自動(dòng)高性能密閉蝶(die)閥；由電動執行(hang)器接受變送、調(diào)節DCS、PLC等上位😍儀🍉表(biao)的控制信号或(huò)操作器手控信(xìn)号，輸出角位移(yi)帶動傳動㊙️軸，把(ba)動力傳給閥軸(zhóu)帶動蝶闆作同(tong)步旋轉運👨‍❤️‍👨動，達(da)到全開、全🏃閉及(ji)任意調節的目(mu)的。電動執行器(qì)與蝶闆的開度(du)同步反饋0～10mA或 4～20mA直(zhi)流電信号，用戶(hu)可根據電流信(xìn)号來控制蝶闆(pǎn)的任意開⁉️度，達(dá)到調節的目的(de)。

The valve adopts double eccentric sealed structure. The more it is close, the more it is tight. The sealing surface will separate from sealing ring, which prevent the sealing ring from damaging. The material of sealing surface and ring is stainless steel whose resistance of abrasion and high temperature ensure the reliability of sealing performance. It adopts half shaft structure and the butterfly disc is trussed structure, having the features of great strength, big flow area, little lost of flow resistance and saving energy. The valve has the function of stopping and sealing medium in double directions and without leakage.

Manual high performance sealed butterfly valve: rotate hand wheel to drive the valve axle and butterfly disc rotate in the range of 90°to cut off, connect or adjust the flow. The open or close position of the valve gate is limited by the limit device. The indicating device displays the position of butterfly disc.

Automatic high performance sealed butterfly valve: control signal or manual signal of DCS or PLC meter is accepted, adjusted and transmitted by electric actuator. Then the actuator outputs the angle moving to drive the transmission shaft. It drives the axle and disc rotating synchronously in order to adjust freely, full open and close. The open angle between actuator and disc’s sync feedback DC signal is 0～10mA or 4～20mA. User can control the random open angle of disc according as the current signal.

安裝及調試：

l  安裝前檢查閥(fá)門各部位是否(fǒu)有松動現象，對(dui)閥門⚽進行🈲開啟(qi)、關閉一個周期(qi)是否有異常現(xian)象，同時檢查閥(fa)🈲門的啟閉💃🏻位置(zhi)是否🥵準确。

l  水平(ping)安裝或垂直安(ān)裝的閥門閥軸(zhou)應處于水平位(wei)😘置，傳動‼️裝置不(bú)允許作起吊用(yong)，并嚴禁損傷。

l  本(ben)閥具有一定的(de)雙向密封性能(neng)，若隻需控制單(dān)方向流動的🏃🏻‍♂️介(jiè)質時，其安裝方(fang)向應參照閥體(tǐ)上箭頭🐕所示✉️，該(gāi)箭頭所指為介(jie)質流向。

l  安裝如(rú)示意圖，加密封(feng)墊後均勻鎖緊(jǐn)聯接螺栓。

l  調整(zhěng)完成後必須進(jìn)行綜合性能檢(jian)查：接通電源開(kāi)啟閥門，當閥♊門(men)至“全開”“全閉”位(wèi)置時，行程控制(zhì)機構應準确地(di)切斷電源，而轉(zhuan)🌐矩限位機構處(chù)于臨界動作狀(zhuàng)态。開度指💯示機(ji)構☀️應準确🧡地顯(xiǎn)示閥門的開啟(qǐ)狀态。

l  電動切換(huan)手動操作時，應(yīng)切斷電源，不得(de)在手輪上再增(zēng)加輔助✂️杠杆，手(shǒu)輪順時針旋轉(zhuǎn)為關，反之為開(kāi)🚶‍♀️，閥闆👈開啟🚩角度(dù)🌂為0°~90°。

l   The body must be cleaned before installed and there is no dirt and sundries clinging to the body, especially the sealing surface and ring.

l   Check the valve gate before install. Open and close the valve by hand for a period and check the open-close position of the valve gate.

l   The valve axle must be on the horizontal position when installed in horizontal or vertical. The transmission device cannot be hoisted and avoid damage when installed.

l   The valve has the feature of double-sealing performance. The installation direction should refer to the arrow on the valve body, which indicates the medium flow direction, when control the flow of medium in single direction.
