近(jin)年來,隨著控(kong)制技(ji)術、微電(dian)子技(ji)術、通訊技(ji)術的迅速(su)發展(zhan)(zhan),智能化控(kong)制閥產品也得到了(le)迅速(su)發展(zhan)(zhan)。智能電(dian)-氣閥門定(ding)位(控(kong)制)器、智能電(dian)動(電(dian)液)執(zhi)行(xing)機構的相繼(ji)開發及完善,為(wei)控(kong)制閥產品的智能化提供了(le)可靠的保證。
按動(dong)力劃分,控制閥(fa)(fa)分為氣(qi)動(dong)、電(dian)(dian)動(dong)、電(dian)(dian)液三種。由(you)于(yu)氣(qi)動(dong)控制閥(fa)(fa)自身的結構特(te)點,若使之實(shi)現(xian)智能(neng)化只能(neng)配用(yong)智能(neng)電(dian)(dian)-氣(qi)閥(fa)(fa)門定位(控制)器來實(shi)現(xian)。電(dian)(dian)動(dong)、電(dian)(dian)液控制閥(fa)(fa)由(you)于(yu)自身配用(yong)電(dian)(dian)源,不需(xu)外配其他附件即可實(shi)現(xian)智能(neng)控制。
我國(guo)控(kong)(kong)制(zhi)閥(fa)(fa)的(de)(de)(de)研制(zhi)是從六十年代開(kai)始的(de)(de)(de),并(bing)且只(zhi)對(dui)結(jie)構(gou)相對(dui)簡單的(de)(de)(de)氣(qi)(qi)動(dong)(dong)控(kong)(kong)制(zhi)閥(fa)(fa)進(jin)行仿制(zhi),隨著歷史的(de)(de)(de)發展(zhan),氣(qi)(qi)動(dong)(dong)控(kong)(kong)制(zhi)閥(fa)(fa)經歷了(le)(le)(le)(le)從仿制(zhi)、國(guo)家行業統一設(she)計到(dao)引進(jin)、合作、自主(zhu)開(kai)發的(de)(de)(de)過(guo)程。與此同時氣(qi)(qi)動(dong)(dong)控(kong)(kong)制(zhi)閥(fa)(fa)技術(shu)的(de)(de)(de)發展(zhan)帶(dai)動(dong)(dong)了(le)(le)(le)(le)電動(dong)(dong)控(kong)(kong)制(zhi)閥(fa)(fa)技術(shu)的(de)(de)(de)不斷發展(zhan),在電動(dong)(dong)控(kong)(kong)制(zhi)閥(fa)(fa)解決(jue)了(le)(le)(le)(le)結(jie)構(gou)復雜、可靠(kao)性低(di)的(de)(de)(de)問題以后,電動(dong)(dong)控(kong)(kong)制(zhi)閥(fa)(fa)有了(le)(le)(le)(le)快速的(de)(de)(de)發展(zhan)。從簡單模(mo)擬技術(shu)發展(zhan)到(dao)現在的(de)(de)(de)微(wei)電子技術(shu)、通訊技術(shu)在氣(qi)(qi)動(dong)(dong)、電動(dong)(dong)控(kong)(kong)制(zhi)閥(fa)(fa)技術(shu)上的(de)(de)(de)成功應用,為控(kong)(kong)制(zhi)閥(fa)(fa)從模(mo)擬到(dao)智(zhi)能跨越鋪(pu)平了(le)(le)(le)(le)道路。
