，又減少了操作扭矩，更適用高壓大口徑的球閥。 ③彈性球球閥:球體和閥座密封圈都采用金屬材料制造，密封比壓很大，角座閥，依靠介質本身的壓力已達不到密封的要求，必須施加外力。這種閥門適用于高溫高壓介質。彈性球體是在球體內壁的下端開一條彈性槽，角座閥，而獲得彈性。當關閉通道時，用閥桿的楔形頭使球體漲開與閥座壓緊達到密封。閥門的分類那么多，該怎么選擇？角座閥</p><div style="width:100%;text-align:

style="text-indent:25px">水閥是一種閥門也稱疏水器，排水閥是將蒸汽系統中的凝結水、空氣和二氧化碳氣體盡**出，同時大限度地自動防止蒸汽的泄漏。疏水閥的品種很多，各有不同的性能。選用疏水閥時，首先應選其特性能滿足蒸汽加熱設備的運行，然后才考慮其他客觀條件，這樣選擇你所需要的疏水閥才是正確和有效的。像自由浮球式蒸汽疏水閥就是利用浮力原理，浮球根據凝結水量的多少，隨水位的變化而作升降，自動調節(jié)閥座孔的開度，連續(xù)排放凝結水，當凝結水停止進入時，浮球降的底部，回到關閉位置，排水停止，由于排水閥座孔總是在凝結水位以下，形成水封、水、氣自然分離，達到無蒸汽泄漏。角座閥閥門的構成部件主要是什么？</p><div

style="text-indent:25px">鍛鋼閥門是指關閉件（閘板）沿通路中線的垂直方向移動的閥門。鍛鋼閥門是用精煉的鍛鋼制作的閘閥，主要用在火力電站各種系統的管路上，可以控制空氣、水、蒸汽、油、液態(tài)金屬和放射介質等流體的流動。鍛鋼閥門相比較其它的閥門有：耐高溫高壓，獨特的自密封設計，壓力越高，密封越可靠等特點。由于性能技術特性、工況的特殊使產品也形成了其他產品所替代不了的特點。鍛鋼閘閥是使用很廣的一種閥門，一般口徑DN≥500mm的切斷裝置都選用它，有時口徑很小的切斷裝置也選用閘閥。閘閥作為一種級別較低的閥門，比較常見。</p><p style="text-indent:25px">減壓閥、安全閥、穩(wěn)壓閥、泄壓閥這幾個都屬于壓力閥門，主要是功能上的區(qū)別： ①減壓閥是將壓力高的介質降為壓力低的介質的設備，該閥的特點，是在進口壓力不斷變化的情況下，保持出口聽壓力和溫度值在一定的范圍內。 ②安全閥用以防止鍋爐、壓力容器等設備或管道因超壓而發(fā)生損壞的閥門。當壓力略高于正常工作壓力時，安全閥自動開啟，使壓力下降。當壓力略低于正常工作壓力時，安全閥自動關閉，停止排放流體并保持密封。 ③泄壓閥主要是用在壓力過大的場合，當壓力大于設定值時閥內片被頂開及時釋放壓力，壓力減小后恢復到原來的位置，和安全閥區(qū)別不大，泄壓閥多指用于液體的，安全閥多指用于氣體，蒸汽的。 ④穩(wěn)壓閥是將一個區(qū)域內的介質保持在一定的壓力范圍的設備。和減壓閥的區(qū)別： ⑤減壓閥：無論進口壓力如何變化，都把出口壓力減到額定值，起到減壓作用。 ⑥穩(wěn)壓閥：無論下游壓力和需求量如何變化，都維持一個恒定的上游壓力。安全閥及減壓閥是兩種閥門類型，是**閥門。其中，安全閥屬于安全泄發(fā)裝置，是**閥門，只在工作壓力超過允許范圍時動作，對系統起到保護作用。減壓閥屬于工藝閥門，可使高壓物流減壓，以滿足后系統對壓力的要求，其工作過程是連續(xù)的。不同類型的閥門用于不同的地方。</p><div

style="text-indent:25px">分溢流閥、減壓閥、順序閥這三種閥都是壓力控制閥，他們的工作原理基本相同，都是以壓力油的控制壓力來使閥口啟閉。不同點的是減壓閥主要是用來降低液壓系統某一分支油路的壓力，使分支壓力比主油路壓力低且穩(wěn)定，在調定壓力的范圍內，減壓閥也像溢流閥那樣是關閉的。但是隨著系統壓力的升高當達到減壓閥調定的壓力時，減壓閥打開，部分油液會經過他返回油箱（此時有一定壓力的油回油箱，油箱的油溫會上升），這一支路的油壓是不會上升了。減壓閥起到對本支路的減壓與穩(wěn)壓作用。溢流閥則不同，它裝在泵的出口處會保證系統的整體壓力穩(wěn)定且不會超壓。可以說溢流閥是被動工作，而減壓閥是主動工作。閥門的維護方法有哪些？gsr防爆電磁閥</p><p
