德國力士樂節(jié)流和單向節(jié)流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。4WE6D62/EW230N9K4 4WE6D52/OFBW110RNEX 4WE6D52/BW110RNEX 4WE6D62/6EG24VN9K4
