工作原理
Working principle:
雙驅動平闆閥主要由執行機構、閥體、插闆(pǎn)、密封裝(zhuāng)置、行程開(kāi)關等(děng)部件組(zǔ)成。運行時輸(shū)出指令（電源或氣源）給執行機構，由執行機構帶動插闆(pǎn)向外推出，達到工況需要(yào)位置，撞動行程開關停止，由行程開關反饋信(xìn)号（開關信号）給控制(zhì)室。反之則關閉插闆閥(fá)（向内推(tuī)進）。
The valve is mainly made up of actuator, body, disc, seal device and journey switch etc. Instruction is transmitted to the actuator. The actuator drives disc draw out to reach the requiring position and then bumps the journey switch to stop. Journey switch feeds back the signal to control room. Otherwise close disc.
使(shǐ)用說明：
Operation instruction:
l 本(běn)閥可水平或(huò)垂直安裝(zhuāng)，安裝時(shí)兩法(fǎ)蘭連接中間必須加密封墊片，然後均勻鎖緊螺栓(shuān)。
l 手動操作時向外抽出為開，向内推進為關(guān)。不得在(zài)把手上增加輔助器材。
l 執(zhí)行機構應按其使用(yòng)說明正确接線與操作。
l 若(ruò)長期(qī)存放應(yīng)使(shǐ)設備處于關閉狀态，各傳動部位應加潤滑油，不允許露(lù)天存放或堆置。
l The valve can be installed in horizontal or vertical. Add seal cushion between two flanges connection and screw down bolt.
l Draw out handle means open and push in means close. Assistant lever can’t be added to handle.
l Actuator must be connected and operated exactly according to the operation instruction.
l Add lubricant to transmission part when valve is long stored. It should not be placed or piled up in the open air.
