單向閥是流體只能沿進(jìn)水口流動(dòng)，出水口介質(zhì)卻無(wú)法回流，俗稱(chēng)單向閥。單向閥又稱(chēng)止回閥或逆止閥。用于液壓系統(tǒng)中防止油流反向流動(dòng),或者用于氣動(dòng)系統(tǒng)中防止壓縮空氣逆向流動(dòng)。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。

sun閥的類(lèi)型
  SUN閥產(chǎn)自美國(guó)，其閥的種類(lèi)可分為：插式閥，平衡閥，泄壓閥，順序閥，單向閥，分流閥，方向閥，電磁閥，邏輯閥，梭閥，回路節(jié)省閥，等等。
溢流閥一般有兩種結(jié)構(gòu)：1、直動(dòng)型溢流閥 。2、先導(dǎo)式溢流閥。
對(duì)溢流閥的主要要求：調(diào)壓范圍大，調(diào)壓偏差小，壓力振擺小，動(dòng)作靈敏，過(guò)載能力大，噪聲小。
1）電磁溢流閥原理上，一般是由先導(dǎo)式溢流閥加上一個(gè)2位2通電磁閥組成。
2）這個(gè)電磁閥實(shí)際上由兩部分組成：2位2通的液壓閥部分，加上一個(gè)電磁鐵。2位2通閥是開(kāi)通，還是關(guān)閉，是由電磁鐵推動(dòng)閥芯運(yùn)動(dòng)來(lái)實(shí)現(xiàn)的。像樓上朋友講的，有的閥電磁鐵通電時(shí)打開(kāi)，有的閥電磁鐵斷電時(shí)打開(kāi)，蘿目青菜個(gè)人各愛(ài)（根據(jù)系統(tǒng)要求選擇）。也就是說(shuō)，電磁閥這里有一條通路一頭與先導(dǎo)溢流閥的某個(gè)部位相連，另一頭通過(guò)油管與油箱相連。通過(guò)操作電磁鐵可以讓先導(dǎo)溢流閥的某個(gè)部位或者與油箱相通，或者不與油箱相通。
3）先導(dǎo)溢流閥的主閥上腔壓力，是由先導(dǎo)閥加于控制的。如果先導(dǎo)閥正常工作，即主閥上腔有先導(dǎo)閥規(guī)定的壓力，則整個(gè)溢流閥就會(huì)在系統(tǒng)壓力到達(dá)調(diào)定壓力時(shí)其主閥口打開(kāi)一定的開(kāi)度，一方面能將系統(tǒng)多余流量流回油箱，另一方面又能維持系統(tǒng)的壓力為先導(dǎo)閥的調(diào)定值?？梢?jiàn)，先導(dǎo)閥主要管壓力，主閥服從先導(dǎo)閥的，在先導(dǎo)閥動(dòng)作時(shí)將主閥口開(kāi)到合適大小，正好將多余流量流出去，又不影響系統(tǒng)壓力。
