working principle:

  雙驅動平闆閥(fá)主要由執行機(jī)構、閥體、插(chā)闆、密(mì)封裝置、行(háng)程開關等部件組成(chéng)。運行時輸出指令（電(diàn)源或氣源(yuán)）給執行(háng)機構，由(yóu)執行機構帶動插闆向外(wài)推出(chū)，達到工(gōng)況需(xū)要(yào)位置，撞(zhuàng)動行程(chéng)開關(guān)停止(zhǐ)，由行(háng)程開關(guān)反饋信号（開(kāi)關信号）給(gěi)控制室。反之(zhī)則關閉(bì)插闆閥（向(xiàng)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.

使用說明：

operation instruction:

l  本(běn)閥可水平(píng)或垂直安(ān)裝，安(ān)裝時兩法蘭連(lián)接中間必(bì)須加(jiā)密封(fēng)墊片(piàn)，然後(hòu)均勻(yún)鎖緊螺栓。

l  手動操作時向(xiàng)外抽(chōu)出為開，向(xiàng)内推(tuī)進(jìn)為(wéi)關。不(bú)得在把(bǎ)手上增(zēng)加輔(fǔ)助器材。

l  執(zhí)行機構(gòu)應(yīng)按其(qí)使用說明(míng)正确接線與操(cāo)作。

l  若(ruò)長期存放應使設備(bèi)處(chù)于關閉(bì)狀态，各傳動部(bù)位應(yīng)加潤(rùn)滑油，不允許(xǔ)露天存(cún)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.
