2.機(jī)動(dòng)換向閥：又稱行程閥,它主要用來控制液壓機(jī)械運(yùn)動(dòng)部件的行程，它是借助于安裝在工作臺(tái)上的擋鐵或凸輪來迫使閥芯移動(dòng)，從而控制油液的流動(dòng)方向。機(jī)動(dòng)換向閥通常是二位的,有二通、三通、四通和五通幾種,其中二位二三通機(jī)動(dòng)閥又分常閉和常開兩種。3.電磁換向閥：利用電磁鐵的通、斷電而直接推動(dòng)閥芯來控制油口的連通狀態(tài)。4.液動(dòng)換向閥 5.電液換向閥：由電磁換向閥和液動(dòng)換向閥組合而成。　</p><p style="text-indent:25px">直動(dòng)式電磁閥：原理：通電時(shí)，電磁線圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起，閥門打開；斷電時(shí)，電磁力消失，彈簧把關(guān)閉件壓在閥座上，閥門關(guān)閉。特點(diǎn)：在真空、負(fù)壓、零壓時(shí)能正常工作，但通徑一般不超過25mm。分步直動(dòng)式電磁閥：原理：它是一種直動(dòng)和先導(dǎo)式相結(jié)合的原理，當(dāng)入口與出口沒有壓差時(shí)，通電后，電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起，閥門打開。當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí)，通電后，電磁力先導(dǎo)小閥，主閥下腔壓力上升，上腔壓力下降，從而利用壓差把主閥向上推開；斷電時(shí)，先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件，向下移動(dòng)，使閥門關(guān)閉。特點(diǎn)：在零壓差或真空、高壓時(shí)亦能可動(dòng)作，但功率較大，要求必須水平安裝。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。</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(shí)，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(hào)進(jìn)行控制。馬鞍山零泄漏電磁閥</p><p

1、彈簧式：液體由下而上，依靠壓力頂起彈簧控制的閥瓣，壓力消失后，彈簧力將閥瓣壓下，封閉液體倒流。常用于通徑較小的止回閥。 2、重力式：和彈簧式相似，依靠閥瓣的自身重力封閉，防止倒流。 3、旋啟式：液體在閥體內(nèi)直通，依靠壓力頂開一側(cè)的旋轉(zhuǎn)閥瓣，壓力失去后，閥瓣依靠自重回位，反向的液體壓力封閉閥瓣。 4.塑料隔膜式: 外殼和隔膜均為塑料.一般外殼為ABS,PE,PP,NYLON, PC.隔膜有硅樹脂,氟樹脂等。其它的單向閥（止回閥），如排污的止回閥，人防的防爆閥和液體使用的止回閥的原理是大同小異。嘉興氣動(dòng)電磁調(diào)節(jié)閥銷售</p><p
