手動翻闆式三(sān)杆蝶(dié)閥，廣(guǎng)泛适(shì)用于建材、玻璃、礦山、電力(lì)、輕工、造紙(zhǐ)等(děng)行業的(de)能源輸(shū)送管道(dào)的煤氣、天然氣、通風、環保工程(chéng)等管道(dào)系(xì)統中。對管道中(zhōng)氣體介質按不同控(kòng)制信(xìn)号調節流(liú)量大小(xiǎo)和切斷(duàn)。

  this valve is widely used in the pipe system transporting coal gas, natural gas, venting and environment protection in building material, glass, mining, power, light industry and papermaking departments. the technique is introduced from foreign company. it can change the flow and cut off gas medium in the pipe by the different control signal.

  手動(dòng)翻闆式三杆蝶(dié)閥具有結構獨特、耐(nài)磨損、流阻損(sǔn)失(shī)小、密封性(xìng)強、自鎖(suǒ)性(xìng)可靠(kào)、操作(zuò)靈活(huó)、指示(shì)方位明(míng)确(què)、維護(hù)方便(biàn)、密封面無(wú)磨損、使用壽命(mìng)長等優點，尤其傳動軸(zhóu)部(bù)分采(cǎi)用外部密封，易調整、易(yì)更(gèng)換無需(xū)停(tíng)機，從而有(yǒu)效地杜絕外漏(lòu)。采用多種(zhǒng)密封(fēng)形式(shì)能适應不同的(de)介(jiè)質，特别(bié)适(shì)用于調節切(qiē)斷和要求快速(sù)自保的場合。配(pèi)用蝸(wō)輪(lún)傳動裝置，可實(shí)現啟閉(bì)操作(zuò)，是調節流(liú)量的理想(xiǎng)設(shè)備(bèi)。

  the valve has the features of compact structure, endurance, little in the lost of flow resistance, good seal, reliable self-locking, flexible operation, definite direction, easy to maintenance and long life. the seal of driving shaft is out seal, which is easy to be adjusted and changed without stopping, so the out leakage is avoided effectively. all kinds of seal type can suit different medium. it is especially suitable in the condition of adjusting, cutting off and self-protecting quickly. the valve is used with worm gear driving device to form a complete set to realize open-close operation. it is the ideal equipment of adjusting flow.
