The relative electric execute. Working principle and main is refer to the operation manual of electric executor. 2、電動(dòng)蝶閥按作業(yè)方式可分為電開式和電關(guān)式兩種。電開式:無信號(hào)電流時(shí),閥處于關(guān)閉位置,隨著信號(hào)電流從0~10A或從4~20mA的增加,閥從關(guān)閉位置逐漸轉(zhuǎn)向全開位置。電關(guān)式:無信號(hào)電流時(shí),閥處于開位置,隨著信號(hào)電流從0~10A或從4~20mA的增加,閥從全開位置逐漸轉(zhuǎn)向關(guān)閉位置。在一般情況下,用戶不提出要求,按電關(guān)式調(diào)整出廠。 2、The electric butterfly valve have open and close type according to the way. Electric and open type: When there is signal current, the valve is in close position. With the addition of signal current from 0~10A or 4~20A, the valve is from close position to open position. Electric and close type: When there is no signal current, the valve is in open position. With the addition of signal current from 0~10A or 4~20A, the valve is from open position to close position. Generally the valve leave the factory in electric and close type. 作用原理:從操作器來的信號(hào)電流,進(jìn)入電動(dòng)執(zhí)行機(jī)構(gòu),使其輸出一個(gè)相應(yīng)的角位移,帶動(dòng)連桿,使閥板有一個(gè)相應(yīng)的角位移。由于閥板在閥體內(nèi)轉(zhuǎn)動(dòng),改變流通截面,達(dá)到對(duì)介質(zhì)流量的調(diào)節(jié)。電動(dòng)蝶閥在設(shè)計(jì)上采用閥板在關(guān)閉狀態(tài)時(shí)有一始角10°,因此,在關(guān)閉時(shí),其泄漏面積較小,故其具有較低的泄漏量。當(dāng)信號(hào)電流因故中斷時(shí),可將電動(dòng)執(zhí)行機(jī)構(gòu)的電動(dòng)機(jī)“旋鈕”撥在手動(dòng)位置,然后將手輪連軸向外拉出,用手轉(zhuǎn)動(dòng)手輪。由手動(dòng)轉(zhuǎn)入自動(dòng)運(yùn)行時(shí),必須將“旋鈕”撥到“自動(dòng)”位置,并將手輪推入。 Working principle: The signal current from the operator enter in to electric execute structure. Make it output a suitable rotated angle movement. With the pole, the valve plate have a suitable rotated angle movement. Because the valve plate is rotated in valve body, change the flow section. Adjust the medium flow volume. When the electric butterfly valve is used valve plate, there is a start angle (10 degree)in design. So the leakage area is smaller, the leakage volume is lower. When signal current is broken, put the button of electric execute structure in hand position. Then the hand wheel is drawn out. Drive the hand wheel in hand. When the hand position change into automatic position, put the button on automatic position. 三、煙氣管道防爆電動(dòng)蝶閥安裝使用與維護(hù) Ⅲ、Installation and maintenance 1、電動(dòng)蝶閥最好安裝在水平管道上,如需安裝要垂直管道上,用戶在訂貨時(shí)應(yīng)注明。 The electric butterfly valve had better install the horizontal pipe. If the client request to install the vertical pipe. 2、煙氣管道防爆電動(dòng)蝶閥使用在振動(dòng)的情況下,安將時(shí)應(yīng)加支承和加固。 When the big mouth butterfly valve is used in vibrated condition, it should be support and strength. 3、電動(dòng)執(zhí)行機(jī)構(gòu)的調(diào)整、使用與維護(hù)見電動(dòng)執(zhí)行器說明書。 The adjustment of electric executor structure, operation and maintenance see the operation manual of elector. 四、主要外型及連接尺寸 Ⅳ.The main outline and connection size
