手動高(gao)性能密閉蝶(die)閥；通過轉動(dòng)手輪，經蝸輪(lun)副減速，帶🍉動(dong)🍓閥軸🐉、蝶闆作(zuò)90°範圍内的旋(xuan)轉，達到截斷(duan)、連通或調節(jie)流量的目的(de)。閥門的開啟(qi)或關閉位置(zhì)均由😄限位機(ji)構限位，并有(yǒu)指示機構顯(xiǎn)示蝶闆位置(zhì)狀态。

自動高(gāo)性能密閉蝶(die)閥；由電動執(zhí)行器接受變(bian)送、調節⭐DCS、PLC等🌈上(shang)位儀表的控(kòng)制信号或操(cāo)作器手控信(xìn)号，輸㊙️出角位(wei)移帶動㊙️傳動(dòng)軸，把動力傳(chuán)給閥軸帶動(dong)蝶闆作同步(bu)🌈旋轉運💯動，達(da)到✊全開、全閉(bì)及任意調節(jiē)的目的。電動(dòng)執行器與蝶(dié)✂️闆的開度同(tóng)步反饋0～10mA或 4～20mA直(zhi)流電信号，用(yòng)戶可根據電(diàn)流信号來控(kòng)制蝶❤️闆的任(rèn)意開度，達到(dao)調節的目的(de)。

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(shì)：

Installation and regulation

l  安裝前必須(xū)清潔閥體内(nei)腔，不允許有(yǒu)任何雜物和(hé)污垢😄附着（特(te)🏃🏻‍♂️别注意密封(feng)面、密封圈的(de)清潔）。

l  安裝前(qian)檢查閥門各(gè)部位是否有(you)松動現象，對(duì)閥門進行開(kāi)啟、關閉一個(ge)周期是否有(yǒu)異常現象，同(tong)時檢查閥✏️門(mén)的啟閉🔅位置(zhi)♉是否準确。

l  水(shui)平安裝或垂(chui)直安裝的閥(fá)門閥軸應處(chù)于水平位置(zhì)，傳動裝置不(bu)允許作起吊(diao)用，并嚴禁損(sun)傷。

l  本閥具有(you)一定的雙向(xiàng)密封性能，若(ruo)隻需控制單(dān)方向流動的(de)🧑🏽‍🤝‍🧑🏻介質時，其安(ān)裝方向應參(can)照閥體上箭(jian)頭所示，該箭(jian)頭所指為介(jie)質流向。

l  安裝(zhuang)如示意圖，加(jia)密封墊後均(jun)勻鎖緊聯接(jie)螺栓。

l  調整完(wan)成後必須進(jin)行綜合性能(neng)檢查：接通電(dian)源開✉️啟閥門(mén)，當閥🐇門至“全(quan)開”“全閉”位置(zhi)時，行程控制(zhi)機構應準确(què)地㊙️切斷電源(yuán)，而轉矩限位(wèi)機構處于臨(lin)界動作狀态(tai)。開度指示機(jī)構應準确地(di)顯示💯閥門的(de)開啟狀态。

l  電(dian)動切換手動(dong)操作時，應切(qiē)斷電源，不得(de)在手輪上再(zai)增加輔助杠(gàng)杆，手輪順時(shi)針旋轉為關(guan)，反之為開，閥(fa)闆開啟角度(dù)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(bao)管：

Transportation and protection

l  運輸時應(yīng)避免撞擊蝶(dié)閥及傳動裝(zhuang)置，閥門應處(chù)于全閉位置(zhi)，以防在運輸(shu)中密封面和(he)傳動部件損(sǔn)壞。

l  當閥門水(shui)平放置運輸(shū)時，傳動裝置(zhi)及傳動部位(wèi)應懸空，以防(fang)止傳動軸受(shòu)力過大而變(biàn)形損壞。

l  該閥(fá)應存放在幹(gàn)燥的室内，不(bu)允許露天存(cun)放或堆置😍。長(zhǎng)💘期🌈存放時應(yīng)使閥門處于(yú)關閉狀态，各(gè)傳動部♌位加(jiā)☂️潤滑油，傳動(dòng)裝⛷️置作防潮(chao)、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.
