單(dan)(dan)向(xiang)(xiang)(xiang)閥(fa)有(you)直通式和(he)直角式兩種(zhong)(zhong)。直通式單(dan)(dan)向(xiang)(xiang)(xiang)閥(fa)用(yong)(yong)(yong)螺紋(wen)連接安裝在(zai)(zai)(zai)管(guan)路(lu)(lu)上。直角式單(dan)(dan)向(xiang)(xiang)(xiang)閥(fa)有(you)螺紋(wen)連接、板式連接和(he)法(fa)蘭連接三種(zhong)(zhong)形(xing)式。液控(kong)單(dan)(dan)向(xiang)(xiang)(xiang)閥(fa)也稱閉鎖閥(fa)或保壓(ya)(ya)閥(fa),它與(yu)單(dan)(dan)向(xiang)(xiang)(xiang)閥(fa)相同,用(yong)(yong)(yong)以防止(zhi)油(you)(you)(you)(you)液反向(xiang)(xiang)(xiang)流(liu)(liu)動(dong)。但在(zai)(zai)(zai)液壓(ya)(ya)回路(lu)(lu)中(zhong)需要(yao)油(you)(you)(you)(you)流(liu)(liu)反向(xiang)(xiang)(xiang)流(liu)(liu)動(dong)時又可(ke)(ke)利用(yong)(yong)(yong)控(kong)制(zhi)油(you)(you)(you)(you)壓(ya)(ya),打開單(dan)(dan)向(xiang)(xiang)(xiang)閥(fa),使油(you)(you)(you)(you)流(liu)(liu)在(zai)(zai)(zai)兩個方向(xiang)(xiang)(xiang)都(dou)可(ke)(ke)流(liu)(liu)動(dong)。液控(kong)單(dan)(dan)向(xiang)(xiang)(xiang)閥(fa)采(cai)用(yong)(yong)(yong)錐形(xing)閥(fa)芯,因(yin)此密封性(xing)能(neng)好。在(zai)(zai)(zai)要(yao)求封閉油(you)(you)(you)(you)路(lu)(lu)時,可(ke)(ke)用(yong)(yong)(yong)此閥(fa)作(zuo)為油(you)(you)(you)(you)路(lu)(lu)的單(dan)(dan)向(xiang)(xiang)(xiang)鎖緊(jin)而起(qi)保壓(ya)(ya)作(zuo)用(yong)(yong)(yong)。液控(kong)單(dan)(dan)向(xiang)(xiang)(xiang)閥(fa)控(kong)制(zhi)油(you)(you)(you)(you)的泄漏方式有(you)內泄式和(he)外泄式二種(zhong)(zhong)。在(zai)(zai)(zai)油(you)(you)(you)(you)流(liu)(liu)反向(xiang)(xiang)(xiang)出口無背壓(ya)(ya)的油(you)(you)(you)(you)路(lu)(lu)中(zhong)可(ke)(ke)用(yong)(yong)(yong)內泄式;否則需用(yong)(yong)(yong)外泄式,以降低控(kong)制(zhi)油(you)(you)(you)(you)壓(ya)(ya)力。

單(dan)(dan)向(xiang)(xiang)閥(fa)(fa)是氣(qi)流(liu)(liu)(liu)只能一個(ge)方向(xiang)(xiang)流(liu)(liu)(liu)動而不(bu)能反向(xiang)(xiang)流(liu)(liu)(liu)動的(de)方向(xiang)(xiang)控制閥(fa)(fa)。其工作原理與(yu)液壓(ya)(ya)(ya)單(dan)(dan)向(xiang)(xiang)閥(fa)(fa)一樣。壓(ya)(ya)(ya)縮空(kong)氣(qi)從(cong)(cong)P口(kou)(kou)進入,克服彈簧(huang)力和摩擦力使(shi)單(dan)(dan)向(xiang)(xiang)閥(fa)(fa)閥(fa)(fa)口(kou)(kou)開啟,壓(ya)(ya)(ya)縮空(kong)氣(qi)從(cong)(cong)P流(liu)(liu)(liu)至A;當P口(kou)(kou)無壓(ya)(ya)(ya)縮空(kong)氣(qi)時,在彈簧(huang)力和A口(kou)(kou)(腔(qiang))余氣(qi)力作用下;閥(fa)(fa)口(kou)(kou)處于關閉狀 態,使(shi)從(cong)(cong)A至P氣(qi)流(liu)(liu)(liu)不(bu)通。單(dan)(dan)向(xiang)(xiang)閥(fa)(fa)應用于不(bu)允許氣(qi)流(liu)(liu)(liu)反向(xiang)(xiang)流(liu)(liu)(liu)動的(de)場(chang)合(he),如(ru)空(kong)壓(ya)(ya)(ya)機(ji)向(xiang)(xiang)氣(qi)罐充氣(qi) 時,在空(kong)壓(ya)(ya)(ya)機(ji)與(yu)氣(qi)罐之間設置一單(dan)(dan)向(xiang)(xiang)閥(fa)(fa),當空(kong)壓(ya)(ya)(ya)機(ji)停止(zhi)工作時,可(ke)防止(zhi)氣(qi)罐中的(de)壓(ya)(ya)(ya)縮空(kong)氣(qi)回流(liu)(liu)(liu) 到(dao)空(kong)壓(ya)(ya)(ya)機(ji)。單(dan)(dan)向(xiang)(xiang)閥(fa)(fa)還常與(yu)節流(liu)(liu)(liu)閥(fa)(fa)、順(shun)序(xu)閥(fa)(fa)等組合(he)成(cheng)單(dan)(dan)向(xiang)(xiang)節流(liu)(liu)(liu)閥(fa)(fa)、單(dan)(dan)向(xiang)(xiang)順(shun)序(xu)閥(fa)(fa)使(shi)用。
