手輪在頂部）。3、帶有旁通閥的閘閥在開啟前應(yīng)先打開旁通閥（以平衡進(jìn)出口的壓差及減小開啟力）。4、帶傳動機(jī)構(gòu)的閘閥，按產(chǎn)品使用說明書的規(guī)定安裝。5、如果閥門經(jīng)常開關(guān)使用, 每月至少潤滑一次。刀型閘閥的啟閉件是閘板，閘板的運動方向與流體方向相垂直，刀型閘閥只能作全開和全關(guān)，不能作調(diào)節(jié)和節(jié)流。閘板有兩個密封面，通常為 50，楔式刀型閘閥的閘板可以做成一個整體，叫做剛性閘板；也可以做成能產(chǎn)生微量變形的閘板，以改善其工藝性，彌補密封面角度在加工過程中產(chǎn)生的偏差，這種閘板叫做彈性閘板。刀型閘閥關(guān)閉時，密封面可以只依靠介質(zhì)壓力來密封。大部分刀型閘閥是采用強(qiáng)制密封的，即閥門關(guān)閉時，要依靠外力強(qiáng)行將閘板壓向閥座，以保證密封面的密封性。</p><p

3)用戶在安裝前必須考慮預(yù)留閥門驅(qū)動裝置的必要空間。 4)本廠電(電液)動閥門出廠時均已調(diào)試好，用戶剛開始使用時，為防止接線錯誤，先手動將閥門開至半開狀態(tài)，再接通電源進(jìn)行空載試開。 5)氣(液)動閥門氣源必須保證供給足夠氣(液)壓。 6)安裝時各螺栓要均勻擰緊。 7)安裝時不能強(qiáng)烈撞擊閥門或任意擰動閥門零部件。 8)閥門上密封處外露的，須定期加注密封脂類。 9)在較為干燥的地區(qū)，閥門驅(qū)動裝置為正齒輪時，須定期加注潤滑油。 10)手輪、手柄及傳動機(jī)構(gòu)均不答應(yīng)作起吊用，并嚴(yán)禁碰撞。南京雙向密封刀閘閥廠家</p><p
