 工作原理

Working principle:

  雙(shuang)驅動平闆閥(fa)主要由執行(háng)機構、閥體、插(chā)闆、密封裝置(zhi)💋、行程🔴開關等(děng)部件組成。運(yun)行時輸出指(zhǐ)令（電源或氣(qi)源⛱️）給執🈲行機(ji)構，由⁉️執行機(jī)構帶動插闆(pan)向外推出，達(da)到工💚況需要(yào)位置，撞動行(háng)程📱開關停止(zhi)，由行程開關(guān)反饋信💔号（開(kāi)關信号）給控(kòng)制室。反之則(zé)✍️關閉插闆閥(fa)（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(fa)可水平或垂(chuí)直安裝，安裝(zhuang)時兩法蘭連(lian)接中間😄必須(xū)加密封🌍墊片(pian)，然後均勻鎖(suo)緊螺栓。

l  手動(dòng)操作時向外(wai)抽出為開，向(xiang)内推進為關(guan)。不得在把手(shǒu)上增🤟加🌂輔助(zhù)器材。

l  執行機(jī)構應按其使(shi)用說明正确(que)接線與操作(zuò)。

l  若長期存放(fang)應使設備處(chu)于關閉狀态(tài)，各傳動部位(wèi)‼️應加潤滑油(you)，不允許露天(tiān)存放或堆置(zhi)。

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.
