Working principle

  采用雙偏心密(mì)封結構，關閉時越(yue)關越緊，開啟後确(que)保密封面與密封(feng)圈完全脫離接觸(chu)，保護密封圈不受(shou)損傷，延長使用壽(shou)命。密封面、密封圈(quan)選用不鏽鋼制作(zuò)，其耐鏽蝕、耐高溫(wēn)性保證了密封性(xìng)能的可靠。采用半(ban)軸結構，蝶闆為桁(heng)架式結構，其強度(du)高、過流👨‍❤️‍👨面積大、流(liu)阻小、節省能源。本(běn)閥具有介質雙向(xiang)截止🧑🏽‍🤝‍🧑🏻密封功能，其(qi)滲漏量為零。

  手動(dòng)高性能密閉蝶閥(fa)；通過轉動手輪，經(jīng)蝸輪副減速，帶動(dòng)📐閥軸、蝶闆作90°範圍(wéi)内的旋轉，達到截(jie)斷、連通或調節流(liu)📐量的目的。閥門的(de)開啟或關閉位置(zhì)均由限位機構限(xiàn)位，并有指示機構(gòu)🧑🏽‍🤝‍🧑🏻顯示蝶闆位置狀(zhuàng)态。

  自動高性能密(mi)閉蝶閥；由電動執(zhi)行器接受變送、調(diao)節DCS、PLC等上位儀表的(de)控制信号或操作(zuò)器手控信号，輸出(chū)角🔞位移帶動傳動(dòng)📐軸，把動力傳給閥(fá)軸帶動蝶闆作同(tóng)步旋轉運動，達到(dao)全開、全閉及任意(yi)調節的目的。電動(dòng)執㊙️行器與蝶♌闆的(de)開度✏️同步反饋0～10mA或(huò) 4～20mA直流電信号，用戶(hù)可根據電流信号(hao)來控制蝶闆的任(ren)意開度，達到調節(jie)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.

安裝及調(diào)試：

Installation and regulation

l  安裝前必須清(qing)潔閥體内腔，不允(yǔn)許有任何雜物和(he)污垢附着（特别注(zhù)意密封面、密封圈(quān)的清潔）。

l  安裝前檢(jiǎn)查閥門各部位是(shi)否有松動現象，對(dui)閥門進行開啟、關(guan)閉一個周期是否(fǒu)有異常現象，同時(shí)檢查閥門的啟閉(bi)位置是否準确。

l  水(shuǐ)平安裝或垂直安(ān)裝的閥門閥軸應(yīng)處于水平位置，傳(chuan)♋動裝🧑🏾‍🤝‍🧑🏼置不允許作(zuo)起吊用，并嚴禁損(sǔn)傷。

l  本閥具有一定(dìng)的雙向密封性能(néng)，若隻需控制單方(fang)向流動🐕的介質時(shí)，其安裝方向應參(cān)照閥體上箭頭㊙️所(suǒ)示，該箭頭所指為(wei)介質流向。

l  安裝如(rú)示意圖，加密封墊(niàn)後均勻鎖緊聯接(jie)螺栓。

l  調整完成後(hou)必須進行綜合性(xing)能檢查：接通電源(yuan)開啟閥門❤️，當閥門(mén)至“全開”“全閉”位置(zhi)時，行程控制機構(gòu)應準📞确地切斷👉電(diàn)源，而轉矩限位機(ji)構處于臨界動作(zuo)狀态⚽。開度指示機(ji)構應準确地顯示(shì)閥門的開啟狀态(tài)。

l  電動切換手動操(cao)作時，應切斷電源(yuan)，不得在手輪上再(zai)增加♌輔助杠杆，手(shou)輪順時針旋轉為(wéi)關，反之為開🚶‍♀️，閥闆(pan)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°.

運輸(shu)及保管：

Transportation and protection

l  運輸時應(ying)避免撞擊蝶閥及(jí)傳動裝置，閥門應(ying)處于全閉位置，以(yi)㊙️防在運輸中密封(fēng)面和傳動部件損(sun)壞。

l  當閥門水平放(fang)置運輸時，傳動裝(zhuāng)置及傳動部位應(ying)懸空🔞，以防止傳動(dòng)軸受力過大而變(biàn)形損壞。

l  該閥應存(cun)放在幹燥的室内(nei)，不允許露天存放(fàng)或堆置。長期存放(fàng)時應使閥門處于(yú)關閉狀态，各傳動(dòng)部🛀位加潤滑油，傳(chuan)動裝置作🏃🏻防潮、防(fáng)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.

l   The valve should be stored in dry room. It should be in full close state when long stored. Add lubrication to the transmission part and the device should be dampproof and dustproof.
