【電動(dong)(dong)蝶閥(fa)】電動(dong)(dong)蝶閥(fa)規格型號(hao) 電動(dong)(dong)蝶閥(fa)和氣(qi)動(dong)(dong)蝶閥(fa)的區別

電動蝶閥規格型號

電動蝶閥(fa)規格型(xing)號很(hen)多，根據口(kou)徑，壓力，材質，結構形式，連接方式，使(shi)用介質的不同，型(xing)號也會(hui)承現不同，比如我(wo)們經常生產的有D943H-16C DN300 D943X-10C DN250 D941X-10 DN100，D973H-25C DN600 D971X-10 DN400等。

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)電動(dong)調節閥中的(de)一個品種。電動(dong)蝶(die)(die)閥銜接方法主(zhu)要有(you)：法蘭式(shi)和(he)對夾(jia)式(shi)；電動(dong)蝶(die)(die)閥密封(feng)情勢主(zhu)要有(you)：橡膠(jiao)密封(feng)和(he)金屬(shu)密封(feng)。電動(dong)蝶(die)(die)閥顛末過程(cheng)電源(yuan)旌(jing)旗燈號(hao)來節制蝶(die)(die)閥的(de)開關。該產物可用(yong)做管道體系的(de)堵截閥，節制閥和(he)止回(hui)閥。附帶手動(dong)節制裝(zhuang)配，一旦呈(cheng)現電源(yuan)差錯，能(neng)夠或(huo)(huo)者或(huo)(huo)者暫時用(yong)手動(dong)操縱，不至于(yu)影響應用(yong)。

電動蝶閥工作原理：

工作(zuo)電源通常(chang)有：AC220V，AC380V等。輸入信(xin)(xin)號(hao)：4~20mA 0~10v等弱(ruo)電信(xin)(xin)號(hao)。由調(diao)(diao)節型電動(dong)執行器和閥桿(gan)銜(xian)接(jie)調(diao)(diao)試好以(yi)后；以(yi)電能作(zuo)為驅(qu)動(dong)力(li)來(lai)驅(qu)動(dong)蝶閥閥板，作(zuo)0~90°部分反轉回轉運動(dong)。接(jie)收工業自動(dong)化控制(zhi)系統的(de)(de)4~20mA信(xin)(xin)號(hao)來(lai)精確控制(zhi)閥門開關度，從而達到流量、溫度、壓力(li)等不同需(xu)求參數的(de)(de)調(diao)(diao)節和控制(zhi)。

氣動蝶閥概述：

氣(qi)(qi)(qi)(qi)(qi)動(dong)蝶(die)(die)(die)(die)(die)閥(fa)是(shi)(shi)由(you)氣(qi)(qi)(qi)(qi)(qi)動(dong)履行器和蝶(die)(die)(die)(die)(die)閥(fa)構成。氣(qi)(qi)(qi)(qi)(qi)動(dong)蝶(die)(die)(die)(die)(die)閥(fa)是(shi)(shi)用隨閥(fa)桿遷(qian)移轉(zhuan)變的圓(yuan)形蝶(die)(die)(die)(die)(die)板做啟(qi)閉性，以完成啟(qi)用舉(ju)措的氣(qi)(qi)(qi)(qi)(qi)動(dong)閥(fa)門主要做截(jie)斷閥(fa)應(ying)用，亦(yi)可計劃(hua)成具備調理或段閥(fa)兼調理的功效，今朝蝶(die)(die)(die)(die)(die)閥(fa)在高(gao)壓大中口(kou)徑管道上(shang)的應(ying)用越來越多。氣(qi)(qi)(qi)(qi)(qi)動(dong)蝶(die)(die)(die)(die)(die)閥(fa)分類：不(bu)銹(xiu)鋼氣(qi)(qi)(qi)(qi)(qi)動(dong)蝶(die)(die)(die)(die)(die)閥(fa)，硬密(mi)封氣(qi)(qi)(qi)(qi)(qi)動(dong)蝶(die)(die)(die)(die)(die)閥(fa)軟密(mi)封氣(qi)(qi)(qi)(qi)(qi)動(dong)蝶(die)(die)(die)(die)(die)閥(fa)，碳鋼氣(qi)(qi)(qi)(qi)(qi)動(dong)蝶(die)(die)(die)(die)(die)閥(fa)。

氣動蝶閥工作原理：

由(you)氣(qi)(qi)動(dong)(dong)執(zhi)行機(ji)構(gou)和(he)(he)蝶(die)閥連接組成，氣(qi)(qi)動(dong)(dong)蝶(die)閥是通過壓縮空氣(qi)(qi)進入氣(qi)(qi)動(dong)(dong)執(zhi)行機(ji)構(gou)驅動(dong)(dong)執(zhi)行器帶動(dong)(dong)圓型的(de)(de)蝶(die)板做90°旋轉運動(dong)(dong)，來(lai)作為管道(dao)開關和(he)(he)調(diao)節(jie)(jie)流量(liang)使用。氣(qi)(qi)動(dong)(dong)蝶(die)閥是通過0-90度(du)的(de)(de)啟閉作為工作原理(li)。即為0度(du)為全(quan)(quan)關狀(zhuang)態，90度(du)為全(quan)(quan)啟狀(zhuang)態。在氣(qi)(qi)動(dong)(dong)執(zhi)行器上添(tian)加定(ding)位器，輸入相應的(de)(de)信號，可(ke)對蝶(die)閥碟(die)版進行0-90度(du)的(de)(de)任意調(diao)節(jie)(jie)。

執行器對比：

執(zhi)(zhi)(zhi)行(xing)(xing)器(qi)(qi)(qi)是自(zi)動(dong)化技術工具中(zhong)接收控制信息并對受(shou)控對象施加控制作用(yong)的裝置。執(zhi)(zhi)(zhi)行(xing)(xing)器(qi)(qi)(qi)按所用(yong)驅動(dong)能源分為氣(qi)動(dong)、電動(dong)和液壓(ya)執(zhi)(zhi)(zhi)行(xing)(xing)器(qi)(qi)(qi)三種(zhong)，電動(dong)執(zhi)(zhi)(zhi)行(xing)(xing)器(qi)(qi)(qi)與氣(qi)動(dong)執(zhi)(zhi)(zhi)行(xing)(xing)器(qi)(qi)(qi)是為目前的主流(liu)執(zhi)(zhi)(zhi)行(xing)(xing)器(qi)(qi)(qi)。我(wo)們貫良閥門就(jiu)為大家分析(xi)電動(dong)執(zhi)(zhi)(zhi)行(xing)(xing)器(qi)(qi)(qi)與氣(qi)動(dong)執(zhi)(zhi)(zhi)行(xing)(xing)器(qi)(qi)(qi)之間的比(bi)較。

我們主要從初(chu)始費(fei)用(yong)、操作、性能、標度(du)、動(dong)作速度(du)、抗腐蝕、操作安全性、維修(xiu)、故(gu)障安全性售后保(bao)證，維護，手動(dong)操作這(zhe)些方面來展開全面的比較。

從費用(yong)上來說，氣(qi)動(dong)執行器價格相對(dui)低廉，電(dian)動(dong)執行器則相對(dui)貴些，這樣可(ke)以減少了氣(qi)動(dong)工程的(de)造價

操作上電動(dong)執行器很難改(gai)變(bian)行程，而氣(qi)動(dong)則是(shi)采用模塊化，允(yun)許調節或數字控(kong)制。

性能上氣(qi)動(dong)適應(ying)頻繁滿負載動(dong)作(zuo)，電(dian)動(dong)受電(dian)動(dong)機帶載能力和每小時最多啟(qi)動(dong)數量限(xian)制。氣(qi)動(dong)執行器工作(zuo)周期(qi)長，保證(zheng)2百萬次左右動(dong)作(zuo)。氣(qi)動(dong)執行器可以精確可重復控制，0.25%精度(du)。

標度上電(dian)動執行(xing)(xing)器較為復雜(za)，電(dian)動執行(xing)(xing)器上力矩開(kai)(kai)關，限(xian)制(zhi)開(kai)(kai)關，在安裝上非常復雜(za)，需要專(zhuan)業人士(shi)。

動作(zuo)速度(du)(du)上講氣動可(ke)(ke)以做出調(diao)整，電(dian)動執行器是固定(ding)的(de)。閥門的(de)開關速度(du)(du)可(ke)(ke)獨立(li)設定(ding)。

抗(kang)腐蝕：氣動(dong)執(zhi)行(xing)器(qi)采(cai)用內部、外部環氧(yang)涂層，電動(dong)執(zhi)行(xing)器(qi)采(cai)用外部標準(zhun)噴漆(qi)，電動(dong)執(zhi)行(xing)器(qi)進水會導致(zhi)構件的損壞(huai)。

操作安全(quan)性，氣(qi)動(dong)(dong)執(zhi)行(xing)(xing)器(qi)不需要電(dian)(dian)源(yuan)，而電(dian)(dian)動(dong)(dong)執(zhi)行(xing)(xing)器(qi)一般是采用(yong)220V或者3相(xiang)電(dian)(dian)380V電(dian)(dian)源(yuan)。可以說明電(dian)(dian)動(dong)(dong)執(zhi)行(xing)(xing)器(qi)在潮濕(shi)工作的(de)環境中(zhong)危險系(xi)數大些，氣(qi)動(dong)(dong)則不受影響(xiang)。

在維修(xiu)上，氣(qi)動(dong)執行器簡單(dan)，因為(wei)只(zhi)有一個運(yun)動(dong)的(de)部(bu)件，而電動(dong)執行器的(de)部(bu)件比(bi)較(jiao)多，要專業的(de)人士才維修(xiu)。

售后(hou)保(bao)證上任何執(zhi)行器不(bu)正常工作(zuo)，可以再無電源(yuan)或(huo)氣源(yuan)情況(kuang)下(xia)修(xiu)理(li)或(huo)更換(huan)。在維護(hu)上，氣動執(zhi)行器可以不(bu)需(xu)要油脂(zhi)，

電(dian)(dian)動(dong)執行器需要(yao)大量(liang)的(de)油脂。手動(dong)操(cao)作上，失去了電(dian)(dian)源(yuan)都可以實現(xian)手動(dong)操(cao)作。

目(mu)前電(dian)動執行(xing)(xing)器(qi)時我(wo)們主流的(de)執行(xing)(xing)器(qi)而氣(qi)動執行(xing)(xing)器(qi)也不會被(bei)淘汰。都有著自己的(de)優勢與缺點。
