電動蝶閥規格型號
電(dian)動蝶閥規格型號很多,根據(ju)口徑,壓力,材(cai)質,結(jie)構形式(shi)(shi),連(lian)接(jie)方式(shi)(shi),使用介質的不同,型號也(ye)會(hui)承現不同,比如我們經常生產的有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:
屬于電動閥門和電(dian)(dian)動(dong)調節(jie)閥(fa)中的(de)一個品種(zhong)。電(dian)(dian)動(dong)蝶閥(fa)銜接方(fang)法主要有:法蘭式和對夾式;電(dian)(dian)動(dong)蝶閥(fa)密(mi)封情(qing)勢主要有:橡膠密(mi)封和金屬密(mi)封。電(dian)(dian)動(dong)蝶閥(fa)顛末過程電(dian)(dian)源旌旗(qi)燈(deng)號來(lai)節(jie)制蝶閥(fa)的(de)開(kai)關。該產物可用做管(guan)道體系的(de)堵截閥(fa),節(jie)制閥(fa)和止回(hui)閥(fa)。附帶手(shou)動(dong)節(jie)制裝(zhuang)配(pei),一旦(dan)呈現電(dian)(dian)源差(cha)錯,能夠或(huo)者或(huo)者暫時用手(shou)動(dong)操縱,不至于影響應(ying)用。
電動蝶閥工作原理:
工作(zuo)電源(yuan)通常有:AC220V,AC380V等(deng)(deng)。輸入(ru)信(xin)號:4~20mA 0~10v等(deng)(deng)弱電信(xin)號。由(you)調節型電動(dong)(dong)(dong)執行(xing)器和閥(fa)(fa)桿銜接調試好以后;以電能(neng)作(zuo)為驅動(dong)(dong)(dong)力(li)來驅動(dong)(dong)(dong)蝶閥(fa)(fa)閥(fa)(fa)板(ban),作(zuo)0~90°部(bu)分反轉(zhuan)回轉(zhuan)運動(dong)(dong)(dong)。接收工業(ye)自動(dong)(dong)(dong)化控制系統的4~20mA信(xin)號來精(jing)確(que)控制閥(fa)(fa)門開關(guan)度,從而達到流量、溫度、壓力(li)等(deng)(deng)不同需(xu)求參(can)數(shu)的調節和控制。
氣動蝶閥概述:
氣(qi)(qi)動(dong)(dong)蝶(die)(die)(die)閥(fa)(fa)是(shi)(shi)由氣(qi)(qi)動(dong)(dong)履行器和蝶(die)(die)(die)閥(fa)(fa)構(gou)成。氣(qi)(qi)動(dong)(dong)蝶(die)(die)(die)閥(fa)(fa)是(shi)(shi)用(yong)隨閥(fa)(fa)桿遷移(yi)轉(zhuan)變的圓形(xing)蝶(die)(die)(die)板做啟閉(bi)性,以完成啟用(yong)舉措的氣(qi)(qi)動(dong)(dong)閥(fa)(fa)門主要做截斷閥(fa)(fa)應(ying)用(yong),亦(yi)可(ke)計劃成具備(bei)調理或段閥(fa)(fa)兼調理的功(gong)效,今(jin)朝蝶(die)(die)(die)閥(fa)(fa)在高壓大中口徑管(guan)道上的應(ying)用(yong)越(yue)來越(yue)多(duo)。氣(qi)(qi)動(dong)(dong)蝶(die)(die)(die)閥(fa)(fa)分類(lei):不銹鋼氣(qi)(qi)動(dong)(dong)蝶(die)(die)(die)閥(fa)(fa),硬密封氣(qi)(qi)動(dong)(dong)蝶(die)(die)(die)閥(fa)(fa)軟密封氣(qi)(qi)動(dong)(dong)蝶(die)(die)(die)閥(fa)(fa),碳鋼氣(qi)(qi)動(dong)(dong)蝶(die)(die)(die)閥(fa)(fa)。
氣動蝶閥工作原理:
由氣(qi)動(dong)(dong)(dong)執行(xing)(xing)機構和蝶(die)閥連接組成(cheng),氣(qi)動(dong)(dong)(dong)蝶(die)閥是(shi)通(tong)過壓縮空(kong)氣(qi)進入(ru)氣(qi)動(dong)(dong)(dong)執行(xing)(xing)機構驅動(dong)(dong)(dong)執行(xing)(xing)器帶(dai)動(dong)(dong)(dong)圓型的蝶(die)板(ban)做90°旋轉運(yun)動(dong)(dong)(dong),來作(zuo)為(wei)管道開關和調(diao)節流量使用。氣(qi)動(dong)(dong)(dong)蝶(die)閥是(shi)通(tong)過0-90度(du)(du)(du)的啟(qi)閉作(zuo)為(wei)工作(zuo)原理。即為(wei)0度(du)(du)(du)為(wei)全(quan)關狀態,90度(du)(du)(du)為(wei)全(quan)啟(qi)狀態。在氣(qi)動(dong)(dong)(dong)執行(xing)(xing)器上(shang)添加(jia)定位器,輸(shu)入(ru)相應的信號,可對(dui)蝶(die)閥碟(die)版進行(xing)(xing)0-90度(du)(du)(du)的任意調(diao)節。

執行器對比:
執(zhi)(zhi)行(xing)(xing)器(qi)(qi)是自動(dong)(dong)(dong)化(hua)技術工(gong)具中接(jie)收控制信息并對受控對象施(shi)加(jia)控制作用的裝(zhuang)置。執(zhi)(zhi)行(xing)(xing)器(qi)(qi)按所(suo)用驅動(dong)(dong)(dong)能(neng)源(yuan)分為氣(qi)動(dong)(dong)(dong)、電動(dong)(dong)(dong)和液(ye)壓執(zhi)(zhi)行(xing)(xing)器(qi)(qi)三種,電動(dong)(dong)(dong)執(zhi)(zhi)行(xing)(xing)器(qi)(qi)與氣(qi)動(dong)(dong)(dong)執(zhi)(zhi)行(xing)(xing)器(qi)(qi)是為目(mu)前的主流執(zhi)(zhi)行(xing)(xing)器(qi)(qi)。我們貫良閥門就為大家分析電動(dong)(dong)(dong)執(zhi)(zhi)行(xing)(xing)器(qi)(qi)與氣(qi)動(dong)(dong)(dong)執(zhi)(zhi)行(xing)(xing)器(qi)(qi)之間的比較。
我們(men)主要從初始費用、操作(zuo)、性能、標度、動(dong)作(zuo)速度、抗腐蝕、操作(zuo)安(an)全性、維(wei)修(xiu)、故障安(an)全性售后保證,維(wei)護(hu),手動(dong)操作(zuo)這些方面來(lai)展開全面的比較。
從費用上來說,氣動執(zhi)行器價(jia)(jia)格相(xiang)對低廉,電(dian)動執(zhi)行器則相(xiang)對貴些(xie),這樣可以(yi)減(jian)少了氣動工程(cheng)的造(zao)價(jia)(jia)
操作上電動執(zhi)行器很難改變行程,而氣動則是采用模塊化,允許調節或數字控制。
性能上氣動(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(xiao)時最多(duo)啟動(dong)數量限制。氣動(dong)執行器(qi)工(gong)作(zuo)周(zhou)期(qi)長,保證2百萬(wan)次左右(you)動(dong)作(zuo)。氣動(dong)執行器(qi)可以精確可重復控制,0.25%精度。
標(biao)度上電動執行(xing)器較為復雜(za),電動執行(xing)器上力(li)矩(ju)開關,限制開關,在安裝上非常復雜(za),需要(yao)專業人士。
動(dong)作(zuo)速度上(shang)講氣(qi)動(dong)可以做出調整(zheng),電(dian)動(dong)執行(xing)器是固定的。閥門(men)的開關速度可獨立(li)設定。
抗腐蝕(shi):氣動執(zhi)(zhi)行(xing)器(qi)采用內部(bu)、外部(bu)環氧涂層,電動執(zhi)(zhi)行(xing)器(qi)采用外部(bu)標準噴(pen)漆,電動執(zhi)(zhi)行(xing)器(qi)進水會導致構件的損壞。
操(cao)作安全(quan)性,氣(qi)動執行器不需要電源,而電動執行器一般是采用220V或者(zhe)3相電380V電源。可以說(shuo)明電動執行器在潮濕工作的(de)環境中危險(xian)系(xi)數大些,氣(qi)動則(ze)不受影響(xiang)。
在維修(xiu)上(shang),氣動(dong)(dong)執行(xing)器簡(jian)單(dan),因(yin)為只有一(yi)個(ge)運動(dong)(dong)的部(bu)件(jian),而電動(dong)(dong)執行(xing)器的部(bu)件(jian)比較(jiao)多,要專(zhuan)業(ye)的人士(shi)才維修(xiu)。
售(shou)后保證(zheng)上(shang)任何執(zhi)(zhi)行器(qi)不正常工作,可以(yi)再(zai)無電源或氣源情況(kuang)下修理或更換。在維(wei)護上(shang),氣動執(zhi)(zhi)行器(qi)可以(yi)不需要油脂,
電動執(zhi)行器需(xu)要大量的油脂。手(shou)動操(cao)作上,失去(qu)了電源都可以實現手(shou)動操(cao)作。
目前電動執(zhi)行(xing)器時(shi)我們主(zhu)流的執(zhi)行(xing)器而氣(qi)動執(zhi)行(xing)器也(ye)不(bu)會被淘汰(tai)。都有著(zhu)自己的優勢與(yu)缺點。
