【電動(dong)蝶(die)閥(fa)】電動(dong)蝶(die)閥(fa)規(gui)格型號 電動(dong)蝶(die)閥(fa)和氣動(dong)蝶(die)閥(fa)的區(qu)別
電動蝶閥規格型號
電(dian)動蝶閥規格型號很(hen)多,根據口徑,壓力,材質,結構形式,連接方式,使用介質的不同,型號也會承現(xian)不同,比如我們經(jing)常生(sheng)產的有D943H-16C DN300 D943X-10C DN250 D941X-10 DN100,D973H-25C DN600 D971X-10 DN400等(deng)。
電動蝶閥和氣動蝶閥的區別
電動蝶閥概述:
屬于電動閥門和(he)電(dian)(dian)(dian)動調節(jie)閥(fa)(fa)中的一(yi)個品種。電(dian)(dian)(dian)動蝶(die)閥(fa)(fa)銜接方(fang)法主(zhu)要有(you):法蘭式和(he)對夾(jia)式;電(dian)(dian)(dian)動蝶(die)閥(fa)(fa)密封情勢主(zhu)要有(you):橡膠(jiao)密封和(he)金屬密封。電(dian)(dian)(dian)動蝶(die)閥(fa)(fa)顛末過(guo)程電(dian)(dian)(dian)源(yuan)旌旗(qi)燈(deng)號來節(jie)制(zhi)蝶(die)閥(fa)(fa)的開關。該產物可用(yong)做管道體(ti)系的堵截(jie)閥(fa)(fa),節(jie)制(zhi)閥(fa)(fa)和(he)止回閥(fa)(fa)。附帶手動節(jie)制(zhi)裝(zhuang)配,一(yi)旦呈現電(dian)(dian)(dian)源(yuan)差錯,能夠或者(zhe)或者(zhe)暫(zan)時用(yong)手動操縱,不至(zhi)于(yu)影響應用(yong)。
電動蝶閥工作原理:
工(gong)作(zuo)電(dian)源通(tong)常有:AC220V,AC380V等(deng)(deng)。輸入信號(hao):4~20mA 0~10v等(deng)(deng)弱(ruo)電(dian)信號(hao)。由調節型電(dian)動(dong)執(zhi)行器和(he)(he)閥桿銜接調試好以后;以電(dian)能作(zuo)為驅(qu)動(dong)力(li)來驅(qu)動(dong)蝶閥閥板,作(zuo)0~90°部分反(fan)轉回轉運動(dong)。接收工(gong)業自動(dong)化控(kong)制系統的4~20mA信號(hao)來精確控(kong)制閥門開關度,從而達(da)到流量、溫度、壓力(li)等(deng)(deng)不同需求參(can)數的調節和(he)(he)控(kong)制。
氣動蝶閥概述:
氣(qi)動(dong)(dong)蝶閥(fa)(fa)(fa)是(shi)由氣(qi)動(dong)(dong)履行(xing)器和蝶閥(fa)(fa)(fa)構成。氣(qi)動(dong)(dong)蝶閥(fa)(fa)(fa)是(shi)用(yong)隨閥(fa)(fa)(fa)桿遷移轉(zhuan)變的圓形蝶板(ban)做啟(qi)閉性,以完成啟(qi)用(yong)舉措的氣(qi)動(dong)(dong)閥(fa)(fa)(fa)門主要做截斷(duan)閥(fa)(fa)(fa)應(ying)用(yong),亦可計劃成具備調理或段閥(fa)(fa)(fa)兼調理的功效,今朝蝶閥(fa)(fa)(fa)在高壓大(da)中(zhong)口徑管道上的應(ying)用(yong)越來越多。氣(qi)動(dong)(dong)蝶閥(fa)(fa)(fa)分類(lei):不銹鋼(gang)氣(qi)動(dong)(dong)蝶閥(fa)(fa)(fa),硬密(mi)封氣(qi)動(dong)(dong)蝶閥(fa)(fa)(fa)軟密(mi)封氣(qi)動(dong)(dong)蝶閥(fa)(fa)(fa),碳(tan)鋼(gang)氣(qi)動(dong)(dong)蝶閥(fa)(fa)(fa)。
氣動蝶閥工作原理:
由氣動(dong)(dong)(dong)執(zhi)行(xing)機(ji)構(gou)和蝶(die)閥連接(jie)組成(cheng),氣動(dong)(dong)(dong)蝶(die)閥是通過(guo)壓(ya)縮空氣進入氣動(dong)(dong)(dong)執(zhi)行(xing)機(ji)構(gou)驅動(dong)(dong)(dong)執(zhi)行(xing)器帶動(dong)(dong)(dong)圓型的(de)蝶(die)板做90°旋轉運動(dong)(dong)(dong),來作(zuo)為(wei)(wei)(wei)管道開關(guan)和調節流量使用。氣動(dong)(dong)(dong)蝶(die)閥是通過(guo)0-90度的(de)啟閉(bi)作(zuo)為(wei)(wei)(wei)工作(zuo)原理。即為(wei)(wei)(wei)0度為(wei)(wei)(wei)全(quan)關(guan)狀態(tai),90度為(wei)(wei)(wei)全(quan)啟狀態(tai)。在氣動(dong)(dong)(dong)執(zhi)行(xing)器上添加定位器,輸入相應的(de)信(xin)號(hao),可對(dui)蝶(die)閥碟版進行(xing)0-90度的(de)任意調節。
氣動對夾蝶閥
執行器對比:
執(zhi)(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)(qi)(qi)是自(zi)動(dong)(dong)化(hua)技術工具中接收控制信息并對(dui)受控對(dui)象施加控制作(zuo)用的裝置。執(zhi)(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)(qi)(qi)按所用驅動(dong)(dong)能源分(fen)為(wei)氣動(dong)(dong)、電(dian)動(dong)(dong)和液(ye)壓執(zhi)(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)(qi)(qi)三種,電(dian)動(dong)(dong)執(zhi)(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)(qi)(qi)與氣動(dong)(dong)執(zhi)(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)(qi)(qi)是為(wei)目(mu)前的主流執(zhi)(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)(qi)(qi)。我們貫(guan)良閥門就為(wei)大家分(fen)析電(dian)動(dong)(dong)執(zhi)(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)(qi)(qi)與氣動(dong)(dong)執(zhi)(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)(qi)(qi)之間(jian)的比較。
我們主要(yao)從初始費(fei)用、操作(zuo)(zuo)(zuo)、性能(neng)、標度(du)、動(dong)作(zuo)(zuo)(zuo)速度(du)、抗腐蝕、操作(zuo)(zuo)(zuo)安全(quan)性、維修、故障安全(quan)性售后保證(zheng),維護,手動(dong)操作(zuo)(zuo)(zuo)這些方面來(lai)展(zhan)開全(quan)面的比較。
從費用上來說,氣動執(zhi)行(xing)器(qi)價格相對(dui)低(di)廉,電動執(zhi)行(xing)器(qi)則相對(dui)貴些,這(zhe)樣可以減少了氣動工(gong)程的造(zao)價
操(cao)作上電動執行(xing)器很難(nan)改變行(xing)程,而氣動則是(shi)采用模塊化,允許(xu)調(diao)節或數字控制(zhi)。
性能上(shang)氣動(dong)適應頻繁滿(man)負載(zai)動(dong)作(zuo),電動(dong)受電動(dong)機帶載(zai)能力和(he)每小時最多(duo)啟動(dong)數量限制。氣動(dong)執(zhi)行器工作(zuo)周(zhou)期(qi)長,保(bao)證2百萬次左右動(dong)作(zuo)。氣動(dong)執(zhi)行器可以精確可重復控制,0.25%精度。
標(biao)度上電(dian)動(dong)(dong)執(zhi)(zhi)行器(qi)較為復雜(za),電(dian)動(dong)(dong)執(zhi)(zhi)行器(qi)上力(li)矩開關,限制開關,在安裝上非常(chang)復雜(za),需要專業(ye)人士(shi)。
動(dong)作速(su)(su)度上講氣動(dong)可以做出調整,電(dian)動(dong)執(zhi)行器(qi)是(shi)固定的。閥門的開關速(su)(su)度可獨立設定。
抗腐蝕:氣動執(zhi)行(xing)器(qi)(qi)采(cai)用內部、外(wai)部環氧涂(tu)層(ceng),電動執(zhi)行(xing)器(qi)(qi)采(cai)用外(wai)部標準噴漆,電動執(zhi)行(xing)器(qi)(qi)進水會導致構件的損(sun)壞。
操作安全性,氣動執行(xing)器不需要(yao)電(dian)(dian)源(yuan),而(er)電(dian)(dian)動執行(xing)器一般(ban)是采用220V或者3相電(dian)(dian)380V電(dian)(dian)源(yuan)。可以說明電(dian)(dian)動執行(xing)器在潮濕工作的環境中危險系數大些,氣動則不受影響。
在維修(xiu)上,氣(qi)動執行(xing)器簡(jian)單,因(yin)為(wei)只(zhi)有一個運動的部(bu)(bu)件,而電動執行(xing)器的部(bu)(bu)件比較多,要專業的人士才(cai)維修(xiu)。
售后(hou)保證上任何執行器(qi)不正常工(gong)作,可(ke)以再無(wu)電源或氣源情況下(xia)修理(li)或更換(huan)。在維(wei)護上,氣動(dong)執行器(qi)可(ke)以不需要油(you)脂,
電動(dong)執行器需(xu)要(yao)大量的油脂。手動(dong)操作上,失(shi)去了(le)電源都可以實現手動(dong)操作。
目前電動執行器(qi)時(shi)我們(men)主流的(de)執行器(qi)而氣動執行器(qi)也不會被淘汰。都有著自己的(de)優勢與缺點。
