 工作原理

Working principle:

  雙驅動(dòng)平闆閥主要由執(zhi)行機構、閥體、插闆(pǎn)、密封裝置、行程開(kāi)關♍等部件組成。運(yun)行時輸出指令（電(diàn)源或氣源）給執行(háng)機構，由執行機構(gou)帶動插闆向外推(tuī)出，達到工況需要(yào)位置，撞動行程開(kāi)關停🤞止，由行程開(kāi)關反饋信号（開關(guān)信🔱号）給控制室。反(fǎn)之則😍關閉插闆閥(fá)（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.

使用說(shuo)明：

Operation instruction:

l  本閥可水平或(huo)垂直安裝，安裝時(shi)兩法蘭連接中間(jian)必👄須加密封墊片(pian)，然後均勻鎖緊螺(luo)栓。

l  手動操作時向(xiàng)外抽出為開，向内(nei)推進為關。不得在(zai)把手上增加輔助(zhu)器材。

l  執行機構應(ying)按其使用說明正(zhèng)确接線與操作。

l  若(ruò)長期存放應使設(she)備處于關閉狀态(tai)，各傳動部位應加(jiā)潤滑✏️油，不允許露(lu)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.
