德國力士樂REXROTH單向閥原裝
單向閥是空調冷暖機采用的，需和四通閥配合使用，一般裝在分體機外機上。單向閥其實就像一根水管，中間裝了一個單向導通的閥門。單向閥兩端都有兩個接口，一根較短的制熱毛細管和單向閥并聯(lián)，這樣兩端各有一個接口被占用。單向閥剩下的接口一端接較長的制冷毛細管，一端接室內機。正常制冷情況下，室內機是制冷，室外機是制熱，雪種由室外機流入制冷毛細管，再流入單向閥，再流入室內機，這時單向閥是導通的，制熱毛細管的流量可以忽略，不起作用。制熱情況下，工況是逆向的，室內機是制熱，室外機是制冷，這時四通閥進行換向，雪種由室內機流入單向閥，由于單向閥單向截止，雪種只能流入和單向閥并聯(lián)的制熱毛細管，再流入制冷毛細管，再流入室外機。由于室內機和室外機上面的熱交換器表面積不同，在交換角色時需要的毛細管長度不同，單向閥就是改變毛細管的長度。 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。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。但在液壓回路中需要油流反向流動時又可利用控制油壓，打開單向閥，使油流在兩個方向都可流動。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，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泄式；否則需用外泄式，以降低控制油壓力。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。壓縮空氣從尸口進入，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；閥口處于關閉狀 態(tài)，使從A至P氣流不通。單向閥應用于不允許氣流反向流動的場合，如空壓機向氣罐充氣 時，在空壓機與氣罐之間設置一單向閥，當空壓機停止工作時，可防止氣罐中的壓縮空氣回流 到空壓機。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。
