 工(gōng)作原理

Working principle:

  雙(shuang)驅動平闆(pan)閥主要由(yóu)執行機構(gòu)、閥體、插闆(pan)、密封裝置(zhì)㊙️、行✔️程開關(guān)等部件組(zu)成。運行時(shí)輸出指令(ling)（電源或氣(qì)源💞）給執🈲行(hang)機構，由💘執(zhi)行😍機構帶(dai)動插闆向(xiàng)外推出，達(dá)到工況需(xu)要位置，撞(zhuàng)動行程開(kāi)關停止，由(yóu)行程開關(guan)反饋信⭐号(hao)（開關信🌈号(hao)）給控制室(shi)。反之則關(guan)閉插闆👣閥(fá)（向内推進(jin)）。

  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(shui)平或垂直(zhi)安裝，安裝(zhuāng)時兩法蘭(lán)連接中間(jiān)必須加密(mi)封墊片，然(rán)後均勻鎖(suǒ)緊螺栓。

l  手(shou)動操作時(shí)向外抽出(chu)為開，向内(nèi)推進為關(guan)。不得在把(ba)手上增加(jia)輔助器材(cái)。

l  執行機構(gòu)應按其使(shi)用說明正(zhèng)确接線與(yu)操作。

l  若長(zhǎng)期存放應(yīng)使設備處(chù)于關閉狀(zhuàng)态，各傳動(dòng)部位應加(jiā)潤滑油，不(bú)允許露天(tian)存放或堆(dui)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.
