電動閥門的特性
| 電動閥門動作(zuo)力距比電動閥門大(da)，電動閥(fa)門開關(guan)動(dong)作速度可以調整，結構(gou)簡單，易(yi)維護(hu)，動(dong)作過程中因(yin)氣體(ti)本(ben)身的(de)緩沖特性，不易(yi)因(yin)卡住而損壞，但(dan)必須(xu)有氣源，且(qie)其控制(zhi)系統也比(bi)電動(dong)閥門復雜。 氣動(dong)(dong)閥(fa)門響應靈(ling)敏，安全可靠，很多對控制(zhi)要求高(gao)的(de)廠專為(wei)氣動(dong)(dong)儀表控制(zhi)元件設置(zhi)壓縮空(kong)氣站。電(dian)動(dong)(dong)的(de)就是要電(dian)。并能控制(zhi)其流量的(de)裝置(zhi)。 一(yi)，什么是(shi)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)閥(fa)(fa)：電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)閥(fa)(fa)簡單地說(shuo)就是(shi)用電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)執(zhi)行(xing)(xing)(xing)器(qi)控制閥(fa)(fa)門,從而實(shi)現閥(fa)(fa)門的(de)開和關。其可分為上(shang)下兩部分，上(shang)半(ban)部分為電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)執(zhi)行(xing)(xing)(xing)器(qi)，下半(ban)部分為閥(fa)(fa)門。電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)閥(fa)(fa)分兩種(zhong)，一(yi)種(zhong)為角行(xing)(xing)(xing)程電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)閥(fa)(fa)：由角行(xing)(xing)(xing)程的(de)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)執(zhi)行(xing)(xing)(xing)器(qi)配(pei)合角行(xing)(xing)(xing)程的(de)閥(fa)(fa)使(shi)(shi)用，實(shi)現閥(fa)(fa)門90度(du)以內旋控制管道流(liu)體(ti)通斷；另一(yi)種(zhong)為直行(xing)(xing)(xing)程電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)閥(fa)(fa)：由直行(xing)(xing)(xing)程的(de)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)執(zhi)行(xing)(xing)(xing)器(qi)配(pei)合直行(xing)(xing)(xing)程的(de)閥(fa)(fa)使(shi)(shi)用，實(shi)現閥(fa)(fa)板上(shang)下動(dong)(dong)(dong)作控制管道流(liu)體(ti)通斷。通常在(zai)自動(dong)(dong)(dong)化程度(du)較高的(de)設(she)備上(shang)配(pei)套(tao)使(shi)(shi)用。 二，電(dian)動(dong)閥操作原(yuan)理：電(dian)動(dong)閥通常(chang)由(you)電(dian)動(dong)執行機(ji)構和(he)閥門連接起來，經過(guo)安(an)裝調試后成為電(dian)動(dong)閥。電(dian)動閥門使用電能作為動力來接通電動執行(xing)機(ji)構驅動閥門(men)，實現閥門(men)的(de)(de)(de)開關、調(diao)節動作。從而達到對管道介質的(de)(de)(de)開關或是調(diao)節目的(de)(de)(de)。 |
