工作(zuo)原理：

Working principle

  采用雙偏心(xīn)密封結構，關閉時(shi)越關越緊，開啟後(hou)确保密封♍面與🐉密(mi)封圈完全脫離接(jiē)觸，保護密封圈不(bu)👄受損傷，延長使用(yong)壽😄命。密封面、密封(feng)圈選用不鏽鋼制(zhì)作，其💔耐鏽蝕、耐高(gao)溫性保證了密封(fēng)性能的可靠。采用(yòng)半軸結構，蝶闆為(wei)桁架式結構，其強(qiang)度高、過流面積大(da)、流阻👣小、節省能源(yuan)⛹🏻‍♀️。本閥具有介質雙(shuang)向截止💘密封功能(neng)，其滲漏量為零。

  手(shǒu)動高性能密閉蝶(dié)閥；通過轉動手輪(lun)，經蝸輪副減速💜，帶(dài)♉動閥軸、蝶闆作90°範(fan)圍内的旋轉，達到(dào)截斷、連通❌或調節(jie)流量的目的。閥門(men)的開啟或關閉位(wèi)置均由限位機構(gòu)限位㊙️，并有指✊示機(jī)構顯示蝶闆位置(zhì)狀态。

  自動高性能(néng)密閉蝶閥；由電動(dòng)執行器接受變送(sòng)、調📞節DCS、PLC等上位儀表(biǎo)的控制信号或操(cao)作器手控信号，輸(shū)♋出角位移帶動傳(chuan)動軸，把動力傳給(gěi)閥軸帶動蝶闆作(zuò)同步旋轉運😍動，達(da)到全開、全閉及任(rèn)意調節的目🌐的。電(diàn)動執行器與蝶闆(pǎn)的開度同步反饋(kuì)🐅0～10mA或 4～20mA直流電信号，用(yong)戶可🔅根據電流信(xin)号來控制蝶闆的(de)任意開度，達到調(diao)節的目的。

  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(jí)調試：

Installation and regulation

l  安裝前必須(xū)清潔閥體内腔，不(bu)允許有任何雜物(wu)和污垢附着💞（特别(bie)注意密封面、密封(fēng)圈的清潔）。

l  安裝前(qián)檢查閥門各部位(wèi)是否有松動現象(xiang)，對閥門進✍️行㊙️開啟(qi)、關閉一個周期是(shì)否有異常現象，同(tóng)時檢查閥門的啟(qǐ)閉💚位置是否準确(què)。

l  水平安裝或垂直(zhí)安裝的閥門閥軸(zhou)應處于水平位置(zhi)，傳動裝置不允許(xu)作起吊用，并嚴禁(jìn)損傷。

l  本閥具有一(yī)定的雙向密封性(xing)能，若隻需控制單(dan)方向流動🌈的介質(zhì)時，其安裝方向應(ying)參照閥體上箭頭(tou)所示，該箭頭所指(zhǐ)為介質流向。

l  安裝(zhuang)如示意圖，加密封(feng)墊後均勻鎖緊聯(lian)接螺栓。

l  調整完成(cheng)後必須進行綜合(hé)性能檢查：接通電(dian)源開⚽啟閥⛹🏻‍♀️門🏃🏻，當閥(fa)門至“全開”“全閉”位(wei)置時，行程控制機(ji)構應準🌐确地💁切斷(duàn)電源，而轉矩限位(wei)機構處于臨界動(dong)作狀态🐆。開度指示(shì)機構應準确地顯(xiǎn)示閥門的開啟狀(zhuang)态。

l  電動切換手動(dong)操作時，應切斷電(dian)源，不得在手輪上(shang)再增☂️加輔助杠杆(gan)，手輪順時針旋轉(zhuan)為關，反之為開，閥(fa)闆開啟角度為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. 

l   Installation of flange connecting valve is on diagram. Lock down the connecting bolt after add sealing washer.

l   Synthetic performance of the valve must be done after adjust is over: turn on the power and open the valve, the stroke control device should cut down the power exactly when the valve is in the state of full open or full close. While the torque limit device is in critical state. The open angle indicating device should display the open state of the valve gate exactly.

l   The power must be shut down when operating by manual. Assistant pole can’t be added to hand wheel. Clockwise rotation of hand wheel means open and anticlockwise means close. Open angle is 0~90°.

運(yun)輸及保管：

Transportation and protection

l  運輸時(shi)應避免撞擊蝶閥(fa)及傳動裝置，閥門(mén)應處于全閉位置(zhi)，以防在運輸中密(mi)封面和傳動部件(jian)損壞。

l  當閥門水平(píng)放置運輸時，傳動(dòng)裝置及傳動部位(wèi)應懸空，以防止傳(chuan)動軸受力過大而(ér)變形損壞。

l  該閥應(yīng)存放在幹燥的室(shì)内，不允許露天存(cún)放或堆置。長期存(cun)放時應使閥門處(chù)于關閉狀态，各傳(chuan)動部位加🌈潤滑油(you)，傳動裝♈置作防潮(cháo)、防塵處理。

l   Avoid bumping of valve and transmission device. The valve is in full close in order to avoid damage of sealing surface and driving part.

l   Transmission device and part should be hung up when the valve is in horizontal in order to prevent damage of driving axle.
