工作原理：

Working principle

  采用雙偏心密封結(jié)構(gòu)，關(guān)閉時(shí)越關(guān)越緊，開(kāi)啟后確保密封面與密封圈脫離接觸，保護(hù)密封圈不受損傷，延長(zhǎng)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(jié)構(gòu)，蝶板為桁架式結(jié)構(gòu)，其強(qiáng)度高、過(guò)流面積大、流阻小、節(jié)省能源。本閥具有介質(zhì)雙向截止密封功能，其滲漏量為零。

  手動(dòng)高性能密閉蝶閥；通過(guò)轉(zhuǎn)動(dòng)手輪，經(jīng)蝸輪副減速，帶動(dòng)閥軸、蝶板作90°范圍內(nèi)的旋轉(zhuǎn)，達(dá)到截?cái)?、連通或調(diào)節(jié)流量的目的。閥門的開(kāi)啟或關(guān)閉位置均由限位機(jī)構(gòu)限位，并有指示機(jī)構(gòu)顯示蝶板位置狀態(tài)。

  自動(dòng)高性能密閉蝶閥；由電動(dòng)執(zhí)行器接受變送、調(diào)節(jié)DCS、PLC等上位儀表的控制信號(hào)或操作器手控信號(hào)，輸出角位移帶動(dòng)傳動(dòng)軸，把動(dòng)力傳給閥軸帶動(dòng)蝶板作同步旋轉(zhuǎn)運(yùn)動(dòng)，達(dá)到全開(kāi)、全閉及任意調(diào)節(jié)的目的。電動(dòng)執(zhí)行器與蝶板的開(kāi)度同步反饋0～10mA或 4～20mA直流電信號(hào)，用戶可根據(jù)電流信號(hào)來(lái)控制蝶板的任意開(kāi)度，達(dá)到調(diào)節(jié)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  安裝前必須清潔閥體內(nèi)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(dòng)現(xiàn)象，對(duì)閥門進(jìn)行開(kāi)啟、關(guān)閉一個(gè)周期是否有異?，F(xiàn)象，同時(shí)檢查閥門的啟閉位置是否準(zhǔn)確。

l  水平安裝或垂直安裝的閥門閥軸應(yīng)處于水平位置，傳動(dòng)裝置不允許作起吊用，并嚴(yán)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(dòng)的介質(zhì)時(shí)，其安裝方向應(yīng)參照閥體上箭頭所示，該箭頭所指為介質(zhì)流向。

l  安裝如示意圖，加密封墊后均勻鎖緊聯(lián)接螺栓。

l  調(diào)整完成后必須進(jìn)行綜合性能檢查：接通電源開(kāi)啟閥門，當(dāng)閥門至“全開(kāi)”“全閉”位置時(shí)，行程控制機(jī)構(gòu)應(yīng)準(zhǔn)確地切斷電源，而轉(zhuǎn)矩限位機(jī)構(gòu)處于臨界動(dòng)作狀態(tài)。開(kāi)度指示機(jī)構(gòu)應(yīng)準(zhǔn)確地顯示閥門的開(kāi)啟狀態(tài)。

l  電動(dòng)切換手動(dòng)操作時(shí)，應(yīng)切斷電源，不得在手輪上再增加輔助杠桿，手輪順時(shí)針旋轉(zhuǎn)為關(guān)，反之為開(kāi)，閥板開(kāi)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(yùn)輸及保管：

Transportation and protection

l  運(yùn)輸時(shí)應(yīng)避免撞擊蝶閥及傳動(dòng)裝置，閥門應(yīng)處于全閉位置，以防在運(yùn)輸中密封面和傳動(dòng)部件損壞。

l  當(dāng)閥門水平放置運(yùn)輸時(shí)，傳動(dòng)裝置及傳動(dòng)部位應(yīng)懸空，以防止傳動(dòng)軸受力過(guò)大而變形損壞。

l  該閥應(yīng)存放在干燥的室內(nèi)，不允許露天存放或堆置。長(zhǎng)期存放時(shí)應(yīng)使閥門處于關(guān)閉狀態(tài)，各傳動(dòng)部位加潤(rùn)滑油，傳動(dòng)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.
