 工作(zuo)原理

Working principle:

  雙驅(qū)動平闆閥(fa)主要由執(zhi)行機構、閥(fá)體、插闆、密(mi)封裝置、行(hang)程開關等(děng)部件組成(cheng)。運行時輸(shū)出指令（電(dian)源或🧑🏽‍🤝‍🧑🏻氣源(yuán)）給執行機(ji)構，由執行(hang)📐機構帶動(dong)插闆向外(wai)推出，達到(dao)工況需要(yao)位置，撞動(dòng)行程開關(guān)停止，由行(háng)程開關反(fǎn)饋信号（開(kai)關信号）給(gei)控制室。反(fǎn)之則🤟關閉(bi)插闆閥（向(xiàng)内推進）。

  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(shi)用說明：

Operation instruction:

l  本(ben)閥可水平(píng)或垂直安(an)裝，安裝時(shi)兩法蘭連(lian)接中間必(bi)須加密封(feng)墊片，然後(hòu)均勻鎖緊(jǐn)螺栓。

l  手動(dong)操作時向(xiang)外抽出為(wéi)開，向内推(tuī)進為關。不(bu)得在把🔅手(shou)上🥵增加輔(fu)助器材。

l  執(zhí)行機構應(ying)按其使用(yong)說明正确(que)接線與操(cāo)作。

l  若長期(qi)存放應使(shǐ)設備處于(yu)關閉狀态(tài)，各傳動部(bu)位應🐕加潤(run)滑油，不允(yǔn)許露天存(cun)放或堆置(zhì)。

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.
