FESTO電磁閥上的外導氣源口是怎樣的

FESTO電磁閥上的外導氣源口是怎樣的
FESTO電磁閥的要求不是很高，也不會作動幾次，而且FESTO的電磁閥種類比較多，般國內電磁閥是沒有那么多的，可以考慮MAC的電磁閥，他們品種比較全，而且是做電磁閥的
FESTO電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)使用(yong)(yong)(yong)特別安全，尤其適用(yong)(yong)(yong)于(yu)腐(fu)蝕(shi)性、有毒或高低(di)溫的(de)(de)介(jie)質。 FESTO電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)的(de)(de)用(yong)(yong)(yong)途電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)用(yong)(yong)(yong)于(yu)液(ye)體(ti)和氣體(ti)管路(lu)的(de)(de)開關控制(zhi)(zhi)，是(shi)兩位DO控制(zhi)(zhi)。般用(yong)(yong)(yong)于(yu)小(xiao)(xiao)(xiao)型管道的(de)(de)控制(zhi)(zhi)。電(dian)(dian)動(dong)(dong)閥(fa)用(yong)(yong)(yong)于(yu)液(ye)體(ti)、氣體(ti)和風系(xi)(xi)統(tong)管道介(jie)質流量(liang)的(de)(de)模(mo)擬量(liang)調(diao)節，是(shi)AI控制(zhi)(zhi)。在大型閥(fa)門和風系(xi)(xi)統(tong)的(de)(de)控制(zhi)(zhi)中也可(ke)以(yi)用(yong)(yong)(yong)電(dian)(dian)動(dong)(dong)閥(fa)做(zuo)兩位開關控制(zhi)(zhi)。電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)只(zhi)能用(yong)(yong)(yong)作(zuo)(zuo)開關量(liang)，是(shi)DO控制(zhi)(zhi)，只(zhi)能用(yong)(yong)(yong)于(yu)小(xiao)(xiao)(xiao)管道控制(zhi)(zhi)，常見于(yu)DN50及以(yi)下管道，往上(shang)就(jiu)很(hen)少了。電(dian)(dian)動(dong)(dong)閥(fa)可(ke)以(yi)有AI反饋信號，可(ke)以(yi)由DO或AO控制(zhi)(zhi)，比(bi)(bi)較見于(yu)大管道和風閥(fa)等。1.開關形式電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)通(tong)過線圈驅動(dong)(dong)，只(zhi)能開或關，開關時動(dong)(dong)作(zuo)(zuo)時間(jian)短(duan)。電(dian)(dian)動(dong)(dong)閥(fa)的(de)(de)驅動(dong)(dong)般是(shi)用(yong)(yong)(yong)電(dian)(dian)機，開或關動(dong)(dong)作(zuo)(zuo)完成需要定的(de)(de)時間(jian)模(mo)擬量(liang)的(de)(de)，可(ke)以(yi)做(zuo)調(diao)節。2.工作(zuo)(zuo)性質電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)般流通(tong)系(xi)(xi)數很(hen)小(xiao)(xiao)(xiao)，而且工作(zuo)(zuo)壓力差很(hen)小(xiao)(xiao)(xiao)。比(bi)(bi)如般25口徑(jing)的(de)(de)電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)流通(tong)系(xi)(xi)數比(bi)(bi)15口徑(jing)的(de)(de)電(dian)(dian)動(dong)(dong)球閥(fa)小(xiao)(xiao)(xiao)很(hen)多(duo)。
