單作用氣動執行器和雙作用氣動執行器的區別:
氣動球閥中單作用和雙作用指的是氣動球閥所配氣動執行器可分為單作用和雙作用。其區別在于:單作用的氣缸內有彈簧,而雙作用內沒有。因此單作用氣動執行器的價格比雙作用氣動執行器的價格要高。
單(dan)作(zuo)用氣(qi)(qi)動(dong)(dong)執(zhi)行器一(yi)般分為(wei)常開(kai)(kai)型(xing)(xing)和常閉型(xing)(xing)(常開(kai)(kai)型(xing)(xing):通(tong)氣(qi)(qi)關(guan),斷氣(qi)(qi)開(kai)(kai);常閉型(xing)(xing):通(tong)氣(qi)(qi)開(kai)(kai),斷氣(qi)(qi)關(guan)),也就是說(shuo)(shuo),在安裝之前有(you)一(yi)個(ge)設(she)(she)定(ding)(ding),設(she)(she)定(ding)(ding)其為(wei)開(kai)(kai)或者(zhe)關(guan),如(ru)果(guo)是常開(kai)(kai)的(de)(de),那就是在通(tong)氣(qi)(qi)的(de)(de)情況下氣(qi)(qi)動(dong)(dong)執(zhi)行器關(guan)閉閥門,如(ru)果(guo)氣(qi)(qi)源出現故(gu)障或者(zhe)突然停電,單(dan)作(zuo)用氣(qi)(qi)動(dong)(dong)執(zhi)行器靠彈簧自動(dong)(dong)復(fu)位為(wei)開(kai)(kai)的(de)(de)狀態,也就是說(shuo)(shuo)會回到它的(de)(de)設(she)(she)定(ding)(ding)狀態,設(she)(she)定(ding)(ding)為(wei)關(guan),則(ze)會回到關(guan)的(de)(de)狀態,一(yi)般在危(wei)險的(de)(de)工(gong)況中使用較多(duo),比如(ru)輸(shu)送可燃氣(qi)(qi)體或可燃液(ye)體,在失去氣(qi)(qi)源又出現緊急情況的(de)(de)時候,單(dan)作(zuo)用氣(qi)(qi)動(dong)(dong)執(zhi)行機(ji)構能自動(dong)(dong)復(fu)位把(ba)危(wei)險降低,而雙作(zuo)用就不(bu)能復(fu)位。
雙作(zuo)(zuo)用氣(qi)(qi)(qi)動(dong)執行器在通(tong)氣(qi)(qi)(qi)的(de)情(qing)況(kuang)下氣(qi)(qi)(qi)動(dong)執行器打開閥門,當要(yao)關(guan)閉(bi)閥門的(de)時候另外一邊通(tong)氣(qi)(qi)(qi)才(cai)能(neng)(neng)關(guan)閉(bi),雙作(zuo)(zuo)用氣(qi)(qi)(qi)動(dong)執行器是靠氣(qi)(qi)(qi)缸工作(zuo)(zuo)復位(wei)的(de),在失去氣(qi)(qi)(qi)源(yuan)的(de)時候只能(neng)(neng)保持(chi)原(yuan)位(wei)。

單電控電磁閥和雙電控電磁閥的區別:
單電控:即只有一個(ge)電(dian)(dian)(dian)磁(ci)(ci)線(xian)(xian)圈(quan)(quan),一般(ban)用在2位(wei)(wei)3通(tong)(tong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa),線(xian)(xian)圈(quan)(quan)電(dian)(dian)(dian)壓等級一般(ban)采(cai)用DC24V、AC220V等。 兩(liang)位(wei)(wei)三通(tong)(tong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)分為常(chang)閉型(xing)(xing)和常(chang)開(kai)(kai)型(xing)(xing)兩(liang)種,常(chang)閉型(xing)(xing)指線(xian)(xian)圈(quan)(quan)沒通(tong)(tong)電(dian)(dian)(dian)時(shi)氣(qi)路(lu)是(shi)斷(duan)的,常(chang)開(kai)(kai)型(xing)(xing)指線(xian)(xian)圈(quan)(quan)沒通(tong)(tong)電(dian)(dian)(dian)時(shi)氣(qi)路(lu)是(shi)通(tong)(tong)的。 常(chang)閉型(xing)(xing)兩(liang)位(wei)(wei)三通(tong)(tong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)動作(zuo)原(yuan)理(li)(li):給(gei)線(xian)(xian)圈(quan)(quan)通(tong)(tong)電(dian)(dian)(dian),氣(qi)路(lu)接通(tong)(tong),線(xian)(xian)圈(quan)(quan)一旦斷(duan)電(dian)(dian)(dian),氣(qi)路(lu)就會斷(duan)開(kai)(kai),這相(xiang)當于“點動"。 常(chang)開(kai)(kai)型(xing)(xing)兩(liang)位(wei)(wei)三通(tong)(tong)單電(dian)(dian)(dian)控電(dian)(dian)(dian)磁(ci)(ci)閥(fa)動作(zuo)原(yuan)理(li)(li):給(gei)線(xian)(xian)圈(quan)(quan)通(tong)(tong)電(dian)(dian)(dian),氣(qi)路(lu)斷(duan)開(kai)(kai),線(xian)(xian)圈(quan)(quan)一旦斷(duan)電(dian)(dian)(dian),氣(qi)路(lu)就會接通(tong)(tong),這也是(shi)“點動"。
雙電控:即(ji)有兩(liang)個電(dian)(dian)(dian)磁(ci)(ci)線(xian)(xian)圈(quan),一般用在(zai)兩(liang)位五通(tong)(tong)(tong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa),兩(liang)位五通(tong)(tong)(tong)雙電(dian)(dian)(dian)控電(dian)(dian)(dian)磁(ci)(ci)閥(fa)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)原理:給正(zheng)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)線(xian)(xian)圈(quan)通(tong)(tong)(tong)電(dian)(dian)(dian),則(ze)正(zheng)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)氣(qi)(qi)路(lu)接通(tong)(tong)(tong)(正(zheng)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)出氣(qi)(qi)孔(kong)有氣(qi)(qi)),即(ji)使(shi)給正(zheng)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)線(xian)(xian)圈(quan)斷(duan)電(dian)(dian)(dian)后正(zheng)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)氣(qi)(qi)路(lu)仍然(ran)是接通(tong)(tong)(tong)的,將會一直維持(chi)(chi)到給反(fan)(fan)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)線(xian)(xian)圈(quan)通(tong)(tong)(tong)電(dian)(dian)(dian)為止。 給反(fan)(fan)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)線(xian)(xian)圈(quan)通(tong)(tong)(tong)電(dian)(dian)(dian),則(ze)反(fan)(fan)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)氣(qi)(qi)路(lu)接通(tong)(tong)(tong)(反(fan)(fan)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)出氣(qi)(qi)孔(kong)有氣(qi)(qi)),即(ji)使(shi)給反(fan)(fan)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)線(xian)(xian)圈(quan)斷(duan)電(dian)(dian)(dian)后反(fan)(fan)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)氣(qi)(qi)路(lu)仍然(ran)是接通(tong)(tong)(tong)的,將會一直維持(chi)(chi)到給正(zheng)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)線(xian)(xian)圈(quan)通(tong)(tong)(tong)電(dian)(dian)(dian)為止。這相(xiang)當于“自鎖"。 基于兩(liang)位五通(tong)(tong)(tong)雙電(dian)(dian)(dian)控電(dian)(dian)(dian)磁(ci)(ci)閥(fa)的這種特性,在(zai)設計機電(dian)(dian)(dian)控制(zhi)回路(lu)或編制(zhi)PLC程(cheng)序(xu)的時候,可以(yi)讓電(dian)(dian)(dian)磁(ci)(ci)閥(fa)線(xian)(xian)圈(quan)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)1~2秒就可以(yi)了,這樣可以(yi)保(bao)護電(dian)(dian)(dian)磁(ci)(ci)閥(fa)線(xian)(xian)圈(quan)不容易損壞。
