AK系列SMC單向閥參數范圍
特點簡介:
直角(jiao)式(shi)(shi)單(dan)(dan)(dan)向(xiang)(xiang)閥有螺(luo)紋連接(jie)、板(ban)式(shi)(shi)連接(jie)和法(fa)蘭連接(jie)三種形式(shi)(shi)。液(ye)控(kong)(kong)單(dan)(dan)(dan)向(xiang)(xiang)閥也(ye)稱(cheng)閉(bi)鎖閥或保壓(ya)閥,它與單(dan)(dan)(dan)向(xiang)(xiang)閥相同,用(yong)(yong)以防(fang)止(zhi)油(you)(you)液(ye)反向(xiang)(xiang)流(liu)(liu)動(dong)。但在液(ye)壓(ya)回路(lu)中需要油(you)(you)流(liu)(liu)反向(xiang)(xiang)流(liu)(liu)動(dong)時(shi)又(you)可(ke)利用(yong)(yong)控(kong)(kong)制(zhi)(zhi)油(you)(you)壓(ya),打開(kai)單(dan)(dan)(dan)向(xiang)(xiang)閥,使油(you)(you)流(liu)(liu)在兩個方向(xiang)(xiang)都可(ke)流(liu)(liu)動(dong)。液(ye)控(kong)(kong)單(dan)(dan)(dan)向(xiang)(xiang)閥采用(yong)(yong)錐形閥芯,因此(ci)密封(feng)性(xing)能好。在要求封(feng)閉(bi)油(you)(you)路(lu)時(shi),可(ke)用(yong)(yong)此(ci)閥作(zuo)為油(you)(you)路(lu)的(de)單(dan)(dan)(dan)向(xiang)(xiang)鎖緊(jin)而(er)起保壓(ya)作(zuo)用(yong)(yong)。液(ye)控(kong)(kong)單(dan)(dan)(dan)向(xiang)(xiang)閥控(kong)(kong)制(zhi)(zhi)油(you)(you)的(de)泄(xie)漏方式(shi)(shi)有內泄(xie)式(shi)(shi)和外(wai)泄(xie)式(shi)(shi)二種。在油(you)(you)流(liu)(liu)反向(xiang)(xiang)出口無背(bei)壓(ya)的(de)油(you)(you)路(lu)中可(ke)用(yong)(yong)內泄(xie)式(shi)(shi);否則需用(yong)(yong)外(wai)泄(xie)式(shi)(shi),以降低控(kong)(kong)制(zhi)(zhi)油(you)(you)壓(ya)力。
單(dan)(dan)向(xiang)閥(fa)(fa)是流(liu)(liu)體只能(neng)沿(yan)進(jin)水口流(liu)(liu)動(dong),出水口介質卻無法回流(liu)(liu),俗稱單(dan)(dan)向(xiang)閥(fa)(fa)。單(dan)(dan)向(xiang)閥(fa)(fa)又(you)稱止回閥(fa)(fa)或逆(ni)止閥(fa)(fa)。用于液壓系(xi)統中(zhong)防(fang)(fang)止油流(liu)(liu)反向(xiang)流(liu)(liu)動(dong),或者用于氣動(dong)系(xi)統中(zhong)防(fang)(fang)止壓縮空氣逆(ni)向(xiang)流(liu)(liu)動(dong)。單(dan)(dan)向(xiang)閥(fa)(fa)有(you)直(zhi)通式(shi)(shi)和直(zhi)角(jiao)式(shi)(shi)兩種。直(zhi)通式(shi)(shi)單(dan)(dan)向(xiang)閥(fa)(fa)用螺(luo)紋(wen)連(lian)(lian)接(jie)(jie)安裝在管路上。直(zhi)角(jiao)式(shi)(shi)單(dan)(dan)向(xiang)閥(fa)(fa)有(you)螺(luo)紋(wen)連(lian)(lian)接(jie)(jie)、板式(shi)(shi)連(lian)(lian)接(jie)(jie)和法蘭(lan)連(lian)(lian)接(jie)(jie)三種形式(shi)(shi)。
安裝止(zhi)回閥時,應特別(bie)注意(yi)介質流(liu)動(dong)方向,應使介質正(zheng)常流(liu)動(dong)方向與閥體上(shang)指示的箭(jian)頭方向相一致(zhi),否則就會截斷介質的正(zheng)常流(liu)動(dong)。底閥應安裝在水泵吸水管路(lu)的底端。
止(zhi)回閥(fa)關閉時(shi),會在(zai)管路中產生水(shui)錘壓力(li),嚴重(zhong)時(shi)會導致閥(fa)門、管路或(huo)設備的損壞,尤(you)其對(dui)于大口管路或(huo)高壓管路,故應引起止(zhi)回閥(fa)選用者的高度(du)注(zhu)意。
止(zhi)回(hui)閥(fa)只供防止(zhi)各類管路(lu)或設備(bei)上流體介質逆流的單向啟(qi)閉(bi)閥(fa)。
