BURKERT氣動(dong)(dong)角座(zuo)調(diao)節(jie)閥(fa)(fa)(fa)(fa)的(de)(de)(de)性(xing)(xing)能要(yao)求1.換(huan)向(xiang)(xiang)(xiang)性(xing)(xing)能:在規定的(de)(de)(de)工(gong)作條件下，電(dian)(dian)(dian)磁閥(fa)(fa)(fa)(fa)通(tong)電(dian)(dian)(dian)后(hou)能否可靠(kao)地換(huan)向(xiang)(xiang)(xiang)，斷(duan)電(dian)(dian)(dian)后(hou)能否可靠(kao)地復位。2.壓力(li)損(sun)失(shi):電(dian)(dian)(dian)控(kong)換(huan)向(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)的(de)(de)(de)壓力(li)損(sun)失(shi)由液流流過電(dian)(dian)(dian)控(kong)換(huan)向(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)的(de)(de)(de)閥(fa)(fa)(fa)(fa)口(kou)時(shi)(shi)(shi)產生的(de)(de)(de)流動(dong)(dong)損(sun)失(shi)和節(jie)流損(sun)失(shi)組成。3.內泄露(lu)量(liang):電(dian)(dian)(dian)控(kong)換(huan)向(xiang)(xiang)(xiang)閥(fa)(fa)(fa)(fa)的(de)(de)(de)內泄露(lu)量(liang)是指(zhi)(zhi)在規定的(de)(de)(de)工(gong)作條件下，處于(yu)各個不同工(gong)作位置時(shi)(shi)(shi)，從(cong)(cong)高(gao)壓腔到(dao)(dao)低壓腔的(de)(de)(de)泄露(lu)量(liang)。4.換(huan)向(xiang)(xiang)(xiang)和復位時(shi)(shi)(shi)間:從(cong)(cong)電(dian)(dian)(dian)控(kong)鐵通(tong)電(dian)(dian)(dian)到(dao)(dao)閥(fa)(fa)(fa)(fa)芯換(huan)向(xiang)(xiang)(xiang)終(zhong)止所(suo)需要(yao)的(de)(de)(de)時(shi)(shi)(shi)間，復位時(shi)(shi)(shi)間是指(zhi)(zhi)從(cong)(cong)電(dian)(dian)(dian)磁斷(duan)電(dian)(dian)(dian)到(dao)(dao)閥(fa)(fa)(fa)(fa)芯回復到(dao)(dao)初始位置所(suo)需要(yao)的(de)(de)(de)時(shi)(shi)(shi)間。5.換(huan)向(xiang)(xiang)(xiang)頻率:在單(dan)位時(shi)(shi)(shi)間內所(suo)允許的(de)(de)(de)大(da)換(huan)向(xiang)(xiang)(xiang)次(ci)數 6.使用(yong)壽命:電(dian)(dian)(dian)磁閥(fa)(fa)(fa)(fa)使用(yong)到(dao)(dao)主(zhu)(zhu)要(yao)零(ling)部(bu)件損(sun)壞，不能進行正常的(de)(de)(de)換(huan)向(xiang)(xiang)(xiang)和復位動(dong)(dong)作，或(huo)者使用(yong)到(dao)(dao)其主(zhu)(zhu)要(yao)性(xing)(xing)能指(zhi)(zhi)標明顯惡化超過了規定指(zhi)(zhi)標所(suo)經歷(li)的(de)(de)(de)換(huan)向(xiang)(xiang)(xiang)次(ci)數。

BURKERT氣動角座(zuo)調節閥(fa)(fa)利用(yong)過程本身的(de)(de)(de)壓(ya)(ya)(ya)力(li)(li)(li)或(huo)壓(ya)(ya)(ya)差來驅(qu)動控(kong)(kong)(kong)(kong)(kong)制閥(fa)(fa)動作，也可(ke)(ke)用(yong)．溫(wen)包(bao)式檢測元(yuan)件將溫(wen)度轉換為壓(ya)(ya)(ya)力(li)(li)(li)，然后(hou)(hou)驅(qu)動控(kong)(kong)(kong)(kong)(kong)制閥(fa)(fa)動作。其特點是結構(gou)簡(jian)單、操(cao)作方便，但會引起壓(ya)(ya)(ya)降(jiang)，造成出口(kou)壓(ya)(ya)(ya)力(li)(li)(li)的(de)(de)(de)非線性，通常(chang)，穩壓(ya)(ya)(ya)精度在(zai)10％一20％。帶(dai)指(zhi)揮器(qi)作用(yong)的(de)(de)(de)自(zi)力(li)(li)(li)式控(kong)(kong)(kong)(kong)(kong)制閥(fa)(fa)可(ke)(ke)適用(yong)于小壓(ya)(ya)(ya)降(jiang)和大流量的(de)(de)(de)自(zi)力(li)(li)(li)式控(kong)(kong)(kong)(kong)(kong)制場合，出口(kou)壓(ya)(ya)(ya)力(li)(li)(li)變化范圍可(ke)(ke)小于設定(ding)(ding)壓(ya)(ya)(ya)力(li)(li)(li)的(de)(de)(de)10％。控(kong)(kong)(kong)(kong)(kong)制閥(fa)(fa)具有節能(neng)功能(neng)，因此(ci)，在(zai)一些控(kong)(kong)(kong)(kong)(kong)制要(yao)(yao)求不高(gao)的(de)(de)(de)場合被(bei)廣泛應用(yong)。自(zi)力(li)(li)(li)式控(kong)(kong)(kong)(kong)(kong)制閥(fa)(fa)執(zhi)行(xing)機構(gou)膜頭的(de)(de)(de)輸(shu)入(ru)信號(hao)是控(kong)(kong)(kong)(kong)(kong)制閥(fa)(fa)前或(huo)閥(fa)(fa)后(hou)(hou)的(de)(de)(de)壓(ya)(ya)(ya)力(li)(li)(li)或(huo)閥(fa)(fa)兩端的(de)(de)(de)壓(ya)(ya)(ya)差，或(huo)經溫(wen)包(bao)轉換后(hou)(hou)的(de)(de)(de)壓(ya)(ya)(ya)力(li)(li)(li)信號(hao)。執(zhi)行(xing)機構(gou)的(de)(de)(de)結構(gou)類(lei)似(si)氣動薄膜執(zhi)行(xing)機構(gou)。控(kong)(kong)(kong)(kong)(kong)制閥(fa)(fa)對被(bei)控(kong)(kong)(kong)(kong)(kong)介(jie)質(zhi)有一定(ding)(ding)要(yao)(yao)求，例如(ru)，自(zi)力(li)(li)(li)式壓(ya)(ya)(ya)力(li)(li)(li)控(kong)(kong)(kong)(kong)(kong)制閥(fa)(fa)的(de)(de)(de)被(bei)控(kong)(kong)(kong)(kong)(kong)介(jie)質(zhi)溫(wen)度應低于某一規(gui)(gui)定(ding)(ding)值，介(jie)質(zhi)應干凈，當介(jie)質(zhi)溫(wen)度較(jiao)高(gao)時(shi)(shi)，例如(ru)，用(yong)于蒸汽(qi)或(huo)150℃以上的(de)(de)(de)液體時(shi)(shi)，應設置冷凝(ning)器(qi)，使進入(ru)執(zhi)行(xing)機構(gou)比較(jiao)器(qi)內的(de)(de)(de)介(jie)質(zhi)溫(wen)度低于規(gui)(gui)定(ding)(ding)值。
