工作原理：

Working principle

采用雙偏心密封結構，關閉時越關越緊，開啟后確保密封面與密封圈完全脫離接觸，保護密封圈不受損傷，延長使用壽命。密封面、密封圈選用不銹鋼制作，其耐銹蝕、耐高溫性保證了密封性能的可靠。采用半軸結構，蝶板為桁架式結構，其強度高、過流面積大、流阻小、節省能源。本閥具有介質雙向截止密封功能，其滲漏量為零。

手動高性能密閉蝶閥；通過轉動手輪，經蝸輪副減速，帶動閥軸、蝶板作90°范圍內的旋轉，達到截斷、連通或調節流量的目的。閥門的開啟或關閉位置均由限位機構限位，并有指示機構顯示蝶板位置狀態。

自動高性能密閉蝶閥；由電動執行器接受變送、調節DCS、PLC等上位儀表的控制信號或操作器手控信號，輸出角位移帶動傳動軸，把動力傳給閥軸帶動蝶板作同步旋轉運動，達到全開、全閉及任意調節的目的。電動執行器與蝶板的開度同步反饋0～10mA或 4～20mA直流電信號，用戶可根據電流信號來控制蝶板的任意開度，達到調節的目的。

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.

 

安裝及調試：

Installation and regulation

l  安裝前必須清潔閥體內腔，不允許有任何雜物和污垢附著（特別注意密封面、密封圈的清潔）。

l  安裝前檢查閥門各部位是否有松動現象，對閥門進行開啟、關閉一個周期是否有異常現象，同時檢查閥門的啟閉位置是否準確。

l  水平安裝或垂直安裝的閥門閥軸應處于水平位置，傳動裝置不允許作起吊用，并嚴禁損傷。

l  本閥具有一定的雙向密封性能，若只需控制單方向流動的介質時，其安裝方向應參照閥體上箭頭所示，該箭頭所指為介質流向。

l  安裝如示意圖，加密封墊后均勻鎖緊聯接螺栓。

l  調整完成后必須進行綜合性能檢查：接通電源開啟閥門，當閥門至“全開”“全閉”位置時，行程控制機構應準確地切斷電源，而轉矩限位機構處于臨界動作狀態。開度指示機構應準確地顯示閥門的開啟狀態。

l  電動切換手動操作時，應切斷電源，不得在手輪上再增加輔助杠桿，手輪順時針旋轉為關，反之為開，閥板開啟角度為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°.

 

運輸及保管：

Transportation and protection

l  運輸時應避免撞擊蝶閥及傳動裝置，閥門應處于全閉位置，以防在運輸中密封面和傳動部件損壞。

l  當閥門水平放置運輸時，傳動裝置及傳動部位應懸空，以防止傳動軸受力過大而變形損壞。

l  該閥應存放在干燥的室內，不允許露天存放或堆置。長期存放時應使閥門處于關閉狀態，各傳動部位加潤滑油，傳動裝置作防潮、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.

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.

 

維護及檢修：

Maintenance and examination

l  定期檢查傳動裝置的運行情況：電機部分、控制開關是否異常。

l  定期給閥的傳動部位加潤滑油。

l  定期檢查閥的密封填料處，補充、更換填料以防介質外泄。

l  對閥門周期性維護時應全面檢查閥的各密封部位、傳動部位，對各密封部位應進行檢測，對檢測數據應記錄在案。

l   Check the working condition of electric parts, control switch and sealing of pneumatic device regularly.

l   Add lubricant to the transmission parts regularly.

l   Check the sealing filler of the valve regularly. Complement or change filler avoiding leakage of medium.

l   Check the sealing parts and transmission parts thoroughly. Detect the sealing parts and the detecting data should be registered.
