電動(dòng)閘閥概述:
電動(dòng)閘閥閥簡(jiǎn)單地說(shuō)就是用電動(dòng)執(zhí)行器控制閘閥,從而實(shí)現(xiàn)閥門(mén)的開(kāi)和關(guān)。其可分為上下兩部分,上半部分為電動(dòng)執(zhí)行器,下半部分為閥門(mén)動(dòng)作力距比電動(dòng)閥門(mén)大,電動(dòng)閥門(mén)開(kāi)關(guān)動(dòng)作速度可以調(diào)整,結(jié)構(gòu)簡(jiǎn)單,易維護(hù),動(dòng)作過(guò)程中因氣體本身的緩沖特性,不易因卡住而損壞,但必須有氣源,且其控制系統(tǒng)也比電動(dòng)閥門(mén)復(fù)雜。 電動(dòng)閘閥響應(yīng)靈敏,安全可靠,很多對(duì)控制要求高的廠專(zhuān)為氣動(dòng)儀表控制元件設(shè)置壓縮空氣站。電動(dòng)的就是要電。并能控制其流量的裝置。進(jìn)口電動(dòng)閘閥動(dòng)作力距比電動(dòng)閥門(mén)大,電動(dòng)閥門(mén)開(kāi)關(guān)動(dòng)作速度可以調(diào)整,結(jié)構(gòu)簡(jiǎn)單,易維護(hù),動(dòng)作過(guò)程中因氣體本身的緩沖特性,不易因卡住而損壞,但必須有氣源,且其控制系統(tǒng)也比電動(dòng)閥門(mén)復(fù)雜。 電動(dòng)閘閥響應(yīng)靈敏,安全可靠,很多對(duì)控制要求高的廠專(zhuān)為氣動(dòng)儀表控制元件設(shè)置壓縮空氣站。進(jìn)口電動(dòng)閘閥并能控制其流量的裝置。其操作原理 電動(dòng)閥通常由電動(dòng)執(zhí)行機(jī)構(gòu)和閥門(mén)連接起來(lái),經(jīng)過(guò)安裝調(diào)試后成為電動(dòng)閥。電動(dòng)閥使用電能作為動(dòng)力來(lái)接通電動(dòng)執(zhí)行機(jī)構(gòu)驅(qū)動(dòng)閥門(mén),實(shí)現(xiàn)閥門(mén)的開(kāi)關(guān)、調(diào)節(jié)動(dòng)作。從而達(dá)到對(duì)管道介質(zhì)的開(kāi)關(guān)或是調(diào)節(jié)目的。
進(jìn)口電動(dòng)閘閥原理特征:其可分為上下兩部分,上半部分為電動(dòng)執(zhí)行器,下半部分為閥門(mén)。
Electric gate valve is simply the electric actuator control valve, in order to achieve the valve on and off. It can be divided into two parts, the upper part of electric actuators, valve actuation torque than the lower half into a large electric valve, electric valve switching speed can be adjusted, simple structure, easy maintenance, the course of action because of the gas itself cushioning properties, not easy to get stuck due to damage, but there must be gas source, and its control system is also more complex than an electric valve. Electric valve response sensitive, safe and reliable, many of the requirements for the control of plant height pneumatic control components designed for setting air station. Electric power is to. And control means which can flow. Imported electric valve operation torque than the electric valve large, electric valve switching speed can be adjusted, simple structure, easy maintenance, the course of action due to buffering characteristics of the gas itself is not easy to get stuck due to damage, but there must be gas source, and its control system is also more complex than an electric valve. Electric valve response sensitive, safe and reliable, many of the requirements for the control of plant height pneumatic control components designed for setting air station. Imported electric valve and control device of its traffic. Its principle of operation is usually connected by electric valve actuators and valves up, after becoming the electric valve installation. Electric valve using electricity as the power to turn electric actuator valve drive, to achieve the valve switch, adjust the action. Switch the pipeline so as to achieve the purpose of the media or adjust.
Imported electric valve principle characteristics: it can be divided into two parts, the upper part of the electric actuator, the valve into the lower half.
進(jìn)口電動(dòng)執(zhí)行器可分為三類(lèi),分別用于不同的閥門(mén)類(lèi)別:
1、角行程:0~90°角行程,用于控制球閥、旋塞閥、蝶閥和百葉閥之類(lèi)的角行程閥門(mén);
2、多回轉(zhuǎn)式:需要運(yùn)行超過(guò)360°才能實(shí)現(xiàn)閥門(mén)的啟閉,主要用于截止閥、管夾閥和隔膜閥;
3、直行程:輸出的是力,產(chǎn)生的是位移,主要用于閘閥和滑板閥。
進(jìn)口電動(dòng)閘閥安裝使用注意事項(xiàng):
1、電動(dòng)閘閥可安裝在水平管路或垂直管路上,單雙閘板閘閥應(yīng)安裝在水平管路上,且手輪應(yīng)位于閥門(mén)上方,不允許朝下安裝。
2、電動(dòng)閘閥通常采用法蘭連接,特殊場(chǎng)合也有用焊接連接、螺紋連接。
3、對(duì)于大口徑及高壓的閘閥,啟閉力矩較大。為了減小啟閉力矩,可采用安裝旁通閥的辦法。旁通閥安裝在主閘閥外部,它的進(jìn)出口與主閘閥的兩側(cè)練練連接,并聯(lián)聯(lián)通。主閘閥開(kāi)啟前應(yīng)先開(kāi)通旁通閥,進(jìn)入閥后,使主閘閥閘板前后的壓力差減小,從而減小主閘閥的開(kāi)啟力矩。旁通閥口徑的選用應(yīng)根據(jù)主閥口徑和使用要求考慮。
4、電動(dòng)閘閥的介質(zhì)溫度、壓力,對(duì)使用的可靠性應(yīng)引起注意。在高溫、高壓時(shí),由于溫度的變化可能使閘板鍥死,同時(shí)因各處介質(zhì)溫度不均勻,易產(chǎn)生不密封現(xiàn)象。鍥式但閘板閥尤為明顯。
