手動(dong)高性能密閉(bì)蝶閥；通過轉(zhuan)動手輪，經蝸(wo)輪副減速，帶(dài)動閥軸🙇🏻、蝶闆(pǎn)作90°範圍内的(de)旋轉，達到截(jie)斷、連通或調(diào)節流☀️量的目(mù)的。閥門的開(kāi)啟或關閉位(wei)置均由限位(wei)機構限位，并(bìng)有指示機構(gou)🐆顯示蝶闆位(wèi)置狀态。

自動(dong)高性能密閉(bì)蝶閥；由電動(dong)執行器接受(shou)變送、調節DCS、PLC等(děng)上位🌈儀♈表的(de)控制信号或(huo)操作器手控(kong)信号，輸出角(jiǎo)位移帶動傳(chuan)動軸，把動力(li)傳給閥軸帶(dài)動蝶闆作同(tóng)步旋轉運動(dong)，達到全開、全(quan)閉及任意調(diao)節的目的。電(dian)動執行器與(yǔ)蝶闆的開度(dù)同步反饋0～10mA或(huo) 4～20mA直流電🈲信号(hao)，用戶可☂️根據(jù)電流信🏃号來(lai)控制蝶闆的(de)任意開🈚度，達(da)到調節的目(mu)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(diao)試：

Installation and regulation

l  安裝前必(bì)須清潔閥體(ti)内腔，不允許(xǔ)有任何雜物(wù)和污垢附着(zhe)（特🐇别注意密(mi)封面、密封圈(quan)的清潔）。

l  安裝(zhuāng)前檢查閥門(mén)各部位是否(fǒu)有松動現象(xiang)，對閥門☀️進行(hang)開啟🐉、關🤩閉一(yi)個周期是否(fǒu)有異常現象(xiang)，同時檢查閥(fa)門的🚶‍♀️啟閉位(wei)置是否準确(que)。

l  水平安裝或(huo)垂直安裝的(de)閥門閥軸應(ying)處于水平位(wei)置，傳🌈動裝👉置(zhi)🐪不允許作起(qǐ)吊用，并嚴禁(jin)損傷。

l  本閥具(ju)有一定的雙(shuang)向密封性能(neng)，若隻需控制(zhì)單方向流動(dòng)的介質時，其(qi)安裝方向應(ying)參照閥體上(shang)箭頭所示，該(gai)箭頭所指為(wei)介質流向。

l  安(ān)裝如示意圖(tu)，加密封墊後(hou)均勻鎖緊聯(lián)接螺栓。

l  調整(zhěng)完成後必須(xu)進行綜合性(xing)能檢查：接通(tong)電源開啟閥(fa)🙇‍♀️門，當閥門至(zhì)“全開”“全閉”位(wei)置時，行程控(kòng)制機構應準(zhun)🛀确地🧑🏾‍🤝‍🧑🏼切斷電(dian)源，而轉矩限(xian)位機構處于(yu)臨界動作狀(zhuàng)态。開度指⭐示(shi)機構應準确(que)地顯示閥門(men)的開啟📞狀态(tai)。

l  電動切換手(shou)動操作時，應(ying)切斷電源，不(bu)得在手輪上(shang)再增加輔助(zhù)杠杆，手輪順(shùn)時針旋轉為(wéi)關，反之為開(kai)，閥闆開啟角(jiǎo)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°.
