關于(yu)上述環(huan)境中的(de)(de)電(dian)(dian)(dian)(dian)動(dong)(dong)球閥(fa)(fa)，蝸(gua)輪法(fa)蘭(lan)(lan)球閥(fa)(fa)其電(dian)(dian)(dian)(dian)動(dong)(dong)安(an)裝(zhuang)(zhuang)(zhuang)構造、資料和(he)防護方式(shi)皆不同(tong)。因而(er)(er)，應根據上述義務環(huan)境選擇相應的(de)(de)閥(fa)(fa)門(men)電(dian)(dian)(dian)(dian)動(dong)(dong)安(an)裝(zhuang)(zhuang)(zhuang)。根據工(gong)程控制要求，對電(dian)(dian)(dian)(dian)動(dong)(dong)球閥(fa)(fa)來講(jiang)，其控制功用(yong)(yong)是由(you)電(dian)(dian)(dian)(dian)動(dong)(dong)安(an)裝(zhuang)(zhuang)(zhuang)來完成的(de)(de)。使用(yong)(yong)電(dian)(dian)(dian)(dian)動(dong)(dong)球閥(fa)(fa)的(de)(de)主旨(zhi)，就是對閥(fa)(fa)門(men)的(de)(de)開、手動(dong)(dong)法(fa)蘭(lan)(lan)球閥(fa)(fa)閉(bi)以(yi)(yi)及調理聯動(dong)(dong)完成非人工(gong)的(de)(de)電(dian)(dian)(dian)(dian)氣控制或(huo)計(ji)算機(ji)控制。電(dian)(dian)(dian)(dian)動(dong)(dong)安(an)裝(zhuang)(zhuang)(zhuang)使用(yong)(yong)已(yi)不只(zhi)是爲了節儉人力了。由(you)于(yu)不同(tong)廠家商(shang)品(pin)的(de)(de)功用(yong)(yong)和(he)質量區別較(jiao)大，因而(er)(er)，法(fa)蘭(lan)(lan)固定式(shi)球閥(fa)(fa)選擇電(dian)(dian)(dian)(dian)動(dong)(dong)安(an)裝(zhuang)(zhuang)(zhuang)和(he)選擇所配閥(fa)(fa)門(men)對工(gong)程同(tong)等重要。蝸(gua)輪法(fa)蘭(lan)(lan)球閥(fa)(fa)由(you)于(yu)工(gong)業自動(dong)(dong)化程度的(de)(de)要求一直進步，一方面(mian)對電(dian)(dian)(dian)(dian)動(dong)(dong)閥(fa)(fa)門(men)的(de)(de)使用(yong)(yong)量越來越多，另一方面(mian)對電(dian)(dian)(dian)(dian)動(dong)(dong)閥(fa)(fa)門(men)的(de)(de)控制要求也越來越高，越來越復雜。所以(yi)(yi)電(dian)(dian)(dian)(dian)動(dong)(dong)閥(fa)(fa)門(men)在電(dian)(dian)(dian)(dian)氣控制方面(mian)的(de)(de)設計(ji)也在一直更新(xin)。
