 工作原理

Working principle:

  雙驅動平板閥主要由執行機構、閥體、插板、密封裝置、行程開關等部件組成。運行時輸出指令（電源或氣源）給執行機構，由執行機構帶動插板向外推出，達到工況需要位置，撞動行程開關停止，由行程開關反饋信號（開關信號）給控制室。反之則關閉插板閥（向內推進）。

  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.

使用說明：

Operation instruction:

l  本閥可水平或垂直安裝，安裝時兩法蘭連接中間必須加密封墊片，然后均勻鎖緊螺栓。

l  手動操作時向外抽出為開，向內推進為關。不得在把手上增加輔助器材。

l  執行機構應按其使用說明正確接線與操作。

l  若長期存放應使設備處于關閉狀態，各傳動部位應加潤滑油，不允許露天存放或堆置。

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.
