單向閥又稱止回閥或逆止閥。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。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(dòng)。但在液壓回路中需要油流反向流動(dòng)時(shí)又可利用控制油壓，打開單向閥，使油流在兩個(gè)方向都可流動(dòng)。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(shí)，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。

單向閥的作用
（1）普通單向閥的作用是使油液只能沿著一個(gè)方向流動(dòng),不允許反向倒流.
（2）它的用途是：安裝在泵的出口,可防止系統(tǒng)壓力沖擊對(duì)泵的影響,另外,泵不工作時(shí),可防止系統(tǒng)油液經(jīng)泵倒流回油箱,單向閥還可用來分隔油路,防止干擾.單向閥與其他閥組合便可組成復(fù)合閥.單向閥與其他閥可組成液控復(fù)合閥
（3）對(duì)于普通液控單向閥,當(dāng)控制口無控制壓力時(shí),其作用與普通單向閥一樣；當(dāng)控制口有控制壓力時(shí),通油口接通,油液便可在兩個(gè)方向自由流動(dòng).
（4）它的主要用途是：可對(duì)液壓缸進(jìn)行鎖閉；作立式液壓缸的支承閥；起保壓作用.

單向閥是氣流只能一個(gè)方向流動(dòng)而不能反向流動(dòng)的方向控制閥。其工作原理與液壓?jiǎn)蜗蜷y一樣。壓縮空氣從P口進(jìn)入，克服彈簧力和摩擦力使單向閥閥口開啟，壓縮空氣從P流至A；當(dāng)P口無壓縮空氣時(shí)，在彈簧力和A口(腔)余氣力作用下；閥口處于關(guān)閉狀 態(tài)，使從A至P氣流不通。單向閥應(yīng)用于不允許氣流反向流動(dòng)的場(chǎng)合，如空壓機(jī)向氣罐充氣 時(shí)，在空壓機(jī)與氣罐之間設(shè)置一單向閥，當(dāng)空壓機(jī)停止工作時(shí)，可防止氣罐中的壓縮空氣回流 到空壓機(jī)。單向閥還常與節(jié)流閥、順序閥等組合成單向節(jié)流閥、單向順序閥使用。

原裝Z2FS6B2-4X/2QV現(xiàn)貨銷售專業(yè)經(jīng)營(yíng)LED照明燈具的制造企業(yè)已經(jīng)有幾千家，但是在市場(chǎng)終端，專業(yè)從事LED產(chǎn)品經(jīng)營(yíng)的商家卻寥寥無幾，LED專賣店在市場(chǎng)上也較為少見。不過，筆者在一些賣場(chǎng)看到，經(jīng)營(yíng)LED產(chǎn)品的店面呈現(xiàn)不規(guī)范、非統(tǒng)無標(biāo)準(zhǔn)的形象和運(yùn)作機(jī)制，很多個(gè)品牌扎堆擺放，給消費(fèi)者較為零亂的形象。消費(fèi)者認(rèn)識(shí)不到位經(jīng)銷商和導(dǎo)購(gòu)培訓(xùn)非常必要傳統(tǒng)燈具技術(shù)含量低，導(dǎo)購(gòu)員很容易將產(chǎn)品功能、特點(diǎn)、使用方法等清晰明了地傳達(dá)給消費(fèi)者。而由于LED產(chǎn)品的特殊性，目前，很多廠家老板、業(yè)務(wù)員對(duì)LED相關(guān)的技術(shù)、產(chǎn)品特性都處于一知半解的狀態(tài)，更別說對(duì)商家、導(dǎo)購(gòu)員進(jìn)行相應(yīng)的培訓(xùn)了，導(dǎo)致導(dǎo)購(gòu)員面對(duì)消費(fèi)者的提問也顯得很尷尬，當(dāng)然銷量就無法提升了。
