style="text-indent:25px">電磁閥選型首先應(yīng)該依次遵循安全性，可靠性，適用性，經(jīng)濟(jì)性四大原則，其次是根據(jù)六個方面的現(xiàn)場工況（即管道參數(shù)、流體參數(shù)、壓力參數(shù)、電氣參數(shù)、動作方式、特殊要求進(jìn)行選擇）。選型依據(jù)：1，流量閥FKC-03-04、根據(jù)管道參數(shù)選擇電磁閥的：通徑規(guī)格（即DN）、接口方式： 1）按照現(xiàn)場管道內(nèi)徑尺寸或流量要求來確定通徑（DN）尺寸； 2）接口方式，一般>DN50要選擇法蘭接口，≤DN50則可根據(jù)用戶需要自由選擇，流量閥FKC-03-04。 2，流量閥FKC-03-04、根據(jù)流體參數(shù)選擇電磁閥的：材質(zhì)、溫度組： 1）腐蝕性流體：宜選用耐腐蝕電磁閥和全不銹鋼；食用超凈流體：宜選用食品級不銹鋼材質(zhì)電磁閥； 2）高溫流體：要選擇采用耐高溫的電工材料和密封材料制造的電磁閥，而且要選擇活塞式結(jié)構(gòu)類型的； 3）流體狀態(tài)：大至有氣態(tài)，液態(tài)或混合狀態(tài)，特別是口徑大于DN25時一定要區(qū)分開來； 4）流體粘度：通常在50cSt以下可任意選擇，若超過此值，則要選用高粘度電磁閥。單向閥用于液壓系統(tǒng)中防止油流反向流動,或者用于氣動系統(tǒng)中防止壓縮空氣逆向流動。流量閥FKC-03-04</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">單向閥有直通式和直角式兩種。直通式單向閥用螺紋連接安裝在管路上。直角式單向閥有螺紋連接、板式連接和法蘭連接三種形式。液控單向閥也稱閉鎖閥或保壓閥，它與單向閥相同，用以防止油液反向流動。但在液壓回路中需要油流反向流動時又可利用控制油壓，打開單向閥，使油流在兩個方向都可流動。液控單向閥采用錐形閥芯，因此密封性能好。在要求封閉油路時，可用此閥作為油路的單向鎖緊而起保壓作用。液控單向閥控制油的泄漏方式有內(nèi)泄式和外泄式二種。在油流反向出口無背壓的油路中可用內(nèi)泄式；否則需用外泄式，以降低控制油壓力。</p><p style="text-indent:25px">電磁換向閥如何換向求原理： 1)電磁換向閥的軸線必須按水平方向安裝，如垂直方向安裝，受閥芯、銜鐵等零件重量影響，將造成換向或復(fù)位不正常。 2)一般電磁閥兩端的油腔是泄油腔或回油腔，應(yīng)檢查該腔壓力是否過高。如果在系統(tǒng)中多個電磁閥的泄油或回油管道中接在一起造成背壓過高，則應(yīng)將它們單獨(dú)接回油箱。 3)安裝底板表面應(yīng)磨削加工，同時應(yīng)有平面度要求，不得凸起。 4)安裝螺釘不能擰得太松，否則板式連接電磁換向閥與底板的接合處滲油。 5)電磁換向閥應(yīng)注意控制電源參數(shù)應(yīng)與電磁閥一致。電磁換向閥是依靠電磁鐵的推力達(dá)到換向目的，電磁鐵分直流或交流，電磁鐵應(yīng)與控制電源參數(shù)相一致，否則有可能造成換向閥不能正常工作或燒毀電磁鐵。比例反是可以根據(jù)模擬信號按一定的比例控制閥門開度的電動或電磁調(diào)節(jié)閥。</p><div

style="text-indent:25px">安全閥結(jié)構(gòu)主要有兩大類：彈簧式和杠桿式。彈簧式是指閥瓣與閥座的密封靠彈簧的作用力。杠桿式是靠杠桿和重錘的作用力。隨著大容量的需要，又有一種脈沖式安全閥，也稱為先導(dǎo)式安全閥，由主安全閥和輔助閥組成。當(dāng)管道內(nèi)介質(zhì)壓力超過規(guī)定壓力值時，輔助閥先開啟，介質(zhì)沿著導(dǎo)管進(jìn)入主安全閥，并將主安全閥打開，使增高的介質(zhì)壓力降低。安全閥的排放量決定于閥座的口徑與閥瓣的開啟高度，也可分為兩種：微啟式開啟高度是閥座內(nèi)徑的（1/20）～（1/40），全啟式是（1/3）～（1/4）。電磁換向閥可以借助于按鈕開關(guān),行程開關(guān),限位開關(guān),壓力繼電器等發(fā)出的電信號進(jìn)行控制。流量閥FKC-03-04</p><p

style="text-indent:25px">重錘杠桿式安全閥是利用重錘和杠桿來平衡作用在閥瓣上的力。根據(jù)杠桿原理，它可以使用質(zhì)量較小的重錘通過杠桿的增大作用獲得較大的作用力，并通過移動重錘的位置(或變換重錘的質(zhì)量)來調(diào)整安全閥的開啟壓力。重錘杠桿式安全閥結(jié)構(gòu)簡單，調(diào)整到容易而又比較準(zhǔn)確，所加的載荷不會因閥瓣的升高而有較大的增加，適用于溫度較高的場合，過去用得比較普遍，特別是用在鍋爐和溫度較高的壓力容器上。但重錘杠桿式安全閥結(jié)構(gòu)比較笨重，加載機(jī)構(gòu)容易振動，并常因振動而產(chǎn)生泄漏；其回座壓力較低，開啟后不易關(guān)閉及保持嚴(yán)密。流量閥FKC-03-04</p><p
