style="text-indent:25px">電動閥門連接形式，電動閥門與管道的連接形式主要有法蘭連接、悍接連接、對夾連接、螺紋連接、卡箍連接、卡套連接等方式。法蘭連接，定義：法蘭連接：法蘭連接是指由法蘭、墊片及螺栓三者相互連接作為一組組合密封結(jié)構(gòu)的可拆連接。管道法蘭系指管道裝置中配管用的法蘭，用在設備上系指設備的進出口法蘭。法蘭連接使用方便，能夠承受較大的壓力。法蘭連接適用范圍：法蘭連接可適用于各種公稱尺寸、公稱壓力的電動閥門，但對使用溫度有一定的限制，在高溫工況時，由于法蘭的連接螺栓易產(chǎn)生蠕變現(xiàn)象而造成泄漏，一般情況下法蘭連接推薦在s350^C溫度使用。</p><p

style="text-indent:25px">電動閥門與氣動閥門區(qū)別在哪里？氣動閥動作力距比電動閥門大，氣動閥門開關動作速度可以調(diào)整，結(jié)構(gòu)簡單，易維護，動作過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)也比電動閥門復雜。氣動閥門響應靈敏，安全可靠，很多對控制要求高的廠專為氣動儀表控制元件設置壓縮空氣站。氣動閥門執(zhí)行機構(gòu)動力源為氣源，氣源來源于空壓機，采用定位器將電控信號轉(zhuǎn)換成氣動控制信號，驅(qū)動氣動執(zhí)行機構(gòu)進行閥位調(diào)節(jié)。電動閥門執(zhí)行機構(gòu)動力源為電源，如果線路板或電機出現(xiàn)故障容易出現(xiàn)火花，所以一般應用在環(huán)境要求不高和沒有危險的場合就氣動執(zhí)行機構(gòu)和電動執(zhí)行機構(gòu)調(diào)節(jié)性能比較，氣動執(zhí)行機構(gòu)響應速度更快，能更適合應用在調(diào)節(jié)工況，所以生產(chǎn)調(diào)節(jié)閥的廠家都同時生產(chǎn)氣動執(zhí)行機構(gòu)與之配套。當電動閥門全開后，應將手輪倒轉(zhuǎn)少許，使螺紋之間嚴緊，以免松動損傷。智能一體化電動蝶閥供貨商</p><p
