進(jìn)口電動(dòng)防爆蝶閥產(chǎn)品簡(jiǎn)介：

德國(guó)洛克《DE LOCKE》進(jìn)口電動(dòng)防爆蝶閥由法蘭蝶閥（對(duì)夾式蝶閥）裝配上防爆電動(dòng)執(zhí)行器組合而成，是一種專門應(yīng)用于易燃易爆氣體、液體或粉塵等介質(zhì)的防爆閥門，設(shè)備均經(jīng)過(guò)防靜電處理，防護(hù)等級(jí)一般在IP65.67.68, 防爆等級(jí)為Exd ⅡBT4 或CT4的防爆標(biāo)志。根據(jù)介質(zhì)溫度高低的不同，選用不同的密形式，分為金屬密封和軟密封結(jié)構(gòu)，也可根據(jù)工況的需要選擇開(kāi)關(guān)型或調(diào)節(jié)型防爆電動(dòng)蝶閥（輸入4～20mA電流信號(hào)控制來(lái)調(diào)節(jié)流量的大?。诂F(xiàn)代工業(yè)自動(dòng)化控制領(lǐng)域中起到不可缺少的作用。

Introduction of imported electric explosion proof butterfly valve products:
The imported electric explosion-proof butterfly valve of German Rockwell "de Locke" is composed of flange butterfly valve (wafer butterfly valve) equipped with explosion-proof electric actuator. It is a kind of explosion-proof valve specially used for flammable and explosive gas, liquid or dust medium. The equipment has been treated with anti-static treatment. The protection grade is generally ip65.67.68, and the explosion-proof grade is Exd Ⅱ BT4 or cT4. According to the different temperature of medium, different sealing forms are selected, which are divided into metal sealing and soft sealing structures. Switch type or adjustable explosion-proof electric butterfly valve (input 4 ~ 20mA current signal control to adjust the flow) can also be selected according to the needs of working conditions, which plays an indispensable role in the field of modern industrial automation control.
