單向閥是氣流只能一個方向流動而不能反向流動的方向控制閥。其工作原理與液壓單向閥一樣。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，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的場合，如空壓機(jī)向氣罐充氣 時，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，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。
止回閥
止回閥用途廣泛，有很多種類，下面說的是供水和熱力常用的止回閥：
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。
