 工作(zuo)原理

Working principle:

  雙驅動平(ping)闆閥主要由執(zhí)行機構、閥體、插(chā)闆、密封裝置、行(hang)程開關等部件(jiàn)組成。運行時輸(shu)出指令（電源或(huo)氣源）給執行機(jī)構，由執行機構(gou)帶動插闆向外(wài)推出，達到工況(kuang)需要✉️位置，撞動(dong)行程開關停止(zhǐ)，由行程開關反(fǎn)饋信🏃🏻号（開關信(xìn)号）給控制室。反(fǎn)之則關閉插闆(pǎn)閥（向内推進）。

  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  本閥可(kě)水平或垂直安(an)裝，安裝時兩法(fa)蘭連接中間必(bì)須加💁密♈封墊片(pian)，然後均勻鎖緊(jǐn)螺栓。

l  手動操作(zuo)時向外抽出為(wéi)開，向内推進為(wéi)關。不得在把⭕手(shou)✍️上❌增🧑🏽‍🤝‍🧑🏻加輔助器(qi)材。

l  執行機構應(ying)按其使用說明(míng)正确接線與操(cao)作。

l  若長期存放(fang)應使設備處于(yú)關閉狀态，各傳(chuan)動部位應加潤(rùn)滑油，不允許露(lù)天存放或堆置(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.
