 工作原(yuan)理

Working principle:

  雙驅動平(ping)闆閥主要由(you)執行機構、閥(fá)體、插闆、密封(feng)裝☁️置、行🔞程開(kai)關等部件組(zu)成。運行時輸(shu)出指令（電源(yuan)或氣源）給執(zhi)行機構，由執(zhi)行⭐機構帶動(dòng)插闆向外推(tui)出，達到工況(kuàng)需要位置，撞(zhuàng)動行程開關(guan)停止，由行程(cheng)開關反饋信(xin)🈲号（開關信号(hào)）給控制室。反(fǎn)之則關閉插(chā)闆閥（向内推(tuī)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(ming)：

Operation instruction:

l  本閥可水平(píng)或垂直安裝(zhuang)，安裝時兩法(fa)蘭連接中間(jian)必須✂️加密封(fēng)墊片，然後均(jun)勻鎖緊螺栓(shuan)。

l  手動操作時(shi)向外抽出為(wéi)開，向内推進(jìn)為關。不得在(zài)把手上增加(jia)🥵輔助器材。

l  執(zhi)行機構應按(àn)其使用說明(míng)正确接線與(yǔ)操作。

l  若長期(qi)存放應使設(she)備處于關閉(bi)狀态，各傳動(dòng)部位應加潤(run)滑油，不允許(xu)露天存放或(huò)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.
