Rotate the hａnd wheel by hａnd to drive worm gear and transmission shaft. The power will be transported to the two overhanging and connecting rod to rotate the butterfly disc quickly in horizontal in order to open or close the valve. The valve gate will be in full open state when butterfly disc move to the horizontal place with pipe axis. The valve gate will cut off medium and be in the sealed state when the butterfly disc moves to the vertical place with pipe axis. The switch position of butterfly disc is limited by the adjusting screw pole on the worm gear transmission device. The indicating device displays the position of the valve switch.

Start up the control switch, the first step transmission device will drive worm gear and transmission shaft. The power will be transported to the two overhanging and connecting rod to rotate the butterfly disc quickly in horizontal in order to open or close the valve. The valve gate will be in full open state when butterfly disc move to the horizontal place with pipe axis. The valve gate will cut off medium and be in the sealed state when the butterfly disc moves to the vertical place with pipe axis. The switch position of butterfly disc is limited by the adjusting screw pole on the worm gear transmission device. The stroke mechanism of first step transmission device will cut down the power. The torque control device of first step transmission device will drop and cut down the power at the same time when the torque is more than requirement of sealing.

安裝及調(diào)試：

Installation and regulation

• 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。

• 安裝前必須清潔閥門內(nèi)腔及密封面，不允許有任何雜物和污垢附著。

• 安裝前先試運(yùn)行閥門，啟閉一個(gè)周期，按客戶工作系統(tǒng)要求對(duì)閥門限位裝置作適當(dāng)?shù)恼{(diào)整（出廠時(shí)已作標(biāo)準(zhǔn)調(diào)整），運(yùn)行無誤后將閥門處于全閉狀態(tài)再進(jìn)行安裝。

• 安裝時(shí)請(qǐng)注意閥體上標(biāo)注（箭頭）的介質(zhì)流向，安裝如示意圖，加密封墊后均勻鎖緊聯(lián)接螺栓。

• 調(diào)整完成后必須進(jìn)行綜合性能檢查：接通電源開啟閥門，當(dāng)閥門至“全開”“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)。開度指示機(jī)構(gòu)應(yīng)準(zhǔn)確地顯示閥門的開啟狀態(tài)。

• 若傳動(dòng)裝置配備手動(dòng)，手動(dòng)與電動(dòng)機(jī)構(gòu)轉(zhuǎn)換時(shí)，應(yīng)切斷電源。

• The valve axle must be on the horizontal position when installed. The transmission device cannot be hoisted and avoid damage when installed.

• The body must be cleaned before installed and there is no dirt and sundries clinging to the body.

• Trial operation of valve should be done before install. Open and close the valve by hａnd for a period. Adjust the limit device of the valve gate according to the working system condition of user. Install the valve in full close state when there is no mistake.

• Pay attention to the flow direction of medium showed on the body. Installation of flange connecting valve is on diagram. Lock down the connecting bolt after add sealing washer.

• 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.

• Cut down the power when the manual and electric device is switched.

• The valve is single-direction valve. Open the side valve to discharge pressure and then open the valve in manual or electric when the diameter is below 1000mm and pressure is more than 1bar.

• Avoid bumping of the valve and transmission device. The valve is in full close in order to avoid damage of disc and driving part.

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

• The valve should be stored in dry room and should not be piled up in open air.

• It should be in full close state when long stored. Add lubrication to the transmission part and the device should be dampproof and dustproof.
